    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

    Context: Current clinical periodontal diagnostic techniques emphasize the assessment of clinical and radiographic signs of periodontal diseases which can provide a measure of history of disease. Hence, new methodologies for early identification and determination of periodontal disease activity need to be explored which will eventually result in expedited treatment. Aim: To evaluate the correlation of alkaline phosphatase (ALP) activity in gingival crevicular fluid (GCF) to clinical parameters of periodontal inflammation in smokers with chronic periodontitis. Materials and Methods: Study population included 15 smoker male patients in the age group of 35–55 years suffering from moderate generalized chronic periodontitis with history of smoking present. Following parameters were evaluated at baseline, 1 month and 3 months after scaling and root planing: plaque index, bleeding index, probing pocket depth (PD), relative attachment level (RAL), and GCF ALP activity. Statistical Analysis Used: Independent variables for measurements over time were analyzed by using Wilcoxon signed rank test. Results: A statistically significant reduction in all the clinical parameters and GCF ALP activity was observed from baseline to 1 month and 3 months. A correlation was observed between change in GCF ALP activity and PD reduction as well as gain in RAL at 3 months. Conclusion: The present study emphasizes that total ALP activity could be used as a marker for periodontal disease activity in smokers. Estimation of changes in the levels of this enzyme has a potential to aid in the detection of progression of periodontal disease and monitoring the response to periodontal therapy. PMID:27563197

    Full Text Available BACKGROUND: The contribution of HIV-infection to periodontal disease (PD is poorly understood. We proposed that immunological markers would be associated with improved clinical measures of PD. METHODS: We performed a longitudinal cohort study of HIV-infected adults who had started highly active antiretroviral therapy (HAART 0mm, clinical attachment level (CAL ≥ 4.0mm, and bleeding on probing (BOP at ≥ 4 sites/tooth and microbiologically as specific periodontopathogen concentration. Linear mixed-effects models were used to assess the associations between immune function and PD. RESULTS: Forty (40 subjects with median 2.7 months on HAART and median nadir CD4+ T-cell count of 212 cells/μl completed a median 3 visits. Over 24 months, CD4+ T-cell count increased by a mean 173 cells/µl (p<0.001 and HIV RNA decreased by 0.5 log10 copies/ml (p<0.001; concurrently, PPD, CAL and BOP decreased by a mean 11.7%, 12.1%, and 14.7% respectively (all p<0.001. Lower nadir CD4+ T-cell count was associated with worse baseline REC (-6.72%; p=0.04 and CAL (9.06%; p<0.001. Further, lower nadir CD4+ T-cell count was associated with a greater relative longitudinal improvement in PPD in subjects with higher baseline levels of Porphyromonas gingivalis (p=0.027, and BOP in subjects with higher baseline levels of Porphyromonas gingivalis or Treponema denticola (p=0.001 and p=0.006 respectively. Longitudinal changes from baseline in CD4+ T-cell count and level of HIV RNA were not independently associated with longitudinal changes in any clinical markers of PD. CONCLUSION: Degree of immunosuppression was associated with baseline gingival recession. After HAART initiation, measures of active PD improved most in those with lower nadir CD4+ T-cell counts and higher baseline levels of specific periodontopathogens. Nadir CD4+ T-cell count differentially influences periodontal disease both before and after HAART in HIV-infected adults.

    Full Text Available Statement of Problem: There is a controversy about the relationship between pulpal and periodontal diseases. The interrelationship between pulp and periodontium could have an important effect on the treatment plan of the tooth. Purpose: The aim of the present research is to evaluate root canal therapy effects on periodontal healing of teeth with chronic advanced periodontitis. Materials and Methods: In this randomized controlled clinical trial 32 single rooted teeth which had necrotic pulp or irreversible pulpitis in 7 patients with chronic advanced periodontitis were selected based on specific criteria. Using a split mouth design, teeth were randomly put in two groups of test and control. In the test group root canal therapy ,scaling & root planing were done.In the control group, only scaling & root planing were performed. Clinical parameters including Pocket Depth (PD, Clinical Attachment Level (CAL, mobility, pattern of bone destruction and plaque index (PI were evaluated in two groups at base line, 1 and 3 months after treatment. Appropriate tests such as paired Wilcoxon and Mann-Whitney were performed. Results: Statistically significant reductions were found in the test group when comparing baseline and one-month post treatment values for Clinical Attachment level (CAL but not after 3-months. In the control group the CAL reductions were not statistically significant between baseline and one month post-treatment, but a increase were observed between one month and three months after treatment. There was a statstically significant difference between the test and the control groups. Other parameters didn’t show any significant differences in each group and between two groups. Conclusion: Since clinical attachment level was the most important parameter we found it can high lighted the role of pathogene with pulpal origin in progression of periodeontal disease and it is concluded that beside periodontal treatment in some advanced periodontal

    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.

    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.

    Full Text Available Background: Conventional, non-surgical periodontal therapy consists of supra- and subgingival tooth debridement. However, it is a technically demanding procedure and is not always efficient at eradicating all periodontal pathogens and in reducing inflammation. Therefore, local subgingival application of other chemotherapeutic agents may be used as an adjunct to non-surgical therapy. The aim of this study was to investigate the clinical and histological outcomes of local subgingival application of 0.2% hyaluronic acid gel (GENGIGEL® as an adjunct to scaling and root planing (SRP in chronic periodontitis patients. Materials and Methods: One hundred and twenty sites were chosen from 26 patients with chronic periodontitis (criteria being periodontal pockets ≥5mm. Experimental sites additionally received HA gel subgingivally at baseline, 1 st , 2 nd , and 3 rd week. Clinical parameters were re-assessed at 4 th , 6 th , and 12 th week. At 4 th week recall, a gingival biopsy was obtained from test and control site for histologic examination. Results: Intra-group analysis of all the clinical parameters at all sites from baseline to 4 th , 6 th , and 12 th week showed statistically significant changes. Experimental sites showed statistically significant improvement in Gingival index and Bleeding index at 6 th and 12 th week when compared with control sites. However, no statistically significant differences were observed in the PPD and RAL between control and experimental sites at 4 th , 6 th , and 12 th week time interval. No statistically significant association was found between the histological grading of the sites that received HA treatment. Conclusion: Subgingival placement of 0.2% HA gel along with SRP provided a significant improvement in gingival parameters. However, no additional benefit was found in periodontal parameters. Histologically, experimental sites showed reduced inflammatory infiltrate, but it was not statistically significant.

    The Z-Scan (ZS) technique in the thermal regime has been used to measure the nonlinear optical response of low-density lipoprotein (LDL). The ZS technique is carried out in LDL from 40 patients with chronic periodontitis before and after three, six, and 12 months of periodontal treatment. Clinical parameters such as probing depths, bleeding on probing, total and differential white blood cells counts, lipid profiles, cytokine levels, and antibodies against oxidized LDL are also determined and compared over time. Before the treatment, the ZS experimental results reveal that the LDL particles of these patients are heavily modified. Only after 12 months of the periodontal treatment, the ZS results obtained reveal behavioral characteristics of healthy particles. This conclusion is also supported by complementary laboratorial analysis showing that the periodontal treatment induces systemic changes in several inflammatory markers.

    Recent studies have indicated that the destruction in chronic periodontal disease occurs in relatively short periods of time which are followed of prolonged periods of inactivity. These bursts of activity are characterized by an increase in the inflammatory reaction. It has been the purpose of this paper to study the correlation between the clinical measurements of periodontal disease and the histomorphometric quantification of areas of dense inflammatory infiltrate. The results of this study show that the clinical parameters that measure gingival inflammation or loss of periodontal attachment are useful to distinguish pathology from normal (p less than 0.003), but lack sensitivity to detect burst of periodontal disease activity (p greater than 0.05).

    Calcium antagonists are widely used in treating acute and chronic coronary insufficiency disorders. A major side effect of long-term treatment is gingival hyperplasia. In the present study, 70 patients taking nifedipine for at least six months and 70 controls similar in age, gender, approximal hygiene and systemic disease with at least 6 anterior teeth in upper and lower arches were examined. Their periodontal conditions were determined by modified Sulcus-Bleeding-Index (mSBI), modified Approximal-Plaque-Index (mAPI), Community Periodontal Index of Treatment Needs (CPITN), a hyperplasia index quantifying the extent of gingival overgrowth, probing depths, clinical attachment loss and the modified Phenytoin-Gingival-Inflammation-Index (mPGI). A mild to moderate gingival hyperplasia was diagnosed in 21 of 70 patients resulting in a prevalence of 30% compared to 8.5% in controls. The hyperplastic changes were situated mainly in the anterior region of the dentition. Significant differences between both groups could be found comparing the severity of the gingival hyperplasia, the CPITN, mSBI, probing depths and the part of mPGI evaluating colour and turgor of the gingiva (p periodontal treatment need and the approximal hygiene of the patients. No statistically significant correlation could be found between the severity of gingival hyperplasia and the age and gender of the patient, or the dose or duration of nifedipine therapy. Gingival changes seemed to be more pronounced in patients with cardiovascular disorders than in patients under hemodialysis. The high incidence of gingival hyperplasia in patients receiving nifedipine on a long-term basis emphasises the role of the dentist and general practitioner in the early detection and prophylaxis of gingival changes and requires a thorough information to the patient concerning periodontal side effects.

    Full Text Available Scope of the study: A comparative analysis on the reliability of the methods of oral rehabilitation of partial edentation through fixed prostheses on dental support vs. prostheses on implants in patients with periodontal diseases. Materials and method: The experimental group was formed of 56 patients (25 men and 31 women, with ages between 23 and 68 years, and different classes of partial edentation in patients with a periodontopathed field. Mention should be made of the fact that, in the case of terminal edentations, a corresponding number of implants has been used, so that to reduce, as much as possible, the number of intermediates involved in the bridge bodies entering the structure of the prosthetic works with dental-implantary support. Results: The survival ratio for the implants substituting the periodontally-induced dental losses was of 90.5%, while that of the implants for the replacement of the teeth lost from other causes (caries, fractures, traumatisms was of 96.5%. Conclusions: The present study supports the assertion that, if the specific conditions of the clinical case under discussion permit it, fixed prosthesizing on a mixed implanto-dental support is more indicated, if considering that this type of prosthesis causes less negative modifications of the prosthetic field, comparatively with the partially-mobile one.

    Background: It is well-recognized fact that periodontal diseases are caused by multifactorial etiologies, in which microorganisms play an important role. An essential component of therapy is to eliminate or manage these pathogens. This has been traditionally accomplished through mechanical means by scaling and root planning which is ineffective in some of the aggressive periodontal diseases. These aggressive diseases involve particular groups of microorganisms which are not eliminated by mechanical means; and they require anti-infective therapy, which includes local and systemic antimicrobials. This approach of therapy is of interest to periodontist due to the aforementioned shortcomings of conventional methods. Materials and Methods: A manual and electronic search was made for human studies up to March 2011 that presented clinical and microbiological data for the efficacy of a systemic antibiotics in generalized aggressive periodontitis along with scaling and root planning. A systematic approach was followed by two independent reviewers and included eligibility criteria for study inclusion, quality assessment, and determination of outcome measures, data extraction, data synthesis, and drawing of conclusion. Results: Only three randomized controlled human trials qualified, and they concluded that both scaling and root planing (SRP) mono-therapy and SRP with antibiotics proves beneficial in improving clinical and microbiological parameters in aggressive periodontitis. Better results were seen in SRP with antibiotic groups as compared with SRP alone. Conclusion: Because of the insufficient quantity and heterogenecity of studies, no adequate evidence could be gathered to use the beneficial effects of these antibiotics along with SRP in aggressive periodontitis compared with SRP alone.

    Full Text Available Background: Assess the prevalence of herpesviruses in healthy subjects, gingivitis, and chronic periodontitis patients, to assess the relationship between the prevalence of herpesviruses and periodontal clinical parameters, and to evaluate the effect of phase-I therapy on the level of viral detection. Materials and Methods: Hundred patients consisting of 20 healthy subjects, 40 gingivitis, and 40 chronic periodontitis were included in the study. Clinical parameters recorded included plaque index, gingival index, sulcus bleeding index, probing depth, and clinical attachment level. The gingivitis and chronic periodontitis patients received phase-I periodontal therapy including oral hygiene instructions, full mouth scaling for gingivitis patients and scaling and root planing for chronic periodontitis patients. Gingival crevicular fluid (GCF was collected, and the presence of herpes simplex virus-1 (HSV-1, HSV-2, cytomegalovirus, and Epstein–Barr virus (EBV was analyzed using polymerase chain reaction (PCR. Recording of periodontal parameters as well as GCF collection was performed at baseline and 6 weeks postphase-I therapy. Results: At baseline, the levels of HSV-1 and EBV detection were lower in healthy controls as compared to gingivitis (P < 0.05 and chronic periodontitis cases (P < 0.001. Phase-I therapy led to reduction in the amount of HSV-1 and EBV in gingivitis patients (P < 0.05 and for HSV-1, human cytomegalovirus and EBV in chronic periodontitis patients (P < 0.05 in comparison to baseline. The prevalence of EBV in chronic periodontitis patients was positively associated with increased gingival index, probing depth and loss of clinical attachment (P < 0.05. Conclusions: Higher prevalence of HSV-1 and EBV viruses in GCF of gingivitis and chronic periodontitis suggests a strong association between these viruses and periodontal diseases and periodontal therapy can lead to a reduction in herpesviruses at infected sites.

    The evidence for an association between systemic diseases and periodontitis is strongest with diabetes mellitus type 2 and cardiovascular disease. There is a moderate association of periodontitis with adverse pregnancy outcomes and rheumatoid arthritis. Periodontal treatment has, on average, a positive effect on reducing systemic infection and improving the condition of the vascular system. For diabetes patients, periodontal treatment can also have a positive effect on metabolic regulation. There is insufficient evidence that periodontal treatment prevents adverse pregnancy outcomes and rheumatoid arthritis. PMID:26465017

    Full Text Available BACKGROUND &OBJECTIVES : Malodour has been correlated with the concentration of volatile sulphur compounds produced in the oral cavity by metabolic activity of bacteria colonizing the periodontal sites and the dorsum of the tongue. The aim of this study was to detect malodour in mouth air organoleptically and using a portable sulphide monitor and to correlate it with the clinical parameters, halitosis linked toxins and BANA, using tongue and subgingival plaque samples. The halitosis grading is also correlated with the microbial colonies of the subgingival plaque sample. METHODS : 20 patients with chronic periodontitis with 5-7 mm pocket depth, radiographic evidence of bone loss and presence of oral malodour participated in this study. Assessment of mouth air was done organoleptically and by using a portable sulphide monitor. The clinical parameter, plaque index (PI, gingival index (GI, gingival bleeding index (BI, were obtained from all the areas. Samples for BANA and to detect halitosis linked toxins were taken from the dorsal surface of the tongue and periodontal pockets ranging 5-7 mm. Halitosis related microbial colonies were identified using anaerobic culturing from the subgingival plaque. RESULTS : The scores of PI, GI, BI and sample that tested positive for halitosis linked toxins and with the halitosis grading were not significant. The presence of tongue coating and the halitosis grading and toxin levels were significant. BANA has shown to be non contributory due to technical problems. Anaerobic culture has shown to identify Streptococcus, Bacteroides, Fusobacterium, Porphyromonas and Prevotella colonies. INTERPRETATION &CONCLUSION : The results confirmed that there was no correlation between the clinical parameters, halitosis linked toxins and halitosis grading. The microbial colonies have shown to correlate with the presence of oral malodour.

    Full Text Available The research goal is to determine risk factors of periodontal disease development, psychophysiological personal types and their interrelations in clinically healthy persons. 47 first-year cadets of St.-Petersburg Military School of radio electronics have been examined. This group of respondents has been chosen by presence of such social stressor as change of place of living (97,9% cadets have arrived in St.-Petersburg from other cities and republics of the Russian Federation and strict disciplinary conditions. The research has revealed a low level of oral hygiene, cases of mild gingivitis in most respondents. The general mental state of group under study is characterized by raised level of personal anxiety and low indices of reactive anxiety. The examined group has demonstrated anxiety, tension, indecision and lowered stress stability. Clinically healthy persons are more liable to develop inflammatory and inflammatory-destructive periodontal diseases. It was possible to determine psychophysiological features correlated with physiological parameters of risk degree of periodontal diseases. It may have a great significance in defining of periodontal disease etiology and pathogenesis

  19. Quantitative molecular detection of putative periodontal pathogens in clinically healthy and periodontally diseased subjects.

    Directory of Open Access Journals (Sweden)

    André Göhler

    Full Text Available 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.

    In clinical diagnostic procedures, gingival inflammation is considered as the initial stage of periodontal breakdown. This is often detected clinically by bleeding on probing as it is an objective measure of inflammation. Since conventional diagnostic procedures have several inherent drawbacks, development of novel non-invasive diagnostic techniques assumes significance. This clinical study was carried out in 15 healthy volunteers and 25 patients to demonstrate the applicability of diffuse reflectance (DR) spectroscopy for quantification and discrimination of various stages of inflammatory conditions in periodontal disease. The DR spectra of diseased lesions recorded using a point monitoring system consisting of a tungsten halogen lamp and a fiber-optic spectrometer showed oxygenated hemoglobin absorption dips at 545 and 575 nm. Mean DR spectra on normalization shows marked differences between healthy and different stages of gingival inflammation. Among the various DR intensity ratios investigated, involving oxy Hb absorption peaks, the R620/R575 ratio was found to be a good parameter of gingival inflammation. In order to screen the entire diseased area and its surroundings instantaneously, DR images were recorded with an EMCCD camera at 620 and 575 nm. We have observed that using the DR image intensity ratio R620/R575 mild inflammatory tissues could be discriminated from healthy with a sensitivity of 92% and specificity of 93%, and from moderate with a sensitivity of 83% and specificity of 96%. The sensitivity and specificity obtained between moderate and severe inflammation are 82% and 76% respectively.

    Patients treated with adrenal glucocorticoids may run a higher risk of dental caries, both as a result of their medical condition and of the physical and physiological effects of their pharmacotherapy. Our clinical study reports about patients treated with glucocorticoids who were also having an odonto-periodontal condition. They were examined and we found rampant caries and periodontal diseases. The slow evolution of asymptomatic periodontal disease encouraged destruction of teeth in root caries. The rampant caries were correlated with immunodeficiency and treatment of these caries must take into account the general treatment.

    Background. Transferrin is a negative acute phase protein, which decreases during inflammation and infection. The aim of the present investigation was to evaluate changes in the transferrin serum levels subsequent to non-surgical treatment of chronic periodontal disease. Methods. Twenty patients with chronic periodontitis and 20 systemically healthy subjects without periodontal disease, who had referred to Tabriz Faculty of Dentistry, were selected. Transferrin serum levels and clinical periodontal parameters (pocket depth, clinical attachment level, gingival index, bleeding index and plaque index) were measured at baseline and 3 months after non-surgical periodontal treatment. Data were analyzed with descriptive statistical methods (means ± standard deviations). Independent samples t-test was used to compare transferrin serum levels and clinical variables between the test and control groups. Paired samples t-test was used in the test group for comparisons before and after treatment. Statistical significance was set at P periodontitis (213.1 ± 9.2 mg/dL) was significantly less than that in periodontally healthy subjects (307.8 ± 11.7 mg/dL). Three months after periodontal treatment, the transferrin serum level increased significantly (298.3 ± 7.6 mg/dL) and approached the levels in periodontally healthy subjects (P periodontal disease and periodontal treatment, respectively, indicated an inverse relationship between transferrin serum levels and chronic periodontitis.

    The purpose of this study was to compare the use of bioactive glass to demineralized freeze-dried bone allograft (DFDBA) in the treatment of human periodontal osseous defects. Fifteen systemically healthy patients (6 males and 9 females, aged 30 to 63) with moderate to advanced adult periodontitis were selected for the study. All patients underwent initial therapy, which included scaling and root planing, oral hygiene instruction, and an occlusal adjustment when indicated, followed by re-evaluation 4 to 6 weeks later. Paired osseous defects in each subject were randomly selected to receive grafts of bioactive glass or DFDBA. Both soft and hard tissue measurements were taken the day of surgery (baseline) and at the 6-month re-entry surgery. The clinical examiner was calibrated and blinded to the surgical procedures, while the surgeon was masked to the clinical measurements. Statistical analysis was performed by using the paired Student's t test. The results indicated that probing depths were reduced by 3.07 +/- 0.80 mm with the bioactive glass and 2.60 +/- 1.40 mm with DFDBA. Sites grafted with bioactive glass resulted in 2.27 +/- 0.88 mm attachment level gain, while sites grafted with DFDBA had a 1.93 +/- 1.33 mm gain in attachment. Bioactive glass sites displayed 0.53 +/- 0.64 mm of crestal resorption and 2.73 mm bone fill. DFDBA-grafted sites experienced 0.80 +/- 0.56 mm of crestal resorption and 2.80 mm defect fill. The use of bioactive glass resulted in 61.8% bone fill and 73.33% defect resolution. DFDBA-grafted defects showed similar results, with 62.5% bone fill and 80.87% defect resolution. Both treatments provided soft and hard tissue improvements when compared to baseline (P < or = 0.0001). No statistical difference was found when comparing bioactive glass to DFDBA; however, studies with larger sample sizes may reveal true differences between the materials. This study suggests that bioactive glass is capable of producing results in the short term (6 months

    Background Various studies have shown that non-surgical periodontal treatment is correlated with reduction in clinical parameters and plasma levels of inflammatory markers. The aim of this study was to evaluate the effect of long-term weekly supragingival irrigations with aerosolized 0.5% hydrogen peroxide as maintenance therapy followed by non-surgical periodontal treatment on clinical parameters, plasma levels of inflammatory markers, and morphological changes in gingival tissues of patients with periodontitis. Material/Methods In total, 43 patients with chronic periodontitis were randomly allocated to long-term maintenance therapy. The patients’ periodontal status was assessed using clinical parameters of approximal plaque index, modified gingival index, bleeding index, pocket probing depth, and plasma levels of inflammatory markers (high-sensitivity C-reactive protein and white blood cell count) at baseline and after 1, 2, and 3 years. The morphological status of gingival tissues (immediately after supragingival irrigation) was assessed microscopically. Results Complete data were obtained on 34 patients. A highly statistically significant and consistent reduction was observed in all long-term clinical parameters and plasma levels of inflammatory markers. Morphological data showed abundant spherical bubbles in gingival tissues. Conclusions 1. The present study showed that non-surgical periodontal treatment with long-term weekly supragingival irrigations with aerosolized 0.5% hydrogen peroxide improved clinical periodontal status and plasma levels of inflammatory markers and may be a promising method in periodontology. 2. We found that supragingival irrigation with aerosolized 0.5% hydrogen peroxide created large numbers of spherical bubbles in gingival tissues. PMID:27743448

    Holographic evaluations count among recent measurement tools in orthodontics and prosthodontics. This research introduces holography as an assessment method of 3D variations of gingival retractions. The retraction of gingiva on frontal regions of 5 patients with periodontitis was measured in six points and was evaluated by holographic methods using a He-Ne laser device (1mV, Superlum, Carrigtwohill, Ireland) inside a holographic bank of 200 x 100cm. Impressions were taken during first visit and cast models were manufactured. Six months after the end of periodontal treatment, clinical measurements were repeated and the hologram of the first model was superimposed on a final model cast, by using reference points, while maintaining the optical geometric perimeters. The retractions were evaluated 3D in every point using a dedicated software (Sigma Scan Pro,Systat Software, SanJose, CA, USA). The Wilcoxon test was used to compare the mean recession changes between baseline and six months after treatment, and between values in vivo and the values on hologram. No statistically significant differences between values in vivo and on the hologram were found. In conclusion, holography provides a valuable tool for assessing gingival retractions on virtual models. The data can be stored, reproduced, transmitted and compared at a later time point with accuracy.

    We investigated the outcome of conventional periodontal treatment in mouth breathing patients with chronic periodontitis, and compared the efficacy of applying salivary substitute to the anterior sextants as an adjunct to conventional treatment in such patients. In this randomized, investigator-blind, clinical study involving parallel groups, 40 mouth breathing patients were divided into two groups: a control group (CG, n = 20) comprising patients who received scaling and root planing (SRP), and a test group (TG, n = 20) who received salivary substitute as an adjunct to SRP for treatment of chronic periodontitis. The patients were followed up at various time intervals, and improvement of the gingival index (GI) was examined as the primary outcome. Student's t-test, repeated-measures ANOVA and Mann-Whitney U test were applied for statistical analysis. Although periodontal parameters were improved in both groups after 8 weeks of follow-up, the test group showed better improvement in terms of GI and percentage bleeding on probing. Within the limits of this study, our results suggest that the use of salivary substitute has a beneficial adjunctive effect for improvement of periodontal parameters in mouth breathing patients with chronic periodontitis.

    Summary Aim Hydroxyapatite (PA) has a chemical composition and physical structure very similar to natural bone and therefore it has been considered to be the ideal biomaterial able to ensure a biomimetic scaffold to use in bone tissue engineering. The aim of this study is to clinically test hydroxyapatite used as osteoconductive biomaterial in the treatment of periodontal bone defects. Clinical and radiological evaluations were conducted at 6, 12 and 18 months after the surgery. Materials and methods Forty patients with 2- and 3-wall intrabony pockets were enrolled in this study. PPD, CAL, radiographic depth (RD) and angular defects were preoperatively measured. After surgery, patients were re-evaluated every 6 months for 18 months. Statistical analyses were also performed to investigate any differences between preoperative and postoperative measurements. Results Paired t-test samples conducted on the data obtained at baseline and 18 months after, showed significant (p<0.01) differences in each measurement performed. The role of preoperative RD was demonstrated to be a significant key factor (p<0.01). A relevant correlation between preoperative PPD and CAL gain was also found. Conclusions Within the limitations of this study, the absence of anatomical variables, except the morphology of the bone defect, emphasizes the importance of the proper surgical approach and the graft material used.

    New data indicate that periodontal diseases are much more prevalent than previously thought, which means that there are large numbers of patients who will need to be diagnosed and treated for periodontal disease in a general dental practice. Oral hygiene procedures performed by patients between office visits are important for gingival health. No particular type of toothbrush has consistently been shown to have superior plaque-removal ability over another. Although studies on powered brushes have shown evidence for efficacy of biofilm removal and increased patient compliance, they are of short duration, making evaluation of long-term effects difficult to achieve. Interdental cleaning with dental floss can be effective but it is technique-sensitive. Interdental brushes have been shown to be superior to floss in plaque index scores, but not in gingival inflammation reduction. A systematic review of oral irrigation reported a beneficial adjunctive effect on bleeding and gingival indices and pocket depth. Antimicrobials in mouthrinses and toothpastes have shown significant reductions in plaque and gingivitis when used correctly. Even though it is considered essential for patients to utilize biofilm-removal techniques on a frequent basis, studies on adherence show that approximately 30-60% of health information is forgotten within 1 h, and 50% of health recommendations are not followed. Incorporating psychosocial aspects of behavioral change, including well-established counseling strategies, such as motivational interviewing, may elicit improved patient outcomes. PMID:27045431

    Full Text Available Abstract 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

    Statement of the Problem The presence of bacterial biofilms is the major cause of gingivitis and periodontitis, their mechanical removal is not often enough. Therefore, laser therapy and photodynamic therapy can be effective as adjunctive treatment. Purpose This study aimed to evaluate the impact of these treatments on the level of gingival crevicular fluid (GCF), inflammatory mediators, and periodontal clinical status. Materials and Method In this clinical trial, three quadrants were studied in 12 patients with chronic periodontitis aged 30-60 years. The clinical parameters were recorded and GCF samples were taken. After the first phase of periodontal treatment, one of the three quadrants was determined as the control group, one was treated by diode laser, and one underwent photodynamic therapy. The clinical parameters were recorded 2 and 6 weeks later. The data were statistically analyzed by using Friedman, ANOVA, and LSD post-test. Results Significant reduction was observed over time in the level of Interleukin-1β (IL-1β), Interleukin-17 (IL-17), clinical attachment loss, and pocket depth in the three treatment groups (plaser and photodynamic therapy significantly decreased the average bleeding on probing over time (pLaser and photodynamic therapy reduced the inflammatory mediators (IL-1β and IL-17) and improved the clinical symptoms.

  7. Clinical Relevance of the Advanced Microbiologic and Biochemical Investigations in Periodontal Diagnosis: A Critical Analysis

    Directory of Open Access Journals (Sweden)

    Vishakha Grover

    2014-01-01

    Full Text Available New approaches to periodontal diagnosis, including advanced microbiologic, biochemical, and genetic tests, have been shown to provide the clinician with the information not available by traditional means. The purpose of a diagnostic test is to confirm, exclude, classify, or monitor disease to guide treatment. Their clinical value depends on whether the information they provide leads to improved patient outcomes. This can be assessed by randomized trials, which compare patient outcomes from the new diagnostic test versus the old test strategy. Being nonmandatory for marketing approval, such trials are not always feasible because of large sample sizes requirements. So, many diagnostic tests enter the practice without being critically analysed for any additional benefits. Effective diagnosis is just as essential as the selection of effective treatments for the success of periodontal therapy. So, the current paper aims to focus on the practical utility of this rapidly emerging plethora of periodontal diagnostic tools, emphasizing the critical issues surrounding the clinical application of microbiologic and biochemical investigations, employed for periodontal diagnosis.

    Full Text Available Background: Recent developments suggest that the local delivery of antimicrobials into periodontal pockets can improve periodontal health. Azithromycin (AZM has a wide antimicrobial spectrum of action toward anaerobic bacteria as well as Gram-negative bacilli. It is effective against periodontal pathogens such as Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis. Therefore, this study was undertaken to investigate the clinical effectiveness of AZM at 0.5% concentration in an indigenously prepared bioabsorbable controlled release gel as an adjunct to non-surgical mechanical therapy in the treatment of chronic periodontitis. Materials and Methods: Thirty sites in patients with chronic periodontitis and probing depth (PD 4-6 mm were categorized randomly into two treatment groups: Scaling and root planing (SRP plus 0.5% AZM gel (group 1 and SRP only (group 2. Clinical evaluation was undertaken using the Gingival Index (GI of Loe and Silness and plaque was assessed using the Turesky et al. modification of Quigley Hein Index at baseline and 21 days. Pocket PD and clinical attachment level (CAL were also measured. Statistical Analysis: Results were expressed as mean ± standard deviation and percentages and the data were analyzed using Statistical Package for Social Sciences (SPSS version 16.0, SPSS, Chicago, IL software. Result: Both therapies resulted in significant improvements. Mean reduction in GI from baseline to 21 days was 1.20 ± 0.41 and 0.73 ± 0.45 in group 1 and group 2, respectively. Plaque Index also improved through the study period in both groups, i.e., 0.86 ± 0.51 in group 1 and 1.6 ± 0.97 in group 2. Mean PD reduced significantly with SRP plus AZM gel application in group 1, i.e., 2.1 ± 0.91 mm as compared to 1.0 ± 1.06 mm achieved with SRP alone. A significant gain in mean CAL gain was observed in the test group (1.8 ± 0.63 mm as compared to control group (1.0 ± 1.06 mm. Conclusion: Although both treatment

    2013-02-01

    Since conventional techniques using periodontal probes have inherent drawbacks in the diagnosis of different grades of gingival inflammation, development of noninvasive screening devices becomes significant. Diffuse reflectance (DR) spectra recorded with white light illumination is utilized to detect periodontal inflammation from the oxygenated hemoglobin absorption ratio R620/R575. A multispectral imaging system is utilized to record narrow-band DR images at 575 and 620 nm from the anterior sextant of the gingivia of 15 healthy volunteers and 25 patients (N=40). An experienced periodontist assesses the level of gingival inflammation at each site through periodontal probing and assigns diagnosis as healthy, mild, moderate, or severe inflammation. The DR image ratio R620/R575 computed for each pixel (8-μm resolution) from the monochrome images is pseudo-color-mapped to identify gingival inflammation sites. The DR image ratio values at each site are compared with clinical diagnosis to estimate the specificity and sensitivity of the DR imaging technique in inflammation mapping. The high diagnostic accuracy is utilized to detect underlying inflammation in six patients with a previous history of periodontitis.

    Full Text Available To make distinct approaches in the diagnosis, treatment and prevention of chronic generalized periodontitis the analysis of case rate of the disease during the period of 2010-2012 years was carried out in the dental clinic of Krasnoyarsk State Medical Academy. In order to divide patients into several groups according to severity of the disease the review of case history of 4390 patients aged 20 to 65 was made. 684 patients (15.6 % were diagnosed with mild degree of the disease, 2608 (59.4% with an average degree and 1908 patients (25% with severe degree of the disease. The low percentage of number of patients with mild degree of the disease is the result of late diagnosis of the disease. During the analysis of the structure of providing periodontal care at the stages of examination, periodontal and surgical help the lack of an objective assessment of the condition ofalveolar mucosa isnoted. Therefore, during the initial examination, we suggest to use Schiller-Pisarev method. As a crucial step in the identification of early forms of periodontal disease is a health education outreach.

    Full Text Available Background: Growth of scientific evidence suggests an exquisite association between oral infection and systemic diseases. Though etiologies of periodontitis and rheumatoid arthritis (RA are separate, their underlying pathological processes are sufficient to warrant consideration of hypothesis that individuals at risk of developing RA may also be at the risk of developing periodontitis and vice versa. Materials and Methods: To test their relationship, a study was carried out on 80 individuals. Part A: Forty subjects having rheumatoid arthritis (RA group were compared to 40 controls without arthritis (NRA group. Their periodontal indices rheumatoid arthritis clinical laboratory parameters were also correlated with periodontitis in group. Part B: Omplete periodontal treatment was done for 10 patients of group suffering from periodontitis. All parameters of periodontal indices were measured pre-operatively and weeks after completion of periodontal treatment. Results: (1 There was high prevalence of mild (12.5% to moderate (75% periodontitis in group. (2 Extent severity of periodontal disease rheumatoid arthritis were positively correlated. (3 Statistically significant differences were present in periodontal parameters of RA group compared to NRA group. (4 There was statistically, significant reduction in parameters postoperatively with concomitant decrease in periodontal parameters in RA group. Conclusion: Thus, an association exists between periodontal disease with an underlying dysregulation of the molecular pathways in the inflammatory response. Also, there are significant management implications in the future as new host modifying medications are developed.

    Full Text Available Background and Objective: Transmucosal analgesic delivery is a promising approach to periodontal postoperative pain management. The purpose of this clinical trial is to appraise the effectiveness of transmucosal drug delivery system with meloxicam films and to identify its minimum effective dosage via this route after periodontal flap surgery. Materials and Methods: The analgesic mucoadhesive films were formulated using meloxicam and hydroxypropyl methyl cellulose polymer by solvent casting method. The sample size consisted of 60 chronic periodontitis patients who require periodontal flap surgery. The subjects were randomized using lottery method into four groups (Group A - 45 mg; B - 30 mg; C - 20 mg; D - 10 mg meloxicam per film. After periodontal flap surgery, the respective meloxicam mucoadhesive films were placed over the surgical site and were removed on 4 th day of postsurgery. The primary outcome measure was postsurgical pain level and recorded at 1 st , 2 nd , 3 rd , 4 th , 5 th , 24 th , and 48 th h using a 0-10 mm visual analog scale with markings from 0 = no pain to 10 = extreme pain. Results: The postoperative pain control observed in Groups A and B was found to be effective, and the patient comfort level was very satisfactory. Whereas in Group C, it was found to be high in the first 3 h postsurgically, after which adequate pain relief was seen. Group D exhibited inadequate pain relief. No adverse reactions were noted after applying the film in any of the groups. Conclusion: Transmucosal delivery of meloxicam was found to be effective and safe in postsurgical pain control of periodontal flap surgery. The minimum effective dosage via this route for meloxicam was found to be with 30 mg mucoadhesive films.

    Full Text Available Periodontitis comprises a group of multifactorial diseases in which periodontopathogens accumulate in dental plaque and trigger host chronic inflammatory and immune responses against periodontal structures, which are determinant to the disease outcome. Although unusual cases of non-inflammatory destructive periodontal disease (NIDPD are described, their pathogenesis remains unknown. A unique NIDPD case was investigated by clinical, microbiological, immunological and genetic tools. The patient, a non-smoking dental surgeon with excessive oral hygiene practice, presented a generalized bone resorption and tooth mobility, but not gingival inflammation or occlusion problems. No hematological, immunological or endocrine alterations were found. No periodontopathogens (A. actinomycetemcomitans, P. gingivalis, F. nucleatum and T. denticola or viruses (HCMV, EBV-1 and HSV-1 were detected, along with levels of IL-1β and TNF-a in GCF compatible with healthy tissues. Conversely ALP, ACP and RANKL GCF levels were similar to diseased periodontal sites. Genetic investigation demonstrated that the patient carried some SNPs, as well HLA-DR4 (*0404 and HLA-B27 alleles, considered risk factors for bone loss. Then, a less vigorous and diminished frequency of toothbrushing was recommended to the patient, resulting in the arrest of alveolar bone loss, associated with the return of ALP, ACP and RANKL in GCF to normality levels. In conclusion, the unusual case presented here is compatible with the previous description of NIDPD, and the results that a possible combination of excessive force and frequency of mechanical stimulation with a potentially bone loss prone genotype could result in the alveolar bone loss seen in NIDPD.

    Full Text Available tatement of Problem: Although mechanical debridement is considered as the conventional technique in the management of chronic periodontitis, the locally delivered antiseptic agents have also been investigated as an adjunctive therapy. Purpose: The purpose of this study was to investigate the clinical effectiveness of subgingival irrigation with polyvinylpyrrolidone-Iodine (PVP-I 10%, H2O2 3%, and the combination of both in the measurement of probing depth and plaque and gingival indices of patients with moderate to severe chronic periodontitis. Materials and Method: In this double-blind randomized clinical trial, 16 patients with moderate to severe periodontitis were selected using the simple random sampling method. They had at least one tooth with a probing depth ≥5 mm in each quadrant and had undergone phase I of periodontal therapy one month after dental scaling, The initial probing depth, plaque, and gingival indices were recorded and the selected teeth were randomly irrigated with PVP-I 10%, H2O2 3%, H2O2 3% + PVP-I 10%, or normal saline. The measurements were repeated five weeks after the procedure. The data were analyzed through running paired-samples t-test, analysis of variance (ANOVA, Wilcoxon Signed Rank Test, and Kruskal-Wallis Test. Results: The mean differences in probing depth before and after subgingival irrigation in patients who were treated with normal saline, H2O2, PVP-I, and PVP + H2O2 were 1.29 mm, 1.35 mm, 1.47 mm, and 1.71 mm, respectively. This indi-cated a significant difference among all the groups ( p <05(. Furthermore, PVP-I had a positive effect on the gingival index but it had no significant effect on the plaque index. Conclusion: Subgingival irrigation is an effective adjunctive therapy to mechanical debridement in treating moderate to severe chronic periodontitis.

    Full Text Available This study was undertaken to evaluate the effect of oral administration of lactoferrin (LF and lactoperoxidase-(LPO-containing tablet on periodontal condition. Seventy-two individuals with chronic periodontitis were randomly assigned to take either bovine LF and LPO-containing tablets (test group, n=37 or control tablets (control group, n=35 every day for 12 weeks. Periodontal parameters and levels of subgingival plaque bacteria, human and bovine LF, and endotoxin in gingival crevicular fluid (GCF were evaluated at baseline, 1 week, 4 weeks, and 12 weeks. Significant differences were observed in GCF levels of bovine LF between the test and control groups throughout the study (P<.05. However, clinical and bacteriological parameter values proved comparable between the two groups at 1 week to 12 weeks. Therefore, the effect of oral administration of LF and LPO-containing tablets might be weak on periodontal and bacteriological profile in this study.

    Full Text Available Background and Objectives: The evaluation of gingival margin position (GMP plays a vital role in periodontal therapy and is critical in esthetic/plastic surgical procedures revolving around restorative dentistry. Comparative evaluations of GMP measurements in various periodontal therapies are scarce. Thus, the objectives of this study are to measure the alteration in the gingival margin position following various therapies, and to compare GMP alterations among different treatment modalities from the baseline to six months after therapy. Materials and Methods: The changes in GMP were studied for MB, B, DB, ML, and L sites for SRP, curettage, and flap surgery, and for MB, B, and DB sites for crown lengthening cases at the end of one, three, and six months after therapy. The results were interpreted from baseline to one, three, and six months posttreatment. Statistical Analysis : The results were subjected to statistical analysis. Paired ′t′-test was used for intra-group comparisons and intergroup comparisons were done by one-way ANOVA. Results: The GMP changed from baseline in all the sites at different time periods following various therapies. The net results after six months were an apical shift of GMP in SRP, curettage, and flap surgery, and a coronal shift of GMP in crown lengthening. Conclusion: GMP shows various patterns of alteration after various periodontal therapies. One should wait for the GMP to become stable before attempting any restorative procedure.

    Full Text Available Background: The systemic use of non-steroidal anti-inflammatory drugs are associated with various side-effects like hepatotoxicity, blood dyscrasias, nephrotoxicity and gastric irritability. Among these, gastric irritability is the most common and the most important one, which should be taken care of. Therefore, it may be preferable to use a local formulation such as a mouthwash to treat the inflammatory conditions of the oral cavity. Aim: To determine the efficacy and acceptability of 0.074% diclofenac mouthwash in relieving pain and inflammation of post-periodontal surgery patients. Materials and Methods: The study was designed as a double-blind, placebo-controlled clinical trial. Twenty chronic periodontitis patients who were scheduled for full-mouth periodontal flap surgery were randomized to receive either diclofenac mouthwash or placebo to rinse with 15 ml of solution daily for a period of 7 days. Modified gingival index (Lobene 1986 was used to verify gingival inflammation and visual analog scale was used to assess pain. After the baseline measurements for all the parameters were recorded, spontaneous pain and burning were evaluated daily while redness and edema were recorded on the 3 rd and 7 th day from the day of treatment. Results: Data obtained were analyzed statistically using paired " t" test for intragroup comparison and unpaired " t"-test for intergroup comparison. Spontaneous pain was significantly reduced by diclofenac mouthwash. Other parameters, i.e. gingival inflammation and swelling, had not shown significant reduction in scores in either group, although the reduction was higher in the test group. Conclusion: The new 0.074% diclofenac mouthwash is an effective and tolerable medicinal product for post-surgical symptomatic relief.

    Objectives: The purpose of this study was to analyze how anti-infectious periodontal treatment affects C reactive protein (CRP) values in patients with type 1 diabetes, and correlate baseline CRP levels with periodontal disease severity. Study Design: A cohort of fifty three subjects with type 1 diabetes and moderate to severe periodontitis were recruited. Periodontal parameters were measured, and blood samples were obtained to evaluate high-sensitivity C-reactive protein (hs-CRP). Group 1 was treated with scaling, root planning, and systemic administration of doxycycline. Group 2 received only scaling and root planning. Results: Hs-CRP was reduced after periodontal treatment in group 1 (-0.22 mg/l) and 2 (-0.21 mg/l ) but this reduction was not statistically significant, even in the patients with the best response to periodontal treatment. However, significant correlation appeared between hs-CRP and mean probing pocket depth (PPD) (p=0, 01) and mean clinical attachment level (CAL) (p=0,03). Conclusions: Non-surgical periodontal treatment couldn’t reduce hs-CRP values, however, it was found an association between advanced periodontitis and elevated blood hs-CRP levels in patients with type 1 diabetes. It can be speculated that periodontal disease increases production of pro-inflammatory mediators in patients with type 1 diabetes, but other producing sources of these pro-inflammatory substances may exist.

    Evolution of periodontal disease is one of the most important data for the clinicians in order to achieve correct planning and treatment. Clinical measure of the periodontal sulcus depth is the most important datum to know the exact state of periodontal disease. These measures must be done periodically study bone resorption evolution around teeth. Time factor of resorption indicates aggressiveness of periodontitis. Manual probes are commonly used with direct reading. Mechanical probes give automatic signal but this method uses complicated and heavy probes that are only limited for University researchers. Probe position must be the same to have right diagnosis. Digital image analysis of periodontal probing provides practical, accurate and easy tool. Gum and plaque index could also be digitally measured with this method.

    Introduction The primary goal in periodontal therapy includes removal of the etiological factors by mechanical periodontal treatment, which sometimes fail to eliminate the anaerobic infection at the base of the pocket and requires adjuvant chemical therapy. Aim The aim of the study was to evaluate the effectiveness of 2% minocycline ointment when used as an adjunct to periodontal flap surgery and post-operative maintenance period for the treatment of generalized chronic periodontitis. Materials and Methods The study included 30 subjects comprising of 60 posterior sextants in a split mouth design in which 30 sextants were treated as experimental and 30 sextants as control with a probing pocket depth≥6mm. In Group A (experimental group) 30 sextants were treated with open flap debridement followed by the application of minocycline ointment as a local drug delivery. In Group B (control group) 30 sextants were treated with open flap debridement alone. Minocycline hydrochloride ointment was applied on the 0 day and 3rd month. The clinical parameters such as plaque index, probing pocket depth, clinical attachment level and gingival bleeding index were recorded at 0 day, 3rd month and 6th month in both the groups. Paired and unpaired t-test were used to compare the means of the two groups. Results When Group A and Group B were compared, Group A showed significantly greater reduction in gingival bleeding index, probing pocket depth and gain in clinical attachment level than Group B, from 0 day to 3 months and from 0 day to 6 months. Group A showed significant reduction in plaque index than Group B when they were compared at 6 months. Conclusion The results demonstrate that there was significant reduction in the clinical parameters with improvement in the periodontal status on application of minocycline ointment as an adjunct to periodontal flap surgery in generalized chronic periodontitis.

    planning. Methods: Clinical parameters were measured and bacterial samples were collected from 44 sites in 11 patients with chronic periodontitis. By means of Polymerase Chain Reaction (PCR the presence of Aggregatibacter actinomycetemcomitans (Aa, Porphyromonas gingivalis (Pg, Treponema denticola (Td, Tannerella forsythia (Tf and Prevotella intermedia (Pi was estimated. The patients received mechanical periodontal therapy and were evaluated after 1 week, 3 months and 12 months. Results: After treatment, all clinical parameters (Plaque, Bleeding on Probing, Supuration, Probing Pocket Depth and Clinical Attachment Level were significantly reduced, and the values obtained were maintained up to the 12 months that the study lasts. At baseline, the most prevalent species were Pg, present in 66% of the sites, Tf (55% and Td (41%. The deepest sites were related to the association Tf-Td (6.8 mm and Tf-Td-Pi (7 mm. The number of positive sites for Td, Tf and Pg was significantly reduced after therapy. Conclusions: Scaling and root planning improve significantly clinical parameters as well as reduce the prevalence of periodontal pathogens Pg, Td and Tf in deep periodontal pockets. The results obtained were maintained up to 12 months. No further clinical attachment loss was found in 86% of the sites at 3 months and 79% at 12 months. The sites where the treatment failed in removing pathogens developed at 12 months greater probing pocket depths.

    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.

    Full Text Available The paper presents the results of a comparative study of microbial landscape features in patients with generalized periodontitis at pre-clinical and radiological stage of its development in 42 patients. The purpose of the study is a comparative study of the composition of microbiocenosis of periodontal tissues in patients with chronic catarrhal gingivitis (CCG and chronic generalized periodontitis (CGP at an early stage of development and development studies of microbiological criteria for early emergence of the destructive process in periodontal structures. We found that the microflora isolated from dento-gingival grooves is of importance in diagnostics to identify the etiology of chronic generalized catarrhal gingivitis (CGCG and chronic generalized periodontitis in the early stages of its development. It was established that the presence of two or more types of fixed parodonto-pathogenic microorganisms in microbial association increases the likelihood of inflammatory and destructive events in periodontal tissues in patients with GCCG and is one of the reasons of is becoming CGP.

    Full Text Available Objectives: Fixed orthodontic appliances make daily application of oral hygiene standard procedures more difficult and in time may lead to accumulation of oral biofilms and development of gingivitis and hyperplasia. The aim of the study is to evaluate the periodontal health expressed by clinical indices in patients under orthodontic treatment with fixed appliances, according to different oral hygene maintenance programs. Material and method: We performed a randomized prospective study on 60 patients with fixed orthodontic appliances (17-25 years of age devided in three study groups. The clnical indices recorded were: modified gingival index, plaque index and sulcular bleeding index. Statistical analysis or the results were carried out using Student t test. Results: The patients were randomly divided into three groups: group A-patients were instructed to use electric brush, water flosser and interdental brush, group B- electric brush, interdental brush and fluoride and group C- manual brushing and fluoride. Statistical comparison of the values of the indexes with the Student t test for independent samples showed statistically significant differences in all three groups of patients studied between initial and final values of all recorded clinical parameters. Conclusions: Fixed orthodontics do not induce periodontal disease if basic principles of oral hygiene are followed in compliant patients, which are correctly instructed to deal with real challenge, represented by complete elimination of debris and bacterial accumulation.

    The periodontal ligament is a complex tissue with respect to its biomechanical behaviour. It is important to understand the mechanical behaviour of the periodontal ligament during physiological loading in healthy patients as well as during the movement of the tooth in orthodontic treatment or in patients with periodontal disease, as these might affect the mechanical properties of the periodontal ligament (PDL). Up to now, only a limited amount of in vivo data is available concerning this issue. The aim of this study has been to determine the time dependent material properties of the PDL in an experimental in vivo study, using a novel device that is able to measure tooth displacement intraorally. Using the intraoral loading device, tooth deflections at various velocities were realised in vivo on human teeth. The in vivo investigations were performed on the upper left central incisors of five volunteers aged 21-33 years with healthy periodontal tissue. A deflection, applied at the centre of the crown, was linearly increased from 0 to 0.15mm in a loading period of between 0.1 and 5.0s. Individual numerical models were developed based on the experimental results to simulate the relationship between the applied force and tooth displacement. The numerical force/displacement curves were fitted to the experimental ones to obtain the material properties of the human PDL. For the shortest loading time of 0.1s, the experimentally determined forces were between 7.0 and 16.2N. The numerically calculated Young's modulus varied between 0.9MPa (5.0s) and 1.2MPa (0.1s). By considering the experimentally and numerically obtained force curves, forces decreased with increasing loading time. The experimental data gained in this study can be used for the further development and verification of a multiphasic constitutive law of the PDL. PMID:26395824

    Self-report is an efficient and accepted means of assessing many population characteristics, risk factors, and diseases, but has rarely been used for periodontal disease (chronic periodontitis). The availability of valid self-reported measures of periodontal disease would facilitate epidemiologic studies on a much larger scale, allow for integration of new studies of periodontal disease within large ongoing studies, and facilitate lower-cost population surveillance of periodontitis. Several studies have been conducted to validate self-reported measures for periodontal disease, but results have been inconsistent. In this report, we conducted a systematic review of the validation studies. We reviewed the 16 studies that assessed the validity of self-reported periodontal and gingivitis measures against clinical gold standards. Seven of the studies included self-reported measures specific to gingivitis, four included measures only for periodontitis, and five included both gingivitis and periodontal measures. Three of the studies used a self-assessment method where they provided the patient with a detailed manual for performing a self-exam. The remaining 13 studies asked participants to self-report symptoms, presence of periodontal disease itself, or their recollection of a dental health professional diagnosing them or providing treatment for periodontal disease. The review indicates that some measures showed promise, but results varied across populations and self-reported measures. One example of a good measure is, "Has any dentist/hygienist told you that you have deep pockets?", which had a sensitivity of 55%, a specificity of 90%, positive predictive value of 77%, and negative predictive value of 75% against clinical pocket depth. Higher validity could be potentially obtained by the use of combinations of several self-reported questions and other predictors of periodontal disease. PMID:16183785

    This study describes the formulation, characterisation and preliminary clinical evaluation of mucoadhesive, semi-solid formulations containing hydroxyethylcellulose (HEC, 1-5%, w/w), polyvinylpyrrolidine (PVP, 2 or 3%, w/w), polycarbophil (PC, 1 or 3%, w/w) and tetracycline (5%, w/w, as the hydrochloride). Each formulation was characterised in terms of drug release, hardness, compressibility, adhesiveness (using a texture analyser in texture profile analysis mode), syringeability (using a texture analyser in compression mode) and adhesion to a mucin disc (measured as a detachment force using the texture analyser in tensile mode). The release exponent for the formulations ranged from 0.78+/-0.02 to 1. 27+/-0.07, indicating that drug release was non-diffusion controlled. Increasing the concentrations of each polymeric component significantly increased the time required for 10 and 30% release of the original mass of tetracycline, due to both increased viscosity and, additionally, the unique swelling properties of the formulations. Increasing concentrations of each polymeric component also increased the hardness, compressibility, adhesiveness, syringeability and mucoadhesion of the formulations. The effects on product hardness, compressibility and syringeability may be due to increased product viscosity and, hence, increased resistance to compression. Similarly, the effects of these polymers on adhesiveness/mucoadhesion highlight their mucoadhesive nature and, importantly, the effects of polymer state (particularly PC) on these properties. Thus, in formulations where the neutralisation of PC was maximally suppressed, adhesiveness and mucoadhesion were also maximal. Interestingly, statistical interactions were primarily observed between the effects of HEC and PC on drug release, mechanical and mucoadhesive properties. These were explained by the effects of HEC on the physical state of PC, namely swollen or unswollen. In the preliminary clinical evaluation, a formulation

    chronic complications and possibly, death by diabetes. It is recognized that both diseases are related because the inflammation factors generated by the periodontitis as well as the oral cavity bacteria in the systemic circulation, may act as aggravating factor for insulin resistance and worsen the glycemic control. It is clear that an opportune treatment of PD would improve the quality of life and the metabolic control of diabetic patients. The objectives of the current paper are to evaluate the impact of the periodontal therapy in both clinical and metabolic parameters in type 2 diabetic and prediabetic obese patients and to demonstrate that uncontrolled diabetics can be treated successfully, without increasing their medical risk. Nine DM2 and 7 glucose intolerant obese patients were selected. All of them suffering severe chronic periodontitis. All patients were treated following a protocol designed by us and medical indications were not modified. The DM2 patients showed approximately a 1% decrease in HbA1C after 6 months of the periodontal treatment. No complication was observed and no patient needed major medical assistance. The response to the periodontal treatment was similar in both groups, with a significant improvement in clinical parameters. Although the decrease in HbA1C was not statistically significant, our results are very promising at the clinical setting.

    The purpose of the present study was to determine whether any of the clinical parameters recorded during an initial periodontal examination would relate to the course of periodontal cases maintained for long periods of time. Based on available documentation, cases which had a downhill course were assembled from a population previously studied. In addition, long-term cases currently under maintenance care were drawn from our private practice. On average, the patients had been under care for 23 years. The study population was heavily weighted toward downhill cases to better compare these cases with those usually found in periodontal practice. Positive statistical correlations were found between the amount of subgingival calculus and the degree of gingival inflammation at initial examination. Disease severity initially was positively correlated to long-term course of disease. The amount of subgingival calculus did not relate to the long-term result. There was a strong correlation between inflammatory gingival hyperplasia initially and good long-term maintenance. The results suggest that, in combination, initial characteristics of periodontal cases coupled with long-term results of treatment may aid in further subclassifying the periodontal diseases.

    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 Abstract Background Oral hygiene education is central to every stage of periodontal treatment. Successful management of periodontal disease depends on the patient's capacity for oral self-care. In the present study, the oral self-care and perceptions of patients attending a dental school clinic in Japan were assessed using a short questionnaire referring to existing oral health models. Methods A cross-sectional study design was used. The study population consisted of sixty-five patients (age range 23-77 with chronic periodontitis. The pre-tested 19-item questionnaire comprised 3 domains; 1 oral hygiene, 2 dietary habits and 3 perception of oral condition. The questionnaire was used as a part of the comprehensive assessment. Results Analyses of the assessment data revealed no major problems with the respondents' perceived oral hygiene habits, although their actual plaque control levels were not entirely adequate. Most of the respondents acknowledged the importance of prevention of dental caries and periodontal diseases, but less than one third of them were regular users of the dental care system. Twenty-five percent of the respondents were considered to be reluctant to change their daily routines, and 29% had doubts about the impact of their own actions on oral health. Analyzing the relationships between patient responses and oral hygiene status, factors like 'frequency of tooth brushing', 'approximal cleaning', 'dental check-up' and 'compliance with self-care advice' showed statistically significant associations (P Conclusion The clinical utilization of the present questionnaire facilitates the inclusion of multiple aspects of patient information, before initiation of periodontal treatment. The significant associations that were found between some of the self-care behaviors and oral hygiene levels document the important role of patient-centered oral health assessment in periodontal care.

    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.

    Introduction Over the years, numerous trials have sufficiently documented benefits of adjuvant administration of antibiotics in combination to Scaling and Root Planing (SRP) in treatment of periodontitis. Nevertheless there are justified doubts in respect to antibiotics administration with regard to increasing development of resistances. Aim The aim of this review study and meta-analysis was to verify a possible benefit of Azithromycin (AZM) as an alternative adjuvant antibiotic in combination with SRP. Materials and Methods Electronic databases (Pubmed) were searched from the earliest point of record until May 2015. A hand search was also conducted. The variables considered in this respect were Probing Depth (PD), Clinical Attachment Level (CAL), Bleeding on Probing (BOP) and SRP. A meta-analysis containing trials comparing SRP as a sole therapy with SRP and administration of AZM was produced once all of the data obtained had been reviewed. Results Six randomised clinical trials were accepted into the review and the meta-analysis following the process of trial selection. Meta-analysis revealed larger overall effects by the systemic administration of AZM compared with SRP on their own in terms of PD, CAL, BOP, Plaque-Index and total bacterial load reduction after three and six months. Conclusion The data used in this study revealed that the systemic administration of AZM is beneficial compared with SRP on its own for the treatment of chronic periodontitis. PMID:27630968

    The aim of this systematic review was to identify and summarize evidence of the association between anthropometric measurements and periodontal status in children and adolescents. We searched PubMed, Institute for Scientific Information Web of Knowledge, Cochrane Library, and 7 additional databases, following the guidance of Preferred Reporting Items for Systematic Reviews and Meta-Analyses, up to December 2014. Observational studies reporting data on the association between anthropometric measurements and periodontal diseases in 2-18-y-old participants were included. An initial search identified 4191 papers; 278 potentially effective studies (k = 0.82) and 16 effective studies (k = 0.83) were included after screening. The mean quality of evidence among the studies was 20.3, according to the Strengthening the Reporting of Observational studies in Epidemiology checklist (k = 0.79). Meta-analyses showed that obesity (measured by body mass index) was significantly associated with visible plaque index (OR: 4.75; 95% CI: 2.42, 9.34), bleeding on probing (OR: 5.41; 95% CI: 2.75, 10.63), subgingival calculus (OR: 3.07; 95% CI: 1.10, 8.62), probing depth (OR: 14.15; 95% CI: 5.10, 39.25) and flow rate of salivary secretion (standardized mean difference: -0.89; 95% CI: -1.18, -0.61). However, various results were reported in the effective studies that were not included in meta-analyses. In conclusion, obesity is associated with some signs of periodontal disease in children and adolescents. Further studies with a comprehensive prospective cohort design and more potential variables are recommended. PMID:26567204

    Full Text Available Literature data have reported that certain Gram-negative anaerobe bacteria from the subgingival environment are important etiological agents of chronic periodontal disease. Based on published criteria identifying periodontal pathogens, major evidences has been shown for: Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis and Tannerella forsythia; moderate evidences for: Prevotella intermedia, Peptostreptococcus /Micromonas/ micros, Fusobacterium nucleatum, Eubacterium nodatum, Campylobacter rectus, and spirochetes (Treponema denticola. Microbiological data has been suggested by several studies as a useful indicator of disease progression, selection of an adjunctive antimicrobial administration, healing assessment and disease recurrence. The results of this study demonstrate statistically significant correlation between periodontal attachment loss and the prevalence of Porphyromonas gingivalis, Tannerella forsythia and Peptostreptococcus (Micromonas micros in deep periodontal pockets of severe chronic periodontitis patients.

    Systematic review of literature was made to assess the extent of accuracy of cone beam computed tomography (CBCT) as a tool for measurement of alveolar bone loss in periodontal defect. A systematic search of PubMed electronic database and a hand search of open access journals (from 2000 to 2015) yielded abstracts that were potentially relevant. The original articles were then retrieved and their references were hand searched for possible missing articles. Only articles that met the selection criteria were included and criticized. The initial screening revealed 47 potentially relevant articles, of which only 14 have met the selection criteria; their CBCT average measurements error ranged from 0.19 mm to 1.27 mm; however, no valid meta-analysis could be made due to the high heterogeneity between the included studies. Under the limitation of the number and strength of the available studies, we concluded that CBCT provides an assessment of alveolar bone loss in periodontal defect with a minimum reported mean measurements error of 0.19 ± 0.11 mm and a maximum reported mean measurements error of 1.27 ± 1.43 mm, and there is no agreement between the studies regarding the direction of the deviation whether over or underestimation. However, we should emphasize that the evidence to this data is not strong. PMID:27563194

    Full Text Available Cigarette smoking is a well-established risk factor for periodontitis and carries an increased risk for loss of periodontal attachment as well as for bone loss. Aims: The purpose of the study was to investigate the pattern of the intraoral distribution of periodontal destruction among cigarette smokers with periodontitis by assessing the periodontal probing depth (PPD and clinical attachment level (CAL. Materials and Methods: Thirty smokers with chronic periodontitis were enrolled in the study. PPD, CAL, plaque index (PI, and bleeding on probing (BOP were measured. The data was pooled for the anterior sextant and the posterior sextant as well as for the facial and lingual surfaces. The degree of periodontal destruction was compared in these sextants. Statistical Analysis: Comparisons were made between maxillary anterior, maxillary posterior, mandibular anterior, and mandibular posterior using the one-way analysis of variance (ANOVA test. When the overall ANOVA showed statistical significance, post hoc testing (Tukey-Kramer multiple comparisons test was performed to explore the differences between any two groups. P -values < 0.05 were considered significant. Results: The maxillary anterior sextant showed significantly higher PPD and CAL loss than the other sextants. Similarly, the maxillary palatal area showed higher probing depth and clinical attachment loss than the facial sites and the mandibular regions. Conclusions: From the results it can be concluded that there is variation in the periodontal tissue destruction in different areas of the oral cavity, with the maximum periodontal destruction in the maxillary palatal region. These observations emphasize the deleterious effects of smoking on the periodontal tissues.

    This study was aimed to provide a longitudinal overview of the subgingival bacterial microbiome using fluorescence in situ hybridization (FISH) technique, in women in the second trimester of pregnancy (between 14 and 24 weeks), and 48 h and 8 weeks postpartum. Of 31 women evaluated during pregnancy, 24 returned for the 48-h and 18 for their 8-week exams postpartum. Probing depth (PD), bleeding on probing, clinical attachment level, and presence of calculus were recorded. Subgingival plaque samples were collected, and FISH was used to identify the numbers of eight periodontal pathogens. Friedman test was used to compare differences between follow-up examinations, followed by a multiple comparison test for a post hoc pairwise comparison. Clinically, a significantly greater number of teeth with PD = 4-5 mm were found during pregnancy than on postpartum examinations. Microbial analysis showed a statistically significant decrease in cell count over the study period for Prevotella nigrescens. P. intermedia, Campylobacter rectus, and Porphyromonas gingivalis also decrease, although not significantly, and Aggregatibacter actinomycetemcomitans increased. No significant changes were found for Fusobacterium nucleatum, Treponema denticola, or Tannerella forsythia. Our data demonstrate a change in the subgingival microbiota during pregnancy, at least for P. nigrescens. PMID:27556678

    2015-01-01

    Full Text Available Context: Systemic conditions, especially chronic infections, have a direct impact on the general health and well-being of an individual. Similarly, the long-standing inflammatory changes seen during periodontitis have been associated with the altered diabetic control, preterm, low birth weight infants, and cardiovascular disease. Being a low-grade infection, the signs may not be as severe as seen in other systemic conditions, but they definitely cannot be ignored. Aims: The present study was designed to compare clinical, hematological, and systemic inflammatory markers in patients with chronic periodontitis. Subjects and Methods: A total of 90 chronic periodontitis patients were selected for the present study from the outpatient department of the Department of Periodontology, and the various clinical and hematological parameters were then assessed. Statistical Analysis Used: Z-test was used to compare the probing depth, clinical attachment loss, hematological parameter, and interleukin-6 values between Group A and Group B. Mann-Whitney U-test was used to compare gingival index, plaque index, and bleeding on probing between Group A and Group B. Results: The results of the study were based on the comparison of the clinical, hematological, and systemic inflammatory markers in smokers and nonsmokers with chronic periodontitis and came out to be statistically highly significant. Conclusions: With the resurgence of emphasis on significance of oral diseases related to systemic health, the medical professionals also need to familiarize themselves with the oral cavity and the oral-systemic inter-relationships to treat or reduce the morbidity of the underlying medical condition. Furthermore, the oral health care professionals must reach out to the medical community and the general public to improve patient care through education and communication about the oral health-systemic health link.

    Full Text Available Background and Objectives: Coenzyme Q 10 is a well studied antioxidant in medical literature, but studies regarding its efficacy in periodontal diseases are few. Hence, the aim of this study was to test the efficacy of coenzyme Q 10 in the form of gel (Perio-Q in patients with chronic gingivitis and periodontitis. Materials and Methods: A total of 12 patients were enrolled. A split mouth design was used for topical (extrasulcular application, intra-pocket application alone, intra-pocket application combined with scaling and root planing (SRP and SRP only in each quadrant, respectively. Clinical parameters such as plaque index, gingival index, gingival bleeding index, probing pocket depth, clinical attachment level were assessed at baseline, 3rd week, and 6th week. The results were subjected to statistical analysis, which were expressed as mean±SD and proportions as percentages. Intra group comparisons were made by paired t-test and one way analysis of variance (ANOVA for inter-group comparisons. Categorical data was analyzed by Fisher′s exact test. Results: The results showed on intra-group analysis significant reduction (P<0.01 of clinical parameters (plaque index (PI, gingival index (GI, gingival bleeding index (GBI, periodontal probing pocket depth (PPD, and clinical attachment level (CAL in all four treatment groups, whereas on inter-group analysis, intra-pocket gel application in combination with SRP showed significant reduction (P<0.05 for PI, GI, GBI, and CAL in comparison to intra-pocket gel alone. Interpretation and Conclusion: In the present study, in chronic periodontitis patients, sub-gingival mechanical debridement only and with Perio-Q gel showed almost similar clinical results without any statistically significant differences. Hence, it confirmed the primary role of basic mechanical approaches in periodontal therapy and did not provide enough clinical support for the superiority of adjunctive use of Perio-Q gel.

Materials and method: A representative group of 58 patients, with ages between 30 and 70 years, were examined, between 2010-2011, as to their periodontal condition, after which peripheric blood was taken over and retinol, α -tocopherol, γ-tocopherol, α-caroten, β-caroten, ß-criptoxantine, zeaxantine, luteine and licopen were extracted from the serum. The values of the antioxidants were measured by high-performance chromatographic liquid technique. Results: The levels of α and β-caroten, β-criptoxantine and zeaxantine were significantly lower in the patients with minimum periodonthopaty debut (p<0.001, as well as in those with increased intensity of periodontopathy debut. β-caroten and β-criptoxantine were the only antioxidants associated with a higher risk of severe periodontic pathologies. Conclusions: The low levels registered for some carotinoides, especially β-caroten and β-criptoxantine, are directly proportional with a higher prevalence of periodonthy installation.

    Aim The aim of the present randomized, double blind, parallel, 2-arm clinical study was to examine the safety and efficacy of frequent applications of chlorhexidine chip (CHX) and flurbiprofen chip (FBP) in patients with chronic periodontitis. Methods Sixty patients were randomized into CHX and FBP groups. Following OHI and scaling and root planing (SRP), baseline pocket depth (PD) measurements, gingival recession and bleeding on probing (BOP) were performed and repeated at week 4 and 8. The assigned chip was placed at weeks 0, 1, 2, 3, 5, 7. Results Mean PD reduction in the CHX group was 2.08 mm (7.17 to 5.09, p < 0.0001). Mean PD reduction in the FBP group was 2.27 mm (6.72 to 4.45, p < 0.0001). Ninety-seven percentage and 95% of these sites exhibited PD reduction ≥1 mm, while 38% and 34% of the sites exhibited PD ≥3 mm (FBP and CHX, respectively). Clinical attachment level gain (1.66 and 1.95 mm, respectively) was statistically significant (p < 0.0001). Baseline BOP dropped from 98% and 100% to 24% and 30% for the CHX and FBP groups, respectively (p < 0.0001). Conclusion Frequent applications of CHX and FBP chips resulted in a significant improvement in the periodontal condition in these sites. Furthermore studies will be required to compare this new treatment regimen to SRP or SRP with single chip application. PMID:22092475

    The aims of this study were to assess the prevalence of periodontal conditions in the Uruguayan adult and elderly population and its association with socioeconomic and behavioral characteristics. Data from adults (35-44, n = 358) and elderly (65-74, n = 411) who participated in the first National Oral Health Survey, Uruguay, 2011, were used. The survey included a household questionnaire addressing socioeconomic characteristics, and tobacco use. Bleeding on probing (BOP), periodontal pockets (CPI) and clinical attachment loss (CAL) were measured by clinical examination. A multivariable analysis was carried out. Considering both age groups, the prevalence of mild/severe periodontal disease was 21.8% and 9.12% for severe periodontal disease. Adjusted analyses revealed an association between high education and all outcomes. Attendance at dental services was negatively associated with BOP and mild to severe periodontitis. Periodontal outcomes were higher in disadvantaged socioeconomic groups. Tobacco consumption has a strong association with periodontal disease in the elderly. PMID:26840821

    Attainment of periodontal regeneration is a significant clinical goal in the management of advanced periodontal defects arising from periodontitis. Over the past 30 years numerous techniques and materials have been introduced and evaluated clinically and have included guided tissue regeneration, bone grafting materials, growth and other biological factors and gene therapy. With the exception of gene therapy, all have undergone evaluation in humans. All of the products have shown efficacy in promoting periodontal regeneration in animal models but the results in humans remain variable and equivocal concerning attaining complete biological regeneration of damaged periodontal structures. In the early 2000s, the concept of tissue engineering was proposed as a new paradigm for periodontal regeneration based on molecular and cell biology. At this time, tissue engineering was a new and emerging field. Now, 14 years later we revisit the concept of tissue engineering for the periodontium and assess how far we have come, where we are currently situated and what needs to be done in the future to make this concept a reality. In this review, we cover some of the precursor products, which led to our current position in periodontal tissue engineering. The basic concepts of tissue engineering with special emphasis on periodontal tissue engineering products is discussed including the use of mesenchymal stem cells in bioscaffolds and the emerging field of cell sheet technology. Finally, we look into the future to consider what CAD/CAM technology and nanotechnology will have to offer. PMID:25900048

    2010-02-01

    Periodontal disease, commonly known as gum disease, affects millions of people. The current method of detecting periodontal pocket depth is painful, invasive, and inaccurate. As an alternative to manual probing, an ultrasonographic periodontal probe is being developed to use ultrasound echo waveforms to measure periodontal pocket depth, which is the main measure of periodontal disease. Wavelet transforms and pattern classification techniques are implemented in artificial intelligence routines that can automatically detect pocket depth. The main pattern classification technique used here, called a binary classification algorithm, compares test objects with only two possible pocket depth measurements at a time and relies on dimensionality reduction for the final determination. This method correctly identifies up to 90% of the ultrasonographic probe measurements within the manual probe's tolerance.

    Periodontitis affects half of the U.S. population over 50, and is the leading cause of tooth loss after 35. It is believed to be caused by growth of complex bacterial biofilms on the tooth surface below the gumline. Photodynamic therapy, a technology used commonly in antitumor applications, has more recently been shown to exhibit antimicrobial efficacy. We have demonstrated eradication of the periopathogens Porphyromonas gingivalis, Fusobacterium nucleatum, and Aggregatibacter actinomycetemcomitans in vitro using PeriowaveTM; a commercial photodisinfection system. In addition, several clinical studies have now demonstrated the efficacy of this treatment. A pilot study in the U.S. showed that 68% of patients treated with PeriowaveTM adjunctively to scaling and root planing (SRP) showed clinical attachment level increase of >1 mm, as opposed to 30% with SRP alone. In a subsequent larger study, a second PeriowaveTM treatment 6 weeks after initial treatment led to pocket depth improvements of >1.5 mm in 89% of patients. Finally, in the most recent multicenter, randomized, examiner-blinded study conducted on 121 subjects in Canada, PeriowaveTM treatment produced highly significant gains in attachment level (0.88 mm vs. 0.57 mm; p=0.003) and pocket depth (0.87 mm vs. 0.63 mm; p=0.01) as compared to SRP alone. In summary, PeriowaveTM demonstrated strong bactericidal activity against known periopathogens, and treatment of periodontitis using this system produced significantly better clinical outcomes than SRP alone. This, along with the absence of any adverse events in patients treated to date demonstrates that PDT is a safe and effective treatment for adult chronic periodontitis.

    The orthodontist is in fact a periodontal-therapist since his aim is to move the teeth with and through the periodontal tissues. It is most important for the orthodontist to be able to determine at the initial clinical examination what are the various periodontal risk factors. When the pathology is obvious with inflammation, periodontal pockets, gingival hyperplasia, edema of the papillae, gingival recessions, the need for periodontal treatment is manifest. But many times, the periodontal evaluation is complicated by the presence of slight variations of the quality of the marginal tissue that represent a risk of developing periodontal defects during the orthodontic treatment. The aim of this presentation is to put forward the importance of the periodontal evaluation during the initial examination of the patient so that, if necessary, an adequate periodontal therapy can be initiated to stabilize the periodontal tissues and thus improves the esthetical outcome.

    Full Text Available Periodontal disease (PD is widely known among veterinarians for its high prevalence and serious consequences to the dogs. The objective of this study was to assess the occurrence of PD in dogs that live in the micro-region of Viçosa, treated at the Veterinary Hospital of the Federal University of Viçosa (HVT - Hospital Veterinário da Universidade Federal de Viçosa, as well as to assess how aware of this disease dog owners are. In order to do so, all dogs treated at the HVT from March 10th, 2009 to November 30th, 2009, on alternate days, had their oral cavities examined. Medical history data, such as age, type of food, main complaint and owner consent, halitosis, presence of dental calculus, inflammation and gingival recession and tooth loss, were collected. A prevalence of 88.67% was found for PD in dogs referred to the HVT, and 2.67% were referred due to this disease. Of all the owners who participated in the study, 43.83% knew about periodontal disease and of these 17.46% made use of some type of prevention or treatment. Therefore, periodontal disease is highly prevalent and the owners are not aware of the disease. Thus, a dog owner clarification program on periodontal disease is needed in the area where HVT-UFV operates.

    Full Text Available Periodontitis is a relatively common disease. Various therapies have been recommended for its treatment which includes nonsurgical, antimicrobial, and surgical therapy. In recent years lasers have been used for all the three above-mentioned purposes. Lasers have been applied for hard and soft tissue debridement, contouring as well as the bacterial load reduction in the pocket. Here we present a case report of chronic periodontitis treated with the help of a new technique, laser-assisted modified Widman flap (LAMWF. The surgical procedure followed with a 980 nm diode laser has been described. The present case report resulted in significant pocket depth reduction, attachment gain, and radiographic evidence of bone fill. The laser-assisted modified Widman flap provided excellent results without complications and high patient as well as clinician satisfaction.

  9. Nonsurgical periodontal treatment.

    Aimetti, Mario

    The primary goal of nonsurgical periodontal therapy is to control microbial periodontal infection by removing bacterial biofilm, calculus, and toxins from periodontally involved root surfaces. A review of the scientific literature indicates that mechanical nonsurgical periodontal treatment predictably reduces the levels of inflammation and probing pocket depths, increases the clinical attachment level and results in an apical shift of the gingival margin. Another parameter to be considered, in spite of the lack of scientific evidence, is the reduction in the degree of tooth mobility, as clinically experienced. It is important to point out that nonsurgical periodontal treatment presents limitations such as the long-term maintainability of deep periodontal pockets, the risk of disease recurrence, and the skill of the operator. A high number of posttreatment residual pockets exhibiting bleeding on probing and > 5 mm deep are related to lower clinical stability. The successful treatment of plaque-induced periodontitis will restore periodontal health, but with reduced periodontium. In such cases, anatomical damage from previous periodontal disease will persist and inverse architecture of soft tissue may impair home plaque removal. The clinician can select one of the following therapeutic options according to the individual patient's needs: - Quadrant/sextant wise instrumentation (conventional staged debridement, CSD). - Instrumentation of all pockets within a 24-hour period with (full mouth disinfection [FMD]) or without (full mouth scaling and root planing [FMSRP]) local antiseptics. Both procedures can be associated with systemic antimicrobials. -CSD or FMD in combination with laser or photodynamic therapy. Patients with aggressive periodontitis constitute a challenge to the clinician. To date there are no established protocols for controlling the disease. However, data from the literature on the application of the FMD protocol combined with amoxicillin

    2015-01-01

    Dental implants have emerged as a first line of treatment to replace missing teeth for both the edentulous and partially dentate patients. The anticipated high degree of success is somewhat challenged by the onset of peri-implantitis. Peri-implant diseases are a cluster of “contemporary” oral infections in humans; they are characterized by the inflammatory destruction of the implant-supporting tissues, as a result of biofilm formation on the implant surface. It is still not clear how the roles of its etiologic agents work. A history of periodontitis, poor oral hygiene, and smoking are considered as risk factors for peri-implant diseases. Occasionally failing implants are associated with iatrogenic factors, that, only recently, have been acknowledged as direct cause of peri-implant complications, i.e.: non-parallel adjacent implants or the presence of a gap, between fixture and prosthetic components. The use both of traditional protocols of nonsurgical periodontal therapy and the diode laser seems to be an effective alternative treatment modality for peri-implantitis. By the application of laser-assisted non-surgical peri-implant therapy the periodontal pocket depth was reduced. Intraoral periapical radiographs, taken at 6 months and 1 year post nonsurgical treatment, seemed to provide evidence of some improvement of the bone level. The present article illustrates the nonsurgical management of one case, where failure to remove residual cement, from an implant-supported dental prosthesis, seemed to cause peri-implant inflammation.

    2011-01-01

    Full Text Available Vaccine is the name applied generally to a substance of the nature of dead or attenuated living infectious material introduced into the body with the object of increasing its power to resist or get rid of a disease. Vaccines are generally prophylactic, i.e. they ameliorate the effects of future infection. One such vaccine considered here is the "Periodontal vaccine". Till date, no preventive modality exists for periodontal disease and treatment rendered is palliative. Thus, availability of periodontal vaccine would not only prevent and modulate periodontal disease, but also enhance the quality of life of people for whom periodontal treatment cannot be easily obtained. The aim of the research should be development of a multispecies vaccine targeting the four prime periodontal pathogens, viz. Porphyromonas gingivalis, T. forsythus, T. denticola and A. comitans. Success is still elusive in case of periodontal vaccine due to the complex etiopathogenesis of the disease.

    This clinical study was to demonstrate the applicability of diffuse reflectance (DR) intensity ratio R620/R575 in the quantification and discrimination of periodontitis and gingivitis from healthy gingiva. DR spectral measurements were carried out with white-light illumination from 70 healthy sites in 30 healthy volunteers, and 63 gingivitis- and 58 periodontitis-infected sites in 60 patients. Clinical parameters such as probing pocket depth, clinical attachment level, and gingival index were recorded in patient population. Diagnostic accuracies for discrimination of gingivitis and periodontitis from healthy gingiva were determined by comparison of spectral signatures with clinical parameters. Divergence of average DR spectral intensity ratio between control and test groups was studied using analysis of variance. The mean DR spectrum on normalization at 620 nm showed marked differences between healthy tissue, gingivitis, and periodontitis. Hemoglobin concentration and apparent SO2 (oxygen saturation) were also calculated for healthy, gingivitis, and periodontitis sites. DR spectral intensities at 545 and 575 nm showed a decreasing trend with progression of disease. Among the various DR intensity ratios studied, the R620/R575 ratio provided a sensitivity of 90% and specificity of 94% for discrimination of healthy tissues from gingivitis and a sensitivity of 91% and specificity of 100% for discrimination of gingivitis from periodontitis.

    Our aim was to investigate the value of salivary concentrations of four major periodontal pathogens and their combination in diagnostics of periodontitis. The Parogene study included 462 dentate subjects (mean age 62.9 ± 9.2 years) with coronary artery disease (CAD) diagnosis who underwent an extensive clinical and radiographic oral examination. Salivary levels of four major periodontal bacteria were measured by quantitative real-time PCR (qPCR). Median salivary concentrations of Porphyromonas gingivalis, Tannerella forsythia, and Prevotella intermedia, as well as the sum of the concentrations of the four bacteria, were higher in subjects with moderate to severe periodontitis compared to subjects with no to mild periodontitis. Median salivary Aggregatibacter actinomycetemcomitans concentrations did not differ significantly between the subjects with no to mild periodontitis and subjects with moderate to severe periodontitis. In logistic regression analysis adjusted for age, gender, diabetes, and the number of teeth and implants, high salivary concentrations of P. gingivalis, T. forsythia, and P. intermedia were significantly associated with moderate to severe periodontitis. When looking at different clinical and radiographic parameters of periodontitis, high concentrations of P. gingivalis and T. forsythia were significantly associated with the number of 4-5 mm periodontal pockets, ≥6 mm pockets, and alveolar bone loss (ABL). High level of T. forsythia was associated also with bleeding on probing (BOP). The combination of the four bacteria, i.e., the bacterial burden index, was associated with moderate to severe periodontitis with an odds ratio (OR) of 2.40 (95% CI 1.39-4.13). When A. actinomycetemcomitans was excluded from the combination of the bacteria, the OR was improved to 2.61 (95% CI 1.51-4.52). The highest OR 3.59 (95% CI 1.94-6.63) was achieved when P. intermedia was further excluded from the combination and only the levels of P. gingivalis and T

In logistic regression analysis adjusted for age, gender, diabetes, and the number of teeth and implants, high salivary concentrations of P. gingivalis, T. forsythia, and P. intermedia were significantly associated with moderate to severe periodontitis. When looking at different clinical and radiographic parameters of periodontitis, high concentrations of P. gingivalis and T. forsythia were significantly associated with the number of 4-5 mm periodontal pockets, ≥ 6 mm pockets, and alveolar bone loss (ABL. High level of T. forsythia was associated also with bleeding on probing (BOP. The combination of the four bacteria, i.e. the bacterial burden index, was associated with moderate to severe periodontitis with an odds ratio (OR of 2.40 (95% CI 1.39–4.13. When A. actinomycetemcomitans was excluded from the combination of the bacteria, the OR was improved to 2.61 (95% CI 1.51–4.52. The highest odds ratio 3.59 (95% CI 1.94–6.63 was achieved when P. intermedia was further excluded from the combination and only the levels of P. gingivalis and T. forsythia were used. Salivary

    This study was performed to compare the inverted digital images and film-based images of dry pig mandibles to measure the periodontal bone defect depth. Forty 2-wall bone defects were made in the proximal region of the premolar in the dry pig mandibles. The digital and conventional radiographs were taken using a Schick sensor and Kodak F-speed intraoral film. Image manipulation (inversion) was performed using Adobe Photoshop 7.0 software. Four trained examiners made all of the radiographic measurements in millimeters a total of three times from the cementoenamel junction to the most apical extension of the bone loss with both types of images: inverted digital and film. The measurements were also made in dry mandibles using a periodontal probe and digital caliper. The Student's t-test was used to compare the depth measurements obtained from the two types of images and direct visual measurement in the dry mandibles. A significance level of 0.05 for a 95% confidence interval was used for each comparison. There was a significant difference between depth measurements in the inverted digital images and direct visual measurements (p>|t|=0.0039), with means of 6.29 mm (IC{sub 95%}:6.04-6.54) and 6.79 mm (IC{sub 95%}:6.45-7.11), respectively. There was a non-significant difference between the film-based radiographs and direct visual measurements (p>|t|=0.4950), with means of 6.64 mm(IC{sub 95%}:6.40-6.89) and 6.79 mm(IC{sub 95%}:6.45-7.11), respectively. The periodontal bone defect measurements in the inverted digital images were inferior to film-based radiographs, underestimating the amount of bone loss.

    2016-01-01

    Aim This 12-week prospective, randomized, double-blind, two-center trial evaluated the impact of a microcrystalline zinc hydroxyapatite (mHA) dentifrice on plaque formation rate (PFR) in chronic periodontitis patients. We hypothesized that mHA precipitates cause delayed plaque development when compared to a fluoridated control (AmF/SnF2), and therefore would improve periodontal health. Material & Methods At baseline and after 4 and 12 weeks, PFR and other clinical and microbiological parameters were recorded. Seventy periodontitis patients received a mHA or AmF/SnF2 dentifrice as daily oral care without hygiene instructions. Four weeks after baseline, participants received full mouth debridement and continued using the dentifrices for another 8 weeks. Results Primary outcome PFR did not change statistically significantly from baseline to weeks 4 and 12, neither in mHA (n = 33; 51.7±17.2% vs. 48.5±16.65% vs. 48.4±19.9%) nor in AmF/SnF2-group (n = 34; 52.3±17.5% vs. 52.5±21.3% vs. 46.1±21.8%). Secondary clinical parameters such as plaque control record, gingival index, bleeding on probing, and pocket probing depth improved, but between-group differences were not statistically significant. Microbiological analyses showed similar slight decreases in colony-forming units in both groups. Conclusion In patients with mild-to-moderate periodontitis, periodontal therapy and use of a mHA-or AmF/SnF2 dentifrice without instructions induced comparable improvements in periodontal health but did not significantly reduce the PFR.

    Full Text Available Objective Salivary mucin and amylase levels are increased in patients with chronic periodontitis (CP. Due to the fact that aggressive periodontitis (AgP not only differs from chronic periodontitis in terms of its clinical manifestation, the aim of this study was to compare salivary mucin and amylase levels and their relation to the clinical parameters of patients with aggressive periodontitis with that of patients with chronic periodontitis. Material and Methods Eighty subjects were divided into two groups: 20 patients with AgP and their 20 matched controls and 20 patients with CP and their 20 matched controls, based on clinical attachment loss (CAL, probing pocket depth (PPD and bleeding on probing (BOP. Whole unstimulated saliva was obtained and mucin, amylase and protein were determined by colorimetric methods. Pearson's correlation analysis was used to determine the relationship between salivary mucin, amylase and protein levels and the clinical parameters. Results Salivary mucin, amylase and protein levels were increased in patients with AgP and CP but there were no differences between them or between control groups. Pearson's correlation analysis, determined in the entire subjects studied, showed a positive and significant correlation of mucin, amylase and proteins with CAL and PPD and a negative correlation with the flow rate. When Pearson's correlation analysis was carried out in each group separately, Fisher's z transformation showed no significant difference between both groups. Conclusion Comparison of the salivary levels of mucin, amylase and protein and their relationship with clinical parameters of AgP patients with that of CP patients revealed no differences between both groups.

    Data are presented from a multi-center, prospective, longitudinal, clinical trial comparing four different treatments for periodontitis, (1) the LANAPTM protocol utilizing a FR pulsed-Nd:YAG laser; (2) flap surgery using the Modified Widman technique (MWF); (3) traditional scaling and root planing (SRP); and (4) coronal debridement (CD). Each treatment was randomized to a different quadrant. Fifty-one (54) subjects were recruited at five centers that included both private practice and university-based investigators. At 6-months and 12 months post-treatment the LANAPTM protocol and MWF yielded equivalent results based on changes in probing depths. The major difference observed between the two procedures was that patients reported significantly greater comfort following the LANAP™ procedure than following the MWF (Poral) effect on sub-gingival wound healing.

    Periodontal health states are difficult to quantify and no formal scale quantifying patients' utilities for periodontal health states exits. Multi-attribute utility (MAU) techniques were used to develop such a scale. The MAU scale may be used to quantify patients' assessment of their current periodontal health and that of possible treatment outcomes. Such data, combined with probability values in formal decision analysis techniques would result in improved rationality of treatment planning for periodontal disease. 20 patients attending for routine undergraduate care were interviewed. Data from these interviews were sorted into groups of common interest (domains). Intra-domain health statements were complied from the interview content. 21 patients ranked the intra-domain statements on a scale of 0-100. This same group of patients also performed an inter-domain weighting. Mean results showed that patients were 2X as concerned with how they felt and with the prognosis of possible outcomes, than with how they looked and what facts they knew about their oral health. However, the real value of utilities research lies in application of individual results to treatment planning as there is a wide range of opinion regarding outcome health states. PMID:8891929

    Full Text Available Chronic periodontitis is a result of polymicrobial infection and its treatment aims removal of dental calculus and biofi lm from the periodontal pocket. Many hand and power-driven instruments are created for this purpose. In recent years, lasers are widely discussed tools for periodontal therapy. The aim of the present study is to evaluate the early microbiological and clinical effectiveness of the Er:YAG laser in the treatment of chronic periodontitis. 30 patients with moderate chronic periodontitis were enrolled in the study. Using a split-mouth design they were treated either with Er:YAG laser (chisel tip, 100 mJ, 15 Hz, 5-6 water spray-test group or with Gracey curettes- control group. Probing pocket depth (PPD, gingival recession (GR, clinical attachment level (CAL, bleeding on probing and plaque presence were evaluated at baseline and one month after the therapy. Microbiological samples were taken from the deepest four pockets of each quadrant from 20 randomly selected patients (n = 80. They were evaluated using real time PCR for periodontal pathogens from the red complex (Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia. One month after therapy in the control group PPD decreased from 4.59 mm to 3.36 mm, the CAL gain was 1.09 mm and the reduction of bleeding and plaque - from 87.9% to 33.7% and from 75.9% to 40.9%, respectively. In the test group PPD decreased from 4.58 mm to 3.15 mm, the CAL gain was 1.37mm and the reduction of bleeding and plaque was from 85.6% to 25.9% one month after the treatment. The results were statistically significant in favour of the laser group (p < 0.05. Microbiological analysis revealed that the pathogens from the red complex decreased 3 times in the control and 6 times in the test group. Therefore, the Er:YAG laser demonstrate pronounced early effectiveness in chronic periodontitis treatment and would be appropriate alternative of the conventional periodontal therapy.

    Full Text Available The association between diabetes mellitus and chronic periodontal disease has long been established. Most of the researches linking these two very common chronic diseases were based on type 2 diabetes mellitus and chronic periodontal disease. However, this study was conducted to investigate the association between type 1 diabetes and chronic periodontal disease in Malaysian subjects. Forty-one Malaysian subjects, of which 20 subjects were type 1 diabetics and with chronic periodontal disease (test group and 21 subjects with only chronic periodontal disease (control group, were included in the study. Periodontal parameters and plaque samples for microbiological evaluation were done at baseline, 2 and 3 months after nonsurgical periodontal therapy. Blood samples were taken from only the test group and evaluated for HbA1c at baseline and 3 months after periodontal therapy. There were no statistically significant difference in periodontal parameters between groups (P>0.05 and no significant improvement in the level of HbA1c in the test group. Microbiological studies indicated that there were significant reductions in the levels of the tested pathogens in both groups. The results of our study were similar to the findings of several other studies that had been done previously.

  11. Periodontal Probe Improves Exams, Alleviates Pain

    2008-01-01

    Dentists, comedian Bill Cosby memorably mused, tell you not to pick your teeth with any sharp metal object. Then you sit in their chair, and the first thing they grab is an iron hook!" Conventional periodontal probing is indeed invasive, uncomfortable for the patient, and the results can vary greatly between dentists and even for repeated measurements by the same dentist. It is a necessary procedure, though, as periodontal disease is the most common dental disease, involving the loss of teeth by the gradual destruction of ligaments that hold teeth in their sockets in the jawbone. The disease usually results from an increased concentration of bacteria in the pocket, or sulcus, between the gums and teeth. These bacteria produce acids and other byproducts, which enlarge the sulcus by eroding the gums and the periodontal ligaments. The sulcus normally has a depth of 1 to 2 millimeters, but in patients with early stages of periodontal disease, it has a depth of 3 to 5 millimeters. By measuring the depth of the sulcus, periodontists can have a good assessment of the disease s progress. Presently, there are no reliable clinical indicators of periodontal disease activity, and the best available diagnostic aid, periodontal probing, can only measure what has already been lost. A method for detecting small increments of periodontal ligament breakdown would permit earlier diagnosis and intervention with less costly and time-consuming therapy, while overcoming the problems associated with conventional probing. The painful, conventional method for probing may be destined for the archives of dental history, thanks to the development of ultrasound probing technologies. The roots of ultrasound probes are in an ultrasound-based time-of-flight technique routinely used to measure material thickness and length in the Nondestructive Evaluation Sciences Laboratory at Langley Research Center. The primary applications of that technology have been for corrosion detection and bolt tension

    Introduction: Periodontitis is a chronic inflammatory disease due to exposition to plaque and tartar. Conventional treatments consist of scaling and root planing (SRP) and antibiotics administration. Among them encouraging results have been obtained using alternative protocols, like the antimicrobial photodynamic therapy (PDT). Aim of the Study: Evaluation of PDT effects added to conventional methods. Materials and Methods: 11 patients (4M/7F, 37-67 years aged, non-smoking) affected by untreated chronic periodontal disease, with >3mm pockets in at least 4 teeth were divided in two groups, test and control group. Each patient had to made full-intraoral before and after the treatment. The test group received SRP+PDT, while the control group was subjected to SRP. The PDT was performed through the HELBO®TheraLite (Bredent Medical), diode laser battery powered 670nm with an output of 75mW/cm2. The Helbo Blue photosensitizer, containing methylene blue, was used. The exposure time to the laser effect was of 10'' for each site, for a total of 60'' at 3J/cm2. Results: Both groups had a significant improvement in the reduction of pocket depth (PD), above all in the test group. Statistical analysis was performed through the T-test, evaluating PD between the two groups p=0.96 (p> 0.05), resulting not statistically significant. Conclusion: PDT is a promising support to SRP, achieving a significant reduction in the pocket depth, but more cases are needed to confirm the validity of the used protocol.

    Full Text Available Problem statement: Smoking plays a significant role in the development of periodontal disease. Quantitative relation between smoking and increased severity of periodontal disease, by means of biochemical marker has not been described in Malaysian population. The present study was designed to apply serum cotinine measurement as a quantitative method to evaluate smoking levels in Malaysian patients and to correlate these levels with the severity of periodontal disease. Approach: The study group consisted of 80 healthy individuals (20-64 year, Current Smokers 26, Non Smokers 27 and Former Smokers 27. The subjects were then asked to complete a questionnaire including the demographic, socioeconomic status, medical history and history of cigarette smoking. The periodontal variables recorded were amount of Visible Plaque score, gingival bleeding Index and community periodontal index. Samples of blood “10 mL” were obtained in vacutainer tubes containing EDTA for quantitative analysis of serum levels of cotinine. The serum samples were analyzed for cotinine content by means of a competitive-inhibition ELISA technique. Results: Current smokers represent the highest mean cotinine serum level, 95.5 ng mL-1, compared to former smokers, 35.5 ng mL-1 and non smokers, 22.9 ng mL-1. The mean serum cotinine level in periodontally healthy patient showed the highest cotinine level (84 ng mL-1 followed by the gingivitis patients (68 ng mL-1 and (50 ng mL-1 for periodontitis patients. Conclusion: The present observations clearly indicate an association between smoking, periodontal disease clinical parameters “plaque, gingival bleeding scores” and cotinine serum levels in current smokers. Cotinine serum levels doesn’t affected by the existence or the severity of periodontal disease.

    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.

    Full Text Available Background: Oral exfoliative cytology includes the study and interpretation of the features cells exfoliated from the oral mucosa. The aim of this study was to analyze cytological changes in the periodontal pocket of patients with different clinical stages of aggressive periodontitis (AP and chronic periodontitis (CP. Materials and Methods: Patients aged 24-54 years, of whom 41 were diagnosed with AP, 40 with CP, sub-classified as mild, moderate and severe periodontitis, and 40 healthy individuals who were the control group. Samples of the epithelium of the periodontal pocket were taken for the cytological study. Results: Superficial and intermediate cell values were significantly greater in patients with AP than in patients with CP or the control group. Histiocyte number was higher in patients with CP than in those with AP, and differed significantly in both types of periodontitis compared to the control group. There were significant differences in polymorphonuclear neutrophil leukocytes when both types of periodontitis were compared to the control group. Microbial flora was statistically higher in patients with CP, and there were differences between patients with periodontitis and the control group. Conclusions: The cytological study demonstrated that patients with AP had greater tissue damage, shown by the increase in intermediate and superficial cells of the epithelium of the periodontal pocket compared to the group of healthy subjects and to a lesser extent, to patients with CP. Only superficial cells made it possible to differentiate the sub-stages of the disease.

    Objective: To detect the infection frequencies of different genotypes of Epstein-Barr virus (EBV) in subgingival samples from chronic periodontitis (CP) patients, and to discuss the correlation between infection with EBV and clinical parameters. Methods: Nested-PCR assay was used to detect EBV-1 and EBV-2 in subgingival samples from 65 CP patients, 65ivitis patients and 24 periodontally healthy individuals. The amplicons were further identified by restriction fragment length polymorphism analysis (RFLP) with endonucleases Afa I and Stu I. Clinical parameters mainly included bleeding on probing riodontally healthy individuals, the infection frequencies were 47.7% , 24.6% and 16.7% for EBV-1, and 15.4% , 7.7% and 0% for EBV-2,ectively. In 2 out of the 65 CP patients co-infection of EBV-1 and EBV-2 was found. The positive rate of EBV-1 in chronic periodontitis patients was higher than that in gingivitis patients (P=0.01) and periodontally healthy individuals (P=-0.01). But no .05) or in EBV-2frequency among the three groups (P>0.05). In CP patients, higher mean BOP value was found in EBV-1 or EBV-2 positive egative ones (P<0.01), but with no statistical difference in the mean PD or AL value between EBV positive and negative patients (P>0.05). After initial periodontal treatment, 12 out of the 21 EBV-1 positive CP patients did not s a sensitive, specific and stable method to detect EBV-1 and EBV-2 in subgingival samples. Subgingival infection with EBV-1 is closely associated with chronic correlated with BOP.

    Full Text Available Aim: Find the periodontal treatment that best maintained clinical results over time evaluated by changes in pocket depth (PD and clinical attachment level (CAL. Methods: 229 patients with chronic periodontitis from USA (n=134 and Sweden (n=95 were randomly assigned to eight groups receiving 1 scaling+root planing (SRP alone or combined with 2 surgery (SURG+systemic amoxicillin (AMOX+systemic metronidazole (MET; 3 SURG+local tetracycline (TET; 4 SURG; 5 AMOX+MET+TET; 6 AMOX+MET; 7 TET; and 8 SURG+AMOX+MET+TET. Antibiotics were given immediately after SRP. Plaque, gingival redness, bleeding on probing, suppuration, PD, and CAL were recorded at baseline and after 3, 6, 12, 18, and 24 months. Treatment effects were evaluated by linear multilevel regression and logistic multilevel regression models. We considered only data from sites with a baseline PD of at least 5 mm of 187 patients completing the study. Results: Surgically treated patients experienced most CAL loss. Adjunctive therapy including SURG was most effective in reducing PD. Combining SURG with AMOX, MET, and TET gave significant clinical benefits. Past and current smoking habits were significant predictors of deeper PD. Only current smoking was a significant predictor of CAL loss. Bleeding, accumulation of plaque, gingival redness, and suppuration were significant predictors of further CAL loss and deeper PD. Conclusions: Both surgical and non-surgical therapies can be used to arrest chronic periodontitis. SURG+AMOX+MET+TET gave best maintenance of clinical results.

    Peri-implant diseases present in two forms: peri-implant mucositis and peri-implantitis. The prevalence of peri-implant complications is significantly rising. The aim of this study was to compare conventional treatment of inflamed peri-implant tissues with conventional treatment together with diode laser application. Twenty-seven patients (age 36 to 67, 15 women and 12 men, 12 smokers and 15 non-smokers) requiring treatment for mucositis or peri-implantitis were taken into account for this preliminary study. Plaque index (PI), pocket depth (PD), and bleeding on probing (BoP) were recorded at baseline evaluation. Patients in control group (CG) received conventional non-surgical periodontal treatment. Patients in test group received conventional non-surgical periodontal treatment together with diode laser application (810 nm, 30 s, 1 W, 50 Hz, t on = 100 ms, t off = 100 ms, energy density = 24.87 J/cm(2)). Paired t test was used to evaluate the difference in repeated measurements of considered indexes at T 0 and T 1 (1 year) in both groups. A total of 606 sites were taken into account in the test group (TG) and 144 in the CG. PD mean variation in the TG was 2.66 mm ± 1.07, while mean PD variation in the CG was 0.94 ± 1.13 mm. Paired t testing of the variation in PD in CG and TG revealed a statistically significant difference between the two groups (p diode laser seems to be an additional valuable tool for peri-implant disease treatment.

    Full Text Available Late implant failures, caused by the inflammation of surrounding tissues are a problem in implant dentistry. The path of bacterial transmission from teeth to implants is not completely understood. Therefore, the purpose of this study was to analyze intraindividual bacterial transmission characterizing subgingival microbiomes in teeth and implants, both in healthy subjects and in those with signs of periodontitis or peri-implantitis. Samples of peri-implant and dental sulcus fluid were collected. To identify the predominant microbiota, amplified fragments of bacterial 16S rRNA gene were separated by single strand conformation polymorphism analysis, sequenced and taxonomically classified. A total of 25 different predominant genera were found in the diseased group and 14 genera in the healthy group. Species richness did not differ significantly between implants, neighboring teeth and teeth with largest probing depth in the diseased group. Additionally, no differences between teeth and implants in the healthy group were detected. In contrast, microbial diversity varied between the different sampling points. Species richness is similar in healthy and diseased sites, but the composition of the bacterial community differed within the individual subjects. The underlying analyses strongly suggest that complete transmission from neighboring teeth to implants is unlikely.

    Objective: To find out the effect of periodontal treatment on orthodontic treatment. Methods: A total of 30 cases from January 2013 to November 2014 were taken into the research. The periodontal health indicators (probing depth/PD, tooth mobility/TM, bleeding on probing/BOP, and clinic attachment loss/CAL) were taken into measurements, before any treatment T0, after 3-month periodontal treatment T1 and after the periodontal treatment combined with orthodontic treatment T2, respectively. Also, the changes of the distance from alveolar ridge crest to cement-enamel junction (CEJ), root length and density of alveolar bone were observed through CBCT measurement. Results: The TM in T1 was obviously less than that in T0 (P0.05). The root length in T2 and T1 shared no statistic difference and the root resorption did not occur after the orthodontic treatment (P>0.05). The distance from alveolar ridge crest to CEJ did not result in alveolar resorption after orthodontic treatment (P>0.05). The changes of density of alveolar bone in T1 were better than that in T0 while after the orthodontic treatment, it decreased. Conclusions: The periodontal treatment before orthodontic treatment plays an efficient role in controlling the periodontal disease and meanwhile, creates a good condition for further orthodontic treatment to restore both good appearance and masticatory function of teeth.

    Full Text Available There are many studies that evaluate possible risk factors for periodontal diseases in animals. Most of them have focused only on the biological aspects of disease occurrence; therefore, it has been difficult to compare studies of the different methodological approaches. The aim of the present study was to compare different methods - linear and area - of the evaluation of morphometrical alveolar bone loss. Sixty hemimaxillae, defleshed and stained with 1% methylene blue to delineate the cementoenamel junction and alveolar bone crest, were obtained from a previous study that induced periodontal disease by means of ligatures in two groups of fifteen Wistar rats during 9 weeks. Ligatures were placed around the right upper second molars, and the contra-lateral teeth remained as intra-group controls. Digital photographs were taken from the specimens and submitted to a single, calibrated, blind examiner who performed the morphometrical evaluation of alveolar bone loss using both linear and area methods. Mean values of linear and area measurements were obtained from each side - buccal and palatal - of the specimens. The degree of association between the two methods was determined by Pearson's Correlation Coefficient. An almost perfect association (0.98 was determined between the linear and area evaluations. A mathematical formula was subsequently created to estimate the total area of alveolar bone loss, from linear mean measurements. Both methods were suitable for detecting bone level alterations. The results of the present study allow for the transformation of data and better compilation of results from different studies.

    The results of recent published studies focusing on the effect of azithromycin as an adjunct to scaling and root planing (SRP) in the treatment of chronic periodontitis are inconsistent. We conducted a meta-analysis of randomized controlled clinical trials to examine the effect of azithromycin combined with SRP on periodontal clinical parameters as compared to SRP alone. An electronic search was carried out on Pubmed, Embase and the Cochrane Central Register of Controlled Trials from their earliest records through December 28, 2014 to identify studies that met pre-stated inclusion criteria. Reference lists of retrieved articles were also reviewed. Data were extracted independently by two authors. Either a fixed- or random-effects model was used to calculate the overall effect sizes of azithromycin on probing depth, attachment level (AL) and bleeding on probing (BOP). Heterogeneity was evaluated using the Q test and I(2) statistic. Publication bias was evaluated by Begg's test and Egger's test. A total of 14 trials were included in the meta-analysis. Compared with SRP alone, locally delivered azithromycin plus SRP statistically significantly reduced probing depth by 0.99 mm (95% CI 0.42-1.57) and increased AL by 1.12 mm (95% CI 0.31-1.92). In addition, systemically administered azithromycin plus SRP statistically significantly reduced probing depth by 0.21 mm (95% CI 0.12-0.29), BOP by 4.50% (95% CI 1.45-7.56) and increased AL by 0.23 mm (95% CI 0.07-0.39). Sensitivity analysis yielded similar results. No evidence of publication bias was observed. The additional benefit of systemic azithromycin was shown at the initially deep probing depth sites, but not at shallow or moderate sites. The overall effect sizes of systemic azithromycin showed a tendency to decrease with time, and meta-regression analysis suggested a negative relation between the length of follow-up and net change in probing depth (r = -0.05, p = 0.02). This meta-analysis provides further

    Periodontal disease is a localised inflammatory response caused by the infection of a periodontal pocket arising from the accumulation of subgingival plaque. Periodontal disease has been considered as a possible risk factor for other systemic diseases such as cardiovascular diseases and pre-term low birth weight infants. Advances in understanding the aetiology, epidemiology and microbiology of periodontal pocket flora have revolutionised the therapeutic strategies for the management of periodontal disease progression. This review summarises the recent developments in the field of intra-pocket drug delivery systems and identifies areas where further research may lead to a clinically effective intra-pocket delivery system.

    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 BACKGROUND: Although periodontitis is a risk factor for cardiovascular disease (CVD, the influence of periodontitis on Marfan syndrome (MFS with CVD is unclear. The aim of this study was to assess the relationship between periodontal bacterial burden and MSF with CVD. METHODS AND RESULTS: The subjects were patients with MFS with CVD (n = 47; age and gender matched non-MFS CVD patients (n = 48 were employed as controls. Full-mouth clinical measurements, including number of teeth, probing of pocket depth (PD, bleeding on probing (BOP and community periodontal index (CPI were recorded. We also evaluated the existence of three periodontal pathogens, Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, and Prevotella intermedia using polymerase chain reaction assays. Serum antibody titers against the pathogens were also measured. We revealed that MFS with CVD patients had periodontitis more frequently than the age and gender matched non-MFS CVD control subjects. MFS with CVD patients had significantly severer periodontitis, fewer remaining teeth and deeper PD compared to the non-MFS CVD controls. Furthermore, the serum antibody titer level against Prevotella intermedia was significantly lower in MFS plus CVD patients compared to the non-MFS CVD patients. CONCLUSION: Periodontitis may influence the pathophysiology of cardiovascular complications in MFS patients. A specific periodontal pathogen might be a crucial therapeutic target to prevent CVD development.

    Full Text Available Objective: Periodontal diseases are common in the society and some researchers suggested an association between rheumatoid arthritis (RA and periodontal diseases. The present study was carried out to evaluate the so-called association in Iranian adults.Materials and Methods: In this case-control study, the samples were recruited from patients referred to Loghman Hospital, Tehran, during 2004-2005. Fifty patients with RA aging 27-50 with no other systemic diseases were matched for sex, age, smoking, and oral hygiene status with healthy control samples. The drugs affecting periodontium status were excluded from the study. Clinical attachment loss (CAL index was measured by a scaled Williams periodontal probe in both groups at four surfaces, and the type of periodontitis was determined. Chi-square, Mann-Whitney U, and t-student tests served for statistical analyses.Results: In RA group, 30 patients (60% had moderate to severe periodontitis while in control group the condition was detected among eight patients (16%. Significant difference existed between the two groups in terms of periodontitis stage (P<0.001. Median ofthe CAL scores was 4.5 mm and 0 mm in RA and control patients, respectively, with significant difference (P<0.001.Conclusion: The results suggest higher potentiality for moderate to severe periodontitis involvement among RA patients, possibly due to similar nature of the two diseases. Periodontal assessment of RA patients is necessary for early diagnosis and consequent treatment.

    Periodontal infections can act as focus of infection, aggravating the immunocompromised state of End Stage Renal Disease patients (ESRD). Aim: Evaluation of the periodontal health status of ESRD patients undergoing haemodialysis and establishing the underlying association between renal failure and periodontal disease. Material and Methods: Eighty control and test subjects were included in the study, after matching age and sex. Creatinine and GFR were measured in each patient. Oral hygiene index- Simplified (OHI-S), Gingival Index (GI), Pocket Depth (PD) and Clinical Attachment Level (CAL) were recorded as periodontal parameters to assess the correlation between the subjects of the two groups. Further, the test group was divided into three sub–groups, on basis of duration, as less than 6 months, from 6 months to one year and more than one year. Statistical Analysis: Student’s t – test and ANOVA were used to analyze the inter–group and intragroup comparisons. Results: Statistical significant difference was observed for all periodontal parameters between the test and control group. However, difference amongst periodontal parameters on basis of duration of haemodialysis was seen between the subgroups of test subjects, it was not found to be statistically significant. Conclusion: Severity of periodontal diseases in ESRD patients undergoing haemodialysis majorly affected due to debilitating condition of the subjects. Dialysis vintage has only a small role to play in worsening of the condition. Further research is needed to potentiate the establishment of two–way relationship between renal disease and periodontal condition. PMID:24298526

Specific measures for periodontitis included probing pocket depth (PDD, clinical attachment level (CAL. Bleeding score (BI and plaque score (PI were also assessed and compared in the two groups.Results: No significant association was found between different paraclinical findings (including CRP, RF, ESR and age of the onset of RA. The highest level of IL-17 was found in RA patients with moderate to severe periodontitis ( p =0.013. The prevalence and severity of periodontitis were higher in the test group. In the present study, Kruskal-Wallis test was used for evaluation of serum level of IL-17.Conclusion: The findings of the present study suggest that rheumatoid arthritis patients are prone to severe periodontitis and the level of IL-17 in the serum is positively associated with severity of periodontitis.

  17. The Effects of Cigarette Smoke Condensate and Nicotine on Periodontal Tissue in a Periodontitis Model Mouse.

    Directory of Open Access Journals (Sweden)

    Mikiko Kubota

    Full Text Available Cigarette smoking is a major lifestyle-related risk factor for periodontal diseases. However, the pathophysiological role of cigarette smoking in periodontal disease has yet to be fully elucidated. Here we report that the systemic administration of cigarette smoke condensate or nicotine, which is the major ingredient of cigarette smoke, augmented alveolar bone loss. Concomitantly, the number of osteoclasts in periodontal tissues increased and the expression of receptor activator of nuclear factor κB ligand was upregulated at the ligated side in mice with periodontitis. Nicotine also attenuated alveolar bone repair after ligature removal. These observations highlight the destruction of periodontal tissue by smoking and the unfavorable clinical course of periodontal disease in patients with a cigarette smoking habit. The present study demonstrates that periodontal disease models are useful for elucidating the pathogenesis of cigarette smoking-related periodontal diseases.

    2016-06-01

    There remains a high prevalence of mild-to-moderate forms of periodontal diseases in both developed and developing countries. Although many periodontal specialty practices currently place strong emphasis on implant surgery, periodontal plastic surgery and esthetics, general dentists and hygienists have often assumed more responsibility than periodontal specialty practices for the diagnosis, treatment, assessment and maintenance, and possible referral, of their patients. To address these current trends and challenges, this volume of Periodontology 2000 presents a series of topics on the basic biological principles of periodontal disease, as well as on approaches to diagnosis, treatment planning and treatment, in what is called 'conservative' or 'noninvasive' periodontal therapy. These topics include risk assessment of the periodontal condition; reduction, elimination and/or control of etiologies and risk factors, including mechanical, antimicrobial and host-modulation approaches; considerations for evaluation of clinical outcomes based on treatment approaches; and selected topics in laser therapy, halitosis and gingival recession.

    Chronic periodontitis is a serious infectious and inflammatory oral disease of humans worldwide. Conventional treatment modalities are effective for controlling periodontal disease. However, the regeneration of damaged periodontal tissues remains a major challenge in clinical practice due to the complex structure of the periodontium. Stem cell-based regenerative approaches combined with the usage of emerging biomaterials are entering a new era in periodontal regeneration. The present review updates the current knowledge of periodontal ligament stem cell-based approaches for periodontal regeneration, and elaborates on the potentials for clinical application.

    Full Text Available Background: Recently, there has been interest in non-mammalian collagen sources such as fish collagen in periodontal regeneration. In the present study, collagen barrier membrane of fish origin was assessed in the treatment of periodontal intrabony defects. Materials and Methods: Ten systemically healthy chronic periodontitis patients having a paired osseous defect in the mandibular posterior teeth were selected and randomly assigned to receive a collagen membrane (test or open flap debridement (control in a split mouth design. Clinical parameters such as Plaque index, Gingival bleeding index, Probing pocket depth, Relative attachment level, and Recession were recorded at baseline, 3, 6, and at 9 months, while radiographic evaluation was done to assess alveolar crestal bone level and percentage of defect fill at 6 and 9 months using autoCAD 2007 software. Student′s t test (two-tailed, dependent was used to find the significance of study parameters on continuous scale. Significance was set at 5% level of significance. Wilcoxon signed rank test was used to find the significance of percentage change of defect fill. Results: The comparison between the two groups did not show any statistically significant differences in the parameters assessed (P > 0.05 but, within each group, clinical parameters showed statistically significant differences from baseline to 9 months (P < 0.05. Conclusion: Within the limits of the study, it can be inferred that no significant differences were found either by using collagen membrane of fish origin or open flap debridement in the treatment of periodontal intrabony defects.

    The aim of this study was to assess the effects of the antimicrobial photodynamic laser therapy performed during the treatment of deep periodontal disease by using 40 MHz high frequency ultrasonography. The periodontal data recorded during the clinical examination before each treatment session were compared with volumetric changes of the gingiva measured on periodontal ultrasound images. The results show a significant decrease of gingival tissue inflammation proved both by a significant decrease of bleeding on probing as well as by a decrease of the gingival tissues volume on sites where the laser therapy was performed. Periodontal tissues that benefit of laser therapy besides classical non-surgical treatment showed a significant clinical improvement of periodontal status. Based on these findings we were able to conclude that the antimicrobial photodynamic laser therapy applied on marginal periodontium has important anti-inflamatory effect. The periodontal ultrasonography is a method which can provide useful data for assessing the volume changes of gingival tissues, allowing a precise monitoring of marginal periodontitis.

PD was performed at 6 sites: mesial-buccal (MB, central-buccal (CB, distal-buccal (DB, mesial-lingual (ML, central-lingual (CL and distal-lingual (DL. Data from all teeth present were included when, at least, one site with CAL ³ 4mm was observed. After statistical analysis (Friedman and Kruskal-Wallis ANOVA tests CB and CL sites showed CAL values statistically lower for all upper teeth and for lower first bicuspid, cuspid and lateral incisors. Clinically, CB showed the lowest CAL values in every analyzed teeth, which was followed by CL. The presence of root concavities should not be underestimated either during clinical examination, diagnosis, prognosis, surgical or supportive periodontal treatment. Nevertheless, based on our results, it was not possible to assure that the differences found in CAL values were due to root concavities.

    The clinical efficacy of topical administration of standardised fermented papaya gel (SFPG), known to have antioxidant and anti-inflammatory properties, versus conventional therapy was evaluated in a group of 84 patients with moderate-to-severe periodontitis, randomly assigned to control group (n = 45) undergoing traditional pharmacologic/surgical protocols or to experimental group (n = 39), additionally treated with intragingival pocket SFPG (7 g) applications (15 min daily for 10 days). Patients undergoing SFPG treatment showed significant (P < 0.05), durable improvement of three major clinical indices of disease severity: reduced bleeding (day 7), plaque and gingival conditions (day 14), and consistent gingival pocket depth reduction (day 45). Proinflammatory nitric oxide metabolites reached normal values in plasma (day 14) and gingival crevicular fluid (GCF) at day 45 with SFPG applications compared to controls that did not reach normalisation. Levels of highly increased proinflammatory (IL-1B, IL-6) and suppressed anti-inflammatory (IL-10) cytokines normalised in the SFPG group by days 14 (plasma) and 45 (GCF), but never in the control group. Although not acting directly as antibiotic, SFPG acted in synergy with human granulocytes blocking adaptive catalase induction in S. aureus in response to granulocyte-derived oxidative stress, thus enhancing intracellular bacterial killing.

Materials and Methods: A total of 23 patients with non-adjacent probing pocket depths (PPDs ≥5mm were randomly assigned to CHX, CU and positive control irrigation groups and subjected to randomized single blinded clinical control trial. The clinical parameters bleeding on probing, redness, plaque index, PPD and microbiological parameter N-benzoyl-DL-arginine-2-naphthylamide (BANA test were evaluated at baseline, 1, 3 and 6 months interval. Results: At 1 month evaluation, CU group showed better results compared with the other groups. However, by the end of the study period CHX group showed the best results with as light recurrence in the CU group. The results of BANA test showed similar results for both CU and CHX group throughout the study period. Conclusion: The results of this study show a mild to moderate beneficiary effect of CU irrigation when used as an adjunct to Scaling and root planing. Further studies may be required using varied concentrations of the drug to improve the substantivity of the drug and also to prevent early re-colonization of periodontal pathogens.

    A total of 25 patients were treated with a nonsurgical periodontal treatment protocol (NSPTP) consisting of four appointments (three within 1 week and one approximately 30 days later). Nonsurgical periodontal instrumentation was implemented, with the adjunctive use of thermal diode lasers (wavelength of 808 or 980 nm). The patients were scheduled for recall visits every 3 months and reevaluated 1 year post-NSPTP. They were subsequently monitored at 4-month intervals for the remaining 2-year follow-up maintenance period. In total, 698 teeth (210 multirooted and 488 single-rooted) were included in the study. The mean bleeding on probing was 43% at baseline and decreased to 12% at 12 months and to 8% at 3 years. The initial ≥ 6-mm probing pocket depth (PPD) in single-rooted teeth decreased from 6.2 mm at baseline to a mean of 1.8 mm at 12 months and remained at 1.8 mm at 3 years, with a mean clinical attachment level (CAL) gain of 4.4 mm. In multirooted teeth, the PPD decreased from 6.7 mm to a mean of 3.9 mm at 12 months and 3.6 mm at 3 years, with a mean CAL gain of 2.9 mm. The mean overall recession was 0.3 mm at baseline, 0.1 mm at 1 year, and 0.3 mm at the 3-year follow-up. In the short-term followup period, uniform and consistent implementation of the NSPTP used here with adjunctive use of thermal diode lasers seemed to convey therapeutic benefits, stable periodontal soft tissue levels, and satisfactory esthetics in patients with moderate to severe chronic periodontitis. The present protocol is relevant as a treatment option for medically compromised patients, those who refuse or delay surgical treatment, or those who present with other limitations. PMID:26901297

    To investigate the correlation between postmenopausal osteoporosis (PMO) and the pathogenesis of periodontitis, ovariectomized rats were generated and the experimental periodontitis was induced using a silk ligature. The inflammatory factors and bone metabolic markers were measured in the serum and periodontal tissues of ovariectomized rats using an automatic chemistry analyzer, enzyme-linked immunosorbent assays, and immunohistochemistry. The bone mineral density of whole body, pelvis, and spine was analyzed using dual-energy X-ray absorptiometry and image analysis. All data were analyzed using SPSS 13.0 statistical software. It was found that ovariectomy could upregulate the expression of interleukin- (IL-)6, the receptor activator of nuclear factor- κB ligand (RANKL), and osteoprotegerin (OPG) and downregulate IL-10 expression in periodontal tissues, which resulted in progressive alveolar bone loss in experimental periodontitis. This study indicates that changes of cytokines and bone turnover markers in the periodontal tissues of ovariectomized rats contribute to the damage of periodontal tissues.

    2013-01-01

    Full Text Available Context: Antimicrobial proteins and peptides constitute a diverse class of host-defense molecules that act early to combat invasion and infection with bacteria and other microorganisms. Among the various antimicrobial peptides in the oral cavity, adrenomedullin (ADM, a cationic peptide, is found in gingival crevicular fluids (GCFs in amounts twice as high in periodontal disease sites as healthy sites. Studies have also shown that plasma levels of ADM increased in patients with type 2 diabetes mellitus as compared with controls. Aims: This clinico-biochemical study was undertaken to try to decipher the probable link between ADM, diabetes and periodontitis. Materials and Methods: The study comprised of 90 patients who were divided into three groups based on community periodontal index scores and diabetes status. Probing pocket depth and clinical attachment level were measured in all subjects. GCF was collected from all the participants using micropipettes and blood samples were collected from subjects in Groups III, for analysis of glycated hemoglobin. ADM levels were measured in GCF samples by the enzyme-linked immunosorbent assay. Statistical Analysis Used: The data obtained were subjected to analysis of variance, Bonferroni test and Pearson′s correlation. Results: An increase in GCF levels of ADM from periodontal health to disease and in periodontitis patients with type 2 diabetes was noted. Conclusions: Increase in GCF levels of ADM from periodontal health to disease and in periodontitis patients with type 2 diabetes reinforces the perio-systemic interlink concept.

    The purpose of the present study was to investigate the prevalence of adolescents with high periodontal risk and to identify factors with influence on the decision to refer a patient to a specialist clinic of Periodontology, on compliance rate and on treatment outcome. The investigation was conducted as a retrospective study on adolescents at age 13-17. In total, clinical examinations and risk evaluations according to caries- and periodontal risk were performed on 50347 adolescents in general dentistry at ages 13, 15 and 17 in 2007. Individuals with a high periodontal risk were included in the present investigation. A high periodontal risk was defined as presence of sites with periodontal pocket depths >6mm and loss of periodontal tissue support. Multiple logistic regression analyses were adopted to calculate the influence of the potential predictors on the investigated dependent variables. In total, 0.5% of the adolescents were found to have high periodontal risk. The diagnosis local periodontitis and the number of periodontal pockets with probing depths >6 mm were positively and significantly correlated to referral to a periodontist. Eighteen percent dropped out before the treatment was completed. Smokers had a significantly lower compliance than non-smokers. The success rate was significantly lower for individuals with many periodontal pockets and for those with the diagnosis local periodontitis. The prevalence of adolescents classified as having high periodontal risk was low. A large frequency of subjects dropped out before the periodontal treatment was completed, especially at the specialist clinics. PMID:24620506

    2012-01-01

    Full Text Available Background/Aim. Periodontitis is a local inflammatory process mediating destruction of periodontal tissues triggered by bacterial insult. However, this disease is also characterized by systemic inflammatory host responses that may contrbute, in part, to the recently reported increased risk for systemic diseases, including an altered lipid metabolism. On the other hand, many people in the world are affected by hyperlipidemia, which is a known risk faktor for atherosclerosis. The aim of this study was to determine the relationship between periodontal disease and blood lipid levels. Methods. A total of 50 patients with periodontitis included in this study had no documented history of recent acute coronary events. The healthy, non-periodontal subjects (comparison group comprised 25 subjects. All the patients were periodontology examined and completed a medical history. Dental plaque index, probing depth, gingival index bleeding on probing and clinical attechment levels were recorded. Blood samples were taken on admission for measurements of serum total cholesterol, triglycerides, hight density lipoprotein cholesterol (HDL-cholesterol, and low density lipoprotein cholesterol (LDL-cholesterol. Results. The obtained results showed that mean levels of cholesterol (6.09 ± 1.61 mmol/L, triglycerdes (2.19+1.67mmol/l and LDL cholesterol (4.09 ± 1.40 mmol/L in individuals with periodontitis were higer, and levels od HDL (1.43 ± 0.51 mmol/L was lower than those of individuals without periodontitis (4.86 ± 1.37; 1.14 ± 0.71; 3.18 ± 0.64; 1.53 ± 0.32 mmol/L, respectively. Conclusion. This study confirms a significant relationship between periodontal disease, regardless its intensity, and blood lipid levels in the studied population. The results imply that periodontitis may be a risk factor and may contribute to the pathogenesis of atherosclerosis and cardiovascular diseases (CVD. However, future prospective randomized studies have to determine whether

    Aim A double-blind randomized controlled trial to determine whether dietary supplementation with fruit/vegetable/berry juice powder concentrates, simultaneously with non-surgical periodontal therapy, improved 2-month treatment outcomes. Methods Volunteers with chronic periodontitis were randomly assigned to one of three groups: fruit/vegetable (FV), fruit/vegetable/berry (FVB) or placebo. Supplements were taken daily during non-surgical debridement and maintenance and outcomes assessed at 2, 5 and 8 months after completion. Primary outcomes were mean probing pocket depth (PPD), clinical attachment gain, % sites bleeding on probing (% BOP) at 2 months. Adherence and plasma β-carotene were determined. Results Sixty-one nutritionally replete (by serum biochemistry) volunteers enrolled and 60 (n = 20 per arm) completed the 2-month review. Clinical outcomes improved in all groups at 2 months, with additional improvement in PPD versus placebo for FV (p < 0.03). Gingival crevicular fluid volumes diminished more in supplement groups than placebo (FVB; p < 0.05) at 2 months, but not at later times. The % BOP (5 months) and cumulative plaque scores (8 months) were lowered more in the FV group (p < 0.05). Conclusions Adjunctive juice powder concentrates appear to improve initial pocket depth reductions in nutritionally replete patients, where plasma micronutrient bioavailability is attainable. Definitive multicentre studies in untreated and treated patients are required to ascertain the clinical significance of such changes. PMID:22093005

    Full Text Available Aggressive periodontitis, although not rare, is a fairly unknown condition. Little is known about its optimal management. While majority of patients with common forms of periodontal disease respond predictably well to conventional therapy (oral hygiene instructions (OHI, non-surgical debridement, surgery, and Supportive Periodontal therapy (SPT, patients diagnosed with aggressive form of periodontal disease often do not respond predictably/favorably to conventional therapy owing to its complex multi-factorial etiology. Protocols for treating aggressive periodontitis are largely empirical. There is compelling evidence that adjunctive antibiotic treatment frequently results in more favorable clinical response than conventional therapy alone. This article mainly focuses on the role of adjunct use of pharmacological agents in improving the prognosis and treatment outcome of aggressive periodontitis patients.

Periodontal disease has been convincingly emerging as an important independ...

  7. Clinical use of dental radiography in the diagnosis of interproximal caries and periodontal disease

    International Nuclear Information System (INIS)

    The purpose of the present study was to investigate associations between periapical and bitewing techniques by assessing the crestal alveolar bone. This article also reports the ability of these two techniques to correctly detect evidence of interproximal dental caries, and comparison between the interproximal overlapping of teeth. Bitewing and periapical radiographs were used from posterior quadrants of 243 dental students in Seoul National University. The distance from cemento-enamel junction to the alveolar crest (CEJ-AC) was measured for each proximal surface from the distal of cuspid to the distal of second molar. Data were arranged according to the proximal surface examined, and bitewing and periapical measurements were compared using paired tests. The obtained results were as follows: 1. In maxilla, a significant ratio with a P value of 0.05 or les reached for 100% and in mandible, reached for 94%. 2. The anatomic limitations imposed on periapical radiographic technique, most often result in somewhat foreshortened radiographic images. This situation would tend to be accentuated by the anatomical restrictions of the hard palate. 3. Consequently, since the significant differences frequently exist between measurements obtained from bitewing and periapical techniques, it is importance to define which technique is used. 4. The number of the interproximal overlapping was the largest media side of the maxillary second molar, while the smallest at the distal side of the mandibular second premolar. And the overall number of the interproximal overlapping was more (538) in the periapical technique than in the bitewing technique (372). 5. The interproximal dental carious lesions were detected more (74) on the bitewing films than on the periapical ones (23). The fact was resulted from the small number of interproximal overlapping and relative easiness of obtaining horizontal angulation in taking the bitewing radiographs.

    2010-01-01

    Full Text Available Background: The development of periodontal disease has been thought to be associated with several restricted members of the oral anaerobic species, such as black-pigmented Porphyromonas species and Actinobacillus actinomycetemcomitans (Aa, in the subgingival environment. Apart from bacteria, certain viruses and fungi that are associated with periodontal disease are also present in the subgingival plaque . Materials and Methods: A randomized, double-blind, crossover split-mouth design was performed. A total of 16 patients suffering from generalized chronic periodontitis were selected for the study. The study period of 18 days was divided into two time-intervals, i.e. baseline (0 days to 7 th day, with a washout period of 4 days followed by a second time interval of 7 days. The use of ozone and chlorhexidine gluconate (CHX irrigation was randomized. Both the patient and the clinician evaluating the clinical parameters were blinded regarding the type of irrigation used. Results: The interpretation of clinical and microbial data is from baseline to 7 th day. A higher percentage of plaque index (12%, gingival index (29% and bleeding index (26% reduction was observed using ozone irrigation as compared to chlorhexidine. The percentile reduction of Aa (25% using ozone was appreciable as compared to no change in Aa occurrence using chlorhexidine. By using O 3 and chlorhexidine, there was no antibacterial effect on Porphyromonas gingivalis (Pg and Tannerella forsythensis. The antifungal effect of ozone from baseline (37% to 7 th day (12.5% was pronounced during the study period, unlike CHX, which did not demonstrate any antifungal effect. Conclusion: Ozone may be considered as an alternative management strategy due to its powerful ability to inactivate microorganisms. Also, there is growing evidence that ozone can be employed as a useful therapeutic agent in both dentistry and medicine.

    Gingivitis and chronic periodontitis are highly prevalent chronic inflammatory diseases. Gingivitis affects the majority of people, and advanced periodontitis is estimated to affect 5-15% of adults. The detection and diagnosis of these common diseases is a fundamentally important component of oral health care. All patients should undergo periodontal assessment as part of routine oral examination. Periodontal screening using methods such as the Basic Periodontal Examination/Community Periodontal Index or Periodontal Screening Record should be performed for all new patients, and also on a regular basis as part of ongoing oral health care. If periodontitis is identified, full periodontal assessment is required, involving recording of full mouth probing and bleeding data, together with assessment of other relevant parameters such as plaque levels, furcation involvement, recession and tooth mobility. Radiographic assessment of alveolar bone levels is driven by the clinical situation, and is required to assess bone destruction in patients with periodontitis. Risk assessment (such as assessing diabetes status and smoking) and risk management (such as promoting smoking cessation) should form a central component of periodontal therapy. This article provides guidance to the oral health care team regarding methods and frequencies of appropriate clinical and radiographic examinations to assess periodontal status, to enable appropriate detection and diagnosis of periodontal conditions.

    Early detection of disease plays a crucial role in successful therapy. Early diagnosis and management reduces the severity and possible complications of the disease process. To overcome this challenge, medical researchers are devoted to finding molecular disease biomarkers that reveal a hidden lethal threat before the disease becomes complicated. Saliva, an important physiologic fluid, containing a highly complex mixture of substances, is rapidly gaining popularity as a diagnostic tool. Periodontal disease is a chronic disease of the oral cavity comprising a group of inflammatory conditions affecting the supporting structures of the dentition. In the field of periodontology, traditional clinical criteria are often insufficient for determining sites of active disease, for monitoring the response to therapy, or for measuring the degree of susceptibility to future disease progression. Saliva, as a mirror of oral and systemic health, is a valuable source for clinically relevant information because it contains biomarkers specific for the unique physiologic aspects of periodontal diseases. This review highlights the various potentials of saliva as a diagnostic biomarker for periodontal diseases.

    HIV/Aids patients present a change of microbiota associated with host immunodeficiency. Photodynamic therapy (PDT) showed as a promising and viable alternative in reducing microbiota. Present study evaluate effectiveness of photodynamic therapy in periodontal disease of AIDS patients with highly activity antiretroviral therapy (HAART) failure, measuring the clinical periodontal parameters and periodontal microbiota. Twelve patients with HARRT resistance (R group) divided into two groups (control and PDT) and 12 patients with no HAART resistance (NR group) divided into two groups (control and PDT). The results show the difference in baseline of CD4 cells count, NR group 640.0 +/- 176.2 cells/mm3 R group and 333.3 +/- 205.8 cells / mm3 (pperiodontal parameters (PD and CAL), PDT was more effective than the control group only in the NR group (p periodontal parameters between the both R groups (p>0.05%). Microbiological evaluation in R group presents a general reduction in the Aa at 3 and 6 months. Furthermore, demonstrated a reduction of Pg in all groups at 6 months and in R group at 3 months. The impact assessment of photodynamic therapy in patients with different levels of immunosuppression determined that the combination of mechanical periodontal treatment with photodynamic therapy in patients with HAART failure did not cause additional benefits. Therefore, PDT in this study could not been indicated in HAART resistance patients.

    A 34 years old male patient was referred to our clinic for restorative dental treatment. During detailed consultation and dental examination a relatively rare form of periodontal disease had been diagnosed. Intraoral examination included recording of dental and periodontal status. Based on patient's dental history, measurements of probing pocket depths (PPD), clinical attachment level (CAL), and also the X-ray findings, Localized Aggressive Periodontitis (LAP) unknown by the patient was diagnosed. After patient's consent the comprehensive treatment plan covered the dental prevention, periodontal non-surgical and surgical therapy and rehabilitation. The treatment started with oral hygienic instruction, motivation then supra- and subgingival scaling and rootplaning. Later extraction and elective root canal treatment were performed, followed by open flap periodontal surgery combined with hemisection of two molars. After a full mouth conservative restorative therapy, function and esthetics were restored by fix dental prostheses. This case is a good example to underline the importance of periodontal examination during the dental screening and dental status recording for each patients showing up at dental clinics. Otherwise in many cases this asympthomatic disease can remain undetected. PMID:26863818

    Periodontal diseases, which result from inflammation of tooth supporting tissues, are highly prevalent worldwide. Myeloperoxidase (MPO), from certain white blood cells in saliva, is a biomarker for inflammation. We report our study on the salivary MPO activity and its association with severity of periodontal diseases among Thai patients. Periodontally healthy subjects (n = 11) and gingivitis (n = 32) and periodontitis patients (n = 19) were enrolled. Assessments of clinically periodontal parameters were reported as percentages for gingival bleeding index (GI) and bleeding on probing (BOP), whereas pocket depth (PD) and clinical attachment loss (CAL) were measured in millimeters and then made to index scores. Salivary MPO activity was measured by colorimetry using 3,3'-diaminobenzidine as substrate. The results showed that salivary MPO activity in periodontitis patients was significantly higher than in healthy subjects (p = 0.003) and higher than in gingivitis patients (p = 0.059). No difference was found between gingivitis and healthy groups (p = 0.181). Significant correlations were observed (p < 0.01) between salivary MPO activity and GI (r = 0.632, p < 0.001), BOP (r = 0.599, p < 0.001), PD (r = 0.179, p = 0.164), and CAL (r = 0.357, p = 0.004) index scores. Sensitivity (94.12%), specificity (54.55%), and positive (90.57%) and negative (66.67%) predictive values indicate that salivary MPO activity has potential use as a screening marker for oral health of the Thai community.

    Full Text Available Background and Objectives. Matrix metalloproteinases degrade extracellular membrane and also release bioactive fragments and growth factors, thus influencing fundamental biological and pathological processes. Epilysin (MMP-28 differs from most other MMPs as it is expressed in a number of normal tissues, suggestive of functions in tissue homeostasis. The aim of the present study was to quantitatively evaluate and compare the mRNA expression of epilysin (MMP-28 in gingival tissues of healthy patients and of patients affected by chronic or aggressive periodontitis. Methods. A total of 60 subjects, 20 periodontally healthy subjects, 20 with chronic periodontitis, and 20 with aggressive periodontitis, were included in this study. Periodontal status was evaluated by measuring gingival index, probing depth and clinical attachment level. mRNA expression of MMP-28 was determined by quantitative real-time reverse transcriptase polymerase chain reaction (RT-PCR in gingival tissue samples collected. Results. Relative quantification of mRNA expression of MMP-28 was highest in healthy tissues ( when compared to subjects with chronic periodontitis ( and aggressive periodontitis (, but the difference was not statistically significant. Conclusion. mRNA expression of MMP-28 was highest in healthy tissues when compared to diseased periodontal tissues suggesting that MMP-28 could act as a biomarker for periodontal health.

    Several studies have suggested an increase of cardiovascular disease (CVD) risk on periodontitis patients. An enhancement has been demonstrated on both platelet activation and oxidative stress on periodontitis patients, which may contribute for this association. Therefore, the aim of this study was to evaluate the effects of non-surgical periodontal treatment on the l-arginine-nitric oxide (NO)-cyclic guanosine monophosphate (cGMP) pathway and oxidative status in platelets. A total of eight periodontitis patients and eight controls were included in this study. Clinical, laboratory and experimental evaluations were performed on baseline and 90 days after periodontal treatment (except for western blot analysis). The clinical periodontal evaluation included measurements of probing pocket depth (PPD), clinical attachment loss (CAL), % of sites with plaque and % of sites with bleeding on probing. We evaluated: l-[(3)H]arginine influx; nitric oxide synthase (NOS) and arginase enzymes activity and expression; expression of guanylate cyclase and phosphodiesterase-5 enzymes; cGMP levels; platelet aggregation; oxidative status through superoxide dismutase (SOD) and catalase activities, and measurement of reactive oxygen species (ROS) levels and C-reactive protein (CRP) levels. The initial results showed an activation of both l-arginine influx and via system y (+ )L associated with reduced intraplatelet cGMP levels in periodontitis patients and increased systemic levels of CRP. After periodontal treatment, there was a significant reduction of the % of sites with PPD 4-5mm, % of sites with CAL 4-5 mm, and an enhancement in cGMP levels and SOD activity. Moreover, CRP levels were reduced after treatment. Therefore, alterations in the intraplatelet l-arginine-NO-cGMP pathway and oxidant-antioxidant balance associated with a systemic inflammatory response may lead to platelet dysfunction, which may contribute to a higher risk of CVD in periodontitis.

    An investigation was made of applying pulsed (lambda) equals 0.89 micrometers laser radiation in the treatment for early diagnosed periodontitis. The investigation was made on 65 patients (47 patients constituted the experimental group and 18 patients constituted a control group) affected by periodontitis. Clinical and functional tests revealed that laser therapy produced a string effect on the course of the illness. It reduced bleeding, inflammation, and pruritus. However, it did not produce an affect on electroexcitation. Biomicroscopic examinations and periodontium rheography revealed that the gingival blood flow became normal after the course of laser therapy. The capillary permeability and venous congestion decreased, which was confirmed by the increased time of vacuum tests, raised gingival temperature, reduced tissue clearance, and increased oxygen tension. Apart from that, laser therapy subsided fibrinolysis, proteolytic tissue activity, and decreased the exudative inflammation of periodontium.

Twenty patients with chronic periodontitis and 15 healthy subjects were enrolled in this study. Clinical indices were recorded in a six-point measurement per tooth. From each patient samples of supra and subgingival plaque were taken separately from teeth with shallow, deep and very deep pockets. Samples of supragingival plaque and sulcular microflora were collected from the healthy subjects. All the samples were cultivated on different media at 37̊C in an anaerobic atmosphere for 7 days. All the suspect colonies were identified using a rapid ID 32 A system (bioMèrieux) and MALDI-TOF-MS analysis using an Autoflex II Instrument (Bruker Daltonics) together with in house developed identification software and a reference spectra database. A total of 977 strains were identified as Actinomyces. Actinomyces naeslundii/oris/johnsonii (430 isolates) was the most prevalent species and was found in all patients and in almost all of the healthy subjects. Significant differences (p=0.003) between the groups were found for Actinomyces odontolyticus/meyeri and Actinomyces israelii which were associated with periodontitis patients. Actinomyces dentalis was found in higher percentage (p=0.015) in the periodontitis group. Actinomyces gerencseriae and Actinomyces massiliensis were significantly more often found supragingivally than subgingivally (p=0.004, p=0.022, respectively) in the periodontitis group. Whether some Actinomyces species, definitely important plaque formers, are actively involved in the pathogenicity of chronic periodontitis needs further investigation. PMID:26324012

    This investigation was designed to determine the influence of different frequencies of tooth brushing on artificial periodontal defects in the beagle dog after a period of healing. In 12 beagle dogs, periodontal defects were created using elastic bands placed in the sulci below the gingival margin after having cut the dento-gingival fibres to the level of the alveolar bone crest. This active phase of creating defects lasted for 6 weeks. After removal of the elastic bands, the created defects were left undisturbed during the remainder of the pre-experimental period (12 weeks). 6 premolars in the lower jaw were used (2P2, 3P3, 4P4). After the pre-experimental period, the 12 dogs were distributed into 3 groups of 4 dogs each. Each group was brushed with a certain frequency, i.e., 7 times, 3 times or once a week. Registrations of plaque index, gingival index and probing depth using a constant force probe were carried out on approximal surfaces. The experiment lasted for 24 weeks. A brushing effect was calculated for each dog to include information on all within-dog and between-dog variations. It was shown in relation to artificially-induced periodontal defects in beagle dogs that after a period of healing, brushing 7 times a week is superior to brushing 3 times a week in establishing and maintaining gingival health.

    This investigation was designed to determine the influence of different frequencies of tooth brushing on artificial periodontal defects in the beagle dog shortly after creation. In 12 beagle dogs, periodontal defects were created using elastic bands placed in the sulci below the gingival margin after having cut the dento-gingival fibres to the level of the alveolar bone. This active phase of creating defects lasted for 6 weeks. 6 premolars in the lower jaw were used (2P2, 3P3, 4P4). After removal of the elastic bands, the 12 dogs were distributed into 3 groups of 4 dogs each. Each group was brushed with a certain frequency, i.e., 7 times, 3 times or once a week. Plaque index, gingival index and probing depth, using a constant force probe, were assessed interproximally. The experiment lasted for 24 weeks. For hypothesis testing, a brushing effect was calculated for each dog. Furthermore, an analysis was performed based on the absolute scores at week 24. From the statistical analysis, it was concluded that in artificially-induced periodontal defects in beagle dogs immediately after creation, brushing 7 times a week is superior to brushing 3 times a week to establish and maintain gingival health.

    Full Text Available Background: Periodontitis is multifactorial in nature. The various determinants of periodontal disease are age, sex, race, socioeconomic status, and risk factors including tobacco usage and oral hygiene status. However, there is inconsistent epidemiological data on the periodontal status of subjects living in high-fluoride areas. The aim of the study was to investigate the effect of dental fluorosis on the periodontal status using community periodontal index of treatment needs (CPITN, as a clinical study. The purpose of this study is to determine the periodontal status using CPITN index in a population aged between 15 and 74 years residing in the high-fluoride areas of Davangere district. The possible reasons for the susceptibility of this population to periodontal disease are discussed. Materials and Methods: 1029 subjects, aged between 15 and 74 years suffering from dental fluorosis were assessed for their periodontal status. Clinical parameters recorded were OHI-S to assess the oral hygiene status, Jackson′s fluorosis index to assess the degree of fluorosis and CPITN index to assess the periodontal status where treatment need was excluded. Results: Gingivitis and periodontitis were more common in females (65.9% and 32.8%, respectively than in males (75.1% and 24.2%, respectively. Periodontitis was significantly more common in females. As the age advanced from 15 to 55 years and above, gingivitis reduced from 81.0 to 42.9% and periodontitis increased steadily from 18.0 to 57.1%, which was significant. Periodontitis was high in subjects with poor oral hygiene (81.3%, compared to those with good oral hygiene (14.5%, which was significant. As the degree of fluorosis increased, severity of gingivitis reduced and periodontitis increased, i.e., with A degree fluorosis, gingivitis was 89.4% and periodontitis 8.5%, but with F degree fluorosis the former was 64% and the latter 35.8%, which was statistically significant. Conclusion: The results

    Full Text Available Abstract The aims of this study were to assess the prevalence of periodontal conditions in the Uruguayan adult and elderly population and its association with socioeconomic and behavioral characteristics. Data from adults (35-44, n = 358 and elderly (65-74, n = 411 who participated in the first National Oral Health Survey, Uruguay, 2011, were used. The survey included a household questionnaire addressing socioeconomic characteristics, and tobacco use. Bleeding on probing (BOP, periodontal pockets (CPI and clinical attachment loss (CAL were measured by clinical examination. A multivariable analysis was carried out. Considering both age groups, the prevalence of mild/severe periodontal disease was 21.8% and 9.12% for severe periodontal disease. Adjusted analyses revealed an association between high education and all outcomes. Attendance at dental services was negatively associated with BOP and mild to severe periodontitis. Periodontal outcomes were higher in disadvantaged socioeconomic groups. Tobacco consumption has a strong association with periodontal disease in the elderly.

    Objective: The aim of this study was to investigate subgingival infection frequencies ofPorphyromonas gtngivalis and Actinobacillus actinomycetemcomitans strains with genetic variation in Chinese chronic periodontitis (CP) patients and to evaluate its correlation with clinical parameters. Methods: Two multiplex polymerase chain reaction (PCR) assays were developed to detect the 16SrDNA, collagenase (prtC) and fimbria (fimA) genes of P. gingivalis and the 16SrDNA, leukotoxin (lktA) and fimbria-associated protein (lap) genes ofA. actinomycetemcomitans in 60 sulcus samples from 30 periodontal healthy subjects and in 122 subgingival plaque samples from 61 patients with CP. The PCR products were further T-A cloned and sent for nucleotide sequence analysis. Results: The 16SrDNA, prtC andfimA genes ofP. gingivalis were detected in 92.6%, 85.2% and 80.3% of the subgingival plaque samples respectively, while the 16SrDNA, lktA andfap genes ofA. actinomycetemcomitans were in 84.4%,75.4% and 50.0% respectively. Nucleotide sequence analysis showed 98.62%~100% homology of the PCR products in these genes with the reported sequences. P. gingivalis strains with prtC+/fimA+ and A. actinomycetemcomitans with lktA+ were predominant in deep pockets (>6 mm) or in sites with attachment loss ≥5 mm than in shallow pockets (3~4 mm) or in sites with attachment loss ≤2 mm (P<0.05). P. gingivalis strains with prtC+/fimA+ also showed higher frequency in gingival index (GI)=3than in GI= 1 group (P<0.05). Conclusion: Infection of P. gingivalis with prtC+/fimA+ and A. actinomycetemcomitans with lktA+correlates with periodontal destruction of CP in Chinese. Nonetheless P. gingivalis fimA, prtC genes and A. actinomycetemcomitans IktA gene are closely associated with periodontal destruction, while A. actinomycetemcomitansfap gene is not.

    Full Text Available Epidemiological data on the periodontal health and oral hygiene practices of young individuals in Latin America are limited. This study was conducted in a sample of 355 first-year students randomly selected from 3,251 new students entering the largest university in Colombia. Participants received a periodontal examination and were interviewed about oral hygiene practices. Specifically, this study assessed the relationship between oral hygiene practices (including smoking tobacco and plaque accumulation and/or periodontal bleeding on probing (BOP. Participants had extensive plaque accumulation and BOP, with a mean O´Leary plaque index of 56% and mean BOP of 37%. Both measures were higher for proximal surfaces. Plaque indices of at least 50% were not associated with any oral hygiene factors; however, plaque index and use of dental floss were associated with a BOP of at least 50%. Frequency of tooth brushing was higher in female than in male participants. Only 5% of participants reported smoking tobacco. On average, participants had 2.7 ± 4.6 pockets of at least 4 mm (18% of participants had ≥ 5 and 9% of participants had ≥ 10 pockets of this depth, respectively. On average, participants had 2.1 ± 4.4 sites with clinical attachment loss of at least 2 mm (15% and 6% of participants had ≥ 5 and ≥ 10 sites with this level of loss. Only 8% of participants were diagnosed with moderate periodontitis, and no participants were diagnosed with severe periodontitis. In conclusion, although participants had high levels of plaque and BOP, signs of advanced destructive periodontal disease were minimal.

    Full Text Available Objective: An inter-relationship between periodontal disease and systemic health has been suspected for centuries, but evidence to explain the connection has only been elucidated in the past few decades. Among the systemic diseases, end stage renal disease has been shown to affect not only the general health of the patient but also oral and periodontal health. This study was undertaken to gain an insight into whether duration of dialysis therapy influences the oral and periodontal health of these patients and also to see if these parameters reflect their biochemical values. Materials and Methods: The study was conducted on 75 patients undergoing dialysis and a control group of 25 subjects. The study group was divided into three subgroups depending upon the duration of dialysis. Oral hygiene and periodontal disease status were measured by Simplified Oral Hygiene Index by Greene and Vermillion and Periodontal Disease Index by Ram-fjord. Biochemical parameters measured were blood urea nitrogen and salivary urea levels. Comparison of these parameters was made between the study and control groups through analysis of variance (ANOVA and student′s t-test. Results: Prevalence of periodontal disease was evident in the dialysis group. Oral hygiene status was poor in comparison with the control group. Clinical and biochemical parameters showed statistically significant difference between the groups rather than within the groups. Conclusion: Oral and periodontal health appeared to be compromised. Their deteriorating general health is anticipated to cause negligence towards oral health care. This population needs comprehensive oral and periodontal care right from the diagnosis of chronic renal failure. There exists a need for communication between nephrologists and oral health care professionals. Longitudinal studies warranted in this regard.

    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.

    2016-01-01

    Full Text Available The regeneration and integration of multiple tissue types is critical for efforts to restore the function of musculoskeletal complex. In particular, the neogenesis of periodontal constructs for systematic tooth-supporting functions is a current challenge due to micron-scaled tissue compartmentalization, oblique/perpendicular orientations of fibrous connective tissues to the tooth root surface and the orchestration of multiple regenerated tissues. Although there have been various biological and biochemical achievements, periodontal tissue regeneration remains limited and unpredictable. The purpose of this paper is to discuss current advanced engineering approaches for periodontal complex formations; computer-designed, customized scaffolding architectures; cell sheet technology-based multi-phasic approaches; and patient-specific constructs using bioresorbable polymeric material and 3-D printing technology for clinical application. The review covers various advanced technologies for periodontal complex regeneration and state-of-the-art therapeutic avenues in periodontal tissue engineering.

    Full Text Available Background: The closure of the periodontal flaps post-surgery is a necessity for attainment of a primary union between the flap margins and the establishment of a healthy dentogingival junction. N-butyl cyanoacrylate is a tissue adhesive, which can be used for the closure of the incised wounds to overcome the problems associated with conventional suture materials like silk. Objective: The present study was carried out to assess the healing of the periodontal flaps when closed with the conventional silk sutures and N-butyl cyanoacrylate. Materials and Methods: The study was carried out on 24 patients who needed flap surgical procedure for pocket therapy. Results: It was found that healing with the cyanoacrylate is associated with less amount of inflammation during the first week when compared with silk. However, over a period of 21 days to 6 weeks, the sites treated with both the materials showed similar healing patterns. Conclusion: It can be concluded that cyanoacrylate aids in early initial healing.

    Full Text Available Background: The ultimate goal of periodontal therapy entails regeneration of the periodontal tissues lost as a consequence of periodontitis. Predictable correction of vertical osseous defects has however posed as a constant therapeutic challenge. The aim of our present study is to evaluate the relative efficacy of demineralized freeze-dried bone allograft (DFDBA vs anorganic bovine bone xenograft (ABBX in the treatment of human infrabony periodontal defects. Materials and Methods: 15 patients with 30 bilaterally symmetrical defect sites in either of the arches, in the age group of 25-50 years were selected as part of split-mouth study design. Defect-A (right side was grafted with DFDBA while Defect-B (left side was grafted with ABBX. Various clinical and radiographic parameters viz. probing depth(PD, clinical attachment level(CAL and linear bone fill were recorded preoperatively, 12- & 24-weeks postoperatively. Results: Both defect-A & defect-B sites exhibited a highly significant reduction in probing depth, and gain in clinical attachment level and linear bone fill at 12-weeks & at the end of 24-weeks. Comparative evaluation between the study groups revealed a statistically non-significant reduction in probing depth (P<0.1 and mean gain in linear bone fill (P<0.1. However, there was a statistically significant gain in clinical attachment level (P <0.05 in Defect-A (CD=0.356 as compared to Defect-B (CD=0.346. Conclusions: Within the limits of this study, both the materials viz. ABBX and DFDBA are beneficial for the treatment of periodontal infrabony defects. Both the materials were found to be equally effective in all respects except the gain in attachment level, which was found to be more with DFDBA. Long-term studies are suggested to evaluate further the relative efficacy of the two grafts.

    Objective: To evaluate the correlation of chronic periodontitis in tropical area and IFN-γ, IL-10 and IL-17 levels. Methods: One hundred and forty-eight patients and one hundred and thirty-two healthy control subjects were included in the study. Clinical parameters (PI, GI and PD) and GCF levels of IFN-γ, IL-10 and IL-17 were measured at baseline, week 8, week 16 and week 24 after mechanical removal of dental plaque. IFN-γ and IL-10 were determined with ELISA methods and IL-17 was determined with the cytometric bead array. Results: Removal of dental plaque resulted in improvement in all clinical parameters. Meanwhile, GCF IL-17 declined to control levels, while GCF IFN-γ and IL-10 levels remained unchanged. Conclusions: The decline of GCF IL-17 levels in patients with resolution of periodontitis suggests that IL-17 is involved in the periodontal inflammatory process.

    Full Text Available Geralmente o tratamento ortodôntico de pacientes adultos apresenta várias limitações, dentre as mais freqüentes podemos citar a perda exagerada do suporte ósseo, e a dificuldade de se obter uma ancoragem satisfatória devido às perdas de vários elementos dentários. No presente artigo, baseado na experiência clínica e na literatura consultada, procurou-se mostrar que é possível tratar de maneira eficiente esses casos, com uma abordagem multidisciplinar e adequação da mecânica ortodôntica à necessidade de cada indivíduo em particular. No caso clínico exposto, a paciente V.M., adulta, necessitava de tratamento odontológico envolvendo várias especialidades, incluindo a Ortodontia, que tinha como objetivo principal a intrusão e retração dos elementos 21 e 22. Após adequação do meio bucal, com a execução das extrações e restaurações necessárias, controle da doença periodontal e instituição de ótima higiene oral, foi iniciado o tratamento ortodôntico. Um sistema de ancoragem diferenciado foi aplicado, tentando superar a deficiência no número de unidades dentárias de suporte. Além disso, através da incorporação de "T-loops" aos arcos utilizados, procurou-se alcançar um bom controle na aplicação das forças necessárias à movimentação, evitando assim danos adicionais ao periodonto. Com esses cuidados, foi possível a obtenção de uma movimentação ortodôntica eficiente, com um real ganho funcional e estético para a paciente.Usually the orthodontic treatment of adults is quite limited, either in view of an exaggerated reduction in bone support, or due to the lack of anchoring points, when several dental elements having been lost. It is believed that these cases can be treated in an effective orthodontic way with a multidiscipline approach, tailored to each particular individual's mechanical needs. In this clinical case V.M, the patient, an adult, needed dental treatment involving several specialties

    Full Text Available Introduction Periodontal disease is related to the chronic inflammation involving the supporting structures of the teeth (periodontium. Beginning and progression of disease are closely associated with the presence of anaerobic Gram negative bacteria in the gingival crevice. Because of the complexity of this flora, its identification requires either traditional methods (i.e. microscopy and cultural methods or molecular approach (PCR, Polymerase Chain Reaction in order to achieve results that may be useful from a clinical point of view.We have studied the flora from periodontal pockets of 41 subjects with a clinical diagnosis of periodontitis. Methods The subgingival samples were collected using sterile paper points inserted subgingivally and inoculated onto appropriate plating media: blood agar, kanamycin vancomycin laked blood (KVLB, and NOS medium (New Oral Spirochetes.After incubation in anaerobic environment, a detailed colony description was recorded in particular with regard to size, shape, color, and pigment.The identification was performed by API20 system (bioMérieux. Molecular study was carried out by PCR method, using whole genomic DNA. Results Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythensis, and Treponema denticola were the most commonly strains isolated. Conclusions Both traditional and molecular approach are needed to identify the bacterial flora associated with periodontal disease. This approach represents an important strategy to either support the clinical diagnosis or control the extent of the disease. Furthermore, the possibility to evaluate the susceptibility pattern of antibiotic resistance among bacterial isolates might be important in view of the new antibiotic resistance recently described for those periodontal bacteria.

    Emblica officinalis fruit possesses varied medicinal properties including cytoprotective antimicrobial, antioxidant, antiresorptive and antiinflammatory activity. The present study aimed to investigate the effect of subgingival application of indigenously prepared E. officinalis (Amla) sustained-release gel adjunctive to scaling and root planing (SRP) on chronic periodontitis. Forty-six patients (528 sites) were randomly assigned to control group (23;264): SRP +placebo gel and test group (23;264): SRP + 10% E. officinalis gel application. Periodontal parameters: plaque index, gingival index, probing pocket depth (PPD), clinical attachment level (CAL) and modified sulcus bleeding index (mSBI) were assessed at baseline, 2 and 3-month post-therapy. Forty patients (470 sites) completed the trial. When test and control sites were compared, significantly more reduction in mean PPD, mSBI, number of sites with PPD = 5-6 mm, PPD ≥ 7 mm, CAL ≥ 6 mm and greater CAL gain were achieved in test sites at 2- and 3-month post-therapy (p < 0.05). Locally delivered 10% E. officinalis sustained-release gel used as an adjunct to SRP may be more effective in reducing inflammation and periodontal destruction in patients with chronic periodontitis when compared with SRP alone.

    The etiologic role of oral treponemes in human periodontitis is still under debate. Although seen by dark-field microscopy in large numbers, their possible role is still unclear since they comprise some 60 different phylotypes, most of which are still uncultured. To determine their status as mere commensals or opportunistic pathogens, molecular epidemiological studies are required that include both cultured and as-yet-uncultured organisms. Here we present such data, comparing treponemal populations from chronic periodontitis (CP) or generalized aggressive periodontitis (GAP) patients. As a periodontitis-resistant (PR) control group, we included elderly volunteers with more than 20 natural teeth and no history of periodontal treatment and no or minimal clinical signs of periodontitis. Almost every treponemal phylotype was present in all three groups. For most treponemes, the proportion of subjects positive for a certain species or phylotype was higher in both periodontitis groups than in the PR group. This difference was pronounced for treponemes of the phylogenetic groups II and IV and for Treponema socranskii and Treponema lecithinolyticum. Between the periodontitis groups the only significant differences were seen for T. socranskii and T. lecithinolyticum, which were found more often in periodontal pockets of GAP patients than of CP patients. In contrast, no difference was found for Treponema denticola. Our findings, however, strengthen the hypothesis of treponemes being opportunistic pathogens. It appears that T. socranskii, T. lecithinolyticum and group II and IV treponemes may represent good indicators for periodontitis and suggest the value of the respective probes for microbiological diagnosis in periodontitis subjects.

    Aggressive periodontitis is diagnosed mainly by clinical and radiographic examination. Diagnosis in the primary dentition indicates a choice between conservative and radical treatment that involves extractions, depending on the severity of the case. The purpose of this report was to present a case of aggressive periodontitis in a systemically healthy child and to discuss the periodontal and orthodontic aspects. A 7-year-old girl presented with bleeding on probing of approximately half of the dentition, deep periodontal pockets around all primary molars, and increased tooth mobility. An individual oral hygiene program was initiated. The primary maxillary right molar and all primary mandibular molars were extracted, and clear vacuum-formed removable retainers were fabricated and used as space maintainers. The patient was followed longitudinally for 2 years, and no space loss was recorded. Clear vacuum-formed removable retainers mainly involve occlusal crown attachment and, therefore, decrease the risk of plaque accumulation, gingival irritation, and aggressive periodontitis in the permanent dentition.

    Metabolic syndrome, a cluster of 3 or more risk factors for cardiovascular disease, is associated with periodontal disease, but few studies have been prospective in design. This study's aim was to determine whether metabolic syndrome predicts tooth loss and worsening of periodontal disease in a cohort of 760 men in the Department of Veterans Affairs Dental Longitudinal Study and Normative Aging Study who were followed up to 33 y from 1981 to 2013. Systolic and diastolic blood pressures were measured with a standard mercury sphygmomanometer. Waist circumference was measured in units of 0.1 cm following a normal expiration. Fasting blood samples were measured in duplicate for glucose, triglyceride, and high-density lipoprotein. Calibrated periodontists served as dental examiners. Periodontal outcome events on each tooth were defined as progression to predefined threshold levels of probing pocket depth (≥5 mm), clinical attachment loss (≥5 mm), mobility (≥0.5 mm), and alveolar bone loss (≥40% of the distance from the cementoenamel junction to the root apex, on radiographs). Hazards ratios (95% confidence intervals) of tooth loss or a periodontitis event were estimated from tooth-level extended Cox proportional hazards regression models that accounted for clustering of teeth within individuals and used time-dependent status of metabolic syndrome. Covariates included age, education, smoking status, plaque level, and initial level of the appropriate periodontal disease measure. Metabolic syndrome as defined by the International Diabetes Federation increased the hazards of tooth loss (1.39; 1.08 to 1.79), pocket depth ≥5 mm (1.37; 1.14 to 1.65), clinical attachment loss ≥5 mm (1.19; 1.00 to 1.41), alveolar bone loss ≥40% (1.25; 1.00 to 1.56), and tooth mobility ≥0.5 mm (1.43; 1.07 to 1.89). The number of positive metabolic syndrome conditions was also associated with each of these outcomes. These findings suggest that the metabolic disturbances that

    Aim: This study aims to compare the periapical healing of teeth with asymptomatic apical periodontitis treated either by conventional apical preparation (CAP) or apical clearing technique (ACT). Materials and Methods: Twenty subjects with bilateral nonvital similar teeth exhibiting comparable periapical index (PAI) score were enrolled and randomly allocated. Group I (CAP, n = 20): Apical preparation three sizes greater (master apical file [MAF]) than the first binding file at the established working length. Group II (ACT, n = 20): Apical preparation three sizes greater than the MAF that was followed by dry reaming. Root canal therapy was accomplished in single-visit for all the teeth. They were pursued radiographically at 3, 6, 9 and 12 months. Pre- and post-treatment PAI scores were compared. To ascertain the proportion of healed teeth between the two groups, McNemar Chi-square test was applied. Results: At 3, 6, and 9 months’ time interval the proportion of healed teeth for Group II (ACT) was greater in comparison to Group I (CAP) (P < 0.05). However, at 12 months follow-up period this difference was not significant (P = 0.08). Conclusion: ACT enhanced the healing kinetics. However, the long-term (12 months) radiographic outcome was similar for either technique. PMID:27656054

    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.

    Objective To explore the microorganism infection in combined periodontal source of periodontal-en-dodontic lesions. Methods A total of 38 patients (78 teeth, observation group) with combined periodontal source of periodontal-endodontic lesions and 38 orthodontic patients (78 teeth, control group) from January to December 2013 were recruited in this study. The samples of periodontal pocket and root canal were detected by PCR-DGGE ( Polymerase Chain Reaction-denaturing gradient gel electrophoresis) for microorganism species, and the microorganism infection was also an-alyzed. Results The isolation rate of microorganism in observation group was significantly higher than that in control group (P<0. 05). There were Campylobacter (34 teeth), Actinomyces (42 teeth), Fusobacterium (28 teeth), Enter-obacter (19 teeth) and Haemophilus (14 teeth) in the observation group, while Neisseria (8 teeth), Actinomyces (6 teeth) and Campylobacter (3 teeth) in control group. In observation group, 14. 33%-57. 85% of strain bands of perio-dontal pocket were same with those of root canal in the same tooth, but 1. 32%-67. 55% of strain bands of root canal did not exist in periodontal pocket in the same tooth; 1. 21%-4. 38% of strain bands of periodontal pocket in observation group existed in the same position tooth of root canal in control group, but 0-0. 57% of strain bands in control group did not exist in the same position tooth of root canal in observation group. The combined periodontal source of periodontal-en-dodontic lesions and infection were closely related with Campylobacter, Actinomyces, Fusobacterium, Enterobacter and Haemophilus (r=0. 232, P<0. 05). Conclusion The combined periodontal source of periodontal-endodontic lesions is closely related with the microorganism infection, and periodontal source and dental pulp source of periodontal-endodontic lesions are partly similar. Clinicians may improve the cure rate by considering microorganism infection types.%目的:探讨牙

    Full Text Available Abstract Background In periodontitis, treatment aimed at controlling the periodontal biofilm infection results in a resolution of the clinical and histological signs of inflammation. Although the cell types found in periodontal tissues following treatment have been well described, information on gene expression is limited to few candidate genes. Therefore, the aim of the study was to determine the expression profiles of immune and inflammatory genes in periodontal tissues from sites with severe chronic periodontitis following periodontal therapy in order to identify genes involved in tissue homeostasis. Gingival biopsies from 12 patients with severe chronic periodontitis were taken six to eight weeks following non-surgical periodontal therapy, and from 11 healthy controls. As internal standard, RNA of an immortalized human keratinocyte line (HaCaT was used. Total RNA was subjected to gene expression profiling using a commercially available microarray system focusing on inflammation-related genes. Post-hoc confirmation of selected genes was done by Realtime-PCR. Results Out of the 136 genes analyzed, the 5% most strongly expressed genes compared to healthy controls were Interleukin-12A (IL-12A, Versican (CSPG-2, Matrixmetalloproteinase-1 (MMP-1, Down syndrome critical region protein-1 (DSCR-1, Macrophage inflammatory protein-2β (Cxcl-3, Inhibitor of apoptosis protein-1 (BIRC-1, Cluster of differentiation antigen 38 (CD38, Regulator of G-protein signalling-1 (RGS-1, and Finkel-Biskis-Jinkins murine osteosarcoma virus oncogene (C-FOS; the 5% least strongly expressed genes were Receptor-interacting Serine/Threonine Kinase-2 (RIP-2, Complement component 3 (C3, Prostaglandin-endoperoxide synthase-2 (COX-2, Interleukin-8 (IL-8, Endothelin-1 (EDN-1, Plasminogen activator inhibitor type-2 (PAI-2, Matrix-metalloproteinase-14 (MMP-14, and Interferon regulating factor-7 (IRF-7.

    Full Text Available In this study, A. actinomycetemcomitans, B. forsythus, P. gingivalis and F. nucleatum were identified from subgingival plaque from 50 periodontal patients and 50 healthy subjects. Subgingival clinical samples were collected with sterilized paper points and transported in VMGA III. From all the diluted clinical samples (1:10, DNA was obtained by boiling, and after centrifugation the supernatant was used as template. Specific primers for each bacterial species were used in PCR. PCR amplification was sensitive to identify these organisms. PCR products from each species showed a single band and can be used to identify periodontal organisms from clinical specimens. PCR detection odds ratio values for A. actinomycetemcomitans and B. forsythus were significantly associated with disease showing a higher OR values for B. forsythus (2.97, 95% CI 1.88 - 4.70. These results suggest a strong association among the studied species and the periodontal lesion.Em nosso estudo quatro periodontopatógenos foram isolados e identificados de placas subgengivais de 50 pacientes com doença periodontal e de 50 indivíduos sadios.

    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

    The ability to track and report long-term outcomes, especially mortality, is essential for advancing clinical research. The purpose of this study was to present a framework for assessing the quality of mortality information in clinical research databases. Using the clinical data warehouse (CDW) at Columbia University Medical Center as a case study, we measured: 1) agreement in vital status between our institution's patient registration system and the U.S. Social Security Administration's Death Master File (DMF), 2) the proportion of patients marked as deceased according to the DMF records who had subsequent visits to our institution, and 3) the proportion of patients still living according to Columbia's CDW who were over 100 and 120 years of age. Of 33,295 deaths recorded in our institution's patient registration system, 13,167 (39.5%) did not exist in the DMF. Of 315,037 patients in our CDW who marked as deceased according to the DMF, 2.1% had a subsequent clinical encounter at our institution. The proportion of patients still living according to Columbia's CDW who were over 100 and 120 years of age was 43.6% and 43.1%, respectively. These measures may be useful to other clinical research investigators seeking to assess the quality of mortality data (1-4).

  14. Bromelain: A potential strategy for the adjuvant treatment of periodontitis

    Directory of Open Access Journals (Sweden)

    Felipe Rodolfo Pereira da Silva

    2016-01-01

    Full Text Available Introduction: Bromelain, a mixture of proteases derived from different parts of pineapple, has been described to have therapeutic benefits in a diversity of inflammatory diseases. Such effects are associated to its proteolytic activity. As one of the most common and multifactorial diseases, periodontitis is a bacterial infection that results from the damage to the integrity of the tissues around the tooth, which includes gingiva, periodontal ligament, and alveolar bone. In periodontitis, the recruitment of defense cells occurs, which releases several pro-inflammatory cytokines. At elevated levels, they can potentiate the alveolar bone loss. Studies have been conducted trying to alleviate the damage to the periodontium, however, the regeneration of the periodontal tissues is still limited. The Hypotheses: Based on previous studies showing that bromelain can act by decreasing the periodontal microorganism growth by proteolytically cleaving important cell surface molecules in leucocytes, by reducing neutrophils migration to periodontal sites, by downregulating the inflammation mediator levels, and by decreasing alveolar bone loss in the periodontitis. Evaluation of the Hypothesis: In a first moment, to evaluate this hypothesis, could be used two animal models: the ligature or bacteria inoculation induced periodontitis. If studies using animal models show encouraging results, appropriate clinical trials should be designed to evaluate the effect of bromelain as a complementary treatment for periodontal disease in humans, during the active phase or after the healing phase of mechanical therapy could be tested; to conduct a placebo-controlled study where health and periodontitis patients could be used.

    Objectives: Leptin is a hormone-like protein produced by the adipose tissue. It plays an important role in protection of host against inflammation and infection. Some studies have reported changes in leptin levels in the gingival crevicular fluid (GCF), saliva and blood serum of patients with periodontal disease compared to healthy individuals. The aim of the present study was to compare the salivary leptin levels in patients with advanced periodontitis and healthy individuals. Materials and Methods: In this case-control study, the salivary samples of healthy individuals and patients with advanced periodontitis with clinical attachment loss >5mm were obtained using a standardized method and the leptin levels were measured in the salivary samples by means of ELISA. The effects of the periodontal status and sex on the salivary leptin levels of both groups were statistically analyzed by two-way ANOVA. Results: The means ± standard deviation (SD) of salivary leptin levels in healthy subjects and patients with advanced periodontitis were 34.27±6.88 and 17.87±5.89 pg/mL, respectively. Statistical analysis showed that the effect of sex on the salivary leptin levels was not significant (P=0.91), while the effect of advanced periodontitis on the salivary leptin levels was significant compared to healthy individuals (Pleptin levels were significantly lower compared to healthy individuals. Thus, assessment of salivary leptin can be done as a non-invasive and simple method to determine the susceptibility of patients to advanced periodontitis. PMID:27536322

  16. Measurements of body protein for clinical investigation

    International Nuclear Information System (INIS)

    Body protein (nitrogen) is determined by bilaterally irradiating the body with neutrons using Pu-Be sources and measuring the resultant 10.8 MeV gamma rays from the reaction 14N(n,8) 15N. In the authors lab the whole body can be scanned or separate segments of the body can be measured independently. A nitrogen index has been developed based on body size and is used as a predictor of normal total body nitrogen (TBN). They have found that TBN, when normalized to body size in this way, provides a reliable index of protein status which cannot be accurately determined by body weight, anthropometry, or body potassium measurements. Changes in body composition with age were studied by measuring the composition of 56 healthy female volunteers aged 20-80. Measurements were made for K(40K), Ca and N. It was shown that protein and bone mineral decrease with age but that this is not reflected in K or anthropometry measurements. Results of other studies to be presented include: body protein measurements pre and post TPN (total parenteral nutrition), nutritional status of patients on long term CAPD (continuous ambulatory peritoneal dialysis) and changes in body composition as a result of TPN in patients with small cell lung cancer receiving chemotherapy. Clinical results show that indirect measurements of body protein based on weight, potassium, or anthropometry, do not give an accurate measure of body protein. For an accurate measurement, direct measurement of body protein is necessary

    Full Text Available To investigate the correlation between postmenopausal osteoporosis (PMO and the pathogenesis of periodontitis, ovariectomized rats were generated and the experimental periodontitis was induced using a silk ligature. The inflammatory factors and bone metabolic markers were measured in the serum and periodontal tissues of ovariectomized rats using an automatic chemistry analyzer, enzyme-linked immunosorbent assays, and immunohistochemistry. The bone mineral density of whole body, pelvis, and spine was analyzed using dual-energy X-ray absorptiometry and image analysis. All data were analyzed using SPSS 13.0 statistical software. It was found that ovariectomy could upregulate the expression of interleukin- (IL-6, the receptor activator of nuclear factor-κB ligand (RANKL, and osteoprotegerin (OPG and downregulate IL-10 expression in periodontal tissues, which resulted in progressive alveolar bone loss in experimental periodontitis. This study indicates that changes of cytokines and bone turnover markers in the periodontal tissues of ovariectomized rats contribute to the damage of periodontal tissues.

    Systemic antibiotics in conjunction with scaling and root planing (SRP), can offer an additional benefit over SRP alone in the treatment of periodontitis, in terms of clinical attachment loss (CAL) and pocket depth change, and reduced risk of additional CAL loss. However, antibiotics are not innocuous drugs. Their use should be justified on the basis of a clearly established need and should not be substituted for adequate local treatment. The aim of this review is to discuss the rationale, pr...

    Full Text Available Background: Role of various etiologic factors in periodontal disease has been investigated by means of epidemiologic surveys and clinical studies. The community periodontal index of treatment needs (CPITN provides a picture of the public health requirements in the periodontal field, which is essential for national oral health policy-making and specific interventions. Materials and Methods: This study was conducted on 4000 individuals among rural, semi-urban, and metro population of Gurgaon District, Haryana State, to find out the oral health status and periodontal treatment needs (TNs using CPITN index. Results: An inference was drawn from the results that among 4000 participants from all the four population groups' maximum, i.e., 63.80% of individuals needed TN2 whereas 18.20% of individuals needed TN3 and 18.10% of individuals needed TN1. Conclusion: It can be concluded with a word of hope and a word of warning. Hope lies in the fact that the measurement of periodontal diseases by epidemiological study of this condition is improving and receiving wide spread attention. The warning lies in the varied nature of the condition which goes to make up periodontal disease and perplexing ways in which these conditions blend. In addition to dental practitioner, periodontist and public health workers must devote more time and effort toward controlling periodontal disease than they seem to be devoting at present.

    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.

    Full Text Available Periodontitis is the result of complex interrelationships between infectious agents and host factors. Environmental, acquired, and genetic risk factors modify the expression of disease and may, therefore, affect the onset or progression of periodontitis. 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 present review is to consider the association between smoking and periodontal diseases.

    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.

    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.

    Recently in our clinic, we have seen an increased number of patients presenting with pacemakers and defibrillators. Precautions are taken to develop a treatment plan that minimizes the dose to the pacemaker because of the adverse effects of radiation on the electronics. Here we analyze different dosimeters to determine which is the most accurate in measuring pacemaker or defibrillator dose while at the same time not requiring a significant investment in time to maintain an efficient workflow in the clinic. The dosimeters analyzed here were ion chambers, diodes, metal-oxide-semiconductor field effect transistor (MOSFETs), and optically stimulated luminescence (OSL) dosimeters. A simple phantom was used to quantify the angular and energy dependence of each dosimeter. Next, 8 patients plans were delivered to a Rando phantom with all the dosimeters located where the pacemaker would be, and the measurements were compared with the predicted dose. A cone beam computed tomography (CBCT) image was obtained to determine the dosimeter response in the kilovoltage energy range. In terms of the angular and energy dependence of the dosimeters, the ion chamber and diode were the most stable. For the clinical cases, all the dosimeters match relatively well with the predicted dose, although the ideal dosimeter to use is case dependent. The dosimeters, especially the MOSFETS, tend to be less accurate for the plans, with many lateral beams. Because of their efficiency, we recommend using a MOSFET or a diode to measure the dose. If a discrepancy is observed between the measured and expected dose (especially when the pacemaker to field edge is <10 cm), we recommend analyzing the treatment plan to see whether there are many lateral beams. Follow-up with another dosimeter rather than repeating multiple times with the same type of dosimeter. All dosimeters should be placed after the CBCT has been acquired.

    Diabetes mellitus and periodontitis are both common, chronic diseases. It is generally accepted that the inter-relationship between diabetes mellitus and periodontitis is a two-way relationship, i.e. the presence of one condition tends to increases the risk and severity of the other, and vice versa. Mechanisms for this two-way relationship are largely unknown. Hyperlipidemia is a group of disorders characterized by an excess of lipids in the bloodstream. Hyperlipidemia increases the risk of diabetes and peridontitis. On the other hand, diabetes and periodontitis could result in hyperlipidemia. The purposes of this review were: (1) examine the two-way relationship between diabetes mellitus and periodontitis; (2) discuss the potential synergistic interactions of hyperlipidemia to both diabetes mellitus and periodontitis; and (3) explore the mechanisms through which hyperlipidemia affects the development of both diseases. The effects of hyperlipidemia on insulin secretion and pro-inflammatory cytokines production (TNF-α, IL-1β) play an important role on the pathogenesis of diabetes and periodontitis. A model is proposed suggesting the important role of hyperlipidemia in the two-way relationship between diabetes and periodontitis. As our understanding of the inter-relationship expands between hyperlipidemia, diabetes, and periodontitis, therapeutic strategies aimed at limiting hyperlipidemia should be advocated for the clinical management of diabetes and periodontitis.

    The adoption of new technologies for the treatment of periodontitis and the replacement of teeth has changed the delivery of periodontal care. The objective of this review was to conduct an economic analysis of a mature periodontal service market with a well-developed workforce, including general dentists, dental hygienists and periodontists. Publicly available information about the delivery of periodontal care in the USA was used. A strong trend toward increased utilization of nonsurgical therapy and decreased utilization of surgical periodontal therapy was observed. Although periodontal surgery remained the domain of periodontists, general dentists had taken over most of the nonsurgical periodontal care. The decline in surgical periodontal therapy was associated with an increased utilization of implant-supported prosthesis. Approximately equal numbers of implants were surgically placed by periodontists, oral and maxillofacial surgeons, and general dentists. Porter's framework of the forces driving industry competition was used to analyze the role of patients, dental insurances, general dentists, competitors, entrants, substitutes and suppliers in the periodontal service market. Estimates of out-of-pocket payments of self-pay and insured patients, reimbursement by dental insurances and providers' earnings for various periodontal procedures and alternative treatments were calculated. Economic incentives for providers may explain some of the observed shifts in the periodontal service market. Given the inherent uncertainty about treatment outcomes in dentistry, which makes clinical judgment critical, providers may yield to economic incentives without jeopardizing their ethical standards and professional norms. Although the economic analysis pertains to the USA, some considerations may also apply to other periodontal service markets.

    Full Text Available Nitric oxide (NO is not only important in host defense and homeostasis but it is also regarded as harmful and has been implicated in the pathogenesis of a wide variety of inflammatory and autoimmune diseases. The presence of NO in periodontal disease may reflect the participation of an additional mediator of bone resorption responsible for disease progression. The aim of this study was to assess the level of NO in serum in chronic periodontitis, and correlate these levels with the severity of periodontal disease. Sixty subjects participated in the study and were divided into two groups. NO levels were assayed by measuring the accumulation of stable oxidative metabolite, nitrite with Griess reaction. Results showed subjects with periodontitis had significantly high nitrite in serum than healthy subjects. NO production is increased in periodontal disease, this will enable us to understand its role in disease progression and selective inhibition of NO may be of therapeutic utility in limiting the progression of periodontitis.

    Full Text Available Background : Infection with human immunodeficiency virus (HIV results in loss of immunologic functions, especially those coordinated by CD4+ T-helper cells and consequent impairment of immune response. Periodontal disease has been associated with HIV infection, and HIV infection has been considered a modifier of periodontal disease. Aim: The aim of this study was to report the severity of periodontal disease in HIV-positive individuals and its association between clinical periodontal indices and CD4+T-cell count. Materials and Methods: 25 HIV-positive individuals were recruited and medical history was recorded. To evaluate periodontal disease, clinical attachment loss (CAL, oral hygiene index (OHI, and gingival bleeding index (GI were recorded. Immune suppression was measured by peripheral blood CD4+T cells/mm 3 as analyzed by flow cytometry. Statistical Analysis: Association between CD4+ T levels and clinical parameters were determined using correlation coefficient test. Results: When all subjects were evaluated, a negative correlation was obtained between CD4+ T-cell count and clinical attachment loss (r = -0.68226. In individuals with CD4+cell counts <200 cells/ mm 3 , a negative correlation was obtained between clinical attachment loss (-0.35467 and GI (-0.35202. In patients with CD4 count <200, a negative correlation was obtained between CAL (-0.30361, GI (-0.29711, and OHI (-0.14669. Conclusion: Immune suppression in combination with risk factors may increase progression of periodontal disease. Hence, these individuals should practice better oral hygiene and regular follow-up.

    Clinicians commonly use the anterior draw test (ligament laxity) and distal fibular position (lateral malleolus displacement), to measure ankle instability. The purpose of this study was to establish intra-rater and inter-rater reliability for the anterior draw test and distal fibular position in a clinical setting. The anterior draw test (AD) was measured with a plastic Goniometer, and was defined as the linear displacement of the foot as it is drawn anteriorly with the ankle held in 20 degrees of plantar-flexion. Distal fibular position (DFP) was measured in standing using a digital vernier caliper and was the relative linear distance between the lateral and the medial malleoli. 20 participants aged 21-28 volunteered for the study and were measured on both ankles. It was found that Intra-tester reliability (ICC) ranged from 0.88 to 0.97 for AD and DFP; while inter-tester reliability (ICC) was 0.6 for AD and 0.77 for DFP. In addition for measures across trials, the standard error of the measurement (SEM) was, on average 0.66 mm for AD and 1.7 mm for DFP. While the limits of agreement (LOA) was ±0.17 mm for AD and ±4.03 mm for DFP. However, the SEM and LOA between testers was 2.27 mm and ±2.27 mm respectively for AD; and for 3.1 mm and ±10.4 mm for DFP. Overall the results suggest that both measures, as defined in this study exhibit moderate to good reliability and low standard error of measurement, suggesting a high degree of repeatability across trials.

    Full Text Available Background: We face various problems while measuring the Clinical attachment level (CAL from Cemento-enamel junction (CEJ. This study aims to record and compare the CEJ location measurements using a xed reference point (FRP [Custom made stent] before and after ap elevation. Materials and Methods: A custom made stent and UNC-15 probe were used. Recording of CEJ location was made using a UNC-15 (Hu-Friedy probe, before (close CEJ and after (Open CEJ the reflection of the flap from the lower edge of the stent in those subjects who were indicated for flap surgery, at baseline. Results: We used statistical analysis involving intra-group comparison done by Paired-′t′ test. The close and the open CEJ measurements demonstrated a, statistically, non-significant difference. The equi-measurements of close and open CEJ numerical data were remarkably lower than the under and overestimation of measurements. Thus, despite certain disadvantages of stent, the FRP provides a simple solution for CAL measurement. Conclusion: The results of this study confirms the objective of the study and strongly suggests that CAL measurements done without FRP is subjected to great variation and the diagnostic and prognostic interpretation of CAL should be viewed seriously in periodontics.

    2016-01-01

    Background: Atherosclerosis is the most common cause for heart attack and stroke. In the last decade, several epidemiological studies have found an association between periodontal infection and atherosclerosis. The aim of this research was to determine the possible association between chronic periodontal disease and severity of atherosclerosis. Materials and Methods: Eighty-two subjects that were referred to Chamran Heart Hospital in Isfahan for angiography were involved in this study. Fifty-nine subjects had coronary artery obstruction (CAO) and 23 showed no obstruction after angiography. The severity of CAO was assessed. Periodontal parameters including pocket depth (PD), gingival recession (R), clinical attachment level (CAL), and bleeding on probing (BOP) of all subjects were recorded. The decayed-missing-filled (DMF) index of all subjects was also measured. For statistical analysis, Pearson correlation test, Chi-square, and independent t-test were used. Results: There were significant positive correlation between variables R, PD, CAL, decayed (D), missing (M), DMF, BOP, and degree of CAO. However, there were no significant differences between filling variable degree of CAO (left anterior descending, left circumflex, and right coronary artery). Independent t-test showed that the mean of variables R, PD, AL, D, M, and DMF in patients with obstructed arteries were significantly higher than subjects without CAO. But there were no significant differences between variable F in two groups. Conclusion: The results of this cross-section analytical study showed an association between periodontal disease and dental parameters with the severity of CAO measured by angiography. However, this association must not interpret as a cause and effect relationship. PMID:27274346

    Objective: The aims of this descriptive, cross-sectional investigation were to evaluate the gingival health awareness of dental students by comparing their clinical gingival bleeding scores and self-reports, and to compare differences in awareness between males and females. Methods: In total, 100 (51 males, 49 females) freshman dental students were included in the study. Periodontal indices recorded were: Presence of plaque percentage (plaque index [PI], %), percentage of sites of bleeding on probing (BOP, %), probing depth, and community periodontal index (CPI). Percent agreement, kappa agreement, sensitivity, and specificity were calculated by comparing their self-reported gingival bleeding and BOP%. Results: The self-reports of gingival bleeding exhibited statistically significant correlations with BOP% in females (r = 0.42, P = 0.003). Female students showed a higher degree of awareness when kappa agreement, 0.23 (males: 0.16, females: 0.39), sensitivity, 48% (males: 42%, females: 51%), and specificity, 95% (males: 90%, females: 100%) were calculated. Although male dental students had higher PI and CPI scores, there was no significant difference by gender in the clinical measurements. Conclusions: According to our results, the validity of self-reported gingival bleeding was higher among dental students than in previous population-based studies. Female dental students showed a higher degree of awareness than males of their gingival health. Half of the included dental students could not differentiate whether they had gingival bleeding when there was actual bleeding. More emphasis should be given to the education of dental students regarding the relationship between gingival bleeding and active periodontal disease. PMID:25202217

    Full Text Available Epidermal growth factor (EGF is a polypeptide molecule, with important functions in epithelial growth and wound repair. It exerts its effects on cells by binding to receptors on the cell surface. The aim of this study was to evaluate and compare salivary EGF levels in patients with gingivitis and advanced periodontitis as well as in healthy controls.Unstimulated salivary samples were collected from patients with gingivitis and advanced periodontitis and healthy individuals. The clinical parameters of plaque index (PI, bleeding on probing (BOP, probing pocket depth (PPD and clinical attachment level (CAL were measured and recorded using a Williams probe. The enzyme-linked immunosorbent assay (ELISA was used to determine salivary levels of EGF. One-way ANOVA was used for data analysis.The mean salivary level of EGF in healthy individuals (99.27 was significantly higher than that in patients with gingivitis (61.53. This value in patients with gingivitis (61.53 was also significantly higher than that in subjects with periodontitis (36.14 (P<0.001.The reduction in salivary level of EGF in patients with periodontal disease may be related to the pathogenesis of periodontitis.

    Study of the histological characteristics of the teeth, dental rudiments, and periodontal tissues of animals during distraction of the maxilla and distal dislocation of the mandible by "minor", "medium", and "strong" force showed that the type and degree of morphological changes are related to the strength of exposure and duration of orthodontist device application. The minor (1.2 H) and medium (2.5 H) force did not injure the studied structural elements of the periodical complex. Exposure of osseous tissues to a strong (5.0 H) force surpassing the compensatory potential of this tissue caused a complex of changes characterized by predominance of the processes of destruction of bone matter, specifically, by its resorption over its regeneration. These processes were the most evident during distal dislocation of the mandible. Appreciable foci of resorption were observed not only in the alveolar process bone, but in hard tissues (dentin and cement) of deciduous teeth as well. These results demonstrate the necessity of a careful approach to the choice of the intensity of force developed by various orthodontist devices.

    Full Text Available New research is demonstrating that a person’s total health is indeed related to their oral health. Elimination of all oral infectio ns, including gingivitis and periodontitis, is important to overall health. The article reviews va rious trends in nonsurgical and surgical therapy that will successfully arrest periodontal inf ections. Opportunities for early diagnosis and prevention will play an increasing role in dental practice in the future as patients understand the importance of oral health to overall health. There is an urgent need to educate the public as to the importance of periodontal health . All of these findings indicate that periodontal disease must be viewed from a whole new perspective, particularly since some form of periodontal disease is present in a large per centage of the population. A prospective approach of prevention and early intervention in trea ting the disease is more important than ever before.

  20. Nicotine and periodontal tissues

    Malhotra Ranjan

    2010-01-01

    Full Text Available Tobacco use has been recognized to be a significant risk factor for the development and progression of periodontal disease. Its use is associated with increased pocket depths, loss of periodontal attachment, alveolar bone and a higher rate of tooth loss. Nicotine, a major component and most pharmacologically active agent in tobacco is likely to be a significant contributing factor for the exacerbation of periodontal diseases. Available literature suggests that nicotine affects gingival blood flow, cytokine production, neutrophil and other immune cell function; connective tissue turnover, which can be the possible mechanisms responsible for overall effects of tobacco on periodontal tissues. Inclusion of tobacco cessation as a part of periodontal therapy encourages dental professionals to become more active in tobacco cessation counseling. This will have far reaching positive effects on our patients′ oral and general health.

    Full Text Available Aim. The present cohort study describes the longitudinal relationship between plasma oxidative status and periodontitis progression during the maintenance phase of treatment. Materials and Methods. Forty-five patients (mean age 58.8 years were monitored from 2008 to 2013. Periodontal conditions, including probing pocket depth (PPD and clinical attachment level (CAL, were recorded. Measurements of plasma reactive oxygen metabolites (ROM and biologic antioxidant potential (BAP were performed to evaluate plasma oxidative status. The patients were assigned into 2 groups as low and high plasma ROM level using a cut-off value which was median of plasma ROM level at baseline. Results. In the subjects with low plasma ROM level at baseline, changes in mean CAL were positively correlated with changes in plasma ROM levels, bleeding on probing, and plaque control record, but not with PPD. In the subjects with high plasma ROM at baseline, changes in CAL were significantly associated with only PPD at baseline. On the other hands there were no significant associations between changes in CAL and those in plasma BAP levels. Conclusions. When plasma ROM level in periodontitis patients was low, increases in plasma ROM level were associated with those in CAL during the maintenance phase of treatment.

    Full Text Available Objectives. This study was undertaken to investigate the OPG profiles in gingival crevicular fluid (GCF, saliva, and gingival tissues of chronic periodontitis (CP patients in response to open flap debridement (OFD. Subjects and Methods. The study included 30 subjects divided into 2 groups: 20 CP patients and 10 periodontally healthy subjects. Plaque index, gingival index, pocket depth, and clinical attachment level measurements were recorded for all subjects. GCF, salivary, and gingival samples were collected from all 30 subjects at baseline and 3 and 6 month after OFD from the 20 CP patients. GCF and salivary OPG levels were assessed by ELISA assay, while OPG expression in gingival tissues was examined by immunohistochemistry. Results. GCF, salivary and gingival OPG profiles were significantly higher in control subjects compared to CP patients at baseline (P<0.001. Within CP group, OPG levels in GCF, saliva, and gingival samples showed a significant increase at 3 and 6 months after OFD (P<0.001 compared to baseline. Although OPG values increased significantly in gingival samples and insignificantly in saliva after 3 months compared to 6 months, yet GCF levels were significantly decreased. Conclusions. OPG might be considered as a diagnostic and prognostic biomarker of periodontal bone destruction. This trial is registered with NCT02160613.

    2012-01-01

    Full Text Available Context: Clinical evaluation of gingivitis and/or periodontitis does not predict the progression or remission of the disease. Due to this diagnostic constraint, clinicians assume that the pathology has an increased risk of progression and plan treatments, despite the knowledge that all inflamed sites are not necessarily progressing. Extensive research has been carried out on gingival crevicular fluid (GCF components that might serve as potential diagnostic markers for periodontitis. Among them alkaline phosphatase (ALP levels in GCF has shown promise as a diagnostic marker. Aim: This study compares the levels of GCF alkaline phosphatase in patients with chronic periodontitis before and after scaling and root planing. Materials and Methods: This study is an in vivo longitudinal study conducted on twenty patients with localized periodontitis. The GCF was collected from the affected site prior to scaling and root planing and ALP level estimated. The probing depth and plaque index at the site were also measured for correlation. Patients were recalled after 7, 30, and 60 days for reassessment. Results: The GCF ALP values showed a sustained, statistically significant decrease after treatment. There was a positive correlation with probing depth but not with plaque index measured at each interval. Conclusion: The assessment of level of periodontal disease and effect of mechanical plaque control on the progression and regression of the disease can be evaluated precisely by the corresponding GCF ALP levels. Thus, alkaline phosphatase level is not only a biomarker for the pathology but also an indicator of prognosis of periodontitis.

    Full Text Available Statement of Problem: Periodontitis is a chronic multi-factorial infectious disease,characterized by irreversible destruction of collagen fibers and other matrix constituents of the gingival tissues, periodontal ligament and resorption of the alveolar bone around the teeth with formation of periodontal pocket. Cytokines such as IL-1β are one of the components of host’s immune system and seem to play an important role in periodontitisPurpose: The aim of this study was to determine the concentration of IL-1β as a per-inflammatory cytokine in the saliva of periodontally involved patients (generalized aggressive periodontitis and mild to moderate periodontitis and subjects with normal periodontium.Materials and Method: In this experimental study, unstimulated saliva of 24 patients with mild to moderate chronic periodontitis, 15 patients with aggressive periodontitis, and 23 subjects with healthy periodontium was collected. The concentration of IL-1β was measured in the saliva samples by ELISA. Mann-Whitney test was used for analysis of data.Results: The results of this study showed that there was a significant difference between mean level of IL-1ß in generalized aggressive periodontitis vs. control groups and chronic mild to moderate periodontitis vs. control groups ( p <0.05. Conclusion: The findings of the present study showed that the mean concentration of IL-1ß in the saliva of periodontally involved patients was greater than that of healthy subjects and this cytokine can be agood marker for determining the status of periodontal tissues.

  9. MR-Imaging of teeth and periodontal apparatus: an experimental study comparing high-resolution MRI with MDCT and CBCT

    International Nuclear Information System (INIS)

    The aim of this study was (1) to assess the ability of magnetic resonance imaging (MRI) to visualize dental and periodontal structures and (2) to compare findings with multidetector computed tomography (MDCT) and cone beam CT (CBCT). Four porcine mandibles were examined with (1) 3T-MRI, (2) MDCT and (3) CBCT. Two observers independently reviewed MR, MDCT and CBCT images and assessed image quality of different dental and periodontal structures. To assess quantitatively the accuracy of the different imaging technique, both observers measured burr holes, previously drilled in the mandibles. Dental structures, e.g. teeth roots, pulpa chamber and dentin, were imaged accurately with all imaging sources. Periodontal space and cortical/trabecular bone were better visualized by MRI (p < 0.001). MRI could excellently display the lamina dura, not detectable with MDCT and only inconstant visible with CBCT (p < 0.001). Burr hole measurements were highly precise with all imaging techniques. This experimental study shows the diagnostic feasibility of MRI in visualization of teeth and periodontal anatomy. Detection of periodontal structures was significantly better with MRI than with MDCT or CBCT. Prospective trials have to evaluate further the potential benefit of MRI in a clinical setting. (orig.)

    Some studies suggest that periodontal diseases increase the risk of oral cancer, but contradictory results also exist. Inadequate control of confounders, including life course exposures, may have influenced prior findings. We estimate the extent to which high levels of periodontal diseases, measured by gingival inflammation and recession, are associated with oral cancer risk using a comprehensive subset of potential confounders and applying a stringent adjustment approach. In a hospital-based case-control study, incident oral cancer cases (N = 350) were recruited from two major referral hospitals in Kerala, South India, from 2008 to 2012. Controls (N = 371), frequency-matched by age and sex, were recruited from clinics at the same hospitals. Structured interviews collected information on several domains of exposure via a detailed life course questionnaire. Periodontal diseases, as measured by gingival inflammation and gingival recession, were evaluated visually by qualified dentists following a detailed protocol. The relationship between periodontal diseases and oral cancer risk was assessed by unconditional logistic regression using a stringent empirical selection of potential confounders corresponding to a 1% change-in-estimates. Generalized gingival recession was significantly associated with oral cancer risk (Odds Ratio = 1.83, 95% Confidence Interval: 1.10-3.04). No significant association was observed between gingival inflammation and oral cancer. Our findings support the hypothesis that high levels of periodontal diseases increase the risk of oral cancer.

    ", "periodontitis", "carotid", and "therosclerosis". Articles were excluded if they: presented abstracts written in languages other than Portuguese, English and Spanish; experimental studies; did not contain data testing the degree of association between periodontal disease and subclinical atherosclerosis; did measure the extent of periodontal disease by parameters other than the clinical examination; did not measure the carotid artery intima-media wall thickness by ultrasonography; and covered specific population groups. The studies design, measurement protocols and reported data were compared. A total of 63 papers identified only 10 studies that met the inclusion criteria: 1 longitudinal study, 6 cross-sectional, and 3 case control studies. There was a wide heterogeneity between the studies regarding the methods of measuring periodontal disease and atherosclerosis outcomes. The conclusion is that periodontal infections are strongly associated with the development of subclinical atherosclerosis, however the mechanisms involved on the pathogenic process remain unknown.

    Full Text Available Aims: Periodontal disease has been considered a systemic exposure implicated in a higher risk of adverse pregnancy outcomes. The aim of the present study was to determine whether maternal oral health is associated with an increased risk of pre-eclampsia. Subjects and Methods: A case-control study was conducted which included 40 pregnant women patients admitted to the Department of Obstetrics and Gynecology, J.N. Medical College, A.M.U, Aligarh. Pre-eclampsia was defined as classic triad of hypertension, proteinuria and symptoms such as swelling/edema esp. in hands and face, headache, visual changes etc., A periodontal examination was done during 48 h after child delivery. Maternal oral status was evaluated using gingival index by Loe and Silness, oral hygiene index (simplified by greene and vermillion and periodontal pockets and clinical attachment level (CAL. Statistical Analysis: Null hypothesis that no difference exist between the two groups (pre-eclamptic and non-pre-eclamptic Group was calculated using paired t-test, Chi-square and Mann-Whitney U statistical tests using SPSS 11.5 (Statistical Package for Social sciences, Chicago. P < 0.05 was considered to be statistically significant. Results: The amount of gingival inflammation, oral hygiene levels, pocket depth and CALs as measured by their respective indices were higher in the pre-eclamptic group when compared to non-pre-eclamptic group. Furthermore CAL was significantly increased in the test group. This study showed that pre-eclamptic cases were more likely to develop periodontal disease (P < 0.05. 30% of the test group and 65% of the case group had periodontal disease (P < 0.05 which had shown that pre-eclamptic cases were 4.33 times more likely to have periodontal disease (odds ratio = 4.33. Conclusions: Maternal oral status was determined to be associated with an increased risk of pre-eclampsia.

    Periodontal diseases are frequently associated with cardiovascular diseases (CVD). On the other hand, occurrence of CVD has also been related with increased blood viscosity. This study was planned to investigate four main hemorheological parameters contributing to blood viscosity - hematocrit, erythrocyte deformability, erythrocyte aggregation and plasma viscosity - and also some biochemical parameters (hs-CRP, fibrinogen, globulin etc.) in patients with periodontal disease. We hypothesized that poor periodontal health would be associated with deterioration of hemorheological properties. According to periodontal health status, subjects were divided into three groups as control (healthy), with plaque induced gingivitis and with chronic periodontitis. All groups included 15 males who had not received periodontal therapy in the last six months before the study, were non-smokers, had no systemic diseases and were not on any medication. Erythrocyte deformability and erythrocyte aggregation were measured with laser-assisted optical rotational cell analyzer (LORCA). Plasma viscosity was measured by a cone-plate viscometer. Data were analyzed with Kruskal-Wallis, Mann-Whitney U Test and Spearman Correlation Coefficient. Plasma viscosity (1.36 ± 0.01 mPa.s in the control group and 1.43 ± 0.02 mPa.s in the chronic periodontitis group, P <  0.01), erythrocyte aggregation tendency (aggregation index, amplitude and t½ were 58.82 ± 1.78% , 20.22 ± 0.40 au, 2.80 ± 0.25 s respectively in the control group, and 67.05 ± 1.47% , 22.19 ± 0.50 au, 1.84 ± 0.15 s in the chronic periodontitis group, P <  0.01), hs-CRP, fibrinogen and globulin levels were significantly higher, whereas HDL level was significantly lower in the chronic periodontitis group (P <  0.05) compared to the control group. All of these conditions may contribute to cardiovascular morbidity and mortality observed in people with periodontal disease, via increasing blood viscosity. PMID:25261434

    Full Text Available Aggressive periodontitis is characterized by non-contributory medical history, rapid attachment loss and bone destruction and familial aggregation of cases. Aggressive periodontitis (both localized and generalized is usually diagnosed in a young population. This is frequently the age that an orthodontic care is provided to this population. The aim of the present paper is to draw guidelines for periodontal evaluation and monitoring prior to and during active orthodontic treatment. Strict adherence to these guidelines as a routine protocol for periodontal examination prior, during and following orthodontic treatment may dramatically decrease the severity and improve the prognosis of patients with aggressive periodontitis in orthodontic clinics.

  16. Smoking as a permissive factor of periodontal disease in psoriasis.

    Directory of Open Access Journals (Sweden)

    Márk Antal

    Full Text Available BACKGROUND: Population-based studies have identified smoking as a pathogenetic factor in chronic periodontitis. At the same time, chronic periodontal disease has also been found to occur more often in persons suffering from psoriasis than in controls with no psoriasis. It is known that smoking aggravates both periodontal disease and psoriasis, but so far it has not been investigated how smoking influences the occurrence and severity of periodontal disease in psoriasis. METHODS: A hospital-based study was conducted to investigate this question. The study population consisted of 82 psoriasis patients and 89 controls. All patients received a full-mouth periodontal examination, and a published classification based on bleeding on probing, clinical attachment level and probing depth was utilized for staging. Both patients and controls were divided into smoker and non-smoker groups, and the resulting groups were compared in terms of periodontal status. Beyond the descriptive statistics, odds ratios were computed. RESULTS: Psoriasis in itself increased the likelihood of severe periodontal disease to 4.373 (OR, as compared to non-smoker controls, p<0.05, while smoking increased it to 24.278 (OR, as compared to non-smoker controls, p<0.001 in the studied population. In other words, the risk of severe periodontal disease in psoriasis turned out to be six times higher in smokers than in non-smokers. CONCLUSIONS: The results of this study corroborate those of other studies regarding the link between psoriasis and periodontal disease, but they also seem to reveal a powerful detrimental effect of smoking on the periodontal health of psoriasis patients, whereby the authors propose that smoking may have a permissive effect on the development of severe periodontal disease in psoriasis.

    Full Text Available Context Oral cavity is one of the most common sites for neoplasms with a multifactorial etiology. Tobacco and alcohol are the main risk factors. Periodontal disease is an inflammatory disease affecting periodontal tissues such as gingiva, periodontal ligament and alveolar bone. Periodontal disease is linked to many systemic diseases. Recently a link between periodontal disease and cancer is suggested. The current review article aimed to evaluate the association between periodontal disease and risk of cancer in the oral cavity and some related factors. Evidence Acquisition Evidence suggests that oral cavity cancer is significantly more prevalent in patients with periodontal disease, poor oral hygiene or more missing teeth. Clinically, gingival squamous cell carcinoma (GSCC usually appears as an exophytic mass with a granular, papillary or verrucous surface or presents as an ulcerative lesion. Some reported cases of GSCC mimicking periodontal disease include gingival enlargement with no bone invasion, dentoalveolar abscess, erosive erythematosus lesion with keratotic papules, root exposure and tooth mobility, verrucous leukoplakia, verruciform xanthoma and development of hyperplastic granulation tissue after tooth extraction. Greater burden of oral flora that produce carcinogenic metabolites, human papilloma virus (HPV and other viruses that are residents of periodontal pocket, increased amount of inflammatory mediators and markers and some periodontal pathogens affecting cell cycle leading to mutation and dysplasia are considered as the rational for the relationship between malignant lesions of oral cavity and periodontal disease. Results Cancer of the oral cavity and periodontal disease are related from different aspects. Periodontal disease and tooth loss are considered as independent risk factors for cancer. Gingival squamous cell carcinoma can also mimic periodontal disease leading to misdiagnosis and delayed commencement of appropriate

    Full Text Available The use of anti-platelet therapy has reduced the mortality and morbidity of cardiovascular disease remarkably. A considerable number of patients presenting before a dentist or periodontist give a history of anti-platelet therapy. A clinical dilemma whether to discontinue the anti-platelet therapy or continue the same always confronts the practitioner. Diverse opinions exist regarding the management of such patients. While one group of researchers advise continuation of anti-platelet therapy rather than invite remote, but possible, thromboembolic events, another group encourages discontinuation for variable periods. This study aims at reviewing the current rationale of anti-platelet therapy and the various options available to a clinician, with regard to the management of a patient under anti-platelet therapy. Current recommendations and consensus favour no discontinuation of anti-platelet therapy. This recommendation, however, comes with a rider to use caution and consider other mitigating factors as well. With a large number of patients giving a history of anti-platelet therapy, the topic is of interest and helps a clinician to arrive at a decision.

    Full Text Available Cystatin C (CSTC is an inhibitor of cysteine proteinases and could play a protective and regulatory role under inflammatory conditions. The present study was designed to assess the concentration of CSTC in gingival crevicular fluid (GCF and serum, to find out their association if any, in periodontal health and disease. 30 subjects were selected divided into 3 groups consisting of 10 subjects in each group based on clinical parameters: periodontally healthy group, gingivitis group and chronic periodontitis group, while, chronic periodontitis group after 8 weeks of the treatment (scaling and root planing constituted after periodontal therapy group. GCF and serum samples were collected from all subjects to estimate the levels of CSTC by ELISA. The mean CSTC concentration in GCF and serum was observed to be the highest in periodontitis group and lowest in periodontally healthy group with intermediate concentration in gingivitis group and after periodontal therapy group. CSTC concentration in GCF and serum increased proportionally with the severity of periodontal disease (from health to periodontitis group and decreased after treatment. This suggests that CSTC increases with disease progression to prevent further periodontal degeneration and decreases after treatment due to bone metabolic homeostasis. Further, longitudinal prospective studies involving larger population are needed to confirm the findings of present study and to better understand the role of CSTC in the pathogenesis of periodontal diseases.

    Objetive: Fibromyalgia (FM) is a chronic pain syndrome with unknown etiology, which affects predominantly women. Mitochondrial alteration could have a role in the pathophysilogical mechanisms of inflammatory conditions as FM and periodontitis. The aim of the present study was assay the relationship between both diseases and mitochondrial dysfunction. Patient and Methods: We study the presence of periodontitis in twelve patients diagnosed of FM and mitochondrial dysfunction described. The diagnosis of FM was established according to ACR criteria and clinical symptoms were evaluated using the Fibromyalgia Impact Questionnaire (FIQ) and Beck Depression Inventory (BDI). Results: Only one patients of twelve included and agreed to participate in the study were diagnosed with periodontitis. Conclusions: Pending studies with larger numbers of patients, we can conclude that mitochondrial dysfunction in FM is a itself event not related with periodontitis. Periodontitis could be considered a exclusion criterion in all studies about mitochondrial dysfunction in patients. Key words:Peridontitis, fibromyalgia, mitocondrial dysfunction, oxidative stress.

    Full Text Available Background: Human periodontal diseases are inflammatory disorders as the result of complex interactions between periodontopathogens and the host’s immune response. Periodontitis results in tooth loss and can even lead to systemic diseases if not treated. Gingival crevicular fluid (GCF reflects the condition of the gingiva and contains proteins transuded from serum or cells at inflamated sites. Polymorphonuclear leukocyte (PMNs infiltration can be seen in each stage of periodontitis. Lactoferrin is one of the PMN specific granules and could be a useful marker of PMN activity. Purpose: The aim of this study was to determine the band intensity of lactoferrin used as periodontitis biomarker. Methods: Gingival crevicular fluid (GCF samples were collected using paper point no.30 from 40 subjects, 30 periodontitis patients that devide according to the severity (10 mild periodontitis, 10 moderate periodontitis, and 10 severe periodontitis and 10 healthy controls, ranging in ages from 20 to 35 years. GCF lactoferrin was analyzed by Western blot and measured the band intensity by quantity one software (bio-rad. Results: The periodontitis sites exhibited significantly greater band intensity of lactoferrin than healthy sites. The band intensity of lactoferrin was positively correlated with the severity of periodontitis (α = 0.05. Conclusion: The study showed that the intensity of the lactoferrin protein bands could be used as biomarkers of periodontitis.Latar belakang: Penyakit periodontal adalah gangguan inflamasi yang merupakan hasil dari interaksi yang kompleks antara periodontopathogens dan respon imun host.

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.)

    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. PMID:26150714

    Full Text Available Hyaluronic acid is a naturally occurring linear polysaccharide of the extracellular matrix of connective tissue, synovial fluid, and other tissues. Its use in the treatment of the inflammatory process is established in medical areas such as orthopedics, dermatology, and ophthalmology. The Pubmed/Medline database was searched for keywords "Hyaluronic acid and periodontal disease" and "Hyaluronic acid and gingivitis" which resulted in 89 and 22 articles respectively. Only highly relevant articles from electronic and manual search in English literature were selected for the present review article. In the field of dentistry, hyaluronic acid has shown anti-inflammatory and anti-bacterial effects in the treatment of periodontal diseases. Due to its tissue healing properties, it could be used as an adjunct to mechanical therapy in the treatment of periodontitis. Further studies are required to determine the clinical efficacy of hyaluronic acid in healing of periodontal lesion. The aim of the present review, article is to discuss the role of hyaluronic acid in periodontal therapy.

    Full Text Available Background: In the recent years, various studies have shown a link between the free radicals, antioxidants and periodontal diseases. The purpose of the present study was to evaluate the oxidative stress and the antioxidant status present in the gingival tissue and plasma of patients with chronic periodontitis and to evaluate the antioxidant property of taurine. Materials and Methods: Periodontal status in 10 chronic periodontitis patients was assessed in terms of gingival index, plaque index, probing pocket depth and clinical attachment level prior to and after oral administration of taurine (500 mg O.D. for 15 days. The oxidative stress present in the gingival tissue and blood (by measuring thiobarbituric acid reactive substance [TBARS] and the antioxidants namely glutathione peroxidase (GPX and reduced glutathione (GSH were estimated before and after administration of taurine. The changes in the clinical parameters were also reassessed following administration of taurine. Statistical comparisons were performed using the Student′s t-test. A level of P < 0.05 was considered as statistically significant. Results: The levels of TBARS in plasma and gingival tissue showed a significant reduction (P < 0.001 following administration of taurine. The antioxidant enzyme GPX showed a significant reduction following administration of taurine (P < 0.001, whereas GSH increased significantly (P < 0.001 following administration of taurine. The improvement in the periodontal status following administration of taurine was also significant statistically. Conclusion: Based on the biochemical and clinical assessments, taurine seems to exert a protective role against the oxidative stress in the management of patients with chronic periodontitis.

    Full Text Available Systemic antibiotics in conjunction with scaling and root planing (SRP, can offer an additional benefit over SRP alone in the treatment of periodontitis, in terms of clinical attachment loss (CAL and pocket depth change, and reduced risk of additional CAL loss. However, antibiotics are not innocuous drugs. Their use should be justified on the basis of a clearly established need and should not be substituted for adequate local treatment. The aim of this review is to discuss the rationale, proper selection, dosage and duration for antibiotic therapy so as to optimize the usefulness of drug therapy.

  15. Low levels of caries in aggressive periodontitis: A literature review

    2014-04-01

    Full Text Available This article is a traditional literature review on caries levels in aggressive periodontitis. Aggressive periodontitis generally affects systemically healthy individuals aged <30 years (older individuals can also be affected and is characterized by a young age of onset, rapid rate of disease progression, and familial aggregation of cases. Dental caries is caused by the dissolution of enamel by acid-producing bacteria present in the plaque biofilm, especially when the biofilm reaches critical mass due to improper oral hygiene. The association between caries level and aggressive periodontitis has long been debated. Initial research indicated that caries levels were high in patients with aggressive periodontitis, but high-quality studies have consistently shown that caries and aggressive periodontitis are inversely related. A recent in vitro study showed that Streptococcus mutans was killed more readily in the saliva of patients with aggressive periodontitis and Aggregatibacter actinomycetemcomitans positivity than in patients with A. actinomycetemcomitans negativity. Other mechanisms possibly explaining the inverse relationship between caries and aggressive periodontitis in cases of Down’s syndrome are also discussed in this literature review. The usefulness of caries level in the diagnosis of aggressive periodontitis in developing countries such as India, where the disease is diagnosed primarily on the basis of clinical and radiographic features and familial history is also discussed.

    Full Text Available Background. Periodontitis is the most common chronic inflammatory condition worldwide and is associated with incident coronary disease. Hypothesis. We hypothesized that periodontal disease would also be associated with cardiac calcification, a condition which shares many risk factors with atherosclerosis and is considered a marker of subclinical atherosclerosis. Methods. Cross-sectional study at two sites (USA and Japan involving subjects with both clinical echocardiograms and detailed dental examinations. Semiquantitative scoring systems were used to assess severity of periodontal disease and echocardiographic calcification. Results. Fifty-six of 73 subjects (77% had cardiac calcifications, and 51% had moderate to severe periodontal disease (score > 2. In unadjusted analysis, a significant relationship between periodontal score and cardiac calcification (Spearman rho = 0.4, P=0.001 was noted, with increases in mean calcification score seen across increasing levels of periodontal disease. On multivariate logistic regression, adjusted for age, gender, race, glomerular filtration rate, and traditional risk factors, this association remained significant (P=0.024. There was no significant interaction by study site, race, or gender. Conclusions. In a multiracial population, we found a significant association between the degree of periodontal disease, a chronic inflammatory condition, and cardiac calcification. Further, higher periodontal scores were associated with greater degrees of calcification.

    2012-01-01

    Full Text Available Background: In today′s world, people are very much aware about their looks and personality. They are getting more concerned about the esthetics and thus are not ready to compromise the appearance of black holes, especially in the anterior region of the mouth. Various techniques like orthodontic correction, prosthetic veneers and various periodontal surgical methods have been used to cover these unaesthetic open embrasures. In the present study, a variant technique given by Beagle in 1992 was used to cover these open gingival embrasures. The technique uses a gingival flap from the labial aspect to close the open gingival embrasures thus solving the problem of black holes. Aims and Objectives: This clinical study was aimed to reconstruct the lost or blunted interdental papillae with gingival tissue for esthetic purpose and for maintaining oral health with the objective to determine the extent to which the procedure can revert the maxillary esthetics. Materials and Methods: The patients selected were those who were having a complaint of at least one black hole in the maxillary anterior region with grade ′0′ or ′1′ type of contour of interdental tissues. A total of 39 open embrasures were surgically closed using this technique. Various indices were taken pre-surgically and then again post surgically. Results: Plaque index and gingival index showed an initial increase in the scores at the end of 1 week. Later, there was a gradual fall till the end of the study. Bleeding index significantly increased at the end of 12 weeks ( P<0.001 but reduced to insignificant levels at the end of 24 weeks ( P<0.09. The sulcus depth increased by about 1.19 mm. There was improvement in the contour of interdental tissues in 51% of cases and in 38.46% the interdental papillae completely obliterated the open embrasures. Conclusion: The surgical technique used here for reconstruction of interdental papilla was fairly successful. However, use of bone grafts or

    Full Text Available Chronic kidney disease (CKD is a debilitating systemic condition. Our working hypothesis is that CKD predialysis patients with periodontitis would respond poorly to periodontal treatment owing to immunologic compromise. Twenty-one predialysis patients (group 1 and 19 individuals without clinical evidence of kidney disease (group 2 with chronic periodontitis were subjected to non-surgical periodontal treatment with no antibiotics. Clinical periodontal and systemic parameters were evaluated at baseline and 3 months after treatment. Both groups showed significant and similar post-treatment improvements in all periodontal parameters examined. Most interestingly, periodontal treatment had a statistically significant positive effect on the glomerular filtration rate of each individual (group 1, p = 0.04; group 2, p = 0.002. Our results indicate that chronic periodontitis in predialysis kidney disease patients improved similarly in patients with chronic periodontitis and no history of CKD after receiving non-surgical periodontal therapy. This study demonstrates that CKD predialysis patients show a good response to non-surgical periodontal treatment.

  20. Periodontal disease and halitosis

    International Nuclear Information System (INIS)

    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)

    Full Text Available Background: Successful reconstruction of periodontal tissues destroyed due to periodontitis has been an evasive goal for the periodontists. Several GTR materials and bone grafts have been tried with varied success rates. Aims and Objectives: The aim of the present study was to evaluate and compare the efficacy of non-resorbable (GoreTex® and bioabsorbable (Resolut Adapt® membranes in combination with bioactive glass (PerioGlas® in the treatment of periodontal intrabony defects. Materials and Methods: Ten chronic periodontitis patients having bilateral matched intrabony defects were treated with non-resorbable membrane (GoreTex® and bioactive glass or the bioresorbable membrane (Resolut Adapt® and bioactive glass in split mouth design. Clinical parameters like plaque index, gingival index, probing pocket depth, clinical attachment level, and gingival recession were recorded at baseline and 9 months post-operatively. Similarly, radiographic (linear CADIA and intra-surgical (re-entry measurements were evaluated at baseline and 9 months post-operatively. Results: Both the membrane groups showed clinically and statistically significant improvement in clinical parameters i.e., reduction in probing depth (4.6 ± 1.4 mm vs. 3.7 ± 1.3 mm and gain in clinical attachment level (4.6 + 1.6 vs. 3.2 ± 1.5 mm for non-resorbable and bioresorbable membrane groups, respectively. Similar trend was observed when radiographical and intra-surgical (re-entry measurements were evaluated and compared, pre- and post-operatively at 9 months. However, on comparison between the two groups, the difference was statistically not significant. Conclusion: Both the barrier membranes i.e., non-resorbable (Gore-Tex® and bioabsorbable (Resolut Adapt® membranes in combination with bioactive glass (PerioGlas® were equally effective in enhancing the periodontal regeneration.

    Statement of the Problem Trichomonas tenax and Entamoeba gingivalis are commensal protozoa which inhabit the human oral cavity. These parasites are found in patients with poor oral hygiene and might be a reason for progressive periodontal diseases. Purpose The aim of this study was to evaluate the effect of nonsurgical periodontal treatment on the frequency of these protozoa in saliva and plaque samples. Materials and Method In this clinical trial, samples of saliva and dental plaque were collected from 46 patients with moderate to severe chronic periodontitis before and after periodontal therapy. The samples were assessed for the frequency of parasites. Results The frequency of Entamoeba gingivalis was reduced in saliva (p= 0.007) and plaque (p= 0.027) three weeks after the treatment. Likewise, the frequency of Trichomonas tenax reduced in saliva (p= 0.030); however, the decrease was not significant in plaque (p= 0.913). Trichomonas tenax frequency in dental plaque directly related to the severity of periodontitis (r= 0.565, p≤ 0.000). In contrast, the number of Entamoeba gingivalis in both saliva (r= -0.405, p≤ 0.005) and plaque (r= -0.304, p= 0.040) was inversely related with the severity of the periodontal disease. Conclusion Nonsurgical periodontal treatment could reduce the number of Trichomonas Tenax and Entamoeba gingivalis in the oral environment of patients with chronic periodontitis. PMID:27602391

    Full Text Available Background/Aim. Diabetes mellitus (DM as a complex metabolic disease influences functioning of numerous organs. Therefore, frequent diabetic complication is chronic periodontitis. The aim of the study was to investigate the influence of various risk factors, like age, sex, duration of DM, oral hygiene, on oral manifestations of diabetes. Methods. The group of diabetics included 52 adult patients, 18-79-year of age, both sexes (33 females, 19 males out of which 35 patients were with diabetes mellitus type I and 17 with type II. Mean age of the patients was 54.6 years and the mean duration of diabetes was 11.1 years. The controls consited of 67 volunteers from the city of Belgrade, 19-24-year of age, both sexes (47 females, 20 males with no paradonthopathy and non-systemic diseases. Estimation of periodontal status of the patients was performed by measuring dental plaque index, gingival index and periodontal pockets' depth. Results. The results suggest an increased incidence and severity of periodontitis in diabetic patients. It was established that duration of diabetes, patients' age and bad oral hygiene had a negative influence on status of remained teeth in diabetics, while the sex had no influence on parameters monitored. Conclusion. Indices of oral hygiene level and periodontal status (dental plaque index, gingival index and periodontal pockets' depth were significantly worsened in patients with diabetes. Negative influence on remained teeth had patients' age (>50 years, duration of diabetes (> 20 years and bad oral hygiene. About half of the patients had a total or partial bridge suggesting that periodontitis is significant complication of diabetes mellitus.

    Full Text Available Objective: To assess the general knowledge of Nigerian dentists on aggressive periodontitis (AgP and specific knowledge of distinguishing between the clinical features of localized aggressive periodontitis (LAP and generalized aggressive periodontitis (GAP. Materials and Methods: A cross-sectional, non-random convenience survey was done on 200 dentists, in three geopolitical zones of Nigeria, using pre-tested, closed question– type questionnaires. Eventually, only 133 questionnaires were analyzed. Relationships between six outcome variables namely clinical features of LAP, clinical features of GAP, LAP oral hygiene, GAP oral hygiene, laser therapy option and type of laser therapy, and the explanatory variables of gender and experience were analyzed. Results: A total of 33.8% of the dentists had poor general knowledge, 16.5% had fair knowledge, 31.9% had good knowledge, while 10.5% had excellent knowledge. Gender- and experience-related differences were found, but they were not statistically signifi cant. Conclusion: Both the general and specifi c knowledge of aggressive periodontitis among Nigerian dentists is less than expected and needs improvement through targeted, continuing dental education.

    Full Text Available Aims and Objectives : A relationship between poor periodontal health and respiratory disease has been suggested by a number of recent studies. The present study was undertaken to evaluate potential association between respiratory diseases and periodontal health status and to co-relate the severity of periodontal disease with that of chronic obstructive pulmonary disease (COPD. Materials and Methods : 150 patients of COPD (test group and 50 Patients without COPD (control group were recruited for the study. Information regarding patient′s demographic and socioeconomic status and lifestyle (history of smoking were considered in the study. Patients with COPD were grouped into mild, moderate and severe category on the basis of Spirometry. Periodontal health was assessed by measuring probing pocket depth, Clinical Attachment Loss (CAL and Oral Hygiene Index (OHI. Results : The results showed that the subjects with COPD had significantly more mean CAL and a higher mean OHI than those without COPD. The risk for COPD appeared to be significantly elevated when attachment loss was found to be severe. A trend was noted in that lung function appeared to diminish as the amount of attachment loss increased. Conclusion : On the basis of the observed results of the study it can be concluded that the risk for COPD appeared to be significantly elevated when attachment loss was found to be severe. It is conceivable that oral interventions that improve oral health status may prove to lower the severity of lung infection in susceptible populations.

  17. Periodontitis is associated with endothelial dysfunction in a general population: a cross-sectional study.

    Directory of Open Access Journals (Sweden)

    Birte Holtfreter

    Full Text Available A large body of evidence underlines an association between periodontal disease and cardiovascular disease. In contrast, data on its relation with endothelial dysfunction as a marker of early subclinical atherosclerosis is inconclusive and limited to patient-cohort studies. We therefore investigated the association between periodontal disease and flow-mediated dilation of the brachial artery (FMD as a measure of endothelial dysfunction in a general population, and also addressed a possible mediation via inflammation. The study population comprised 1,234 subjects (50.5% men aged 25-85 years from the 5-year follow-up of the Study of Health in Pomerania, a population-based cohort study. Clinical attachment loss (CAL and pocket probing depth (PPD as measures of periodontal disease were assessed half-mouth at four sites per tooth. Subjects were classified according to the periodontitis case definition proposed by Tonetti and Claffey (2005. Measurements of FMD and nitroglycerin-mediated dilation (NMD were performed using standardized ultrasound techniques. High-sensitive C-reactive protein, fibrinogen and leukocyte count were measured. Fully adjusted multivariate linear regression analyses revealed significant associations of the percentage of sites with PPD ≥ 6 mm with FMD (p(trend=0.048, with subjects within the highest category having a 0.74% higher FMD compared to subjects within the lowest category (p<0.05. Consistently, FMD values increased significantly across categories of the percentage of sites with CAL ≥ 6 mm (p(trend=0.01 and the periodontitis case definition (p(trend=0.006. Restrictions to subjects without antihypertensive or statin medication or current non-smokers confirmed previous results. Systemic inflammation did not seem to mediate the relation. Both PPD and CAL were not consistently associated with NMD. In contrast to previous studies, high levels of periodontal disease were significantly associated with high FMD values. This

    Introduction: Langerhans cell histiocytosis (LCH) is a rare inflammatory myeloid neoplasia of unknown etiology occurring in both children and adults. This condition is characterized by an abnormal proliferation of Langerhans cells that may virtually affect all sites in the human body. Oral manifestations of LCH could be the first clinical sign of disease and its periodontal localization could be easily mistaken for other more common entities, such as chronic periodontitis, aggressive periodontitis, and necrotizing ulcerative periodontitis. Case presentation: A 32-years old female visited a private dental practice with a chief complaint of sensitivity in the mandibular left first molar. Clinical and radiographic examination revealed deep periodontal pocket, recession, furcation involvement, mobility, severe alveolar bone destruction and a diagnosis of aggressive periodontitis was rendered. Multiple tooth extractions were carried out due to progressive periodontal destruction with impaired healing and development of ulcerative lesions. Multidisciplinary investigation demonstrated that the periodontal involvement was a manifestation of an underlying systemic disease. A biopsy of a bone lesion was therefore performed, revealing the presence of multifocal single system LCH. Conclusion: The identification of periodontal LCH is not trivial given that it may clinically resemble other periodontal disease entities. The dentist can be the first health care personnel to unravel the presence of an underlying systemic LCH. PMID:26722570

    Full Text Available Malocclusion superimposed with severe periodontitis may present a great challenge to clinicians while providing orthodontic treatment due the episodic and site-specific nature of the disease with risk of rapid tissue breakdown. However, orthodontic treatment in such situation may contribute significantly to the overall rehabilitation both functionally and esthetically. In this article, a case report outlines a combined periodontic-orthodontic management of compromised dentition. A 37-year-old female patient with significant medical history was treated for Class II Division 1 type of malocclusion associated with spaced upper and lower anterior teeth, deep overbite, and increased overjet, superimposed with chronic generalized periodontitis and bone loss. Treatment was completed using temporary anchorage devices assisted strategically applied force and modified tandem retraction biomechanics amidst management of acute inflammatory episodes during and mucogingival complication after treatment. Affected areas healed very well after post-orthodontic periodontal treatment with minimal pocket depth, and bleeding on probing, and a healthy zone of attached gingiva at the follow up visits. The orthodontic results lead to improvement in patient's facial profile, lip posture, and correction of protrusion which addressed her main concern. One year follow-up shows good orthodontic and periodontic stability. The report highlights the importance of identifying “at risk” individuals and continuous monitoring of disease status during treatment. Despite all precautionary measures, a flare-up during the treatment can be anticipated.

    Introduction Periodontitis is still highly prevalent in industrial population whereas at the same time appropriate screening programs are missing. Aim To evaluate, a self-reported questionnaire about periodontal risk factors in combination with the Periodontal Screening Index (PSI) to identify an existing need for periodontal treatment combined with the early recognition of high-risk patients. Materials and Methods Total 200 patients took part in the questionnaire based study and were examined using the PSI. Thereafter the participants were divided into two groups, subjects with periodontitis (Group 1; PSI 0-2) and subjects without periodontitis (Group 2; PSI 3-4). The answers were evaluated using a point system ranging from 0 to 8, based on known periodontal risk factors and their assumed degree of influence. Receiver-Operating Characteristic (ROC) curve analysis were applied to examine the overall discriminatory power, sensitivity, specificity and corresponding cut-off points of the self-reported periodontal disease scale. Results There was a significant difference between Group 1 and 2 concerning the majority of the inquired items (12 of 16, p<0.05). The distribution of the individual total score exhibited a high statistical significance (p<0.001) of robustness in terms of differing definitions of periodontitis. The Area Under the Curve (AUC) was 0.912 with a sensitivity of 86% and a specificity of 76%. Conclusion The questionnaire produced a reliable assessment of the individual risk (total score) and the need for periodontal treatment as well as the differentiation between gingivitis and periodontitis. Clinical relevance Patient-based data (clinical variables and periodontal risk factors of periodontitis) were adequate to make a preliminary assessment of a possible need for periodontal treatment.

    The aim of the article was to study the occurrence of periodontal diseases in children with type I diabetes mellitus. The examination of 78 children revealed periodontal diseases in 40 children with type I diabetes. OHI-S, CPITN, PMA indices were determined. Pathological changes in periodontal tissues were revealed in 100% of cases. The following were identified: gingival hemorrhage (100%), over - and under-gingival dental tartar (100%), inflammation of gingival papilla (87,5%) marginal (80%) and alveolar gingiva (55%). Spread of periodontal disease among children with I type diabetes is characterized as high and is equal to 100%. Degree of periodontal sickness is evaluated as average and is M=2,28; SD=0,47 according to CPITN index. Treatment and preventive measures should be carried out taking into account major somatic disease.

    Full Text Available Background: The Chronic Inflammatory Periodontal Disease is related with multiple risk factors. Those patients with human immunodeficiency virus have higher risk of presenting this disease and it is usually more serious in these cases. Objective: To describe the prevalence of Chronic Inflammatory Periodontal Disease in patients with HIV. Methods: Descriptive, observational, cross-sectional study including patients with HIV in Sancti Spiritus province. The occurrence of the disease was determined after the Periodontics Cuban Standards, and oral hygiene was assessed through the simplified oral hygiene index. Other variables were measured, such as smoking habits, T CD4+ lymphocyte counting and virus load. The independent association of each risk factor with the disease was determined through a logistic regression model. Results: The 56, 5 % of the 154 patients presented Chronic Inflammatory Periodontal Disease; 60 (39.0% gingivitis and 27 (17,5% periodontitis. Gingivitis was associated with poor oral hygiene (OR: 3,71 and periodontitis with smoking habit (OR: 5,20. The severe forms of periodontitis occurred mainly in patients with lymphocyte counting lower than 500 cells/mm3 . Conclusions: The prevalence of Chronic Inflammatory Periodontal Disease in patients with HIV in Sancti Spiritus province is linked to known risk factors such as smoking habits and oral hygiene.

    Evidence based clinical studies have shown exact recommended design for artificial crown reconstruction with acceptable long-term results taking into an account the biological price. Previous histological and clinical studies proved that fixed prostheses might influence the periodontal condition of crowned teeth, if not all biological criteria have been considered. The aim of the present study was to assess the periodontal condition of the crowned teeth after stainless steel swaged crowns were replaced by cast metal ceramic crowns. Participants were selected at the Institute of Stomatology, Stradin's University. Selection criteria included need to replace existing swaged crowns by metal ceramic crowns for patients with absence of any systemic disease. Following symptoms of periodontal condition were examined - presence of inflammation (clinical signs, probing) and pocket depth. Assessments were carried out at four different points of time (first appointment after replacement existing swaged crowns by temporary crowns; two weeks after cementation of permanent metal ceramic restoration; after three month; after six month). Overall bleeding score "2" and "3" at the first measurement was observed in majority of study population. Bleeding scores between the 1st and the 4th measurement was significantly lower (pcrowns by metal ceramic improves gingival health and leads to better long-term prognosis for restored teeth. It is recommended that swaged crowns be replaced with more biologically friendly crowns.

  6. Some aspects of periodontitis pathogenesis in children

    Full Text Available Inflammatory processes in the tissues surrounding tooth root are frequent enough and develop as the direct complication of caries. As acute periodontitis is manifested with grinding toothache and violation of ph¬y¬sio¬logical act of chewing, symptoms of general intoxication, the continuous sluggish chronic periodontitis is harmful and dangerous to the organism as well. It forms the state of chronic оdontogenetic intoxication and chroneosepsis with wrong functioning of some internal organs and body systems. The like complications can cause significant disturbance to the function of kidneys, liver, heart, joints and their treatment without ablating focus of inflammation is often in- effective; this must be taken into account by doctors-interns. However, scanning of the oral cavity by conservative means has its difficulties mostly because of ignoring pathogenesis of such inflammation. That is why activity of ferments of blood dehydrogenases from the periapical tissues of the teeth affected with the chronic periodontitis was studied. The level of succinate dehydrogenase and alpha-glycerophosphate degydrogenase of lymphocytes of 110 schoolchildren aged 13-17 years old was studied. The main group of examined individuals included those of infected with tuber¬culousis – 50 individuals, and the control group (60 individuals – clinically healthy ones without tuberculousis desease. All schoolchildren had 1 or 2 teeth affected with chronic periodontitis of the apical localization. The researchers found that a significant inhibition of activity of succinate dehydrogenase and alpha-glycerophosphate degydrogenase ferments occurs in the inflammatory periodontal tissues, which indicates to local immunity decline, and as a consequence, pathogenic bacteria activation. In people infected with tuberculousis these violations were more developed. Such features of periodontitis pathogenesis must be taken into account when providing a combined treatment.

    Periodontitis remains highly prevalent all over the world and can lead to loss of the affected teeth. Thus, establishing a brand-new treatment that enables the regeneration and rebuilding of periodontal tissue destroyed by periodontitis represents a task of tremendous importance. Our pre-clinical studies and clinical trials suggested that efficacy is expected from basic fibroblast growth factor(FGF-2)in stimulating regeneration of periodontal tissue. Development of the osteoconductive carrier for FGF-2 drug will further extend the indications in the field of dental medicine.

For diagnosis and treatment planing and detection the quality of remaining Alveolar bone the radiography is very useful so the type of radiography is very important. The purpose of this study is the comparison between panoramic, periapical (bisecting technique and vertical bitewing radiographs in diagnosis of periodontitis. Methods. Twelve patients (3 male and 9 female with a mean age of 35, with a moderate to advanced periodontitis were evaluated. At the time of periodontal surgery, in the posterior site of two jaws (in 6 and 7 teeth, the bone loss was measured from CEJ to the base of alveolar bone, and compared with the radiographic findings of proximal bone loss. Results. The average of distance between CEJ and alveolar bone in 48 surfaces were 4.27 in clinic, 4.80 in panoramic, 2.62 in periapical (bisecting technique, 2.98 in vertical bitewing and 4.05 in panoramic without magnification. Discussion. In this research we cancluded that both techniques (periapical and vertical bitewing are not accurate in detection of proximal bone loss and there was significant difference between quantity of proximal bone in clinical measurment than radiographic measurment and this study showed that the panoramic (specially panoramic without magnification is more careful than other radiographic techniques in detection of proximal bone loss.

    Full Text Available Periodontal disease is a major public health issue and the development of effective therapies to treat the disease and regenerate periodontal tissue is an important goal of today′s medicine. Regeneration of periodontal tissue is perhaps one of the most complex process to occur in the body. Langer and colleagues proposed tissue engineering as a possible technique for regenerating the lost periodontal tissues. Tissue engineering is a multidisciplinary field, which involves the application of the principles and methods of engineering and life sciences to help in the development of biological substitutes to restore, maintain or improve the function of damaged tissues and organs. A Google/Medline search was conducted and relevant literature evaluating the potential role of the tissue engineering in periodontal regeneration, which included histological studies and controlled clinical trials, was reviewed. A comprehensive search was designed. The articles were independently screened for eligibility. Articles with authentic controls and proper randomization and pertaining specifically to their role in periodontal regeneration were included. The available literature was analyzed and compiled. The analysis indicate tissue engineering to be a promising, as well as an effective novel approach to reconstruct and engineer the periodontal apparatus. Here, we represent several articles, as well as recent texts that make up a special and an in-depth review on the subject. The purpose behind writing this brief review has been to integrate the evidence of research related to tissue engineering so as to implement them in our daily practice.

    Periostin, a matricellular adapter protein highly expressed by periodontal ligament fibroblasts, is implicated in the maintenance of periodontal integrity, which is compromised during periodontal diseases. The aim of this study was to explore the influence of chronic periodontal inflammation on tissue periostin levels. Periodontal breakdown was induced in a pre-clinical ligature periodontal inflammatory disease model. Periodontal tissue specimens were harvested at baseline, 2 weeks, and 4 weeks and prepared for histologic, immunofluorescence, and micro-CT examination. Statistical analyses were conducted by Kruskal-Wallis, Mann-Whitney, and Spearman’s tests. Periostin detection levels were reduced over time in response to the inflammatory process (1 ± 0.05; 0.67 ± 0.03; 0.31 ± 0.02; p < 0.001; baseline, 2, and 4 weeks, respectively). Simultaneously, alveolar bone loss increased from baseline to the 2- and 4-week time-points (0.40 ± 0.02 mm; 1.39 ± 0.08 mm; 1.33 ± 0.15 mm; p < 0.001), which was inversely correlated with the levels of periostin (ρ = -0.545; p < 0.001). In conclusion, periostin PDL tissue levels significantly decrease under chronic inflammatory response and correlate with the detrimental changes to the periodontium over time. PMID:22933606

    Epithelial cells in oral cavities can be considered reservoirs for a variety of bacterial species. A polymicrobial intracellular flora associated with periodontal disease has been demonstrated in buccal cells. Important aetiological agents of systemic and nosocomial infections have been detected in the microbiota of subgingival biofilm, especially in individuals with periodontal disease. However, non-oral pathogens internalized in oral epithelial cells and their relationship with periodontal status are poorly understood. The purpose of this study was to detect opportunistic species within buccal and gingival crevice epithelial cells collected from subjects with periodontitis or individuals with good periodontal health, and to associate their prevalence with periodontal clinical status. Quantitative detection of total bacteria and Staphylococcus aureus, Pseudomonas aeruginosa and Enterococcus faecalis in oral epithelial cells was determined by quantitative real-time PCR using universal and species-specific primer sets. Intracellular bacteria were visualized by confocal microscopy and fluorescence in situ hybridization. Overall, 33% of cell samples from patients with periodontitis contained at least one opportunistic species, compared with 15% of samples from healthy individuals. E. faecalis was the most prevalent species found in oral epithelial cells (detected in 20.6% of patients with periodontitis, P = 0.03 versus healthy individuals) and was detected only in cells from patients with periodontitis. Quantitative real-time PCR showed that high levels of P. aeruginosa and S. aureus were present in both the periodontitis and healthy groups. However, the proportion of these species was significantly higher in epithelial cells of subjects with periodontitis compared with healthy individuals (P = 0.016 for P. aeruginosa and P = 0.047 for S. aureus). Although E. faecalis and P. aeruginosa were detected in 57% and 50% of patients, respectively, with probing depth and

    Aim The purpose of the present study was to assess the extent to which the three periodontitis case definition systems proposed by van der Velden, Tonetti & Claffey and Page & Eke identify the same cases in a population of never-treated adults with limited tradition for oral hygiene procedures...... of the concomitant presence of CAL and BOP at the site level. Results The case definitions by Tonetti & Claffey and by Page & Eke yielded similar results, which were also quite similar to the results of simply identifying a case of periodontitis as a person having at least one site showing both CAL ≥ 4 mm and BOP....... Conclusions The results indicate that it should be feasible for the periodontal community to reach an agreement over the distinction between a case and a non-case. The classification system proposed by van der Velden is better suited for providing clinicians with a clear image of the case....

    Full Text Available 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.

  2. Evaluation of a model for induction of periodontal disease in dogs

    Full Text Available There are several methods for inducing periodontal disease in animal models, being the bone defect one of the most reported. This study aimed to evaluate this model, through clinical, radiographic, tomographic and histological analyzes, thus providing standardized data for future regenerative works. Twelve dogs were subjected to the induction protocol. In a first surgical procedure, a mucoperiosteal flap was made on the buccal aspect of the right third and fourth premolars and a defect was produced exposing the furcation and mesial and distal roots, with dimensions: 5mm coronoapical, 5mm mesiodistal, and 3mm buccolingual. Periodontal ligament and cementum were curetted and the defect was filled with molding polyester, which was removed after 21 days on new surgical procedure. Clinical and radiographic examinations were performed after the two surgeries and before the collection of parts for dental tomography and histological analysis. All animals showed grade II furcation exposure in both teeth. Clinical attachment level increased after induction. Defect size did not change for coronoapical and buccolingual measurements, while mesiodistal size was significantly higher than at the time of defect production. Radiographic analysis showed decreased radiopacity and discontinuity of lamina dura in every tooth in the furcation area. The horizontal progression of the disease was evident in micro-computed tomography and defect content in the histological analysis. Therefore, it is concluded that this method promotes the induction of periodontal disease in dogs in a standardized way, thus being a good model for future work.

    The radiographs play an important role in the diagnosis and management of periodontal disease although the most appropriate form of assessment vary. The great technologic advance and the easily accessible systems of digital image analyses, specify digitized radiographs, improve the diagnostic power. The studied group was 29 adults (14 female and 15 male) ranging in age from 18 to 45 years. They all had evidence of alveolar bone loss and established periodontitis. They were studied, without treatment, over a six month period with four posterior standardized vertical bite wings radiographs, electronic probing of attachment loss, and bacteriological and temperature analysis of periodontal pocket. The aim of this investigation was to determine the relationship between the loss of radiographic crestal bone height and probing attachment loss in digitized radiographs and show a standardization method for periodontal radiographs. Radiographic and probing attachment change at all sites, dichotomously classified as to not changing or loosing indicated 20.42% of sites were loosing by measurement of radiographic change and 5.29% were loosing by measurement of attachment change. There was concordance between the presence or absence of probing attachment loss and bone loss in 72% to 86% depending on the area. The results, admitting methodological limitations, indicate that when these two methods for the assessment of progressive periodontitis were used they represents measure degrees of different features of periodontitis and that the period of periodontal disease activity was detected in the either the soft tissue attachment or bone.

    Periodontitis, the progressive loss of the alveolar bone around the teeth and the major cause of tooth loss in adults, is due to oral microorganisms, including Porphyromonas gingivalis. Periodontitis is associated with a local overly aggressive immune response and a spectrum of systemic effects, but the role of this condition in orodigestive cancers is unclear. We prospectively examined clinically ascertained periodontitis (N = 12 605) and serum IgG immune response to P.gingivalis (N = 7852) ...

    Periodontal medicine has been studied and reviewed extensively since its introduction to the dental fraternity. The association of periodontal disease with and its effects on the cardiovascular system are amongst the many topics explored. A summary of the research into these associations and the possible mechanisms of any relationship is presented. Although a link between these two chronic inflammatory diseases is evident, the very heterogeneity of the relevant studies has not provided evidence sufficient to support an actual causal relationship. More stringent epidemiologic and intervention studies are required. PMID:23951765

    2006-08-01

    Full Text Available Background and Aim: Several risk factors directly affect the development of periodontal diseases. Also some systemic diseases act indirectly as predisposing and aggrevating factors. Osteoporosis is one of these factors and one of its main causes is lack of physical activity in postmenopause period. The incidence of osteoporosis is increasing in our country. The goal of this study was to evaluate the periodontal condition of women with osteoporosis and osteopenia referred to bone densitometric division of Loghman hospital in 2003 and compare to control group. Materials and Methods: In this case control study based on BMD (Bone Mineral Density measurement of back and thigh using DEXA method, 60 patients referred to bone densitometric division of Loghman hospital, were randomly selected. Cases were divided into three groups, 20 with osteoporosis, 20 with osteopenia and 20 normal cases. Periodontal indices consisting of plaque index (PI, tooth loss (TL, gingival recession (GR, probing pocket depth (PPD and papilla bleeding index (PBI were evaluated by clinical and radiographic examination. Data were analyzed by Kruskall Wallis and Dunn tests with p<0.05 as the limit of significance. Results: PBI, PI and TL were significantly higher in osteoporotic group than osteopenic and normal group. PPD was not different in the three groups. Due to the low prevalence of recession in our study, this parameter was not included in the statistical analysis. Conclusion: It seems that osteoporosis does not increase the incidence of periodontal diseases because it affects bone quality rather than quantity. In osteoporosis calcium deficiency and increasing age lead to decreased physical activity and ultimately affect the patient's oral hygiene performance. Thus, periodontal manifestations are presented as gingival bleeding and gingivitis.

    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 <0.00001). The severity of 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.

The aim of this study was to evaluate the efficacy and safety of locally administered minocycline microspheres (Arestin TM in the treatment of chronic periodontitis. Materials and Methods: A total of 60 sites from 15 patients in the age group of 35-50 years, who had periodontal pockets measuring 5-8mm and had been diagnosed with chronic periodontitis, were selected for the study. The selected groups were randomly assigned to either the control group (group A or the treatment/test group (group B. Only scaling and root planing were done at the base line visit for the control sites followed by local application of Arestin™ (1mg. Clinical parameters such as plaque index, gingival index, and gingival bleeding index were recorded at baseline, day 30, day 90, and day 180 in the selected sites of both the groups. Probing pocket depth also was recorded at baseline, day 90, and day 180 for both the groups. Results: A statistically significant reduction was observed in both groups. Group B showed better results than Group A and these differences were statistically significant. Conclusion: The results of this study clearly indicate that treatment with scaling and root planing plus minocycline microspheres (Arestin™ is more effective and safer than scaling and root planing alone in reducing the signs of chronic periodontitis.

  16. 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.

    2016-02-01

    Periodontal disease (PD) and cardiovascular disease (CVD) are highly prevalent in the modern community. Both pathologies are chronic inflammatory disorders, which are influenced by multiple risk factors. In part, these factors such as age, smoking, and diabetes overlap between PD and CVD. Epidemiological studies suggest that PD is strongly associated with increased CVD risk. Biochemical and physiological analyses involving in vitro experiments, animal models, and clinical studies provided evidence for the substantial impact of periodontal pathogens, their virulence factors, and bacterial endotoxins on all general pathogenic CVD mechanisms such as endothelial dysfunction, systemic inflammation, oxidative stress, foam cell formation, lipid accumulation, vascular remodeling, and atherothrombosis. Interventional studies showed moderate beneficial effects of PD treatment on reducing systemic inflammation and endothelial dysfunction. However, no interventional studies were performed to assess whether periodontal therapy can primarily prevent CVD. In summary, current data suggest for a strong contributory role of periodontal infection to CVD but cannot provide sufficient evidence for a role of PD as a cause for cardiovascular pathology.

Both organisms were isolated using a trypticase soy agar-bacitracin-vancomycin (TSBV medium and detected by PCR. Conventional biochemical tests were used for bacteria identification. RESULTS: A. actinomycetemcomitans and F. nucleatum were isolated in 18% and 20% of the patients, respectively, and in 2% and 24% of healthy subjects. Among A. actinomycetemcomitans isolates, biotype II was the most prevalent. Primer pair AA was 100% sensitive in the detection of A. actinomycetemcomitans from both subject groups. Primers ASH and FU were also 100% sensitive to detect this organism in healthy subject samples. Primer pair FN5047 was more sensitive to detect F. nucleatum in patients or in healthy samples than primer 5059S. Primers ASH and 5059S were more specific in the detection of A. actinomycetemcomitans and F. nucleatum, respectively, in patients and in healthy subject samples. CONCLUSIONS: PCR is an effective tool for detecting periodontal pathogens in subgingival samples, providing a faster and safer diagnostic tool of periodontal diseases. The method's sensitivity and specificity is conditioned by the choice of the set of primers used.

    Periodontal treatment may improve the metabolic control of dyslipidemia. The aim of this study was to evaluate the lipid profile and high-sensitivity C-reactive protein (hs-CRP) levels in obese and non-obese patients undergoing periodontal therapy. Patients with generalized chronic periodontitis were divided into obese (n = 28) and non-obese groups (n = 26). The periodontal parameters (visible plaque index, gingival bleeding index, probing depth, clinical attachment level, and bleeding on probing), anthropometric measurements (body mass index, waist circumference, and body fat), and serum analyses (triglycerides, total cholesterol, high-density lipoprotein, low-density lipoprotein, fasting glucose, glycated hemoglobin, and hs-CRP) were measured at baseline and 90 days after periodontal treatment. The results showed that the obese subjects presented alterations in triglycerides, total cholesterol, low-density lipoprotein, and hs-CRP at baseline when compared with non-obese patients (P 0.05). Obese subjects showed a significant decrease in the levels of triglycerides, total cholesterol, low-density lipoprotein, and hs-CRP post-therapy (P Lipid profile was modified only in obese patients post-therapy.

    Full Text Available The aims of this double-blind randomized clinical trial were to evaluate the presence of periodontal pathogens and the clinical response of periodontal pockets treatment to scaling and root planing (SRP associated with subgingival minocycline (SM. A total of 36 subjects, 26 to 60 years old (40.7 ± 9.1, who had been previously diagnosed with chronic periodontitis, were included in the present study. Eighteen subjects were selected for the test group (TG, who were treated with SRP plus SM (new treatment, and 18 subjects for the control group (CG who received SRP plus vehicle (current treatment. Two homologous sites in each subject with a probing depth (PD > 6 mm were chosen. To evaluate the clinical response after treatment, PD was measured at baseline and at 90 days. Microbiological evaluation was performed to detect 7 periodontal pathogens using polymerase chain reaction at baseline, 30, and 120 days. A mean reduction in PD of 2.8 and 2.1 mm was observed in the TG and CG, respectively. At baseline, P. gingivalis was the most prevalent organism in both test (65.8% and control (48.6% groups. After 120 days it fell to 30.8% in TG and to 23.1% in CG. There were no statistically significant differences between the test and control groups concerning PD (p > 0.05 by Wilcoxon test or presence of periodontal pathogens (p > 0.05 by Wilcoxon and chi-square; p > 0.01 by Signal test. The results observed showed that the new treatment was as effective as the current treatment in reducing periodontal pathogens and PD among chronic periodontitis subjects.O objetivo deste estudo randomizado duplo-cego foi avaliar a presença de periodontopatógenos e o comportamento clínico de bolsas periodontais tratadas com raspagem e aplainamento radicular (RAR associado à minociclina subgengival (MS.

    Background: Ki-67 which is a non-histone nuclear protein which is expressed in proliferating cells, during all the active phases of the cell cycle. Increased Ki-67 expression has been seen in several inflammatory and malignant conditions like diabetes, rheumatoid arthritis, atherosclerosis, pancreatitis and squamous cell carcinoma. Aim: The aim of the present study is to analyze the expression of Ki-67 in gingival tissues by immunohistochemistry in smokers and non-smokers with healthy gingiva and chronic periodontitis. Materials and Methods: Gingival biopsies (n = 32) were obtained from smokers who had clinically healthy gingiva (n = 8), smokers with periodontitis (n = 8), chronic periodontitis (n = 8) and healthy gingiva (n = 8). The expression of Ki-67 was evaluated immunohistochemically. Statistical analysis used: Mean and standard deviation were estimated for the gingival tissue extract sample for each study group. Mean values were compared between different study groups by, one way ANOVA, post hoc analysis. In this study P < 0.05 was considered as the level of significance. Results: The mean number of Ki-67 positive cells/field was higher in the smokers with periodontitis group. When the mean Ki-67 positive cells were compared between different groups, statistical significant difference was observed between healthy and both the periodontitis groups (P = 0.000) and between smokers group (P = 0.001). Conclusions: Ki-67 was maximally expressed in smoker with periodontitis followed by chronic periodontitis patients, healthy smokers and healthy control patients which shed light on the toxic effects of tobacco in dysregulating the cell cycle and cellular proliferation. The findings of this study also help us to understand the role of the cell cycle in resolution of periodontal inflammation which is a salient feature in the pathogenesis of chronic periodontitis.

    1. An overdenture, whether complete or partial, is an excellent mode of treatment in the mutilated dentition for the preservation of the residual ridge. 2. Selection of patients for an overdenture should be based on past history of dental neglect, the status of the teeth and their periodontium, including present oral hygiene status, and patient motivation. The patients with a history of dental neglect, poor oral hygiene, and lack of motivation in having the teeth and the periodontium restored to health as well as strict compliance to a home-care regimen and recall schedule are not good candidates for treatment with an overdenture. 3. The choice of teeth or roots to serve as overdenture abutments must include their periodontal evaluation, which should consist of a detailed periodontal examination, diagnosis, prognosis, and treatment when this is indicated, including chemical protection (fluoride gel) and an oral hygiene regimen tailored to individual needs. 4. The knowledge and expertise in the selection and implementation of appropriate periodontal treatment modalities is of paramount importance in restoring optimum periodontal health to the overdenture abutments before overdenture fabrication. 5. The maintenance phase of the overdenture abutments as well as of the existing natural teeth is of critical importance in the preservation of health of these abutments and teeth. This maintenance phase should consist of periodic recalls based on individual needs; a detailed periodontal evaluation, including patient's motivation and status of oral hygiene and denture hygiene; and detection of caries. If necessary, appropriate periodontal and/or restorative therapy should be performed, and oral hygiene measures reinforced. This will ensure longevity of both abutment teeth or roots and of the existing natural teeth resulting in a long-term success of an overdenture. 6. Because there is evidence of high incidence of periodontal disease and dental caries in overdenture wearers

    embargo, se logró una mayor reducción del dolor en aquellos pacientes que utilizaron la terapia de arginina al 8% y carbonato de calcio, con un 60% de los individuos sin dolor y con una mediana final de 0 en comparación al grupo con barniz de flúor al 5% y un dentrífico fluorado que mantuvieron en el 100% de los sujetos algún grado de dolor y presentando una mediana final en la escala VAS de 2.Aim: The aim of this clinical study was to evaluate and to compare the efficacy in reducing the dentine hypersensitivity of an 8% arginine, calcium carbonate, 1.450 ppm sodium monofluorophosphate dentifrice with topical application and twice-daily brushing, with a negative control toothpaste containing calcium carbonate and 1.450 ppm fluoride as MFP, after periodontal treatment (baseline and four weeks respectively. Methods: A four-week clinical study with 20 subjects with diagnosis of slight to moderate chronic periodontitis under mechanical periodontal treatment and presence of gingival recessions in incisors, canines or premolars, stratified based on baseline tooth sensitivity. Subjects brushed with either a 1.450 ppm fluoride dentifrice or a marketed 8% arginine calcium carbonate dentifrice twice daily for approximately one minute. At screening, baseline and weeks four, subjects' tooth sensitivity was determined through both evaporative (Schiff and Visual Analogue Scale [VAS]. The same examiner throughout the study performed subject assessments using each stimulus. Results: Both subject groups exhibited significant reductions from baseline to four weeks in dentine hypersensitivity. However, patients who received 8% arginine calcium carbonate therapy, exhibited a greater reduction, with a 60% of individuals lacking of pain and with a final median of 0 in comparison with the 5% fluoride varnish and fluoride toothpaste group in which a 100% of subjects felt some degree of pain, presenting a final medium VAS scale of 2.

    para minimizar a provável transmissibilidade de microrganismos bucais patogênicos para a criança, obtendo assim uma prevenção primária das principais doenças bucais.PURPOSE: The assessment using the PSR (Periodontal Screening and Recording of the prevalence and severity of and the basic treatment needs for periodontal disease in a group of pregnant women who attended the Preventive Dentistry Clinic at the School of Dentistry of Araraquara - UNESP. METHODS: Forty-one pregnant women of 16 to 37 years of age, were examined. The PSR index was evaluated with a suitable periodontal probe (Trinity - model 621-WHO with index codes scores of from 0 to 4, capable of indicating the presence of the following conditions: periodontal health, bleeding on probing, calculus, shallow and deep pockets. These codes were attributed to each sextant and could be marked with an asterisk (* to indicate the presence of gingival recession, furcation lesions, mobility or any other mucogingival alterations. RESULTS: It is shown that 100% of the pregnant women had some kind of gingival alteration, represented mainly by PSR code 2 (56.1% and " * " (19.5%. The women in the youngest age groups, 15-19 and 20-24 years, had code 2 as their highest score with no sextant excluded. In the 25-29 age group, the PSR code 2 still prevailed (54.5% although codes 3 and 4 were already appearing. The code " * " and the ocurrence of excluded sextants tended to increase in the oldest age group (30-37. In general, the affected sextants showed codes 1 and 2 more frequently, corresponding to 41.6% and 39.8% respectively, which represented a mean of 2.49 and 2.39 sextants affected in each pregnant woman. Regarding the treatment needs, 90.2% of the women needed some treatment beyond the preventive measures begun, incl
