    To systematically evaluate the evidence for effectiveness of supportive periodontal care (SPC) provided in specialist care and general practice for patients with chronic periodontitis; to construct a model for the cost effectiveness of SPC. Electronic database searches of MEDLINE, EMBASE and SCOPUS were performed with hand searching of relevant journals and Workshops of Periodontology. SPC for patients with chronic periodontitis, at least 12 months follow-up and clinical attachment level as a primary outcome. Three articles addressed the question (Nyman et al. 1975, Axelsson & Lindhe 1981, Cortellini et al. 1994): Deltas CAL for patients undergoing "specialist" SPC were 0.1 mm (2 years), 0.2 mm (6 years) and -0.01 mm (3 years) respectively. In generalist care the Deltas CAL during SPC were -2.2, -1.8 and -2.8 mm. Differences between specialist and generalist SPC were an extra 20.59 tooth years and 3.95 mm attachment loss for generalist SPC. Incremental cost-effectiveness ratios were an extra 288 euros for one tooth year or an extra 1503 euros/1 mm reduction in loss of attachment for SPC delivered in specialist care. SPC delivered in specialist as compared with general practice will result in greater stability of clinical attachment but this will be achieved at relatively greater cost.

    Full Text Available This study examined the predictors of loss to follow-up in long-term supportive periodontal therapy in patients with chronic periodontitis.A total of 280 patients with moderate to severe chronic periodontitis in a tertiary care hospital in China were investigated and followed over the course of study. Questionnaires on clinical and demographic characteristics, self-efficacy for oral self-care and dental fear at baseline were completed. Participants were followed to determine whether they could adhere to long-term supportive periodontal therapy. Binary logistic regression analysis was used to examine the association between clinical and demographic characteristics, self-efficacy for oral self-care, dental fear and loss to follow-up in long-term supportive periodontal therapy.The loss to follow-up in long-term supportive periodontal therapy was significantly associated with age [adjusted OR = 1.042, 95% confidence interval (CI: 1.012-1.074, p = 0.006], severe periodontitis [adjusted OR = 4.892, 95%CI: 2.280-10.499, p<0.001], periodontal surgery [adjusted OR = 11.334, 95% CI: 2.235-57.472, p = 0.003], and middle and low-scoring of self-efficacy scale for self-care groups. The adjusted ORs of loss to follow-up for the middle- (54-59 and low-scoring groups (15-53 were 71.899 (95%CI: 23.926-216.062, p<0.001 and 4.800 (95% CI: 2.263-10.182, p<0.001, respectively, compared with the high-scoring SESS group (60-75.Age, severity of periodontitis, periodontal surgery and the level of self-efficacy for self-care may be effective predictors of loss to follow-up in long-term supportive periodontal therapy in patients with chronic periodontitis.

    The aim of this guidance is to support the dental team to; manage patients with periodontal diseases in primary care appropriately; improve the quality of decision making for referral to secondary care; improve the overall oral health of the population. It focuses on the prevention and non-surgical treatment of periodontal diseases and implant diseases in primary care. The surgical treatment of periodontal and implant diseases and the management of patients by periodontal specialists or in a secondary care setting are outwith the scope of this guidance and are not discussed in detail. The guidance is based on existing guidelines, including those from the British Society of Periodontology, relevant systematic reviews, research evidence and the opinion of experts and experienced practitioners. The methodological approach is based on the international standards set out by the Appraisal of Guidelines Research and Evaluation (AGREE) Collaboration (www.agreetrust.org). The guiding principle for developing guidance within SDCEP is to first source existing guidelines, policy documents, legislation or other recommendations. Similarly, relevant systematic reviews are also initially identified. These documents are appraised for their quality of development, evidence base and applicability to the remit of the guidance under development. In the absence of these documents or when supplementary information is required, other published literature and unpublished work may be sought.Review and updating. The guidance will be reviewed in three years and updated accordingly. Recommendations are provided for assessment and diagnosis; changing patient behaviour; treatment of gingival conditions; periodontal conditions; long term maintenance; management of patients with dental implants; referral and record keeping. The key recommendations highlighted are: Assess and explain risk factors for periodontal diseases to patients. Screen all patients for periodontal diseases at every routine

    We report a case involving a 12-year follow-up after treatment for chronic periodontitis with furcation involvement. A 54-year-old woman presented with the chief complaint of hypersensitivity. Clinical examination at the first visit revealed 15% of sites with a probing depth ≥4 mm and 35% of sites with bleeding on probing. Initial periodontal therapy was implemented based on a clinical diagnosis of severe chronic periodontitis. Surgical periodontal therapy was subsequently performed at selected sites. For #44, regenerative periodontal therapy using enamel matrix derivative (Emdogain(®)) was selected. For #16, which exhibited a 2- to 3-wall vertical bony defect and class III (mesio-distal) furcation involvement, bone graft was scheduled. Other sites with residual periodontal pockets were treated by open flap debridement. For #37, with a gutter-shaped root, odontoplasty was performed. After reevaluation, the patient was placed on supportive periodontal therapy (SPT). During 12 years of SPT, the periodontal condition remained uneventful in most of the teeth. However, bone resorption was observed in the distal aspect of #37, making the prognosis poor. This indicates the need to continuously monitor risk factors, including inflammation and traumatic occlusion, during SPT. Although some problems still remain, severe periodontitis with furcation involvement was successfully maintained longitudinally with an adequate level of patient compliance and careful SPT.

    We report a case of severe chronic periodontitis treated and longitudinally maintained by a periodontist and dental hygienists. The patient was a 45-year-old woman who presented with the chief complaint of gingival bleeding and tooth mobility. An initial examination revealed generalized gingival inflammation and subgingival calculus in the premolar and molar regions. Premature contact was observed in #14 and 45. Clinical examination revealed 42% of sites with a probing depth (PD) of ≥4 mm and 44% of sites with bleeding on probing. Radiographic examination revealed vertical bone resorption in #35, 36, and 45, and horizontal bone resorption in other regions. Based on a clinical diagnosis of severe chronic periodontitis, initial periodontal therapy consisting of plaque control, scaling and root planing, and removal of an ill-fitting prosthesis was performed. Following suppression of inflammation, occlusal adjustment of premature contact sites was performed. Open flap debridement was performed for teeth with a PD of ≥5 mm. After confirming the stability of the periodontal tissue, final prostheses were placed on #16, 35-37, and 46. Following re-evaluation, the patient was placed on supportive periodontal therapy. It has been 11 years since the patient's first visit, and the periodontal conditions have remained stable. Meticulous periodontal care maintained over a number of years by a periodontist and dental hygienist have yielded a clinically favorable outcome.

    The aim of this review is to present the current status of the occurrence and management of a periodontal abscess during supportive periodontal therapy (SPT). A periodontal abscess depicts typical features and has been described in patients under SPT in clinical trials. Common periodontal pathogens have been observed in this lesion and some etiologic factors may be responsible for its recurrence. This condition can be isolated or associated with factors that can change the prognosis of affected teeth. Although it has been frequently noticed in untreated periodontitis, the periodontal abscess can also occur in patients under SPT and has been regarded as one of the possible complications of SPT. Patients with a high susceptibility to periodontal disease lost more teeth than those with a healthy periodontium. Early diagnosis and appropriate intervention for periodontal abscesses in patients under SPT are extremely important for the management of the periodontal abscess since this condition can lead to loss of the involved tooth. A single case of a tooth diagnosed with periodontal abscess that responds favorably to adequate treatment does not seem to affect its longevity. An accurate diagnosis and adequate treatment can preserve the longevity of affected teeth.

    A comprehensive plan for periodontal disease (PD) care in Taiwan provides non-surgical and supportive periodontal treatment. The aim of this study was to determine whether the care plan could improve the oral health-related quality of life of patients with PD.This study was conducted by purposive sampling and a quasi-experimental design. Patients with PD were assigned to either comprehensive periodontal treatment (n = 32) or a simple cleaning regimen (n = 32). Their oral health-related quality of life (OHRQoL) was measured using the Taiwanese version of the Brief World Health Organization Quality of Life (WHOQOL-BREF) scale (general QoL) and the Oral Health Impact Profile (OHIP-14) (OHRQoL). Both scales were completed 14, 28, and 90 days after the initial assessment. The extent of PD in the experimental group was determined again at the end of the study.On the 28-item WHOQOL-BREF scale, the scores of the experimental group were higher than those of the control group on 5 items and the environmental domain at 14 days. There was a significant improvement in the experimental group on 2 items at 28 days and at 90 days after periodontal treatment (both P improvement in the experimental group in total score at 28 and 90 days after periodontal treatment (both P plan for PD care showed some improvement in QoL, including in the environmental domain, and on the total score for OHRQoL. Comprehensive periodontal treatment also alleviated periodontal symptoms.

    Periodontal disease is independently associated with cardiovascular disease. Identification of periodontal disease as a risk factor for incident ischemic stroke raises the possibility that regular dental care utilization may reduce the stroke risk. In the ARIC (Atherosclerosis Risk in Communities) study, pattern of dental visits were classified as regular or episodic dental care users. In the ancillary dental ARIC study, selected subjects from ARIC underwent fullmouth periodontal measurements collected at 6 sites per tooth and classified into 7 periodontal profile classes (PPCs). In the ARIC study 10 362 stroke-free participants, 584 participants had incident ischemic strokes over a 15-year period. In the dental ARIC study, 6736 dentate subjects were assessed for periodontal disease status using PPC with a total of 299 incident ischemic strokes over the 15-year period. The 7 levels of PPC showed a trend toward an increased stroke risk (χ 2 trend P periodontal disease). Periodontal disease was significantly associated with cardioembolic (hazard ratio, 2.6; 95% confidence interval, 1.2-5.6) and thrombotic (hazard ratio, 2.2; 95% confidence interval, 1.3-3.8) stroke subtypes. Regular dental care utilization was associated with lower adjusted stroke risk (hazard ratio, 0.77; 95% confidence interval, 0.63-0.94). We confirm an independent association between periodontal disease and incident stroke risk, particularly cardioembolic and thrombotic stroke subtype. Further, we report that regular dental care utilization may lower this risk for stroke. © 2018 American Heart Association, Inc.

    The need for dental implants is increasing, and supportive periodontal treatment can achieve long-term success and prevent peri-implantitis. Contributing factors to noncompliance with long-term scheduled supportive periodontal treatment remain unclear. To investigate whether demographic and clinical characteristics are associated with noncompliance, the authors analyzed data for patients who had received dental implants. The authors recruited patients participating in a supportive periodontal treatment program after receiving permanent prostheses on implants placed from 2005 to 2013. Demographic data and dental treatment histories were collected. Compliance was defined as a record of participation in a standard supportive periodontal treatment program for at least 1 year. The chi-square test, log-rank test, Kaplan-Meier survival curve, and Cox proportional hazards model were used for statistical analysis. The study included 120 patients (259 implants, 60% compliance). The two groups (compliant and noncompliant) differed significantly in frequency distributions for sex (P = .0017), educational level (P = .0325), and histories of substance use (P = .0016), periodontitis (P = .0005), and root planing or flap surgery (P = .0002). The Kaplan-Meier survival curves and log-rank test showed that increases in cumulative continuation rates were significantly associated with male sex (P = .0025); body mass index ≥ 24 kg/m² (P = .0093); and a history of periodontitis (P implant placement, root planing or flap surgery was the crucial factor in determining compliance with supportive periodontal treatment. However, well-designed large-scale studies with a larger sample size are needed to confirm the findings of this study.

    Supportive periodontal care is a crucial aspect of the management of chronic periodontitis and peri-implantitis and is inevitably a long-term commitment for both the clinician and the patient. The principal goals of supportive care are to achieve a high standard of plaque control, minimize bleeding and maintain pockets at less than 6 mm. Gain of attachment around natural teeth during supportive periodontal care has been reported, although gain of attachment and of bone during supportive care may be a more pragmatic and aspirational aim in the longer term. Furthermore, we occasionally see patients for whom, despite excellent home and professional care (surgical or nonsurgical), including the management of risk factors, supportive periodontal care appears to be failing and therefore for such patients the clinician needs to consider further management options. This review considers, in particular, the options of using local or systemically delivered antimicrobials to eradicate periodontal and peri-implant disease progression and discusses the extent to which culture and sensitivity testing before the prescription of systemically delivered antimicrobials may be a cost-effective alternative to prescribing 'blind'. © 2017 John Wiley & Sons A/S.

  11. Point-of-care diagnosis of periodontitis using saliva: technically feasible but still a challenge

    Full Text Available Periodontitis is a chronic inflammation of the periodontium caused by persistent bacterial infection that leads to the breakdown of connective tissue and bone. Because the ability to reconstruct the periodontium is limited after alveolar bone loss, early diagnosis and intervention should be the primary goals of periodontal treatment. However, periodontitis often progresses without noticeable symptoms, and many patients do not seek professional dental care until the periodontal destruction progresses to the point of no return. Furthermore, the current diagnosis of periodontitis depends on time-consuming clinical measurements. Therefore, there is an unmet need for near-patient testing to diagnose periodontitis. Saliva is an optimal biological fluid to serve as a near-patient diagnostic tool for periodontitis. Recent developments in point-of-care (POC testing indicate that a diagnostic test for periodontitis using saliva is now technically feasible. A number of promising salivary biomarkers associated with periodontitis have been reported. A panel of optimal biomarkers must be carefully selected based on the pathogenesis of periodontitis. The biggest hurdle for the POC diagnosis of periodontitis using saliva may be the process of validation in a large, diverse patient population. Therefore, we propose the organization of an International Consortium for Biomarkers of Periodontitis, which will gather efforts to identify, select, and validate salivary biomarkers for the diagnosis of periodontitis.

    A new concept of tele-periodontics, which merges the innovative technology of telecommunications and the field of periodontics, is proposed. This new field of tele-periodontics will have an infinite potential where access to a specialist will be provided at a grass root level, enhancing effective delivery of therapy and information to the rural and under privileged areas. It would allow the specialist and the patient to interact either by video conferencing (real time) or through supportive information (store and forward) over geographic distances. Different probabilities of tele-periodontics such as tele consultation, tele training, tele education and tele support are also discussed in this paper.

    Periodontitis is a bacterially-induced, chronic inflammatory disease that destroys the connective tissues and bone that support teeth. Active periodontal treatment aims to reduce the inflammatory response, primarily through eradication of bacterial deposits. Following completion of treatment and arrest of inflammation, supportive periodontal therapy (SPT) is employed to reduce the probability of re-infection and progression of the disease; to maintain teeth without pain, excessive mobility or persistent infection in the long term, and to prevent related oral diseases.According to the American Academy of Periodontology, SPT should include all components of a typical dental recall examination, and importantly should also include periodontal re-evaluation and risk assessment, supragingival and subgingival removal of bacterial plaque and calculus, and re-treatment of any sites showing recurrent or persistent disease. While the first four points might be expected to form part of the routine examination appointment for periodontally healthy patients, the inclusion of thorough periodontal evaluation, risk assessment and subsequent treatment - normally including mechanical debridement of any plaque or calculus deposits - differentiates SPT from routine care.Success of SPT has been reported in a number of long-term, retrospective studies. This review aimed to assess the evidence available from randomised controlled trials (RCTs). To determine the effects of supportive periodontal therapy (SPT) in the maintenance of the dentition of adults treated for periodontitis. Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 8 May 2017), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2017, Issue 5), MEDLINE Ovid (1946 to 8 May 2017), and Embase Ovid (1980 to 8 May 2017).

    Risk assessment has become a regular feature in both dental practice and society as a whole, and principles used to assess risk in society are similar to those used in a clinical setting. Although the concept of risk assessment as a prognostic indicator for periodontal disease incidence and activity is well established in the management of periodontitis, the use of risk assessment to manage the practical treatment of periodontitis and its sequelae appears to have less foundation. A simple system of initial risk assessment - building on the use of the Basic Periodontal Examination (BPE), clinical, medical and social factors - is described, linked to protocols for delivering care suited to general dental practice and stressing the role of long-term supportive care. The risks of not treating the patient are considered, together with the possible causes of failure, and the problems of successful treatment are illustrated by the practical management of post-treatment recession.

    To compare the clinical and microbiological effects of ultrasonic mechanical instrumentation (UMI) associated to home-care use of amine fluoride/stannous fluoride (AmF/SnF(2) )-containing mouthrinse and toothpaste in smoker and non-smoker patients affected by generalized aggressive periodontitis (G-AgP) during a recall session of supportive periodontal therapy (SPT). Thirteen smokers and 25 non-smokers G-AgP patients enrolled in an SPT programme received a single session of UMI associated with home-care use of AmF/SnF(2) -containing mouthrinse and toothpaste. Clinical and microbiological parameters were assessed pre-treatment, at 6 and 12 weeks post-treatment. In both groups, UMI plus AmF/SnF(2) -implemented oral hygiene use determined a significant decrease of total bacterial counts, with non-smokers exhibiting a lower count compared with smokers at 12 weeks. No significant differences were observed between smokers and non-smokers in the counts of total pathogens and red complex species at each observation interval. Clinically, a significant reduction of supragingival plaque, gingival inflammation and probing pocket depth was similarly observed in both groups. A combined mechanical/chemical plaque control approach based on UMI and the use of AmF/SnF(2) agents resulted in the reduction of supragingival plaque deposits, gingival inflammation and subgingival periodontal pathogens in G-AgP patients during SPT, with no substantial difference between smokers and non-smokers. © 2010 John Wiley & Sons A/S.

    Full Text Available Aims: The aim of this study is to assess the patient compliance to supportive and maintenance periodontal therapy and to determine the reason for noncompliance among young adult patients of Namakkal district, India. Materials and Methods: This was a cross-sectional study conducted on 400 patients who underwent periodontal therapy and subsequently recalled for supportive and maintenance periodontal treatment in the Department of Periodontics, Vivekanandha Dental College for Women, Namakkal. Patients age group 25-35 years and of both gender were equally selected and grouped by occupation and socioeconomic status. According to their compliance with appointments, they are categorized as complete compliance, partially compliance and insufficient or noncompliance. Noncompliance and partially compliance patients were contacted and asked to rate their experience and reason for noncompliance. Results: In this study, 80% of patients showed complete compliance and were regular for supportive periodontal therapy appointments. Women were more regular in maintaining recall appointments than men. Salaried employers showed 84.3% complete compliance, while self-employed personals showed 77% complete compliance and 75% of nonworking personals were regular to the appointment schedule. Noncompliance person has quoted lack of time and forgetting the appointment date as a major reason for missed appointments. Conclusions: This study recommends the need for improvement in communication skills of practitioners and weekend appointment for patient undergoing periodontal maintenance therapy.

    To track the initiating and developing process of one case diagnosed as chronic periodontitis accompanied with malformed lingual groove in maxillary lateral incisor and report the long-term prognosis to the periodontal conservative and supportive therapy. The patient was diagnosed with mild chronic periodontitis 6 years ago and accepted routine periodontal scaling and root planning (SRP) plus supportive periodontal therapy (SPT) one time. Two years later the periodontal condition deteriorated by deep pockets in molars and severe bone destruction around the maxillary lateral incisor with malformed lingual groove. After SRP in sites which pocket depth more than 4mm plus root canal therapy and lingual groove plasty of maxillary right lateral incisor, the SPT regularly proceeded at 3rd, 6th and 12th month. At present the whole periodontal tissue was healthy, the bone lesion around maxillary lateral incisor recovered well, the tooth had no mobile, the cosmetic effect andtooth function was in good state, and the patient was very satisfied.

    This volume of Periodontology 2000 represents the 25th anniversary of the Journal, and uses the occasion to assess important advancements in periodontology over the past quarter-century as well as the hurdles that remain. Periodontitis is defined by pathologic loss of the periodontal ligament and alveolar bone. The disease involves complex dynamic interactions among active herpesviruses, specific bacterial pathogens and destructive immune responses. Periodontal diagnostics is currently based on clinical rather than etiologic criteria, and provides limited therapeutic guidance. Periodontal causative treatment consists of scaling, antiseptic rinses and occasionally systemic antibiotics, and surgical intervention has been de-emphasized, except perhaps for the most advanced types of periodontitis. Plastic surgical therapy includes soft-tissue grafting to cover exposed root surfaces and bone grafting to provide support for implants. Dental implants are used to replace severely diseased or missing teeth, but implant overuse is of concern. The utility of laser treatment for periodontitis remains unresolved. Host modulation and risk-factor modification therapies may benefit select patient groups. Patient self-care is a critical part of periodontal health care, and twice-weekly oral rinsing with 0.10-0.25% sodium hypochlorite constitutes a valuable adjunct to conventional anti-plaque and anti-gingivitis treatments. A link between periodontal herpesviruses and systemic diseases is a strong biological plausibility. In summary, research during the past 25 years has significantly changed our concepts of periodontitis pathobiology and has produced more-effective and less-costly therapeutic options. © 2017 John Wiley & Sons A/S.

    Prepubertal periodontitis affects both primary and permanent dentition. The purpose of this study was to examine the composition of subgingival microflora of the permanent dentition in an 11-year-old Caucasian female, who had premature exfoliation of her deciduous teeth on her 5th year of age, and the response of this condition to the antibiotic therapy and supportive periodontal care. Gingival tissues were highly inflamed and alveolar bone loss was detected radiographically. The girl had experienced frequent upper respiratory tract infections, tonsilitis and recurrent otitis media. Her mother had history of early onset periodontitis associated with chronic idiopathic neutropenia. Blood chemistry tests and immunological examinations were also performed. Subgingival plaque samples were collected from the proximal sites of permanent molars, incisors, canines and maxillary premolars. 27 different microbial species were isolated from the subgingival microflora. Among the predominant species were Porphyromonas gingivalis (17.6%-7.3%), Prevotella intermedia (12.4%-4.7%), Capnocytophaga sputigena (14.4%-10.4%), Capnocytophaga ochracea (13.2%-6.9%) and Actinobacillus actinomycetemcomitans (9.3%-5.5%). Periodontal treatment consisted of scaling, root planing in conjunction with antibiotic administration of Augmentin 312.5 mg and Flagyl 200 mg, each t.i.d. for 10 days. 3 weeks after the antibiotic therapy, bacterial samples were collected from the same sites. All the periodontal pathogens were recovered in lower levels and A.actinomycetemcomitans was almost eliminated in the 3-week period. The evaluation of clinical indices at 3, 6 and 12 months showed that periodontal treatment in conjunction with antibiotics was effective and rapidly followed by marked clinical improvement. The microbiological monitoring at 3, 6 and 12 months after antibiotic treatment and each time prior to supportive periodontal care, revealed that the periodontal pathogens fluctuated in low levels even

    This study aimed to evaluate clinically the effect of a novel dentifrice containing three kinds of bactericidal ingredients on periodontal disease. This was a single-arm, prospective clinical study that enrolled patients with periodontitis undergoing supportive periodontal therapy. Periodontal examination, microbiological testing of saliva samples, and evaluation of inflammatory markers (IL-1β, IL-6, IL-8, TNF-α) in gingival crevicular fluid were performed. After 4 weeks of the use of test dentifrice, these parameters were re-evaluated. The use of dentifrice was also subjectively evaluated by clinicians and participants. Among 30 participants, there were significant improvements in the periodontal and microbiological parameters, and the level of interleukin-1β in the gingival crevicular fluid, following the use of the test dentifrice. In clinicians' subjective evaluation of the overall usefulness of the dentifrice, 'mild' and 'moderate' improvement accounted for 83% of the total responses. In the participants' subjective evaluation, the majority indicated their experience of the use as favorable. Within the limitations of this study, it is suggested that the progression of periodontal disease during the supportive periodontal therapy can be prevented by the use of the test dentifrice.

    Full Text Available Aims and Objectives: Estimation of changes in C-reactive protein (CRP level and pregnancy outcome after nonsurgical supportive periodontal therapy in pregnant women affected with Periodontitis. Materials and Methods: A total of 100 pregnant females with periodontitis were assigned to treatment and control groups. All the details about previous and current pregnancies were obtained. Full-mouth periodontal examination was done at baseline, which included oral hygiene index simplified plaque index, gingival index, and clinical attachment loss. CRP level was also measured from collected blood sample initially at baseline and later after the delivery in both the group. Subjects in the treatment group received nonsurgical periodontal treatment during the second trimester of gestational period, and those in the control group did not receive any periodontal therapy during this period. Periodontal therapy included mechanical plaque control instructions and scaling and root planning. Outcome measures assessed were changes in CRP levels, gestational age, and birth weight of the infants. When delivery occurred at 0.05. Conclusion: Nonsurgical supportive periodontal therapy may lower the risk of preterm delivery in females affected with periodontitis by reducing CRP level.

    Full Text Available The correlation between endodontic-periodontal lesion has been documented well be researches. Endodontic lesion originates from pulp, while periodontal lesion originates from periodontal tissues. Anatomically they are connected by apical foramen, lateral canal and accessories, as well as dentin tubules. The correlation appeared as the endodontic defect can be from periodontal lesion, or a periodontal defect is from a pulp tissue. Together they can emerge and form a combination lesion. Endodontic infections have been highly correlated with deeper periodontal pockets and furcation involvement in mandibular, the causal relationship between the two pathoses has not yet been established. This consensus supports the influence of degenerated or inflamed pulp that can happen on the periodontium; but not all researchers agree about the effect of periodontal disease on the pulp. Conclusion: The mechanism of endo-perio lesion need to taken care in order to have appropriate diagnostic so that the right therapy would be able to keep the teeth in the oral cavity.

    This population-based analysis examined the prevalence of periodontal diseases along with the self-perceived oral health and patterns of dental care utilization of breast cancer survivors in the United States. Data from the 1999-2004 National Health and Nutrition Surveys were utilized, examining information from 3,354 women between 50 and 85 years of age. Primary outcomes were gingivitis and periodontitis, self-perceived oral health, and dental care utilization. Logistic regression analyses were used to estimate relationships of breast cancer diagnosis and primary outcomes while controlling for confounding factors. Breast cancer survivors were more likely to be older than 55 years, white, nonsmokers, have higher levels of education and income, and a higher prevalence of osteoporosis. Breast cancer survivors were significantly less likely to have dental insurance (P = 0.04). Utilization of dental services and reason for last dental visit did not significantly differ between groups. A history of a breast cancer diagnosis did not increase the odds of gingivitis [odds ratio (OR):  1.32; 95 percent confidence interval (CI): 0.53-3.63], periodontitis (OR: 1.82; 95 percent CI:  0.89-4.01), or poor self-perceived oral health (OR: 0.89; 95 percent CI: 0.61-1.33) after adjusting for age, race, education, dental care utilization, and smoking status. In this sample, a history of breast cancer does not significantly impact periodontal health, self-perceived oral health, and dental care utilization. However, efforts should be made to assure that breast cancer survivors have dental insurance. © 2015 American Association of Public Health Dentistry.

    Background: Low birth weight is a major public health problem in Pakistan. So there is a need for identification of its modifiable risk factors like periodontitis which will reduce its burden on the society. The objectives of the study were to find out the association between maternal periodontitis and low birth weight in new-borns of all gestational ages delivered in a tertiary care hospital of Abbottabad as well as to see the frequency of periodontitis severity in these subjects. Methods: A hospital-based matched case-control study was conducted among 160 postpartum mothers in Gynaecology/Obstetrics-B ward Ayub Teaching Hospital, Abbottabad. The 80 cases were mothers of low birth weight babies (<2,500 g), the 80 controls were mothers of normal weight babies (=2,500 g) matched with maternal age and gestational age. Data was collected through the hospital records, interview and a periodontal examination. Results: Periodontitis was more in the cases than in the controls (OR: 4.167, 95 percentage CI: 2.142-8.109, ρ=0.000). On multivariate logistic regression, periodontitis was found to be a significant independent risk factor for low birth weight (aOR: 3.173, 95 percentage CI: 1.429-7.047, ρ=0.005). Other significant risk factors were educational level (aOR: 3.408, 95 percentage CI: 1.452-7.996, ρ=0.005), socioeconomic status (aOR: 3.173, 95 percentage CI: 1.366-7.368, ρ=0.007), maternal nutrition (aOR: 3.071, 95 percentage CI: 1.392-6.778, ρ=0.005) and moderate/severe anaemia (aOR: 3.035, 95 percentage CI: 1.052-8.756, p=0.040). Conclusions: Periodontitis is found to be a strong, independent, and clinically significant risk factor for low birth weight. So periodontal therapy should form a part of the antenatal care of the pregnant women in Abbottabad. (author)

    The purpose of this report was to describe the management of an eight-year-old Bulgarian male with Down syndrome presenting with periodontitis as a manifestation of systemic disease in the early mixed dentition. Treatment involved full-mouth mechanical debridement and extraction of hopeless teeth under general anesthesia followed by systemic antibiotics and chemical adjunctive therapy. Microbial culture and sensitivity testing aided in diagnosis and guided treatment decisions. This case report demonstrates a multidisciplinary approach in the management of aggressive periodontal disease in an internationally adopted pediatric patient with special health care needs.

    Increasing evidence suggests that maternal gingivitis and periodontitis may be a risk factor for preterm birth and other adverse pregnancy outcomes. To clarify the possible mechanisms behind the association between periodontal disease and preterm delivery, the authors reviewed studies of the effect of infection with periodontal pathogens in animal models on pregnancy outcomes including fetal growth, placental structural abnormalities and neonatal health. After the first report, in 1996, of a potential association between maternal periodontal disease and delivery of a preterm/low-birth-weight infant in humans, many case control and prospective studies were published. This review summarizes these, as well as early studies involving periodontal intervention to reduce risk. Although there are some conflicting findings and potential problems regarding uncontrolled underlying risk factors, most of the clinical studies indicate a positive correlation between periodontal disease and preterm birth. Recent studies also have shown that there are microbiologic and immunological findings that strongly support the association. The studies indicate that periodontal infection can lead to placental-fetal exposure and, when coupled with a fetal inflammatory response, can lead to preterm delivery. Data from animal studies raise the possibility that maternal periodontal infections also may have adverse long-term effects on the infant's development. Education for patients and health care providers regarding the biological plausibility of the association and the potential risks is indicated, but there is insufficient evidence at this time for health care policy recommendations to provide maternal periodontal treatments for the purpose of reducing the risk of adverse pregnancy outcomes.

    , and the Cochrane Collaboration's tool for risk of bias assessment was used for the critical appraisal of the literature. No studies were identified that assessed primary prevention of CVD in people with periodontitis. One study involving 303 participants with ≥ 50% blockage of one coronary artery or a coronary event within three years, but not the three months prior, was included. The study was at high risk of bias due to deviation from the protocol treatment allocation and lack of follow-up data. The trial compared scaling and root planing (SRP) with community care for a follow-up period of six to 25 months. No data on deaths (all-cause or CVD-related) were reported. There was insufficient evidence to determine the effect of SRP and community care in reducing the risk of CVD recurrence in patients with chronic periodontitis (risk ratio (RR) 0.72; 95% confidence interval (CI) 0.23 to 2.22; very low quality evidence). The effects of SRP compared with community care on high-sensitivity C-reactive protein (hs-CRP) (mean difference (MD) 0.62; -1.45 to 2.69), the number of patients with high hs-CRP (RR 0.77; 95% CI 0.32 to 1.85) and adverse events (RR 9.06; 95% CI 0.49 to 166.82) were also not statistically significant. The study did not assess modifiable cardiovascular risk factors, other blood test results, heart function parameters or revascularisation procedures. We found very low quality evidence that was insufficient to support or refute whether periodontal therapy can prevent the recurrence of CVD in the long term in patients with chronic periodontitis. No evidence on primary prevention was found.

    The objective of this retrospective study was to assess the reasons for tooth loss in a sample of patients who underwent periodontal therapy and supportive periodontal therapy (SPT) in a Brazilian private periodontal practice. A sample of 120 subjects who had been treated and maintained for 10 years or longer was selected from patients attending a periodontal practice. All patients followed a similar treatment: basic procedures, re-evaluation and periodontal surgery where indicated. Reasons for tooth loss were categorized as periodontal, caries, endodontal, root fractures and extraction of retained or partially erupted third molars. Of the 2927 teeth present at the completion of active periodontal treatment, 53 (1.8%) were lost due to periodontal disease, 16 (0.5%) for root fracture, six (0.2%) to caries, five (0.2%) for endodontic reasons and 31 (1.0%) were lost to extraction of retained or partially erupted third molars. Logistic regression analysis was performed to investigate the association between five independent variables with tooth loss due to periodontitis. Only age (> 60 years) and smoking were statistically significant (p < 0.05). The findings of this survey were consistent with previous studies. Older subjects and smokers were more susceptible to periodontal tooth loss. In addition, patients with generalized chronic periodontitis were treated and maintained for long-term periods with low rates of tooth loss.

    Periodontal diseases have several implications for the practice of endodontics. First, advanced periodontitis often has direct implications for the long-term prognosis of the case and requires careful evaluation and coordinated treatment of both the periodontic and endodontic diseases. Second, the potential for functional interactions between odontogenic pathoses and marginal periodontitis requires careful collection of clinical observations and monitoring the outcome of various treatments. In this section, we provide an analysis of recent clinical studies in this area.

    The ultimate goal of periodontal therapy is the regeneration of the tissues destroyed as a result of periodontal disease. Currently, two clinical techniques, based on the principles of "guided tissue regeneration" (GTR) or utilization of the biologically active agent "enamel matrix derivative" (EMD), can be used for the regeneration of intrabony and Class II mandibular furcation periodontal defects. In cases where additional support and space-making requirements are necessary, both of these procedures can be combined with a bone replacement graft. There is no evidence that the combined use of GTR and EMD results in superior clinical results compared to the use of each material in isolation. Great variability in clinical outcomes has been reported in relation to the use of both EMD and GTR, and these procedures can be generally considered to be unpredictable. Careful case selection and treatment planning, including consideration of patient, tooth, site and surgical factors, is required in order to optimize the outcomes of treatment. There are limited data available for the clinical effectiveness of other biologically active molecules, such as growth factors and platelet concentrates, and although promising results have been reported, further clinical trials are required in order to confirm their effectiveness. Current active areas of research are centred on tissue engineering and gene therapy strategies which may result in more predictable regenerative outcomes in the future.

    The acute phase of chronic periodontitis may occur even in patients during supportive periodontal therapy. However, the details are not fully understood. Since the natural environment, including meteorology affects human health, we hypothesized that weather conditions may affect occurrence of acute phase of chronic periodontitis. The aim of this study was to investigate the relationship between weather conditions and acute phase of chronic periodontitis in patients under supportive periodontal therapy. Patients who were diagnosed with acute phase of chronic periodontitis under supportive periodontal therapy during 2011-2013 were selected for this study. We performed oral examinations and collected questionnaires and meteorological data. Of 369 patients who experienced acute phase of chronic periodontitis, 153 had acute phase of chronic periodontitis without direct-triggered episodes. When using the autoregressive integrated moving average model of time-series analysis, the independent covariant of maximum hourly range of barometric pressure, maximum hourly range of temperature, and maximum daily wind speed were significantly associated with occurrence of acute phase of chronic periodontitis (p chronic periodontitis.

    The existence of specific microbial profiles for different periodontal conditions is still a matter of debate. The aim of this study was to test the hypothesis that 40 bacterial species could be used to classify patients, utilising machine learning, into generalised chronic periodontitis (ChP), generalised aggressive periodontitis (AgP) and periodontal health (PH). Subgingival biofilm samples were collected from patients with AgP, ChP and PH and analysed for their content of 40 bacterial species using checkerboard DNA-DNA hybridisation. Two stages of machine learning were then performed. First of all, we tested whether there was a difference between the composition of bacterial communities in PH and in disease, and then we tested whether a difference existed in the composition of bacterial communities between ChP and AgP. The data were split in each analysis to 70% train and 30% test. A support vector machine (SVM) classifier was used with a linear kernel and a Box constraint of 1. The analysis was divided into two parts. Overall, 435 patients (3,915 samples) were included in the analysis (PH = 53; ChP = 308; AgP = 74). The variance of the healthy samples in all principal component analysis (PCA) directions was smaller than that of the periodontally diseased samples, suggesting that PH is characterised by a uniform bacterial composition and that the bacterial composition of periodontally diseased samples is much more diverse. The relative bacterial load could distinguish between AgP and ChP. An SVC classifier using a panel of 40 bacterial species was able to distinguish between PH, AgP in young individuals and ChP. © 2017 FDI World Dental Federation.

    The cytokine, interleukin (IL)-32, is a relatively new discovery. However, it is very powerful for stimulating tumor necrosis factor-alpha (TNF-α) under inflammatory conditions. The objective of this research was to explore fluctuations in the levels of TNF-α, IL-32 and IL-10, in both saliva and gingival crevicular fluid. The focus was on measurements taken before and after clinical treatment of chronic periodontitis. For the purposes of the study, a total of 27 patients with chronic periodontitis and 27 controls (periodontally healthy) were recruited. Important clinical periodontal criteria were established before and 4 wk after the start of the research. The chronic periodontitis group was given an initial form of periodontal care. Samples of saliva and gingival crevicular fluid were collected exactly 4 wk preceding and 4 wk following the care. The levels of IL-10, IL-32 and TNF-α present in saliva and gingival crevicular fluid were recorded via the use of an ELISA. At baseline, the levels of TNF-α and IL-32 in the gingival crevicular fluid and saliva were significantly higher among patients in the chronic periodontitis group than among patients in the control group (p chronic periodontitis group than the control group (p chronic periodontitis group when compared with the baseline readings.

    As the prevalence of periodontitis is more than 40 % in the adult Belgian population, periodontists are clearly understaffed to treat this disease in all patients. Therefore, it seems logic that mild forms of chronic periodontitis are treated by the general practitioner especially because Belgium lacks dental hygienists. Important prerequisites for organizing periodontal care as such relate to the general practitioner who should use the same techniques, have comparable communicative skills to motivate patients and create a similar amount of time for periodontal treatment as the specialist. After all, the patient has the right to qualitative treatment regardless of the level of education of the care provider. In order to guarantee this in general practice as much as possible, there is a need for clinical guidelines developed by specialists. These guidelines should not only support the general practitioner in treating disease; above all, they should assist the dentist in periodontal diagnosis. Hitherto, periodontal screening by general dentists seems to be infrequently performed even though reimbursement of the Dutch Periodontal Screening Index is implemented in the Belgian healthcare security system. In this manuscript possible explanations for this phenomenon are discussed. Apart from the need for guidelines in general practice, guidelines for surgical treatment seem compulsory to uniform treatment protocols in specialized practice. Extreme variation in the recommendation of surgery among Belgian specialists calls for consensus statements.

    Chronic periodontitis is defined as an inflammatory disease of the supporting tissues of teeth caused by microorganisms in the dental biofilm, resulting in progressive destruction of the periodontal ligament and alveolar bone with pocket formation and gingival recession. Treatment of chronic periodontitis aims at arresting the inflammation and stopping the loss of attachment by removal and control of the supra- and subgingival biofilm and establishing a local environment and microflora compatible with periodontal health. The AIM of this study was to evaluate the effectiveness of non-surgical therapy (scaling and root planning) in the treatment of moderate chronic periodontitis. The study included 30 patients aged between 33 and 75 years, of which 46.7% women and 53.3% men, diagnosed with moderate and, at some sites, severe periodontitis. They were treated with non-surgical periodontal therapy methods (scaling and root planning and curettage if indicated). Additionally, chemical plaque control with rinse water containing chlorhexidine was applied. The diagnostic and reassessment procedures included measuring the periodontal indices of 601 periodontal units before and after the therapy. The indices measured were the papillary bleeding index (PBI), the hygiene index (HI), the probing pocket depth (PPD) and the clinical attachment level (CAL). Significant reduction of plaque and gingival inflammation was found in all treated patients; we also found a statistically significant reduction of periodontal pockets with clinically measured depth 5 mm did not show statistically significant lower incidence rates probably due to the initially small percentage of deep pockets in the patients studied. There was a statistically significant reduction of all sites with attachment loss, the highest significance found at sites where the attachment loss was greater than 5 mm. The results of the study suggest that nonsurgical periodontal therapy is effective in managing the moderate

    To examine the attitudes of dental practitioners towards specialist periodontal referral in the North East of England. Semi-structured interviews were conducted with a purposive sample of 10 practitioners. Interviews continued until data saturation occurred. The data were organised using a framework and analysed by two researchers working independently. Perceptions of periodontal disease and treatment appear to be heavily influenced by the NHS remuneration system. Treatment in general practice was limited to simple scaling and there was an apparent reluctance to treat advanced periodontitis. Such cases were commonly referred to specialists, confirming the demand for a referral service in periodontics. The perceived potential for medico-legal consequences was a strong driver of referrals. Distance to the referral centre and the perceived costs of treatment were significant barriers to referral. Dentists valued the specialist's personal reputation and clinical skills more highly than academic status. Deficiencies in communication between primary and secondary care were highlighted. Increased resources are required to manage periodontal diseases within the NHS. There is a need for a periodontal referral service in the North East of England to improve accessibility to specialist care. This would appear to be most appropriately delivered by increased numbers of specialist practitioners.

    Regeneration of mineralized tissues affected by chronic diseases comprises a major scientific and clinical challenge. Periodontitis, one such prevalent disease, involves destruction of the tooth-supporting tissues, alveolar bone, periodontal-ligament and cementum, often leading to tooth loss. In 1997, it became clear that, in addition to their function in enamel formation, the hydrophobic ectodermal enamel matrix proteins (EMPs) play a role in the regeneration of these periodontal tissues. The epithelial EMPs are a heterogeneous mixture of polypeptides encoded by several genes. It was not clear, however, which of these many EMPs induces the regeneration and what mechanisms are involved. Here we show that a single recombinant human amelogenin protein (rHAM(+)), induced in vivo regeneration of all tooth-supporting tissues after creation of experimental periodontitis in a dog model. To further understand the regeneration process, amelogenin expression was detected in normal and regenerating cells of the alveolar bone (osteocytes, osteoblasts and osteoclasts), periodontal ligament, cementum and in bone marrow stromal cells. Amelogenin expression was highest in areas of high bone turnover and activity. Further studies showed that during the first 2 weeks after application, rHAM(+) induced, directly or indirectly, significant recruitment of mesenchymal progenitor cells, which later differentiated to form the regenerated periodontal tissues. The ability of a single protein to bring about regeneration of all periodontal tissues, in the correct spatio-temporal order, through recruitment of mesenchymal progenitor cells, could pave the way for development of new therapeutic devices for treatment of periodontal, bone and ligament diseases based on rHAM(+).

It usually affects people under 30 years of age, but patients may be older. Microbiota associated are Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis. The presence of highly pathogenic bacteria, severe periodontal bone destruction and the refractory nature of this disease tends to deter the clinician from placing implants in these patients. This case report demonstrates the placement of implants in a patient with AgP with successful 18 months follow-up.

    Full Text Available Background: Diabetes is becoming more common in the Greenlandic population. Patients with diabetes are more prone to periodontal disease. Periodontal status may have an effect on metabolic control. Objective: The aim of this study was to estimate the prevalence of periodontitis amongst patients with diabetes in Nuuk, Greenland, and secondly, to observe if dental care was associated with improved periodontal status and metabolic control. Study design: Observational cross-sectional study and a pilot study of a dental care intervention. Methods: Sixty-two Greenlandic patients with diabetes were included in the study. Data were collected from the Electronic Medical Records (EMR, in addition to a telephone interview. Patients were offered 3 dental examinations with a 3-month interval. The dental examinations consisted of a full-mouth assessment of number of remaining teeth and assessment of periodontal status. Patients received scaling and root planing, together with information and instructions on oral hygiene. Information on glycated haemoglobin (HbA1C values was collected from the EMR at each dental examination. Results: In this study, 21.0% (13/62 of patients with diabetes had periodontitis. About 42% had less than 20 teeth. The association between diabetes and periodontitis was known by 20 out of the 62 patients. Over half of the patients had been to a dental examination within the last year. The prevalence of periodontitis decreased significantly from 21.0 to 0% (p<0.001 after 3 dental examinations. No change in HbA1C levels was observed (p=0.440. Conclusion: Periodontitis was common among patients with diabetes in Nuuk. Dental health status based on Periodontal Screening Index (PSI and bleeding on probing (BOP seemed to improve after dental health care, indicating a need for increased awareness among patients and health care professionals. HbA1C levels were not improved among the patients.

    Periodontal diseases are among the most common human infections that not only impact oral health but also are associated with adverse systemic diseases such as cardiovascular diseases, stroke, diabetes, and respiratory diseases. Periodontal diseases is a chronic severe inflammatory process of the gingiva leading to the destruction of tooth-supporting structures, alveolar bone, and subsequently tooth loss due to bacteria infection. While it has been reported that several oral biofilm-forming bacteria might be involved, the role of C. pneumoniae infection in the pathogenesis of periodontal disease remains unknown. The present hypothesis proposes that C. pneumoniae is involved in the pathogenesis of periodontal diseases. This will lead to a better understanding of the etiopathogenesis of periodontal disease, better treatment strategy and savings on total health care costs.

    The periodontal abscess is a frequent periodontal condition in which periodontal tissues may be rapidly destroyed. Its importance is based on the possible need of urgent care, the affectation of tooth prognosis, and the possibility of infection spreading. There is scant information in the scientific literature regarding this condition and most of it has been published as case reports and text books, where conclusions are not evidence-based, but rather empirical observations made by recognised clinicians. The aim of this review was to critically analyse all available information on this subject in the dental and medical literature, including information on its prevalence, proposed etiologies and pathogenesis, diagnosis, microbiology and treatment alternatives. The periodontal abscess is the 3rd most frequent dental emergency, and it is specially prevalent among untreated periodontal patients and periodontal patients during maintenance. Different etiologies have been proposed, and 2 main groups can be distinguished, depending on its relation with periodontal pockets. In the case of a periodontitis-related abscess, the condition may appear as an exacerbation of a non-treated periodontitis or during the course of periodontal therapy. In non-periodontitis related abscesses, impaction of foreign objects, and radicular abnormalities are the 2 main causes. The abscess microflora seems to be similar to that of adult periodontitis, and it is dominated by gram-negative anaerobic rods, including well-known periodontal pathogens. Complications and consequences include tooth loss and the spread of the infection to other body sites. Diagnosis and treatment is mainly based on empiricism, since evidence-based data are not available. The role of systemic antibiotics, in the treatment of periodontal abscesses, is especially controversial.

    Periodontitis is the commonest oral disease affecting population worldwide. This disease is notorious for the devastation of tooth supporting structures, ensuing in the loss of dentition. The etiology for this disease is bacterial biofilm, which accumulates on the teeth as dental plaque. In addition to the biofilm microorganisms, other factors such as environmental, systemic and genetic are also responsible in progression of periodontitis. Diabetes mellitus (DM) is metabolic disorder which has an impact on the global health. DM plays a crucial role in the pathogenesis of periodontitis. Periodontitis is declared as the “sixth” major complication of DM. Evidence based literature has depicted an enhanced incidence and severity of periodontitis in subjects with DM. A “two way” relationship has been purported between periodontitis and DM. Mutual management of both conditions is necessary. Periodontal therapy (PT) may assist to diminish the progression of DM and improve glycemic control. Various advanced technological facilities may be utilized for the purpose of patient education and disease management. The present paper clarifies the etio-pathogenesis of periodontitis, establishing it as a complication of DM and elaborating the various mechanisms involved in the pathogenesis. The role of PT in amelioration of DM and application of digital communication will be discussed. Overall, it is judicious to create an increased patient cognizance of the periodontitis-DM relationship. Conjunctive efforts must be undertaken by the medical and oral health care professionals for the management of periodontitis affected DM patients. PMID:26962409

    Periodontal diseases are prevalent both in developed and developing countries and affect about 20-50% of global population. High prevalence of periodontal disease in adolescents, adults, and older individuals makes it a public health concern. Several risk factors such as smoking, poor oral hygiene, diabetes, medication, age, hereditary, and stress are related to periodontal diseases. Robust evidence shows the association of periodontal diseases with systemic diseases such as cardiovascular disease, diabetes, and adverse pregnancy outcomes. Periodontal disease is likely to cause 19% increase in the risk of cardiovascular disease, and this increase in relative risk reaches to 44% among individuals aged 65 years and over. Type 2 diabetic individuals with severe form of periodontal disease have 3.2 times greater mortality risk compared with individuals with no or mild periodontitis. Periodontal therapy has been shown to improve glycemic control in type 2 diabetic subjects. Periodontitis is related to maternal infection, preterm birth, low birth weight, and preeclampsia. Oral disease prevention strategies should be incorporated in chronic systemic disease preventive initiatives to curtail the burden of disease in populations. The reduction in the incidence and prevalence of periodontal disease can reduce its associated systemic diseases and can also minimize their financial impact on the health-care systems. It is hoped that medical, dental practitioners, and other health-care professionals will get familiar with perio-systemic link and risk factors, and need to refer to the specialized dental or periodontal care.

    Inflammatory periodontal diseases exhibit an association with multiple systemic conditions. Currently, there is a lack of consensus among experts on the nature of these associations and confusion among health care providers and the public on how to interpret this rapidly growing body of science. This article overviews the current evidence linking periodontal diseases to diabetes, cardiovascular disease, osteoporosis, preterm low birth weight babies, respiratory diseases, and rheumatoid arthritis. Evidence was taken from systematic reviews, clinical trials, and mechanistic studies retrieved in searches of the PubMed electronic database. The available data provide the basis for applied practical clinical recommendations. Evidence is summarized and critically reviewed from systematic reviews, primary clinical trials, and mechanistic studies Surrogate markers for chronic periodontitis, such as tooth loss, show relatively consistent but weak associations with multiple systemic conditions. Despite biological plausibility, shorter-term interventional trials have generally not supported unambiguous cause-and-effect relationships. Nevertheless, the effective treatment of periodontal infections is important to achieve oral health goals, as well as to reduce the systemic risks of chronic local inflammation and bacteremias. Inflammatory periodontal diseases exhibit an association with multiple systemic conditions. With pregnancy as a possible exception, the local and systemic effects of periodontal infections and inflammation are usually exerted for many years, typically among those who are middle-aged or older. It follows that numerous epidemiological associations linking chronic periodontitis to age-associated and biologically complex conditions such as diabetes, cardiovascular disease, osteoporosis, respiratory diseases, rheumatoid arthritis, certain cancers, erectile dysfunction, kidney disease and dementia, have been reported. In the coming years, it seems likely that

    Periodontal disease (PD) is the most widespread oral disease in dogs and has been associated with serious systemic diseases. The disease is more prevalent in small breeds compared to large breeds and incidence increases with advancing age. In prevalence studies 84% of Beagles over the age of 3 and 100% of Poodles over the age of 4 were diagnosed with PD. Current knowledge of the rate of progression of PD is limited. The objective of this study was to determine the rate of PD progression in Miniature Schnauzers, an at risk small breed of dog. Dogs (n = 52, age 1.3-6.9 years) who had received a regular oral care regime prior to this study were assessed for levels of gingivitis and periodontitis around the whole gingival margin in every tooth under general anaesthetic. Assessments were conducted approximately every six weeks for up to 60 weeks following the cessation of the oral care regime. All of the 2155 teeth assessed entered the study with some level of gingivitis. 23 teeth entered the study with periodontitis, observed across 12 dogs aged between 1.3 and 6.9 years. 35 dogs had at least 12 teeth progress to periodontitis within 60 weeks. Of the teeth that progressed to periodontitis, 54% were incisors. The lingual aspect of the incisors was significantly more likely to be affected (p periodontitis-affected teeth was variable with 24% of the aspects affected having very mild gingivitis, 36% mild gingivitis and 40% moderate gingivitis. Periodontitis progression rate was significantly faster in older dogs. Only one dog (age 3.5) did not have any teeth progress to periodontitis after 60 weeks. This is the first study to have assessed the progression rate of periodontitis in Miniature Schnauzers and highlights that with no oral care regime, the early stages of periodontitis develop rapidly in this breed. An oral care regime and twice yearly veterinary dental health checks should be provided from an early age for this breed and other breeds with similar

    Clinically defined periodontal disease is highly prevalent, has considerable impacts on individuals and society and is costly to treat; the cost of dental care is the fourth highest costs of all diseases and consuming between 5 and 10% of all healthcare resources. Changes in the epidemiology of clinically defined periodontal diseases suggest that the prevalence of severe periodontal disease is low and rates of progression of periodontal destruction tend to be relatively slow. Current periodontal care modalities have a remarkably weak evidence base, with considerable resources allocated to fund interventions that include oral hygiene instruction, scale and polishes through to surgical interventions. The public health problem lies more in the failure in design of a contract between dental professionals and the state. Such a contract needs to recognise both the wider determinants of disease and the role that dental professionals could play: a contract that concentrated on rewarding outcomes, namely a diminution in treatment need, as opposed to one based simply on the number of interventions would be a major step forward.

  15. Periodontal disease and systemic complications

    2012-01-01

    Full Text Available Periodontal diseases comprise a number of infectious and inflammatory conditions brought about by the interaction between supragingival and subgingival biofilms and the host inflammatory response. Periodontal diseases should be considered systemic conditions. This means that they are both modulated by the body's systems and play a role as a risk factor for systemic derangements. The current evidence supports some of these interactions, such as smoking as a risk factor for periodontal disease and diabetes mellitus, as both influenced by and influencing inflammatory changes in the periodontal tissue. Other potential associations are still being researched, such as obesity, hormonal changes, cardiovascular disease, and adverse outcomes in pregnancy. These, and others, still require further investigation before the repercussions of periodontal disease can be fully elucidated. Nevertheless, at the present time, the treatment of periodontal diseases-and, most importantly, their prevention-enables adequate intervention as a means of ensuring periodontal health.

    The theory of self-efficacy states that specific efficacy expectations affect behaviour. Two types of efficacy expectations are described within the theory. Self-efficacy expectations are the beliefs in the capacity to perform a specific behaviour. Outcome expectations are the beliefs that carrying out a specific behaviour will lead to a desired outcome. To develop and examine the reliability and validity of an outcome expectancy scale for self-care (OESS) among periodontal disease patients. A 34-item scale was tested on 101 patients at a dental clinic. Accuracy was improved by item analysis, and internal consistency and test-retest stability were investigated. Concurrent validity was tested by examining associations of the OESS score with the self-efficacy scale for self-care (SESS) score and plaque index score. Construct validity was examined by comparing OESS scores between periodontal patients at initial visit (group 1) and those continuing maintenance care (group 2). Item analysis identified 13 items for the OESS. Factor analysis extracted three factors: social-, oral- and self-evaluative outcome expectancy. Cronbach's alpha coefficient for the OESS was 0.90. A significant association was observed between test and retest scores, and between the OESS and SESS and plaque index scores. Further, group 2 had a significantly higher mean OESS score than group 1. We developed a 13-item OESS with high reliability and validity which may be used to assess outcome expectancy for self-care. A patient's psychological condition with regard to behaviour and affective status can be accurately evaluated using the OESS with SESS. © 2011 Blackwell Publishing Ltd.

    Successful treatment and prevention of periodontal disease in pet animals requires a multidimensional approach to identify and eliminate exacerbating factors, provide scheduled professional examinations and care, and plan and implement a dental homecare program. Over the years, many therapeutic and preventive interventions have been developed or advocated for periodontal disease, but evidence of efficacy or effectiveness is highly variable. Accordingly, the main objective of this systematic review is to identify and critically appraise the evidence supporting various aspects of homecare for prevention of canine and feline periodontal disease.

    2014-08-01

    Full Text Available INTRODUCTION: Chronic periodontitis is defined as an inflammatory disease of the supporting tissues of teeth caused by microorganisms in the dental biofilm, resulting in progressive destruction of the periodontal ligament and alveolar bone with pocket formation and gingival recession. Treatment of chronic periodontitis aims at arresting the inflammation and stopping the loss of attachment by removal and control of the supra- and subgingival biofilm and establishing a local environment and microflora compatible with periodontal health. The AIM of this study was to evaluate the effectiveness of non-surgical therapy (scaling and root planning in the treatment of moderate chronic periodontitis. MATERIALS AND METHODS: The study included 30 patients aged between 33 and 75 years, of which 46.7% women and 53.3% men, diagnosed with moderate and, at some sites, severe periodontitis. They were treated with non-surgical periodontal therapy methods (scaling and root planning and curettage if indicated. Additionally, chemical plaque control with rinse water containing chlorhexidine was applied. The diagnostic and reassessment procedures included measuring the periodontal indices of 601 periodontal units before and after the therapy. The indices measured were the papillary bleeding index (PBI, the hygiene index (HI, the probing pocket depth (PPD and the clinical attachment level (CAL. RESULTS: Significant reduction of plaque and gingival inflammation was found in all treated patients; we also found a statistically significant reduction of periodontal pockets with clinically measured depth ⋋ 5 mm (PD ⋋ 5 mm. Pockets with PD > 5 mm did not show statistically significant lower incidence rates probably due to the initially small percentage of deep pockets in the patients studied. There was a statistically significant reduction of all sites with attachment loss, the highest significance found at sites where the attachment loss was greater than 5 mm. CONCLUSION

    Full Text Available Objective. The aim of this study was to evaluate the effectiveness of a radial firing tip of an Er,Cr:YSGG laser as an adjunct to a nonsurgical periodontal treatment. Methods. Twelve patients with chronic or aggressive periodontitis were treated by conventional periodontal treatment using ultrasonic devices and hand instruments and, additionally, in two quadrants with an Er,Cr:YSGG laser. A new radial firing tip (RFPT 14-5, Biolase was used with 1.5 W, 30 Hz, 11% air, 20% water, and pulse duration 140 μs. Microbiological smears were taken before treatment, one day after lasing, and three and six months after lasing. Pocket depths of all periodontal sites were measured before and six months after treatment. Results. The total bacterial load of Prevotella intermedia, Tannerella forsythia, Treponema denticola, Fusobacterium nucleatum, Porphyromonas gingivalis, and Aggregatibacter actinomycetemcomitans inside the pocket was reduced significantly throughout the whole examination time. Greater pocket depth reductions were observed in all groups. There was a slight higher reduction of pocket depth in the lased group after six months. Conclusions. These results support the thesis that Er,Cr:YSGG laser supported periodontal treatment leads to a significant reduction of periopathogenes and thereby helps the maintenance of periodontal health.

    Full Text Available Genetics is the study and understanding of the phenomena of heredity and variation. A large number of genes are associated with many systemic conditions. Periodontitis is inflammatory condition of periodontium. Periodontium consists of gingiva, periodontal ligament, cementum, and alveolar bone. It is considered being a multifactorial disease. Studies of animals and humans support the concept that a large number of genes' factor may be associated with periodontitis and clearly play a role in the predisposition and progression of periodontal diseases. It has been proven that genetic factors impair inflammatory and immune responses during periodontal diseases. Research on identifying specific genes causing periodontitis may improve and prevent the disease progression. The aim of this article is to focus on genetic risk factors and its influence for the various forms of periodontal disease.

    There are scarce data on the impact of the periodontal condition in the control of biomarkers in patients with cardiovascular disease (CVD). The aim of this study is to assess whether periodontal inflammation and tissue breakdown are associated with C-reactive protein (CRP) and lipids in patients with stable heart disease. This cross-sectional study included 93 patients with stable coronary artery disease (57 males; mean age: 63.5 ± 9.8 years) who were in outpatient care for at least 6 months. After applying a structured questionnaire, periodontal examinations were performed by two calibrated periodontists in six sites per tooth at all teeth. Blood samples were collected from patients on the day of periodontal examination to determine levels of CRP, lipids, and glycated hemoglobin. Multiple linear regression models were fitted to evaluate the association among different periodontal and blood parameters controlling for sex, body mass index, glycated hemoglobin, use of oral hypoglycemic drugs, and smoking. Overall, the sample presented high levels of periodontal inflammation and tissue breakdown. Unadjusted mean concentrations of triglycerides (TGs), very-low-density lipoprotein cholesterol, and glucose were significantly higher in individuals with severe periodontitis. When multiple linear regression models were applied, number of teeth with clinical attachment loss ≥6 mm and presence of severe periodontitis were significantly associated with higher CRP concentrations. Bleeding on probing was significantly associated with TGs, total cholesterol, and non-high-density lipoprotein cholesterol. In this sample of patients with stable CVD, current periodontal inflammation and tissue breakdown are associated with cardiovascular inflammatory markers, such as CRP and lipid profile.

    This study investigated if chronic obstructive pulmonary disease (COPD) is correlated with periodontitis via periodontal microbiota and if certain bacteria affect periodontitis as well as COPD. Moreover, the study investigated whether suffering from COPD is associated with a decrease in the richness and diversity of periodontal microbiota. Subgingival plaque was obtained from 105 patients. Bacterial DNA was isolated from 55 COPD and 50 non-COPD participants (either with or without periodontitis). 16S rRNA gene metagenomic sequencing was used to characterize the microbiota and to determine taxonomic classification. In the non-periodontitis patients, suffering from COPD resulted in a decrease in bacteria richness and diversity in the periodontal microenvironment. An increase in the genera Dysgonomonas , Desulfobulbus , and Catonella and in four species ( Porphyromonas endodontalis , Dysgonomonas wimpennyi , Catonella morbi , and Prevotella intermedia ) in both COPD and periodontitis patients suggests that an increase in these periodontitis-associated microbiota may be related to COPD. Three genera ( Johnsonella , Campylobacter , and Oribacterium ) were associated with COPD but not with periodontitis. The decrease in the genera Arcanobacterium , Oribacterium , and Streptomyces in COPD patients implies that these genera may be health-associated genera, and the decrease in these genera may be related to disease. These data support the hypothesis that COPD is correlated with periodontitis via these significantly changed specific bacteria.

    Full Text Available Gene polymorphism of cytokines influencing their function has been known as a contributing factor in the pathogenesis of inflammatory diseases of the tooth and implant supporting tissues. The aim of this study was to investigate the association of IL-17R gene polymorphism (rs879576 with chronic periodontitis and periimplantitis in an Iranian population. 73 patients with chronic periodontitis, 37 patients with periimplantitis and 83 periodontally healthy patients were enrolled in this study. 5cc blood was obtained from each subject's arm vein and transferred to tubes containing EDTA. Genomic DNA was extracted using Miller's Salting Out technique. The DNA was transferred into 96 division plates, transported to Kbioscience Institute in United Kingdom and analyzed using the Kbioscience Competitive Allele Specific PCR (KASP technique. Chi-square and Kruskal Wallis tests were used to analyze differences in the expression of genotypes and frequency of alleles in disease and control groups (P-Value less than 0.05 was considered statistically significant. There were no significant differences between periodontitis, periimplantitis with AA, GG, GA genotype of IL-17R gene (P=0.8239. Also comparison of frequency of alleles in SNP rs879576 of IL-17R gene between the chronic periodontitis group and periimplantitis group did not revealed statistically significant differences (P=0.8239. The enigma of IL-17 and its polymorphism-role in periodontitis and periimplantitis is yet to be investigated more carefully throughout further research but this article demonstrates that polymorphism of IL-17R plays no significant role in incidence of chronic periodontitis and Periimplantitis.

Also comparison of frequency of alleles in SNP rs879576 of IL-17R gene between the chronic periodontitis group and periimplantitis group did not revealed statistically significant differences (P=0.8239. The enigma of IL-17 and its polymorphism-role in periodontitis and periimplantitis is yet to be investigated more carefully throughout further research but this article demonstrates that polymorphism of IL-17R plays no significant role in incidence of chronic periodontitis and Periimplantitis.

    Full Text Available Objective: The aim of the study was to evaluate the correlation between CD4+ cell count and viral load with periodontal and dental status in HIV seropositive patient. Methods: Forty HIV seropositive patients were selected from the dental clinic of the Clementino Fraga Hospital in João Pessoa, Paraíba, Brazil. The Community Periodontal Index, Simplified Oral Hygiene Index and Decayed, Missing or Filled Teeth Index were determined. The values of CD4+ lymphocyte count and viral load were collected from the medical records. Descriptive analysis was made and Spearman’s correlation test was applied, with values of p<0.05 being significant. Results: HIV seropositive patients were aged 33 to 47 years (mean = 40 years, 26 were men and 14 women. The mean CD4+ lymphocyte count was 507.82±306.4 cells/mm3, with 41% being a high, 38.5% a medium and 20.5% a low level. Sixty-five percent of the patients had undetectable viral load, 12.5% had a high, 5% a low and 5% a medium viral load. Most patients (87.5% presented with periodontal disease, calculus was the most frequent condition (40%. The mean Decayed, Missing or Filled Tooth Index was 19.7±6.8, with prevalence of the missing component. There was significant statistical correlation between the CD4+ count and the periodontal condition, p=0.046. There was no significant correlation between the CD4+ count and the Decayed, Missing or Filled Teeth Index (p=0.469 and the Simplified Oral Hygiene Index (p=0.189 indexes, and between viral load and Decayed, Missing or Filled Teeth Index (p=0.452, the Simplified Oral Hygiene Index (p=0.158 and Community Periodontal Index (p=0.216. Conclusion: The periodontal condition was influenced to a greater by the CD4+ cell count than the viral load, while there was no correlation between the decayed condition and the CD4+ cell count or the viral load condition.

    Evidence-based practice involves complex and conscientious decision making based not only on the available evidence but also on patient characteristics, situations, and preferences. It recognizes that care is individualized and ever-changing and involves uncertainties and probabilities. The specialty of periodontics has abundant high-level evidence upon which treatment decisions can be determined. This paper offers a brief commentary and overview of the available evidence commonly used in the private practice of periodontics.

  12. Periodontitis and Insulin Resistance: Casual or Causal Relationship?

    Directory of Open Access Journals (Sweden)

    Abhijit N. Gurav

    2012-12-01

    Full Text Available Insulin resistance (IR is now considered as a chronic and low level inflammatory condition. It is closely related to altered glucose tolerance, hypertriglyceridemia, abdominal obesity, and coronary heart disease. IR is accompanied by the increase in the levels of inflammatory cytokines like interleukin-1 and 6, tumor necrosis factor-α. These inflammatory cytokines also play a crucial part in pathogenesis and progression of insulin resistance. Periodontitis is the commonest of oral diseases, affecting tooth investing tissues. Pro-inflammatory cytokines are released in the disease process of periodontitis. Periodontitis can be attributed with exacerbation of IR. Data in the literature supports a "two way relationship" between diabetes and periodontitis. Periodontitis is asymptomatic in the initial stages of disease process and it often escapes diagnosis. This review presents the blurred nexus between periodontitis and IR, underlining the pathophysiology of the insidious link. The knowledge of the association between periodontitis and IR can be valuable in planning effectual treatment modalities for subjects with altered glucose homeostasis and diabetics. Presently, the studies supporting this association are miniscule. Further studies are mandatory to substantiate the role of periodontitis in the deterioration of IR.

    2011-12-01

    Full Text Available Introduction: In the periodontal pathology of the pediatric pacient, the therapeutical management depends on an early, as precise as possible diagnosis, as well as on a correct evaluation of the causes and risk factors involved in such processes. The aim of the study: The paper discusses a clinicostatistical study devoted to the evaluation and comparison of the periodontal health condition of a group of children and teenagers subjected to a local etiological treatment. Materials and method: The experimental study was formed of 70 patients selected from the total number of patients having addressed a dentist. Over the whole period of the therapy, oral hygiene, the aspect of marginal gingiva, and the vitality of the teeth under treatment were carefully monitored. Comparisons between the initial and the final moment were based on: periodontal diagnosis, condition of marginal gingiva, number and depth of periodontal pockets, hygiene and dental mobility. Results: Improvement of the periodontal condition or its maintaining at the initial level was observed in patients with good or satisfactory oral hygiene, which was not the case of those with a scarce hygiene, in whom the periodontal problems evolved. Conclusions: Periodontal management should observe the basic principles of the initial causal, corrective and maintainance therapy. The main elements to be here considered are: age, the extent of patient’s involvement, his / her cooperation and motivation, and the support expressed by the family, all of them reflecting the periodontal diagnosis.

    2017-10-01

    Approximately 40 years ago periodontists began systematically developing the evidence to treat predictably and prevent gingivitis and periodontitis. More recently, periodontists have been among a small group of skilled dental-implant surgeons leading that revolution in dentistry. Today, much of the mild/localized moderate periodontitis is not treated by periodontists, and an increasing number of implants are placed by dentists with limited surgical training. The current field of periodontics includes a broad range of surgical skills and technologies to regenerate predictably destroyed tissues and manage complex interdisciplinary treatment that may, in some way, involve the tissues that support teeth and implants. In addition, periodontal researchers have shown that moderate-to-severe periodontitis increases the systemic inflammatory burden and transient bacteremias that result in a significant independent role for periodontitis in multiple systemic diseases. Although many periodontists have very advanced practices that incorporate certain aspects of the current and near-future dimensions of periodontics, the innovations and technologies have not yet fully integrated throughout the specialty. It is an appropriate time to ask the question: Quo vadis? Which paths have the potential to deliver great value to our patients and to the health-care system? And who will be our patients in the near future? We propose some key capabilities, knowledge and clinical applications. Perhaps most importantly, we propose new partnerships. Much of the vision centers around the application of special diagnostic technologies and surgical skills to help our dental colleagues better manage complex dental and periodontal cases and to deliver on the promise of reducing systemic inflammation sufficiently to enhance medical management of certain chronic diseases and reduce preterm births. The specialty has always been about retaining teeth in good health and in recent years has focused on

    Individuals with special needs are at more risk of dental disease, including periodontal diseases, and have a greater prevalence and incidence of periodontal diseases than the rest of the population. Genetic or medical conditions, and/or the use of prescription medication or recreational substances, may further increase the risk for susceptibility to periodontal disease. The success of preventing or controlling periodontal diseases amongst this group of patients has not been established. Even those individuals who access regular and comprehensive dental care appear to develop periodontal diseases as they age, and this development occurs at a rate comparable to the natural history of the disease. The reasons behind the lack of success of interventions in reducing the incidence of periodontal diseases are complex and part of the lack of success may relate to the professional challenges in treating individuals with special needs. © 2017 John Wiley & Sons A/S.

    2017-01-01

    Full Text Available Introduction: Because dermatoglyphic features are strongly affected by genetic and environmental factors, using it as supportive evidence in the diagnosis of hereditary disorders becomes a reality. Offspring of patients suffering from chronic periodontitis have a high prevalence rate of periodontal breakdown, suggesting strong familial influence. Aims: The present study intends to evaluate and compare the dermatoglyphic patterns in controls and periodontally compromised patients. Settings and Design: A hospital based cross-sectional study was conducted, including a total of 60 individuals, divided into study and control groups of 30 each. The study group included clinically diagnosed periodontitis patients.Materials and Methods: The digital prints were collected using biometric scanner and palmer prints using digital flatbed scanner. Care was taken to ensure that full prints of ridges were obtained. The periodontal status of all 60 participants was assessed clinically for attachment level and pocket depth. Later, Russell's periodontal index was also calculated. Statistical Analysis: The data obtained was subjected to statistical analysis using chi square and Student's t-test. Results: Among the finger ridge patterns, whorl pattern was found to be the most common in the study group whereas loop pattern was the most common in the control group. Mean total finger ridge count in the study group (165.69 ± 25.30 was significantly higher (P = 0.001 than the control group (125.4 ± 16.38. Mean dat angle was significantly higher (P = 0.039 in the study group (60.60 ± 2.76 than the control group (59.20 ± 2.62. Conclusion: Dermatoglyphics may serve as an early predictor in identifying high risk group individuals of developing diseases like periodontitis.

    2012-01-01

    In this present era, when a significant number of patients seeking orthodontic treatment are adults, importance of multidisciplinary treatment approach cannot be overemphasized. Higher susceptibility of plaque accumulation in patients undergoing orthodontic treatment makes involvement of periodontist almost unavoidable. Also, orthodontic treatment frequently results in undesirable periodontal changes which require immediate attention. More recently, orthodontics has been used as an adjunct to periodontics to increase connective tissue support and alveolar bone height. The purpose of this article is to review the adverse effects of orthodontic treatment on the periodontal tissues and to discuss the mutually beneficial relationship shared between the two specialties.

    We report a case of generalized chronic periodontitis and type 2 diabetes mellitus requiring periodontal treatment including regenerative therapy. The patient was a 66-year-old man who presented with the chief complaint of gingival inflammation and mobile teeth in the molar region. He had been being treated for type 2 diabetes mellitus since 1999. His glycated hemoglobin (HbA1c) level was 7.8%. An initial examination revealed sites with a probing depth of ≥7 mm in the molar region, and radiography revealed angular bone defects in this area. Based on a clinical diagnosis of generalized chronic periodontitis, the patient underwent initial periodontal therapy. An improvement was observed in periodontal conditions on reevaluation, and his HbA1c level showed a reduction to 6.9%. Periodontal regenerative therapy with enamel matrix derivative was then performed on #16, 26, and 27. Following another reevaluation, a removable partial denture was fabricated for #47 and the patient placed on supportive periodontal therapy (SPT). To date, periodontal conditions have remained stable and the patient's HbA1c level has increased to 7.5% during SPT. The results show the importance of collaboration between dentist and physician in managing periodontal and diabetic conditions in such patients.

    Atherosclerosis, a chronic inflammatory disease in arterial blood vessels, is one of the major causes of death in worldwide. Meanwhile, periodontal disease is a chronic inflammatory disease caused by infection with periodontal pathogens such as P. gingivalis (Porphyromonas gingivalis). Several studies have reported association between periodontal infection and atherosclerosis, but direct investigation about the effects of periodontal treatment on atherosclerosis has not been reported. We have planned Japanese local clinics to determine the relationship between periodontal disease and atherosclerosis under collaborative with medical and dental care. A prospective, multicentre, observational study was conducted including 38 medical patients with lifestyle-related diseases in the stable period under consultation at participating medical clinics and 92 periodontal patients not undergoing medical treatment but who were consulting at participating dental clinics. Systemic and periodontal examinations were performed before and after periodontal treatment. At baseline, LDL-C (low-density lipoprotein cholesterol) levels and percentage (%) of mobile teeth were positively related to plasma IgG (immunoglobulin) antibody titer against P. gingivalis with multivariate analysis. Corresponding to improvements in periodontal clinical parameters after treatment, right and left max IMT (maximum intima-media thickness) levels were decreased significantly after treatment (SPT-S: start of supportive periodontal therapy, SPT-1y: at 1 year under SPT, and SPT-3y: at 3 years under SPT). The present study has clarified our previous univariate analysis results, wherein P. gingivalis infection was positively associated with progression of atherosclerosis. Thus, routine screening using plasma IgG antibody titer against P. gingivalis and periodontal treatment under collaborative with medical and dental care may prevent cardiovascular accidents caused by atherosclerosis.

    Pregnancy complications, especially low birth weight (defined as birth weight less than 2.500 kilograms (kg)), pre-term delivery (less than 37 weeks) and pre-ecclampsia (elevated maternal blood pressure), continue to be a significant public health issue in both developed and developing countries. Recent data indicate that periodontal disease might confer risk for several systemic disorders. The relationship between periodontal diseases in pregnancy and obstetric complications has been increasingly investigated, showing inconclusive results. The purpose of this study is to review the current literature regarding the influence of periodontal status on pregnancy outcome, including the effect of periodontal treatment. Further research in this area is required, particularly with respect to the effect of population differences on this potential association between periodontal diseases and pregnancy complications as well as on the exact mechanism of this association. Since pregnancy tends to influence periodontal status, and considering the potential reported relation between periodontal disease and pregnancy complications, careful periodontal diagnosis and treatment before as well as during pregnancy is warranted.

    2017-01-01

    Periodontitis is a common inflammatory disease, which is initiated by bacterial infection and subsequently progressed by aberrant host response. It can result in the destruction of teeth supporting tissues and have an influence on systemic health. When periodontitis occurs, reactive oxygen species, which are overproduced mostly by hyperactive neutrophils, could not be balanced by antioxidant defense system and cause tissues damage. This is characterized by increased metabolites of lipid peroxidation, DNA damage and protein damage. Local and systemic activities of antioxidants can also be influenced by periodontitis. Total antioxidant capacity, total oxidant status and oxidative stress index have been used to evaluate the oxidative stress associated with periodontitis. Studies have confirmed that inflammatory response in periodontitis is associated with an increased local and systemic oxidative stress and compromised antioxidant capacity. Our review focuses on increased oxidative stress in periodontal disease, specifically, on the relationship between the local and systemic biomarkers of oxidative stress and periodontitis and their association with the pathogenesis of periodontitis. Also, the relationship between periodontitis and systemic inflammation, and the effects of periodontal therapy on oxidative stress parameters will be discussed. PMID:29180965

    2014-01-01

    Full Text Available Background. Periodontal disease is a chronic inflammatory condition affecting the supporting structures of the dentition. Periodontal destruction is an outcome of the imbalance between matrix metalloproteinases and tissue inhibitors of matrix metalloproteinases (TIMPs. We wanted to prove the hypothesis that salivary TIPM-1 level will vary in different people. A decrease in TIMP-1 level could make them more susceptible to periodontitis whereas a normal level could prevent increased tissue destruction thereby inhibiting the progression from gingivitis to periodontitis. This could probably pave the way for TIPM-1 to be a specific salivary biomarker and serve as a useful diagnostic and therapeutic tool in periodontitis. Methods. Whole unstimulated saliva of 2 ml was collected from twenty-five periodontally healthy and twenty-seven systemically healthy subjects with periodontitis. Clinical parameters recorded at baseline and reevaluated after four weeks in subjects with periodontitis following nonsurgical periodontal therapy were gingival index (GI, oral hygiene index-Simplified (OHI-S, probing pocket depth, and clinical attachment level (CAL. Salivary TIMP-1 levels in both were analyzed using a commercially available ELISA kit.

    Periodontal disease results from inflammation of the supporting structure of the teeth and in response to chronic infection caused by various periodontopathic bacteria. The mechanical removal of this biofilm and adjunctive use of antibacterial disinfectants and antibiotics have been the conventional methods of periodontal therapy. However, the removal of plaque and the reduction in the number of infectious organisms can be impaired in sites with difficult access. Photodynamic therapy (PDT) is a powerful laser-initiated photochemical reaction, involving the use of a photoactive dye (photosensitizer) activated by light of a specific wavelength in the presence of oxygen. Application of PDT in periodontics such as pocket debridement, gingivitis, and aggressive periodontitis continue to evolve into a mature clinical treatment modality and is considered as a promising novel approach for eradicating pathogenic bacteria in periodontitis.

    Teeth affected by combined endodontic-periodontal lesions are usually considered by all prognosis classifications as hopeless teeth. The development of new biomaterials combined with modern endodontic and periodontal regeneration techniques may improve dental prognosis and maintain the affected teeth. Moreover, 1 of the replacement options for those teeth, dental implants, has shown an increasing number of biological and technical complications. Five patients were included in this case series study. Full periodontal and radiographic examination revealed generalized chronic periodontitis. Moreover, endodontic-periodontal lesions affecting single-rooted teeth were detected in those patients with tissue destruction beyond the apex. After splinting those teeth, conventional endodontic and nonsurgical periodontal treatment was performed. Three months later, periodontal regeneration was applied at those teeth in order to reconstruct supporting tissues and to improve dental prognosis. After a follow-up period ranging from 14 months to 17 years, it was observed that all teeth remain asymptomatic and in normal function. No signs of apical pathosis were observed, and the periodontium was stable. All patients were included in a strict maintenance program to check the periodontal and apical status. This case series shows that it is possible to change the prognosis of teeth affected by combined endodontic-periodontal lesions, even if the periodontal support is destroyed beyond the apex.

    Substantial ongoing research continues to explore the contribution of genetics and environment to the onset, extent and severity of periodontal disease(s). Existing evidence supports that periodontal disease appears to have an increased prevalence in family units with a member having aggressive periodontitis. We have been using the nonhuman primate as a model of periodontal disease for over 25 years with these species demonstrating naturally occurring periodontal disease that increases with age. This report details our findings from evaluation of periodontal disease in skulls from 97 animals (5-31 years of age) derived from the skeletons of the rhesus monkeys (Macaca mulatta) on Cayo Santiago. Periodontal disease was evaluated by determining the distance from the base of the alveolar bone defect to the cemento-enamel junction on 1st/2nd premolars and 1st/2nd molars from all four quadrants. The results demonstrated an increasing extent and severity of periodontitis with aging across the population of animals beyond only compensatory eruption. Importantly, irrespective of age, extensive heterogeneity in disease expression was observed among the animals. Linking these variations to multi-generational matriarchal family units supported familial susceptibility of periodontitis. As the current generations of animals that are descendants from these matrilines are alive, studies can be conducted to explore an array of underlying factors that could account for susceptibility or resistance to periodontal disease. © 2016 Wiley Periodicals, Inc.

    2012-04-01

    Full Text Available Periodontitis is a chronic inflammatory process which affects the tooth - supporting structures of the teeth. The disease is initiated by subgingival periopathogenic bacteria in susceptible periodontal sites. The host immune response towards periodontal pathogens helps to sustain periodontal disease and eventual alveolar bone loss. Although scaling and root planing is the standard treatment modality for periodontitis, it suffers from several drawbacks such as the inability to reach the base of deep pockets and doesn’t arrest migration of periodontal pathogens from other sites in the oral cavity. In order to overcome the limitations of scaling and root planning, adjunctive chemotherapeutics and host modulatory agents to the treatment are used. These therapeutic agents show substantial beneficial effects when compared to scaling and root planning alone. This review will cover an update on chemotherapeutic and past and future host immune modulatory agents used adjunctively to treat and manage periodontal diseases.

    This review provides updates on acute conditions affecting the periodontal tissues, including abscesses in the periodontium, necrotizing periodontal diseases and other acute conditions that cause gingival lesions with acute presentation, such as infectious processes not associated with oral bacterial biofilms, mucocutaneous disorders and traumatic and allergic lesions. A periodontal abscess is clinically important because it is a relatively frequent dental emergency, it can compromise the periodontal prognosis of the affected tooth and bacteria within the abscess can spread and cause infections in other body sites. Different types of abscesses have been identified, mainly classified by their etiology, and there are clear differences between those affecting a pre-existing periodontal pocket and those affecting healthy sites. Therapy for this acute condition consists of drainage and tissue debridement, while an evaluation of the need for systemic antimicrobial therapy will be made for each case, based on local and systemic factors. The definitive treatment of the pre-existing condition should be accomplished after the acute phase is controlled. Necrotizing periodontal diseases present three typical clinical features: papilla necrosis, gingival bleeding and pain. Although the prevalence of these diseases is not high, their importance is clear because they represent the most severe conditions associated with the dental biofilm, with very rapid tissue destruction. In addition to bacteria, the etiology of necrotizing periodontal disease includes numerous factors that alter the host response and predispose to these diseases, namely HIV infection, malnutrition, stress or tobacco smoking. The treatment consists of superficial debridement, careful mechanical oral hygiene, rinsing with chlorhexidine and daily re-evaluation. Systemic antimicrobials may be used adjunctively in severe cases or in nonresponding conditions, being the first option metronidazole. Once the acute

    The purpose of this article is to review the current literature on the association between maternal periodontal disease and poor pregnancy and neonatal outcomes and outline the role nurses can play in improving the oral health of pregnant women. Maternal periodontal disease is linked to preterm birth, low birthweight, and preterm low birthweight, but treatment of periodontal disease during pregnancy has been shown to be safe and effective. Nurses, nurse practitioners, and nurse-midwives are in a position to educate pregnant women on the benefits of good oral health and identify and refer women who are in need of dental care for treatment.

    Periodontal tissue is the target tissue of sex hormone, physiological change of sex hormones affects the response of periodontal tissue to bacterial plague. The treatment of periodontal disease of female patients in special periods such as adolescence, menstruation, prepregnancy, pregnancy, puerperium, and menopause should be chosen carefully and correctly. This article attempts to expound these issues.

    Full Text Available Periodontal disease results from inflammation of the supporting structure of the teeth and in response to chronic infection caused by various periodontopathic bacteria. The mechanical removal of this biofilm and adjunctive use of antibacterial disinfectants and antibiotics have been the conventional methods of periodontal therapy. However, the removal of plaque and the reduction in the number of infectious organisms can be impaired in sites with difficult access. Photodynamic therapy (PDT is a powerful laser-initiated photochemical reaction, involving the use of a photoactive dye (photosensitizer activated by light of a specific wavelength in the presence of oxygen. Application of PDT in periodontics such as pocket debridement, gingivitis, and aggressive periodontitis continue to evolve into a mature clinical treatment modality and is considered as a promising novel approach for eradicating pathogenic bacteria in periodontitis.

    Bacterial invasion of the periodontal tissues has been suggested as a relevant step in the etiopathogenesis of periodontal disease. However, its exact importance remains to be defined. The present systematic review assessed the scientific evidence concerning the relationship between the quality or quantity of periodontal microbiota in periodontal tissues and development of periodontal disease. The databases Medline-PubMed, Cochrane-CENTRAL, ISI Web of Knowledge and SCOPUS were searched, up to January 2014. Studies that reported evaluation of periodontal pathogens invasion on human tissues were selected. The screening of 440 title/abstracts elected 26 papers for full-text reading. Twenty three papers were subsequently excluded because of insufficient data or a study protocol not related to the objectives of this systematic review. All included studies were case-control studies that evaluated intracellular or adherent bacteria to epithelial cells from periodontal pockets versus healthy sulci. Study protocols presented heterogeneity regarding case and control definitions and methodological approaches for microbial identification. No consistent significant differences were found related to the presence/absence or proportion of specific periopathogens across the studies, as only one study found statistically significant differences regarding the presence of A. actinomycetemcomitans (p = 0.043), T. forsythia (P periodontal pockets vs. healthy sulci. All studies reported a larger unspecific bacterial load in or on the epithelial cells taken from a diseased site compared to a healthy sulcus. The current available data is of low to moderate quality and inconsistent mainly due to study design, poor reporting and methodological diversity. As so, there is insufficient evidence to support or exclude the invasion by periodontal pathogens as a key step in the etiopathogenesis of periodontal disease. Further research is needed.

    Preterm delivery is associated with high mortality and morbility perinatal, being the costs dispended by the family and the National Health System with preterm newborns extremely high. However, it has been difficult to reduce its incidence due to the various factors involved. There is scientific evidence which support the relationship between periodontal disease and preterm delivery. There is also evidence of tobacco as a risk factor for periodontal disease, even though the relationship with preterm delivery is not yet clear. The aims of our study were to evaluate, in women in a post-partum period, dental and periodontal status as well as the exposure to tobacco and to establish the relationship between these two factors with preterm delivery. We performed a case control study with 237 parturient women from the Department of Obstetrics and Gynecology of Hospital S. João, E.P.E., during the first 48 hours after birth. A total of 86 gave birth at a gestational age under 37 weeks (case group ) and 151 gave birth to term newborns with birthweight equal or superior 2500 g (control group). The prevalence of some indicators of periodontal disease in the studied population was extremely high, namely gingival inflammation and gingival recession, and more of 30% had values of probing depth equal or higher than 4 mm significantly. Based on these periodontal indicators, only the presence of recession in more than two teeth seems to increase the risk of preterm delivery in fivefold (OR = 5,28; IC95%: 1,63-17,04). There is a statistically significant association between probing depth equal or higher than 4mm and smoking during pregnancy. This association might be relevant because 20% of preterm newborns mothers smoked during pregnancy and the proportion that stopped smoking during pregnancy in this group of mothers was almost half of the number of the control group. Therefore it is necessary to embody the information about this thematic in the health education, not only in

  20. [Periodontal abscess: etiology, diagnosis and treatment].

    The periodontal abscess is an acute destructive process in the periodontium resulting in localized collections of pus communicating with the oral cavity through the gingival sulcus or other periodontal sites and not arising from the tooth pulp. The prevalence of periodontal abscess is relatively high and it affects the prognosis of the tooth. Periodontal abscesses can develop on the base of persisting periodontitis but can also occur in the absence of periodontitis. The cause of the development of periodontal abscess originating from chronic periodontitis is the marginal closure of a periodontal pocket, or the pocket lumen might be too tight to drain the increased suppuration due to changes in the composition of subgingival microflora, alteration of bacterial virulence or host defenses. Diagnosis of a periodontal abscess is based on medical and dental history as well as oral examination (pocket depth, swelling, suppuration, mobility, sensibility of the tooth). The most prevalent group of bacteria: P. gingivalis, P. intermedia, B. forsythus, F. nucleatum and P. micros. Previous studies have suggested that the complete therapy of the periodontitis patients with acute periodontal abscess has to do in two stages: the first stage is the management of acute lesions, then the second stage is the appropriate comprehensive treatment of the original and/or residual lesions. The management of acute lesions includes establishing drainage via pocket lumen, subgingival scaling and root planing, curettage of the lining pocket epithelia and seriously inflamed connective tissue, compressing pocket wall to underlying tooth and periodontal support, and maintaining tissue contact. Some authors recommend the incision or to establish drainage and irrigation, or a flap surgery, or even extraction of hopeless teeth. We recommend the use of systemic antibiotics as a preventive measure of systemic disease or in case of systemic symptoms.

    Periodontitis is characterized by an inflammatory response to bacterial infection in the supporting tissues of the teeth. The disease manifests with gingival swelling and bleeding, increased periodontal pocket depth, and alveolar bone loss. Intact bacteria or bacterial products, including lipopolysaccharide (LPS), may enter the bloodstream through inflamed periodontal tissue or via saliva. Bacterial dissemination, further potentiated by gastrointestinal microbiota, may result in endotoxemia a...

    Investigations about possible correlations between vegetarian diet and periodontal conditions are rare and characterized by small case numbers. The aim of this clinical study was to investigate the influence of a vegetarian diet on periodontal parameters with an appropriate sample size. A total of 200 patients, 100 vegetarians and 100 non-vegetarians, were included in the study. All patients were examined including a full mouth assessment of the periodontal and dental conditions. In addition, a questionnaire was handed out to ask for patients' oral hygiene habits and level of education. For statistical analysis the Mann-Whitney Test (χ(2) for analysis of the questionnaire) was applied (level of significance: Pvegetarians versus 41.72 years non-vegetarians). Vegetarians had significantly lower probing pocket depths (P=0.039), bleeding on probing (P=0.001), periodontal screening index (P=0.012), a better hygiene index (Pvegetarians. Furthermore, vegetarians had a higher level of education (PVegetarians revealed better periodontal conditions (less inflammation signs, less periodontal damage and a better dental home care). However, it should be considered that vegetarians are not only avoiding meat in their nutrition but are also characterized by an overall healthier life style.

    Periodontal diseases constitute one of the major global oral health burdens, and periodontitis remains a major cause of tooth loss in adults worldwide. The World Health Organization recently reported that severe periodontitis exists in 5-20% of adult populations, and most children and adolescents exhibit signs of gingivitis. Likely reasons to account for these prevalent diseases include genetic, epigenetic, and environmental risk factors, as well as individual and socio-economic determinants. Currently, there are fundamental gaps in knowledge of such fundamental issues as the mechanisms of initiation and progression of periodontal diseases, which are undefined; inability to identify high-risk forms of gingivitis that progress to periodontitis; lack of evidence on how to prevent the diseases effectively; inability to detect disease activity and predict treatment efficacy; and limited information on the effects of integration of periodontal health as a part of the health care program designed to promote general health and prevent chronic diseases. In the present report, 12 basic, translational, and applied research areas have been proposed to address the issue of global periodontal health inequality. We believe that the oral health burden caused by periodontal diseases could be relieved significantly in the near future through an effective global collaboration.

    There is a strong body of evidence to support the relationship between periodontal diseases and diabetes mellitus. Unless dental practitioners are aware of this link, they cannot apply the information to their daily practice. The aim of the study was, therefore, to evaluate the knowledge of dental practitioners concerning the effect of diabetes on periodontal health. This was a cross-sectional survey of randomly selected dental practitioners in Kuwait. Participants were asked about specific periodontal complications which they believed that patients diagnosed with diabetes were more susceptible to. A total of 220 dental practitioners (133 general dental practitioners and 87 dental specialists) participated in the study. Less than 60% of all study participants reported that tooth loss due to periodontal reasons and periodontal abscess were frequent among diabetic patients. Dental specialists, especially periodontists, were significantly more aware of periodontal complications associated with diabetes. Factors significantly associated with having knowledge about the effect of diabetes on periodontal health in logistic regression analysis were dentists who were older and those who were specialists. The results of this study indicate that knowledge about the effects of diabetes on periodontal health among this sample of dental practitioners is generally low, and dentists may underestimate the outcomes of periodontal diseases in diabetic patients.

    Gingivitis and periodontitis are most common inflammatory diseases of supporting tissues of teeth. Role of microbial etiology and host response in progression of gingival and periodontal diseases has been well established. Because of the beneficial biological effects of ozone, due to its antimicrobial and immunostimulating effect, it is well indicated in the treatment of gingival and periodontal diseases. The objective of this article is to provide a general review about clinical applications of ozone in treatment of periodontal diseases and to summarize the available in vitro and in vivo studies in Periodontics in which ozone has been used.

    Full Text Available The aim of this study was to conduct a literature review to investigate orthodontic treatment in periodontal patients. Periodontal disease causes loss of attachment that results in pathological dental migration Periodontal disease can affect young persons and adults, with a higher incidence in adults, so that the number of adults seeking orthodontic treatment has increased significantly. The periodontal disease must be controlled before the orthodontic treatment begins, and during the treatment it is important to keep the patient motivated as regards control of oral hygiene, with periodical reviews by the periodontist. With regard to assembly of the fixed appliance, special care is required not to place the accessories close to the gingival margin, in addition to using light forces porportional to the amount of periodontal attachment, and kept within the biological limits of movement. Correction of the poorly positioned teeth and controlled orthodontic movement can favor remodeling of the alveolar process in all directions. After orthodontic treatment it is important plan containment individually. Integrated orthodontic-periodontal teamwork is essential for reestablishing a healthy periodontium and satisfactory occlusion.

    To evaluate the effect of non-surgical periodontal therapy on plasma lipid levels in hyperlipidemic patients with chronic periodontitis. After considering the inclusion and exclusion criteria, 30 hyperlipidemic patients with chronic periodontitis in the age group of 30-70 years, undergoing treatment in Ahmed Gasim Cardiac and Renal transplant Centre in north Sudan were recruited for the study. Patients were randomly assigned to the study and control groups. The study group received non-surgical periodontal therapy - oral hygiene instructions, scaling and root planing. The control group participants received only oral hygiene instructions. Lipid profile [total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), triglycerides (TG)], C-reactive protein (CRP), and periodontal parameters [Plaque index (PI), Gingival index (GI), probing pocket depth (PD), and attachment loss (ATL)] were measured and compared at baseline and after 3 months of the respective intervention. Between-groups analysis was done using independent "t" test and within-group analysis was done using dependent "t" test. At baseline, groups were comparable based on lipid profile and periodontal parameters. After 3 months, the control group showed significant decrease in the PI and GI scores while there was no significant change in the other parameters. However, the study group showed significant decrease in the LDL and CRP levels along with a significant decrease in PD, ATL, PI, and GI scores, compared to the baseline values. Local non-surgical periodontal therapy resulted in improved periodontal health, with significant decrease in the LDL and CRP levels in hyperlipidemic patients with chronic periodontitis. Hence, local non-surgical periodontal therapy may be considered as an adjunct in the control of hyperlipidemia, along with standard care.

    We report a case of an elderly patient with chronic periodontitis requiring periodontal surgery. An 86-year-old man presented to Tokyo Dental College Suidobashi Hospital with the chief complaint of tooth fracture in the anterior region and occlusal pain in the posterior region. Clinical examination revealed 47% of sites with a probing depth (PD) of ≥4 mm and 47% of sites with bleeding on probing. Radiographic examination revealed generalized moderate horizontal bone loss with localized vertical defects. A clinical diagnosis of moderate chronic periodontitis was made. The patient's oral health-related quality of life (QoL) was also assessed at the time of each periodontal assessment. Initial periodontal therapy was provided followed by periodontal surgery. Open flap debridement was performed at sites with a PD of ≥5 mm (teeth #15-17). Surgical crown lengthening with an apically positioned flap was performed on #11 and 13 to gain an adequate biological width for the subsequent crown restoration. After confirming the stability of the periodontal tissue, provisional restorations were replaced with final restorations. No further deterioration was observed in the periodontal condition during the subsequent 1-year period of supportive periodontal therapy. Oral health-related QoL was markedly improved by the periodontal therapy. This suggests that periodontal therapy plays an important role in improving and maintaining oral health-related QoL in elderly people.

    Women can experience symptoms of gingival inflammation during pregnancy. However, whether clinical signs of gingival inflammation were present already before pregnancy and whether women perceive an alteration in their periodontal health status during pregnancy compared to their periodontal health status before pregnancy remain unclear. The aim of this study was to evaluate the self-reported periodontal conditions in pregnant Dutch women as perceived before and during pregnancy. This cross-sectional survey was performed by asking women visiting two midwifery practices to complete a structured questionnaire. The data, which considered the women's oral hygiene habits, perceived periodontal health status before and during pregnancy and dental visits, were gathered and analysed. Parametric and nonparametric tests were used when appropriate. Most of the respondents (mean age: 29.6 years) brushed their teeth twice a day (72.2%), and 62.0% used interdental cleaning devices. Significant differences in periodontal health before and during pregnancy were perceived. No differences with respect to periodontal disease symptoms between the three trimesters during pregnancy were found. The symptom with the greatest increase was bleeding gums. This was followed by symptoms of painful and swollen gums. Of the 61.5% women who disclosed their plans to become pregnant to their dental care practitioner, 53.9% received information regarding the possibility of alterations in oral health status during pregnancy. Because of the perceived alterations in oral health status during pregnancy, approximately 11% of the women scheduled an additional appointment with their dental care professional for advice. During the pregnancy period, perceived alterations in periodontal health status were reported as compared to the oral health situation before pregnancy. Furthermore, approximately 50% of the women who visited a dental professional and disclosed their (plans) of pregnancy did not receive

    2014-01-01

    Periodontitis is a chronic inflammatory condition of the tissues that surround and support the teeth and is initiated by inappropriate and excessive immune responses to bacteria in subgingival dental plaque leading to loss of the integrity of the periodontium, compromised tooth function, and eventually tooth loss. Periodontitis is an economically important disease as it is time-consuming and expensive to treat. Periodontitis has a worldwide prevalence of 5–15% and the prevalence of severe disease in western populations has increased in recent decades. Furthermore, periodontitis is more common in smokers, in obesity, in people with diabetes, and in heart disease patients although the pathogenic processes underpinning these links are, as yet, poorly understood. Diagnosis and monitoring of periodontitis rely on traditional clinical examinations which are inadequate to predict patient susceptibility, disease activity, and response to treatment. Studies of the immunopathogenesis of periodontitis and analysis of mediators in saliva have allowed the identification of many potentially useful biomarkers. Convenient measurement of these biomarkers using chairside analytical devices could form the basis for diagnostic tests which will aid the clinician and the patient in periodontitis management; this review will summarise this field and will identify the experimental, technical, and clinical issues that remain to be addressed before such tests can be implemented.

    To day a relatively high percentage of elderly population of the industrialized world suffers with different cardiovascular diseases and are on permanent antihypertensive therapy. One of the most frequently used drugs is the calcium channel blockers prescribed against high blood pressure. The most common oral side effect of these drugs is the gingival enlargement that might develop even on otherwise healthy gingiva. The incidence of chronic periodontitis in this age group is also high and the Ca antagonist medication in those individuals might substantially modify the clinical course of periodontal inflammation leading to gingival enlargement and hypertrophic pocket wall. The case presented here is a 52 years old hypertonic woman with a long history of Ca-antagonist therapy and generalized chronic periodontitis combined with gingival hyperplasia. After the change of medication the 1,5 years comprehensive periodontal endodontic and prosthodontic therapy restored patient's periodontal health and provided complex dental rehabilitation. Nevertheless, only regular periodontal supportive therapy could ensure predictable outcome and guarantee long lasting periodontal health.

    Full Text Available The aim of this work is to analyze the function of natural teeth’s periodontal ligament and the effects of periodontal ligament on implants by the finite element method (FEM, when static functional loads occur. The finite element analysis models are established, which consist of fragment of mandible, natural teeth, periodontal ligament, and implant. Finite element software Abaqus is used to analyze the stress transfer in models with or without periodontal ligament, and mandibular first molar is implant. The implant obtained the maximum stress value of 87.71MPa when periodontal ligament of natural tooth is absent, but the maximum value reduces to 38.43 MPa with the action of periodontal ligament. It illustrates that periodontal ligament has significant effects on stress transfer. When the finite element model of single natural tooth or dentition with implant is generated, periodontal ligament should be taken into account.

    Full Text Available Periodontal maintenance care is an essential part of periodontal therapy for patients diagnosed with Aggressive Periodontitis, being, however, hard to instruct and to motivate these patients to follow a careful and effective program of maintenance for all their lives. A literature review was done, by means of relevant papers published on the last four decades, pointing out the importance of individual susceptibility for the appearance of aggressive periodontitis and to discuss the importance of a maintenance therapy on its treatment, applying Homeopathy and Isopathy. Homeopathy consists on a complex therapeutic system mainly based on the “Law of Similarity”, that is, the illness may be healed by drugs that produce similar symptoms in a healthy organism and, in this conception, the disease is understood as an energetic unbalance, in which internal and external factors acting on the subject’s susceptibility are considered and can be expressed by an individual symptomathology that goes from the rational sphere to the somatic sphere. On the other hand, Isopathy is the method of treatment with therapeutic agent, which actions on a healthy subject consist on pharmacodynamic manifestations similar to those observed in a sick person. Based on these concepts, the authors establish a hypothesis of the effectiveness of Homeopathy and Isopathy, the latter through auto-medications or auto-biotherapies, that are products which the active principal is obtained from the patient himself (gingival tissue and secretions, and that may be used as auxiliary treatments in the maintenance therapy of Aggressive Periodontitis.

    1997-10-01

    This retrospective study focused on the frequency of tooth loss due to periodontal abscess among 42 patients who were treated by a single clinician over a 5- to 29-year period. A total of 114 patients were selected from the active periodontal recall schedule of a single periodontist at The University of Iowa College of Dentistry. The criteria for inclusion in the study included having a history of moderate to advanced periodontitis, being on 3 to 6 month recall periodontal maintenance care, and completion of active periodontal therapy prior to October 1987. Other parameters evaluated were age; gender; number of teeth present and missing at the initial, reevaluation, and last periodontal recall visit; initial periodontal prognosis; furcation involvement; non-surgical and surgical periodontal therapy; and reasons for tooth loss. Patients were grouped according to the number of teeth lost following active periodontal treatment into well-maintained (0 to 3), downhill (4 to 9), and extreme downhill (10 to 23) groups. Forty-two of the 114 patients were identified as having one or more periodontal abscesses. A total of 109 teeth were affected by periodontal abscess of which 49 (45%) teeth were lost and 60 (55%) were successfully maintained over an average of 12.5 years (5 to 29 years). More furcated teeth were lost than nonfurcated teeth and teeth given a hopeless prognosis were lost more consistently than those given a questionable prognosis in all groups. The frequency of periodontal abscess and tooth loss per patient was greater in the downhill and extreme downhill response groups than the well-maintained group. This suggests that teeth with a history of periodontal abscess can be treated and maintained for several years.

    Full Text Available Curettage is used in periodontics to scrap off the gingival wall of a periodontal pocket, and is needed to reduce loss of attachment (LOA by developing new connective tissue attachment in patients with periodontitis. The purpose of this study was to evaluate the success of curettage by the formation of tissue attachment. This clinical experiment was done by comparing LOA before curettage, 2 weeks and 3 weeks after curettage on 30 teeth with the indication of curettage. Study population were periodontitis patient who attending dental clinic at Hospital University Science Malaysia (HUSM with inclusion criteria good general health condition, 18 to 55 years old male or female and presented with pocket depth > 3mm. The teeth were thoroughly scaling before intervention and evaluated by measuring the periodontal attachment before curettage, two weeks and three weeks after curettage. Repeated measure ANOVA and Paired T Test were used to analyze the data. The result of the study showed that there was reduction in the periodontal attachment loss in periodontitis patient after curettage either in the anterior or posterior teeth which were supported by statistical analysis. This study concluded that curettage could make reattachment of the tissue

    The body of research defining relationships among periodontal disease and certain systemic diseases and disorders has been expanding, and questions have been raised regarding what information should be conveyed to health care professionals and patients. Representatives from dentistry, medicine, the academic community and the insurance industry convened a two-day workshop July 23 and 24, 2007. The workshop participants achieved general consensus on a number of issues, including the need for greater cooperation between the health care professions. This cooperation should translate into improved clinical care as physicians refer patients for dental care, and dentists are proactive in regard to the general health of their patients. Communication to health care professionals requires a multifaceted approach that includes publication of research findings in medical and dental journals, cooperation among professional organizations and initiatives at the local level such as presentations at medical grand rounds. Dental schools should play a role in their health science centers. Communication with patients may improve through the use of targeted informational brochures in the offices of medical specialists, appropriate media campaigns and efforts led by local dental organizations. It is too early to provide specific recommendations regarding the treatment of periodontal disease to improve specific health outcomes, but dentists can become advocates for a general health promotion and disease prevention message. The lifestyles approach includes an improved diet, smoking cessation, appropriate hygiene practices and stress reduction. These strategies can improve oral and general health outcomes.

    Periodontitis, a common polymicrobial inflammatory disease in the tooth supporting tissues, is a risk factor for coronary artery disease. One of the proposed underlying mechanisms is the systemic immune response to periodontal infection. We studied how serum antibodies against seven periodontal pathogens and their subgingival levels associate with each other, periodontitis, and coronary artery disease. The Parogene cohort included 505 Finnish patients (mean age 63 y) who underwent coronary angiography, and clinical and radiographic oral examinations. Coronary diagnosis was defined as no significant coronary artery disease (disease (≥50% stenosis, n = 184) and acute coronary syndrome (n = 169). Levels of subgingival Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Porphyromonas endodontalis, Prevotella intermedia, Tannerella forsythia, Campylobacter rectus, and Fusobacterium nucleatum were determined by checkerboard DNA-DNA hybridization. Serum antibody (IgA/IgG) levels were analyzed with enzyme-linked immunosorbent assay (ELISA). Aggregate IgA/IgG burdens were calculated by summing and standardizing the serum antibody levels. Patients with active periodontitis were characterized by higher levels of subgingival bacteria and corresponding IgA/IgG response. Quartiles 2-4 of serum IgA/IgG burden indicated higher risk for acute coronary syndrome (OR 1.84, 95%CI 1.01-3.35 for IgA; OR 1.87, 95%CI 1.01-3.46 for IgG) independently of established cardiovascular risk factors, body mass index, number of teeth, subgingival bacterial levels and periodontal diagnosis. Our findings support the hypothesis that the association between periodontitis and cardiovascular diseases is partly mediated by the immunologic response for periodontal pathogens.

    About 85-94% of the Spanish adults older than 35 experience gum problems, and about 15-30% suffer from periodontitis, being severe in up to 5-11% of them. Unlike other inflammatory conditions, periodontal disease rarely causes discomfort, or limits life or causes functional limitations until its advanced stages, when clinical signs and symptoms arise (gingival recession, pathological teeth migration, or mobility). Lack of knowledge about the disease, together with the idea that tooth loss is linked to ageing, frequently results in a late diagnosis, requiring extensive treatments with a worse prognosis. At Primary Care level, there is series of drugs have been related to periodontal disease (anticonvulsants, immunosuppressive drugs, and calcium channel blockers) as secondary effects, which vary as regards their frequency and severity depending of the amount of accumulated plaque. Stress and depression have also been reported to alter the immune response and to increase the inflammatory response as well as periodontal susceptibility. Certain systemic conditions, such as diabetes mellitus, cardiovascular disorders, respiratory diseases, as well as low-weight pre-term birth, have also been linked to periodontitis.

    Patients with chronic kidney disease (CKD) exhibit increased morbidity and mortality which is associated with an increased systemic inflammatory burden. Identifying and managing comorbid diseases that contribute to this load may inform novel care pathways that could have a beneficial impact on the morbidity/mortality associated with CKD. Periodontitis, a highly prevalent, chronic inflammatory disease affecting the supporting structures of teeth, is associated with an increased systemic inflammatory and oxidative stress burden and the successful treatment of periodontitis has been shown to reduce both. This pilot study aims to gather data to inform a definitive study into the impact of successful periodontal treatment on the cardio-renal health of patients with CKD. This pilot study will employ a randomised, controlled, parallel-group design. Sixty adult patients, with CKD with a high risk of progression and with periodontitis, from the Queen Elizabeth Hospital, Birmingham, will be randomised to receive either immediate, intensive periodontal treatment (n = 30) or treatment at a delay of 12 months (n = 30). Patients will be excluded if they have reached end-stage renal disease or have received specialist periodontal treatment in the previous year. Periodontal treatment will be delivered under local anaesthetic, on an outpatient basis, over several visits by a qualified dental hygienist at the Birmingham Dental Hospital, UK. Patients in the delayed-treatment arm will continue to receive the standard community level of periodontal care for a period of 12 months followed by the intensive periodontal treatment. Randomization will occur using a centralised telephone randomisation service, following baseline assessments. The assessor of periodontal health will be blinded to the patients' treatment allocation. Patients in either arm will be followed up at 3-monthly intervals for 18 months. Aside from the pilot outcomes to inform the practicalities of a larger

    Periodontal disease results from inflammation of the supporting structure of the teeth and in response to chronic infection caused by various periodontopathic bacteria. The mechanical removal of this biofilm and adjunctive use of antibacterial disinfectants and antibiotics have been the conventional methods of periodontal therapy. However, the removal of plaque and the reduction in the number of infectious organisms can be impaired in sites with difficult access. Photodynamic therapy (PDT) is...

    Full Text Available Introduction: High low-density lipoproteins (LDL cholesterol is one of the major risk factors for cardiovascular disease. In recent years, some evidence has been presented that periodontitis,an infectious inflammatory condition of the periodontium, is associated with an increased risk of cardiovascular disease. To further elucidate this association, we have studied the levels of LDL cholesterol, a known risk marker for cardiovascular disease, in a periodontally-diseased group. Methods: The levels of serum LDL cholesterol in 47 subjects with mild to severe (clinical attachment loss equal to or greater than 1 mm chronic generalized (at least 30% of teeth affected periodontitis with the mean age of 42.21 ± 1.46 years were measured and compared with those obtained from 42 age (39.83 ± 0.94 and sex matched controls. Both groups were free from systemic illnesses. Results: The mean serum LDL cholesterol in periodontitis patients was found to be signifi cantly higher (P < 0.001 as compared to that of the controls. The mean clinical attachment loss was positively correlated with serum LDL cholesterol (P < 0.01 and gingival index (P<0.05. The frequency of persons with pathologic values of LDL cholesterol was signifi cantly higher in periodontitis patients compared with that of the controls. Conclusions: These results showed that high serum LDL cholesterol may be associated with periodontitis in healthy people. However, it is unclear whether periodontitis causes an increase in the levels of serum LDL or an increased LDL is a risk factor for both periodontitis and cardiovascular disease. Keywords: Cardiovascular disease, LDL cholesterol, periodontitis.

    Full Text Available Diabetes mellitus is a systemic disease characterized by increased blood glucose levels and abnormalities of lipid metabolism due to absence or decreased level of insulin. It affects all the body organs and their functions either directly or indirectly. Every dentist should have a basic understanding of the etiopathogenesis, oral and systemic manifestations of this disease. The periodontal diseases are a consequence of extension of the gingival inflammation into the underlying supporting structures of the periodontium, initiated by the presence of plaque and its products on the surfaces of the teeth and the adjoining structures. The progression of periodontal disease is influenced by variety of factors like microorganisms, host response, systemic background, and genetic makeup of the host. Amongst them, diabetes mellitus tops the list. Diabetes and periodontitis influence the clinical outcome of each other and control of both influences the clinical improvement of each.

    Periodontitis is an inflammatory disease of the supporting tissues of the teeth induced by periodontopathic bacteria that results in the progressive destruction of periodontal tissues. Treatment of periodontitis is painful and time-consuming. Recently, herbal medicines have been considered for use in treating inflammation-related diseases, including periodontitis. Resveratrol and its derivative 2,3,5,4'-tetrahydroxystilbene-2-O-β-glucoside (THSG), a polyphenol extracted from Polygonum multiflorum, have anti-inflammatory properties and other medical benefits. Here, we highlight the importance of resveratrol and its glycosylated derivative as possible complementary treatments for periodontitis and their potential for development as innovative therapeutic strategies. In addition, we present evidence and discuss the mechanisms of action of resveratrol and THSG on periodontitis, focusing on Porphyromonas gingivalis-induced inflammatory responses in human gingival fibroblasts and animal modeling of ligature-induced periodontitis. We also illuminate the signal transduction pathways and the cytokines involved. © 2017 New York Academy of Sciences.

    Autoimmune reactions reflect an imbalance between effector and regulatory immune responses, typically develop through stages of initiation and propagation, and often show phases of resolution (indicated by clinical remissions) and exacerbations (indicated by symptomatic flares). The fundamental underlying mechanism of autoimmunity is defective elimination and/or control of self-reactive lymphocytes. Periodontal diseases are characterized by inflammatory conditions that directly affect teeth-supporting structures, which are the major cause of tooth loss. Several studies have demonstrated the involvement of autoimmune responses in periodontal disease. Evidence of involvement of immunopathology has been reported in periodontal disease. Bacteria in the dental plaque induce antibody formation. Autoreactive T-cells, natural killer cells, ANCA, heat shock proteins, autoantibodies, and genetic factors are reported to have an important role in the autoimmune component of periodontal disease. The present review describes the involvement of autoimmune responses in periodontal diseases and also the mechanisms underlying these responses. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Aim: The purpose of our study is to study the etiopathogenesis of periodontitis in chronic kidney disease and to identify a correlation between periodontitis and chronic kidney disease, with the help of periodontal exaamination, ultrasonographic and hematobiochemical analysis. Materials and Methods: 46 dogs with renal failure were studied and classified as presenting a slight (56.52%, moderate (36.95% and severe (47.8% degree of periodontal disease. Results: Marked gingival recession involving whole maxillary dental arcade, Oral mucosa ulcers and tissue necrosis and mobility of mandibular incisors was observed in dogs with chronic kidney disease. Dogs with normal renal function were observed to have minimal gingival recession of the mandibular teeth only. Conclusion: In view of the causative association between periodontal infection, generalized inflammation and important systemic diseases like chronic kidney disease, we hypothesize that targeted prophylaxis and careful treatment of oral diseases can prevent the progression of renal failure

    The complement system is a network of interacting fluid-phase and cell surface-associated molecules that trigger, amplify, and regulate immune and inflammatory signaling pathways. Dysregulation of this finely balanced network can destabilize host-microbe homeostasis and cause inflammatory tissue damage. Evidence from clinical and animal model-based studies suggests that complement is implicated in the pathogenesis of periodontitis, a polymicrobial community-induced chronic inflammatory disease that destroys the tooth-supporting tissues. This review discusses molecular mechanisms of complement involvement in the dysbiotic transformation of the periodontal microbiome and the resulting destructive inflammation, culminating in loss of periodontal bone support. These mechanistic studies have additionally identified potential therapeutic targets. In this regard, interventional studies in preclinical models have provided proof-of-concept for using complement inhibitors for the treatment of human periodontitis.

    The oral cavity is a part of the body. The health of the oral cavity affects the health of the entire body. This relationship is reciprocal, as the overall health of an individual will also affect the health of that individual's oral cavity. Periodontal disease is a common, chronic inflammatory disease affecting the supporting structures of the teeth. It has been proposed that periodontal disease is a risk factor for systemic diseases such as diabetes.

    Full Text Available The main aim of the treatment with fixed restoration especially the crowns and bridges is to maintain the remaining teeth of dentition and the whole masticatory system. This treatment can be successful if periodontal consideration of the abutments and the fixed restoration is given. The periodontal of a tooth are gingiva, periodontal ligament, alveolar bone and cementum. The most common type of periodontal disease is gingivitis that usually caused by bacterial plaque attached to tooth or crown surface. The other disease that involve the tooth supporting tissue is called periodontitis, it can be preceded by long standing chronic gingivitis. Trauma from occlusion presents two predominant clinical features, increasing tooth mobility and widening of the periodontal space. Periodontal pocket is a disease of periodontal attachment unit that is caused by the apical migration of the epithelial attachment. Periodontal atrophy occurs as a result of repeated traumatic that cause reduction in height of periodontium. All gingival and periodontal diseases and trauma from occlusion must be eliminated before restorative procedures are begun. Dental fixed restoration and periodontal health are inseparably interrelated. The adaptation of the margins and the contours of the restoration, the surface smoothness, the embrasure and the pontic of a bridge, have a critical biologic impact on the gingiva and supporting periodontal tissue. Dental fixed restoration therefore play a significant role in maintaining gingival and periodontal health. Plaque control must be maintained regularly and the occlusion must be checked at regular intervals after the fixed prosthesis is inserted. The occlusal relationships change with time as the result of micromovement of the natural dentition and the wear of restorative materials.

    Chronic periodontitis, a destructive inflammatory disorder of the supporting structures of the teeth, is prevalent in patients with diabetes. Limited evidence suggests that periodontal therapy may improve glycemic control. To determine if nonsurgical periodontal treatment reduces levels of glycated hemoglobin (HbA1c) in persons with type 2 diabetes and moderate to advanced chronic periodontitis. The Diabetes and Periodontal Therapy Trial (DPTT), a 6-month, single-masked, multicenter, randomized clinical trial. Participants had type 2 diabetes, were taking stable doses of medications, had HbA1c levels between 7% and less than 9%, and untreated chronic periodontitis. Five hundred fourteen participants were enrolled between November 2009 and March 2012 from diabetes and dental clinics and communities affiliated with 5 academic medical centers. The treatment group (n = 257) received scaling and root planing plus chlorhexidine oral rinse at baseline and supportive periodontal therapy at 3 and 6 months. The control group (n = 257) received no treatment for 6 months. Difference in change in HbA1c level from baseline between groups at 6 months. Secondary outcomes included changes in probing pocket depths, clinical attachment loss, bleeding on probing, gingival index, fasting glucose level, and Homeostasis Model Assessment (HOMA2) score. Enrollment was stopped early because of futility. At 6 months, mean HbA1c levels in the periodontal therapy group increased 0.17% (SD, 1.0), compared with 0.11% (SD, 1.0) in the control group, with no significant difference between groups based on a linear regression model adjusting for clinical site (mean difference, -0.05% [95% CI, -0.23% to 0.12%]; P = .55). Periodontal measures improved in the treatment group compared with the control group at 6 months, with adjusted between-group differences of 0.28 mm (95% CI, 0.18 to 0.37) for probing depth, 0.25 mm (95% CI, 0.14 to 0.36) for clinical attachment loss, 13.1% (95% CI, 8

    Coffee is a major dietary source of antioxidants as well as of other anti-inflammatory factors. Given the beneficial role of such factors in periodontal disease, whether coffee intake is associated with periodontal disease in adult males was explored. Existing data collected by a prospective, closed-panel cohort study of aging and oral health in adult males was used. Participants included the 1,152 dentate males in the Veterans Affairs (VA) Dental Longitudinal Study who presented for comprehensive medical and dental examinations from 1968 to 1998. Mean age at baseline was 48 years; males were followed for up to 30 years. Participants are not VA patients; rather, they receive their medical and dental care in the private sector. Periodontal status was assessed by probing depth (PD), bleeding on probing, and radiographic alveolar bone loss (ABL), measured on intraoral periapical radiographs with a modified Schei ruler method. Moderate-to-severe periodontal disease was defined as cumulative numbers of teeth exhibiting PD ≥4 mm or ABL ≥40%. Coffee intake was obtained from participant self-reports using the Cornell Medical Index and food frequency questionnaires. Multivariate repeated-measures generalized linear models estimated mean number of teeth with moderate-to-severe disease at each examination by coffee intake level. It was found that higher coffee consumption was associated with a small but significant reduction in number of teeth with periodontal bone loss. No evidence was found that coffee consumption was harmful to periodontal health. Coffee consumption may be protective against periodontal bone loss in adult males.

  16. Periodontitis and Cognitive Decline in Alzheimer's Disease.

    Directory of Open Access Journals (Sweden)

    Mark Ide

    Full Text Available Periodontitis is common in the elderly and may become more common in Alzheimer's disease because of a reduced ability to take care of oral hygiene as the disease progresses. Elevated antibodies to periodontal bacteria are associated with an increased systemic pro-inflammatory state. Elsewhere raised serum pro-inflammatory cytokines have been associated with an increased rate of cognitive decline in Alzheimer's disease. We hypothesized that periodontitis would be associated with increased dementia severity and a more rapid cognitive decline in Alzheimer's disease. We aimed to determine if periodontitis in Alzheimer's disease is associated with both increased dementia severity and cognitive decline, and an increased systemic pro inflammatory state. In a six month observational cohort study 60 community dwelling participants with mild to moderate Alzheimer's Disease were cognitively assessed and a blood sample taken for systemic inflammatory markers. Dental health was assessed by a dental hygienist, blind to cognitive outcomes. All assessments were repeated at six months. The presence of periodontitis at baseline was not related to baseline cognitive state but was associated with a six fold increase in the rate of cognitive decline as assessed by the ADAS-cog over a six month follow up period. Periodontitis at baseline was associated with a relative increase in the pro-inflammatory state over the six month follow up period. Our data showed that periodontitis is associated with an increase in cognitive decline in Alzheimer's Disease, independent to baseline cognitive state, which may be mediated through effects on systemic inflammation.

    The objectives of this cross-sectional study were: 1) to estimate the prevalence and characterize the severity of periodontal disease in a population of dogs housed in commercial breeding facilities; 2) to characterize PD preventive care utilized by facility owners; and 3) to assess inter-rater reliability of a visual scoring assessment tool. Adult dogs (N = 445) representing 42 breeds at 24 CB facilities in Indiana and Illinois were assessed. Periodontal disease was scored visually using the American Veterinary Dental Collage 0-IV scale. Inter-rater reliability was assessed on 198 dogs and facility owners were asked to provide information about the preventive care utilized. The overall prevalence of periodontal disease (Grades I-IV) was 86.3% (95% CI: 82.9, 89.3). An ordered logistic regression analysis found age (OR = 1.4; 95% CI 1.24, 1.54; Pperiodontal disease increased with increasing age. Additionally, a trend toward decreasing risk with increasing weight was also found, although it was not statistically significant. The trends identified agree with studies that have evaluated periodontal disease in the companion dog population and do not support the assumption that the dental health of dogs in commercial breeding facilities is worse than that of the population as a whole. Although there were few cases of severe periodontal disease and all facilities employed some type of preventive care in this sample, the large number of dogs with some degree of disease (Grades I-IV) suggests that further investigation of preventive care is warranted.

    To describe the prevalence of the cultivable subgingival microbiota in periodontal diseases and to draw attention to the polymicrobial nature of periodontic infections. The study population consisted of 95 patients, 51 females and 44 males, aged 14-62 years. Twenty-nine patients exhibited adult periodontitis (AP), six localized juvenile periodontitis (LJP), and 60 rapidly progressive periodontitis (RPP). Two to four pooled bacterial samples were obtained from each patient. Samples were collected with sterile paper points from the deepest periodontal pockets. The samples were cultured under anaerobic and microaerophilic conditions using selective and non-selective media. Isolates were characterized to species level by conventional biochemical tests and by a commercial rapid test system. Prevotella intermedia and Capnocytophaga spp. were the most frequently detected microorganisms in all diagnostic groups. Porphyromonas gingivalis and Peptostreptococcus micros were found more frequently in AP and RPP patients, while Actinobacillus actinomycetemcomitans and Eikenella corrodens were associated with AP, LJP and RPP patients. The other bacterial species, including Actinomyces spp., Streptococcus spp. and Eubacterium spp., were detected at different levels in the three disease groups. The data show the complexity of the subgingival microbiota associated with different periodontal disease groups, indicating that the detection frequency and levels of recovery of some periodontal pathogens are different in teeth affected by different forms of periodontal disease.

    To evaluate the effect of basic periodontal treatment on clinical periodontal parameters associated with abutment teeth of patients with mandibular Kennedy class I removable partial dentures (RPD) 18 months after treatment. Thirty patients with periodontal disease were treated and evaluated according to the following periodontal parameters: visible plaque index (VPI), bleeding on probing (BOP), probing depth (PD), gingival recession (GR), clinical attachment loss (CAL), and keratinized mucosa (KM). These parameters were compared between abutment teeth with direct and indirect retainers at baseline, and after 6 and 18 months. Data were analyzed by Friedman Test and Wilcoxon Test for all variables. Most patients (n = 26; 86.7%) included in the study were female and had a mean age of 61 years (±7.54). Results showed that VPI and BOP decreased over time, and that VPI values were higher in abutment teeth with direct retainers (p = 0.001). There was a reduction in PD after 6 months, which was maintained up to 18 months. In general, abutment teeth with direct retainers had significantly higher values for PD, GR, and CAL (p = 0.029). Data also indicated that the parameters for VPI, BOP, and PD improved; however, abutment teeth with direct retainers presented smaller improvements, compared with abutment teeth with indirect retainers, which presented significant improvements for almost all variables. Periodontal treatment and oral hygiene care of patients were adequate for maintenance of adequate periodontal conditions, regardless of the use of prostheses. © 2018 by the American College of Prosthodontists.

    To evaluate the existing evidence supporting or refuting the following questions: (i) Do patients with lower vitamin D levels have higher risk for periodontal disease? (ii) Are periodontal treatment outcomes improved by the adjuvant supplementation of vitamin D or by elevated serum vitamin D levels? MEDLINE, SCOPUS, EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched up to September 2017. Studies were included if they had measured serum vitamin D levels or vitamin D intake and any periodontal parameter. Overall, 27 studies were included (13 cross-sectional studies, 6 case-control studies, 5 cohort studies, 2 randomized clinical trials and 1 case series study). Sixty-five percent of the cross-sectional studies reported significant associations between low vitamin D levels and poor periodontal parameters. None of the observational longitudinal studies found that periodontal disease progression could be attributed to lower vitamin D levels. No interventional studies that evaluated the use of vitamin D supplementation as a solely adjuvant to periodontal treatment was found. No meta-analysis was performed due to high variability across studies. The data to support or refute the association between vitamin D levels and periodontal disease are inconclusive at the moment. More rigorously designed longitudinal studies with standardized definitions of periodontal disease and vitamin D are necessary. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  5. Periodontal disease and pregnancy outcomes: time to move on?

    Maternal periodontal disease is a highly prevalent condition that has been studied extensively in relation to adverse pregnancy outcomes, including preterm delivery, preeclampsia, and low birth weight. Investigators speculate that hematogenous transport of bacteria and/or pro-inflammatory mediators from sites of periodontal infection into the placenta, fetal membranes, and amniotic cavity induces pathological processes that lead to these adverse outcomes. Preliminary observational studies supported this hypothesis, but more recent work by our group and others do not demonstrate an increased risk of adverse pregnancy outcomes among women with periodontal disease, and most randomized trials fail to demonstrate improved perinatal outcomes following treatment of periodontal disease in pregnancy.

    Periodontal disease (PD) is a multifactorial inflammatory condition in which inappropriate interaction between the host immune response and specific groups of bacterial pathogens leads to destruction of connective and bone tissues supporting the tooth. Dissemination of pathogens, toxins, and immune complexes from and to periodontal lesions is at the basis of the increasingly recognized association between PD and various systemic diseases (SDs). Considering the growing attention of the medical community to "gender medicine", this review focuses on the association between PD and six systemic conditions heavily impacting women's health, with the aim of providing evidence in support of a joint effort between physicians and dentists to improve clinical management of these conditions. We considered systematic reviews, meta-analyses and narrative reviews evaluating all possible associations between periodontitis, systemic diseases and women. Gender prevalence for PD is discordant, but the literature strongly supports an association between PD and female infertility and adverse pregnancy outcomes. Moreover, PD is bidirectionally linked to several systemic diseases characterized by an established female gender bias, i.e. osteoporosis (OP), cardiovascular diseases (CVD), autoimmunity, Alzheimer's disease (AD) and cancer. Overall, the literature data reviewed here provides a strong foundation for further characterization of molecular and microbial drivers of PD and of several female-prevalent systemic diseases, highlighting the possible importance of a good oral condition in preventing or attenuating women's systemic diseases.

    Previous studies have noted a possible association between periodontal diseases and the risk of various cancers. We assessed cancer risk in a cohort of patients with moderate to severe periodontitis. Patients diagnosed with moderate to severe periodontitis by a periodontist between 2001 and 2010 were identified from the hospital registry. Patients younger than 35 years of age or with a prior cancer diagnosis were excluded. The age- and gender-standardized incidence rates (SIR) were calculated by dividing the number of observed cases by the number of expected cases from Turkish National Cancer Registry 2013 data. A total of 280 patients were included (median age 49.6, 54% female). Median follow-up was 12 years. Twenty-five new cancer cases were observed. Patients with periodontitis had 77% increased risk of cancer (SIR 1.77, 95% CI 1.17-2.58, p = .004). Women with periodontitis had significantly higher risk of breast cancer (SIR 2.40, 95% CI 0.88-5.33) and men with periodontitis had significantly higher risk of prostate cancer (SIR 3.75, 95% CI 0.95-10.21) and hematological cancers (SIR 6.97, 95% CI 1.77-18.98). Although showing a causal association necessitates further investigation, our results support the idea that periodontitis might be associated with increased cancer risk, particularly with hematological, breast and prostate cancers.

    Multiple risk factor syndrome is a clustering of cardiovascular risk factors, such as diabetes, dyslipidemia, hypertension, and obesity associated epidemiologically with insulin resistance. This report describes the clinical course of a patient suffering from severe periodontitis with multiple risk factor syndrome, and discusses the association between periodontal infection and systemic health. The patient had a history of type 2 diabetes, dyslipidemia, and hypertension for over 10 years. At baseline, her hemoglobin A1 c was 8.1%. However, she had no diabetic complications except periodontitis. The IgG antibody titers against Porphyromonas gingivalis FDC 381 and SU63 were elevated above the mean of healthy subjects +2 standard deviations. Intensive periodontal treatment, including periodontal surgery, was performed to reduce periodontal infection and bacteremia. Her systemic and periodontal conditions were evaluated longitudinally for 10 years. Following periodontal treatment, antibody titers against Porphyromonas gingivalis and hemoglobin A1c values were significantly improved. The other clinical data and medication for her systemic condition also remained stable during supportive periodontal therapy. However, she developed myocardial infarction, and showed continuous deterioration of hemoglobin A1 c level and periodontitis. The long-term clustering of risk factors, such as diabetes, dyslipidemia, hypertension, and periodontitis, are associated with the development of myocardial infarction. Treatment of systemic conditions in combination with comprehensive periodontal treatment is important in management of patients with multiple risk factor syndrome.

    In the last 2 decades, a large proportion of studies have focused on the relationship between maternal periodontal disease and poor obstetric outcomes. The aim of the present review is to summarize the current knowledge about human studies on the pathogenetic mechanisms linking periodontal diseases with adverse pregnancy outcomes. A search of the medical literature was conducted using NIH (National Institute of Health) Pubmed through April 2011. Articles were identified with the Medical Subject Heading (MeSH) and free text terms "small for gestational age (SGA)," "preeclampsia," "preterm labor," and "periodontal disease." Experimental human studies have shown that periodontal pathogens may disseminate toward placental and fetal tissues accompanied by an increase in inflammatory mediators in the placenta. As such, new inflammatory reactions within the placental tissues of the pregnant woman may occur, the physiological levels of prostaglandin E(2) (PGE(2)) and tumor necrosis factor-α (TNF-α) in the amniotic fluid may increase and eventually lead to premature delivery. Although many data from clinical trials suggest that periodontal disease may increase the adverse pregnancy outcome, the exact pathogenetic mechanism involved remains controversial. The findings explain the potential link between periodontal infections and adverse pregnancy outcomes. First, periodontal bacteria can directly cause infections both of the uteroplacenta and the fetus; second, systemic inflammatory changes induced by periodontal diseases can activate responses at the maternal-fetal interface. Of note, associative studies have produced different results in different population groups and no conclusive evidence has still been produced for the potential role of preventive periodontal care to reduce the risk factors of preterm birth.

    Periodontitis is a ubiquitous and irreversible inflammatory condition and represents a significant public health burden. Severe periodontitis affects over 11% of adults, is a major cause of tooth loss impacting negatively upon speech, nutrition, quality of life and self-esteem, and has systemic inflammatory consequences. Periodontitis is preventable and treatment leads to reduced rates of tooth loss and improved quality of life. However, successful treatment necessitates behaviour change in patients to address lifestyle risk factors (e.g. smoking) and, most importantly, to attain and sustain high standards of daily plaque removal, lifelong. While mechanical plaque removal remains the bedrock of successful periodontal disease management, in high-risk patients it appears that the critical threshold for plaque accumulation to trigger periodontitis is low, and such patients may benefit from adjunctive agents for primary prevention of periodontitis. The aims of this working group were to systematically review the evidence for primary prevention of periodontitis by preventing gingivitis via four approaches: 1) the efficacy of mechanical self-administered plaque control regimes; 2) the efficacy of self-administered inter-dental mechanical plaque control; 3) the efficacy of adjunctive chemical plaque control; and 4) anti-inflammatory (sole or adjunctive) approaches. Two meta-reviews (mechanical plaque removal) and two traditional systematic reviews (chemical plaque control/anti-inflammatory agents) formed the basis of this consensus. Data support the belief that professionally administered plaque control significantly improves gingival inflammation and lowers plaque scores, with some evidence that reinforcement of oral hygiene provides further benefit. Re-chargeable power toothbrushes provide small but statistically significant additional reductions in gingival inflammation and plaque levels. Flossing cannot be recommended other than for sites of gingival and periodontal

    Mounting evidence suggests a potential association of periodontal disease with systemic diseases such as diabetes, cardiovascular disease, cancer and stroke. The objective of this study is to develop an integrated risk assessment tool that displays a patients' risk for periodontal disease in the context of their systemic disease, social habits and oral health. Such a tool will be used by not just dental professionals but also by care providers who participate in the team-based care for chronic disease management. Displaying relationships between risk factors and its influence on the patient's general health could be a powerful educational and disease management tool for patients and clinicians. It may also improve the coordination of care provided by the provider-members of a chronic care team.

    Full Text Available   Background and Aims: Periodontitis does not affect on all patients by the same way. There are some risk factors in some people that make them more sensitive to progress of periodontitis. Smoking, uncontrolled diabetes, and special pathogens increase the risk of periodontitis. Other factors such as stress, depression and anxiety, are not crucial risk factors for periodontitis yet. Biologic explanation of this relation is that mental conditions and exposure to stressful situations can alter immune response. The aim of this study was to review the psychological factors of anxiety and depression associated with periodontitis.   Materials and Methods: For this review article, we have searched through internet by the following keywords; periodontal disease, anxiety, depression. We have tried to cover almost all dental– related sites and journals as well as Pubmed from 1990-2010.   Conclusion: Most published studies support a positive relationship between periodontitis and several psycho-social factors. Life style, stressful conditions, hormonal changes, nonchalance in oral hygiene, habits such as smoking are predisposing factors in periodontal diseases.

    The events leading to preterm birth are still not completely understood. A quantitative systematic review was performed to estimate the effects of periodontal care during pregnancy on preventing preterm birth and low birth weight. The meta-analysis included randomized trials with pregnant women with a diagnosis of periodontal disease before 20 weeks of gestation. Relative risk (RR) with 95% confidence intervals (95%CI) was calculated. We evaluated the reduction in preterm and low birth weight. Thirteen trials were included, comparing 3,576 women in intervention groups with 3,412 women receiving usual care. The meta-analysis of the effects of periodontal disease treatment during pregnancy indicated a non-significant reduction in preterm births (RR = 0.90; 95%CI: 0.68-1.19) and low birth weights (RR = 0.92; 95%CI: 0.71-1.20). The creation and examination of a funnel plot revealed clear evidence of publication bias. In summary, primary periodontal care during pregnancy cannot be considered an efficient way of reducing the incidence of preterm birth.

  18. Prevalence of periodontitis among the adolescents aged 15-18 years in Mangalore City: An epidemiological and microbiological study

    2013-01-01

    Full Text Available Background: Periodontitis is a group of inflammatory diseases affecting the supporting tissues of the tooth. Both aggressive periodontitis (AP and chronic periodontitis (CP have a multifactorial etiology, with dental plaque as the initiating factor. However, the initiation and progression of periodontitis are influenced by other factors including microbiologic, social and behavioral and systemic and genetic factors. The prevalence of periodontal diseases varies in different regions of the world according to the definition of periodontitis and the study population, and there are indications that they may be more prevalent in developing than in developed countries. Materials and Methods: A cross-sectional study was conducted among the adolescents of 15-18 years of age in Mangalore City. One thousand one hundred students aged 15-18 years were selected for the study from the schools and colleges in Mangalore City using a convenient sampling method. The prevalence of AP and CP were assessed in the study using a community periodontal index. Students who were diagnosed clinically and radiographically were subjected to microbiological examination to confirm AP. Results: A high prevalence of gingivitis and periodontitis was found in students belonging to the lower socioeconomic status group compared with the higher socioeconomic groups, which were associated with poor oral hygiene habits. The prevalence of AP was found to be 0.36% and that of CP was found to be 1.5%. Conclusion: Oral diseases have a significant impact on the social and psychological aspects of an individual′s life. Exposure to risk factors, such as age, low socio-economic status, poor education, low dental care utilization, poor oral hygiene levels, smoking, psychosocial stress and genetic factors are significantly associated with an increased risk of periodontitis among adolescents. Although genetic factors play a major role in periodontitis, the treatment outcome will still be

    Studies have supported the notion that subjects with periodontitis and patients with multiple tooth extractions as a result of chronic advanced periodontal disease (PDD) have a greater risk of developing Cardiovascular disease (CVD) than those who had little or no periodontal infection. Periodontitis may predispose affected patients to CVD by elevating systemic C-reactive protein level and pro-inflammatory activity in atherosclerotic lesions and accelerate development of cardiovascular diseases, Oral health variables including loss of teeth, positive plaque Benzoyl-D-L-Arginine- Naphthyl Amide test (BANA) scores, and compliant of xerostomia may by considered as risk indicators for CVD. Exact mechanism which links PDD and CVD has not been firmly established. The link between PDD and CVD may be attributed to bacteria entering blood stream and attaching to the fatty plaque in coronary artery and contributing to clot formation which can lead to heart attack. Inflammation caused by PDD increases the plaque build up. The association between the two disease entities is cause for concern. However, dental and medical practitioners should be aware of these findings to move intelligently to interact with inquiring patients with periodontitis. They should be urged to maintain medical surveillance of their cardiovascular status, and work on controlling or reducing all known risk factors associated with CVD, including periodontal infection.

    . The difference of serum C-reactive protein levels were significant. However, glycohemoglobin levels were non-significant between non-diabetic periodontitis patients with Grade 1 and Grade 2 mobility. The evidence of association between periodontitis and increased glycohemoglobin increases attention to the diagnosis and treatment of periodontitis, consequently improving the patient's oral health and prevention of occurrence in future diabetes. An understanding of these correlations is important to allow dental health care providers to inform patients with periodontitis of their increased risks and to counsel such patients to seek additional medical assessment or intervention as indicated.

    Periodontitis is an inflammatory disease of gums involving the degeneration of periodontal ligaments, creation of periodontal pocket and resorption of alveolar bone, resulting in the disruption of the support structure of teeth. According to WHO, 10-15% of the global population suffers from severe periodontitis. The disease results from the growth of a diverse microflora (especially anaerobes) in the pockets and release of toxins, enzymes and stimulation of body's immune response. Various local or systemic approaches were used for an effective treatment of periodontitis. Currently, controlled local drug delivery approach is more favorable as compared to systemic approach because it mainly focuses on improving the therapeutic outcomes by achieving factors like site-specific delivery, low dose requirement, bypass of first-pass metabolism, reduction in gastrointestinal side effects and decrease in dosing frequency. Overall it provides a safe and effective mode of treatment, which enhances patient compliance. Complete eradication of the organisms from the sites was not achieved by using various surgical and mechanical treatments. So a number of polymer-based delivery systems like fibers, films, chips, strips, microparticles, nanoparticles and nanofibers made from a variety of natural and synthetic materials have been successfully tested to deliver a variety of drugs. These systems are biocompatible and biodegradable, completely fill the pockets, and have strong retention on the target site due to excellent mucoadhesion properties. The review summarizes various available and recently developing targeted delivery devices for the treatment of periodontitis.

    The purpose of this study was to evaluate the prevalence and severity of periodontitis in men of 65+ years and identify demographic and lifestyle factors associated with its presence. Participants were recruited from the Osteoporotic Fractures in Men Study, a longitudinal study of risk factors for fractures in older men. Dental measures included clinical attachment loss (CAL), pocket depth (PD), calculus, plaque and bleeding on a random half-mouth, plus a questionnaire regarding access to care, symptoms and previous diagnosis. 1210 dentate men completed the dental visit. Average age was 75 years, 39% reported some graduate school education, 32% smoked 20 + pack years and 88% reported their overall health as excellent/good. In terms of periodontal health, 38% had sub-gingival calculus, 53% gingival bleeding, 82% CAL > or =5 mm and 34% PD > or =6 mm. The prevalence of severe periodontitis was 38%. Significant demographic and lifestyle factors associated with severe periodontitis in multivariate analyses included age > or =75 (OR 1.4, 95% CI 1.1-1.7) non-white race (OR 1.9, 95% CI 1.3-2.8), less than an annual dental visit (OR 1.5, 95% CI 1.1-2.0), and 20 + pack years (OR 2.1, 95% CI 1.6-2.7). A high proportion of healthy older men have evidence of periodontal destruction which could, given the growing ageing population, have a significant impact on the dental profession's ability to provide preventive and therapeutic care. The population at highest risk of periodontitis in MrOS is older minority men who smoke and do not have annual dental visits.

    Periodontitis, a complex polymicrobial inflammatory disease, is a public health burden affecting more than 100 million people and being partially responsible for tooth loss. Interestingly, periodontitis has a documented higher prevalence in men as compared to women signifying a possible sex/gender entanglement in the disease pathogenesis. Although relevant evidence has treated sex/gender in a simplistic dichotomous manner, periodontitis may represent a complex inflammatory disease model, in which sex biology may interfere with gender social and behavioral constructs affecting disease clinical phenotype. Even when it became clear that experimental oral health research needed to incorporate gender (and/or sex) framework in the hypothesis, researchers overwhelmingly ignored it unless the research question was directly related to reproductive system or sex-specific cancer. With the recognition of gender medicine as an independent field of research, this study challenged the current notion regarding sex/gender roles in periodontal disease. We aimed to develop the methodological and analytical framework with the recognition of sex/gender as important determinants of disease pathogenesis that require special attention. First, we aim to present relevant sex biologic evidence to understand the plausibility of the epidemiologic data. In periodontitis pathogenesis, sex dimorphism has been implicated in the disease etiology possibly affecting the bacterial component and the host immune response both in the innate and adaptive levels. With the clear distinction between sex and gender, gender oral health disparities have been explained by socioeconomic factors, cultural attitudes as well as access to preventive and regular care. Economic inequality and hardship for women have resulted in limited access to oral care. As a result, gender emerged as a complex socioeconomic and behavioral factor influencing oral health outcomes.

    Periodontal disease, which includes gingivitis and periodontitis, is highly prevalent in adults and disease severity increases with age. The relationship between periodontal disease and oral cancer has been examined for several decades, but there is increasing interest in the link between periodontal disease and overall cancer risk, with systemic inflammation serving as the main focus for biological plausibility. Numerous case-control studies have addressed the role of oral health in head and neck cancer, and several cohort studies have examined associations with other types of cancers over the past decade. For this review, we included studies that were identified from either 11 published reviews on this topic or an updated literature search on PubMed (between 2011 and July 2016). A total of 50 studies from 46 publications were included in this review. Meta-analyses were conducted on cohort and case-control studies separately when at least 4 studies could be included to determine summary estimates of the risk of cancer in relation to 1) periodontal disease or 2) tooth number (a surrogate marker of periodontal disease) with adjustment for smoking. Existing data provide support for a positive association between periodontal disease and risk of oral, lung, and pancreatic cancers; however, additional prospective studies are needed to better inform on the strength of these associations and to determine whether other cancers are associated with periodontal disease. Future studies should include sufficiently large sample sizes, improved measurements for periodontal disease, and thorough adjustment for smoking and other risk factors. © The Author 2017.

    Periodontitis is a chronic inflammatory disease that induces the destruction of tooth-supporting tissues, followed by tooth loss. Although several approaches have been applied to periodontal regeneration, complete periodontal regeneration has not been accomplished. Tissue engineering using a combination of cells and scaffolds is considered to be a viable alternative strategy. We have shown that autologous transplantation of periodontal ligament-derived multipotent mesenchymal stromal cell (PDL-MSC) sheets regenerates periodontal tissue in canine models. However, the indications for autologous cell transplantation in clinical situations are limited. Therefore, this study evaluated the safety and efficacy of allogeneic transplantation of PDL-MSC sheets using a canine horizontal periodontal defect model. Canine PDL-MSCs were labeled with enhanced green fluorescent protein (EGFP) and were cultured on temperature-responsive dishes. Three-layered cell sheets were transplanted around denuded root surfaces either autologously or allogeneically. A mixture of β-tricalcium phosphate and collagen gel was placed on the bone defects. Eight weeks after transplantation, dogs were euthanized and subjected to microcomputed tomography and histological analyses. RNA and DNA were extracted from the paraffin sections to verify the presence of EGFP at the transplantation site. Inflammatory markers from peripheral blood sera were quantified using an enzyme-linked immunosorbent assay. Periodontal regeneration was observed in both the autologous and the allogeneic transplantation groups. The allogeneic transplantation group showed particularly significant regeneration of newly formed cementum, which is critical for the periodontal regeneration. Serum levels of inflammatory markers from peripheral blood sera showed little difference between the autologous and allogeneic groups. EGFP amplicons were detectable in the paraffin sections of the allogeneic group. These results suggest that

    Full Text Available Herbal medicines have long been used as a traditional mode of therapy for various ailments in India. They are being used increasingly as dietary supplements to ward off common diseases. Periodontal diseases are highly prevalent and can affect up to 90% of the world population. Gingivitis is the mild form whereas periodontitis results in an irreversible loss of supporting structures of the teeth. Even though periodontal pathogens form a crucial component in the etiopathogenesis of periodontitis, there is a growing body of evidence suggesting oxidative stress playing a pivotal role in the disease initiation and progression. Studies have shown a direct correlation between increased levels of biomarkers for tissue damage induced by reactive oxygen species (ROS to the severity of periodontal disease. Thus, the focus of attention has revolved back to herbal medicines due to their wide spectrum of biological and medicinal activities, lower costs, and higher safety margin. Internet databases Pubmed and Google Scholar were searched, and the most relevant articles were considered for review. This review briefly describes the various herbs with antioxidant capacity and their potency in the treating periodontal disease. [J Complement Med Res 2016; 5(1.000: 92-96

    The objective of this review was to perform a systematic evaluation of the literature reporting current scientific evidence for periodontal bacteria as contributors to atherosclerosis. Literature from epidemiological, clinical and experimental studies concerning periodontal bacteria and atherosclerosis were reviewed. Gathered data were categorized into seven "proofs" of evidence that periodontal bacteria: 1) disseminate from the oral cavity and reach systemic vascular tissues; 2) can be found in the affected tissues; 3) live within the affected site; 4) invade affected cell types in vitro; 5) induce atherosclerosis in animal models of disease; 6) non-invasive mutants of periodontal bacteria cause significantly reduced pathology in vitro and in vivo; and 7) periodontal isolates from human atheromas can cause disease in animal models of infection. Substantial evidence for proofs 1 to 6 was found. However, proof 7 has not yet been fulfilled. Despite the lack of evidence that periodontal bacteria obtained from human atheromas can cause atherosclerosis in animal models of infection, attainment of proofs 1 to 6 provides support that periodontal pathogens can contribute to atherosclerosis. © 2013 European Federation of Periodontology and American Academy of Periodontology.

    Full Text Available A doença periodontal pode ser definida como a condição inflamatória dos tecidos de suporte do dente em resposta ao acúmulo do biofilme. A consequencia é a formação de graves defeitos ósseos, devido à perda dos tecidos periodontais, levando, em última instância, à perda dos dentes, predisposição a fraturas de mandíbula e formação de comunicações oronasais. O principal tratamento é a prevenção, incluindo a escovação dentária diária e a profilaxia periodontal, procedimento realizado pelo médico veterinário para remoção do biofilme e cálculo dentário acumulados. A recuperação dos tecidos perdidos, ou seja, a regeneração periodontal, é um processo mais complexo, pois envolve a formação de três tecidos intimamente ligados: osso alveolar, ligamento periodontal e cemento. Assim, diversos materiais e técnicas foram e são constantemente desenvolvidos, incluindo membranas para regeneração tecidual guiada e a aplicação de enxertos e biomateriais, amplamente estudados na odontologia humana e já disponíveis para aplicação na rotina clínica veterinária. Adicionalmente, novas possibilidades surgem com a associação dessas técnicas a fatores de crescimento e células-tronco e o desenvolvimento das membranas multifuncionais.Periodontal disease can be defined as the inflammatory condition of the tooth-supportive tissues as a response to biofilm accumulation. The consequence is the formation of severe bone defects due to the loss of periodontal tissues that ultimately lead to tooth loss, predispose to mandible fractures and formation of oronasal communications. The main treatment is prevention, including daily tooth brushing and periodontal prophylaxis, a procedure done by veterinaries to remove retained biofilm and calculus. Recovering lost tissues, i.e. periodontal regeneration, is a more complex process involving the formation of three tissues highly connected: alveolar bone, periodontal ligament and

    Traditional periodontics clinical examinations in dental education frequently assess a narrow set of clinical skills and do not adequately assess the ability of students to independently manage a periodontal patient. As an alternative, the authors developed a comprehensive periodontics competency case experience (CCCE) for senior dental students and surveyed students regarding their experience with the CCCE. Students challenging the CCCE must treat a patient with moderate periodontitis and must independently decide when a state of periodontal and oral health has been achieved. Students are also required to conduct an oral presentation to periodontology faculty. Dental students who completed the CCCE had a favourable impression of the experience, compared with the traditional clinical examinations taken in the junior year. The majority of students rated all the components of the CCCE as 'somewhat' or 'very helpful'. About 72.4% of students felt that being able to work independently on the examination was very helpful for learning about the clinical management of patients with periodontal disease, followed by 'simulation of care in private practice' (65.5%), and oral photography experience (55.2%). The greatest difficulty reported by students was finding an acceptable patient. About 62.1% of students rated 'finding the right patient' as very difficult. Students reported having to screen a mean of 5.9 patients (SD: 4.5) to find a qualified patient. The results of the survey will be useful in improving the examination as an assessment tool in periodontal therapy. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    A variety of systemic diseases and conditions can affect the course of periodontitis or have a negative impact on the periodontal attachment apparatus. Gingival recessions are highly prevalent and often associated with hypersensitivity, the development of caries and non-carious cervical lesions on the exposed root surface and impaired esthetics. Occlusal forces can result in injury of teeth and periodontal attachment apparatus. Several developmental or acquired conditions associated with teeth or prostheses may predispose to diseases of the periodontium. The aim of this working group was to review and update the 1999 classification with regard to these diseases and conditions, and to develop case definitions and diagnostic considerations. Discussions were informed by four reviews on 1) periodontal manifestions of systemic diseases and conditions; 2) mucogingival conditions around natural teeth; 3) traumatic occlusal forces and occlusal trauma; and 4) dental prostheses and tooth related factors. This consensus report is based on the results of these reviews and on expert opinion of the participants. Key findings included the following: 1) there are mainly rare systemic conditions (such as Papillon-Lefevre Syndrome, leucocyte adhesion deficiency, and others) with a major effect on the course of periodontitis and more common conditions (such as diabetes mellitus) with variable effects, as well as conditions affecting the periodontal apparatus independently of dental plaque biofilm-induced inflammation (such as neoplastic diseases); 2) diabetes-associated periodontitis should not be regarded as a distinct diagnosis, but diabetes should be recognized as an important modifying factor and included in a clinical diagnosis of periodontitis as a descriptor; 3) likewise, tobacco smoking - now considered a dependence to nicotine and a chronic relapsing medical disorder with major adverse effects on the periodontal supporting tissues - is an important modifier to be included in

  15. Incorporating Oral Health as Part of Routine Diabetes Care in Ireland

    2017-11-01

    Diabetes mellitus is a common disorder of glucose metabolism that is increasingly prevalent in the Irish population. It is associated with a range of complications leading to substantial morbidity and mortality. A less well-recognized complication of diabetes is periodontal disease. This is a chronic inflammatory disease affecting the periodontium, the specialized group of tissues that surround and support the teeth, including the gingiva (gums) and alveolar bone. Periodontal disease affects patients with diabetes with a greater prevalence and incidence than non-diabetic patients, and can itself exert negative effects on glucose control in people with diabetes. The National Clinical Programme for Diabetes in Ireland aims to reduce the morbidity and mortality associated with diabetes, which includes the development and dissemination of guidelines supporting integrated care. Based on the bidirectional relationship between diabetes mellitus and periodontal disease, we recommend that an oral health evaluation, as well as any necessary onward referral, be incorporated into the Irish recommendations for routine diabetes care, as part of the National Clinical Programme.

    Full Text Available Patients with periodontal disease can lead to severe tooth mobility so often complains of pain when eating, decreased chewing ability and functional occlusion. Tooth mobility is a movement in a horizontal or vertical direction and one of the most unpleased effects from periodontal disease. Basically, tooth mobility is not a disease that requires treatment, but it is a symptom of periodontal tissue morphology changes, so it became a challenge for dentists in making decisions to maintain proper care of the teeth. Recent studies improved the use of periodontal splint with fiber reinforced composite (FRC or fiber composite may lead to a long-term prognosis of teeth mobility due to periodontal disase. The case report describes treatment of chronic periodontitis patients with splinting fiber composites as a method for stabilization of the lower anterior teeth providing aesthetics, comfort, improved functionality occlusion, mastication and a good prognosis.

    Currently there is a growing interest in studying systemic conditions with impact on the periodontium. The aim of this article is to determinate if there is a relation between Hashimoto's thyroiditis and periodontal disease. Founded on periodontology based on evidence and in the combination of the keywords: 'Hashimoto disease'; 'Hypothyroidism'; 'Periodontal disease'; 'Systemic Diseases'; a search and evaluation of articles was conducted in Medline, Scopus and Thomson Reuters databases, selecting 30 articles for integral analysis. There have been developed several studies, searching for a better comprehension about the complexity and pathogenesis of periodontal diseases, associated them to multiple systemic conditions. Actually, the relationship that is best described in the literature is the one with rheumatoid arthritis; however, other relations have been pointed, such as Hashimoto's thyroiditis. The identification of multiple etiopathogenic mechanisms common to Hashimoto's thyroiditis and periodontal disease allow to suspect of a relation between them. Some of these mechanisms include the proliferation of lymphocytes T helper 1 and T helper 17 and their impact on the periodontium, the dysfunction of vascular endothelium in gingival microcirculation and the influence of hypothyroidism on bone metabolism, namely on the alveolar bone. There is biological plausibility to support the establishment of an association between Hashimoto's thyroiditis and periodontal disease. However, there are not enough studies to support the existence of a causal nexus between these two pathologies, so, in the future, more studies should be conducted to determinate there relation and interaction.

    Full Text Available Objective: Periodontal diseases have a high prevalence worldwide. Existing evidence support the concept that gingivitis and periodontitis are potentially infectious and they present inflammatory reservoirs that can be threatening to the fetoplacental unit. The objective of this study was to compare the periodontal status between women with normal delivery and those with preterm low-birthweight delivery. Materials and Methods: This study included 200 postpartum women whose periodontal and obstetrical parameters were taken. The periodontal condition was assessed bedside according to the modified criteria established by Machtei, while the birthweight and gestational age were assessed according to the World Health Organization criteria. Results: Women with periodontitis are statistically at 3.2 times higher risk to deliver a child with low weight, and at 3.4 times higher risk to deliver preterm, compared to women without periodontitis. The women with preterm low-birthweight babies had deeper periodontal pockets (2.49mm ± 0.49mm than women with normal delivery (2.26mm ± 0.49mm. Conclusions: Periodontal disease in pregnant women with a reservoir of organisms and their products can be considered a risk factor for adverse pregnancy outcome.

    Thirty-two client-owned dogs treated for periodontal disease were divided in group 1 if no periodontitis, group 2 if ≤25%, and group 3 if >25% of the teeth present were affected with periodontitis. Blood was tested before and 2 weeks after periodontal therapy for nitrosyl hemoglobin (HbNO), plasma nitrite/nitrate (NOx) and 3-nitrotyrosine (NT) levels. No HbNO was detected in any of the animals tested. There was no significant difference in the NOx plasma levels within each group or across the groups before and after the treatment, but a noticeable increase in NOx plasma levels was observed in group 3 after the treatment. Plasma NT was detected in only one third of the animals. NO levels varied greatly across individual dogs. The data are suggestive of an overall increase in systemic NO response 2 weeks after periodontal treatment in dogs with advanced periodontal disease, but the response is greatly individually-dependent.

    To explore the clinical characteristics of IgA nephropathy (IgAN) with severe chronic periodontitis and aggressive periodontitis. A total of 436 hospitalized patients who underwent renal needle biopsy in the department of nephrology of China-Japan Friendship Hospital from November 2013 to December 2014 were recruited in the study and blindly had periodontal examination. The patients were divided into IgAN group and non-IgAN group according to the renal pathology. The patients with IgAN were further categorized as non-periodontitis, chronic periodontitis and aggressive peridontitis group by Haas classification. The chronic periodontitis group was continually divided into mild, moderate and severe periodontitis group. The levels of interleukin (IL)-1β and IL-6 in gingival crevicular fluid were analyzed by enzyme-linked immunosorbent assays. The prevalence of periodontitis in the study was 88.3% (385/436).

    The purpose of this study was to identify factors promoting formation of the cemento-periodontal ligament junction. Regeneration of the cemento-periodontal ligament junction is an important factor in recovery of the connective tissue attachment to the cementum and it is important to identify all specific substances that promote its formation. To clarify the substances involved in cemento-periodontal ligament junction formation, we produced a monoclonal antibody (mAb) to human cemento-periodontal ligament junction (designated as the anti-TAP mAb) and examined its immunostaining properties and reactive antigen. Hybridomas producing monoclonal antibody against human cemento-periodontal ligament junction antigens were established by fusing P3U1 mouse myeloma cells with spleen cells from BALB/c mice immunized with homogenized human cemento-periodontal ligament junction. The mAb, the anti-TAP mAb for cemento-periodontal ligament junction, was then isolated. The immunoglobulin class and light chain of the mAb were examined using an isotyping kit. Before immunostaining, antigen determination using an enzymatic method or heating was conducted. Human teeth, hard tissue-forming lesions, and animal tissues were immunostained by the anti-TAP mAb. The anti-TAP mAb was positive in human cemento-periodontal ligament junction and predentin but negative in all other human and animal tissues examined. In the cemento-osseous lesions, the anti-TAP mAb was positive in the peripheral area of the cementum and cementum-like hard tissues and not in the bone and bone-like tissues. The anti-TAP mAb showed IgM (kappa) and recognized phosphoprotein. The anti-TAP mAb is potentially useful for developing new agents promoting cementogenesis and periodontal regeneration.

    2013-01-01

    In comparison to non-Hispanic whites, a number of health-care disparities, including poor oral health, have been identified among Hispanics in general and Mexican Americans in particular. We hypothesized that Mexican Americans with chronic kidney disease (CKD) would have higher prevalence of chronic periodontitis compared with Mexican Americans with normal kidney function, and that the level of kidney function would be inversely related to the prevalence of periodontal disease. We examined this hypothesis using the National Health and Nutrition Examination Survey 1988-1994 (NHANES III) data set. We followed the American Academy of Periodontology/Center for Disease Control and Prevention case definition for periodontitis. Glomerular filtration rate was estimated using the CKD-Epidemiology equation for Hispanic populations. The classification to CKD stages was based on the National Kidney Foundation Kidney Disease Outcomes Quality Initiative. Periodontitis prevalence increased across the kidney function groups showing a statistically significant dose-response association (Pperiodontitis compared with Mexican Americans with normal kidney function after adjusting for potential confounders such as smoking, diabetes, and socioeconomic status. Multivariate adjusted odds ratio for periodontitis significantly increased with 1, 5, and 10 mL/minute estimated glomerular filtration rate reduction from the mean. This is the first report, to the best our knowledge, that showed an increase of periodontitis prevalence with decreased kidney function in this population. © 2012 American Association of Public Health Dentistry.

    Full Text Available The objectives of this cross-sectional study were: 1 to estimate the prevalence and characterize the severity of periodontal disease in a population of dogs housed in commercial breeding facilities; 2 to characterize PD preventive care utilized by facility owners; and 3 to assess inter-rater reliability of a visual scoring assessment tool. Adult dogs (N = 445 representing 42 breeds at 24 CB facilities in Indiana and Illinois were assessed. Periodontal disease was scored visually using the American Veterinary Dental Collage 0-IV scale. Inter-rater reliability was assessed on 198 dogs and facility owners were asked to provide information about the preventive care utilized. The overall prevalence of periodontal disease (Grades I-IV was 86.3% (95% CI: 82.9, 89.3. An ordered logistic regression analysis found age (OR = 1.4; 95% CI 1.24, 1.54; P<0.0001, facility (OR = 1.13; 95% CI 1.09, 1.18; P<0.0001, sex (OR = 1.7; 95% CI 1.12, 2.65; P = 0.013, and non-professional dental scaling (OR = 2.82; 95% CI 1.34, 5.91; P = 0.006 to be statistically significant. Inter-rater reliability analysis found agreement to be 86.2%, with a weighted kappa of 0.4731 (95% CI 0.3847, 0.5615 indicating moderate agreement. Risk of periodontal disease increased with increasing age. Additionally, a trend toward decreasing risk with increasing weight was also found, although it was not statistically significant. The trends identified agree with studies that have evaluated periodontal disease in the companion dog population and do not support the assumption that the dental health of dogs in commercial breeding facilities is worse than that of the population as a whole. Although there were few cases of severe periodontal disease and all facilities employed some type of preventive care in this sample, the large number of dogs with some degree of disease (Grades I-IV suggests that further investigation of preventive care is warranted.

    Dimensions of periodontal tissues are thought to predispose to the development of periodontal disease in man and dogs. Several studies have suggested that thin gingiva correlates with an increased incidence of periodontal disease. In this study, we hypothesized that the dimensions of periodontal tissues will vary in different breeds of dogs and could possibly correlate with the incidence of periodontal disease. Forty-two jaws of dogs aged up to 5-years were examined post-mortem and gingival and alveolar bone thickness were measured using methods of transgingival probing and digital calipers, respectively. Dogs were divided into three groups based on their body weight. Group I (dogs compared with small and medium-sized breed dogs. Both gingival and alveolar bone dimensions may be predictors for severity of periodontal disease and influence clinical outcome in certain periodontal surgical procedures.

    Accumulated lines of evidence suggest that hyperimmune responses to periodontal bacteria result in the destruction of periodontal connective tissue and alveolar bone. The etiological roles of periodontal bacteria in the onset and progression of periodontal disease (PD) are well documented. However, the mechanism underlying the engagement of periodontal bacteria in RANKL-mediated alveolar bone resorption remains unclear. Therefore, this review article addresses three critical subjects. First, we discuss earlier studies of immune intervention, ultimately leading to the identification of bacteria-reactive lymphocytes as the cellular source of osteoclast-induction factor lymphokine (now called RANKL) in the context of periodontal bone resorption. Next, we consider (1) the effects of periodontal bacteria on RANKL production from a variety of adaptive immune effector cells, as well as fibroblasts, in inflamed periodontal tissue and (2) the bifunctional roles (upregulation vs. downregulation) of LPS produced from periodontal bacteria in a RANKL-induced osteoclast-signal pathway. Future studies in these two areas could lead to new therapeutic approaches for the management of PD by down-modulating RANKL production and/or RANKL-mediated osteoclastogenesis in the context of host immune responses against periodontal pathogenic bacteria.

    Accumulated lines of evidence suggest that hyperimmune responses to periodontal bacteria result in the destruction of periodontal connective tissue and alveolar bone. The etiological roles of periodontal bacteria in the onset and progression of periodontal disease (PD) are well documented. However, the mechanism underlying the engagement of periodontal bacteria in RANKL-mediated alveolar bone resorption remains unclear. Therefore, this review article addresses three critical subjects.

    ABSTRACT Periodontal disease ranges from gingival inflammation (gingivitis) to the inflammation and loss of tooth-supporting tissues (periodontitis). Previous research has focused mainly on subgingival plaque, but supragingival plaque composition is also known to be associated with disease. Quantitative modeling of bacterial abundances across the natural range of periodontal severities can distinguish which features of disease are associated with particular changes in composition. We assessed a cross-sectional cohort of 962 Malawian women for periodontal disease and used 16S rRNA gene amplicon sequencing (V5 to V7 region) to characterize the bacterial compositions of supragingival plaque samples. Associations between bacterial relative abundances and gingivitis/periodontitis were investigated by using negative binomial models, adjusting for epidemiological factors. We also examined bacterial cooccurrence networks to assess community structure. The main differences in supragingival plaque compositions were associated more with gingivitis than periodontitis, including higher bacterial diversity and a greater abundance of particular species. However, even after controlling for gingivitis, the presence of subgingival periodontitis was associated with an altered supragingival plaque. A small number of species were associated with periodontitis but not gingivitis, including members of Prevotella, Treponema, and Selenomonas, supporting a more complex disease model than a linear progression following gingivitis. Cooccurrence networks of periodontitis-associated taxa clustered according to periodontitis across all gingivitis severities. Species including Filifactor alocis and Fusobacterium nucleatum were central to this network, which supports their role in the coaggregation of periodontal biofilms during disease progression. Our findings confirm that periodontitis cannot be considered simply an advanced stage of gingivitis even when only considering supragingival plaque

    Current periodontal disease taxonomies have limited utility for predicting disease progression and tooth loss; in fact, tooth loss itself can undermine precise person-level periodontal disease classifications. To overcome this limitation, the current group recently introduced a novel patient stratification system using latent class analyses of clinical parameters, including patterns of missing teeth. This investigation sought to determine the clinical utility of the Periodontal Profile Classes and Tooth Profile Classes (PPC/TPC) taxonomy for risk assessment, specifically for predicting periodontal disease progression and incident tooth loss. The analytic sample comprised 4,682 adult participants of two prospective cohort studies (Dental Atherosclerosis Risk in Communities Study and Piedmont Dental Study) with information on periodontal disease progression and incident tooth loss. The PPC/TPC taxonomy includes seven distinct PPCs (person-level disease pattern and severity) and seven TPCs (tooth-level disease). Logistic regression modeling was used to estimate relative risks (RR) and 95% confidence intervals (CI) for the association of these latent classes with disease progression and incident tooth loss, adjusting for examination center, race, sex, age, diabetes, and smoking. To obtain personalized outcome propensities, risk estimates associated with each participant's PPC and TPC were combined into person-level composite risk scores (Index of Periodontal Risk [IPR]). Individuals in two PPCs (PPC-G: Severe Disease and PPC-D: Tooth Loss) had the highest tooth loss risk (RR = 3.6; 95% CI = 2.6 to 5.0 and RR = 3.8; 95% CI = 2.9 to 5.1, respectively). PPC-G also had the highest risk for periodontitis progression (RR = 5.7; 95% CI = 2.2 to 14.7). Personalized IPR scores were positively associated with both periodontitis progression and tooth loss. These findings, upon additional validation, suggest that the periodontal/tooth profile classes and the derived

    Frame Partial Denture as a Supportive Therapy for Periodontal Health. Partial denture is very important in maintaining periodontal health and maintaining the stability of the remaining teeth. The fabrication of denture is an important phase in comprehensive periodontal health therapy, so as to maintain the periodontal health. Removable partial dentures should be designed to reduce the accumulation of food residue and plaque on the teeth and gingival edge of the abutment. The selection of metallic materials as denture in case of periodontal compromise can help in preventing tooth movement and maintain the position of the teeth after periodontal treatment because the nature of metal is more rigid when compared with other materials, so that the success of the treatment can be achieved. Making good metal framework denture and good cooperation between all members of the medical team in handling the case will result in a successful treatment. The aim of the study is to enrich the knowledge for periodontists and prosthodontists in using metal removable prothesis in compromised periodontal patients. Providing information and educating patients in maintaining the cleanliness of denture and mouth are also an important factor that determines the success of the manufacture of dentures.

    The effectiveness of maintenance care program applied at different period of time was evaluate in patients treated for gingivitis and incipiente marginal periodontitis. Fifty six patients were divided in three groups, each one controlled three times (each 2, 4 and 6 months respectively), to evaluate periodontal health. At each control, gingival index and plaque index was registered and patients had profilaxis and reinforcement of dental care instructions. All patients knew and practiced a control plaque control during active treatment. Results demonstrated that maintenance care program applied each 2 months, could get better clinical healthy periodontal conditions, without influence of patient's control plaque. Those patients with good hygiene could provide for an acceptable level of periodontal health even in patients controlled each 4 and 6 months. Positive correlations between controls in each index are indicative for that. Age seemingly do not have influence like etiological factor of recurrence inflammation. High correlation between plaque index and gingival index was found in every control mainly in the groups controlled each 4 and 6 months.

    Periodontal diseases are among the most prevalent oral diseases in the world. Apart from repercussions in the oral cavity, there is evidence that periodontitis contributes to systemic damage in chronic diseases such as cardiovascular disease, diabetes, and preterm low birth weight. The aims of this study were to estimate the prevalence of chronic periodontitis in a sample urban population (<18 years) in Tamil Nadu and to estimate the inflammatory burden posed by chronic periodontitis by calculating the periodontal inflammatory surface area. This was a population-based study and cross-sectional design. A total of 1000 individuals (<18 years) were selected and screened for their periodontal status, oral hygiene status (OHI), and the periodontal inflamed surface area (PISA) in an outreach center located in Chennai, India. The proportion of individuals with different periodontal states (health, gingivitis, and periodontitis) was determined. A multivariate logistic regression analysis was performed to assess the influence of the individual risk factors such as habits (tobacco use), systemic conditions (diabetes), and oral hygiene maintenance on periodontitis prevalence in the sample population. A high prevalence of periodontal disease was observed in the study population (42.3%). Among the urban participants, age, cigarette smoking, pan chewing, decayed, missing, and filled teeth scores, OHI scores, and PISA scores were found to be significantly associated with periodontitis (P < 0.05). Periodontitis prevalence appears to be high even in areas with adequate access to oral health care and an inflammatory burden risk exists in a definitive manner.

    Full Text Available Objectives. To evaluate the impact of chronic periodontal diseases (PDs and compare phases of nonsurgical periodontal therapy (NSPT on oral health-related quality of life (OHRQoL in patients attending a tertiary care center of eastern Nepal. Materials and Methods. Matched for socioeconomic status, participants were recruited in two groups: moderate-to-severe chronic periodontitis (n=24, 43±46 years and chronic gingivitis (n=25, 30±96 years. The treatment modalities were scaling and root surface debridement (RSD and supragingival scaling, respectively. The impact of periodontal disease treatment status was assessed by a self-reported questionnaire of Nepali Oral Health Impact Profile (OHIP-14 at baseline and 9–12 weeks after NSPT. Results. The median (IQR OHIP-14 total scores for PDs reduced from 7 (3–11 to 3 (1–7.5 after NSPT. Both groups showed a significant improvement on OHRQoL (p value < 0.001. The periodontitis group showed an increased median (IQR reduction of 52% (35.22–86.15 compared with the gingivitis group with 27% (0.00–50.00. The impact on orofacial pain, orofacial appearance, and psychosocial dimensions was observed, which improved after NSPT in both groups. Conclusion. PDs are directly associated with OHRQoL and treatment of the disease may enhance quality of life from a patient’s perspective. Scaling and RSD provided better influence on OHRQoL than supragingival scaling.

    There is a deep relationship between cardiovascular disease and periodontitis. It has been reported that myocardial hypertrophy may be affected by periodontitis in clinical settings. Although these clinical observations had some study limitations, they strongly suggest a direct association between severity of periodontitis and left ventricular hypertrophy. However, the detailed mechanisms between myocardial hypertrophy and periodontitis have not yet been elucidated. Recently, we demonstrated that periodontal bacteria infection is closely related to myocardial hypertrophy. In murine transverse aortic constriction models, a periodontal pathogen, Aggregatibacter actinomycetemcomitans markedly enhanced cardiac hypertrophy with matrix metalloproteinase-2 activation, while another pathogen Porphyromonas gingivalis (P.g.) did not accelerate these pathological changes. In the isoproterenol-induced myocardial hypertrophy model, P.g. induced myocardial hypertrophy through Toll-like receptor-2 signaling. From our results and other reports, regulation of chronic inflammation induced by periodontitis may have a key role in the treatment of myocardial hypertrophy. In this article, we review the pathophysiological mechanism between myocardial hypertrophy and periodontitis.

A total of 443 participants with a mean age of 44.3 (±6.5) participated in the study from April 2011 to December 2011. Males comprised 64.7%, and females comprised 35.2%. Participants were interviewed on social demographics and oral habits. Participants with shallow pockets (3.5-5.5 mm) and deep pockets (greater than 5.5 mm) were considered suffering from chronic periodontitis. The characteristics of participants were assessed using frequency distribution for categorical variables and mean (standard deviation) for continuous variables.  Among 443 participants, smokers were distributed as 55.1% and non-smokers as 44.9%. Smoking was found to be significantly related to young adults (p less than 0.007), male gender (p less than 0.001), and lower education level (p less than 0.01). Overall prevalence of chronic periodontitis among smokers was estimated at 81.6%. Heavy smoking was found to have significantly high prevalence (p less than 0.001) and severity (p less than 0.001) of periodontitis as compared with moderate and light smokers. The multivariate unadjusted model depicted 3.5 times higher risk of chronic periodontitis among smokers (p less than 0.001). Chronic periodontitis had a high prevalence among smokers. Heavy smoking was found to have a higher risk for having periodontitis.

    Periodontitis is an inflammatory condition that affects the supporting tissues surrounding teeth. The occurrence of periodontitis is associated with shifts in the structure of the communities that inhabit the gingival sulcus. Although great inter-subject variability in the subgingival microbiome has been observed in subjects with periodontitis, it is unclear whether distinct community types exist and if differences in microbial signatures correlate with host characteristics or with the variable clinical presentations of periodontitis. Therefore, in this study we explored the existence of different community types in periodontitis and their relationship with host demographic, medical and disease-related clinical characteristics. Clustering analyses of microbial abundance profiles suggested two types of communities (A and B) existed in the 34 subjects with periodontitis evaluated. Type B communities harbored greater proportions of certain periodontitis-associated taxa, including species historically associated with the disease, such as Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola, and taxa recently linked to periodontitis. In contrast, subjects with type A communities had increased proportions of different periodontitis-associated species, and were also enriched for health-associated species and core taxa (those equally prevalent in health and periodontitis). Periodontitis subgingival clusters were not associated with demographic, medical or disease-specific clinical parameters other than periodontitis extent (proportion of sites affected), which positively correlated with the total proportion of cluster B signature taxa. In conclusion, two types of microbial communities were detected in subjects with periodontitis. Host demographics and underlying medical conditions did not correlate with these profiles, which instead appeared to be related to periodontitis extent, with type B communities present in more widespread disease cases. The two

    Periodontal diseases, considered as inflammatory diseases have proved to have a spectrum of systemic implications. Earliest research has associated periodontal disease with common systemic aliments such as hypertension, diabetes, osteoporosis, rheumatoid arthritis to name a few. The evolution of advanced diagnostic aids let researchers make vast inroads in linking periodontal diseases to systemic diseases like Alzheimer's disease (AD) and even Schizophrenia. Our aim was to review and critically evaluate comprehensive literature and provide knowledge to medical practitioners on these associations so as to pave way for closer interactions between medical and dental practitioners in implementing better health care. Electronic databases such as PubMed, Google Scholar and Cochrane databases were used as source of the data for relevant studies published from 2005 up to 2015 with the following keywords, "'Periodontal disease", "systemic conditions", "periodontal disease and Alzheimer's", "Periodontal disease and Schizophrenia", "Periodontal disease and Psoriasis" and "Periodontal disease and erectile dysfunction". The evidence presented ascertains that a reasonable and modest association does exist between Periodontal disease and Alzheimer's, Schizophrenia, Erectile dysfunction, as well as Psoriasis and thus establishes periodontal disease as a potential risk factor.

    Orthodontic treatment aims at providing an acceptable functional and aesthetic occlusion with appropriate tooth movements. These movements are strongly related to interactions of teeth with their supportive periodontal tissues. In recent years, because of the increased number of adult patients seeking orthodontic treatment, orthodontists frequently face patients with periodontal problems. Aesthetic considerations, like uneven gingival margins or functional problems resulting from inflammatory periodontal diseases should be considered in orthodontic treatment planning. Furthermore, in cases with severe periodontitis, orthodontics may improve the possibilities of saving and restoring a deteriorated dentition. In modern clinical practice, the contribution of the orthodontist, the periodontist and the general dentist is essential for optimized treatment outcomes. The purpose of this systematic review is to highlight the relationship between orthodontics and periodontics in clinical practice and to improve the level of cooperation between dental practitioners. Potentials and limitations that derive from the interdisciplinary approach of complex orthodontic-periodontal clinical problems are discussed.

    Periodontal disease may increase the risk of adverse birth outcomes; however, results have been mixed. Few studies have examined periodontal disease in developing countries. We describe the relationship between periodontal disease and birth outcomes in a community setting in Pakistan. This was a prospective cohort study. Enrollment occurred at 20-26 weeks of gestation. A study dentist performed the periodontal examination to assess probing depth, clinical attachment level, gingival index, and plaque index. Outcomes included stillbirth, neonatal death, perinatal death, increasing periodontal disease severity by quartiles. Dental examinations and outcome data were completed for 1152 women: 81% of the women were multiparous, with a mean age of 27 years; 33% of the women had no education. Forty-seven percent of the women had dental caries; 27% of the women had missing teeth, and 91% of the women had had no dental care in the last year. Periodontal disease was common: 76% of the women had > or = 3 teeth with a probing depth of > or = 3 mm; 87% of the women had > or = 4 teeth with a clinical attachment level of > or = 3 mm; 56% of the women had > or = 4 teeth with a plaque index of 3; and 60% of the women had > or = 4 teeth with a gingival index of 3. As the measures of periodontal disease increased from the 1st to 4th quartile, stillbirth and neonatal and perinatal death also increased, with relative risks of approximately 1.3. Early preterm birth increased, but the results were not significant. Late preterm birth and low birthweight were not related to measures of periodontal disease. Pregnant Pakistani women have high levels of moderate-to-severe dental disease. Stillbirth and neonatal and perinatal deaths increased with the severity of periodontal disease.

    Endodontic and periodontal microsurgery has surpassed the success rates for traditional endodontic and periodontal surgical procedures. Excellent healing results are being attributed to both the techniques, when employed, for isolated endodontic or periodontal defects. Combined endodontic-periodontal lesions have been referred to as a true challenge, requiring not only endodontic microsurgical management but also concurrent bone grafting and membrane barriers techniques. The prevention of epithelial downgrowth and regeneration of periodontal cementum, fiber, and bone seals the fate of these cases. Achieving primary closure with submergence of grafts has a positive effect on GTR outcome. New techniques of periodontal microsurgery, such as minimally invasive papilla preserving flaps with passive internal mattress suturing, have managed to obtain 90% primary flap closure over grafted sites. Root surface treatment and conditioning has also shown to be beneficial for GTR. Endodontic microsurgery for the combined lesion has not integrated these advances yet. These advances, along with a recently suggested treatment strategy, are ushering in the level next in management of the combined lesions. This article offers an overview of the combined lesion, the disease, its classification, treatment strategy, regenerative tools, microsurgical recommendations, and outcome studies.

    Full Text Available Periodontal disease when occurring in children leads to premature tooth loss, affecting the quality of life. Thus, screening pediatric and adolescent patients early, for periodontal disease is deemed imperative to its early management for improved prognosis. Chronic periodontitis (CP has slow rate of progression, whereas aggressive periodontitis (AP affecting children and young adults has rapid rate of progression. The management of AP in particular is affected by bacterial virulence of Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis in plaque leading to rapid attachment and bone loss around the affected teeth. Nonsurgical treatment, use of appropriate antimicrobial therapy, and surgical correction of defects is required to mitigate disease followed by a comprehensive supportive periodontal therapy. This review visits the current understanding of periodontal disease, its management in pediatric and adolescent patients.

    Full Text Available Abstract Introduction Prader-Willi syndrome is a complex genetic disease caused by lack of expression of paternally inherited genes on chromosome 15q11-q13. The prevalence of Prader-Willi syndrome is estimated to be one in 10,000 to 25,000. However, descriptions of the oral and dental phenotype are rare. Case presentation We describe the clinical presentation and periodontal findings in a 20-year-old Japanese man with previously diagnosed Prader-Willi syndrome. Clinical and radiographic findings confirmed the diagnosis of periodontitis. The most striking oral findings were anterior open bite, and crowding and attrition of the lower first molars. Periodontal treatment consisted of tooth-brushing instruction and scaling. Home care involved recommended use of adjunctive chlorhexidine gel for tooth brushing twice a week and chlorhexidine mouthwash twice daily. Gingival swelling improved, but further treatment will be required and our patient's oral hygiene remains poor. The present treatment of tooth-brushing instruction and scaling every three weeks therefore only represents a temporary solution. Conclusions Rather than being a direct result of genetic defects, periodontal diseases in Prader-Willi syndrome may largely result from a loss of cuspid guidance leading to traumatic occlusion, which in turn leads to the development of periodontal diseases and dental plaque because of poor oral hygiene. These could be avoided by early interventions to improve occlusion and regular follow-up to monitor oral hygiene. This report emphasizes the importance of long-term follow-up of oral health care by dental practitioners, especially pediatric dentists, to prevent periodontal disease and dental caries in patients with Prader-Willi syndrome, who appear to have problems maintaining their own oral health.

    Type I plasminogen deficiency (Plgdef) is an uncommon chronic inflammation of mucous membranes. Gingival enlargements usually proceed with progressive periodontal destruction and tooth-loss. Plasmin(ogen)-independent enzymatic mechanisms for fibrin clearance have already been discussed in the literature. Our primary objective was to verify, immunohistochemically, the occurrence of different enzymatic factors involved in tissue breakdown of inflamed compared to healthy gingiva. Secondly, we tried to find out, if these patients have a similar microbiological profile to the patients with known gingivitis and periodontitis. Immunohistochemical analysis of enzymes elastase, plasminogen (plg), cathepsin G, matrix-metalloproteinase (MMP)-3 and MMP-7 and of glycoprotein fibrinogen were performed with gingival tissues from 3 healthy controls, 8 patients with Plgdef and 3 patients with gingivitis and periodontitis. Furthermore, plaque from 5 patients with plasminogen deficiency were also obtained to determine the microbiological profile. Significantly high numbers of elastase positive leukocytes were detected in all samples. Staining for MMP-3 and MMP-7 was seen in samples with gingivitis and periodontitis with a stronger staining in samples with periodontitis by Plgdef. Fibrinogen was detectable in all samples. Staining for plg was stronger in samples with periodontitis than in other samples. Staining for cathepsin G was weak in gingivitis and periodontitis. Subgingival microbial flora showed elevated colony forming units of Prevotella intermedia/nigrescens, Fusobacterium spp., Eikenella corrodens, Porphyromonas gingivalis and viridans streptococci. Strong staining of elastase, MMP-3 and MMP-7 and weak staining of plg in Plgdef samples supports the plasmin(ogen) - independent fibrin clearance. Similar subgingival microbiological flora was observed in periodontitis with Plgdef as in other periodontal diseases. Further investigations should determine the exact pathomechanism

    Gingival changes during pregnancy have been well-documented. The prevalence of gingivitis in pregnant women has reportedly ranged from 30% to 100%. Increase in both the rate of estrogen metabolism and synthesis of prostaglandins by the gingiva contributed to the gingival changes observed during pregnancy. In effect increased prevalence of dental caries, gingivitis, periodontitis and tooth mobility may be encountered in pregnancy. The purpose of the study was to determine the association of some variables and the periodontal status in a sample of pregnant women attending the Ante Natal Clinic (ANC) of Lagos State University Teaching Hospital (LASUTH), Ikeja, Lagos. Women at various stages of pregnancy, attending the ANC of LASUTH, constituted the target population. The questionnaire was administered on each patient followed by dental examinations. Periodontal status was assessed using the community periodontal index (CPI) of treatment needs. Oral hygiene status was evaluated according to Green and Vermilion simplified oral hygiene index (OHI-S). The association between the CPI scores; OHI-S scores and variables such as trimester and dental visits were statistically significant. This study indicated that the gestational age of pregnancy and dental visits have a definite impact on the periodontal status. Oral health education should be included as an integral part of antenatal care to increase the women awareness. This would improve the mothers' dental care-seeking behavior.

    Treatment protocols with low-level Laser (also called ‘soft laser therapy) have been used in health care systems for more than three decades. Bearing in mind the suitable sub-cellular absorption and the cellular-vascular impacts, low-level laser may be a treatment of choice for soft tissues. Low-level lasers have played crucial and colorful roles in performing periodontal surgeries. Their anti-inflammatory and painless effects have been variously reported in in-vitro studies. In this present review article, searches have been made in Pub Med, Google Scholar, and Science Direct, focusing on the studies which included low-level lasers, flap-periodontal surgeries, gingivectomy, and periodontal graft. The present study has sought to review the cellular impacts of low-level lasers and its role on reducing pain and inflammation following soft tissue surgical treatments. PMID:25987968

    Full Text Available ABSTRACT Periodontal disease has been associated with elevations of blood cytokines involved in atherosclerosis in systemically healthy individuals, but little is known about this association in stable cardiovascular patients. The aim of this study was to assess the association between periodontal disease (exposure and blood cytokine levels (outcomes in a target population of patients with stable coronary artery disease (CAD. Material and Methods This cross-sectional study included 91 patients with stable CAD who had been under optimized cardiovascular care. Blood levels of IL-1β, IL-6, IL-8, IL-10, IFN-γ, and TNF-α were measured by Luminex technology. A full-mouth periodontal examination was conducted to record probing depth (PD and clinical attachment (CA loss. Multiple linear regression models, adjusting for gender, body mass index, oral hypoglycemic drugs, smoking, and occurre:nce of acute myocardial infarction were applied. Results CAD patients that experienced major events had higher concentrations of IFN-γ (median: 5.05 pg/mL vs. 3.01 pg/mL; p=0.01, IL-10 (median: 2.33 pg/mL vs. 1.01 pg/mL; p=0.03, and TNF-α (median: 9.17 pg/mL vs. 7.47 pg/mL; p=0.02. Higher numbers of teeth with at least 6 mm of CA loss (R2=0.07 and PD (R2=0.06 were significantly associated with higher IFN-γ log concentrations. Mean CA loss (R2=0.05 and PD (R2=0.06 were significantly related to IL-10 concentrations. Elevated concentrations of TNF-α were associated with higher mean CA loss (R2=0.07. Conclusion Periodontal disease is associated with increased systemic inflammation in stable cardiovascular patients. These findings provide additional evidence supporting the idea that periodontal disease can be a prognostic factor in cardiovascular patients.

    Periodontal infection is a possible risk factor for respiratory disorders; however, no studies have assessed the colonization of periodontal pathogens in endotracheal tubes (ET). This case-control study analyzed whether periodontal pathogens are able to colonize ET of dentate and edentulous patients in intensive care units (ICU) and whether oral and ET periodontal pathogen profiles have any correlation between these patients. We selected 18 dentate and 18 edentulous patients from 78 eligible ICU patients. Oral clinical examination including probing depth, clinical attachment level, gingival index , and plaque index was performed by a single examiner, followed by oral and ET sampling and processing by quantitative polymerase chain reaction (total bacterial load, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Tannerella forsythia). Data were statistically analyzed by Mann-Whitney U, two-way analysis of variance (p Periodontal pathogens can colonize ET and the oral cavity of ICU patients. Periodontal pathogen profiles tend to be similar between dentate and edentulous ICU patients. In ICU patients, oral cavity represents a source of ET contamination. Although accompanied by higher oral bacterial levels, teeth do not seem to influence ET bacterial profiles.

    We aimed to investigate the association between long working hours and periodontitis, and whether such an association constitutes an exposure-response relationship. Data for this study were collected from the Korea National Health and Nutrition Examination Surveys conducted from 2007 to 2014; 17,533 workers (9,483 of men and 8,050 of women) were included. The odds ratios (OR) and 95% confidence intervals (CI) for the analysis of periodontitis defined as positive of Community Periodontal Index in relation to working hours were calculated using multiple logistic regression models with various stratifications. Compared to participants who worked ≤40 hours per week, the prevalence ratio (95% CI) for the periodontitis was 1.19 (1.14-1.24) and full adjusted OR (95% CI) was 1.09 (1.02-1.18) in participants who worked over 40 hours per week. The OR (95% CI) for periodontitis were 1.09 (0.99-1.19) in working group of 40working group of >52 hours per week with a significant trend (p = 0.0233) even after adjusting for age, socioeconomic status, healthy behaviour, chronic disease, and dental care status. Long working hours are associated with periodontitis among Korean workers in an exposure-response manner.

    2015-06-01

    Full Text Available Periodontal diseases usually refer to common inflammatory disorders known as gingivitis and periodontitis, which are caused by a pathogenic microbiota in the subgingival biofilm, including Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Tannerella forsythia and Treponema denticola that trigger innate, inflammatory, and adaptive immune responses. These processes result in the destruction of the tissues surrounding and supporting the teeth, and eventually in tissue, bone and finally, tooth loss. The innate immune response constitutes a homeostatic system, which is the first line of defense, and is able to recognize invading microorganisms as non-self, triggering immune responses to eliminate them. In addition to the innate immunity, adaptive immunity cells and characteristic cytokines have been described as important players in the periodontal disease pathogenesis scenario, with a special attention to CD4+ T-cells (T-helper cells. Interestingly, the T cell-mediated adaptive immunity development is highly dependent on innate immunity-associated antigen presenting cells, which after antigen capture undergo into a maturation process and migrate towards the lymph nodes, where they produce distinct patterns of cytokines that will contribute to the subsequent polarization and activation of specific T CD4+ lymphocytes. Skeletal homeostasis depends on a dynamic balance between the activities of the bone-forming osteoblasts (OBLs and bone-resorbing osteoclasts (OCLs. This balance is tightly controlled by various regulatory systems, such as the endocrine system, and is influenced by the immune system, an osteoimmunological regulation depending on lymphocyte- and macrophage-derived cytokines.

    Periodontal disease has been associated with an increased risk of cardiovascular events. The purpose of our study was to investigate whether a correlation between periodontitis and chronic heart failure exists, as well as the nature of the underlying cause. We enrolled 71 patients (mean age, 54 ± 13 yr; 56 men) who had stable chronic heart failure; all underwent complete cardiologic and dental evaluations. The periodontal screening index was used to quantify the degree of periodontal disease. We compared the findings to those in the general population with use of data from the 4th German Dental Health Survey. Gingivitis, moderate periodontitis, and severe periodontitis were present in 17 (24%), 17 (24%), and 37 (52%) patients, respectively. Severe periodontitis was more prevalent among chronic heart failure patients than in the general population. In contrast, moderate periodontitis was more prevalent in the general population (P periodontal disease was not associated with the cause of chronic heart failure or the severity of heart failure symptoms. Six-minute walking distance was the only independent predictor of severe periodontitis. Periodontal disease is highly prevalent in chronic heart failure patients regardless of the cause of heart failure. Prospective trials are warranted to clarify the causal relationship between both diseases.

    Full Text Available Periodontitis is an infectious disease concerning supporting tissues of the teeth. The primary etiological agent for disease development and progression is the subgingival biofilm, but recently it is known that host factors may modify the pathological process or may affect the severity and /or extent. The increasing levels of some specific pathogenic subgingival bacteria such as Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, Fusobacterium nucleatum, Prevotella intermedia and others can result in periodontal destruction and possibly correlate with disease severity. Data from controlled studies show high prevalence of P. gingivalis, T. forsythia and Tr. denticola which represent the red complex (coexistence of these three species in patients with moderate and severe chronic periodontitis. Parallel investigation of probing depth (PD and clinical attachment level (CAL with the microbiological testing may give a confirmation of relation between subgingival pathogenic bacteria and severity of periodontitis.

    There is convincing evidence to suggest that infections affecting the mother during pregnancy may produce alterations in the normal cytokine- and hormone-regulated gestation, which could result in preterm labor, premature rupture of membranes, and preterm birth (PTB). Studies in the late 1990s associated periodontitis with preterm low birth weight (PLBW) deliveries, and this may have similar pathogenic mechanisms as other maternal infections. This study determined the effect of non-surgical periodontal therapy on pregnancy outcome. A total of 200 pregnant women with periodontitis were randomly assigned to treatment and control groups. Detailed data about previous and current pregnancies were obtained. All women received a full-mouth periodontal examination, including oral hygiene index-simplified, bleeding index, and clinical attachment level. The women in the treatment group received non-surgical periodontal therapy during the gestational period, and those in the control group received periodontal treatment after delivery. Periodontal therapy included plaque control instructions and scaling and root planing performed under local anesthesia. The outcome measures assessed were gestational age and birth weight of the infant. PTB was recorded when delivery occurred at PTBs in the treatment group and 68 PTBs in the control group. Twenty-six LBW infants were recorded in the treatment group, and 48 LBW infants were noted in the control group. The mean gestational ages were 33.8+/-2.8 weeks and 32.7+/-2.8 weeks in the treatment and control groups, respectively. The difference was statistically significant at P<0.006. The mean birth weight was 2,565.3+/-331.2 g in the treatment group and 2,459.6+/-380.7 g in the control group, with the difference being statistically significant at P<0.044. A multiple regression model showed a significant effect of periodontal treatment on birth outcomes. Non-surgical periodontal therapy can reduce the risk for preterm births in mothers who

    Full Text Available Objective: To identify the relationship between periodontitis in pregnant women through the periodontal disease index (PDI and low birth weight babies. Methods: A case-control study was conducted to determine the relationship between periodontitis in pregnant women through the periodontal disease index (PDI and the low birth weight babies (LBW. The participants were mothers with periodontitis and non-periodontitis mothers aged 20–35 years who gave birth in the Department of Obstetrics and Gynecology-Dr. Hasan Sadikin General Hospital, Bandung in the period of December to January 2005. Results: Based on the chisquare test results a highly significant relationship between periodontitis and low birth weight (p=0.002 was found. The Odd’s ratio showed that the risk of low birth weight in pregnant women with periodontitis was 15.58 times higher compared to those who did not suffer from periodontitis. The periodontal disease index has an accuracy of 88.6% in predicting the incidence of LBW. It strongly influenced the incidence of LBW with a high Odd’s ratio of 28.0. Pregnant women who suffer from periodontitis with a PDI > 3.25, have 19.2 times higher risk for delivering babies with LBW compared to the non-periodontitis mothers. Conclusions: The loss of attachment affects the possibility of delivering LBW babies.

    The aim of this study is to determine the relationship between atherosclerosis and periodontopathogenic microorganisms in chronic periodontitis patients following periodontal treatment. A total of 40 patients were included in the study. 20 of these patients diagnosed with atherosclerosis and chronic periodontitis formed the test group. The remaining 20 patients were systemically healthy patients diagnosed with chronic periodontitis and formed the control group. All patients had nonsurgical periodontal treatment. The periodontopathogenic microorganism levels were determined at baseline and at 6 months in microbial dental plaque samples and WBC, LDL, HDL, PLT, fibrinogen, creatinine and hs-CRP levels were determined by blood samples. Statistically significant reduction has been achieved in clinical periodontal parameters following non-surgical periodontal treatment in test and control groups. Following periodontal treatment, WBC, LDL, PLT, fibrinogen, creatinine and hs-CRP levels significantly decreased and HDL levels significantly increased in both test and control groups. Similarly, the periodontopathogenic microorganism levels significantly decreased following periodontal treatment in the test and control groups. A statistically significant positive correlation has been determined between the periodontopathogenic microorganism levels and WBC, LDL, PLT, fibrinogen, creatinine, and hs-CRP levels in the test group. The association between hs-CRP, WBC, LDL, PLT, fibrinogen, creatinine, and the amount of periodontopathogenic microorganisms indicates the possibility that periodontal treatment could decrease the risk atherosclerosis. More studies must be conducted in order for these results to be supported.

    Periodontal disease is one of the most common chronic infectious diseases. It has been reported that periodontal disease is associated with various adverse pregnancy outcomes including preterm birth, low birth weight, and gestational diabetes mellitus. Given the fact that the treatment for periodontal disease during pregnancy was ineffective in improving pregnancy outcomes by most of studies, the pre-conception period has been put forward as a more optimal time. However, very few studies have reported the prevalence of periodontal disease among pre-conception women. This study aimed to examine the prevalence and risk factors of periodontal disease among Chinese pre-conception women. A survey was conducted among pre-conception women at the Maternal and Child Health Hospital, Changzhou, China between January 2012 and December 2014. A total of 987 pre-conception women were recruited for a full-mouth dental examination after providing informed consent. A dental examination was carried out by probing six sites per tooth using a manual UNC-15 probe and a recording form. The overall rate of periodontal disease among participants was 73.9% (729/987) (95% confidence interval (CI): 71.0-76.6%). Among women with periodontal disease, 48.0% of cases were mild, 50.9% were moderate and 1.1% were severe. Self-reported bleeding during tooth brushing was the only significant predictive factor for overall periodontal disease (adjusted odds ratio (aOR): 3.71, 95% CI: 2.24, 6.15, P periodontal disease (aOR: 5.17, 95% CI: 3.05, 8.79, P periodontal disease was found in pre-conception Chinese women. Women who have bleeding during tooth brushing could be at increased risk of periodontal disease, and might require further oral health care.

    Full Text Available Reduction of the amount of tooth roots which are embedded in their periodontium could cause tooth mobility. Splinting a weaker tooth with a more stable one, and using the principle of the multiple-root stabilization is one way to overcome tooth mobility. Temporary splinting aims to prevent pathological migration, restore masticatory function, stabilize teeth before/after surgery, and evaluate the prognosis of periodontal treatment. The use of intracoronal splint is still controversial because there are only a few studies that have evaluated the effect of splinting on periodontal health. We report two cases to evaluate the effect of intracoronal splint on periodontal treatment. Two periodontal cases that use intracoronal splint before, during, and after periodontal regenerative therapy using bone graft. Causes of tooth mobility were removed and the splinting principles, terms and guidelines were mastered to get the maximum results of periodontal treatment. Both cases were evaluated radiographically 10 months after treatment. In these cases, intracoronal splint has supported the therapy before, during, or after surgery. Splinting is only for adjunctive therapy, and does not serve as the sole method in getting occlusal stability.DOI: 10.14693/jdi.v21i3.193

    Full Text Available Biomarkers are highly specific and sensitive indicators of disease activity. Resistin is a recently discovered adipocytokine, having a potent biomarker quality. Initially resistin was thought to be produced by adipocytes alone; however, emerging evidence suggests that it is also produced in abundance by various cells of the immunoinflammatory system, indicating its role in various chronic inflammatory diseases. Data suggests that resistin plays a role in obesity, insulin resistance, cardiovascular diseases, and periodontitis. Resistin derived its name from the original observation that it induced insulin resistance (resist-in: resist insulin in mice and is downregulated in mature murine adipocytes cultured in the presence of insulin sensitizing drugs like thiazolidinediones. It is well recognized that obesity, is associated with insulin resistance and diabetes. A three-way relationship has been established between diabetes, obesity and periodontitis. Recent evidence also suggests an association between obesity and increased risk for periodontitis. Our previous research showed incremental elevation of resistin with periodontal disease activity and a reduced level of resistin, after periodontal therapy. Thus resistin would be one of the molecular links connecting obesity, periodontitis, and diabetes and may serve as a marker that links periodontal disease with other systemic diseases. A Medline/PubMed search was carried out for keywords “Diabetes Mellitus,” “Periodontitis,” and “Resistin,” and all relevant research papers from 1990 in English were shortlisted and finalized based on their importance. This review provides an insight into the biological action of resistin and its possible role in periodontitis influenced diabetes mellitus and diabetes induced periodontitis.

    Inflammatory periodontal disease is a major cause of loss of tooth-supporting structures. Novel approaches for regeneration of periodontal apparatus is an area of intensive research. Periodontal tissue engineering implies the use of appropriate regenerative cells, delivered through a suitable scaffold, and guided through signaling molecules. Dental pulp stem cells have been used in an increasing number of studies in dental tissue engineering. Those cells show mesenchymal (stromal) stem cell-like properties including self-renewal and multilineage differentiation potentials, aside from their relative accessibility and pleasant handling properties. The purpose of this article is to review the biological principles of periodontal tissue engineering, along with the challenges facing the development of a consistent and clinically relevant tissue regeneration platform. This article includes an updated review on dental pulp stem cells and their applications in periodontal regeneration, in combination with different scaffolds and growth factors.

This study was aimed at analyzing the effect of non-surgical periodontal treatment on IL-29 levels in gingival crevicular fluid (GCF of chronic and aggressive periodontitis patients. A total of 60 participants were divided into healthy group (group 1; n = 20, chronic periodontitis group (group 2; n = 20, and aggressive periodontitis group (group 3; n = 20. GCF samples collected from each subject at baseline and 6–8 weeks after scaling and root planing were quantified for IL-29 levels using ELISA. The mean IL-29 concentration in GCF was found to be highest in group 3 (92.37 pg/μl. The mean IL-29 level in group 1 and group 2 was 36.88 pg/μl and 69.35 pg/μl respectively. After scaling and root planing, the mean concentration of IL-29 in GCF was increased to 85.99 pg/μl in group 2 and to 114.64 pg/μl in group 3. Results of the present study indicate that antiviral IL-29 level was highest in GCF of aggressive periodontitis patients and least in subjects with healthy periodontium, while that of chronic periodontitis lying in between. After non-surgical periodontal therapy, IL-29 levels increased both in chronic and aggressive periodontitis patients and deserve further investigation as a potential therapeutic agent in treating periodontitis.

    Naturally occurring periodontal disease affects >75% of dogs and has been associated with cardiac lesions and presumptive endocarditis. However, the relationships between periodontal disease and chronic kidney disease (CKD) in dogs have not been studied. In a retrospective longitudinal study the incidence of azotemic CKD was compared between a cohort of 164,706 dogs with periodontal disease and a cohort of age-matched dogs with no periodontal disease from a national primary care practice. These dogs contributed 415,971 dog-years of follow-up from 2002 to 2008. Hazard ratios and 95% confidence intervals from Cox regression were used to compare the incidence of azotemic CKD in dogs with stage 1, 2, or 3/4 periodontal disease to dogs with no periodontal disease. The hazard ratio for azotemic CKD increased with increasing severity of periodontal disease (stage 1 hazard ratio=1.8, 95% confidence interval: 1.6, 2.1; stage 2 hazard ratio=2.0, 95% confidence interval: 1.7, 2.3; stage 3/4 hazard ratio=2.7, 95% confidence interval: 2.3, 3.0; P(trend)=periodontal disease was also associated with serum creatinine >1.4 mg/dl and blood urea nitrogen >36 mg/dl, independent of a veterinarian's clinical diagnosis of CKD.

    An increasing number of studies are confirming an association between periodontal disease (PD) and adverse outcomes in pregnancy. PD places pregnant women at greater risk for preterm birth than alcohol consumption or smoking. This underscores the importance of offering dental screening to women who are pregnant or contemplating pregnancy and the need for physicians who provide obstetric care to be aware of the possible connection between poor dental health and poor pregnancy outcomes.

    The relationship between periodontal disease and dental pulp changes is controversial and has been debated for many years. This human study was performed to evaluate the possible effects of moderate to advanced periodontal disease on the different aspect of dental pulp structure. Twenty hopeless permanent teeth were extracted from systemically healthy adults because of moderate to advanced chronic periodontitis, with a bone loss of >6 mm and a mobility of grade 2 or 3. Upon extraction, the apical 2 to 3 mm of the roots were immediately sectioned. Four to five sections were mounted on each slide, and every third slide was stained with hematoxylin and eosin. The specimens were histologically processed and examined by an oral pathologist. Non-inflamed pulp, with partial or complete necrosis in some sections and several non-necrotic sections, was found in only 6.3% of teeth. Most teeth (58.3%) displayed edematous pulps. Slightly fibrotic pulps were seen in 52.1% of sections. Odontoblastic integrity was seen in 31.3% of teeth. Most teeth (77.1%) displayed no pulp stones. In 43.8% of teeth, the pulp vessels displayed dilatation. Moderate to advanced periodontal disease can affect the dental pulp. Careful consideration of diagnostic and treatment planing in patients with endodontic-periodontal involvement is therefore recommended.

    Studies conducted over the past 25 years have focused on the role of periodontitis, an inflammatory condition of microbial etiology that destroys the tooth supporting tissues, as a systemic inflammatory stressor that can act as an independent risk factor of atherosclerotic vascular disease (AVSD) and adverse pregnancy outcomes (APOs). It has been suggested that periodontitis-associated bacteremias and systemic dissemination of inflammatory mediators produced in the periodontal tissues may result in systemic inflammation and endothelial dysfunction, while bacteria of oral origin may translocate into the feto-placental unit. Epidemiologic studies largely support an association between periodontitis and ASVD / APOs independent of known confounders; indeed, periodontitis has been shown to confer statistically significantly elevated risk for clinical events associated with ASVD and APOs in multivariable adjustments. On the other hand, intervention studies demonstrate that although periodontal therapy reduces systemic inflammation and improves endothelial function, it has no positive effect on the incidence of APOs. Studies of the effects of periodontal interventions on ASVD-related clinical events are lacking. This review summarizes key findings from mechanistic, association and intervention studies and attempts to reconcile the seemingly contradictory evidence that originates from different lines of investigation.

    Adipokines enhance the synthesis of proinflammatory cytokines and matrix metalloproteinases (MMPs), which play a role in extracellular matrix degeneration. The aim of this study is to determine the levels of some adipokines, proinflammatory cytokines, and MMPs in the saliva of patients with periodontitis and healthy individuals and to evaluate the changes after non-surgical periodontal therapy (NSPT). Of 32 individuals included in the study, 17 had periodontitis and 15 had healthy gingiva. Saliva samples were obtained from all individuals. In patients with periodontitis, samples were recollected 3 and 6 months after NSPT. Visfatin, chemerin, progranulin, interleukin (IL)-1β, IL-8, MMP-8, and MMP-13 levels were measured using enzyme-linked immunosorbent assay. In patients with periodontitis, all of the parameters measured in the saliva were higher than those of healthy individuals. At 3 months, visfatin, progranulin, IL-8, and MMP-8 levels were significantly decreased compared with baseline values. The levels of other biochemical parameters, chemerin and IL-1β, were significantly decreased compared with baseline values at 6 months, and the levels became similar to those in healthy individuals. In the periodontitis group, positive correlations were found among visfatin and IL-8 (r = 0.909, P periodontal tissue in periodontitis by stimulating the expression of proinflammatory cytokines and MMPs.

    In recent years, evidence has come forth supporting the notion that localized infectious diseases such as periodontal disease may indeed influence a number of systemic diseases. Erectile dysfunction (ED) and chronic periodontitis have common risk factors such as diabetes mellitus, cardiac diseases and smoking etc. The aim was to evaluate the periodontal status of the subjects suffering from ED and to find association between vasculogenic ED and chronic periodontitis, if any. A total of 53 subjects suffering from vasculogenic ED were enrolled for the study and were divided into three groups on the basis of severity of ED. The clinical (probing pocket depth) and radiographic parameters (alveolar bone loss) were recorded and periodontal status of three groups was evaluated, compared and an attempt was made to find an association between ED and chronic periodontitis. Karl Pearson's correlation was used to assess an association between the two conditions. One-way ANOVA and Scheffe's test were used to find the significant difference of chronic periodontitis with severity of ED. Karl Pearson's correlation was used to find an association between chronic periodontitis and ED. Statistically significant mean differences of 1.73 mm, 0.56 mm and 1.17 mm were recorded when comparison was made among Group I and III, Group I and II and Group II and III, respectively. Mean differences in bone loss among three groups were also statistically significant. Both the diseases were positively correlated to each other. It may be concluded that chronic periodontitis and ED are associated with each other. However, further large scale studies with confounder analysis and longitudinal follow-up are warranted to explore the link between these two diseases.

    Severe periodontal disease is a chronic inflammatory gingival process associated with systemic diseases. To determine the prevalence of severe periodontal disease and its association with respiratory diseases among hospitalized patients at the Institute of Respiratory Diseases "Ismael Cosio Villegas" (INER) in 2011. A cross-sectional study was developed. The severe periodontal disease was diagnosed by the Department of Stomatology. The International Classification of Diseases 10th revision was used. A multinomial logistic was fit to estimate relative-risk. Three thousand and fifty-nine patients were included; 772/3,059 (25.2%) had severe periodontal disease. After controlling for age, sex, inpatient days, death, and socioeconomic status, the infectious respiratory diseases that were significantly associated with severe periodontal disease were: HIV/AIDS (RR: 10.6; 95% CI: 9.1-23.3; p abscess (RR: 2.6; 95% CI: 1.6-7.8; p = 0.002). Lung cancer and pleural diseases were also significantly associated with severe periodontal disease. High prevalence of severe periodontal disease was observed in the different respiratory diseases. Severe periodontal disease was associated with both infectious and non-infectious respiratory diseases. It is important to study an oral health intervention.

    2012-09-01

    This review aimed to update the current evidence on the efficacy of the adjunctive use of local and systemic antimicrobials in the treatment of periodontitis and to assess whether it might improve the clinical limitations and shortcomings of standard nonsurgical treatment in the management of periodontitis. Relevant randomized clinical trials (RCT) with more than 3 months of follow-up, published from 2010 to 2012 for systemic antimicrobials and from 2008 to 2012 for local antimicrobials, were searched in Medline and critically analyzed. Scientific evidence evaluated in different systematic reviews and reviews presented at European and World Workshops were also included. Only adjunctive therapies were considered in the present review: articles comparing debridement alone or plus placebo, versus debridement plus systemic or local antimicrobials were included. Adjunctive systemic antimicrobials have been evaluated both in aggressive and chronic periodontitis: in aggressive periodontitis, amoxicillin and metronidazole have been extensively studied, reporting clinical and microbiological benefits; in chronic periodontitis, different products are under scrutiny, such as azithromycin. The clinical efficacy of local antimicrobials, although extensively demonstrated, is still surrounded by a constant debate on the cost-effectiveness evaluation and on its adequate indications. Despite the clinical efficacy of the adjunctive use of local and systemic antimicrobials, demonstrated in RCTs and in systematic reviews, there is a lack of evidence to support well-defined clinical protocols, including products and dosages.

    Gingival and Periodontal diseases represent a major concern both in dentistry and medicine. The majority of the contributing factors and causes in the etiology of these diseases are reduced or treated with ozone in all its application forms (gas, water, oil). The beneficial biological effects of ozone, its anti-microbial activity, oxidation of bio-molecules precursors and microbial toxins implicated in periodontal diseases and its healing and tissue regeneration properties, make the use of ozone well indicated in all stages of gingival and periodontal diseases. The primary objective of this article is to provide a general review about the clinical applications of ozone in periodontics. The secondary objective is to summarize the available in vitro and in vivo studies in Periodontics in which ozone has been used. This objective would be of importance to future researchers in terms of what has been tried and what the potentials are for the clinical application of ozone in Periodontics.

    This 17.5-year longitudinal case report details the treatment of advanced chronic periodontitis in a female patient commencing at 34 years of age. The woman was provided with periodontal care comprising of temporary fixation, scaling and root planing, intra-pocket irrigation using a root canal syringe and regular supervised maintenance. The patient presented with a 10-year history of bleeding gums. Therapy conducted in general practice had included simple curettage and irrigation. However, these treatments proved unsuccessful and the patient often changed dentists seeking better treatment. She presented to the University Dental Hospital, for diagnosis and treatment of her periodontal conditions after her mandibular lateral incisor had exfoliated. On presentation a purulent exudate could be expressed from all of the pockets. All anterior teeth, excluding the maxillary canines, demonstrated +2 to +3 mobility. The patient did not want any surgical treatment or her teeth extracted. It was decided to treat the patient conservatively without surgery. By postponing extraction, the authors were in a better position to determine the prognosis of the remaining teeth after the infection was under control. Although six teeth were extracted during the 17.5 years, this case report suggests that a non-surgical approach is a viable option while maintaining regular visits for periodontal care.

    Background Dental caries and Periodontal diseases are the most prevalent oral health problems present globally. The distribution and severity of such oral health problems varies in different parts of the world and even in different regions of the same country. Nepal is one of the country with higher prevalence rate of these problems. These problems arise in association with multiple factors. Objective This study was carried out to describe the periodontal status and to analyse the association of periodontal disease with the wearing of fixed or removable partial dentures in a Nepalese population reporting to the College of Dental Surgery, B P Koirala Institute of Health Sciences, Dharan, Nepal. Method This study comprised of a sample of 200 adult individuals. All data were collected by performing clinical examinations in accordance with the World Health Organization Oral Health Surveys Basic Methods Criteria. It included the Community Periodontal Index and dental prosthesis examination. Result A descriptive analysis was performed and odds ratio (1.048) and 95% confidence interval (1.001; 1.096) was found out. The mean age of the population participated in the study was 41.82 ± 14.80 years. A total of 93 (46.5%) males and 107 (53.5%) females participated in the study. Among these subjects, 100% presented some periodontal problems. The statistical analysis indicated that the probability of periodontal disease with regards to wearing partial dentures was not significant as suggested by the odds ratio (1.048). Conclusion There is no association of the wearing of dental prosthesis (RPD and/or FPD) with the periodontal disease and suggests a need for populations based oral health education programs, plaque control programs to reduce the incidence of periodontal disease.

    In recent years, several new periodontal taxa have been associated with the etiology of periodontitis. A recent systematic review provides further support for the pathogenic role of 17 species/phylotypes. Thus, the aim of this study was to assess the prevalence and levels of these species in subjects with generalized chronic periodontitis (GChP; n = 30), generalized aggressive periodontitis (GAgP; n = 30), and periodontal health (PH; n = 30). All subjects underwent clinical and microbiological assessment. Nine subgingival plaque samples were collected from each subject and analyzed for their content of 20 bacterial species/phylotypes through the RNA-oligonucleotide quantification technique. Subjects from the GChP and GAgP groups presented the highest mean values for all clinical parameters in comparison with the PH group (P GChP and GAgP showed significantly higher mean levels of Bacteroidetes sp. human oral taxon (HOT) 274, Fretibacterium sp. HOT 360, and TM7 sp. HOT 356 phylotypes, as well as higher mean levels of Filifactor alocis, Fretibacterium fastidiosum, Porphyromonas gingivalis, Tannerella forsythia, and Selenomonas sputigena species than PH subjects (P GChP subjects (P GChP and GAgP than in PH subjects. Mean levels of P. gingivalis (r = 0.68), T. forsythia (r = 0.62), F. alocis (r = 0.51, P = 0.001), and Fretibacterium sp. HOT 360 (r = 0.41) were correlated with pocket depth (P < 0.001). In conclusion, Bacteroidales sp. HOT 274, Desulfobulbus sp. HOT 041, Fretibacterium sp. HOT 360, Fretibacterium sp. HOT 362, and TM7 sp. HOT 356 phylotypes, in addition to F. alocis, F. fastidiosum, and S. sputigena, seem to be associated with periodontitis, and their role in periodontal pathogenesis should be further investigated. © International & American Associations for Dental Research 2016.

    Full Text Available Rapidly Progressive Periodontitis (RPP is a severe form of a periodontal disease which starts since a puberty age. The disease if a generalized periodontal destruction without a specific distribution mode: it develops more progressively but does not in accordance to local factors. The first step to the RPP treatment is initial therapy: i.e. DHE, scaling and root planing, and eliminating predisposing local factors and continued with a maintence therapy which will support the success of a surgery later. A study case: a 21-year old RPP woman showed hyperaemia, an abscess, a 10 mm mesial pocket depth, a 5 mm distal pocker depth, a 5 mm buccal pocket depth, a 2nd degree tooth mobility and a 3 mm buccal recession on 25. In the initial therapy she was given an amoxicillin, a metronidazole for killing a supra and subgingival baterial, vitamins B and C, and also a chlorhexidine 0.2% mouth wash for a week. After a week the abscess and the inflammation decreased, but the mobility was still in the same condition and the DHE was still evaluated because of the patient's social factor, the FO was delayed. The next visit was done every 2 monts for a year for maintenance care. The clinical result showed the gingival inflammation and the tooth mobility disappeared. Radiographically, the alveolar bone showed more radiopaque and the lamina dura was seen. In conclusio, the initial and the maintenance therapy was seen to heal the RPP.

    Oral diseases qualify as major public health problems due to their high prevalence and incidence. They usually affect poor and marginal segments of the population. This study focused on the prison population that is characterized by poor living conditions and malnutrition. The aim of study was to assess the need for periodontal care in prisoners serving time in the Dakar region of Senegal. This cross-sectional study included 375 prisoners serving in three facilities, i.e. the penal camp, Liberte VI prison for women, and Rufisque prison for women. Data were collected using a modified WHO information sheet. The community periodontal index of treatment needs (CPITN) was used for scoring. Statistical analysis with stratification by sex and age was performed and tests were considered as significant for p prison time was 39.29 months +/- 17.73. The proportion of prisoners needing periodontal treatment increased gradually according to prison time with significant differences (p prison time would reduce the need for periodontal treatment in prisons in Dakar.

    To evaluate the DEC1 expression of periodontal ligament tissue and gingival tissue in the patients with chronic periodontitis. 20 non-smoking patients with chronic periodontitis and 20 healthy individuals were enrolled. Periodontal ligament tissue and gingival tissue samples from healthy subjects were collected during teeth extraction for orthodontic reason or the third molar extraction. The parallel samples from patients with chronic periodontitis were obtained during periodontal flap operations or teeth extraction as part of periodontal treatment. The DEC1 expression and the alkaline phosphatase (ALP) activity of both the periodontal ligament tissue and gingival tissue were determined by Western blot, Immunohistochemistry and ALP Detection Kit. The DEC1 expression of periodontal ligament tissue in the patients with chronic periodontitis decreased significantly along with the decreased ALP activity. On the contrary, the DEC1 expression of gingival tissue in the patients with chronic periodontitis increased significantly. Further study found that the DEC1 expression of gingival tissue increased mainly in the suprabasal layer of gingival epithelial cells but decreased in the gingival connective tissue of the patients with chronic periodontitis. The DEC1 expression decreases in the periodontal ligament tissue which is related to the osteogenic capacity, whereas the DEC1 expression increases in the suprabasal layer of gingival epithelial cells which are involved in immune inflammatory response in the patients with chronic periodontitis. The findings provide a new target to explore the pathology and the therapy of periodontitis. Copyright © 2014 Elsevier Ltd. All rights reserved.

  19. The emerging roles of B cells as partners and targets in periodontitis.

    Initial studies of periodontal disease suggested that T cell-mediated immunity against oral Gram-negative microorganisms is a key player in the pathogenesis of this inflammatory disease. Recent investigations, however, revealed that B cells are also engaged. Given their chief role in innate-like and adaptive immune responses, B cells could exert protective functions in periodontitis. However, the periodontal bacteria-specific antibody response is generally unable to halt disease progression in affected subjects, suggesting that the antibodies produced could exhibit low anti-bacterial blocking functions or opsonophagocytic potential, and/or unfavorable effects. Moreover, although microbial antigens are involved in the induction of the inflammatory responses in human adult periodontitis, endogenous antigens also may contribute to the chronicity of this common disease. Not only antibodies to self-antigens, such as collagen, are locally produced, but the autoreactivities observed in aggressive periodontitis are more severe and diverse than those observed in chronic periodontitis, suggesting that autoimmune reactivity could play a role in the tissue destruction of periodontal disease. Further support for a pathological role of B cells in periodontitis comes from the finding that B cell-deficient mice are protected from bacterial infection-induced alveolar bone loss. Studies in patients indicate that B cells and plasma cells, together with osteoclastogenic factors (RANKL and osteoprotegerin) and specific cytokines involved in their growth and differentiation (BAFF and APRIL) participate in the induction of the pathological bone loss in periodontitis. This novel insight suggests that selective targeting of B cells could represent a future therapeutic avenue for severe periodontal disease.

    2017-06-01

    The oral health of children and adolescents mirrors their general health. Because oral health care is often delivered in isolation from general health care, oral signs and symptoms do not always alert practitioners to their significance beyond the mouth. An important example of this is the association of a higher risk of dental caries and periodontal disease in children and adolescents with overweight, obesity and prediabetic conditions. Oral-health practitioners need to consider the health conditions that their patients may have. This will aid in diagnosis and alert the practitioner to oral conditions that may not resolve without general health-care intervention also. This paper reviews the more common oral conditions involving periodontal health in children and adolescents, and discusses the diagnosis of these conditions, potential associated health problems and the roles of pediatric dentistry and periodontology in the management of these conditions with the goal of children entering adulthood with healthy dentitions. © 2017 John Wiley & Sons A/S.

Before initiation of any periodontal treatment, saliva and serum samples were collected and clinical periodontal measurements were recorded from 94 participants (25 aggressive periodontitis patients, 25 chronic periodontitis patients, 44 periodontally healthy individuals). IL-21, IL-33 and PGE2 levels in serum and saliva samples were determined by ELISA. Data were tested statistically using Kruskal-Wallis, Mann-Whitney U-, and Spearman-rho rank tests. Saliva IL-33 levels were statistically significantly higher in the chronic than the aggressive group (p periodontitis groups. Saliva IL-33 levels correlated with age in the chronic periodontitis group (p periodontitis groups (p chronic and aggressive periodontitis, but the present findings support the role of these cytokines in periodontitis. Statistically significantly higher saliva IL-33 levels in the chronic periodontitis group warrant further research.

    Full Text Available Vascular disorders play a significant role in the development of dystrophic inflammatory process. There is a direct correlation between the degree of damage to blood vessels in the jaw and a depth of the destructive process in periodontal tissue. A certain role is played by endogenous factors, such as: age, vitamin deficiency, diabetes mellitus, essential hypertension and others. Clinical and epidemiological studies using pathological techniques showed significant changes in vascular wall of the artery in the periodontium, the interdental artery in particular.  Atherosclerosis, essential hypertension and periodontal pathology were proven to occur in individuals older than 40 years. The objective of the research was to determine periodontal tissue status in patients with stage II hypertension and generalized periodontitis of II degree of severity. Materials and methods. The study involved 36 patients with stage II hypertension and generalized periodontitis of II degree of severity (the main group. The patients’ age ranged from 35 to 54 years. The control group included 10 patients of corresponding age without generalized periodontitis and somatic pathology. To assess the status of periodontal tissues, we applied the Papillary-Marginal-Attached Index and the Community Periodontal Index of Treatment Needs. When diagnosing periodontal disease, the classification of M.F. Danilevskyi was used. Results. The analysis of the indicators of the Community Periodontal Index of Treatment Needs index showed the following results: in patients of the main group, the index was 2.38±0.07 points (p<0.001 pointing out a need for a course of professional oral hygiene. In patients of the control group, the index was 0.5±0.17 points indicating that there was no need for treatment, however, there was a need for improving oral hygiene. The indicators of the Papillary-Marginal-Attached Index in the main group were 55.49±1.96 points pointing out a severe degree of

  4. Periodontal treatment effects on endothelial function and cardiovascular disease biomarkers in subjects with chronic periodontitis: protocol for a randomized clinical trial

    2011-01-01

    Background Periodontal disease (PD) is an infectious clinical entity characterized by the destruction of supporting tissues of the teeth as the result of a chronic inflammatory response in a susceptible host. It has been proposed that PD as subclinical infection may contribute to the etiology and to the pathogenesis of several systemic diseases including Atherosclerosis. A number of epidemiological studies link periodontal disease/edentulism as independent risk factor for acute myocardial infarction, peripheral vascular disease, and cerebrovascular disease. Moreover, new randomized controlled clinical trials have shown an improvement on cardiovascular surrogate markers (endothelial function, sICAM, hsPCR level, fibrinogen) after periodontal treatment. Nonetheless, such trials are still limited in terms of external validity, periodontal treatment strategies, CONSORT-based design and results consistency/extrapolation. The current study is designed to evaluate if periodontal treatment with scaling and root planning plus local delivered chlorhexidine improves endothelial function and other biomarkers of cardiovascular disease in subjects with moderate to severe periodontitis. Methods/Design This randomized, single-blind clinical trial will be performed at two health centers and will include two periodontal treatment strategies. After medical/periodontal screening, a baseline endothelium-dependent brachial artery flow-mediated dilatation (FMD) and other systemic surrogate markers will be obtained from all recruited subjects. Patients then will be randomized to receive either supragingival/subgingival plaque cleaning and calculus removal plus chlorhexidine (treatment group) or supragingival plaque removal only (control group). A second and third FMD will be obtained after 24 hours and 12 weeks in both treatment arms. Each group will consist of 49 patients (n = 98) and all patients will be followed-up for secondary outcomes and will be monitored through a coordinating

    Background: The relationship between periodontal disease and dental pulp changes is controversial and has been debated for many years. This human study was performed to evaluate the possible effects of moderate to advanced periodontal disease on the different aspect of dental pulp structure. Materials and Methods: Twenty hopeless permanent teeth were extracted from systemically healthy adults because of moderate to advanced chronic periodontitis, with a bone loss of >6 mm and a mobility of grade 2 or 3. Upon extraction, the apical 2 to 3 mm of the roots were immediately sectioned. Four to five sections were mounted on each slide, and every third slide was stained with hematoxylin and eosin. The specimens were histologically processed and examined by an oral pathologist. Results: Non-inflamed pulp, with partial or complete necrosis in some sections and several non-necrotic sections, was found in only 6.3% of teeth. Most teeth (58.3%) displayed edematous pulps. Slightly fibrotic pulps were seen in 52.1% of sections. Odontoblastic integrity was seen in 31.3% of teeth. Most teeth (77.1%) displayed no pulp stones. In 43.8% of teeth, the pulp vessels displayed dilatation. Conclusions: Moderate to advanced periodontal disease can affect the dental pulp. Careful consideration of diagnostic and treatment planing in patients with endodontic-periodontal involvement is therefore recommended. PMID:23493524

    The aim of this clinical cross-sectional study was to determine the level of active matrix metalloproteinase-8 (aMMP-8) and periodontal pathogenic bacteria in gingival crevicular fluid in patients with rheumatoid arthritis (RA) with varying periodontal conditions. In total, 103 patients with RA and 104 healthy controls (HC) were included. The assessment of periodontal status included periodontal probing depth, bleeding on probing and clinical attachment loss. Periodontal disease was classified as healthy/mild, moderate or severe. For the determination of aMMP-8 levels using enzyme-linked immunosorbent assay and periodontal pathogenic bacteria using polymerase chain reaction, samples of gingival crevicular fluid were taken from the deepest gingival pockets. The statistical analyses used included a Mann-Whitney U-test, a chi-squared test or a Fisher's exact test, and the significance level was set at α = 5%. We found that 65% of patients with RA and 79% of HC had moderate to severe periodontal disease (p = 0.02). The prevalence of periodontal pathogens was almost equal (p > 0.05). Furthermore, depending on periodontal disease severity only minor differences in bacterial prevalence were detected. With increasing severity of periodontal disease, higher aMMP-8 levels were observed. Accordingly, a significant difference in patients with moderate periodontal disease (RA: 15.3 ± 13.8; HC: 9.1 ± 9.1; p ≤ 0.01) and severe periodontal disease (RA: 21.7 ± 13.3; HC: 13.1 ± 8.6; p = 0.07) was detected, with a greater tendency in the latter group. The increased aMMP-8 levels in the RA group indicate that the presence of RA appears to have an influence on the host response at a comparable level of bacterial load and periodontal disease severity. © 2017 John Wiley & Sons A/S.

    Full Text Available Hepatitis C virus (HCV infections could have an important impact on the oral health status of patients, favoring conditions such as periodontal disease and oral cancer. The review of the existing scientific literature written in English was performed, searching for oral and periodontal manifestations of HCV infection and its impact on the oral fluids. HCV infection can determine direct extrahepatic manifestations at the oral and periodontal level including oral lichen planus, Sjögren-like sialadenitis, and oral cancer. The changes caused by the infection in the subjects’ immune system, diet, and lifestyle can facilitate the development of oral conditions such as periodontal disease. Important changes also occur in the composition of the infected patients’ saliva and gingival fluid. HCV-infected patients need to be carefully monitored in terms of oral health since the infection with the virus can result in oral complications. The cellular and molecular particularities of the gingival fluid of HCV-infected patients can answer some questions regarding its impact upon periodontium impairment and whether this refers to a possible bidirectional relationship, with hepatic biomarker adjustments being induced by the periodontal patients’ inflammatory status.

  9. Redesigning ambulatory care business processes supporting clinical care delivery.

    1997-04-01

    The first step in redesigning the health care delivery process for ambulatory care begins with the patient and the business processes that support the patient. Patient-related business processes include patient access, service documentation, billing, follow-up, collection, and payment. Access is the portal to the clinical delivery and care management process. Service documentation, charge capture, and payment and collection are supporting processes to care delivery. Realigned provider networks now demand realigned patient business services to provide their members/customers/patients with improved service delivery at less cost. Purchaser mandates for cost containment, health maintenance, and enhanced quality of care have created an environment where every aspect of the delivery system, especially ambulatory care, is being judged. Business processes supporting the outpatient are therefore being reexamined for better efficiency and customer satisfaction. Many health care systems have made major investments in their ambulatory care environment, but have pursued traditional supporting business practices--such as multiple access points, lack of integrated patient appointment scheduling and registration, and multiple patient bills. These are areas that are appropriate for redesign efforts--all with the customer's needs and convenience in mind. Similarly, setting unrealistic expectations, underestimating the effort required, and ignoring the human elements of a patient-focused business service redesign effort can sabotage the very sound reasons for executing such an endeavor. Pitfalls can be avoided if a structured methodology, coupled with a change management process, are employed. Deloitte & Touche Consulting Group has been involved in several major efforts, all with ambulatory care settings to assist with the redesign of their business practices to consider the patient as the driver, instead of the institution providing the care.

    2016-06-01

    Full Text Available Iatrogenic factors refer to anyinadequate medical treatment or diagnostic proceduresconducted inadvertently by practitioners who precipitate adverse injuries or symptoms. The unavoidable consequences of these factors should be corrected promptly, as they may result in erroneous treatment or new injury either on the tooth or the periodontium or both. Periodontal disease has a multifactorial etiology, which results from the interaction of local and systemic factors, intrinsically or extrinsically. Therefore, in most cases of periodontal disease, aninterdisciplinary approach is needed, such as restorative treatment of interproximal cavities that may induced food impacted. In contrary, a periodontal therapy could also act as an iatrogenic factor in the case of dentinal hypersensitivity or gingival recessionthat frequently creates an adverse effect in esthetic. Our discussion here is presented so that dentists could treat carefully and give a lot of attention to potential danger of other consequences of iatrogenic factors.

    Eugenol is a godsend to dental care due to its analgesic, local anesthetic, and anti-inflammatory and antibacterial effects. The aim of the present research work was to prepare, characterize and evaluate eugenol-loaded nanocapsules (NCs) against periodontal infections. Eugenol-loaded polycaprolactone (PCL) NCs were prepared by solvent displacement method. The nanometric size of the prepared NCs was confirmed by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and atomic force microscopy (AFM). The in vitro drug release was found to follow a biphasic pattern and followed Michaelis-Menten like model. The percentage cell viability values near to 100 in the cell viability assay indicated that the NCs are not cytotoxic. In the in vivo studies, the eugenol NC group displayed significant difference in the continuity of epithelium of the interdental papilla in comparison to the untreated, pure eugenol and placebo groups. The in vivo performance of the eugenol-loaded NCs using ligature-induced periodontitis model in rats indicated that eugenol-loaded NCs could prevent septal bone resorption in periodontitis. On the basis of our research findings it could be concluded that eugenol-loaded PCL NCs could serve as a novel colloidal drug delivery system for enhanced therapeutic activity of eugenol in the treatment of periodontal infections.

    The aim of this study was the investigation of concentration and prevalence of selected periodontal pathogenic bacteria and concentration of active matrix-metalloproteinase-8 (aMMP-8) within a group of patients with inflammatory bowel diseases (IBD) and to compare the results with a group of healthy control subjects (HC). 59 IBD patients with Crohn`s disease (CD, n = 30) or ulcerative colitis (UC, n = 29) and 59 HC were included in this cross-sectional study. Based on periodontal probing depth (PPD) and clinical attachment level (CAL), periodontitis was classified into healthy/mild, moderate or severe. aMMP-8 was analyzed from gingival crevicular fluid using enzyme linked immunosorbent assay. Eleven selected periodontal pathogenic bacteria were analyzed in subgingival plaque samples using polymerase chain reaction. IBD patients showed higher CAL (p periodontitis (p = 0.04), gingival bleeding (p periodontitis was associated with an increase in aMMP-8 concentration (p = 0.02). The prevalences of Eubacterium nodatum and Eikanella corrodens were significantly lower in IBD compared to HC (p = 0.01). Additionally, the prevalence of Eikanella corrodens was significantly higher in CD compared to UC group (p = 0.04). Further statistically significant differences in selected bacteria between IBD and HC or CD and UC groups could not be found (p > 0.05). The results reveal changes in host immune response of IBD patients in terms of aMMP-8. Only in CD increasing aMMP-8 was associated with severity of periodontal disease. The role of periodontal pathogenic bacteria in the interrelation between IBD and periodontitis remains unclear. This article is protected by copyright. All rights reserved.

    The aim was to compare the detection frequency of periodontopathogens by using the Pado Test 4.5 and checkerboard DNA-DNA hybridization technique in chronic periodontitis patients. Thirty patients with chronic periodontitis were tested cross-sectionally with DNA/RNA oligogenomic probe method (IAI Pado Test 4.5) and DNA/DNA whole genomic probe (checkerboard) method. Samples were taken by two paper points at the deepest site in each of the four quadrants and pooled into one sample for each of the two methods. The samples were sent to the two laboratories (IAI, Zuchwil, Switzerland, and Oral Microbiology Laboratory, University of Gothenburg, Sweden) and were analyzed in a routine setting for the presence and amount of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola. While Pado Test 4.5 detected the four periodontal pathogens in 11 (36.7%) of the patients, the checkerboard method showed presence in all patients (100%) using the lower score (Score 1 corresponding to 104 bacterial cells) and 16 (53.3%) using a higher treshold (score 3 corresponding to between >105 and 106 cells). The results of the present study showed low agreement for a positive microbiological outcome using the two diagnostic methods. It was also concluded that microbiological analysis in practice should include a larger number of bacterial species to better serve as markers for a diseased associated flora in chronic periodontitis cases.

    With 39,359 entries on PubMed, periodontal medicine has a prominent position in periodontal research. Good patient care requires well-advised physicians, and whereas the dental community is informed about the relationships between periodontal diseases (PDs) and an increasing number of systemic pathologies, we wondered whether general practitioners were too. Thus, we aimed to evaluate their knowledge of the links between periodontal and systemic diseases. To this end, we sent an electronic questionnaire to the 2350 general practitioners registered to the URPS (Union régionale des Professionnels de Santé) of Midi-Pyrénées, France. They were asked about their practice, their attitude during a medical examination, and their knowledge about PDs. The analysis of 222 properly answered questionnaires showed that while most general practitioners are aware of the relationships between PDs and diabetes or cardiovascular diseases, the majority of them are unaware that obesity and respiratory and joint diseases are also concerned. Indeed, 94% of the questioned subjects consider their insight of PDs to be insufficient. Nevertheless, more than half of the interrogated physicians cared about their patients' oral health and dental care. Education regarding relationships between periodontal and systemic diseases must be improved among general practitioners who are in the front line to refer high-risk patients to a periodontist.

    Growth/differentiation factor-5 (GDF-5) plays critical roles in mesenchymal cell differentiation and stimulates human periodontal ligament cell proliferation. Potentially, GDF-5 may also play roles in wound healing including periodontal regeneration and alveolar augmentation. The objective of this review was to provide up-to-date information from pre-clinical/clinical studies evaluating GDF-5 for these indications. A comprehensive search using PubMed and Google search engines was conducted to identify reports on GDF-5 applied to periodontal and alveolar indications. Two reviewers independently screened the titles and abstracts from a total of 479 reports. Full-length articles of 17 pre-clinical and four clinical studies were selected and reviewed. Canine-, porcine- and non-human primate-based models as well as human clinical trials were used in the evaluation of GDF-5 in support of periodontal regeneration and alveolar augmentation. An absorbable collagen sponge (ACS), β-tricalcium phosphate (β-TCP) and a poly(lactic-co-glycolic) acid (PLGA) were evaluated as candidate carriers for GDF-5 using various dose and healing intervals demonstrating significantly enhanced periodontal regeneration/alveolar augmentation including cementum, periodontal ligament and alveolar bone with limited, if any, adverse effects. Growth/differentiation factor-5 supports periodontal regeneration/alveolar augmentation without aberrant healing events documented in qualified pre-clinical models and clinical pilot studies. In perspective, GDF-5 appears a promising technology for periodontal regeneration/alveolar augmentation. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available The present study evaluates the potential association of periodontal diseases among the indigenous "Garo" population in Bangladesh with their lifestyle, diabetes mellitus and routine oral health care practices. Adult males and females of the community were selected for the study. Data were recorded through one to one, face-to-face interview using a set of standard questionnaire. All teeth except the third molars were examined at 6 sites for gingival colour and swelling, bleeding on probing, probing pocket depths (PPD and clinical attachment level (CAL. Gingival Index (GI was recorded according to Loe and Silness. The greatest score for each of the 6 sites was used for assessing the PPD and CAL. Of 240 subjects, 64% were female. The mean number of teeth present was 26, and the mean number of affected teeth was 8.9 (PPD ≥3 mm. The mean ± standard deviations of GI, PPD and CAL of the community were 0.43±0.70, 2.34±0.47 and 2.70±0.77 respectively. Betel-leaf was chewed by 75%, 57.5% were tooth brush user and remaining 42.5% used traditional ways. A statistically significant difference in PPD and CAL was found between smokers and non-smokers; tooth-brush users and non-users; diabetics and non-diabetics. PPD and CAL were significantly high among frequent betel-leaf chewers and in older age-group. Without having an access to a professional dentist or part of any oral health care awareness programme, the relatively low prevalence of periodontal diseases can possibly be attributed, in part, to the traditional eating habits of the indigenous "Garo" population.

    Dental plaque-induced periodontal diseases are common in children and adults. Guidelines were previously not available for the periodontal screening of under 18s. However, new guidelines have been introduced by the British Society of Periodontology and the British Society of Paediatric Dentistry which set out recommendations for the periodontal screening and management of under 18s in primary dental care. This article provides a practical guide for general dental practitioners on how to use the BPE in children and adolescents, and highlights the importance of early detection and management of periodontal diseases in this age group. A failure to use the modified BPE in a young patient who is later diagnosed with periodontitis may leave a dentist vulnerable to a medico-legal complaint or claim. New BPE guidelines for children and adolescents have been introduced by the BSPD and BSP; it is important that all dentists are aware of these guidelines and how to implement them in general practice.

    Full Text Available Background: A supportive needs assessment is an essential component of any care program. There is no research evidence regarding the supportive care needs of cancer patients in Iran or other Middle Eastern countries. Aims: The aim of this study was to determine the supportive care needs of Iranian cancer patients. Materials and Methods: This descriptive study was conducted in a referral medical center in the northwest of Iran. A total of 274 cancer patients completed the Supportive Care Needs Survey (SCNS-59. Descriptive statistics were used for data analysis. Results: In 18 items of the SCNS, more than 50% of the participants reported that their needs were unmet. Most frequently, unmet needs were related to the health system, information, physical, and daily living domains, and most met needs were related to sexuality, patient care, and support domains. Conclusions: Iranian cancer patients experience many unmet needs and there is an urgent need for establishing additional supportive care services in Iran.

    Regardless of advances in diagnosis and treatment during the past 40 years, the overall 5-year survival rates for oral and oropharyngeal squamous cancers have only slightly improved and remain around 50%. Thus, the early diagnosis and treatment of carcinoma by health care providers are essential in achieving a good prognosis. We report a case of invasive squamous cell carcinoma that presented as a benign endodontic-periodontic lesion with a 7-mm periodontal pocket on tooth #15 in a 40-year-old, non-smoking woman. The subsequent management of the case is also discussed. The study was conducted in accordance with the Helsinki Declaration of 1975, as revised in 2000. Our patient was seen for a comprehensive periodontal examination including a periodontal charting, occlusal analysis, study casts, electronic pulp test for tooth #15, and complete mouth periapical radiographs. As there was a periapical radiolucency, an endodontic consultation was obtained. A periodontal flap surgical procedure was performed on teeth #13 to #15, and as there was bone erosion into the maxillary sinus, a biopsy of the soft tissue was submitted to the local hospital for histological analysis. The biopsied lesion was diagnosed as invasive, moderately differentiated squamous cell carcinoma with focal spindle and clear cell differentiation (grade II to III of IV). Bone invasion was also identified. The treatment of the carcinoma involved a hemimaxillectomy with the removal of the maxillary left posterior teeth. The patient remained free of tumor for 5 years after the initial presentation. Patient education and periodic oral cancer examinations by dental professionals are necessary to reduce diagnostic delay and improve prognosis. This case report emphasizes the important role of dental professionals, especially periodontists and endodontists, of being aware that squamous cell carcinoma may manifest itself clinically and/or radiographically as a common periodontal or endodontic lesion.

    2014-09-01

    Host Modulation Therapy (HMT) is a treatment concept that reduces tissue destruction and stabilizes or even regenerates inflammatory tissue by modifying host response factors. It has been used for treating osteoporosis and arthritis for several decades. However, its use in dentistry has only been recently reported. The objective of this article is to present a review of the various literatures available on HMT and also its role as adjunct therapy in periodontics. For identifying studies for this review, a PUBMED search was carried out in 2013 for all articles published till December 2012. The search was restricted to English language publications only. Longitudinal prospective and retrospective studies were included in the search. The key words used were: Host Modulation Therapy; Sub antimicrobial dose doxycycline and Non-Surgical Periodontal Therapy. The main outcomes sought were host modulation therapeutics in periodontics. Exclusion criteria included cross sectional studies, short case series as well as studies with short follow-up periods. There is a paucity of literature on HMT in periodontics although the only drug approved by United States Food and Drug Administration (FDA) is a subantimicrobial dose of doxycycline (SDD) with highly predictable results as a host modulating agent in periodontal diseases and also an effective adjunctive therapy in various diseases of periodontium. However, more randomized controlled trials are needed to obtain clinical guidelines on the usage of other host modulating agents as adjunct as well as definite therapy for periodontal diseases. SDD is an effective adjunct therapy when used in dosage of 20mg twice daily for minimum 3 months duration in various periodontal diseases with predictable clinical outcomes. It is also recommended that future clinical research on anti cytokine drugs, chemically modified tetracycline and other HMT agents should be conducted so that new drugs are available with highly predictable results.

    Full Text Available Context: Periodontal disease is caused by chronic infection inducing an inflammatory reaction leading to breakdown of tooth-supporting tissues. There are various risk factors for the disease, and smoking is one of them. Apoptosis plays a critical role in the regulation of inflammation and host immune response which helps in tissue homeostasis, and a disturbance in this is often associated with disease. The imbalance between the apoptosis and proliferation in the periodontal tissue results in periodontal disease. Neutrophils play an important role in the defense mechanism and are the most abundant immune cells in gingival inflammatory infiltrate in patients suffering from periodontal disease. Neutrophil disorders are associated with rapid destruction of periodontal tissues. Aim: To study the influence of smoking on apoptosis of neutrophils by quantifying them in the gingival connective tissue of smoking and nonsmoking subjects suffering from chronic periodontitis. Materials and Methods: Thirty gingival biopsies were harvested from 15 smoking and 15 nonsmoking subjects who suffered from chronic periodontitis. The apoptosis of neutrophils was assessed and quantified using p53 monoclonal mouse antihuman antibody. Statistical Analysis Used: Chi-square/Fisher′sexact test was used to find the significance of study parameters on a categorical scale between the two groups. Results: Neutrophil apoptosis was significantly more in the group of nonsmokers. There was no statistical difference between plaque and bleeding index, but there was a significant increase in clinical attachment loss among smokers. Conclusions: The study reveals that smoking plays a significant role in the inhibition of neutrophil apoptosis, thereby contributing to the destruction of periodontal tissues in periodontitis.

    The purpose of this study was to assess the knowledge, opinions and practice behaviors of nurse practitioners (NP) and certified nurse midwives (CNM) regarding periodontal disease and adverse pregnancy outcomes. A 45 item survey was developed, approved, pretested, revised and mailed to 404 North Carolina NPs and CNMs who provide prenatal care. Data was entered into an excel database and transferred to SPSS for Windows for complete analysis. Linear regression modeling was used to determine statistical significance. A total of 219 NPs and CNMs responded to the mailed survey, achieving a response rate of 54%. NPs and CNMs reported having limited knowledge regarding oral health. The majority felt they should collaborate with oral health care professionals to screen patients for periodontal disease. Most agreed they needed more information about periodontal disease and adverse pregnancy outcomes. NPs and CNMs who frequently examine women could serve an important role in screening for oral health problems and making appropriate dental health referrals. Increased basic and continuing education could prepare these professionals for collaborative care with oral health care professionals. This study suggests that collaboration between NPs and CNMs with dental professionals could lead to improved oral health care for pregnant patients.

    Abstract Periodontitis is a systemic and chronic inflammatory disease associated with multiple physical conditions. Distress and depression are other problems affecting the progression of periodontitis. However, the causal relationship between depression and periodontitis has not been adequately investigated. This aim of this study was to determine the association between periodontitis and the subsequent development of depression. We identified 12,708 patients with newly diagnosed periodontitis from 2000 to 2005 and 50,832 frequency-matched individuals without periodontitis. Both groups were followed until diagnosed with depression, withdrawal from the National Health Insurance program, or the end of 2011. The association between periodontitis and depressio was analyzed using Cox proportional hazard regression models. The incidence density rate of depression was higher in the periodontitis group than in the nonperiodontitis group, with an adjusted hazard ratio of 1.73 (95% confidence interval 1.58–1.89) when adjusting for sex, age, and comorbidity. Cox models revealed that periodontitis was an independent risk factor for depression in patients, except for comorbidities of diabetes mellitus (DM), alcohol abuse, and cancer. Periodontitis may increase the risk of subsequent depression and was suggested an independent risk factor regardless of sex, age, and most comorbidities. However, DM, alcohol abuse, and cancer may prevent the development of subsequent depression because of DM treatment, the paradoxical effect of alcohol, and emotional distress to cancer, respectively. Prospective studies on the relationship between periodontitis and depression are warranted. PMID:26705230

  11. Periodontitis and increase in circulating oxidative stress

    2009-05-01

    Full Text Available Reactive oxygen species (ROS are products of normal cellular metabolism. However, excessive production of ROS oxidizes DNA, lipids and proteins, inducing tissue damage. Studies have shown that periodontitis induces excessive ROS production in periodontal tissue. When periodontitis develops, ROS produced in the periodontal lesion diffuse into the blood stream, resulting in the oxidation of blood molecules (circulating oxidative stress. Such oxidation may be detrimental to systemic health. For instance, previous animal studies suggested that experimental periodontitis induces oxidative damage of the liver and descending aorta by increasing circulating oxidative stress. In addition, it has been revealed that clinical parameters in chronic periodontitis patients showed a significant improvement 2 months after periodontal treatment, which was accompanied by a significant reduction of reactive oxygen metabolites in plasma. Improvement of periodontitis by periodontal treatment could reduce the occurrence of circulating oxidative stress. Furthermore, recent studies indicate that the increase in circulating oxidative stress following diabetes mellitus and inappropriate nutrition damages periodontal tissues. In such cases, therapeutic approaches to systemic oxidative stress might be necessary to improve periodontal health.

    Chronic periodontitis is an infectious disease resulting in inflammation within the supporting tissues of the teeth, progressive attachment loss, and bone loss. In addition to declining oral health, there is always low grade infection present in periodontitis. Studies show increased levels of systemic biomarkers in periodontal disease such as CRP, which is considered a key-marker of CVD. Research has also shown positive association between BMI and smoking with periodontitis and CRP. The objective of the study was to assess the levels of CRP in patients with and without periodontitis and their relation with BMI and smoking behaviour. Patients visiting the Dental department of Bir Hospital were invited to participate in the study. Total 31 subjects in each group: Case (periodontitis) and Control (without periodontitis) were selected using convenience sampling technique. All subjects underwent periodontal examination by a single examiner. Serum CRP samples were taken before periodontal treatment. Data analysis was done by SPSS 17 software program. Increase in mean CRP levels in periodontitis (5.8595mg/L) with high statistical significance (P=0.000) in comparison to subjects without periodontitis (1.1214mg/L) was observed. BMI showed positive association with periodontitis (P=0.046) but not with CRP (0.213). Smoking behaviour showed no significant relation with either CRP (P=0.344) or periodontitis (P=0.541). We found highly significant association between periodontitis and CRP levels but not always with BMI and smoking. CRP, which is an established marker for CVD was significantly increased in periodontal infections. Hence, a close interaction among Physician, Periodontist and Patient to prevent adverse health situations is recommended.

    Periodontal disease is a bacterial biofilm-associated inflammatory disease that has been implicated in many systemic diseases. A new preventive method for periodontal disease needs to be developed in order to promote the health of the elderly in a super-aged society. The gingival epithelium plays an important role as a mechanical barrier against bacterial invasion and a part of the innate immune response to infectious inflammation in periodontal tissue. The disorganization of cell-cell interactions and subsequent inflammation contribute to the initiation of periodontal disease. These make us consider that regulation of host defensive functions, epithelial barrier and neutrophil activity, may become novel preventive methods for periodontal inflammation. Based on this concept, we have found that several agents regulate the barrier function of gingival epithelial cells and suppress the accumulation of neutrophils in the gingival epithelium. We herein introduce the actions of irsogladine maleate, azithromycin, amphotericin B, and Houttuynia cordata (dokudami in Japanese), which is commonly used in traditional medicine, on the epithelial barrier and neutrophil migration in gingival epithelial cells in vivo and in vitro , in order to provide support for the clinical application of these agents to the prevention of periodontal inflammation.

    Periodontitis is a dysbiotic inflammatory disease leading to the destruction of the tooth-supporting tissues. Current therapies are not always effective and this prevalent oral disease continues to be a significant health and economic burden. Early clinical studies have associated periodontitis with elevated complement activity. Consistently, subsequent genetic and pharmacological studies in rodents have implicated the central complement component C3 and downstream signaling pathways in periodontal host-microbe interactions that promote dysbiosis and inflammatory bone loss. This review discusses these mechanistic advances and moreover focuses on the compstatin family of C3 inhibitors as a novel approach to treat periodontitis. In this regard, local application of the current lead analog Cp40 was recently shown to block both inducible and naturally occurring periodontitis in non-human primates. These promising results from non-human primate studies and the parallel development of Cp40 for clinical use highlight the feasibility for developing an adjunctive, C3-targeted therapy for human periodontitis.

    The experience of a pilot service involving practitioners with a special interest in periodontics is described. The service functioned as a clinical network between the primary and secondary sector and featured consultant outreach. Between June 2006 and May 2007 it experienced 441 referrals. It improved patient access to periodontal care and was successful in targeting specific disease categories and in meeting key performance indicators. The service was non-surgical and emphasised patient self-efficacy. It produced highly effective clinical outcomes. It was well accepted by both patients and referring practitioners. It did not replace the need for a consultant-led service in the eyes of the referring practitioners. The BPE was used to identify suitable patients; audit indicated that there was a tendency for practitioners to underscore the level of periodontal disease.

    Full Text Available It has been claimed that periodontal dressing reduces the risk of wound infection, bleeding and granulation tissue formation and improves tissue healing. This study sought to assess the effect of periodontal dressing on wound healing and patient satisfaction following periodontal flap surgery.This clinical trial was conducted on 33 patients presenting to Hamadan University, School of Dentistry in 2012 whose treatment plan included two periodontal surgical procedures on both quadrants of the maxilla or mandible. The variables evaluated were severity of pain, bleeding, facial swelling and ease of nutrition experienced by patient during the first 3 days after surgery and inflammation, granulation tissue formation and gingival color at 7 and 14 days. Obtained data were analyzed using SPSS version 16.0 and R software and chi-square and t-tests.The mean (±SD pain score was 1.73±1.153 and 2.79±1.933 in surgical sites with and without periodontal dressing, respectively and this difference was statistically significant (P=0.005. No significant difference was noted between sites with and without periodontal dressing in terms of swelling, bleeding, gingival consistency, granulation tissue formation, gingival color and ease of nutrition (P>0.05.According to the results of the present study, patients did not experience more bleeding, facial swelling or nutritional problems without periodontal dressing; however, the level of pain experienced was lower after surgeries with the use of periodontal dressing.

    Orthodontic treatment in adult patients is one of the most frequently encountered components involving multidisciplinary approaches. In the present report, a 28-year-old male patient was treated for localized chronic periodontitis with pocket formation, mobility, pathologic migration and malalignment of maxillary left lateral incisor tooth #22. The periodontal therapy included motivation, education and oral-hygiene instructions (O.H.I.), scaling and root planing and periodontal flap surgery. Subsequently on resolution of periodontal inflammation, orthodontic therapy was carried out using the orthodontic aligner for a period of 6 months. Post-treatment (3 years) results showed complete resolution of infrabony pocket with significant bone fill, reduced tooth mobility and complete alignment of the affected maxillary left lateral incisor, thus restoring the esthetics and function.

    Background. Since 2000, studies, experiments, and clinical observations revealed high prevalence of periodontal diseases among children and adolescents. Therefore, this paper was designed to provide an update for dental practitioners on epidemiology, microbiology, pathology, prevention, diagnosis, and treatment of periodontal diseases in children and adolescents. Methods. This paper reviews the current literature concerning periodontal diseases in pediatric dentistry. It includes MEDLINE database search using key terms: "periodontal diseases in children," "Periodontal diseasesin adolescents," "periodontal diseases risk factors," "microbiology of periodontal diseases," "classification of periodontal diseases," "epidemiology of periodontal diseases," and "treatment of periodontal diseases." Articles were evaluated by title and/or abstract and relevance to pediatric dentistry. Sixty-five citations were selected by this method and by the references within the chosen articles. A review of the comprehensive textbooks on pediatric dentistry and periodontology was done. Some recommendations were based on the opinions of experienced researchers and clinicians, when data were inconclusive.

    Periodontal disease is a common infectious disease in women of reproductive age. The disease is often not diagnosed and in studies of over 10 000 women has been associated with preterm birth, small for gestational age newborns, and preeclampsia. It has been shown in a smaller number of women that treatment of periodontal disease may reduce the rate of preterm birth. The pregnancy complications of periodontal disease may be due to lipopolysaccharide from the periodontal pockets inciting prostaglandin pathways controlling parturition. Three large randomized controlled trials of treatment of periodontal disease are underway and may provide confirmation of the importance of periodontal disease in causing complications of pregnancy.

    2012-01-01

    Ethical dilemmas are becoming increasingly common in dentistry and periodontics. Clinicians, challenged with such dilemmas, may not know how to apply the appropriate moral reasoning needed to resolve these situations especially when any of the five fundamental principles of ethics that form the foundation of the American Dental Association Principles of Ethics and Code of Professional Conduct--patient autonomy, nonmaleficence, beneficence, justice, and veracity--come into conflict with each other. The author describes one clinical case that presented with an ethical dilemma. An analytic framework, used in medicine, is introduced and used to solve the clinical case on whether to proceed with periodontal surgery on a patient who is not aware of his terminal prognosis from metastatic prostate cancer. Upon using the analytic framework, recommendations are made on the ethically appropriate path for the periodontist to follow in providing care for the patient's periodontal problem consistent with the principles of patient autonomy, respect for persons, and veracity.

    To examine the existing evidence on the relationship between periodontal disease and adverse pregnancy outcomes, we conducted a systematic review of studies published up to December 2006. Studies published in full text were identified by searching computerized databases (e.g., MEDLINE, EMBASE). A meta-analysis was performed to pool the effect size of the clinical trials. Forty-four studies were identified (26 case-control studies, 13 cohort studies, and 5 controlled trials). The studies focused on preterm low birth weight, low birth weight, preterm birth, birth weight by gestational age, miscarriage or pregnancy loss, preeclampsia, and gestational diabetes mellitus. Of the chosen studies, 29 suggested an association between periodontal disease and increased risk of adverse pregnancy outcome (odds ratios [ORs] ranging from 1.10 to 20.0) and 15 found no evidence of an association (ORs ranging from 0.78 to 2.54). A meta-analysis of the clinical trials suggested that oral prophylaxis and periodontal treatment may reduce the rate of preterm low birth weight (pooled risk ratio (RR): 0.53, 95% confidence interval [CI]: 0.30-0.95, P 0.05) or low birth weight (pooled RR: 0.86, 95% CI: 0.58%1.29, P > 0.05). The authors conclude that periodontal disease may be associated with increased risk of adverse pregnancy outcomes. More methodologically rigorous studies are needed in this field. Currently, there is insufficient evidence to support the provision of periodontal treatment during pregnancy for the purpose of reducing adverse pregnancy outcomes. Obstetricians & Gynecologists, Family Physicians. After completion of this article, the reader should be able to state that the published literature is not vigorous to clinically link periodontal disease and/or its treatment to specific adverse pregnancy outcomes, and explain that more rigorous studies with world-wide agreed-upon definitions are particularly needed before periodontal disease treatment can be recommended.

    To evaluate the subgingival prevalent rates of 6 periodontal pathogenic bacteria in gingival crevicular fluids of CP patients before and after treatment, to analyze the relationship between the prevalent variance and periodontal clinical parameters, and to provide a microbiologic method of evaluating curative effect and estimating the prognosis. Gingival crevicular fluids of 13 CP patients were collected at baseline, 2 weeks, 2 months and 4 months after periodontal mechanical treatment. Also, gingival crevicular fluids were collected from 11 healthy subjects. Six periodontal pathogenic bacteria including Actinobacillus actinomycetemcomitans (Aa), Porphyromonas gingivalis(Pg), Tannerella forsythensis (Tf), Prevotella intermedia (Pi), Fusobacterium nucleatum(Fn), Prevotella nigrescens (Pn) were detected by 16S rRNA based PCR. The PLI, PD, BI of the CP patients 2 months and 4 months after periodontal mechanical treatment were evidently less than those before treatment. These 4 months after treatment were a little more than those 2 months after. The six bacteria were more frequently detected in the CP patients at baseline than in healthy controls. The prevalent rates of Tf (42.1%, 73.7%, 70.2%), Pg (47.4%, 68.4%, 77.2%), Aa (15.8%, 22.8%, 7.0%), Pn (38.6%, 57.9%, 64.9%), Pi(15.8%, 38.6%, 42.1%) 2 weeks, 2 months and 4 months following treatment were significantly lower than those at baseline (Tf 96.5%, Pg 93.0%, Aa 36.8%, Pn 86.0%, Pi 84.2%), but the prevalent rates of all the detected bacteria 2 months after treatment were higher than those at 2 weeks after. Tf, Pg, Aa, Pn and Pi may cooperate in the development of CP. The changes of periodontal pathogenic bacteria could be detected before the changes of clinical parameters and the patients should be re-evaluated and re-treated regularly within 2 months after treatment.

    Background: Attempts to successfully regenerate lost alveolar bone have always been a clinician’s dream. Angular defects, at least, have a fairer chance, but the same cannot be said about horizontal bone loss. The purpose of the present study was to evaluate the prevalence of horizontal alveolar bone loss and vertical bone defects in periodontal patients; and later, to correlate it with the treatment modalities available in the literature for horizontal and vertical bone defects. Materials and Methods: The study was conducted in two parts. Part I was the radiographic evaluation of 150 orthopantomographs (OPGs) (of patients diagnosed with chronic periodontitis and seeking periodontal care), which were digitized and read using the AutoCAD 2006 software. All the periodontitis-affected teeth were categorized as teeth with vertical defects (if the defect angle was ≤45° and defect depth was ≥3 mm) or as having horizontal bone loss. Part II of the study comprised search of the literature on treatment modalities for horizontal and vertical bone loss in four selected periodontal journals. Results: Out of the 150 OPGs studied, 54 (36%) OPGs showed one or more vertical defects. Totally, 3,371 teeth were studied, out of which horizontal bone loss was found in 3,107 (92.2%) teeth, and vertical defects were found only in 264 (7.8%) of the teeth, which was statistically significant (P<.001). Search of the selected journals revealed 477 papers have addressed the treatment modalities for vertical and horizontal types of bone loss specifically. Out of the 477 papers, 461 (96.3%) have addressed vertical bone loss, and 18 (3.7%) have addressed treatment options for horizontal bone loss. Two papers have addressed both types of bone loss and are included in both categories. Conclusion: Horizontal bone loss is more prevalent than vertical bone loss but has been sidelined by researchers as very few papers have been published on the subject of regenerative treatment modalities for

    Background Periodontitis has been regarded as a potential risk factor for rheumatoid arthritis (RA). A systematic review is made to determine whether nonsurgical periodontal treatment in patients with RA offers benefits in terms of the clinical activity and inflammatory markers of the disease. Material and Methods A search was made of the Medline-PubMed, Cochrane, Embase and Scopus databases to identify studies on the relationship between the two disease processes, and especially on the effects of nonsurgical treatment in patients of this kind. The search was based on the following keywords: rheumatoid arthritis AND periodontitis (MeSH), rheumatoid arthritis AND periodontal treatment. Results Eight articles on the nonsurgical treatment of patients with periodontitis and RA were finally included in the study. All of them evaluated clinical (DAS28) and laboratory test activity (ESR, CRP, IL-6, TNFα) before and after treatment. A clear decrease in DAS28 score and ESR was recorded, while other parameters such as CRP, IL-6 and TNFα showed a non significant tendency to decrease as a result of treatment. Conclusions Nonsurgical treatment improved the periodontal condition of patients with periodontitis and RA, with beneficial effects upon the clinical and laboratory test parameters (DAS28 and ESR), while other inflammatory markers showed a marked tendency to decrease. However, all the studies included in the review involved small samples sizes and follow-up periods of no more than 6 months. Larger and particularly longitudinal studies are therefore needed to more firmly establish possible significant relations between the two disease processes.

    It has been revealed that atherosclerosis and periodontal disease may have a common mechanism of "chronic inflammation". Several reports have indicated that periodontal infection is related to atherosclerosis, but none have yet reported such an investigation through the cooperation of local clinics. This study was performed in local Japanese clinics to examine the relationship between periodontal disease and atherosclerosis under collaborative medical and dental care. A pilot multicenter cross-sectional study was conducted on 37 medical patients with lifestyle-related diseases under consultation in participating medical clinics, and 79 periodontal patients not undergoing medical treatment but who were seen by participating dental clinics. Systemic examination and periodontal examination were performed at baseline, and the relationships between periodontal and atherosclerosis-related clinical markers were analyzed. There was a positive correlation between LDL-C level and plasma IgG antibody titer to Porphyromonas gingivalis. According to the analysis under adjusted age, at a cut-off value of 5.04 for plasma IgG titer to Porphyromonas gingivalis, the IgG titer was significantly correlated with the level of low-density lipoprotein cholesterol (LDL-C). This study suggested that infection with periodontal bacteria (Porphyromonas gingivalis) is associated with the progression of atherosclerosis. Plasma IgG titer to Porphyromonas gingivalis may be useful as the clinical risk marker for atherosclerosis related to periodontal disease. Moreover, the application of the blood examination as a medical check may lead to the development of collaborative medical and dental care within the local medical clinical system for the purpose of preventing the lifestyle-related disease.

    Periodontal disease is among the most common inflammatory conditions which is associated with many different factors. One of the contributing factors to the pathogenesis of this condition may compromise the defensive mechanism of antioxidants. The present study evaluates the antioxidant capacity of saliva in periodontal patients before and after periodontal treatment. In this cross sectional study, 31 patients systemically healthy non smokers with chronic periodontitis were recruited. The antioxidant capacity of saliva was measured before the initial phase of periodontal therapy and after completion of the treatment. Data were analyzed using SPSS 19 software. Paired T-Test, Independent sample T-test and ANOVA tests were used as appropriated. The mean and standard deviation antioxidant capacity of the saliva after the treatment.(0.962± 0.287µM)was significantly higher than before the treatment (0.655 ± 0.281 µM ,pperiodontal treatment was higher among men than among women; however, the difference was not significant (P=0.07). The mean difference of salivary antioxidant capacity was not significantly differed among different ages (P=0.772). The antioxidant capacity of saliva was higher after periodontal therapy among patients with periodontal disease, however the change was not varied across the ages and gender. Therefore, the alterations in the defensive mechanism of antioxidants could be the key factors contribute to the pathogenesis of periodontal diseases.

    Peri-implantitis is a chronic inflammation, resulting in loss of supporting bone around implants. Chronic periodontitis is a risk indicator for implant failure. Both diseases have a common etiology regarding inflammatory destructive response. BRINP3 gene is associated with aggressive periodontitis. However, is still unclear if chronic periodontitis and peri-implantitis have the same genetic background. The aim of this work was to investigate the association between BRINP3 genetic variation (rs1342913 and rs1935881) and expression and susceptibility to both diseases. Periodontal and peri-implant examinations were performed in 215 subjects, divided into: healthy (without chronic periodontitis and peri-implantitis, n = 93); diseased (with chronic periodontitis and peri-implantitis, n = 52); chronic periodontitis only (n = 36), and peri-implantitis only (n = 34). A replication sample of 92 subjects who lost implants and 185 subjects successfully treated with implants were tested. DNA was extracted from buccal cells. Two genetic markers of BRINP3 (rs1342913 and rs1935881) were genotyped using TaqMan chemistry. Chi-square (p chronic periodontitis.

    Periodontics has a long history of utilizing advances in science to expand and improve periodontal therapies. Recently the American Academy of Periodontology published the findings of the Contemporary Science Workshop, which conducted state-of-the-art evidence-based reviews of current and emerging areas in periodontics. The findings of this workshop provide the basis for an evidence-based approach to periodontal therapy. While the workshop evaluated all areas of periodontics, it is in the area of tissue engineering that the most exciting advances are becoming a reality.

    The purpose of this study was to induce experimental periodontitis in rats previously fed diets containing arginine silicate inositol (ASI) complex and examine the biochemical, immunological, and radiological effects. Fifty two 8-week-old female Sprague Dawley rats were equally divided into four groups. The control group included those fed a standard rat diet with no operation performed during the experiment. The periodontitis, ASI I, and ASI II groups were subjected to experimental periodontitis induction for 11 days after being fed a standard rat diet alone, a diet containing 1.81 g/kg ASI complex, or a diet containing 3.62 g/kg ASI complex, respectively, for 8 weeks. Throughout the 11-day duration of periodontitis induction, all rats were fed standard feed. The rats were euthanized on the eleventh day, and their tissue and blood samples were collected. In the periodontitis group, elevated tissue destruction parameters and reduced tissue formation parameters were found, as compared to the ASI groups. Levels of enzymes, cytokines, and mediators associated with periodontal tissue destruction were lower in rats fed a diet containing ASI complex after experimental periodontitis. These results indicate that ASI complex could be an alternative agent for host modulation.

    The aim of this study is to examine whether oral hygiene and self-care, particularly in periodontal health, are associated with chronic obstructive pulmonary disease (COPD) in the Korean population. Data from the Korean National Health and Nutrition Examination Survey from 2010 to 2012 were used to assess the community periodontal index (CPI) of 5,878 participants (normal lung function: n = 5,181; obstructive spirometric pattern: n = 697) aged ≥40 years, who underwent spirometry. Participants with COPD brushed their teeth less frequently and used the following less frequently: 1) dental floss and/or interdental brush; 2) mouthwash; and 3) electric toothbrush (P periodontitis in patients with COPD (58.1%) was significantly higher than in those without COPD (34.0%, P periodontal severity. Periodontitis (CPI 3 and 4) was associated in males with COPD after adjustment for: 1) age; 2) income; 3) education; 4) smoking; 5) alcohol consumption; 6) exercise; 7) body mass index; 8) toothbrushing frequency; 9) diabetes mellitus; and 10) number of teeth (CPI 3: relative risk [RR] = 1.38, 95% confidence interval [CI] = 1.12 to 2.05; CPI 4: RR = 1.23, 95% CI = 1.06 to 1.56). Findings of this cross-sectional study suggest that COPD in males may be associated with severe periodontitis and indicates the importance of promoting dental care in patients with COPD.

  15. Definition of supportive care: does the semantic matter?

    Science.gov (United States)

    Hui, David

    2014-07-01

    'Supportive care' is a commonly used term in oncology; however, no consensus definition exists. This represents a barrier to communication in both the clinical and research settings. In this review, we propose a unifying conceptual framework for supportive care and discuss the proper use of this term in the clinical and research settings. A recent systematic review revealed several themes for supportive care: a focus on symptom management and improvement of quality of life, and care for patients on treatments and those with advanced stage disease. These findings are consistent with a broad definition for supportive care: 'the provision of the necessary services for those living with or affected by cancer to meet their informational, emotional, spiritual, social, or physical needs during their diagnostic, treatment, or follow-up phases encompassing issues of health promotion and prevention, survivorship, palliation, and bereavement.' Supportive care can be classified as primary, secondary, and tertiary based on the level of specialization. For example, palliative care teams provide secondary supportive care for patients with advanced cancer. Until a consensus definition is available for supportive care, this term should be clearly defined or cited whenever it is used.

    The treatment of oral and periodontal diseases and associated anomalies accounts for a significant proportion of the healthcare burden, with the manifestations of these conditions being functionally and psychologically debilitating. A challenge faced by periodontal therapy is the predictable regeneration of periodontal tissues lost as a consequence of disease. Growth factors are critical to the development, maturation, maintenance and repair of oral tissues as they establish an extra-cellular environment that is conducive to cell and tissue growth. Tissue engineering principles aim to exploit these properties in the development of biomimetic materials that can provide an appropriate microenvironment for tissue development. The aim of this paper is to review emerging periodontal therapies in the areas of materials science, growth factor biology and cell/gene therapy. Various such materials have been formulated into devices that can be used as vehicles for delivery of cells, growth factors and DNA. Different mechanisms of drug delivery are addressed in the context of novel approaches to reconstruct and engineer oral and tooth supporting structure. Key words: Periodontal disease, gene therapy, regeneration, tissue repair, growth factors, tissue engineering. PMID:22143705

    The purpose of this study was to assess the knowledge and awareness regarding periodontal disease and its effects on pregnancy among pregnant women in the central and eastern regions of Saudi Arabia. In this cross-sectional survey, self-administered, structured questionnaires were distributed to 300 pregnant women who were chosen randomly from attendees of maternity health care centers in the central and eastern regions of Saudi Arabia. The questions were developed from literature reviews of articles. The questionnaire addressed personal and sociodemographic variables, periodontal health awareness, and knowledge of pregnant women. The questionnaire was translated into Arabic and was pretested during the pilot study on a random sample of 50 pregnant women. Data were analyzed by χ(2) -tests, with the level of significance set at P disease could be prevented through toothbrushing and flossing. Approximately 97% of the respondents knew the negative effect of smoking, while only 12% knew there was a possible relationship between periodontal disease and adverse pregnancy outcomes. The results of this cross-sectional study found that there is limited knowledge and awareness about periodontal disease and its possible effects on pregnancy among pregnant women attending maternal health care centers in the central and eastern regions of Saudi Arabia. © 2013 Wiley Publishing Asia Pty Ltd.

    The periodontium is the supporting tissues for the tooth organ and is vulnerable to destruction, arising from overpopulating pathogenic bacteria and spirochaetes. The presence of microbes together with host responses can destroy large parts of the periodontium sometimes leading tooth loss. Permanent tissue replacements are made possible with tissue engineering techniques. However, existing periodontal biomaterials cannot promote proper tissue architectures, necessary tissue volumes within the periodontal pocket and a “water-tight” barrier, to become clinically acceptable. New kinds of small-scale engineered biomaterials, with increasing biological complexity are needed to guide proper biomimetic regeneration of periodontal tissues. So the ability to make compound structures with small modules, filled with tissue components, is a promising design strategy for simulating the anatomical complexity of the periodotium attachment complexes along the tooth root and the abutment with the tooth collar. Anatomical structures such as, intima, adventitia, and special compartments such as the epithelial cell rests of Malassez or a stellate reticulum niche need to be engineered from the start of regeneration to produce proper periodontium replacement. It is our contention that the positioning of tissue components at the origin is also necessary to promote self-organizing cell–cell connections, cell–matrix connections. This leads to accelerated, synchronized and well-formed tissue architectures and anatomies. This strategy is a highly effective preparation for tackling periodontitis, periodontium tissue resorption, and to ultimately prevent tooth loss. Furthermore, such biomimetic tissue replacements will tackle problems associated with dental implant support and perimimplantitis. PMID:26903872

    2018-01-01

    Full Text Available Periodontal disease consists of chronic gingival inflammation characterized by both degradation of the periodontal connective tissue and alveolar bone loss. Drug therapy is used as an auxiliary treatment method in severe chronic periodontitis, aggressive periodontitis, and periodontitis-associated systemic disease. Nal-P-113, a modified antimicrobial peptide, specifically replaces the histidine residues of P-113 with the bulky amino acid β-naphthylalanine, and our previous studies have verified that this novel peptide is not toxic to the human body within a certain concentration range. The objective of the present study was to evaluate the effect of Nal-P-113 on periodontal pathogens and periodontal status in clinical studies. In a split-mouth clinical trial, the pocket depth and bleeding index values tended to decrease in the experimental group compared with those in the control group. SEM results verified that Nal-P-113 restrained the maturation of plaque. Based on real-time polymerase chain reaction, the levels of Fusobacterium nucleatum, Streptococcus gordonii, Treponema denticola, and Porphyromonas gingivalis in subgingival plaque were decreased when the subjects were given Nal-P-113. Bacterial growth curve analysis and a biofilm susceptibility assay verified that Nal-P-113 at a concentration of 20 μg/mL restrained the growth of S. gordonii, F. nucleatum, and P. gingivalis and biofilm formation. Therefore, Nal-P-113 effectively reduces periodontal pathogens and ameliorates periodontal status.

    Periodontitis is a multifactorial disease, with participation of bacterial, environmental, and host factors. It results from synergistic and dysbiotic multispecies microorganisms, critical “keystone pathogens,” affecting the whole bacterial community. The purpose of this study was to review the role of Porphyromonas gingivalis in the immunopathogenesis of chronic periodontitis, with special attention paid to HmuY. The host response during periodontitis involves the innate and adaptive immune system, leading to chronic inflammation and progressive destruction of tooth-supporting tissues. In this proinflammatory process, the ability of P. gingivalis to evade the host immune response and access nutrients in the microenvironment is directly related to its survival, proliferation, and infection. Furthermore, heme is an essential nutrient for development of these bacteria, and HmuY is responsible for its capture from host heme-binding proteins. The inflammatory potential of P. gingivalis HmuY has been shown, including induction of high levels of proinflammatory cytokines and CCL2, decreased levels of IL-8, and increased levels of anti-HmuY IgG and IgG1 antibodies in individuals with chronic periodontitis. Therefore, the HmuY protein might be a promising target for therapeutic strategies and for development of diagnostic methods in chronic periodontitis, especially in the case of patients with chronic periodontitis not responding to treatment, monitoring, and maintenance therapy.

    The aim of this study was to evaluate the effects of non-surgical treatment of periodontal disease during the second trimester of gestation on adverse pregnancy outcomes. Pregnant patients during the 1st and 2nd trimesters at antenatal care in a Public Health Center were divided into 2 groups: NIG--"no intervention" (n=17) or IG--"intervention" (n=16). IG patients were submitted to a non-surgical periodontal treatment performed by a single periodontist consisting of scaling and root planning (SRP), professional prophylaxis (PROPH) and oral hygiene instruction (OHI). NIG received PROPH and OHI during pregnancy and were referred for treatment after delivery. Periodontal evaluation was performed by a single trained examiner, blinded to periodontal treatment, according to probing depth (PD), clinical attachment level (CAL), plaque index (PI) and sulcular bleeding index (SBI) at baseline and 35 gestational weeks-28 days post-partum. Primary adverse pregnancy outcomes were preterm birth (Periodontal treatment resulted in stabilization of CAL and PI (p>0.05) at IG and worsening of all periodontal parameters at NIG (pperiodontal conditions of IG and NIG were observed at 2nd examination (ppregnancy outcomes was 47.05% in NIG and 6.25% in IG. Periodontal treatment during pregnancy was associated to a decreased risk of developing adverse pregnancy outcomes [OR=13.50; CI: 1.47-123.45; p=0.02]. Periodontal treatment during the second trimester of gestation contributes to decrease adverse pregnancy outcomes.

    In the course of life the periodontum is subject to changes which may be physiological or pathological. Intraoral radiographs give insight into the hard structures of the dentomaxillar region and provides information on lesions in the bone of the periodontum in that they show radiopacities and radiolucencies caused by such lesions. In this thesis the relation is investigated between the true shape and dimensions of periodontal bone lesions and their radiographic images. A method is developed and tested of making standardized and reproducible radiographs suitable for longitudinal studies of periodontal lesions. Also the possibility is demonstrated of an objective and reproducible interpretation of radiographic characteristics of periodontal bone lesions. (Auth.)

    Talking about periodontic-orthodontic interrelationships is related primarily to the 1960s, where a generalized increase in salivary bacterial counts, especially Lactobacillus, had been shown after orthodontic band placement. The purpose of this article is to provide the dental practitioner with basic understanding of the interrelationship between periodontics and orthodontics by means of representing classical studies, and, to give an update on this topic by demonstrating the most recent opinions concerning periodontic-orthodontic interrelationships. Specific areas reviewed are the ability of orthodontic treatment to afford some degree of protection against periodontal breakdown, short-term and long-term effects of orthodontic treatment on the periodontium, and some mucogingival considerations. Topics considering orthodontic treatment in periodontally compromised patients were not included in this review. While past studies have shown that orthodontic treatment can positively affect the periodontal health, recent reviews indicate an absence of reliable evidence for the positive effects of orthodontic therapy on patients' periodontal status. Periodontic-orthodontic interrelationships are still controversial issues. However, a standard language between the periodontist and the orthodontist must always be established to eliminate the existing communications barrier, and to improve the outcomes of the whole treatment.

    Studies demonstrated that periodontitis modulates microRNA (miRNAs) expression rates in periodontal tissue. However, the relationship between periodontitis and miRNAs profile in circulation remains unclear. In this study, we investigated the effects of periodontitis on serum miRNAs profile in a rat model. Male Wistar rats (n = 32, 8 weeks old) were divided into four groups of eight rats each. The control groups received no treatment for 2 or 4 weeks. In the other two groups, periodontitis was ligature induced for 2 or 4 weeks. Serum miRNAs expression profiles of each group were compared. Ligation around teeth induced periodontal inflammation at 2 weeks and periodontal tissue destruction at 4 weeks. Microarray results showed that 25 miRNAs were expressed with a 2 difference between the control and periodontitis groups at 4 weeks. Results of real-time PCR revealed that the periodontitis group up-regulated expression rates of serum miR-207 and miR-495 at 2 weeks, and miR-376b-3p at 4 weeks (p periodontitis. © 2016 John Wiley & Sons A/S.

    Full Text Available Background. Periodontal therapy for treatment of periodontitis involves the elimination of anatomic defect. There are two primary approaches to eliminating these anatomic defects : resective (gingivectomy, osseous resection, and apically positioned flaps, and regenerative surgery (osseous graft, guided tissue regeneration, resorbable barriers, coronally position flaps. Aims. The dentist know the outcomes after periodontal surgery. References. Periodontal regeneration means healing after periodontal surgery that results in the formation of a new attachment apparatus, consisting of cementum, periodontal ligament, and alveolar bone. Periodontal repair implies healing without restoration of the normal attachment apparatus. Histologic evaluation is the only reliable method to determine the true efficacy of periodontal therapies. Discussion. The variables involved in periodontal wound healing to solve how to achieve periodontal regeneration are manipulation of progenitor cell, alteration of pathologically exposed root surfaces, exclusion of gingival epithelium, and wound stabilization. Conclusions. Periodontal surgery usually do not result in periodontal regeneration. Gingival epithelium that proliferates apically can be inhibited by stabilization of the flap margin and regenerative surgery.

    Periodontal disease (PD) and atherosclerotic vascular disease (ASVD) are both chronic inflammatory diseases with a polymicrobial etiology and have been epidemiologically associated. The purpose is to examine whether periodontal bacteria that infect the periodontium can also infect vascular tissues and enhance pre-existing early aortic atherosclerotic lesions in LDLRnull mice. Mice were orally infected with intermediate bacterial colonizer Fusobacterium nucleatum for the first 12 weeks followed by late bacterial colonizers (Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia) for the remaining 12 weeks mimicking the human oral microbiota ecological colonization. Genomic DNA from all four bacterial was detected in gingival plaque by PCR, consistently demonstrating infection of mouse gingival surfaces. Infected mice had significant levels of IgG and IgM antibodies, alveolar bone resorption, and showed apical migration of junctional epithelium revealing the induction of PD. These results support the ability of oral bacteria to cause PD in mice. Detection of bacterial genomic DNA in systemic organs indicates hematogenous dissemination from the gingival pockets. Bacterial infection did not alter serum lipid fractions or serum amyloid A levels and did not induce aortic atherosclerotic plaque. This is the first study examining the causal role of periodontal bacteria in induction of ASVD in LDLRnull mice. © FEMS 2017. All rights reserved.

Tools to measure periodontal diseases at the surveillance level have focussed on current manifestations of disease (e.g. gingival inflammation) or disease sequelae (e.......g. periodontal pocket depth or loss of attachment). All tools reviewed in this paper were developed based on the state of the science of the pathophysiology of periodontal disease at the time of their design and the need to provide valid and reliable measurements of the presence and severity of periodontal...... diseases. Therefore, some of these tools are no longer valid. Others, such as loss of periodontal attachment, are the current de-facto tools but demand many resources to undertake periodical assessment of the periodontal health of populations.

    Although recent randomized controlled trials support early palliative care for patients with advanced cancer, the specific processes of care associated with these findings and whether these improvements can be replicated in the broader health care system are uncertain. The aim of this study was to evaluate the occurrence of palliative care consultation and its association with specific processes of supportive care in a national cohort of Veterans using the Cancer Quality ASSIST (Assessing Symptoms Side Effects and Indicators of Supportive Treatment) measures. We abstracted data from 719 patients' medical records diagnosed with advanced lung, colorectal, or pancreatic cancer in 2008 over a period of three years or until death who received care in the Veterans Affairs Health System to evaluate the association of palliative care specialty consultation with the quality of supportive care overall and by domain using a multivariate regression model. All but 54 of 719 patients died within three years and 293 received at least one palliative care consult. Patients evaluated by a palliative care specialist at diagnosis scored seven percentage points higher overall (P specialist consultation is associated with better quality of supportive care in three advanced cancers, predominantly driven by improvements in information and care planning. This study supports the effectiveness of early palliative care consultation in three common advanced cancers within the Veterans Affairs Health System and provides a greater understanding of what care processes palliative care teams influence.

    The radiation therapist, concerned with the disease process and all the technical intricacies of treatment, has usually not been involved in managing the supportive aspects of caring for the patient. Yet, of the team of medical specialists and allied health personnel required in oncology, the radiation therapist is the one most responsible for overseeing the total care of the cancer patient. At times this might include emotional support, prevention and correction of tissue dysfunction, augmentation of nutrition, metabolic and electrolyte regulation, rehabilitation, and vocational support. This chapter is a brief overview of a considerable volume of literature that has occupied the interest of a rather small group of physicians, nutritionists, and psychologists. The discussion highlights the special management problems of the normal-tissue effects of radiation, the related nutritional aspects of cancer care, and certain emotional and pathologic considerations

    Full Text Available Orthodontic treatment in adult patients is one of the most frequently encountered components involving multidisciplinary approaches. In the present report, a 28-year-old male patient was treated for localized chronic periodontitis with pocket formation, mobility, pathologic migration and malalignment of maxillary left lateral incisor tooth #22. The periodontal therapy included motivation, education and oral-hygiene instructions (O.H.I., scaling and root planing and periodontal flap surgery. Subsequently on resolution of periodontal inflammation, orthodontic therapy was carried out using the orthodontic aligner for a period of 6 months. Post-treatment (3 years results showed complete resolution of infrabony pocket with significant bone fill, reduced tooth mobility and complete alignment of the affected maxillary left lateral incisor, thus restoring the esthetics and function.

    Full Text Available Context: Periodontitis is an inflammatory condition which is distinguished by the devastation of the supported tooth structures. In such inflammatory conditions, some biomarkers such as neopterin will be secreted and elevated in the body fluids, which can be used as a diagnostic marker for the present and future disease activity. Aims: Assessment of the neopterin as a biomarker in inflammatory conditions such as menopause and periodontitis. Settings and Design: A cross-sectional interventional study. Materials and Methods: Sixty female individuals with a mean age of 40–60 years with chronic periodontitis were included in this study. All were categorized into two groups of thirty each, depending on their menstrual history: Group I – thirty premenopausal women and Group II – thirty postmenopausal women. Urine and plasma were collected from both groups to estimate neopterin levels. ELISA kit was used to assess the neopterin levels at baseline and after 3 months of nonsurgical periodontal therapy (NSPT. Statistical Analysis Used: IBM SPSS version 21 software. Results: A significant depreciation in the mean values of all the parameters from baseline to 3 months (P < 0.001, in the intragroup analysis, was observed. Plasma (0.006 and urine (0.004 reduction was seen. Conclusions: In both the groups, in 3 months after NSPT, decreased neopterin levels were found, suggesting that the NSPT is the definitive therapy. Further, suggesting that, neopterin levels in the plasma and urine can be used as an index to identify the periodontal inflammation and destruction.

    To identify a causal mechanism responsible for the enhancement of insulin resistance and hyperglycaemia following periodontitis in mice fed a fat-enriched diet. We set-up a unique animal model of periodontitis in C57Bl/6 female mice by infecting the periodontal tissue with specific and alive pathogens like Porphyromonas gingivalis ( Pg ), Fusobacterium nucleatum and Prevotella intermedia . The mice were then fed with a diabetogenic/non-obesogenic fat-enriched diet for up to 3 months. Alveolar bone loss, periodontal microbiota dysbiosis and features of glucose metabolism were quantified. Eventually, adoptive transfer of cervical (regional) and systemic immune cells was performed to demonstrate the causal role of the cervical immune system. Periodontitis induced a periodontal microbiota dysbiosis without mainly affecting gut microbiota. The disease concomitantly impacted on the regional and systemic immune response impairing glucose metabolism. The transfer of cervical lymph-node cells from infected mice to naive recipients guarded against periodontitis-aggravated metabolic disease. A treatment with inactivated Pg prior to the periodontal infection induced specific antibodies against Pg and protected the mouse from periodontitis-induced dysmetabolism. Finally, a 1-month subcutaneous chronic infusion of low rates of lipopolysaccharides from Pg mimicked the impact of periodontitis on immune and metabolic parameters. We identified that insulin resistance in the high-fat fed mouse is enhanced by pathogen-induced periodontitis. This is caused by an adaptive immune response specifically directed against pathogens and associated with a periodontal dysbiosis. Published by the BMJ Publishing Group Limited.

    The multifactorial chronic inflammatory disease periodontitis, which is characterized by destruction of tooth-supporting tissues, has also been implicated as a risk factor for various systemic diseases. Although periodontitis has been studied extensively, neither disease-specific biomarkers nor therapeutic targets have been identified, nor its link with systemic diseases. Here, we analyzed the global transcriptome of periodontitis and compared its gene expression profile with those of other inflammatory conditions, including cardiovascular disease (CVD), rheumatoid arthritis (RA), and ulcerative colitis (UC). Gingival biopsies from 62 patients with periodontitis and 62 healthy subjects were subjected to RNA sequencing. The up-regulated genes in periodontitis were related to inflammation, wounding and defense response, and apoptosis, whereas down-regulated genes were related to extracellular matrix organization and structural support. The most highly up-regulated gene was mucin 4 (MUC4), and its protein product was confirmed to be over-expressed in periodontitis. When comparing the expression profile of periodontitis with other inflammatory diseases, several gene ontology categories, including inflammatory response, cell death, cell motion, and homeostatic processes, were identified as common to all diseases. Only one gene, pleckstrin (PLEK), was significantly overexpressed in periodontitis, CVD, RA, and UC, implicating this gene as an important networking link between these chronic inflammatory diseases.

    Full Text Available Conical crown-retained dentures (CCRD show a higher survival rate and greater patient satisfaction than transitional removable partial dentures during long-term follow-up. However, unsustainable denture retention force on supporting abutments after initial delivery and loss retention are frequently seen in long-term follow-up of clinical cases. The main causes are insufficient information concerning denture retention designs and the retention-tolerance of the supporting abutments. Monitoring by dental technicians of the quality of dental prostheses is critical. This case report describes an optimal method for CCRD construction that determines and distributes an optimal denture retention force on the supporting abutments to allow the patient to easily remove the denture while ensuring that the CCRD remains in place during physiologic activities. Oral rehabilitation with CCRD should consider the condition of the abutment periodontal support, the interarch occlusal relationship, supplemental fatigue of the terminal abutment, and patient's estimated bite force. The effects of friction on the abutment's inner crown were based on an optimal a angle. The dental laboratory used these measurements to fabricate a CCRD using a Koni-Meter to adjust the retention of the inner crown. This method protects the abutments and reduces the wear between the inner and outer crowns. The CCRD achieved good esthetic results and physiologic functions. Periodic long-term follow-up of the patient and CCRD after initial placement is recommended.

    Full Text Available The events leading to preterm birth are still not completely understood. A quantitative systematic review was performed to estimate the effects of periodontal care during pregnancy on preventing preterm birth and low birth weight. The meta-analysis included randomized trials with pregnant women with a diagnosis of periodontal disease before 20 weeks of gestation. Relative risk (RR with 95% confidence intervals (95%CI was calculated. We evaluated the reduction in preterm and low birth weight. Thirteen trials were included, comparing 3,576 women in intervention groups with 3,412 women receiving usual care. The meta-analysis of the effects of periodontal disease treatment during pregnancy indicated a non-significant reduction in preterm births (RR = 0.90; 95%CI: 0.68-1.19 and low birth weights (RR = 0.92; 95%CI: 0.71-1.20. The creation and examination of a funnel plot revealed clear evidence of publication bias.

    Full Text Available Evidence indicates that chronic infections and inflammation are associated with increased risk of cancer development. There has also been considerable evidence that proves the interrelationship between bacterial and viral infections and carcinogenesis. Periodontitis is a chronic oral infection thought to be caused by gram-negative anaerobic bacteria in the dental biofilm. Periodontal bacteria and viruses may act synergistically to cause periodontitis. Many studies have shown that periodontal pockets may act as reservoirs for human papilloma virus, cytomegalovirus, Epstein Barr virus, and suspected agents associated with oral cancer. Periodontitis, characterized by epithelial proliferation and migration, results in a chronic release of inflammatory cytokines, chemokines, growth factors, prostaglandins, and enzymes, all of which are associated with cancer development. This review article intends to shed light on the association between periodontal health and carcinogenesis.

    Community and individual involvement are essential needs in preventive programmes for periodontal health. Campaigns should be directed towards a better individual understanding of the importance of healthy gum tissues if a functional healthy dentition is to be retained over a lifetime. Effective awareness campaigns require not only participation and education of the general public, but also all levels of health care professionals. Awareness programmes need to be carefully planned and their messages clear, non-conflicting and regularly reinforced. The complete programme should be based on, and include, specific aims, goals, strategies, monitoring and evaluation. Oral health and hygiene promotion campaigns need careful coordination between the relevant agencies or institutions involved in their implementation, such as government agencies, professional associations, industry, aid groups and education organisations.

    It is complicated to decide the treatment plan of hopeless anterior teeth in esthetic zone due to severe periodontitis, periodontal-endodontic combined lesion or teeth trauma. The optional treatment plan for this kind of teeth includes retention after periodontal treatment, extraction and implant treatment, extraction and prosthodontic treatment and so on. To make an appropriate treatment plan, patients' periodontal conditions, periodontal biotype, local anatomy, esthetic demand, economic condition and social psychological status should be comprehensively considered. A combine of periodontal, endodontic and orthodontic therapy may achieve a good treatment effect in hopeless anterior teeth with severe periodontal destruction, tooth extrusion and occlusal trauma. In this case, a 20-year-old female who presented with symptoms of bleeding on brushing and upper incisors loosening for 1 month came to the Department of Periodontology, Peking University School and Hospital of Stomatology. The clinical examinations revealed that the patient's right upper incisor had signs of mobility (III°), intrusion of 1-2 mm, and probing depth (PD) of 9-10 mm. The periapical radiograph showed that the alveolar bone of right upper incisor absorbed horizontally to the apex. And the patients showed Angle II° malocclusion with II° overbite in anterior teeth and maxillary protrusion. A diagnosis of aggressive periodontitis and Angle II° malocclusion was made. The treatment of this patient lasts for 5 years which include periodontal initial therapy, orthodontic therapy, guided tissue regeneration (GTR) of right upper incisor and supportive periodontal therapy and the clinical result is fine. A hopeless upper incisor was successfully retained and the longtime clinical condition was stable. The strategy of retention of hopeless upper anterior teeth, the relationship of periodontal treatment and orthodontic treatment, and the indications of periodontal and orthodontic combined therapy were

    A relationship between periodontal disease and atherosclerosis has been suggested by epidemiological studies. Ligature-induced experimental periodontitis is an adequate model for clinical periodontitis, which starts from plaque accumulation, followed by inflammation in the periodontal tissue. Here we have demonstrated using a ligature-induced periodontitis model that periodontitis activates monocytes/macrophages, which subsequently circulate in the blood and adhere to vascular endothelial cells without altering the serum TNF-α concentration. Adherent monocytes/macrophages induced NF-κB activation and VCAM-1 expression in the endothelium and increased the expression of the TNF-α signaling cascade in the aorta. Peripheral blood-derived mononuclear cells from rats with experimental periodontitis showed enhanced adhesion and increased NF-κB/VCAM-1 in cultured vascular endothelial cells. Our results suggest that periodontitis triggers the initial pathogenesis of atherosclerosis, inflammation of the vasculature, through activating monocytes/macrophages. PMID:24893991

    The use of magnification to perform various procedures in medical and dental field, particularly endodontics has long been recognized. Unfortunately, its application in periodontics is not widely popularized. The objective of this article is to emphasize the application of microsurgical principles in various periodontal surgical procedures and to reinforce the incorporation of microscope into periodontal practice. The most recent periodontal journals were reviewed and a search of databases such as PubMed or Medline and Google Scholar was conducted for relevant material from published literature up to 2017. Medical Subject Headings words looked for were “periodontal microsurgery” and “minimally invasive periodontal surgery.” The available literature, specifically to periodontal surgical procedures was analyzed and compiled. The analysis indicates that incorporation of magnification in periodontal practice is associated with improved visual acuity, ergonomic benefits, decreased patient morbidity, rapid healing, and enhanced patient acceptance.

    Human periodontal ligament stem cells (hPDLSCs) transplantation represents a promising approach for periodontal regeneration; however, the cell source is limited due to the invasive procedure required for cell isolation. As human umbilical cord mesenchymal stem cells (hUCMSCs) can be harvested inexpensively and inexhaustibly, here we evaluated the regenerative potentials of hUCMSCs as compared with hPDLSCs to determine whether hUCMSCs could be used as new cell sources for periodontal regeneration. Methods The characteristics of hUCMSCs, including multi-differentiation ability and anti-inflammatory capability, were determined by comparison with hPDLSCs. We constructed cell aggregates (CA) using hUCMSCs and hPDLSCs respectively. Then hPDLSCs-CA and hUCMSCs-CA were combined with β-tricalcium phosphate bioceramic (β-TCP) respectively and their regenerative potentials were determined in a rat inflammatory periodontal defect model. Results hPDLSCs showed higher osteogenic differentiation potentials than hUCMSCs. Meanwhile, hUCMSCs showed higher extracellular matrix secretion and anti-inflammatory abilities than hPDLSCs. Similar to hPDLSCs, hUCMSCs were able to contribute to regeneration of both soft and hard periodontal tissues under inflammatory periodontitis condition. There were more newly formed bone and periodontal ligaments in hPDLSCs and hUCMSCs groups than in non-cell treated group. Moreover, no significant differences of regenerative promoting effects between hPDLSCs and hUCMSCs were found. Conclusion : hUCMSCs generated similar promoting effects on periodontal regeneration compared with hPDLSCs, and can be used as new cell sources for periodontal regeneration.

    Directory of Open Access Journals (Sweden)

    Haryono Utomo

    2006-12-01

    Full Text Available In daily dental practice, the majority of patients’ main complaints are related to pain. Most patients assume that all pains inside the oral cavity originated from the tooth. One particular case is thermal sensitivity; sometimes patients were being able to point the site of pain, although there is neither visible caries nor secondary caries in dental radiograph. In this case, gingival recession and dentin hypersensitivity are first to be treated to eliminate the pain. If these treatments failed, pain may misdiagnose as pulpal inflammation and lead to unnecessary root canal treatment. Study in pain during periodontal instrumentation of plaque-related periodontitis revealed that the majority of patients feel pain and discomfort during probing and scaling. It seems obvious because an inflammation, either acute or chronic is related to a lowered pain threshold. However, in contrast, in this case report, patient suffered from chronic gingivitis and thermal sensitivity experienced a relative pain-free sensation during probing and scaling. Lowered pain threshold which accompanied by a blunted pain perception upon periodontal instrumentation is proposed to be termed as the periodontal pain paradox. The objective of this study is to reveal the possibility of certain factors in periodontal inflammation which may involved in the periodontal pain paradox hypothesis. Patient with thermal hypersensitivity who was conducted probing and scaling, after the relative pain-free instrumentation, thermal hypersensitivity rapidly disappeared. Based on the successful periodontal treatment, it is concluded that chronic gingivitis may modulate periodontal pain perception which termed as periodontal pain paradox

    Background: The success of combined periodontal and orthodontic approach in the treatment of aggressive periodontitis patients with the pathologic extruded anterior teeth is a main concern and stability of the treatment results is an important factor to evaluate the treatment. The present study investigated the periodontal parameters at the end of the orthodontic treatment in patients with the aggressive periodontitis. Materials and Methods: Eight patients with an aggressive periodontal disease, extruded maxillary incisors, infrabony defects and probing depth of ≥5 mm were enrolled in this clinical trial (before, after). After periodontal therapy, orthodontic treatment was carried out for intrusion and alignment of teeth. Plaque index (PI), probing pocket depth (PPD), distance between incisal edge and interdental papilla, root length (RL), and defect dimensions (depth and width) were examined at the end of treatment and three as well as 6 months afterward. The data were subjected to repeated measure ANOVA test. P orthodontic approach would be a successful treatment with acceptable stability in the case of regular follow-up visits and controlled oral hygiene habits. PMID:24379862

    To assess internal medicine residents' knowledge of associations between periodontal disease and systemic illnesses, and attitudes toward patients' periodontal health. A cross-sectional survey using a self-administered questionnaire was conducted among internal medicine residents attending the Faculty of Internal Medicine 2014 Update Course organized by the National Postgraduate Medical College of Nigeria. Participants came from all over the country. Data on respondents' demographic characteristics, periodontal disease knowledge, knowledge of associations between periodontal disease and systemic illnesses, and attitudes toward patients' periodontal health were collected. Data were analyzed using Epi INFO software. The Pearson chi square test was used to measure significant association between categorical variables such as the knowledge of periodontal disease and gender, age group and designation of the participants (p ⩽ 0.05). Of 150 questionnaires distributed, 123 were returned (82% response rate); 109 questionnaires were completed properly and included in the analysis. The most common source of residents' information on oral health was television (59.4%). Only 11.2% of respondents were aware that gingival bleeding was the earliest sign of periodontal disease. Respondents correctly identified periodontal disease as a risk factor for coronary heart disease (45.9%), stroke (43.5%), hospital-acquired pneumonia (53.2%), diabetes mellitus (13.8%), and preterm birth (11%). Increased age (p = 0.032) and male gender (p = 0.022) were associated significantly with knowledge of periodontal disease as a risk factor for stroke. Higher designation (p = 0.002) and longer duration in residency training (p = 0.004) were associated significantly with knowledge of periodontal disease as risk factor for peripheral arterial disease. The majority (90.9%) of respondents had positive attitudes toward the referral of their patients for regular periodontal care. Knowledge of

    Full Text Available The complete regeneration of the periodontal tissues following periodontal disease remains an unmet challenge, and has presented clinicians with a remarkably difficult clinical challenge to solve given the extensive research in this area and our current understanding of the biology of the periodontal tissues. In particular as clinicians we look for treatments that will improve the predictability of the procedure, improve the magnitude of the effect of treatment, and perhaps most importantly in the long term would extend the indications for treatment beyond the need for single enclosed bony defects to allow for suprabony regeneration, preferably with beneficial effects on the gingival soft tissues. A rapid development in both innovative methods and products for the correction of periodontal deficiencies have been reported during the last three decades. For example, guided tissue regeneration with or without the use of bone supplements has been a well-proven treatment modality for the reconstruction of bony defects prior to the tissue engineering era. Active biomaterials have been subsequently introduced to the periodontal community with supporting dental literature suggesting that certain factors should be taken into consideration when undertaking periodontal regenerative procedures. These factors as well as a number of other translational research issues will need to be addressed, and ultimately it is vital that we do not extrapolate results from pre-clinical and animal studies without conducting extensive randomized clinical trials to substantiate outcomes from these procedures. Whatever the outcomes, the pursuit of regeneration of the periodontal tissues remains a goal worth pursuing for our patients. The aim of the review, therefore is to update clinicians on the recent advances in both materials and techniques in periodontal regenerative procedures and to highlight the importance of both patient factors and the technical aspects of

    Patil, Veena A; Desai, Manthan H

    2013-03-01

    The aim of the present study was to evaluate the effect of periodontal therapy on serum C-reactive protein (CRP) levels in patients with gingivitis and chronic periodontitis. A total of 60 subjects (30 males and 30 females) were included in the study with 20 subjects in each of the groups classified based on community periodontal index (CPI) scores: I: Healthy, II: Gingivitis, III: Mild periodontitis. Periodontal therapy was performed on groups II and III patients. Venous blood was collected from each subject at baseline and 3 months after periodontal therapy. The collected sample was subjected to biochemical analysis to detect CRP levels by using immunoturbidimetric method. The present study demonstrated that the periodontitis group had a higher mean CRP levels (2.49 ± 0.47 ng/ml) as compared to the gingivitis group (1.40 ± 0.32 ng/ml) and healthy group (0.56 ± 0.20 ng/ml). The mean CRP values after periodontal therapy were found to be reduced to 0.44 ± 0.23 ng/ml in group II and 1.30 ± 0.36 ng/ml in group III patients. Within the limitations of this study, it can be concluded that CRP level progressively increases from periodontal health to disease. A decrease in CRP levels with periodontal treatment was also observed. Due to its opsonizing abilities CRP plays an important role in the innate host defence. It can be hypothesized that CRP is a potential biomarker of periodontal disease. A number of studies have reported elevated serum CRP levels in periodontitis subjects. Long standing periodontal disease and raised CRP levels enhance the risk of cardiovascular disease, cerebrovascular accidents and preterm low birth weight infants. There is also evidence that effective periodontal therapy can lower serum CRP levels. However, the data of interventional studies on CRP in gingivitis and periodontitis is scarce.

    Oral health is essential to overall health in the prenatal period. Pregnancy is not a time to delay dental care. Several studies have shown an association between periodontal disease and poor pregnancy outcomes including preterm birth. Interventions to provide periodontal treatment to pregnant women yield inconsistent results regarding preterm birth but have established the safety of periodontal therapy during pregnancy. Postpartum, women in poor dental health readily transmit the tooth decay...

    Periodontitis is a complex immune-inflammatory disease that results from a preestablished infection in gingiva, mainly due to Gram-negative bacteria that colonize deeper in gingival sulcus and latter periodontal pocket. Host inflammatory and immune responses have both protective and destructive roles. Although cytokines, prostaglandins, and proteases struggle against microbial burden, these molecules promote connective tissue loss and alveolar bone resorption, leading to several histopathological changes, namely destruction of periodontal ligament, deepening of periodontal pocket, and bone loss, which can converge to attain tooth loss. Despite the efforts of genomics, transcriptomics, proteomics/peptidomics, and metabolomics, there is no available biomarker for periodontitis diagnosis, prognosis, and treatment evaluation, which could assist on the established clinical evaluation. Nevertheless, some genes, transcripts, proteins and metabolites have already shown a different expression in healthy subjects and in patients. Though, so far, ‘omics approaches only disclosed the host inflammatory response as a consequence of microbial invasion in periodontitis and the diagnosis in periodontitis still relies on clinical parameters, thus a molecular tool for assessing periodontitis lacks in current dental medicine paradigm. Saliva and gingival crevicular fluid have been attracting researchers due to their diagnostic potential, ease, and noninvasive nature of collection. Each one of these fluids has some advantages and disadvantages that are discussed in this review. PMID:24828325

    Full Text Available Background: Chronic periodontitis is an inflammatory disease of the supporting structures of the tooth. One of the important non-oral risk factors for periodontitis is psychosocial stress and depression. Depression affects oral health by affecting the immune system through its effects on hypothalamic pituitary axis system. Periodontal inflammatory surface area (PISA is a system used to assess inflammatory burden in the periodontal tissue. Aim: The aim of this study is to assess the relationship between PISA and depression. Settings and Design: The design of the study is case-control study. Materials and Methods: The study design is a case-control study with forty patients each in case and control groups. The periodontal inflammatory level was assessed by PISA system and the levels of depression was assessed by using Beck's Depression Inventory (BDI. Statistical Analysis: Student's t-test was used to compare PISA and BDI scores. The BDI score (mean ± standard deviation [SD] for controls was 12.75 ± 6.82 compared to 22.73 ± 4.40 for the cases. The comparison (t = 7.78 was statistically significant at P < 0.0001. The PISA score (mean ± SD for controls was 210.47 ± 76.80 compared to the PISA score of 1069.50 ± 204.21 for cases which was statistically significant (t = 24.90; P < 0.0001. Results: Significantly higher BDI scores were observed in patients with chronic periodontitis than healthy controls. Conclusion: This study clearly reveals a significant association between the severity of depression and inflammatory burden.

    Full Text Available Periodontal diseases are among the most frequent diseases affecting children and adolescents. These include gingivitis, localized or generalized aggressive periodontitis (a.k.a., early onset periodontitis and periodontal diseases associated with systemic disorders. The effects of periodontal diseases observed in adults have earlier inception in life period. Gingival diseases in a child may progress to jeopardize the periodontium in adulthood. Therefore, periodontal diseases must be prevented and diagnosed early in the life. This paper reviews the most common periodontal diseases affecting children: chronic gingivitis (or dental plaque-induced gingival diseases and aggressive periodontitis. In addition, systemic diseases that affect the periodontium in young children and necrotizing periodontal diseases are addressed. The prevalence, diagnostic characteristics, microbiology, host- related factors, and therapeutic management of each of these disease entities are discussed.

    Ehlers-Danlos syndrome (EDS) designates a heterogeneous group of connective tissue disorders characterized by skin elasticity, tissue fragility, and chronic joint pain. Dental findings have been reported with some types of EDS. This case report describes the periodontal findings in a patient with a previously undiagnosed EDS type VIII. Diagnostic aids utilized included microbial testing, histological examination, gingival crevicular fluid (GCF) analysis for the levels of C-telopeptide pyridinoline cross-links (ICTP), and genetic counseling. Periodontal treatment consisted of mechanical debridement and adjunctive antibiotic therapy. Genetic counseling and clinical presentation confirmed the diagnosis of EDS type VIII. Periodontal treatment led to marked clinical improvements and GCF levels of the bone resorptive marker ICTP were significantly reduced. The patient and her siblings are currently pursuing appropriate medical care and genetic counseling. Periodontal involvement may lead to the diagnosis of an underlying systemic condition. Identification of suspected etiological factors of periodontal disease may prove critical for the general well-being of some patients.

    No current therapy promotes root canal disinfection and regeneration of the pulp-dentin complex in cases of pulp necrosis. Antibiotic pastes used to eradicate canal infection negatively affect stem cell survival. Three-dimensional easy-to-fit antibiotic-eluting nanofibers, combined with injectable scaffolds, enriched or not with stem cells and/or growth factors, may increase the likelihood of achieving predictable dental pulp regeneration. Periodontitis is an aggressive disease that impairs the integrity of tooth-supporting structures and may lead to tooth loss. The latest advances in membrane biomodification to endow needed functionalities and technologies to engineer patient-specific membranes/constructs to amplify periodontal regeneration are presented.

    A subset of periodontal microorganisms has been associated with cardiovascular disease (CVD), which is the leading complication of type 1 diabetes (t1DM). The authors therefore evaluated the association between periodontal microorganism groups and early markers of CVD in youth with t1DM. A cross-sectional analysis was conducted among youth aged 12 to 19 years at enrollment; 105 had t1DM for ≥5 years and were seeking care at the Barbara Davis Center, University of Colorado, from 2009 to 2011, and 71 did not have diabetes. Subgingival plaque samples were assessed for counts of 41 periodontal microorganisms using DNA-DNA hybridization. Microorganisms were classified using cluster analysis into four groups named red-orange, orange-green, blue/other, and yellow/other, modified from Socransky's color scheme for periodontal microorganisms. Subsamples (54 with t1DM and 48 without diabetes) also received a periodontal examination at the University of Colorado School of Dental Medicine. Participants were ≈15 years old on average, and 74% were white. Mean periodontal probing depth was 2 mm (SE 0.02), and 17% had bleeding on probing. In multivariable analyses, glycated hemoglobin (HbA1c) was inversely associated with the yellow/other cluster (microorganisms that are not associated with periodontal disease) among youth with t1DM. Blood pressure, triglycerides, low-density lipoprotein, high-density lipoprotein, and total cholesterol were not associated with microorganism clusters in this group. HbA1c was not associated with periodontal microorganism clusters among youth without diabetes. Among youth with t1DM who had good oral health, periodontal microorganisms were not associated with CVD risk factors.

    Full Text Available AbstractBackground and Objective: Many clinical researches have been carried out to investigate the relationship between myocardial infarction (MI and periodontitis. Despite most of them indicated that the periodontitis may be associated with an increased risk of MI, the findings and study types of these studies have been inconsistent. The goal of this meta-analysis was to critically assess the strength of the association between MI and periodontitis in case-control studies.Methods: PubMed and the Cochrane Library were searched for eligible case-control studies reporting relevant parameters that compared periodontal status between MI and control subjects. The odds ratios (ORs and 95% confidence intervals (CIs from each study were pooled to estimate the strength of the association between MI and periodontitis. The mean differences and 95% CIs for periodontal-related parameters were calculated to determine their overall effects.Results: Seventeen studies including a total of 3456 MI patients and 3875 non-MI control subjects were included. The pooled OR for the association between MI and periodontitis was 2.531 (95% CI: 1.927-3.324. The mean differences (95% CIs for clinical attachment loss, probing depth, bleeding on probing, plaque index, and the number of missing teeth were 1.000 (0.726-1.247, 1.209 (0.538-1.880, 0.342 (0.129-0.555, 0.383 (0.205-0.560, and 4.122 (2.012-6.232, respectively. Conclusion: With the current evidence, the results support the presence of a significant association between MI and periodontitis. Moreover, MI patients had worse periodontal and oral hygiene status and fewer teeth than did control subjects. More high-quality and well-designed studies focusing on the casual relationship between MI and periodontitis should be conducted in the future.

  5. The owner-animal-environment triad in the treatment of canine periodontal disease.

    In a perfect world, all veterinarians and veterinary dental technicians would understand periodontal disease as well as the dental specialist. They would all be able to recognize the early signs of periodontal disease and recommend treatment to prevent its progression. The owners would have the financial resources, time, and desire to maintain their pet's oral health. The dogs would all be calm and compliant with home care and have no particular anesthetic risks. Unfortunately, this is not a perfect world. Some veterinarians do not understand periodontal disease any better that I understand cosmic string theory. Some owners have limited financial resources and are not particularly committed to their pet's oral health. Some animals will not tolerate any type or manner of home care. Given that animals, their mouths, and their owners come in an infinite variety of shapes and sizes (figuratively and literally), how can we talk about the treatment of periodontal disease as if it is a single condition with a single treatment, or even only a few treatment options? Each owner, animal, and its environment must be assessed on an individual basis to develop a treatment plan that is reasonable and attainable based on the unique circumstances of each case. So, what should be the goal when treating periodontal disease? Is it the preservation of all teeth at all costs? Is it the preservation of important teeth if the costs can be kept reasonable? I would suggest that the overriding goal of periodontal treatment should be the elimination and prevention of oral infection and oral pain. In the domestic environment, dogs have no real need to defend territory. They have no need to prehend and kill live prey animals. In short, the domesticated pet dog does not need teeth at all. This may seem like an odd statement for a veterinary dentist to make, but I feel quite strongly that a dog is far better off having no teeth than having bad teeth. My preference is that a dog should have a full

    Unlike in adults, currently there are no nationally agreed guidelines for the assessment of periodontal diseases in children and adolescents. This paper considers the range of periodontal diseases that can affect youngsters and documents a simple periodontal screening system for the younger age groups. It includes principles of periodontal diagnosis and management for the practitioner to apply to the young patient and considers when to treat in practice and when to refer to a specialist.

    Motivation plays an important role in the treatment process of chronic diseases, as treatment requires behavioural change and lifelong adherence to medical recommendations. Periodontitis is a good example of such health condition as to maintain good periodontal health patients have to adhere to a strict oral hygiene regimen. To examine whether the motivation of patients suffering from chronic periodontitis influences their clinical periodontal condition. Cross sectional study. Department of Periodontology and Oral Medicine, Dental University Clinic, Jagiellonian University, Krakow, Poland. 199 adult periodontal patients, aged 20-78 years. Questionnaire concerning patients' medical and dental history, modified Zychlińscy motivation assessment questionnaire, clinical periodontal examination. The extent of motivation. Periodontal status evaluated with the use of periodontal indices (API, BOP, CPITN). The mean motivation score was 57.4. The mean API and BOP values were 55.7% and 46.4%, respectively. For most of the patients the recorded CPITN value was 3. Correlations were observed between motivation and both API and BOP, and between API and BOP. Periodontal patients with greater motivation having better oral health (lower API and BOP) suggests an influence on the quality of their self-management of the disease (i.e. adherence to their oral hygiene regimen).

    2016-12-01

    Generalized refractory chronic periodontitis is a periodontal condition that is resistant to conventional therapy. Management of this condition often is frustrating to both the patient and the clinician. The authors present 4 cases of generalized refractory chronic periodontitis characterized by an inflammatory gingival response and progressive bone loss that did not respond to extensive periodontal treatments and regular periodontal care. Histologic examination of affected gingival tissue revealed an abundance of plasma cells, a feature seen in certain oral contact hypersensitivity reactions. The authors suspected that waxed or coated dental floss was the offending contactant, and its removal from the patients' oral hygiene regimens resulted in a dramatic improvement of the periodontal characteristics. In cases of periodontal disease as described in this report, dental practitioners should consider the possibility of a contact hypersensitivity reaction to waxed or coated dental floss, whereby the floss exacerbates the condition instead of assisting in its resolution.

  11. Emerging Concepts in the Resolution of Periodontal Inflammation: A Role for Resolvin E1

    Directory of Open Access Journals (Sweden)

    Maria G. Balta

    2017-12-01

    Full Text Available Inflammatory response is a protective biological process intended to eliminate the harmful effect of the insulting influx. Resolution of inflammation constitutes an active sequence of overlapping events mediated by specialized proresolving mediators, such as lipoxins, resolvins, protectins, and maresins, which originate from the enzymatic conversion of polyunsaturated fatty acids (PUFAs. An unresolved acute inflammatory response results in chronic inflammation, which is a leading cause of several common pathological conditions. Periodontitis is a biofilm-induced chronic inflammatory disease, which results in loss of periodontal connective tissue and alveolar bone support around the teeth, leading to tooth exfoliation. An inadequate proresolving host response may constitute a mechanism explaining the pathogenesis of periodontal disease. An emerging body of clinical and experimental evidence has focused on the underlying molecular mechanisms of resolvins and particularly Resolvin E1 (RvE1 in periodontitis. Recently, RvE1 has been directly correlated with the resolution of inflammation in periodontal disease. Herein, we provide a comprehensive overview of the literature regarding the role and possible mechanisms of action of RvE1 on different cell populations recruited in periodontal inflammation as well as its potential therapeutic implications. Along with recent data on the benefits of PUFAs supplementation in periodontal clinical parameters, we touch upon suggested future directions for research.

    Periodontitis caused by microorganisms that adhere to and grow on the tooth's surfaces, is an inflammatory diseases causing gum infection. The disease damages the soft tissues that surround and support the teeth and destroys the bone that supports teeth and finally causes tooth loss. An increased risk of stroke and heart attack problems are related to the periodontitis as well. Most bacteria or pathogens attach to gum surface where they form a biofilm. Bacterial cells in biofilms are well protected against antibiotics. The mechanisms of action are still unknown, and it is difficult to control pathogens with antibiotics in biofilm infections and thus the study on the antibiotics is needed. In this research, a number of natural water soluble, small-sized antibiotics molecules and their derivatives are studied. Molecular editing programs such as Gamess, Chemcraft and Avogadro, with an auto-optimization feature that determines the theoretical values of the structure's atomic properties are used to build virtually any molecule with the optimized geometry according to various force field options. The UFF (Universal Force Field) is used for optimizing most molecules.

    2018-03-01

    Full Text Available Chronic periodontitis is an infectious disease associated with the progressive destruction of periodontal tissues. In recent years, more and more data indicate an existing relationship between periodontal disease and rheumatoid arthritis. The link between both diseases has been confirmed in multiple studies. Despite the fact that this association might be based on shared environmental and genetic risk factors, a possible causal relation was advocated by experimental, epidemiological and interventional studies, with the leading role of Porphyromonas gingivalis. Individuals with chronic periodontitis are at an increased risk of developing rheumatoid arthritis, as well as rheumatoid arthritis patients are at an increased risk of chronic periodontitis and more severe forms of periodontitis. Furthermore, there is a correlation between the activity in both diseases – patients with more severe periodontitis suffer from more active rheumatoid arthritis. Intervention attempts were also performed, which demonstrated that eliminating periodontal infection and inflammation can affect the severity of rheumatoid arthritis. In this paper, we review the current knowledge about the link between both diseases, focusing on its clinical implications. Will periodontal treatment become a part of standard therapy for rheumatoid arthritis?

    To assess correlations between periodontal status, maternal age and adverse pregnancy outcomes, such as pre-term and low birth weight in a sample of pregnant women. Study population was represented by outpatient pregnant women, gestational age > 26 weeks. Medical history questionnaires were administered to all participants who underwent clinical evaluation; clinical obstetric outcome records were collected after delivery. A questionnaire was administered regarding personal information, socio-economic status, oral hygiene habits, and oral health conditions. A clinical oral examination was performed to collect Simplified Oral Hygiene Index (OHI-S) and Community Periodontal Index (CPI). Pregnancy outcome records included: delivery week, kind and causes of delivery, any relevant complications, and birth weight. Descriptive statistics were used to depict the data from the questionnaire while the relationship between delivery week, birth weight, maternal age and periodontal status was evaluated through multivariate tests of significance. 88 pregnant women were enrolled in the study. The results showed a statistically significant correlation (Pperiodontal disease and adverse pregnancy outcomes. No statistical correlation was found among pre-term and low birth weight, smoking, ethnicity and educational level of mothers. The results highlight the importance of including a routine oral and periodontal health examination in pregnant women older than 40 years of age. The correlation between periodontal status and adverse pregnancy outcomes in older mothers indicates the need for routine oral health examination and periodontal status assessment and care in pregnant women older than 40 years of age.

    Halitosis is a general term used to describe an unpleasant or offensive odor emanating from the oral cavity. It is a condition that has health and social implications in the life of those who suffer from it. The origin of halitosis is related to both systemic and oral conditions although the oral causes predominate. Volatile sulfur compound is the primary gas responsible for halitosis. They are formed as a result of gram-negative bacterial putrefaction. The major sites for oral halitosis are the dorsum of the tongue and periodontal pockets. There is a correlation between the amount of plaque on the tongue and periodontitis with the severity of halitosis. The aim of this article was to review the data and correlate periodontitis with severity of halitosis and the effect of halitosis- inducing factors on the progress of periodontal diseases. (author)

    In the clinical dentists and periodontal researchers' community, there is an obvious demand for a systems model capable of linking the clinical presentation of periodontitis to underlying molecular knowledge. A computer-readable representation of processes on disease development will give periodontal researchers opportunities to elucidate pathways and mechanisms of periodontitis. An ontology for periodontitis can be a model for integration of large variety of factors relating to a complex disease such as chronic inflammation in different organs accompanied by bone remodeling and immune system disorders, which has recently been referred to as osteoimmunology. Terms characteristic of descriptions related to the onset and progression of periodontitis were manually extracted from 194 review articles and PubMed abstracts by experts in periodontology. We specified all the relations between the extracted terms and constructed them into an ontology for periodontitis. We also investigated matching between classes of our ontology and that of Gene Ontology Biological Process. We developed an ontology for periodontitis called Periodontitis-Ontology (PeriO). The pathological progression of periodontitis is caused by complex, multi-factor interrelationships. PeriO consists of all the required concepts to represent the pathological progression and clinical treatment of periodontitis. The pathological processes were formalized with reference to Basic Formal Ontology and Relation Ontology, which accounts for participants in the processes realized by biological objects such as molecules and cells. We investigated the peculiarity of biological processes observed in pathological progression and medical treatments for the disease in comparison with Gene Ontology Biological Process (GO-BP) annotations. The results indicated that peculiarities of Perio existed in 1) granularity and context dependency of both the conceptualizations, and 2) causality intrinsic to the pathological processes

    Full Text Available OBJECTIVES: The aim of this study was to evaluate the effects of non-surgical treatment of periodontal disease during the second trimester of gestation on adverse pregnancy outcomes. MATERIAL AND METHODS: Pregnant patients during the 1st and 2nd trimesters at antenatal care in a Public Health Center were divided into 2 groups: NIG - "no intervention" (n=17 or IG- "intervention" (n=16. IG patients were submitted to a non-surgical periodontal treatment performed by a single periodontist consisting of scaling and root planning (SRP, professional prophylaxis (PROPH and oral hygiene instruction (OHI. NIG received PROPH and OHI during pregnancy and were referred for treatment after delivery. Periodontal evaluation was performed by a single trained examiner, blinded to periodontal treatment, according to probing depth (PD, clinical attachment level (CAL, plaque index (PI and sulcular bleeding index (SBI at baseline and 35 gestational weeks-28 days post-partum. Primary adverse pregnancy outcomes were preterm birth (0.05 at IG and worsening of all periodontal parameters at NIG (p<0.0001, except for PI. Signifcant differences in periodontal conditions of IG and NIG were observed at 2nd examination (p<0.001. The rate of adverse pregnancy outcomes was 47.05% in NIG and 6.25% in IG. Periodontal treatment during pregnancy was associated to a decreased risk of developing adverse pregnancy outcomes [OR=13.50; CI: 1.47-123.45; p=0.02]. CONCLUSIONS: Periodontal treatment during the second trimester of gestation contributes to decrease adverse pregnancy outcomes.

The conclusions of this work underline the importance for the physician/obstetrician to identify women at risk for preterm birth and to address these patients to dentist for periodontal examination and treatment in order to limit adverse pregnancy outcomes.

    Periodontitis is a multi-microbial oral infection with high prevalence among adults. Putative oral pathogens are commonly found in periodontally diseased individuals. However, these organisms can be also detected in the oral cavity of healthy subjects. This leads to the hypothesis, that alterations in the proportion of these organisms relative to the total amount of oral microorganisms, namely their abundance, rather than their simple presence might be important in the transition from health to disease. Therefore, we developed a quantitative molecular method to determine the abundance of various oral microorganisms and the portion of bacterial and archaeal nucleic acid relative to the total nucleic acid extracted from individual samples. We applied quantitative real-time PCRs targeting single-copy genes of periodontal bacteria and 16S-rRNA genes of Bacteria and Archaea. Testing tongue scrapings of 88 matched pairs of periodontally diseased and healthy subjects revealed a significantly higher abundance of P. gingivalis and a higher total bacterial abundance in diseased subjects. In fully adjusted models the risk of being periodontally diseased was significantly higher in subjects with high P. gingivalis and total bacterial abundance. Interestingly, we found that moderate abundances of A. actinomycetemcomitans were associated with reduced risk for periodontal disease compared to subjects with low abundances, whereas for high abundances, this protective effect leveled off. Moderate archaeal abundances were health associated compared to subjects with low abundances. In conclusion, our methodological approach unraveled associations of the oral flora with periodontal disease, which would have gone undetected if only qualitative data had been determined.

    Full Text Available Background/purpose: The aim of this study was to evaluate and compare the systemic levels of C-reactive protein (CRP in peripheral blood samples of patients with aggressive periodontitis during the first twelve months of periodontal treatment, at exactly six month interval measurements, and compare them with clinical periodontal parameters. Materials and methods: All patients (N = 45 were examined prior to the initiation of periodontal treatment. Patients were divided into two groups GAgP (Generalised form of aggressive periodontitis, N = 23 and group LAgP (Localised form of aggressive periodontitis, N = 22. Control group (CON included 60 individuals with healthy periodontium. The levels of CRP were determined in both groups GAgP and LAgP three times in 6 month intervals during the periodontal treatment. Results: CRP is a plasma protein that reflects the extent of the acute phase response to inflammation and is one of the markers of choice for monitoring this response. In our study, CRP levels decreased in course of periodontal treatment in both groups (GAgP and LAgP in a similar way as bleeding on probing (BOP and probing pocket depth (PPD indices. Conclusion: Our study results showed that CRP levels, as well as bleeding on probing (BOP and probing pocket depth (PPD, indices decreased in course of periodontal treatment in patients with generalised and localised aggressive periodontitis. Therefore this marker might be exploitable as a means to evaluate periodontal health in patients with aggressive periodontitis.

    Periodontal disease is frequently suggested as a possible causal factor for preterm delivery. The link between periodontal disease and preterm delivery is a possible translocation of periopathogenic bacteria to the placenta and amniotic fluid as well as a systemic response to this chronic inflammatory disease. However, there is a lack of information on whether there is an association between clinical periodontal status in women with preterm prelabor rupture of membranes (PPROM) and the presence of microbial invasion of the amniotic cavity (MIAC) and intra-amniotic inflammation (IAI). Therefore, the main aim of this study was to evaluate the incidence and severity of periodontal disease in women with PPROM. The secondary aim was to characterize an association between periodontal status and the presence of intra-amniotic PPROM complications (MIAC and/or IAI). Seventy-eight women with PPROM at gestational ages between 24 + 0 and 36 + 6 weeks were included in this study. The samples of amniotic fluid were obtained at admission via transabdominal amniocentesis, and amniotic fluid interleukin (IL)-6 concentrations were determined using a point-of-care test. All women had a full-mouth recording to determine the periodontal and oral hygiene status. Probing pocket depth and clinical attachment loss were measured at four sites on each fully erupted tooth. In total, 45% (35/78) of women with PPROM had periodontal disease. Mild, moderate, and severe periodontal disease was present in 19% (15/78), 19% (15/78), and 6% (5/78) of women, respectively. The presence of MIAC and IAI was found in 28% (22/78) and 26% (20/78) of women, respectively. Periopathogenic bacteria (2 × Streptococcus intermedius and 1 × Fusobacterium nucleatum) was found in the amniotic fluid of 4% (3/78) of women. There were no differences in periodontal status between women with MIAC and/or IAI and women without these intra-amniotic complications. The presence of MIAC and IAI was not related

    The healing of periodontal splinting can be detected both with clinical and radiographic examination. In this study, the alveolar bone was evaluated by radiographic digital periapical analysis. Periodontal tooth splinting is periodontal support therapy used to prevent periodontal injury during repair and regeneration of periodontal therapy. Radiographic digital periapical analysis of alveolar bone in the mandibular anterior region with chronic periodontitis and 2/3 cervical bone loss after three months of periodontal splinting. Eighty four proximal site (43 mesial and 41 distal) from 16 patients with chronic periodontitis and treated with spinting were examined by taking periapical digital radiographic at day 1 and 91. The bone loss, bone density and utility of lamina dura were evaluated. The statistical analysis after three months evaluation using T-test for bone loss, Wilcoxon sign rank test for bone density and utility lamina dura showed no significantly differences (pchronic periodontitis with 2/3 alveolar bone loss after three months splinting.

    Periodontal regeneration is an important part of regenerative medicine, with great clinical significance; however, the effects of nanotopography on the functions of periodontal ligament (PDL) stem cells (PDLSCs) and on PDLSC sheet based periodontal regeneration have never been explored. Titania nanotubes (NTs) layered on titanium (Ti) provide a good platform to study this. In the current study, the influence of NTs of different tube size on the functions of PDLSCs was observed. Afterward, an ectopic implantation model using a Ti/cell sheets/hydroxyapatite (HA) complex was applied to study the effect of the NTs on cell sheet based periodontal regeneration. The NTs were able to enhance the initial PDLSC adhesion and spread, as well as collagen secretion. With the Ti/cell sheets/HA complex model, it was demonstrated that the PDLSC sheets were capable of regenerating the PDL tissue, when combined with bone marrow mesenchymal stem cell (BMSC) sheets and HA, without the need for extra soluble chemical cues. Simultaneously, the NTs improved the periodontal regeneration result of the ectopically implanted Ti/cell sheets/HA complex, giving rise to functionally aligned collagen fiber bundles. Specifically, much denser collagen fibers, with abundant blood vessels as well as cementum-like tissue on the Ti surface, which well-resembled the structure of natural PDL, were observed in the NT5 and NT10 sample groups. Our study provides the first evidence that the nanotopographical cues obviously influence the functions of PDLSCs and improve the PDLSC sheet based periodontal regeneration size dependently, which provides new insight to the periodontal regeneration. The Ti/cell sheets/HA complex may constitute a good model to predict the effect of biomaterials on periodontal regeneration.

    Background To date, there is no compilation of evidence-based information associating bacteremia and periodontal procedures. This systematic review aims to assess magnitude, duration, prevalence and nature of bacteremia caused by periodontal procedures. Study Design Systematic Review Types of Studies Reviewed MEDLINE, EMBASE and LILACS databases were searched in duplicate through August, 2013 without language restriction. Observational studies were included if blood samples were collected before, during or after periodontal procedures of patients with periodontitis. The methodological quality was assessed in duplicate using the modified Newcastle-Ottawa scale (NOS). Results Search strategy identified 509 potentially eligible articles and nine were included. Only four studies demonstrated high methodological quality, whereas five were of medium or low methodological quality. The study characteristics were considered too heterogeneous to conduct a meta-analysis. Among 219 analyzed patients, 106 (49.4%) had positive bacteremia. More frequent bacteria were S. viridans, A. actinomycetemcomitans P. gingivalis, M. micros and species Streptococcus and Actinomyces, although identification methods of microbiologic assays were different among studies. Clinical Implications Although half of the patients presented positive bacteremia after periodontal procedures, accurate results regarding the magnitude, duration and nature of bacteremia could not be confidentially assessed.

    Periodontitis is an infectious polymicrobial, immuno-inflammatory disease of multifactorial aetiology that has an impact on the health, production and welfare of ruminants. The objective of the present study was to determine the microbial profiles present in the gingival sulcus of cattle considered periodontally healthy and in the periodontal pocket of animals with periodontitis lesions using high-throughput bacterial 16S rRNA gene sequencing. Subgingival biofilm samples were collected from 40 cattle with periodontitis and 38 periodontally healthy animals. In total, 1923 OTUs were identified and classified into 395 genera or higher taxa. Microbial profiles in health differed significantly from periodontitis in their composition (p PERMANOVA) but no statistically significant differences were observed in the diversity of healthy and periodontitis microbiomes. The most prevalent taxa in health were Pseudomonas, Burkholderia and Actinobacteria, whereas in disease these were Prevotella, Fusobacterium and Porphyromonas. The most discriminative taxa in health were Gastranaerophilales, Planifilum and Burkholderia, and in disease these were Elusimicrobia, Synergistes and Propionivibrio. In conclusion, statistically significant difference exists between the microbiome in bovine oral health and periodontitis, with populations showing 72.6% dissimilarity. The diversity of the bacteria found in health and periodontitis were similar and bacteria recognised as periodontal pathogens showed increased abundance in disease. In this context, the main components of bacterial homeostasis in the biofilm of healthy sites and of dysbiosis in periodontal lesions provide unprecedented indicators for the evolution of knowledge about bovine periodontitis.

    Full Text Available Purpose. The aim of this study was to analyse the levels of interleukin-6 (IL-6 and interleukin-8 (IL-8 in gingival crevicular fluid (GCF of patients with chronic periodontitis prior to and following surgical and/or nonsurgical periodontal therapy for a period of 32 weeks. Methods. GCF samples were obtained from 24 nondiseased and 72 diseased sites of 12 periodontal patients prior to as well as at 6, 16, and 32 weeks following non-surgical and surgical periodontal therapy. IL-6 and IL-8 levels were determined by enzyme-linked immunosorbent assay (ELISA. Results. Periodontal treatment improved all clinical parameters. Both treatment modalities resulted in similar IL-6 as well as IL-8 levels. Mean IL-6 and IL-8 concentrations were significantly higher in non-diseased compared to diseased sites and increased significantly following treatment in diseased sites. Mean total amounts of IL-6 and IL-8 (TAIL-6, TAIL-8 did not differ significantly between diseased and nondiseased sites, while following therapy TAIL-8 levels decreased significantly. Conclusions. The data suggest that periodontal therapy reduced the levels of IL-8 in GCF. However, a strong relationship between IL-6, IL-8 amounts in GCF and periodontal destruction and inflammation was not found.

    Periodontal disease is thought to be associated with increased risk of systemic diseases and adverse pregnancy outcomes, including pregnancy hypertension (PH). The aim of the present study is to find the prevalence of periodontal disease in females with PH in a rural-based medical institute. The present case control study was performed with 200 females, 100 with PH and 100 without PH. Antenatal periodontal screening was performed within 72 hours of their hospital admission for delivery. The periodontal parameters assessed were oral hygiene index-simplified, gingival index, mean probing depth, and loss of attachment. Prevalence of periodontal disease was 65.5% and was significantly higher (P periodontal disease and PH on bivariate multiple logistic regression analysis. Nulliparous females were at higher odds to develop periodontal disease and PH (odds ratio = 1.7; 95% CI = 0.5 to 6.1). As the severity of periodontal disease increased from moderate to severe, the severity of hypertension also increased (r(2) = 0.8 and 0.5 for moderate and severe periodontal disease, respectively). Periodontal disease is more prevalent in females with PH.

    The aim of the periodontal treatment is to provide healthy and functional dentition all through a lifetime. In this report, periodontal treatment of a 42-year-old male patient with generalized severe chronic periodontitis is presented. He received initial periodontal treatment together with adjunctive antimicrobials. The devital teeth were endodontically treated, and free gingival grafts were placed at the inadequate keratinized tissue zones before regenerative surgery. Following the surgical treatment using enamel matrix derivatives and xenogenic bone graft combination, the patient was put on a strict recall program. After 12 months, favorable clinical and radiographical improvements were obtained. The 7-year maintenance of the present case with several initially hopeless teeth has been shown and discussed in this report. It can be concluded that optimum oral hygiene level as well as the positive cooperation of the patient enhanced the success of periodontal treatment results even in extremely severe periodontal destruction.

    Gingivitis and periodontitis are immunoinflammatory periodontal diseases characterized by chronic localized infections usually associated with insidious inflammation This narrative review discusses periodontal diseases and mechanisms influencing the immune response and autoimmunity in pediatric rheumatic diseases (PRD), particularly juvenile idiopathic arthritis (JIA), childhood-onset systemic lupus erythematosus (C-SLE) and juvenile dermatomyositis (JDM). Gingivitis was more frequently observed in these diseases compared to health controls, whereas periodontitis was a rare finding. In JIA patients, gingivitis and periodontitis were related to mechanical factors, chronic arthritis with functional disability, dysregulation of the immunoinflammatory response, diet and drugs, mainly corticosteroids and cyclosporine. In C-SLE, gingivitis was associated with longer disease period, high doses of corticosteroids, B-cell hyperactivation and immunoglobulin G elevation. There are scarce data on periodontal diseases in JDM population, and a unique gingival pattern, characterized by gingival erythema, capillary dilation and bush-loop formation, was observed in active patients. In conclusion, gingivitis was the most common periodontal disease in PRD. The observed association with disease activity reinforces the need for future studies to determine if resolution of this complication will influence disease course or severity.

    To investigate the association between socioeconomic position and periodontal diseases among adolescents. Data were obtained from 9203 Chilean high school students. Clinical examinations included direct recordings of clinical attachment level and the necrotizing ulcerative gingival lesions. Students answered a questionnaire on various dimensions of socioeconomic position. Seven periodontal outcomes were analyzed. Logistic regression analyses were used to identify socioeconomic variables associated with the periodontal outcomes. The occurrence of all periodontal outcomes investigated followed social gradients, and paternal income and parental education were the most influential variables. The study demonstrates the existence of significant social gradients in periodontal diseases already among adolescents. This is worrying, and indicates a new potential for further insight into the mechanisms of periodontal disease causation.

    Full Text Available It is now well established that tobacco use in general and cigarette smoking in particular, is a major risk factor in the incidence and severity of several forms of periodontal diseases.A large number of studies have been published in the dental literature regarding this possible role. Much of the literature has also indicated that smokers affected with periodontitis respond less favourably to periodontal treatment be it non-surgical, surgical or regenerative. Numerous studies of the potential mechanisms whereby smoking tobacco may predispose to periodontal disease have been conducted, and it appears that smoking may affect the vasculature, the humoral immune system, and the cellular immune and inflammatory systems, and have effects throughout the cytokine and adhesion molecule network. The aim of this review is to consider the evidence for the association between smoking and periodontal diseases and to highlight the biological mechanisms whereby smoking may affect the periodontium.

    Periodontitis is driven by disproportionate host inflammatory immune responses induced by an imbalance in the composition of oral bacteria; this instigates microbial dysbiosis, along with failed resolution of the chronic destructive inflammation. The objectives of this study were to identify microbial signatures for health and chronic periodontitis at the genus level and to propose a model of dysbiosis, including the calculation of bacterial ratios. Published sequencing data obtained from several different studies (196 subgingival samples from patients with chronic periodontitis and 422 subgingival samples from healthy subjects) were pooled and subjected to a new microbiota analysis using the same Visualization and Analysis of Microbial Population Structures (VAMPS) pipeline, to identify microbiota specific to health and disease. Microbiota were visualized using CoNet and Cytoscape. Dysbiosis ratios, defined as the percentage of genera associated with disease relative to the percentage of genera associated with health, were calculated to distinguish disease from health. Correlations between the proposed dysbiosis ratio and the periodontal pocket depth were tested with a different set of data obtained from a recent study, to confirm the relevance of the ratio as a potential indicator of dysbiosis. Beta diversity showed significant clustering of periodontitis-associated microbiota, at the genus level, according to the clinical status and independent of the methods used. Specific genera ( Veillonella , Neisseria , Rothia , Corynebacterium , and Actinomyces ) were highly prevalent (>95%) in health, while other genera ( Eubacterium , Campylobacter , Treponema , and Tannerella ) were associated with chronic periodontitis. The calculation of dysbiosis ratios based on the relative abundance of the genera found in health versus periodontitis was tested. Nonperiodontitis samples were significantly identifiable by low ratios, compared to chronic periodontitis samples. When

    Periodontal disease (periodontitis) is a chronic inflammatory condition initiated by microbial infection that leads to gingival tissue destruction and alveolar bone resorption. The periodontal tissue's response to dental plaque is characterized by the accumulation of polymorphonuclear leukocytes, macrophages, and lymphocytes, all of which release inflammatory mediators and cytokines to orchestrate the immunopathogenesis of periodontal disease. Ubiquitination is achieved by a mechanism that involves a number of factors, including an ubiquitin-activating enzyme, ubiquitin-conjugating enzyme, and ubiquitin-protein ligase. Ubiquitination is a post-translational modification restricted to eukaryotes that are involved in essential host processes. The ubiquitin system has been implicated in the immune response, development, and programmed cell death. Increasing numbers of recent reports have provided evidence that many approaches are delivering promising reports for discovering the relationship between ubiquitination and periodontal disease. The scope of this review was to investigate recent progress in the discovery of ubiquitinated protein in diseased periodontium and to discuss the ubiquitination process in periodontal diseases.

    Glycosylated haemoglobin (HbA1c) level can consequently be interpreted as an average of the blood glucose present over the past 3-4 months. Periodontitis is associated with glycemic control in patients with diabetes. The purpose of this study was to determine the level of HbA1c in healthy and periodontitis patients who were previously not diagnosed with diabetes mellitus. A total of 40 patients were selected for study and divided into two groups. Group 1 included patients with a healthy periodontium, and Group 2 included patients suffering from chronic periodontitis. Finger stick blood was collected by special collection unit (A1CNOW+® Bayer Health Care, Tarrytown New York, USA), for estimating level of HbA1c. Both groups showed similar HbA1c levels clinically with slight increase in levels in the test group, but was statistically significant (test--5.66 ± 0.35%, control--5.17 ± 0.3% P = 0.003). Indians are at a high-risk of developing periodontitis and diabetes. These data suggest a possible link between periodontitis and glycemic control in nondiabetic individuals, periodontal disease may be a potential contributor to the development of type 2 diabetes.

    2015-01-01

    Studies suggest that periodontal disease, a source of subclinical and persistent infection, may be associated with various systemic conditions, including liver cirrhosis. The aim of this study was to examine the literature and determine the relationship between periodontal disease and liver cirrhosis and to identify opportunities and directions for future research in this area. A systematic review of English articles in the PubMed, EMBASE, and Scopus databases was conducted using search terms including 'liver cirrhosis', 'end-stage liver disease', 'liver diseases', 'oral health', 'periodontal disease', 'mouth disease', 'gingivitis', and 'periodontitis'. Thirteen studies published between 1981 and 2014 were found to include data on oral health and periodontal disease in cirrhotic patients. Studies indicated an increased incidence of periodontal disease in patients with liver cirrhosis, measured with several different periodontal indices. The reported prevalence of periodontal disease in cirrhosis patients ranged from 25.0% to 68.75% in four studies and apical periodontitis was found in 49%-79% of the patients. One study found that mortality was lower among patients who underwent dental treatment versus non-treated patients. Another study suggested an association between periodontal disease and the progression of liver cirrhosis, but data are sparse and conflicting as to whether periodontal disease is correlated to cirrhosis aetiology and severity. Despite the clinical reality of periodontal disease in liver cirrhosis patients, there are few published studies. Before clinical implications can be addressed, more data on the prevalence of and correlation between periodontal disease and liver cirrhosis aetiology, duration, and progression are needed.

    C-reactive protein (CRP) is an acute-phase reactant and has been proved to be a significant predictor of future cardiovascular events. Recent studies have demonstrated a correlation between periodontitis and elevated CRP levels. However, most of the studies have focused on chronic periodontitis and very few studies are done in patients with aggressive periodontitis. The aim of this study was to determine and compare the relative levels of serum CRP in aggressive and chronic periodontitis patients. A total of 75 systemically healthy subjects were divided into three groups: Group I, nonperiodontitis subjects; group II, chronic generalized periodontitis patients and group III, generalized aggressive periodontitis patients. All participants were subjected to quantitative CRP analysis using enzyme-linked immunosorbent assay. Mean CRP levels were significantly greater in both group II and III as compared to group I and group III having greater level than group II. Furthermore, CRP levels positively correlated with the amount of periodontal destruction as measured by probing depth and clinical attachment loss. The present study indicates a positive correlation between CRP and periodontal disease severity with particular concern in younger individuals that could be a possible underlying pathway in the association between periodontal disease and the observed higher risk for cardiovascular disease in periodontitis patients.

  4. Pathogenesis of apical periodontitis and the causes of endodontic failures.

    Nair, P N R

    2004-11-01

    Apical periodontitis is a sequel to endodontic infection and manifests itself as the host defense response to microbial challenge emanating from the root canal system. It is viewed as a dynamic encounter between microbial factors and host defenses at the interface between infected radicular pulp and periodontal ligament that results in local inflammation, resorption of hard tissues, destruction of other periapical tissues, and eventual formation of various histopathological categories of apical periodontitis, commonly referred to as periapical lesions. The treatment of apical periodontitis, as a disease of root canal infection, consists of eradicating microbes or substantially reducing the microbial load from the root canal and preventing re-infection by orthograde root filling. The treatment has a remarkably high degree of success. Nevertheless, endodontic treatment can fail. Most failures occur when treatment procedures, mostly of a technical nature, have not reached a satisfactory standard for the control and elimination of infection. Even when the highest standards and the most careful procedures are followed, failures still occur. This is because there are root canal regions that cannot be cleaned and obturated with existing equipments, materials, and techniques, and thus, infection can persist. In very rare cases, there are also factors located within the inflamed periapical tissue that can interfere with post-treatment healing of the lesion. The data on the biological causes of endodontic failures are recent and scattered in various journals. This communication is meant to provide a comprehensive overview of the etio-pathogenesis of apical periodontitis and the causes of failed endodontic treatments that can be visualized in radiographs as asymptomatic post-treatment periapical radiolucencies.

    2013-03-01

    Commonly used terms such as "supportive care," "best supportive care," "palliative care," and "hospice care" were rarely and inconsistently defined in the palliative oncology literature. We conducted a systematic review of the literature to further identify concepts and definitions for these terms. We searched MEDLINE, PsycInfo, EMBASE, and CINAHL for published peer-reviewed articles from 1948 to 2011 that conceptualized, defined, or examined these terms. Two researchers independently reviewed each citation for inclusion and then extracted the concepts/definitions when available. Dictionaries/textbooks were also searched. Nine of 32 "SC/BSC," 25 of 182 "PC," and 12 of 42 "HC" articles focused on providing a conceptual framework/definition. Common concepts for all three terms were symptom control and quality-of-life for patients with life-limiting illness. "SC" focused more on patients on active treatment compared to other categories (9/9 vs. 8/37) and less often involved interdisciplinary care (4/9 vs. 31/37). In contrast, "HC" focused more on volunteers (6/12 vs. 6/34), bereavement care (9/12 vs. 7/34), and community care (9/12 vs. 6/34). Both "PC" and "SC/BSC" were applicable earlier in the disease trajectory (16/34 vs. 0/9). We found 13, 24, and 17 different definitions for "SC/BSC," "PC," and "HC," respectively. "SC/BSC" was the most variably defined, ranging from symptom management during cancer therapy to survivorship care. Dictionaries/textbooks showed similar findings. We identified defining concepts for "SC/BSC," "PC," and "HC" and developed a preliminary conceptual framework unifying these terms along the continuum of care to help build consensus toward standardized definitions.

    Full Text Available Background. Proinflammatory and anti-inflammatory cytokines play a key role in the pathogenesis of periodontal diseases. Secretion of bioactive IL-35 has been described by T regulatory cells ( and is required for their maximal suppressive activity. are involved in the modulation of local immune response in chronic periodontitis patients. Objective. Hence, the present study was aimed to investigate the expression of IL-35 mRNA in chronic periodontitis and aggressive periodontitis patients. Materials and Methods. The present study was carried out in 60 subjects, which included 20 chronic periodontitis patients, 20 aggressive periodontitis patients, and 20 periodontally healthy controls. IL-35 mRNA expression in gingival tissue samples of all subjects was semiquantitatively analyzed using Reverse Transcriptase Polymerase Chain Reaction (RT-PCR. Results. The present study demonstrated the expression of IL-35 mRNA in gingival tissues of all the three groups. IL-35 mRNA expression was highest in chronic periodontitis subjects ( as compared to the aggressive periodontitis group ( and least seen in healthy patients (. Conclusion. The increased expression of IL-35 in chronic and aggressive periodontitis suggests its possible role in pathogenesis of periodontitis. Future studies done on large samples with intervention will strengthen our result.

    Data on whether periodontal therapy affects serum CRP levels are inconclusive. The aim of this study was to determine if nonsurgical periodontal therapy has any effect on CRP and serum lipid levels in patients with advanced periodontitis. Thirty-six systemically healthy patients, ≥ 40 years of age and with advanced periodontitis, were recruited for the study. Patients were randomized consecutively to one of two groups: the treatment group (n = 18) or the control group (n = 18). Treated subjects received nonsurgical periodontal therapy, which included oral hygiene instructions and subgingival scaling and root planing. Systemic levels of inflammatory markers [C-reactive protein (CRP) and the lipid profile] were measured at baseline and 3 mo after periodontal therapy. Nonsurgical periodontal therapy in the treatment group resulted in a significant reduction in the serum CRP level. The average CRP level decreased from 2.3 mg/dL at baseline to 1.8 mg/dL (p periodontal therapy. The average reduction (95% confidence interval) in CRP was 0.498 (95% confidence interval = 0.265-0.731). In the treatment group, the reduction in CRP was significantly, linearly and directly correlated with the reduction in the plaque index, the gingival index and the percentage of sites with pocket depth ≥ 7 mm (Pearson correlation coefficient = 0.746, 0.425 and 0.621, respectively). Nonsurgical periodontal therapy had no effect on the lipid parameters. This study demonstrated that nonsurgical periodontal therapy results in a significant reduction in the serum CRP level. The effect of this outcome on systemic disease is still unknown. © 2011 John Wiley & Sons A/S.

    Full Text Available Background: Periodontal disease, commonly known as periodontitis is an infectious disease which has multifactorial etiologic factors. It may affect everybody in any ages with no gender nor sex predilection and usually can be detected under routine clinical examination. This disease is a manifestation of local factors, host factor and environmental factors, resulting in periodontal tissue damage which may cause tooth mobility and tooth loss. Interleukin-1 is a pro-inflammatory protein which functions primarily as inflammatory mediator in host innate immune responses. IL-1 is a regulator, affecting many biological activities including proliferation, development, homeostasis, regeneration, repair and inflammation which contribute to tissue damage and alveolar bone resorption. Purpose: This research was aimed to reveal the basic pathogenesis of periodontitis and could determine the future definitive treatment for patients with periodontitis. Methods: Data were obtained from 40 patients with aggressive periodontitis and 40 patients with chronic periodontitis. Samples were collected from periodontal tissue patients and protein expression of IL-1β was performed with immunohistochemistry. Results: Most female patient suffer aggressive periodontitis and chronic periodontitis. The datas were analyzed with t-test. The t values result was -8623, significance 0.001, with α = 5%, which indicated there was significant difference in IL-1β expression between aggressive and chronic periodontitis. The box plot diagram showed marked difference in distribution of protein expression of IL-1β between patients with aggressive periodontitis and chronic periodontitis. With a regression equation, it might be concluded that the protein expression of IL-1β might affect the incidence of aggressive periodontitis and chronic periodontitis. The OR value was calculated for 0.746 (sign.= 0.001, which indicate each increment of one unit protein expression of IL-1β will lead

    On December 19, 2003, the Centers for Disease Control and Prevention released the Guidelines for Infection Control in Dental Health-Care Settings--2003. The publication was the first comprehensive dental infection control update since 1993. Although the guidelines are not directed toward a particular dental specialty, some recommendations may have a significant impact on the practice of periodontics because of the nature of the procedures that are considered routine to the specialty. This article deals with some of the issues addressed in the guidelines, highlighting topics of special interest to periodontists.

    Porphyromonas gingivalis is considered a critical pathogen of periodontal diseases including recurrent periodontitis. The profound effects of active periodontal treatment (APT) on P. gingivalis elimination were previously demonstrated and revealed that the subsequent P. gingivalis-free or -suppressed status seems to be maintained during early periodontal maintenance (PMT). The aim of the present study was to show the occurrence of microbial recolonization during this early PMT period. In total, 128 sites from 11 generalized chronic periodontitis patients and one generalized aggressive periodontitis patient underwent clinical and microbiologic examination at baseline (Exam-I), after APT (Exam-II), and in PMT (Exam-III). Exam-III was carried out an average of 4.5 +/- 3.5 months after Exam-II. Detection and quantification of putative pathogens were performed using a polymerase chain reaction-based method. The PMT used was effective in maintaining the clinical conditions improved by APT. However, in microbiological examinations, Exam-III showed higher detection frequency and levels of P. gingivalis than Exam-II. This suggests that a P. gingivalis recolonization started in the early PMT period. P. gingivalis-increased sites then showed significantly more severe signs of periodontitis in Exam-I than P. gingivalis-stable sites (bleeding on probing frequency: 76.7% versus 56.5%; suppuration frequency: 41.9% versus 12.9%). On the other hand, in Exam-II, no significant differences of clinical parameters were noted between P. gingivalis-increased and -stable sites. Severe periodontitis sites before APT seemed to place them at risk of P. gingivalis recolonization in the early PMT period, and this microbial restoration could be a cause of recurrent periodontitis.

    Multidisciplinary therapy is essential in dental practice to achieve optimized outcomes. The present case report describes the application of periodontal surgery with a five-year follow-up in a patient with malocclusion and chronic periodontitis. In the presence of periodontal inflammation, orthodontic therapy may result in further periodontal breakdown due to plaque accumulation. In order to prevent this progression, scaling and root planning with a periodontal endoscope was applied, and continuous clinical monitoring and risk assessment was performed every 3 months using a Florida Probe. This combined treatment supports the long-term maintenance of periodontal conditions, functional occlusion and harmony of the facial profile.

    The incidence and progression of the periodontal disease depend on periodontal microflora and the multifaceted response of the host, and these interactions are mediated by cytokines and chemokines. Interleukin-18 (IL-18) is a proinflammatory cytokine of the IL-1 superfamily. The aim of the present study was the assessment of the periodontal therapy in IL-18 level in periodontal disease and health. Based on clinical attachment loss (CAL), probing pocket depth (PPD), gingival index (GI), and plaque index (PI) patients were divided into three groups: Group I with healthy patients, group II with chronic periodontitis, and group III with posttreatment patients having periodontitis. Mean PI, PPD, CAL, and gingival crevicular fluid (GCF) volume were significantly higher in groups II and III compared with group I. However, there were no significant differences between GI in groups I, II, and III. The total amount of IL-18 in GCF was significantly higher in group II when compared with groups I and III (p periodontally involved patients, and reduced at baseline, 3 and 6 weeks after nonsurgical periodontal therapy. The IL-18 might be hypothetically beneficial in distinguishing health from disease and monitoring periodontal disease activity.

    Full Text Available Periodontal disease (PD and atherosclerosis are both polymicrobial and multifactorial and although observational studies supported the association, the causative relationship between these two diseases is not yet established. Polymicrobial infection-induced periodontal disease is postulated to accelerate atherosclerotic plaque growth by enhancing atherosclerotic risk factors of orally infected Apolipoprotein E deficient (ApoE(null mice. At 16 weeks of infection, samples of blood, mandible, maxilla, aorta, heart, spleen, and liver were collected, analyzed for bacterial genomic DNA, immune response, inflammation, alveolar bone loss, serum inflammatory marker, atherosclerosis risk factors, and aortic atherosclerosis. PCR analysis of polymicrobial-infected (Porphyromonas gingivalis [P. gingivalis], Treponema denticola [T. denticola], and Tannerella forsythia [T. forsythia] mice resulted in detection of bacterial genomic DNA in oral plaque samples indicating colonization of the oral cavity by all three species. Fluorescent in situ hybridization detected P. gingivalis and T. denticola within gingival tissues of infected mice and morphometric analysis showed an increase in palatal alveolar bone loss (p<0.0001 and intrabony defects suggesting development of periodontal disease in this model. Polymicrobial-infected mice also showed an increase in aortic plaque area (p<0.05 with macrophage accumulation, enhanced serum amyloid A, and increased serum cholesterol and triglycerides. A systemic infection was indicated by the detection of bacterial genomic DNA in the aorta and liver of infected mice and elevated levels of bacterial specific IgG antibodies (p<0.0001. This study was a unique effort to understand the effects of a polymicrobial infection with P. gingivalis, T. denticola and T. forsythia on periodontal disease and associated atherosclerosis in ApoE(null mice.

    This study was conducted to reveal phenotypic, serological subtypes and antibiotic susceptibility among fresh isolates of Porphyromonas gingivalis in a Swedish population with periodontitis and periodontal abscess. Fifty-five subgingival strains were isolated and tentatively designated as P. gingivalis from 55 consecutive paper-point samples taken from 51 patients with periodontitis (at least one site with >6-mm pocket depth) in Sweden and were sent in for microbiological evaluation. Eight P. gingivalis strains from periodontal abscesses were also included. Four P. gingivalis strains served as reference and another four type strains were included. The strains were characterized by colony morphology, biochemical tests, enzyme profile, gas-liquid chromatography and antibiotic susceptibility. The strains were further characterized for whole cell protein profiles using sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and were identified to serotype by specific monoclonal antibodies. Among the 55 P. gingivalis strains 35 had smooth (S), 13 rough (R) and seven semi-rough colony morphologies. All strains were phenotypically homogeneous in biochemical tests, enzyme profile and antibiotic susceptibility. All strains produced phenylacetic acid and alpha-fucosidase. Almost all (96%) of the subgingival strains, but relatively fewer (62%) of the abscess strains, belonged to serotype A. Two subgingival and three abscess strains were classified as serotype B. No specific SDS-PAGE protein profiles were recorded for the two serotypes. The P. gingivalis strains from Swedish periodontitis cases showed homogeneity in terms of biochemical phenotypes and antibiotic susceptibility patterns. The strains fell into two serotypes, of which serotype A predominated in the periodontitis cases and serotype B was overrepresented in periodontal abscesses.

    , results of comparable trials were pooled and expressed as risk ratios (RR) or mean differences (MD) with 95% confidence intervals (CI) . The random-effects model was used for pooling except where there was an insufficient number of studies. We assessed the quality of the evidence using GRADE. There were 15 RCTs (n = 7161 participants) meeting our inclusion criteria. All the included studies were at high risk of bias mostly due to lack of blinding and imbalance in baseline characteristics of participants. The studies recruited pregnant women from prenatal care facilities who had periodontitis (14 studies) or gingivitis (1 study).The two main comparisons were: periodontal treatment versus no treatment during pregnancy and periodontal treatment versus alternative periodontal treatment. The head-to-head comparison between periodontal treatments assessed a more intensive treatment versus a less intensive one.Eleven studies compared periodontal treatment with no treatment during pregnancy. The meta-analysis shows no clear difference in preterm birth birth weight birth birth weight birth) (RR 0.85, 95% CI 0.51 to 1.43; 5320 participants; 7 studies; very low-quality evidence), and pre-eclampsia (RR 1.10, 95% CI 0.74 to 1.62; 2946 participants; 3 studies; very low-quality evidence). There is no evidence of a difference in small for gestational age (RR 0.97, 95% CI 0.81 to 1.16; 3610 participants; 3 studies; low-quality evidence) when periodontal treatment is compared with no treatment.Four studies compared periodontal treatment with alternative periodontal treatment.

    Radiographs are a well-accepted tool in diagnosing periodontal bone lesions and making an accurate evaluation of the treatment. However, the assessment of bone is hampered by the complicated and as it were unpredictable pattern of bone structure. Therefore, and to compensate for the bias always present in human observations, a computer aided procedure was developed to detect and describe periodontal bone lesions. This paper describes a comparison of the performance by human observers and of the computer program. Two series of artificial periodontal bone lesions served as material for the assessments. This study shows that the automated lesion detection program enables an assessment of periodontal bone lesions, which is at least comparable with the results of a group of experienced observers and probably better. It is considerably better than the results of observers individually, and decreases the time-dependent variability appearing in repeated assessments of a single observer. The computer aided detection of periodontal lesions can be considered as a useful and reliable tool in periodontal diagnosis. 9 ref.; 2 figs

    Many middle aged and old persons take periodontal diseases that mainly cause teeth loss and result in some systemic diseases. The prevention of periodontal diseases is very important for oral and systemic health, but the present diagnostic examination is not fully objective and suitable. To diagnose periodontal diseases exactly, some biomarkers shown inflammation, tissue degradation and bone resorption, in gingival crevicular fluid (GCF) and saliva are known. We demonstrated that GCF levels of calprotectin, inflammation-related protein, and carboxy-terminal propeptide of type I procollagen, bone metabolism-related protein, were associated with clinical condition of periodontal diseases, and suggested that these proteins may be useful biomarkers for periodontal diseases. Recently, determinations of genes and proteins by using microdevices are studied for diagnosis of some diseases. We detected calprotectin protein by chemiluminescent immunoassay on a microchip and showed the possibility of specific and quantitative detection of calprotectin in a very small amount of GCF. To determine plural markers in GCF by using microdevices contributes to develop accurate, objective diagnostic system of periodontal diseases.

    Periodontal disease, a relevant public health problem worldwide, is generally considered a common pathology of elderly people. In this respect, there is agreement about that nutritional status may be a modifying factor in the progression and healing of the periodontal tissues. Vitamins have been recommended as nutraceuticals for prevention and treatment of some pathological conditions, such as cardiovascular diseases, obesity or cancer. Thus, a systematic approach to determining how the different vitamin type could ameliorate periodontal risks or improve periodontal health is necessary to further the understanding of the potential benefits and risks of vitamins supplementation use. For this, a systematic review of English-written literature in PubMed until February 2018, which included both human and animal research on the relationship of each vitamin with periodontal disease, was conducted. Among all the analyzed vitamins those with antioxidant capacity and effects on immune system seem to be useful for prevention or improvement of periodontal disease, as well as those implicated in bone metabolism. In the first case, there are quite information in favor of various vitamins, mainly vitamin C, that is the most studied. In the second case, vitamin D seems to have the most relevant role.

    Full Text Available Animal models and cell cultures have contributed new knowledge in biological sciences, including periodontology. Although cultured cells can be used to study physiological processes that occur during the pathogenesis of periodontitis, the complex host response fundamentally responsible for this disease cannot be reproduced in vitro. Among the animal kingdom, rodents, rabbits, pigs, dogs, and nonhuman primates have been used to model human periodontitis, each with advantages and disadvantages. Periodontitis commonly has been induced by placing a bacterial plaque retentive ligature in the gingival sulcus around the molar teeth. In addition, alveolar bone loss has been induced by inoculation or injection of human oral bacteria (e.g., Porphyromonas gingivalis in different animal models. While animal models have provided a wide range of important data, it is sometimes difficult to determine whether the findings are applicable to humans. In addition, variability in host responses to bacterial infection among individuals contributes significantly to the expression of periodontal diseases. A practical and highly reproducible model that truly mimics the natural pathogenesis of human periodontal disease has yet to be developed.

    Pustulosis palmaris et plantaris (PPP) is a chronic, inflammatory, autoimmune-type disease characterized by sterile pustules of skin. The skin inflammation is influenced by several factors such as drugs, sunlight, metabolic and psychogenic factors as well as metal allergy. Here, we report a rare case that intensive periodontal treatment might have contributed to the improvement of skin inflammation. Skin inflammation regressed 1 month after intensive periodontal treatment. Both CD4/CD8 ratio and % of B cells in the blood sample were slightly decreased corresponding to the improvement of periodontal inflammation. Infection control of periodontal lesions might be one of attractive therapeutic targets in management of PPP.

    In this study, we aimed to investigate the efficacy of combined orthodontic-periodontic treatment in the treatment of patients with periodontitis and its effects on the levels of inflammatory cytokines. A total of 117 patients with periodontitis were randomly assigned to the basic group (receiving basic periodontic treatment, n = 58) and the combined group (receiving combined orthodontic-periodontic treatment, n = 59). In addition, 52 healthy people without periodontal disease were selected as the normal group. Probing depth, tooth mobility, plaque index, clinical attachment level, and sulcus bleeding index were recorded. ELISA was applied to detect gingival crevicular fluid (GCF) and serum levels of inflammatory cytokines. A 2-year clinical follow-up was conducted. Before treatment, the periodontal parameters (probing depth, tooth mobility, plaque index, clinical attachement level, and sulcus bleeding index) and GCF and serum levels of inflammatory cytokines (high-sensitivity C-reactive protein, interleukin-1β, interleukin-5, interleukin-6, interleukin-8, tumor necrosis factor-α, and prostaglandin E2) in the combined and basic groups were higher than those in the normal group. After 6 and 18 months of treatment, the periodontal parameters and GCF and serum levels of inflammatory cytokines decreased in the combined and basic groups. The periodontal parameters and the GCF and serum levels of inflammatory cytokines in the combined group were significantly lower than those in the basic group after 18 months of treatment. The combined group had a lower recurrence rate compared with the basic group. Combined orthodontic-periodontic treatment had good clinical efficacy in the treatment of periodontitis and could effectively decrease the levels of inflammatory cytokines.

    Periodontal ligament (PDL) is a specialized connective tissue that connects cementum and alveolar bone to maintain and support the teeth in situ and preserve tissue homeostasis. Recent studies have revealed the existence of stem cells in human dental tissues including periodontal ligament that play an important role, not only in the maintenance of the periodontium but also in promoting periodontal regeneration. In this study, human periodontal ligament cells (hPDLCs) were isolated by outgrowth and enzymatic dissociation methods. Expression of surface markers on PDLCs as human mesenchymal stem cells (MSCs) was identified by flow cytometry. In addition, proliferation and differentiation capacity of cultured cells to osteoblasts, adipocytes were evaluated. As a result, we successfully cultured cells from the human periodontal ligament tissues. PDLCs express mesenchymal stem cell (MSC) markers such as CD44, CD73, and CD90 and do not express CD34, CD45, and HLA-DR. PDLCs also possess the multipotential to differentiate into various types of cells, such as osteoblast and adipocytes, in vitro. Therefore, these cells have high potential to serve as materials for tissue engineering, especially dental tissue engineering.

    Clear aligner treatment (CAT) has been cited as a safe and comfortable orthodontic procedure for adult patients. However, the available evidence is scarce. To perform a systematic review of the existing literature in order to assess periodontal health during CAT. Pubmed, Pubmed Central, National Library of Medicine's Medline, Embase, Cochrane Central Register of Controlled Clinical trials, Web of Knowledge, Scopus, Google Scholar, and LILACS were searched from January 1945 to September 2014 to identify all peer-reviewed papers potentially relevant to the review. After duplicate selection and extraction procedures, the risk of bias was assessed according to the Centre for Reviews and Dissemination criteria, and a 3-point grading system, as described by the Swedish Council on Technology Assessment in Health Care (SBU), was used to rate the methodological quality of the selected papers. A PICOS table was used for data extraction. Five relevant articles were selected from the 1247 identified articles. The level of evidence was moderate for all the studies. A significant improvement of the periodontal health indexes was revealed, in particular when CAT was compared to fixed appliances. No periodontal CAT adverse effects were observed in the selected studies. Periodontal health indexes were significantly improved during CAT. The results of this review should be interpreted with some caution because of the number, quality, and heterogeneity of the included studies. © The Author 2014.

    Reactive oxygen species (ROS) are products of normal cellular metabolism. However, excessive production of ROS oxidizes DNA, lipids and proteins, inducing tissue damage. Studies have shown that periodontitis induces excessive ROS production in periodontal tissue. When periodontitis develops, ROS produced in the periodontal lesion diffuse into the blood stream, resulting in the oxidation of blood molecules (circulating oxidative stress).

    Aim This study compared the subgingival microbiota of subjects with refractory periodontitis (RP) to those in subjects with treatable periodontitis (GR) or periodontal health (PH) using the Human Oral Microbe Identification Microarray (HOMIM). Methods At baseline, subgingival plaque samples were taken from 47 periodontitis and 20 PH individuals, and analyzed for the presence of 300 species by HOMIM. The periodontitis subjects were classified as RP (n=17) based on mean attachment loss (AL) and/or >3 sites with AL ≥2.5 mm after SRP, surgery and systemically administered amoxicillin and metronidazole or as GR (n=30) based on mean attachment gain and no sites with AL ≥2.5 mm after treatment. Significant differences in taxa among groups were sought using the Kruskal Wallis and Chi-square tests. Results More species were detected in diseased patients (GR or RP) than those without disease (PH). RP subjects were distinguished from GR and PH by a significantly high frequency of putative periodontal pathogens such as, Parvimonas micra, Campylobacter gracilis, Eubacterium nodatum, Selenomonas noxia, Tannerella forsythia, Porphyromonas gingivalis, Prevotella spp., Treponema spp., Eikenella corrodens, as well as “unusual” species (Pseudoramibacter alactolyticus, TM7 spp. oral taxon (OT) 346/356, Bacteroidetes spp. OT 272/274, Solobacterium moorei, Desulfobulbus sp.

    Full Text Available ABSTRACT   Introduction: Periodontitis is an inflammatory disease that attacks the periodontal tissue comprises the gingiva, periodontal ligament, cementum and alveolar bone caused mainly by plaque bacteriophage or other specific dominant type of bacteria. The purpose of this study was to determine the therapeutic effect of clinical application of mangosteen peel extract gel as adjunctive therapy scaling and root planing in patients with chronic periodontitis. This research was expected to developed new treatment in the field of dentistry, particularly in periodontics, which can be used as supporting material for the treatment of chronic periodontitis. Methods: Quasi-experimental research, split mouth, with as many as 14 chronic periodontitis patients. Mangosteen rind was prepared to be formed into extract gel, dried at room temperature, then the dried samples were macerated by using ethanol, then evaporated and decanted for 3 days until obtained condensed extract. The samples were patients with chronic periodontitis in at least 2 teeth with pockets ≥ 5 mm. Clinical parameters of pocket depth, gingival bleeding, and clinical epithelial attachment level were measured at baseline and 1 month after treatment. Analysis of data using the t-test. Results: The comparison of average gap ratio of pockets depth, gingival index, gingival bleeding and epithelium attachment levels, before and after treatment showed significant differences, such as in the test and control sides. Conclusion: The mangosteen rind gel as adjunctive therapy for scaling and root planing is able to reduce pockets depth, gingival index, and gingival bleeding, and improve clinical epithelial attachment.

    This study was conducted to compare periodontal therapy outcomes during pregnancy and after delivery. One hundred nine pregnant women up to the 20th gestational week (GW) were randomized into two groups: the test group (comprehensive periodontal therapy during pregnancy) and the control group (comprehensive periodontal therapy after delivery). Periodontal examinations comprised plaque index (PI), gingival index (GI), periodontal probing depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP), and gingival crevicular fluid (GCF) volume. After baseline examination, women in the test group received periodontal treatment up to the 24th GW. The final examination was performed at the 26th to the 28th GW. Women in the control group were treated 30 days after delivery and reexamined 30 days after treatment. Periodontal therapy significantly reduced periodontal inflammation in both groups. The mean percentage of sites with BOP was reduced from 49.14 % (±22.49) to 11.10 % (±7.84) and from 45.71 % (±17.86) to 8.07 % (±5.21) in the test and control groups, respectively (p = 0.95). No statistically significant differences were observed between groups concerning PI, GI, PPD, CAL, and GCF. The reduction in mean percentage of sites with BOP stratified for initial PPD ≥4 mm was higher in the control group (p pregnancy do not interfere in treatment outcomes in women with widespread gingival inflammation and limited periodontal destruction. The role of these hormonal changes in pregnant women with different disease patterns remains uncertain. Periodontal health can be reestablished irrespective of the hormonal challenge that takes place during pregnancy.

    Despite clinical trials and reviews attempt to assess a possible relationship between dementia and periodontal disease, no meta-analysis has been performed and this issue remains undetermined. The aim of this study is to conduct a systematic review and meta-analysis to assess severity of periodontitis in subjects with dementia. The search was conducted in Pubmed, Embase/MEDLINE. Two independent reviewers extracted data and assessed the risk bias (Newcastle-Ottawa scale). Meta-analyses were performed using the means of probing depth (PD) and clinical attachment loss (CAL) in patients with or without dementia. The mean difference were analyzed (P ≤ 0.05). Fourteen studies were included in the systematic review. In the qualitative analysis, most studies reported higher prevalence of periodontal disease in dementia patients. The studies had low risk of bias and two meta-analyses were performed for each parameter, including or not a cross-sectional study. The meta-analyses including the cross-sectional study demonstrated significant association between dementia and periodontal disease (mean difference: PD = 1.41; CAL = 1.40, P periodontal conditions in dementia patients, due to different study types and the high heterogeneity among them, the meta-analysis does not support the association between dementia and severity of periodontal disease.

    Gene therapy is a field of Biomedicine. With the advent of gene therapy in dentistry, significant progress has been made in the control of periodontal diseases and reconstruction of dento-alveolar apparatus. Implementation in periodontics include: -As a mode of tissue engineering with three approaches: cell, protein-based and gene delivery approach. -Genetic approach to Biofilm Antibiotic Resistance. Future strategies of gene therapy in preventing periodontal diseases: -Enhances host defense mechanism against infection by transfecting host cells with an antimicrobial peptide protein-encoding gene. -Periodontal vaccination. Gene therapy is one of the recent entrants and its applications in the field of periodontics are reviewed in general here. PMID:20376232

    The aim of our study was to assess the subgingival profile of 9 periodontal pathogens, by means of real-time PCR, in a group of predialysis chronic kidney disease patients with and without periodontal disease and to identify the risk factors associated with periodontal disease in these patients. This is a single centre cross-sectional cohort study performed on 70 CKD patients. Patients received a full-mouth periodontal examination and the following parameters were assessed: periodontal pocket depth (PPD), clinical attachment level, bleeding on probing, and plaque index; subgingival biofilm samples were collected from the deepest periodontal pocket of each quadrant and were pooled in one transporting unit. Clinical data were drawn from the medical file of the patients. T. denticola (P = 0.001), T. forsythia (P < 0.001), and P. micros (P = 0.003) are significantly associated with periodontal disease in CKD subjects but in a multivariate model only age and T. forsythia remain independent risk factors for periodontal disease in patients with CKD. In our cohort, age and T. forsythia are independently associated with periodontitis in CKD patients. Within the limits of this study, CKD was not significantly associated with a particular subgingival periodontal pathogens profile in periodontitis patients.

    LL-37 contributes to maintaining the balance between health and disease. Smoking is a risk factor for periodontitis that impairs neutrophil functions. The aim of the present study was to comparatively evaluate gingival crevicular fluid (GCF) LL-37 levels in smoker and non-smoker chronic periodontitis (CP) patients and controls, as well as the effect of non-surgical periodontal treatment on GCF LL-37 levels. Thirty-one CP patients (16 smokers, 15 non-smokers) and thirty-one controls (16 smokers, 15 non-smokers) were included in the study. CP patients received non-surgical treatment. GCF LL-37 levels and periodontal parameters were assessed at baseline, 1 and 3 months after completion of non-surgical periodontal treatment. GCF LL-37 levels were analyzed by ELISA. No significant difference was observed in GCF LL-37 levels between smoker and non-smoker controls (p>0.05). Smoker CP group had significantly lower GCF LL-37 level than non-smoker CP group at baseline (pnon-smoker CP group at first week, 1 and 3 months after completion of non-surgical periodontal treatment (psmoker CP group (p>0.05). Periodontal parameters were correlated with GCF LL-37 levels in non-smoker CP group (psmoker CP group (p>0.05). GCF LL-37 levels do not seem to be affected from smoking in periodontal health. However, smoking might have a suppressive effect on GCF LL-37 levels in CP. Non-surgical treatment is effective in decreasing GCF LL-37 levels in non-smoker CP patients but not in smokers with CP.

  18. Periodontal disease and liver cirrhosis: A systematic review

    Science.gov (United States)

    2015-01-01

    Objectives: Studies suggest that periodontal disease, a source of subclinical and persistent infection, may be associated with various systemic conditions, including liver cirrhosis. The aim of this study was to examine the literature and determine the relationship between periodontal disease and liver cirrhosis and to identify opportunities and directions for future research in this area. Methods: A systematic review of English articles in the PubMed, EMBASE, and Scopus databases was conducted using search terms including ‘liver cirrhosis’, ‘end-stage liver disease’, ‘liver diseases’, ‘oral health’, ‘periodontal disease’, ‘mouth disease’, ‘gingivitis’, and ‘periodontitis’. Results: Thirteen studies published between 1981 and 2014 were found to include data on oral health and periodontal disease in cirrhotic patients. Studies indicated an increased incidence of periodontal disease in patients with liver cirrhosis, measured with several different periodontal indices. The reported prevalence of periodontal disease in cirrhosis patients ranged from 25.0% to 68.75% in four studies and apical periodontitis was found in 49%–79% of the patients. One study found that mortality was lower among patients who underwent dental treatment versus non-treated patients. Another study suggested an association between periodontal disease and the progression of liver cirrhosis, but data are sparse and conflicting as to whether periodontal disease is correlated to cirrhosis aetiology and severity. Conclusion: Despite the clinical reality of periodontal disease in liver cirrhosis patients, there are few published studies. Before clinical implications can be addressed, more data on the prevalence of and correlation between periodontal disease and liver cirrhosis aetiology, duration, and progression are needed.

    Homocysteine (Hcy) is implicated in the development of cardiovascular diseases (CVD). The effect of periodontal disease and periodontal therapy on plasma Hcy remains controversial. Hence, in this pilot study we assessed the effect of periodontal disease and non-surgical periodontal therapy (NSPT) on plasma Hcy in systemically healthy Indian subjects. Forty participants (30 to 39 years) were enrolled in the study and were divided into two groups based on gingival index, probing depth, and clinical attachment level (CAL): Healthy (control group; n = 20) and Chronic Periodontitis (test group; n = 20). Plasma samples were collected and quantified at baseline and 12 weeks after scaling and root planing (SRP) for Hcy using High Performance Liquid Chromatography with fluorescent detection (HPLC-fld). Plasma Hcy levels of chronic periodontitis (17.87 ± 1.21 μmol/l) subjects was significantly higher than healthy subjects (9.09 ± 2.11 μmol/l). Post-therapy, the plasma Hcy concentration reduced significantly (11.34 ± 1.87 μmol/l) (p periodontal inflammation and therapy, respectively, indicate a direct relationship of Hcy with chronic periodontitis.

    The rich bacterial flora of oral cavity is controlled by innate immune response, including antibacterial peptides and among them human neutrophil peptides 1-3 (HNP1-3). The knowledge of the involvement of HNPs in innate and acquired immunity of the periodontium is fragmentary. The aim of the study was to assess alterations in HNP1-3 levels in the gingival crevicular fluid (GCF) of chronic periodontitis patients before and after nonsurgical periodontal therapy. Nineteen patients with chronic periodontitis were qualified to the study. After periodontal examination, one site with pocket depth (PD) ≥4 mm was selected. All the patients received periodontal treatment involving scaling and root planing with additional systemic antibiotic therapy (Amoxicillin 375 mg three times daily and Metronidazole 250 mg three times daily for 7 days). Prior to therapy, 3 and 6 months after it, clinical periodontal parameters were measured and GCF was collected from previously chosen site. The level of HNP1-3 in GCF was determined by means of a commercially available enzyme-linked immunoassay kit. The periodontal therapy caused a statistically significant (p periodontal therapy with additional systemic administration of Amoxicillin and Metronidazole increases the level of HNP1-3 in GCF.

    Companion animal periodontal disease is one of the most prevalent diseases seen by veterinarians. The goal of this study was to evaluate the vaccine performance of a trivalent canine periodontitis vaccine in the mouse oral challenge model of periodontitis. Mice vaccinated subcutaneously with an inactivated, whole-cell vaccine preparation of Porphyromonas denticanis, Porphyromonas gulae, and Porphyromonas salivosa displayed significantly reduced alveolar bone loss in response to heterologous and cross-species challenges as compared to sham vaccinated animals. Based on the results of these studies, a periodontitis vaccine may be a useful tool in preventing the initiation and progression of periodontitis caused by the most commonly isolated pigmenting anaerobic bacteria in animals.

    Full Text Available Objective and Background: Glycosylated haemoglobin (HbA1c level can consequently be interpreted as an average of the blood glucose present over the past 3-4 months. Periodontitis is associated with glycemic control in patients with diabetes. The purpose of this study was to determine the level of HbA1c in healthy and periodontitis patients who were previously not diagnosed with diabetes mellitus. Materials and Methods: A total of 40 patients were selected for study and divided into two groups. Group 1 included patients with a healthy periodontium, and Group 2 included patients suffering from chronic periodontitis. Finger stick blood was collected by special collection unit (A1CNOW +® Bayer Health Care, Tarrytown New York, USA, for estimating level of HbA1c. Result: Both groups showed similar HbA1c levels clinically with slight increase in levels in the test group, but was statistically significant (test - 5.66 ± 0.35%, control - 5.17 ± 0.3% P = 0.003. Conclusion: Indians are at a high-risk of developing periodontitis and diabetes. These data suggest a possible link between periodontitis and glycemic control in nondiabetic individuals, periodontal disease may be a potential contributor to the development of type 2 diabetes.

    The application of principles and methods of cybernetics permits clinicians and managers to use feedback about care effectiveness and resource expenditure to improve quality and to control costs. Keys to the process are the specification of therapeutic goals and the creation of an organizational culture that supports the use of feedback to improve care. Daily feedback on the achievement of each patient's therapeutic goals provides tactical decision support, enabling clinicians to adjust care as needed. Monthly or quarterly feedback on aggregated goal achievement for all patients on a clinical pathway provides strategic decision support, enabling clinicians and managers to identify problems with supposed "best practices" and to test hypotheses about solutions. Work is underway at Vanderbilt University Medical Center to implement feedback loops in care and management processes and to evaluate the effects.

    Periodontitis is a complex, multifactorial disease and its susceptibility is genetically determined. The present book systematically reviews the evidence of the association between the genetic variants and periodontitis progression and/or treatment outcomes. Genetic syndromes known to be associated with periodontal disease, the candidate gene polymorphisms investigated in relation to periodontitis, the heritability of chronic and aggressive periodontitis, as well as common guidelines for association studies are described. This growing understanding of the role of genetic variation in inflammation and periodontal chronic disease presents opportunities to identify healthy persons who are at increased risk of disease and to potentially modify the trajectory of disease to prolong healthy aging. The book represents a new concept in periodontology with its pronounced focus on understanding through knowledge rather than presenting the presently valid answers. Connections between genetics and periodontology are systematically reviewed and covered in detail. (orig.)

    Periodontal tissues mount an immune inflammatory response to bacteria and their products. Certain inflammatory cytokines produced during periodontal inflammation increase the production of acute phase proteins like high‑sensitivity C‑reactive protein (hs‑CRP) and can depress erythropoietin production leading to the development of anemia. The aim of this study is to investigate the efficacy of nonsurgical periodontal therapy on red blood cell (RBC) parameters and hs-CRP in chronic periodontitis patients with anemia. This is a longitudinal, interventional study with 6-month follow-up. A total of 30 subjects with anemia and chronic periodontitis with age group of 33-55 years were selected by screening hemoglobin (Hb) levels and examining periodontal findings. The clinical parameters plaque index (PI), gingival index (GI), probing pocket depth (PPD) and clinical attachment level (CAL) were recorded at baseline. Laboratory blood investigations were performed to evaluate RBC count, Hb, packed cell volume (PCV), erythrocyte sedimentation rate (ESR) and red cell indices, hs-CRP at baseline. Nonsurgical periodontal therapy was performed for all patients. Patients were recalled after 6 months. The clinical and hematological parameters were re-evaluated to analyze the changes after nonsurgical periodontal therapy. The results showed that there was a significant increase in Hb levels, RBC count and PCV from baseline to 6 months after nonsurgical periodontal therapy. There is significant decrease in levels of ESR and hs-CRP levels after nonsurgical periodontal therapy indicating resolution of periodontal inflammation. There is a significant decrease in PPD, scores of PI and GI and significant increase in CAL gain. Minimal changes in mean corpuscular volume, mean corpuscular hemoglobin (MCH) and MCH concentration indicated that the lower values of red cell parameters are not due to any vitamin and mineral deficiencies, but secondary to the chronic inflammatory changes

    DNA microarray analysis is a computer based technology, that a reverse capture, which targets 10 periodontal bacteria (ParoCheck) is available for rapid semi-quantitative determination. The aim of this three-year retrospective study was to display the microarray analysis results for the subgingival biofilm samples taken from patient cases diagnosed with different forms of periodontitis. A total of 84 patients with generalized aggressive periodontitis (GAP,n:29), generalized chronic periodontitis (GCP, n:25), peri-implantitis (PI,n:14), localized aggressive periodontitis (LAP,n:8) and refractory chronic periodontitis (RP,n:8) were consecutively selected from the archives of the Oral Microbiological Diagnostic Laboratory. The subgingival biofilm samples were analyzed by the microarray-based identification of 10 selected species. All the tested species were detected in the samples. The red complex bacteria were the most prevalent with very high levels in all groups. Fusobacterium nucleatum was detected in all samples at high levels. The green and blue complex bacteria were less prevalent compared with red and orange complex, except Aggregatibacter actinomycetemcomitas was detected in all LAP group. Positive correlations were found within all the red complex bacteria and between red and orange complex bacteria especially in GCP and GAP groups. Parocheck enables to monitoring of periodontal pathogens in all forms of periodontal disease and can be alternative to other guiding and reliable microbiologic tests. Copyright © 2015 Elsevier Ltd.

    Objective: To investigate the periodontal status and associated risk factors among women of childbearing age to increase the awareness of oral health. Methods: The study was conducted on childbearing age women in Cixi, a city in Zhejiang Province in the southeast of China. A total of 754 women participated in periodontal examination while receiving prenatal care. Data of the women were collected from the Cixi Family Planning Commission and during an interview. Clinical periodontal indices, such as bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL) were measured during the examination. Statistical analysis on subject-based data was performed. Results: The prevalence of periodontal disease among childbearing age women in Cixi was high (84.7%). A significant association was found between the disease and educational level, pregnancy, taking oral contraceptives, stress, alcohol consumption, overweight, dental visit, and teeth brushing (Pperiodontal disease showed deep PD, obvious BOP, and clinical attachment loss. Among this population, pregnancy was closely associated with higher BOP percentage; teeth brushing no more than once per day or brushing for less than 1 min (Pperiodontal status of childbearing age women in Cixi needs to be improved urgently. Attention towards the periodontal health should be warranted, especially for those in special statuses and with poor awareness. PMID:23463766

    A cross-sectional study was conducted to investigate whether depression is associated with periodontal diseases in a representative sample of South Korean adults Methods: We used data from the sixth Korea National Health and Nutrition Examination Survey (KNHANES VI), conducted in 2014. We included in this study 4328 participants aged over 20 years (1768 males and 2560 females). Depression was assessed with the Patient Health Questionnaire (PHQ-9) and history of physician-diagnosed depression. Periodontal diseases were assessed a gingival bleeding, calculus and periodontal pockets. The data were analyzed using the chi-square test and multiple logistic regression. People with any periodontal diseases tended to be old, male, married, low income, poor education, blue-collar occupation, diabetes mellitus, hypertension, overweight, smoking, not using dental floss or interdental brush in univariate analysis. Neither self-reported nor diagnosed depression was associated with the presence of any or severe periodontal disease in the total sample. In participants aged 20-29 years only, the presence of any periodontal disease was associated with self-reported depression (OR, 2.031; 95% CI, 1.011-4.078). In the same age group, the presence of severe periodontal disease was associated with both self-reported depression (OR, 6.532; 95% CI, 2.190-19.483) and diagnosed depression (OR, 7.729; 95% CI, 1.966-30.389). Self-reported depression was significantly associated with the presence of any or severe periodontal disease, and diagnosed depression was significantly associated with severe periodontal diseases only in participants aged 20-29 years.

    Full Text Available Staphylococcus spp are not usually isolated from the oral cavity, and when this occurs, they are considered to belong to the transitory microbiota. Individuals with periodontal disease represent possible reservoirs of these opportunistic bacteria in the oral cavity. The use of antibiotics for treatment of periodontal disease or other infections may predispose to the increase of the number of Staphylococcus spp. in the oral cavity. These microorganisms easily become resistant to antibiotics, and may result in superinfection. The purpose of this study was to evaluate the presence of Staphylococcus spp. in the oral cavity and in periodontal pockets of patients with chronic periodontitis, identify the isolates and verify the relationship between the presence of Staphylococcus spp. in the oral cavity and presence of periodontal pockets. The study included eighty-eight patients, 25-60 years of age, with chronic periodontitis, and at least two sites with probing depth > 5 mm. Individual data examination was assessed. Then, samples were colleted from the periodontal pocket with the aid of paper tips and from the oral cavity through mouth rinses. Out of the total of patients, 37.50% presented Staphylococcus spp. in the periodontal pocket and 61.36% in the oral cavity, 27.27% presented the bacteria in both sites. S. epidermidis was the most prevalent specie in the periodontal pocket (15.9% and oral cavity (27.27%. The occurrence of higher proportions of nonresident's microorganisms in subgingival samples and oral sites may represent significant problem in causing and maintaining periodontal infections.Staphylococcus spp. não são usualmente isolados a partir da cavidade bucal.

    Full Text Available OBJECTIVE: The main objective of this study was to investigate the risk factors associated with periodontitis in pregnant women. METHODS: This study was conducted in two stages. In Stage 1, a cross-sectional study was conducted to determine the prevalence of periodontitis among 810 women treated at the maternity ward of a university hospital. In Stage 2, the factors associated with periodontitis were investigated in two groups of pregnant women: 90 with periodontitis and 720 without. A hierarchized approach to the evaluation of the risk factors was used in the analysis, and the independent variables related to periodontitis were grouped into two levels: 1 socio-demographic variables; 2a variables related to nutritional status, smoking, and number of pregnancies; and 2b variables related to oral hygiene. Periodontitis was defined as a probing depth > 4 mm and an attachment loss > 3 mm at the same site in four or more teeth. A logistic regression analysis was also performed. RESULTS: The prevalence of periodontitis in this sample was 11%. The variables that remained in the final multivariate model with the hierarchized approach were schooling, family income, smoking, body mass index, and bacterial plaque. CONCLUSION: The factors identified underscore the social nature of the disease, as periodontitis was associated with socioeconomic, demographic status, and poor oral hygiene.

    Full Text Available Dental plaque is the primary etiological factor in periodontal diseases. However, there are many factors that can modify how an individual periodontal tissue will respond to the accumulation of dental plaque. Among such risk factors, there is increasing evidence that smoking tobacco products alters the expression and rate of progression of periodontal diseases. The aim of this study was to find out the loss of periodontal tissue adhesion in smokers by measuring pocket depth using probe, and by measuring alveolar bone damage using Bone Loss Score (BLS radiographic methods on teeth 12, 11, 21, 22, 32, 31, 41, 42. Based on T Test statistical analysis, there were significant differences in pocket depth damage of alveolar bone in smokers and non smokers. In conclusion there were increasing pocket depth and alveolar bone damage in smokers.

    Full Text Available Introduction: Although bacterial plaque is regarded as the major cause of periodontitis, the role of smoking as an important risk factor has been established in the progression of periodontal disease. Thus, the present study aimed to evaluate knowledge and attitude of patients with periodontitis concerning effects of smoking on periodontal health. Method: In this descriptive cross-sectional study, 300 patients with periodontitis, aged between 18-74 years, were selected via convenience sampling out of patients referred to Periodontology Department of Shahid Sadoughi Dental Faculty and Khatam Alanbia professional clinic of Yazd. The study data were collected using a questionnaire, which were then analyzed by SPSS software (ver. 17 applying Chi-square, T-test and ANOVA statistical tests. Results: The mean total scores of patients' knowledge and attitude in regard with smoking effect on periodontal health were reported 86.7±18.4 and 48.1±7.3, respectively. A significant relationship was observed between knowledge and attitude with students' educational level. In the present study, 42% of smokers tried to quit smoking at least once, among which 14.3% of cases occured due to oral and dental health as well as consultation with dentists. Conclusion: The study findings showed despite patients' good knowledge concerning the effect of smoking on periodontal health, their attitude was reported moderate. Patients' moderate attitude can be mentioned as the main reason of continuing smoking despite their good knowledge. Moreover, dentists were demonstrated to have a negligible role with respect to patients' awareness in this regard.

    Increasing attention is being focused on evaluating the salivary microbiota as a promising method for monitoring oral health; however, its bacterial composition greatly differs from that of dental plaque microbiota, which is a dominant etiologic factor of oral diseases. This study evaluated the relative abundance of subgingival plaque-specific bacteria in the salivary microbiota and examined a relationship between the abundance and severity of periodontal condition in patients with periodontitis. Four samples (subgingival and supragingival plaques, saliva, and tongue coating) per each subject were collected from 14 patients with a broad range of severity of periodontitis before periodontal therapy. The bacterial composition was analyzed by 16S rRNA gene amplicon sequencing using Ion PGM. Of the 66 species-level operational taxonomic units (OTUs) representing the mean relative abundance of ≥ 1% in any of the four niches, 12 OTUs corresponding to known periodontal pathogens, including Porphyromonas gingivalis, were characteristically predominant in the subgingival plaque and constituted 37.3 ± 22.9% of the microbiota. The total relative abundance of these OTUs occupied only 1.6 ± 1.2% of the salivary microbiota, but significantly correlated with the percentage of diseased sites (periodontal pocket depth ≥ 4 mm; r = 0.78, P periodontal therapy, the total relative abundance of these 12 OTUs was evaluated as well as before periodontal therapy and reductions of the abundance through periodontal therapy were strongly correlated in saliva and subgingival plaque (r = 0.81, P bacteria representing the present condition of periodontal health.

    Full Text Available Periodontal health is influenced by a number of factors such as oral hygiene, genetic and epigenetic factors, systemic health, and nutrition. Many studies have observed that a balanced diet has an essential role in maintaining periodontal health. Additionally, the influences of nutritional supplements and dietary components have been known to affect healing after periodontal surgery. Studies have attempted to find a correlation between tooth loss, periodontal health, and nutrition. Moreover, bone formation and periodontal regeneration are also affected by numerous vitamins, minerals, and trace elements. The aim of this review is to critically appraise the currently available data on diet and maintenance of periodontal health and periodontal healing. The effects of nutritional intervention studies to improve the quality of life and well-being of patients with periodontal disease have been discussed.

    Full Text Available Background and aims. Visfatin, mainly secreted by visceral adipose tissue, especially by macrophages, plays an impor-tant role in regulating the defense and immune functions, and functions as a growth factor, a cytokine, an enzyme and more importantly as a proinflammatory mediator. The aim of the present study was to evaluate the effect of non-surgical perio-dontal treatment on serum and salivary levels of visfatin in patients with generalized moderate-to-severe chronic periodonti-tis. Materials and methods. Eighteen patients with generalized moderate-to-severe chronic periodontitis were selected based on periodontal parameters of gingival index (GI, probing pocket depth (PPD, clinical attachment level (CAL and radio-graphic parameters. Serum and salivary samples were collected at baseline and one month following non-surgical periodon-tal therapy (scaling and root planing ([SRP]. Visfatin levels were measured using an ELISA kit. Data were analyzed by SPSS 15, using paired t-test and Pearson’s correlation coefficient. Results. Mean salivary and serum levels of visfatin significantly decreased after non-surgical periodontal treatment (P<0.05. Changes in salivary visfatin levels were more prominent. Conclusion. According to the findings of this study it seems that there is a direct relationship between periodontal tissue inflammation and disease activity with salivary and serum visfatin levels.

    The National Health Insurance Service-National Sample Cohort and medical checkup data from 2002 to 2013 were used to evaluate the association between periodontal surgery for the treatment of periodontitis (PSTP) and vasculogenic erectile dysfunction (VED). Bivariate and multivariate logistic regression analyses were applied to a longitudinal retrospective database to assess the association between PSTP and VED while adjusting for the potential confounding effects of sociodemographic factors (age, household income, insurance status, health status, residence area, and smoking status) and comorbidities (diabetes mellitus, angina pectoris, cerebral infarction, and myocardial infarction). Among the 7,148 PSTP within the 268,296 recruited subjects, the overall prevalence of VED in PSTP was 1.43% (n=102). The bivariate analysis showed that VED was significantly related to PSTP (odds ratio [OR], 1.99; 95% confidence interval [CI], 1.38-2.06; P periodontal flap surgery had a significantly higher risk of VED, after adjusting for potential confounding factors. Further studies are required to identify the key mechanisms underlying the association between severe periodontal disease and VED.

    Sera from patients with periodontal infections contain elevated levels of C-reactive protein (CRP) compared to periodontally healthy individuals. Most studies to date have included patients with chronic periodontitis, and few investigators have studied CRP levels in subjects with aggressive periodontitis (AgP). The purpose of this study was to determine the relative levels of serum CRP in AgP patients and periodontally healthy subjects and to examine patients' characteristics that might account for intergroup differences. Serum samples were collected from 93 patients with generalized AgP (GAgP), from 97 patients with localized AgP (LAgP), and from 91 healthy controls (non-periodontitis [NP]). Periodontal examination consisted of plaque index, gingival index, probing depth, bleeding index, and attachment loss measurements. Current smoking was assessed by determination of serum cotinine levels by enzyme-linked immunosorbent assay (ELISA), and serum CRP levels were determined using a high-sensitivity ELISA assay. The three groups were significantly different from one another (P periodontal and demographic variables and current smoking, both mean probing depth and periodontal diagnosis remained correlated with CRP levels. Patients with AgP have statistically significant elevations in serum CRP levels compared to subjects without periodontitis. Elevated CRP in these subjects might represent a contribution of periodontal infections to systemic inflammation in relatively young individuals.

    Evidence has suggested that periodontal disease is associated with an increased risk of various adverse pregnancy and birth outcomes. However, several large clinical randomized controlled trials failed to demonstrate periodontal therapy during pregnancy reduced the incidence of adverse pregnancy and birth outcomes. It has been suggested that the pre-conception period may be an optimal period for periodontal disease treatment rather than during pregnancy. To date, no randomized controlled trial (RCT) has examined if treating periodontal disease before pregnancy reduces adverse birth outcomes. This study aims to examine if the pre-conception treatment of periodontal disease will lead to improved periodontal status during late pregnancy and subsequent birth outcomes. A sample of 470 (235 in each arm of the study) pre-conception women who plan to conceive within one year and with periodontal disease will be recruited for the study. All participants will be randomly allocated to the intervention or control group. The intervention group will receive free therapy including dental scaling and root planning (the standard therapy), supragingival prophylaxis, and oral hygiene education. The control group will only receive supragingival prophylaxis and oral hygiene education. Women will be followed throughout their pregnancy and then to childbirth. The main outcomes include periodontal disease status in late pregnancy and birth outcomes measured such as mean birth weight (grams), and mean gestational age (weeks). Periodontal disease will be diagnosed through a dental examination by measuring probing depth, clinical attachment loss and percentage of bleeding on probing (BOP) between gestational age of 32 and 36 weeks. Local and systemic inflammatory mediators are also included as main outcomes. This will be the first RCT to test whether treating periodontal disease among pre-conception women reduces periodontal disease during pregnancy and prevents adverse birth outcomes. If

    An infection-immune association of periodontal disease with rheumatoid arthritis has been suggested. This study aimed to investigate the effect of pre-existing periodontitis on the development and the immune/inflammatory response of pristane-induced arthritis. We investigated the effect of periodontitis induced by ligature placement and Porphyromonas gingivalis (P. gingivalis) infection, in combination with Fusobacterium nucleatum to promote its colonization, on the development of pristane-induced arthritis (PIA) in rats (Dark Agouti). Disease progression and severity of periodontitis and arthritis was monitored using clinical assessment, micro-computed tomography (micro-CT)/intraoral radiographs, antibody response, the inflammatory markers such as α-1-acid glycoprotein (α-1-AGP) and c-reactive protein (CRP) as well as cytokine multiplex profiling at different time intervals after induction. Experimentally induced periodontitis manifested clinically (P periodontitis-induction led to severe arthritis in all rats demonstrating that the severity of arthritis was not affected by the pre-existence of periodontitis. Endpoint analysis showed that 89% of the periodontitis-affected animals were positive for antibodies against arginine gingipain B and furthermore, the plasma antibody levels to a citrullinated P. gingivalis peptidylarginine deiminase (PPAD) peptide (denoted CPP3) were significantly (P periodontitis rats with PIA. Additionally, there was a trend towards increased pro-inflammatory and anti-inflammatory cytokine levels, and increased α-1-AGP levels in plasma from periodontitis-challenged PIA rats. Pre-existence of periodontitis induced antibodies against citrullinated peptide derived from PPAD in rats with PIA. However, there were no differences in the development or severity of PIA between periodontitis challenged and periodontitis free rats.

Differentiating between a periodontal and an endodontic problem can be difficult. A symptomatic tooth may have pain of periodontal and/or pulpal origin. The nature of that pain is often the first clue in determining the etiology of such a problem. Radiographic and clinical evaluation can help clarify the nature of the problem. In some cases, the influence of pulpal pathology may cause the periodontal involvement and vice versa.

    Periodontal disease is an inflammatory disease of the tissues supporting the teeth. Women who have periodontal disease while pregnant may be at risk of adverse pregnancy outcomes. Although the association between periodontal disease and adverse pregnancy outcomes has been addressed in a considerable number of systematic reviews and meta-analyses, there are important differences in the conclusions of these reviews. Systematic reviews assessing the effectivity of various therapeutic interventions to treat periodontal disease during pregnancy to try and reduce adverse pregnancy outcomes have also arrived at different conclusions. We aim to provide a systematic overview of systematic reviews comparing the frequency of adverse pregnancy outcomes between women with and without periodontal disease and/or evaluating the effect of preventive and therapeutic interventions for periodontal disease before or during pregnancy on adverse pregnancy outcomes. We will include systematic reviews reporting on studies comparing adverse pregnancy outcomes: (i) between women with or without periodontal disease before (pregnancy and/or (ii) according to preventive or therapeutic interventions for periodontal disease. Eligible interventions include (combinations of) the following: oral hygiene education, use of antibiotics, subgingival scaling, and root planing. For preventive and/or therapeutic reviews, the following comparisons will be considered: no intervention, a placebo intervention, or an alternative intervention. Our primary adverse pregnancy outcomes of interests are maternal mortality, preterm delivery, and perinatal mortality. Two reviewers will independently identify eligible published and unpublished systematic reviews from six electronic databases and using hand searching of reference lists and citations. Data items extracted from included systematic reviews are based on the Cochrane Effective Practice and Organization of Care checklist and the preferred reporting items for

    During the last three to four decades, extensive changes in opinion concerning the etiology, pathogenesis, and treatment of periodontal disease have taken place. During these decades, contributing factors are standardized and controlled trials, as well as epidemiological studies, were performed. Periodontics is no longer an art as it was at the end of the 19th century- it is a science based on research. Pyorrhea alveoiaris or periodontitis has been considered a multifactorial disease with bad prognosis which, together with caries, causes loss of teeth in the population. It was supposed to affect most of the population with age progress, trauma from occlusion, systemic diseases, and bad oral hygiene. The discovery that plaque was the cause of gingivitis, and that the subgingival microflora differed in composition between sites, teeth, and individuals created new suggestions and demands for the treatment of periodontal disease. The aim of this paper is to summarize some modern aspects on periodontal disease. (author)

The aim of this study is to investigate the bibliometrics of periodontal literature, assessing the geographic origin, study design, and topics investigated in periodontal research published from 1995 to 2010. Articles published in periodontal journals during 1995 to 2010 were retrieved through hand search. Inclusion/exclusion criteria were applied. The following variables were extrapolated from each article: number of authors, study design, topic investigated, financial support, and geographic origin. The general linear model assessed the influence of independent variables on number of authors per article, and χ(2) test assessed the statistical difference of the variables over years 1995 to 2010. A total of 2,260 articles were reviewed; 2,076 met the inclusion criteria. The number of authors per article increased (P <0.001) from 4.0 (1995) to 5.1 (2010). The proportion of articles published from North America and Europe decreased (P <0.001) from 84.3% (1995) to 58.6% (2010), whereas for Asia and South America the article proportion increased (P <0.001) from 13.8% (1995) to 40% (2010). Research targeting prevention and treatment of periodontal disease is decreasing (P <0.001) in favor of implant-related research. Governmental research funding is increasing (P <0.001). Periodontal research significantly changed during the last 15 years.

    Little is known about the financial costs that smoking adds to the life-time treatment of periodontal disease. The total life-time cost of periodontal treatment was modelled using data from private periodontal practice. The costs of initial and supportive therapy, re-treatment and tooth replacements (with bridgework or implants) were identified using average dental charges from the American Dental Association survey. Smoking costs at $6 and $10 for 20 cigarettes were compared to the costs of life-time periodontal treatment for stable and unstable compliant patients. Smoking added 8.8% to the financial cost of the life-time cost of periodontal therapy in stable maintenance patients, 40.1% in patients who needed one extra maintenance visit and 71.4% in patients who needed two extra maintenance visits per year in addition to added re-treatment. The cost of smoking far exceeded the cost of periodontal treatment; For patients who smoked 10 to 40 cigarettes per day at the cost of $6 or $10 a pack, the cost of smoking exceeded the cost of life-time periodontal treatment by between 2.7 and 17.9 times. Smoking 40 cigarettes at $10 a packet for 3.4 years would pay for the entire life-time cost of periodontal treatment. Smoking adds considerable extra financial costs to the life-time treatment of periodontal diseases. The cost of smoking itself exceeds the cost of periodontal therapy.

    Inflammation of tooth supporting structures is referred to as periodontitis. C-reactive proteins (CRP) levels are usually increased in case of chronic inflammatory process like periodontitis. Association of CRP with pregnancy has been observed in the past, which includes most commonly preterm delivery, preeclampsia, etc. Therefore, it can be hypothesized that CRP may act as a link between periodontitis and adverse pregnancy outcomes. Hence, we aim to evaluate the plasma CRP levels in pregnant women with and without periodontal pathologies. The study included 210 pregnant women who reported to the hospital with periodontal problems and for routine checkups. All the patients were divided into three groups based on the presence and absence of periodontal pathologies. Russell's Periodontal Index Score was used for the evaluation of periodontal status of the subjects. While comparing the mean CRP levels in all the three study groups, statistically significant results were obtained. Statistically significant results were obtained while comparing the mean CRP levels in group C patients before treatment and after treatment therapy. The CRP levels were estimated by taking blood samples. Paired t-test and one-way analysis of variance was used to assess the correlation between the two parameters. Casual association might exist between the CRP levels and periodontal diseases in pregnant women and the CRP levels may also get elevated in pregnant women.

    This study compared the composition of subgingival microbiota between obese and non-obese women with or without periodontal disease. Full-mouth periodontal clinical assessments were carried out in 76 obese women (17 periodontally healthy and 59 with periodontal disease), and 34 non-obese women (12 periodontally healthy, 22 with periodontal disease). Subgingival biofilm samples were individually obtained from seven sites of each individual, and the prevalence and counts of 40 bacterial taxa were determined by the checkerboard method. The frequency and counts of each species were computed for each individual and across the groups. Differences among and between groups were sought by the Kruskal-Wallis and Mann-Whitney tests, respectively. Possible correlations between obesity and clinical and microbiologic parameters were tested with Spearman correlation coefficient. Streptococcus sanguinis, Streptococcus oralis, and Capnocytophaga ochracea were found in significantly higher levels in obese compared with non-obese women (P periodontal health, Porphyromonas gingivalis and Leptotrichia buccalis were detected in higher mean frequency and/or counts in obese women than in non-obese women, whereas in patients with periodontal disease, obese women harbored greater levels of C. ochracea than non-obese women (P periodontal disease presented significantly greater mean counts of P. gingivalis and Tannerella forsythia than non-obese women with periodontal health (P periodontal disease are present at the same time, significant positive correlations were detected with C. ocharcea, P. gingivalis, S. sanguinis, and T. forsythia. Few differences in the composition of the subgingival microbiota of obese and non-obese women with periodontal health or disease were found. However, a high prevalence of P. gingivalis in obese women with periodontal health was observed. © 2018 American Academy of Periodontology.

    Wang, Chin-Wei Jeff; McCauley, Laurie K

    2016-12-01

    Osteoporosis and periodontitis are both diseases characterized by bone resorption. Osteoporosis features systemic degenerative bone loss that leads to loss of skeletal cancellous microstructure and subsequent fracture, whereas periodontitis involves local inflammatory bone loss, following an infectious breach of the alveolar cortical bone, and it may result in tooth loss. Most cross-sectional studies have confirmed the association of osteoporosis and periodontitis primarily on radiographic measurements and to a lesser degree on clinical parameters. Multiple shared risk factors include age, genetics, hormonal change, smoking, as well as calcium and vitamin D deficiency. Both diseases could also be risk factors for each other and have a mutual impact that requires concomitant management. Suggested mechanisms underlying the linkage are disruption of the homeostasis concerning bone remodeling, hormonal balance, and inflammation resolution. A mutual interventional approach is emerging with complex treatment interactions. Prevention and management of both diseases require interdisciplinary approaches and warrants future well-controlled longitudinal and interventional studies for evidence-based clinical guidelines.

    Periodontitis is a chronic oral inflammatory disease caused by microorganisms. Human β-defensin-3 (HBD-3) is an endogenous antimicrobial peptide that inhibits a broad spectrum of microorganisms. Cell sheet technology has been widely applied in tissue and organ reconstructions. In the current study, it was aimed to investigate the anti-inflammatory effect of periodontal tissue engineered by HBD-3 gene-modified periodontal ligament cell (PDLC) sheets, and to identify a suitable method of promoting the regeneration of periodontal tissues. Western blot analysis and antimicrobial tests were used to confirm the expression of HBD-3. The effect of the cell sheets on anti-inflammatory activity and bone remodeling in a dog model of periodontitis was demonstrated by immunohistochemistry. The results demonstrated that the transfected PDLCs stably expressed HBD-3. Periodontal pathogens were susceptible to the antimicrobial activity of the cell sheets. In addition, the cell sheets relieved the bone resorption caused by inflammation in the in vivo model. HBD-3 may potentially be applied in the treatment of periodontitis and may function as osteogenic promoter via its anti-inflammatory effect. PMID:28944821

    Periodontal diseases are the most common bacterial infection predominantly associated with Gram-negative microorganisms that exist in the subgingival biofilm. Analysis of saliva provides a noninvasive means of evaluating the role of the host response in periodontal disease. Though salivary enzymes can be used as the biomarkers, neopterin has been recently used as one of the important diagnostic tools in the field of periodontics. Hence, we aimed to identify the neopterin levels in unsimulated saliva from the chronic periodontitis patients and compare them with the periodontally healthy subjects. Twenty subjects participated in the study and were categorized as the experimental group (chronic periodontitis patients) and control groups (healthy subjects). Unstimulated saliva samples were collected from both the groups for neopterin estimation. Neopterin in saliva was estimated using Shimadzu High Performance Liquid Chromatography with LC-20AD pump system, equipped with RF-10 AXL fluorescence detector. Data were expressed as mean±SD and analyzed using GraphPad Prism version 6.0 (California, USA). Statistical analysis was done by Student's t-test. The neopterin level in unstimulated saliva was found to be higher in the experimental group than the control group with P≤0.05. The chronic periodontitis patients showed higher neopterin level in unstimulated saliva as compared to control. Hence, neopterin can be used as a potential biomarker for identification of the periodontal disease in its initial stage can help in preventing the disease progression.

    The anatomical and structural characteristics of the pulp make this structure prone to altering as a result of, for instance, periodontal conditions (proximity), iatrogenic alterations, infections and involvement of vascular and nerve structures (it is surrounded by hard tissues that prevent expansion), to name just a few. Pulpitis is a process that courses with pain of varying intensity that allows us to determine the location of the lesion in clinical terms. Its evolution varies and may even progress to pulpar necrosis that in turn, produces neuritis-like pain. Diagnosis is established by means of clinical symptomatology and supported by X-rays, palpation of tissues at painful sites, application of electrical stimuli, heat, etc. Periodontitis is a bacterial infection originating in the apex. The most important form is the so-called acute apical periodontitis that arises as a result of a prior episode of pulpitis. It is characterized by acute pain located in the tooth, accompanied by the feeling of having a long-tooth. The patient refers being unable to chew on that side; there may be painful mobility of the tooth and an outflow of pus that alleviates symptoms. X-rays do not provide a lot of information, but may attest to a widening of the apical space. This pathology may disseminate to surrounding tissues, leading to conditions of considerable severity.

    LP533401 is an inhibitor of tryptophan hydroxylase 1, which regulates serotonin production in the gut. Previous work indicates that LP533401 has an anabolic effect in bone. Thus, we hypothesized that inhibition of gut serotonin production may modulate the host response in periodontal disease. In this study, we aimed to analyze the effects of LP533401 in a rat periodontitis model to evaluate the role of gut serotonin in periodontitis pathophysiology. Twenty-four rats were divided into three groups: treated group (T: ligature-induced periodontal disease and LP533401, 25 mg/kg/d) by gavage; ligature group (L: ligature-induced periodontal disease only); and control group (C: without ligature-induced periodontal disease). After 28 d, radiographic alveolar bone support was measured on digital radiographs, and alveolar bone volume fraction, tissue mineral density and trabeculae characteristics were quantified by microcomputed tomography in the right hemi-mandible. Left hemi-mandibles were decalcified and alveolar bone loss, attachment loss and area of collagen in the gingiva were histologically analyzed. Significant difference between the L and C groups was found, confirming that periodontal disease was induced. We observed no difference between the T and L groups regarding alveolar bone destruction and area of collagen. LP533401 (25 mg/kg/d) for 28 d does not prevent bone loss and does not modulate host response in a rat model of induced periodontal disease. © 2016 John Wiley & Sons A/S.

    Inflammatory periodontal diseases are highly prevalent, although most of these diseases develop and progress slowly, often unnoticed by the affected individual. However, a subgroup of these diseases include aggressive and acute forms that have a relatively low prevalence but show a rapid-course, high rate of progression leading to severe destruction of the periodontal tissues, or cause systemic symptoms that often require urgent attention from healthcare providers. Aggressive periodontitis is an early-onset, destructive disease that shows a high rate of periodontal progression and distinctive clinical features. A contemporary case definition of this disease is presented. Population studies show that the disease is more prevalent in certain geographic regions and ethnic groups. Aggressive periodontitis is an infectious disease, and recent data show that in affected subjects the subgingival microbiota is composed of a mixed microbial infection, with a wide heterogeneity in the types and proportions of microorganisms recovered. Furthermore, there are significant differences in the microbiota of the disease among different geographic regions and ethnicities. There is also evidence that the Aggregatibacter actinomycetemycomitans-JP2 clone may play an important role in the development of the disease in certain populations. The host response plays an important role in the susceptibility to aggressive periodontitis, where the immune response may be complex and involve multiple mechanisms. Also, genetic factors seem to play an important role in the pathogenesis of this disease, but the mechanisms of increased susceptibility are complex and not yet fully understood. The available data suggest that aggressive periodontitis is caused by mutations either in a few major genes or in multiple small-effect genes, and there is also evidence of gene-gene and gene-environment interaction effects. Diagnostic methods for this disease, based on a specific microbiologic, immunologic or

    Periodontal disease is a chronic inflammatory disease of the jaws and is more prevalent in obesity. Local and systemic oxidative stress may be an early link between periodontal disease and obesity. The primary aim of this study was to detect whether increased periodontal disease susceptibility in obese individuals is associated with local and systemic oxidative stress. Accordingly; we analyzed periodontal status and systemic (serum) and local (gingival crevicular fluid [GCF]) oxidative status markers in young obese women in comparison with age-matched lean women.Twenty obese and 20 lean women participated. Periodontal condition was determined by clinical periodontal indices including probing depth, clinical attachment level, gingival index, gingival bleeding index, and plaque index. Anthropometric, hormonal, and metabolic measurements were also performed. Blood and GCF sampling was performed at the same time after an overnight fasting. Serum and GCF total antioxidant capacity (TAOC), and total oxidant status (TOS) levels were determined, and oxidative stress index (OSI) was calculated.Clinical periodontal analyses showed higher gingival index and gingival bleeding index in the obese group (P = 0.001 for both) with no significant difference in probing depth, clinical attachment level, and plaque index between the obese and the lean women. Oxidant status analyses revealed lower GCF and serum TAOC, and higher GCF and serum OSI values in the obese women (P < 0.05 for all). GCF TOS was higher in the obese women (P < 0.05), whereas there was a nonsignificant trend for higher serum TOS in obese women (P = 0.074). GCF TAOC values showed a negative correlation with body mass index, whereas GCF OSI was positively correlated with fasting insulin and low-density lipoprotein-cholesterol levels (P < 0.05 for all). Clinical periodontal indices showed significant correlations with body mass index, insulin, and lipid levels, and also oxidant status markers

    Bone sialoprotein (BSP) is an acidic phosphoprotein with collagen-binding, cell attachment, and hydroxyapatite-nucleating properties. BSP expression in mineralized tissues is upregulated at onset of mineralization. Bsp-null (Bsp-/-) mice exhibit reductions in bone mineral density, bone turnover, osteoclast activation, and impaired bone healing. Furthermore, Bsp-/- mice have marked periodontal tissue breakdown, with a lack of acellular cementum leading to periodontal ligament detachment, extensive alveolar bone and tooth root resorption, and incisor malocclusion. We hypothesized that altered mechanical stress from mastication contributes to periodontal destruction observed in Bsp-/- mice. This hypothesis was tested by comparing Bsp-/- and wild-type mice fed with standard hard pellet diet or soft powder diet. Dentoalveolar tissues were analyzed using histology and micro–computed tomography. By 8 wk of age, Bsp-/- mice exhibited molar and incisor malocclusion regardless of diet. Bsp-/- mice with hard pellet diet exhibited high incidence (30%) of severe incisor malocclusion, 10% lower body weight, 3% reduced femur length, and 30% elevated serum alkaline phosphatase activity compared to wild type. Soft powder diet reduced severe incisor malocclusion incidence to 3% in Bsp-/- mice, supporting the hypothesis that occlusal loading contributed to the malocclusion phenotype. Furthermore, Bsp-/- mice in the soft powder diet group featured normal body weight, long bone length, and serum alkaline phosphatase activity, suggesting that tooth dysfunction and malnutrition contribute to growth and skeletal defects reported in Bsp-/- mice. Bsp-/- incisors also erupt at a slower rate, which likely leads to the observed thickened dentin and enhanced mineralization of dentin and enamel toward the apical end. We propose that the decrease in eruption rate is due to a lack of acellular cementum and associated defective periodontal attachment. These data demonstrate the importance of BSP

    Full Text Available Stress is hypothesized as a common pathway for several related chronic diseases of man. Psychosocial stress as modified by perceptions and coping by patients can lead to physical processes. Psychoneuroimmunologic (PNI studies have suggested that psychosocial stress can alter immune function and increase vulnerability to illnesses. The patients also have high sensitivity to periodontal disease (PD. This article describes the association of stress as a physiological response to diseases such as PD, rheumatoid arthritis (RA, and inflammatory bowel disease. The psychosocial stress can lead to physiological processes through 1 the hypothalamic-pituitary-adrenal (HPA axis leading to glucocortico-steroid secretion; 2 the autonomic nervous system, resulting in the release of catecholamine; or 3 the hypothalamic-pituitary-gonadal axis, resulting in the release of sex hormones. These processes may affect chronic diseases. It can be concluded that psychosocial stress in periodontal disease patients must be considered and social support must be provided in order to achieve an optimum periodontal therapy result.

    2014-01-01

    Treatment of periodontal disease is a complex and multidisciplinary procedure, requiring periodontal, surgical, restorative, and orthodontic treatment modalities. Several authors attempted to formulate models for periodontal treatment that orders the treatment steps in a logical and easy to remember manner. In this article, we discuss two models of periodontal treatment planning from two of the most well-known textbook in the specialty of periodontics internationally. Then modify them to arrive at a new model of periodontal treatment planning, The Trimeric Model. Adding restorative and orthodontic interrelationships with periodontal treatment allows us to expand this model into the Extended Trimeric Model of periodontal treatment planning. These models will provide a logical framework and a clear order of the treatment of periodontal disease for general practitioners and periodontists alike. PMID:25177662

    Full Text Available Periodontal disease is one of the risk factors for certain systemic conditions. Retrospective and prospective studies showed that pregnant women with periodontitis have significantly higher risk to deliver preterm low birth weight infants (gestation period < 37 weeks and birth weight < 2500 grams, and the risk increase as the periodontitis progressed during pregnancy. Periodontal disease could mediate this systemic effect through the action of periodontal pathogens and lipopolysaccharide increasing the production of prostaglandin and cytokine (physiologic mediators in parturition which will trigger the delivery of preterm low birth weight among women with periodontitis. It is concluded that periodontal disease is an independent risk factor for preterm low birth weight, and inclusion of oral prophylaxis procedure during pregnancy should be considered.

    periodontal diseases and OHRQoL while eight of the publications highlighted a dose-response relationship between and extent and severity of periodontal disease and the impact on OHRQoL.ConclusionsThe findings support the association between clinically diagnosed periodontal diseases and subjectively assessed OHRQoL with a dose-response relationship demonstrated. In summation, periodontal diseases play a significant role in oral health and impact on the QoL of affected individuals. In publications that undertook a full mouth recording the results were more evident, therefore a comprehensive periodontal exam in conjunction with a validated OHRQoL questionnaire is recommended.

    Cranberries, high in polyphenols, have been associated with a favorable glycemic response in patients with type 2 diabetes and also are beneficial for oral health. Because type 2 diabetes mellitus and periodontal disease have a physiological relationship, this study aimed to evaluate the hypothesis that cranberry juice enriched with omega-3 will improve glycemic and lipid profiles and periodontal status in patients with diabetes with periodontal disease. In this randomized clinical trial, 41 patients with diabetes (age 35-67 years) with periodontal disease were recruited and randomly assigned to 4 groups: control (C; n = 12), receiving omega-3 (I1; n = 10, 1 g/ twice daily), cranberry juice (I2; n = 9, 200 ml, twice daily), and cranberry juice enriched with omega-3 (I3; n = 10, 200 ml, containing 1 g omega-3) twice daily for 8 weeks. Nonsurgical periodontal therapy was provided for all patients during the study. Fasting blood glucose and glycated hemoglobin, lipid profile, probing depth, anthropometric indices, and 3-day 24-hour dietary recalls were measured pre- and postintervention. Glycated hemoglobin was decreased significantly in I1 and I3 groups. Serum high-density lipoprotein cholesterol (HDL-C) levels increased significantly in the I3 group compared to baseline and compared to I1 and I2 groups. Probing depth was significantly reduced in all groups postintervention. Consumption of cranberry juice enriched with omega-3 can be beneficial as adjuvant therapy with nonsurgical periodontal therapy in decreasing glycated hemoglobin, increasing HDL-C, and improving periodontal status in patients with diabetes with periodontal disease.
