    Nail-biting is one of the most frequent deleterious oral habits in children. It can result in systemic diseases or oral traumatic lesion. This report describes a case of gingival abscess in a child due to a fingernail-biting habit. A 5-year, 6-month-old female presented gingival swelling and fistula in the primary maxillary left central and right lateral incisors as an unusual sequelae to the periodontal tissues from fingernail-biting. A periodontal curette was used to remove the fragments and to curette the area. After the curettage, an exudate of blood and pus was drained. Then the area was irrigated with 0.12% chlorhexidine solution; applying finger pressure controlled the secretion. After one week, the patient returned with gingival swelling present in the same teeth. The same curettage procedure was performed. It was suggested that the deleterious habit was related to emotional tension and anxiety behaviors and the patient was referred for psychological treatment. When the patient returned one month later, she was still biting her fingernails, but she had stopped placing fragments into the gingival crevice. No more gingival inflammation or swelling was observed. his paper presents an unusual case report of a gingival abscess due to a fingernail-biting habit in a child, probably related to an emotional condition. The fingernail-biting habit can induce a periodontal traumatic injury yielding a more serious complication such as a gingival abscess.

    The aim of this study was to compare the proteome composition of gingival crevicular fluid obtained from healthy periodontium, gingivitis and chronic periodontitis affected sites. Owing to its site-specific nature, gingival crevicular fluid is ideal for studying biological processes that occur during periodontal health and disease progression. However, few studies have been conducted into the gingival crevicular fluid proteome due to the small volumes obtained. Fifteen males were chosen for each of three different groups, healthy periodontium, gingivitis and chronic periodontitis. They were categorized based on clinical measurements including probing depth, bleeding on probing, plaque index, radiographic bone level, modified gingival index and smoking status. Gingival crevicular fluid was collected from each patient, pooled into healthy, gingivitis and chronic periodontitis groups and their proteome analyzed by gel electrophoresis and liquid chromatography electrospray ionization ion trap tandem mass spectrometry. One hundred and twenty-one proteins in total were identified, and two-thirds of these were identified in all three conditions. Forty-two proteins were considered to have changed in abundance. Of note, cystatin B and cystatin S decreased in abundance from health to gingivitis and further in chronic periodontitis. Complement proteins demonstrated an increase from health to gingivitis followed by a decrease in chronic periodontitis. Immunoglobulins, keratin proteins, fibronectin, lactotransferrin precursor, 14-3-3 protein zeta/delta, neutrophil defensin 3 and alpha-actinin exhibited fluctuations in levels. The gingival crevicular fluid proteome in each clinical condition was different and its analysis may assist us in understanding periodontal pathogenesis. © 2014 John Wiley & Sons A/S.

    Gingivitis due to sarcoidosis is a relatively rare condition. Gingivitis or isolated gingival involvement may be the first sign of systemic sarcoidosis. We report the case of a 37 year-old woman with isolated gingivitis due to sarcoidosis confirmed by biopsy. Following treatment with a systemic corticosteroid (prednisolone 40 mg/day), all clinical and radiologic findings were completely improved. In cases of chronic and intractable gingivitis, systemic sarcoidosis should be suspected. It should be confirmed with a biopsy, and the patient should be referred to a chest disease clinic to exclude other organ involvement. Copyright © 2013 Elsevier Inc. All rights reserved.

    The effective cleaning of interdental spaces using toothbrushes is a challenge. The aim of the present in vitro study was to evaluate on the one hand the interdental cleaning efficiency and on the other hand the gingival injury potential of an electric single-headed sonic toothbrush (Water-pik) and two single-tufted manual toothbrushes (Curaprox 1009; Lactona Interdental Brush). Brushes were evaluated using a brushing device. Test dental casts (maxillary sextants) consisting of black teeth coated with white paint were brushed using standardized horizontal movements. Thereafter, black (i.e. cleaned) areas were measured planimetrically. The soft tissue injury potential was evaluated using front segments of porcine mandibles. In the same brushing device, test brushes were moved over the gingiva. Before and after each treatment, the porcine mucosa was stained with a plaque disclosing agent to visualize injured areas, which could then be measured planimetrically as well. These evaluations were each made after 15, 30, 60, and 120 seconds of brushing. The statistical analysis was performed using non-parametric Mann-Whitney tests, and the level of significance was set at 5%. The best cleaning performance of 46% across all interdental spaces assessed was found with the electric sonic toothbrush (Waterpik), while the performances of the manual brushes from Lactona and Curaprox were 14.8% and 5%, respectively. At each point of evaluation, the gingiva was injured most markedly by the powered sonic toothbrush (Waterpik), followed by the manual Curaprox brush. The smallest damage of the porcine gingiva was produced by the manual Lactona brush. When comparing the manual toothbrushes, the Lactona product revealed a better cleaning performance combined with a smaller injury potential than the Curaprox brush. Thus, the prophylactic goal to achieve high degrees of cleaning while producing minimal damage is important and should have priority when evaluating and selecting toothbrushes.

    Aims We investigated the sequential gene expression in the gingiva during the induction and resolution of experimental gingivitis. Methods Twenty periodontally and systemically healthy non-smoking volunteers participated in a 3-week experimental gingivitis protocol, followed by debridement and 2-week regular plaque control. We recorded clinical indices and harvested gingival tissue samples from 4 interproximal palatal sites in half of the participants at baseline, Day 7, 14 and 21 (‘induction phase’), and at day 21, 25, 30 and 35 in the other half (‘resolution phase’). RNA was extracted, amplified, reversed transcribed, amplified, labeled and hybridized with Affymetrix Human Genome U133Plus2.0 microarrays. Paired t-tests compared gene expression changes between consecutive time points. Gene ontology analyses summarized the expression patterns into biologically relevant categories. Results The median gingival index was 0 at baseline, 2 at Day 21 and 1 at Day 35. Differential gene regulation peaked during the third week of induction and the first four days of resolution. Leukocyte transmigration, cell adhesion and antigen processing/presentation were the top differentially regulated pathways. Conclusions Transcriptomic studies enhance our understanding of the pathobiology of the reversible inflammatory gingival lesion and provide a detailed account of the dynamic tissue responses during induction and resolution of experimental gingivitis.

    IL-34 is a protein associated with bone degenerative diseases but the role in periodontal disease is unknown. The aim of this study was to assess the expression of IL-34 in primary human gingival fibroblasts (GF) and investigate if the expression is regulated by the pro-inflammatory cytokines interleukin-1 (IL-1β) and tumor necrosis factor α(TNF-α). We also investigated if IL-34 is detectible in gingival crevicular fluid (GCF) in healthy, gingivitis and periodontitis sites. Furthermore, we e...

    Full Text Available Gingival enlargements are quite common and may be either inflammatory, noninflammatory, or a combination of both. Gingival hyperplasia is a bizarre condition causing esthetic, functional, psychological, and masticatory disturbances of the oral cavity. Causes of gingival enlargement can be due to plaque accumulation, due to poor oral hygiene, inadequate nutrition, or systemic hormonal stimulation (Bakaeen and Scully, 1998. It can occur as an isolated disease or as part of a syndrome or chromosomal abnormality. A progressive fibrous enlargement of the gingiva is a facet of idiopathic fibrous hyperplasia of the gingiva (Carranza and Hogan, 2002; Gorlin et al., 1976. It is described variously as fibromatosis gingivae, gingivostomatitis, hereditary gingival fibromatosis, idiopathic fibromatosis, familial elephantiasis, and diffuse fibroma. We present a case of idiopathic gingival fibromatosis with its multidisciplinary approach of management.

    Full Text Available Background: One of the major direct or indirect targets of ultraviolet exposure of skin is the melanocyte or the melanin -forming cell. Epidermal melanocytes act as a trap for free radicals. Based on the protective role of melanocytes in medical literature, the role of melanin pigmentation in gingiva needs to be elucidated. Periodontal pathogens and their products demonstrate the ability to induce the generation of reactive oxygen species. Hence purpose of this study was to unravel the protective role of melanin (if any against the gingival inflammation. Materials and Methods: A total of 80 subjects; 20 in each group were selected. The selection of subjects regarding gingival pigmentation was based on Dummett′s scoring criteria 0, 3. A complete medical, dental history and an informed consent were obtained from the patients. After evaluation of clinical parameters the GCF was collected using microcapillary pipettes at the selected sites. IL-1β levels were quantitated using ELISA. Results: In non-pigmented healthy and gingivitis groups, there was a positive correlation between plaque index, gingival index and bleeding index versus IL-1β level: indicating an increase in the biochemical mediator of inflammation corresponding to an increase in the clinical parameters of inflammation. Also a positive correlation was found between the gingival index and bleeding index versus the IL-1β levels in the pigmented healthy group. The pigmented gingivitis groups showed a negative correlation between the plaque index, gingival index and bleeding index. Conclusions: The clinical markers of inflammation such as gingival index, bleeding index was of low numerical value in pigmented group than in the non-pigmented group, supposedly due to the protective action of melanin. The negative correlation of clinical markers of inflammation to the IL-1β levels in the pigmented gingivitis group could possibly be attributed to the protective role of melanins.

    Both anaphylaxis and head injury are often seen in the emergency department, but they are rarely seen in combination. We present a case of a 30-year-old woman who presented with anaphylaxis with urticaria and angioedema following a minor head injury. The patient responded well to intramuscular epinephrine without further complications or airway compromise. Prior case reports have reported angioedema from hereditary angioedema during dental procedures and maxillofacial surgery, but there have not been any cases of first-time angioedema or anaphylaxis due to head injury.

    Aim Macrolide antibiotics yield high concentrations in inflamed tissue, suggesting that their levels in gingival crevicular fluid (GCF) could be increased at gingivitis sites. However, the increased volume of GCF associated with gingivitis could potentially dilute macrolides. To determine whether these assumptions are correct, the bioavailability of systemically-administered azithromycin was compared in GCF from healthy and gingivitis sites. Materials and methods Experimental gingivitis was induced in one maxillary posterior sextant in nine healthy subjects. Contralateral healthy sextants served as controls. Subjects ingested 500 mg of azithromycin followed by a 250 mg dose 24 hours later. Four hours after the second dose, plaque was removed from experimental sites. GCF was collected from 8 surfaces in both the experimental and control sextants and pooled separately. GCF samples were subsequently collected on the 2nd, 3rd, 8th and 15th days and azithromycin content was determined by agar diffusion bioassay. Results On days 2 and 3, the pooled GCF volume at experimental sites was significantly higher than at control sites (P gingivitis sites and healthy sites, suggesting that the processes that regulate GCF azithromycin concentration can compensate for local inflammatory changes.

    Full Text Available Gingival overgrowths found in the oral cavity are mostly due to reactive hyperplasia and rarely depict neoplastic nature. It is a challenge for the clinician to give final diagnoses of gingival overgrowth. Gingiva is a common site for various benign and malignant lesions. Oral cavity is an ideal niche for the manifestation of various precancerous and cancerous lesions. Fibrous growths present in the oral cavity include a varying group of reactive, precancerous, and cancerous conditions. This report describes a case of a 55-year-old male who clinically presented with a localized fibromatous gingival overgrowth in relation to lower left mandibular canine-premolar region that was diagnosed as a gingival fibroma associated with leukoplakia. On histopathological examination, it was diagnosed as a case of proliferative verrucous leukoplakia. Many a times, clinicians face dilemma while diagnosing an overgrowth as it is difficult to differentiate clinically. Hence, a thorough clinical knowledge and a pathologist's opinion become mandatory to give final diagnosis to such gingival overgrowths.

    A synthetic study was performed on some of those to whom Thorotrast had been injected, in Japan. In the epidemiological study of 147 war woundeds to whom Thorotrast had been injected, it was noted that the Thorotrast injection increased the mortality rate and the incidences of malignant hepatic tumor, liver cirrhosis, and hematological diseases. Clinical study of 44 of them showed that the Thorotrast injection resulted in liver and hematopoietic hypofunctions. Analysis of the dissection of the injected area in 118 cases showed malignant hepatic tumor in 63.5%, liver cirrhosis in 14.4% and hematological diseases in 10.2%. The total of the three types of disease was 88.1%. Histological classification showed that of the malignant hepatic tumors due to Thorotrast, hepatobiliary cancer and hemangioendothelioma of the liver were frequent. By the comparison of the absorbed dose in the liver of the malignant hepatic tumors due to Thorotrast with that of the cancers developed in animal experiments, it was noted that the carcinogenic dose was a mean of 2,000 - 3,000 rad by accumulated dose. It was elucidated that carcinogenesis and fibrination were primary in injury due to Thorotrast, i.e., late injury due to Thorotrast, and that the increase in the accumulated dose in rogans and the increase of the local dose due to the gigantic growth of Thorotrast granules in organs greatly influenced carninogenesis and fibrination.

    Full Text Available ResumenLa ingesta de algunos medicamentos puede producir un sobre crecimiento de las encías. Se reportan medicamentos tales como los bloqueadores de los canales de calcio, inmunosupresores, anticonvulsivantes que producen estos efectos adversos. Múltiples casos de agrandamientos gingivales están asociados a la ingesta de Fenitoína. El tratamiento de los agrandamientos gingivales inducidos por drogas por lo general es quirúrgico, pero mantener un buen control de placa bacteriana puede evitar en muchos casos que se presente un exagerado aumento de volumen gingival. Se presenta un caso de agrandamiento gingival en paciente masculino de 22 años de edad, bajo tratamiento antiepiléptico con fenitoína. Al examen clínico se observó aumento del volumen gingival de forma generalizada, en maxilar superior e inferior, predominante en sector anterior, produciendo ardor y sangrado durante el cepillado y la ingestión de alimentos. Al sondaje presenta múltiples pseudobolsas en los diferentes cuadrantes. La radiografía panorámica reveló pérdida ósea moderada horizontal, predominante en el sector posterosuperior, posteroinferior y anteroinferior. El plan de tratamiento consistió en fase higiénica, instrucción y motivación en higiene oral a la madre, gingivectomía y gingivoplastía en ambos maxilares. (DUAZARY 2011 No. 2, 226 - 231Abstract The importance of endodontic treatment is to achieve a complete filling and sealing of the root canal to prevent the transport of contaminants to and from root canal, with materials compatible with the surrounding tissues. Occasionally a situation may arise in which the purpose of the maintenance of working length is compromised such as overenlargement. This situation allows the extrusion of filling materials, mainly sealer cements, causing post treatment complications such as inflammatory reactions, injury to adjacent structures (orbital pain, inferior alveolar nerve injury, headache, etc., and infections

    Full Text Available Se estudiaron 30 sitios o áreas periodontales que presentaban gingivitis y 30 con periodontitis, con el objetivo de determinar la relación existente entre el sangramiento gingival y la flora microbiana presente en la gingivitis y la periodontitis. Los pacientes seleccionados no presentaban antecedentes de enfermedad general y no habían recibido medicación antimicrobiana ni tratamiento periodontal en los útimos 6 meses; en el caso de las mujeres, no podían estar embarazadas. En los dientes seleccionados se procedió a tomar la muestra cumpliendo con los requisitos establecidos; luego se examinó inmediatamente en el microscopio de campo oscuro. Los resultados obtenidos indican que no hubo relación entre los morfotipos microbianos y los diferentes valores del índice de sangramiento gingival.Thirty periodontal sites presenting with gingivitis and 30 with periodontitis were studied with the aim of determining the relation between gingival bleeding and microflora present in gingivitis and periodontitis. Patients selected for the study did not present with a history of systemic diseases and received neither antimicrobial medication nor periodontal treatment during the last 6 months, in the case of women it was required that they were not pregnant. The sample was taken in the teeth chosen in compliance with the requirements established; then the sample was immediately examined in the dark field microscope. Results obtained suggest that there was no relationship between microbial morphological types and the different values of the gingival bleeding index.

    Full Text Available Recalcitrant gingival erythematous lichen planus lesions comprise a considerable therapeutic problem. This case of chronic desquamative gingivitis in a 25-year-old woman with erosive oral lichen planus was treated with topical and systemic corticosteroid administration, followed by placement of a free gingival graft on right upper quadrant. Although recurrence of the lesions was observed following both treatment modalities, free gingival graft despite being an aggressive therapy, proved more effective and with fewer side effects compared with topical or systemic steroid therapy, and seems to be a promising treatment modality with the benefit of more stable results, among others.

    Full Text Available Background: Traumatic injuries to the oral mucosa in fixed orthodontic patients are common, especially in the first week of bracket placement, and occasionally lead to the development of aphthous stomatitis or ulcers. Nevertheless, these lesions are selflimiting. Purpose: The objective of this study is to reveal the connection between chronic gingivitis and aphthous stomatitis which is still unclear. Case: A patient with a persistent lesion for more than six months. Case Management: RAS was treated with scaling procedure, the gingival inflammation was healed. However, in this case report, despite the appropriate management procedures had been done, the lesion still worsen and became more painful. Moreover, the symptoms did not heal for more than two weeks. Actually, they had been undergone orthodontic treatment more than six months and rarely suffered from aphthous stomatitis. Coincidentally, at that time they also suffered from chronic gingivitis. It was interesting that after scaling procedures, the ulcer subsides in two days. Conclusion: Recently, the neuroimmunobiological researches which involved neurotransmitters and cytokines on cell-nerve signaling, and heat shock proteins in gingivitis and stomatitis are in progress. Nevertheless, they were done separately, thus do not explain the interrelationship. This proposed new concept which based on an integrated neuroimmunobiological approach could explain the benefit of periodontal treatment, especially scaling procedures, for avoiding prolonged painful episodes and unnecessary medications in aphthous stomatitis. However, for widely acceptance of the chronic gingivitis and aphthous stomatitis relationship, further clinical and laboratory study should be done. Regarding to the relatively fast healing after scaling procedures in this case report; it was concluded that the connection between chronic gingivitis and aphthous stomatitis is possible.

    Generalized gingival enlargement is characterized by massive and exuberant gingival overgrowth that poses social, aesthetic, phonetic and functional problems for the patient. Therefore, it requires meticulous management. Objective: To describe the surgical management of generalized gingival enlargement by electrosurgical excision of patients presenting to a tertiary care centre. Study Design: Case series. Materials and Methods: The study was conducted at the Department of Oral and Maxillofacial Surgery, de'Montmorency College of Dentistry, Lahore, from January 2010 to December 2012. A total of sixteen patients were operated by using electrosurgical approach under general anaesthesia for surgical excision of generalized gingival enlargement. Results: All of the sixteen patients, 11 males and 5 females, showed excellent healing postoperatively without any recurrent gingival overgrowth. Discussion: To the best of our knowledge, the current study presents the largest case series of generalized gingival enlargement. Most of these cases were with massive disease due to lack of information of the study population about their disease, delay in referral by the general dental practitioners, painless and innocent nature of the problem. Early referral of such patients to tertiary care centers can prevent the patients from social and psychological embarrassment. Conclusion: Electrosurgical excision is an excellent surgical technique for management of generalized gingival enlargement. Moreover, cross comparative studies are required to establish some diagnostic and therapeutic standards for such patients. (author)

    The ability to measure gingival volume growth from dental casts would provide a valuable resource for periodontists. This problem is attractive from a computer vision standpoint due to the complexities of data acquisition, segmentation of gingival and tooth surfaces and boundaries, and extraction of features (such as tooth axes) to help solve the correspondence problem for multiple casts. In this paper, a structured light 3-D range finder is used to collect raw data. The most complicated subtask is that of detecting discontinuities such as the gingival margin. Discontinuity detection is hindered both by cast anomalies (such as bubbles and holes generated during the process of dental impression) and by the subtle nature of the discontinuities themselves. First, we discuss an approach to segmenting a dental cast into tooth and gingival units using depth and orientation discontinuities. The visible cast surface is reconstructed by obtaining the minimum of a parameterized functional. The first derivative of the energy functional (which corresponds to the Euler-Lagrange equation) is solved using the multigrid methods. both orientation and depth discontinuities are detected by adding a discrete discontinuity functional to the energy functional. The principal axes and boundaries of the teeth provide the information necessary to determine the region to be measured in estimating gingival growth. Finally, voxels corresponding to growth regions are counted to measure the target volume.

    Objective The aim of this study was to investigate the association among gingival enlargement (GE), periodontal conditions and socio-demographic characteristics in subjects undergoing fixed orthodontic treatment. Methods A sample of 330 patients undergoing fixed orthodontic treatment for at least 6 months were examined by a single calibrated examiner for plaque and gingival indexes, probing pocket depth, clinical attachment loss and gingival enlargement. Socio-economic background, orthodontic treatment duration and use of dental floss were assessed by oral interviews. Associations were assessed by means of unadjusted and adjusted Poisson's regression models. Results The presence of gingival bleeding (RR 1.01; 95% CI 1.00-1.01) and excess resin around brackets (RR 1.02; 95% CI 1.02-1.03) were associated with an increase in GE. No associations were found between socio-demographic characteristics and GE. Conclusion Proximal anterior gingival bleeding and excess resin around brackets are associated with higher levels of anterior gingival enlargement in subjects under orthodontic treatment.

    Human cultured gingival epithelial sheets were used as an autologous grafting material for regenerating gingival tissue in the maxillary left and mandibular right quadrants of a patient with chronic desquamative gingivitis. Six months post-surgery in both treated areas, there were gains in keratinized gingiva and no signs of gingival inflammation compared to presurgery. In the maxillary left quadrant, preoperative histopathologic findings revealed the epithelium was separated from the connective tissue and inflammatory cells were extensive. After grafting with the gingival epithelial sheets, inflammatory cells were decreased and separation between epithelium and connective tissue was not observed. The human cultured gingival epithelial sheets fabricated using tissue engineering technology showed significant promise for gingival augmentation in periodontal therapy.

    The efficacy of brushing the teeth of beagle dogs in a randomized, controlled, blinded study design using a clearly-defined brushing technique was evaluated for 4 brushing frequencies: brushing daily, brushing every other day, brushing weekly and brushing every other week, compared with no brushing in a control group of dogs. All dogs were fed a standard dry kibble diet during the study. Standard plaque, calculus, and gingivitis indices were used to score the teeth. A 'clean tooth' model was used. No gingival or non-gingival lacerations or other signs of injury to oral tissues were found at the end of the 28 day trial period. Brushing more frequently had greater effectiveness in retarding accumulation of plaque and calculus, and reducing the severity of pre-existing gingivitis. Brushing daily or every other day produced statistically significant improved results compared with brushing weekly or every other week. Based on the results of this study, daily brushing is recommended.

    Full Text Available Gingival fenestration defects are a rare phenomenon. Gingival fenestration means the exposure of the tooth due to loss of the overlying bone and gingiva. Though treatment of mucosal fenestration occurring in association with chronic periapical inflammation has been reported previously, the occurrence and treatment of gingival fenestration have not been documented in great detail. This report describes the occurrence of a gingival fenestration that developed secondarily to a gutka chewing habit. Treatment of the fenestration along with coverage of an adjacent recession defect in a single-step procedure using a pouch and tunnel technique is described.

  6. SOPROCARE - 450 nm wavelength detection tool for microbial plaque and gingival inflammation: a clinical study

    2014-02-01

    Gingivitis due to microbial plaque and calculus can lead over time if left untreated to advanced periodontal disease with non-physiological pocket formation. Removal of microbial plaque in the gingivitis stage typically achieves gingival health. The SOPROCARE camera system emits blue light at 450 nm wavelength using three blue diodes. The 450 nm wavelength is located in the non-ionizing, visible spectral wavelength region and thus is not dangerous. It is assumed that using the SOPROCARE camera in perio-mode inflamed gingiva can easily be observed and inflammation can be scored due to fluorescence from porphyrins in blood. The assumption is also that illumination of microbial plaque with blue light induces fluorescence due to the bacteria and porphyrin content of the plaque and thus can help to make microbial plaque and calculus visible. Aim of the study with 55 subjects was to evaluate the ability of the SOPROCARE fluorescence camera system to detect, visualize and allow scoring of microbial plaque in comparison to the Turesky modification of the Quigley and Hein plaque index. A second goal was to detect and score gingival inflammation and correlated the findings to the Silness and Löe gingival inflammation index. The study showed that scoring of microbial plaque as well as gingival inflammation levels similar to the established Turesky modified Quigley Hein index and the Silness and Löe gingival inflammation index can easily be done using the SOPROCARE fluorescence system in periomode. Linear regression fits between the different clinical indices and SOPROCARE scores in fluorescence perio-mode revealed the system's capacity for effective discrimination between scores.

    White-spot lesions (WSL) associated with orthodontic appliances are a cosmetic problem and increase risk for cavities. We characterized the microbiota of WSL, accounting for confounding due to gingivitis. Participants were 60 children with fixed appliances, aged between 10 and 19 yrs, half with WSL. Plaque samples were assayed by a 16S rRNA-based microarray (HOMIM) and by PCR. Mean gingival index was positively associated with WSL (p = 0.018). Taxa associated with WSL by microarray included Granulicatella elegans (p = 0.01), Veillonellaceae sp. HOT 155 (p gingivitis by microarray included: Gemella sanguinis (p = 0.002), Actinomyces sp. HOT 448 (p = 0.003), Prevotella cluster IV (p = 0.021), and Streptococcus sp. HOT 071/070 (p = 0.023); and levels of S. mutans (p = 0.02) and Bifidobacteriaceae (p = 0.012) by qPCR. Species’ associations with WSL were minimally changed with adjustment for gingivitis level. Partial least-squares discriminant analysis yielded good discrimination between children with and those without WSL. Granulicatella, Veillonellaceae and Bifidobacteriaceae, in addition to S. mutans and S. wiggsiae, were associated with the presence of WSL in adolescents undergoing orthodontic treatment. Many taxa showed a stronger association with gingivitis than with WSL. PMID:22837552

    Pregnancy gingivitis is an acute form of gingivitis that affects pregnant women, with a prevalence of 30%, possibly ranging up to 100%. Sometimes, pregnancy gingivitis shows a tendency toward a localized hyperplasia called gingival pyogenic granuloma. Pregnancy tumor is a benign gingival hyperplasia with the gingiva as the most commonly involved site, but rarely it involves almost the entire gingiva. A 22-year-old woman was referred to our clinic with a chief complaint of gingival swelling th...

    Oral rinses containing chemotherapeutic agents, such as cetylpyridinium chloride (CPC), can alleviate plaque-induced gingival infections, but how oral microbiota respond to these treatments in human population remains poorly understood. Via a double-blinded, randomised controlled trial of 91 subjects, the impact of CPC-containing oral rinses on supragingival plaque was investigated in experimental gingivitis, where the subjects, after a 21-day period of dental prophylaxis to achieve healthy gingivae, received either CPC rinses or water for 21 days. Within-subject temporal dynamics of plaque microbiota and symptoms of gingivitis were profiled via 16S ribosomal DNA gene pyrosequencing and assessment with the Mazza gingival index. Cetylpyridinium chloride conferred gingival benefits, as progression of gingival inflammation resulting from a lack of dental hygiene was significantly slower in the mouth rinse group than in the water group due to inhibition of 17 gingivitis-enriched bacterial genera. Tracking of plaque α and β diversity revealed that CPC treatment prevents acquisition of new taxa that would otherwise accumulate but maintains the original biodiversity of healthy plaques. Furthermore, CPC rinses reduced the size, local connectivity and microbiota-wide connectivity of the bacterial correlation network, particularly for nodes representing gingivitis-enriched taxa. The findings of this study provide mechanistic insights into the impact of oral rinses on the progression and maturation of dental plaque in the natural human population.

    The aim of this systematic review was to assess the gingival retraction methods in terms of the amount of gingival retraction achieved and changes observed in various clinical parameters: gingival index (GI), plaque index (PI), probing depth (PD), and attachment loss (AL). Data sources included three major databases, PubMed, CINAHL plus (Ebsco), and Cochrane, along with hand search. Search was made using the key terms in different permutations of gingival retraction* AND displacement method* OR technique* OR agents OR material* OR medicament*. The initial search results yielded 145 articles which were narrowed down to 10 articles using a strict eligibility criteria of including clinical trials or experimental studies on gingival retraction methods with the amount of tooth structure gained and assessment of clinical parameters as the outcomes conducted on human permanent teeth only. Gingival retraction was measured in 6/10 studies whereas the clinical parameters were assessed in 5/10 studies. The total number of teeth assessed in the 10 included studies was 400. The most common method used for gingival retraction was chemomechanical. The results were heterogeneous with regards to the outcome variables. No method seemed to be significantly superior to the other in terms of gingival retraction achieved. Clinical parameters were not significantly affected by the gingival retraction method. © 2016 by the American College of Prosthodontists.

    To compare the clinical, microbiological and metabonomic profiles of subjects with high and low levels of chronic gingival bleeding during a controlled oral hygiene regimen intervention including sequential phases of rigorous therapeutic oral hygiene followed by experimental gingivitis (EG). Two cohorts of qualified study subjects with differences in gingival bleeding on probing levels at their baseline clinical examination were entered into the study. These two cohorts were followed through three separate study phases including a 1-week baseline phase, a 2-week phase of rigorous oral hygiene including dental prophylaxis, and a 3-week EG phase of no oral hygiene to encourage relapse of gingivitis. The 58 subjects were assessed during each phase of the study for clinical presentation of gingivitis and concurrently had plaque sampled for real-time polymerase chain reaction (RTPCR) microbiological characterization and salivary lavage samples for 'systems biology' metabonomics assessment by 1H-NMR. Subjects presenting with different levels of gingival bleeding on probing when they entered the study responded differently to rigorous oral hygiene and EG. Specifically, the high bleeding cohort responded sluggishly to rigorous oral hygiene and exhibited markedly greater relapse to gingivitis during EG. RTPCR analysis showed changes in bacterial populations that were associated with study phases, particularly the increases in putative periodontal pathogens during EG. However, the microbiological profiles of high- and low-susceptibility gingival bleeding patients were largely similar. Metabonomic analysis likewise revealed significant changes in metabolite composition during study phases associated with differences in plaque toxicity, especially the short chain carboxylic acids propionate and n-butyrate, which tracked clinical changes in gingivitis severity. Systems analysis of metabonomic changes suggested differences between cohorts, although analysis to date has not

    Full Text Available We present a case of an 80-year-old male who was referred to the Department of Oral Medicine, School of Dental Medicine University of Zagreb, Croatia due to gingival ulcer which was present for eight days. Clinical examination has revealed exposed bone on the toothless alveolar ridge in the lower molar region on the right side of 0.8 cm in diameter. Otherwise, the patient was taking doxazosin due to urinary problems and ipatropium bromide due to respiratory problems. The patient wore a 6-year-old partial lower denture. He was initially treated with periodontal bandage (Resopack, HagenWerken, Germany for the first three days and was instructed not to wear the denture; however, no benefit could be seen. Therefore, we added a local corticosteroid (betamethasone and an oral antiseptic (chlorhexidine digluconate applied three times a day. After 3 weeks the lesion healed. A list of possible causative factors regarding gingival ulcers is included.

    2009-01-01

    Background Gingivitis has been linked to adverse pregnancy outcome (APO). Bacterial vaginosis (BV) has been associated with APO. We assessed if bacterial counts in BV is associated with gingivitis suggesting a systemic infectious susceptibilty. Methods Vaginal samples were collected from 180 women (mean age 29.4 years, SD ± 6.8, range: 18 to 46), and at least six months after delivery, and assessed by semi-quantitative DNA-DNA checkerboard hybridization assay (74 bacterial species). BV was defined by Gram stain (Nugent criteria). Gingivitis was defined as bleeding on probing at ≥ 20% of tooth sites. Results A Nugent score of 0–3 (normal vaginal microflora) was found in 83 women (46.1%), and a score of > 7 (BV) in 49 women (27.2%). Gingivitis was diagnosed in 114 women (63.3%). Women with a diagnosis of BV were more likely to have gingivitis (p = 0.01). Independent of gingival conditions, vaginal bacterial counts were higher (p gingivitis had higher counts of Prevotella bivia (p 1.0 × 104 cells) and a diagnosis of gingivitis was 3.9 for P. bivia (95% CI 1.5–5.7, p gingivitis in comparison to women with BV but not gingivitis. P. bivia and P. disiens may be of specific significance in a relationship between vaginal and gingival infections. PMID:19161595

    Bacteremia and systemic inflammatory markers are associated with periodontal and systemic diseases and may be linking mechanisms between these conditions. We hypothesized that in the development of gingival inflammation, systemic markers of inflammation and bacteremia would increase. To study the effect of bacteremia on systemic inflammatory markers, we recruited 80 subjects to participate in an experimental gingivitis study. Subjects were stratified based on gender, smoking and the number of bleeding sites and then randomized to one of two groups: control group (n = 40) or experimental gingivitis group (n = 40). Subjects in the control group conducted an oral hygiene regimen: brushing twice daily with a regular sodium fluoride cavity protection dentifrice and a standard manual toothbrush, flossing twice daily, and mouth rinsing with an anti-cavity fluoride rinse once daily. The experimental group stopped brushing and flossing, and used only the fluoride anti-cavity mouth rinse for 21 d. Seventy-nine of 80 subjects were evaluable. One subject in the control group was excluded from the results due to antibiotic use during the study. Our data showed the experimental gingivitis group exhibited a significant (p gingival inflammatory indices relative to baseline and the control group but a decrease in bacteremia and soluble intercellular adhesion molecule-1 levels vs. baseline. Bacteremia was negatively correlated with gingival inflammatory indices and soluble intercellular adhesion molecule-1 levels in the experimental gingivitis group, thus negating our hypothesis. We conclude that there are marked differences in systemic cytokine levels over the course of short-term experimentally induced gingivitis and further conclude that a long-term periodontitis study must be considered to address mechanisms whereby oral diseases may affect systemic diseases. © 2015 John Wiley & Sons A/S.

  15. Microbiota and Metatranscriptome Changes Accompanying the Onset of Gingivitis

    Science.gov (United States)

    2018-01-01

    ABSTRACT Over half of adults experience gingivitis, a mild yet treatable form of periodontal disease caused by the overgrowth of oral microbes. Left untreated, gingivitis can progress to a more severe and irreversible disease, most commonly chronic periodontitis. While periodontal diseases are associated with a shift in the oral microbiota composition, it remains unclear how this shift impacts microbiota function early in disease progression. Here, we analyzed the transition from health to gingivitis through both 16S v4-v5 rRNA amplicon and metatranscriptome sequencing of subgingival plaque samples from individuals undergoing an experimental gingivitis treatment. Beta-diversity analysis of 16S rRNA reveals that samples cluster based on disease severity and patient but not by oral hygiene status. Significant shifts in the abundance of several genera occurred during disease transition, suggesting a dysbiosis due to development of gingivitis. Comparing taxonomic abundance with transcriptomic activity revealed concordance of bacterial diversity composition between the two quantification assays in samples originating from both healthy and diseased teeth. Metatranscriptome sequencing analysis indicates that during the early stages of transition to gingivitis, a number of virulence-related transcripts were significantly differentially expressed in individual and across pooled patient samples. Upregulated genes include those involved in proteolytic and nucleolytic processes, while expression levels of those involved in surface structure assembly and other general virulence functions leading to colonization or adaptation within the host are more dynamic. These findings help characterize the transition from health to periodontal disease and identify genes associated with early disease. PMID:29666288

    To determine the occurrence of smile line and maxillary tooth shape in the Saudi Arabian subpopulation, and to estimate the association between these parameters with gingival biotype. On the fulfillment of selection criteria, total 315 patients belong to Saudi Arabian ethnic group were randomly selected. Two frontal photographs of the patients were acquired. The tooth morphology, gingival angle, and smile line classification were determined with ImageJ image analyzing software. The gingival biotype was assessed by probe transparency method. The obtained data were analyzed with SPSS 19 (IBM Corporation, New York, USA) software to determine the frequency and association between other parameters and gingival biotype. Among the clinical parameters evaluated, the tapering tooth morphology (56.8%), thick gingival biotype (53%), and average smile line (57.5%) was more prevalent. The statistically significant association was found between thick gingival biotype and the square tooth, high smile line. The high gingival angle was associated with thin gingival biotype. The study results indicate the existence of an association between tooth shape, smile line, and gingival angle with gingival biotype.

    Head trauma injury due to impact by a flying golf ball is one of the most severe possible injury accidents on the golf course. Numerical simulations based on the finite element method are presented to investigate head injury in children due to impact by a flying golf ball. The stress and energy flow patterns in a head model during the golf ball impact are computed for various combinations of striking speed, falling angle of the golf ball before impact, and impact location. It is found that a child is more prone to head injury due to golf ball impact on the frontal and side/temporal areas. The simulated results are found to conform to the clinical reports on children's head injuries from flying golf balls.

    Each year in the United States, an estimated 800 to 1,400 people are murdered at work, and an unknown number of nonfatal injuries due to workplace violence occur. Based on Ohio's workers' compensation claims from 1983 through 1985, police officers, gasoline service station employees, employees of the real estate industry, and hotel/motel employees were found to be at the highest risk for occupational violent crime (OVC) injury and death. Grocery store employees, specifically those working in convenience food stores, and employees of the real estate industry had the most reported rapes. Four previously unidentified industries at increased risk of employee victimization were described. Identification of industries and occupations at high risk for crime victimization provides the opportunity to focus preventive strategies to promote employee safety and security in the workplace.

    Full Text Available Introduction: About 0.1% of the population suffers from necrotizing ulcerative gingivitis, a disease of rapid progression and acute manifestation, which may progress to necrotizing ulcerative periodontitis and eventually to bone sequestration and loss of gingival tissue. Case report: A 21-year-old female patient undergoing orthodontic treatment for six months, diagnosed with necrotizing ulcerative gingivitis due to acute pain in the gingival tissue, spontaneous bleeding, halitosis and abundant plaque. The treatment was conservative and effective, obtaining total remission of the lesion after seven days and three months of postoperative follow-up. Conclusion: Today there are no epidemiological or clinical reports that support the relationship of necrotizing ulcerative gingivitis and orthodontic treatment. Prevention is critical to the success of the treatment, which is why the dentist should recognize the clinical features of necrotizing ulcerative gingivitis to raise awareness of its risks in the orthodontic patient.

The presentation aims to show biomechanical considerations in relation to movement of teeth with gingival...... by moving the root back in the alveolus. The tooth movement is accompanied by bone gain and thus increase the success rate for soft tissue augmentation. The choice of biomechanical system influences the treatment outcome.

    Full Text Available Drug-induced gingival overgrowth is frequently associated with three particular drugs: phenytoin, cyclosporin, and nifedipine. As gingival enlargement develops, it affects the normal oral hygiene practice and may interfere with masticatory functions. The awareness in the medical community about this possible side effect of nifedipine is less when compared to the effects of phenytoin and cyclosporin. The frequency of gingival enlargement associated with chronic nifedipine therapy remains controversial. Within the group of patients that develop this unwanted effect, there appears to be variability in the extent and severity of the gingival changes. Although gingival inflammation is considered a primary requisite in their development, few cases with minimal or no plaque induced gingival inflammation have also been reported. A case report of gingival overgrowth induced by nifedipine in a patient with good oral hygiene and its nonsurgical management with drug substitution is discussed in this case report.

    Full Text Available Pregnancy gingivitis is an acute form of gingivitis that affects pregnant women, with a prevalence of 30%, possibly ranging up to 100%. Sometimes, pregnancy gingivitis shows a tendency toward a localized hyperplasia called gingival pyogenic granuloma. Pregnancy tumor is a benign gingival hyperplasia with the gingiva as the most commonly involved site, but rarely it involves almost the entire gingiva. A 22-year-old woman was referred to our clinic with a chief complaint of gingival swelling that had lasted for 2 days. The lesions progressed rapidly and extensively, and almost all the gingiva was involved a week later. Generalized erythema, edema, hyperplasia, a hemorrhagic tendency, and several typical hemangiomatous masses were noted. Pregnancy was denied by the patient at the first and second visits, but was confirmed 2 weeks after the primary visit. The patient was given oral hygiene instructions. She recovered well, and the mass gradually regressed and had disappeared completely at the end of 12 weeks of pregnancy, without recurrence. The gingival lesions were finally diagnosed as multiple gingival pregnancy tumors. The patient delivered a healthy infant. An extensive and rapid growth of gingival pregnancy tumors during the early first month of pregnancy is a rare occurrence that is not familiar to dentists, gynecologists, and obstetricians. Those practitioners engaged in oral medicine and periodontology, primary care obstetrics, and gynecology should be aware of such gingival lesions to avoid misdiagnosis and overtreatment.

    To analyse the microbiome composition of health and gingivitis in Chinese undergraduates with high-throughput sequencing. Sequencing of 16S rRNA gene amplicons was performed with the MiSeq system to compare subgingival bacterial communities from 54 subjects with gingivitis and 12 periodontally healthy controls. A total of 1,967,372 sequences representing 14 phyla, 104 genera, and 96 species were detected. Analysis of similarities (Anosim) test and Principal Component Analysis (PCA) showed significantly different community profiles between the health control and the subjects with gingivitis. Alpha-diversity metrics were significantly higher in the subgingival plaque of the subjects with gingivitis compared with that of the healthy control. Overall, the relative abundance of 35 genera and 46 species were significantly different between the two groups, among them 28 genera and 45 species showed higher relative abundance in the subjects with gingivitis, whereas seven genera and one species showed a higher relative abundance in the healthy control. The genera Porphyromonas, Treponema, and Tannerella showed higher relative abundance in the subjects with gingivitis, while the genera Capnocytophaga showed higher proportions in health controls. Porphyromonas gingivalis, Prevotella intermedia and Porphyromonas endodontalis had higher relative abundance in gingivitis. Among them, Porphyromonas gingivalis was most abundant. Our results revealed significantly different microbial community composition and structures of subgingival plaque between subjects with gingivitis and healthy controls. Subjects with gingivitis showed greater taxonomic diversity compared with periodontally healthy subjects. The proportion of Porphyromonas, especially Porphyromonas gingivalis, may be associated with gingivitis subjects aged between 18 and 21 years old in China. Adults with gingivitis in this age group may have a higher risk of developing periodontitis.

    Full Text Available Background: Actinobacillus actinomycetemcomitans (Aa serotype B has been associated with aggressive periodontitis. Gingival epithelial cell is exquisitely sensitive to the toxin and may lead to the epithel protective barrier disruption. Experimental models show that minocycline is not related to it’s antimicrobial effect and protection against neuron cell apoptosis of a number experimental models of brain injury and Parkinson’s disease. Purpose: This study, examined antioxidant effect of minocycline to inhibit apoptosis of gingival epithelium induced crude toxin bacteria Aa serotype B in mice. Methods: Thirty adult mice strain Swiss Webster (balb C were divided randomly into three groups: control group (group A, toxin group (group B and toxin and minocycline group (group C. The mice were taken at 24 hours after application, and then the tissue sections of gingival epithelium were stained with tunnel assay and immunohistochemistry. Result: Treatment with these toxin induced apoptosis of gingival epithelium and was associated with DNA fragmentation and reduced gluthatione (GSH. Minocycline 100 nM significantly increased GSH and reduced apoptosis (p < 0.05. Minocycline provides antioxidant effect against citotoxicity of bacteria Aa serotipe B. Conclusion: Nanomolar concentration of minocycline potential as new therapeutic agent to prevent progressivity of aggressiveness of periodontitis.

    Current knowledge of the microbial composition of dental plaque in early gingivitis is based largely on microscopy and cultural methods, which do not provide a comprehensive description of oral microbial communities. This study used 454-pyrosequencing of the V1–V3 region of 16S rRNA genes (approximately 500 bp), and bacterial culture, to characterize the composition of plaque during the transition from periodontal health to gingivitis. A total of 20 healthy volunteers abstained from oral hygiene for two weeks, allowing plaque to accumulate and gingivitis to develop. Plaque samples were analyzed at baseline, and after one and two weeks. In addition, plaque samples from 20 chronic periodontitis patients were analyzed for cross-sectional comparison to the experimental gingivitis cohort. All of the healthy volunteers developed gingivitis after two weeks. Pyrosequencing yielded a final total of 344 267 sequences after filtering, with a mean length of 354 bases, that were clustered into an average of 299 species-level Operational Taxonomic Units (OTUs) per sample. Principal coordinates analysis (PCoA) plots revealed significant shifts in the bacterial community structure of plaque as gingivitis was induced, and community diversity increased significantly after two weeks. Changes in the relative abundance of OTUs during the transition from health to gingivitis were correlated to bleeding on probing (BoP) scores and resulted in the identification of new health- and gingivitis-associated taxa. Comparison of the healthy volunteers to the periodontitis patients also confirmed the association of a number of putative periodontal pathogens with chronic periodontitis. Taxa associated with gingivitis included Fusobacterium nucleatum subsp. polymorphum, Lachnospiraceae [G-2] sp. HOT100, Lautropia sp. HOTA94, and Prevotella oulorum, whilst Rothia dentocariosa was associated with periodontal health. Further study of these taxa is warranted and may lead to new therapeutic approaches

    Current knowledge of the microbial composition of dental plaque in early gingivitis is based largely on microscopy and cultural methods, which do not provide a comprehensive description of oral microbial communities. This study used 454-pyrosequencing of the V1-V3 region of 16S rRNA genes (approximately 500 bp), and bacterial culture, to characterize the composition of plaque during the transition from periodontal health to gingivitis. A total of 20 healthy volunteers abstained from oral hygiene for two weeks, allowing plaque to accumulate and gingivitis to develop. Plaque samples were analyzed at baseline, and after one and two weeks. In addition, plaque samples from 20 chronic periodontitis patients were analyzed for cross-sectional comparison to the experimental gingivitis cohort. All of the healthy volunteers developed gingivitis after two weeks. Pyrosequencing yielded a final total of 344,267 sequences after filtering, with a mean length of 354 bases, that were clustered into an average of 299 species-level Operational Taxonomic Units (OTUs) per sample. Principal coordinates analysis (PCoA) plots revealed significant shifts in the bacterial community structure of plaque as gingivitis was induced, and community diversity increased significantly after two weeks. Changes in the relative abundance of OTUs during the transition from health to gingivitis were correlated to bleeding on probing (BoP) scores and resulted in the identification of new health- and gingivitis-associated taxa. Comparison of the healthy volunteers to the periodontitis patients also confirmed the association of a number of putative periodontal pathogens with chronic periodontitis. Taxa associated with gingivitis included Fusobacterium nucleatum subsp. polymorphum, Lachnospiraceae [G-2] sp. HOT100, Lautropia sp. HOTA94, and Prevotella oulorum, whilst Rothia dentocariosa was associated with periodontal health. Further study of these taxa is warranted and may lead to new therapeutic approaches

    In this cross-sectional study, risk and potentially causative factors of gingival recession were examined and their relationship to apical migration of the gingival margin evaluated. Thirty eight patients (18-60 years), displaying one or more sites with gingival recession but without any significant periodontal disease participated. A total of 28 parameters were evaluated in both 'test' teeth (50 teeth with gingival recession) and 'control' teeth (50 contralateral teeth). The results revealed that gingival margin recession was associated with both high inflammatory and plaque scores, with decreased widths of keratinized and attached gingiva and with the subjects' toothbrush bristle hardness.

    The presence of any age-related differences in gingival pigmentation associated with smoking, particularly in a young population, remains to be fully investigated. The purpose of this study was to determine the age-related differences in smoking gingival pigmentation. Gingival pigmentation was analyzed using the gingival melanosis record (GMR) and Hedin's classification with frontal oral photographs taken at 16 dental offices in Japan. Participants were categorized into 10-year age groups, and their baseline photographs were compared. In addition, to evaluate the effect of smoking cessation on gingival pigmentation, subjects were divided into a former smoker group (stopped smoking) and current smoker group. A total of 259 patients 19 to 79 years of age were analyzed. People in their 30s showed the most widespread gingival pigmentation. In addition, subjects in their 20s showed a weak effect of smoking cessation on gingival pigmentation. These findings suggested that the gingival pigmentation induced by smoking was more remarkable in young people than in middle-aged people. This information may be useful for anti-smoking education, especially among young populations with a high affinity for smoking.

    Gingival wound healing comprises a series of sequential responses that allow the closure of breaches in the masticatory mucosa. This process is of critical importance to prevent the invasion of microbes or other agents into tissues, avoiding the establishment of a chronic infection. Wound healing may also play an important role during cell and tissue reaction to long-term injury, as it may occur during inflammatory responses and cancer. Recent experimental data have shown that gingival wound healing is severely affected by the aging process. These defects may alter distinct phases of the wound-healing process, including epithelial migration, granulation tissue formation, and tissue remodeling. The cellular and molecular defects that may explain these deficiencies include several biological responses such as an increased inflammatory response, altered integrin signaling, reduced growth factor activity, decreased cell proliferation, diminished angiogenesis, reduced collagen synthesis, augmented collagen remodeling, and deterioration of the proliferative and differentiation potential of stem cells. In this review, we explore the cellular and molecular basis of these defects and their possible clinical implications. © International & American Associations for Dental Research 2014.

    The Occupational Safety and Health Administration (OSHA) and the Bureau of Labor Statistics (BLS) provide the Survey of Occupational Illness and Injury (SOII) statistics from 1992 to 2006, which is often used to measure the rate of injuries and illness in industry. The present system of gathering and classifying this data was implemented in 1992 with minor changes in 2002. It is hoped that using these statistics to measure safety progress and determine patterns of injury will guide further improvements in chemical safety. Recognizing such factors as what chemicals most frequently cause injury can help to focus safety efforts regarding that chemical. Factors such as what part of the body is most commonly affected by particular chemicals can lead to improved personnel protection practices. This paper provides a detailed analysis of injuries due to chemicals using OSHA's SOII data, which offers valuable insight into measures that should be taken to reduce injuries due to chemicals.

    This aim of this study was to develop and assess a technique that could be used to assess accurately the gingival volume changes seen in drug-induced gingival overgrowth by the analysis of data obtained from an entire gingival surface by means of three-dimensional imaging. Stone dental models of patients before and after gingivectomy procedures were digitized with a laser scanner and then regenerated as computer models constructed from the acquired three-dimensional co-ordinate data. A comparison of superposed "before" and "after" surfaces was undertaken to assess and accurately quantify changes in gingival contour. The mean vertical tissue reduction varied from 1.58 to 2.56 mm in the four study subjects and individual differences are shown. The maximum thickness of removed buccal gingival overgrowth was found to range between 1.20 and 3.40 mm. The volume of tissue removed from each inter-dental papilla ranged from 4.2 to 46.1 mm3 and the mean volume of the papilla removed from each subject+/-SD values was 24.8+/-13.1 mm3. This method will measure changes in gingival tissues to within 60 microm in one plane, making it ideal for the assessment of longitudinal changes in gingival contour as seen in the development of gingival overgrowth, its recurrence after surgery or the changes in volume brought about by surgery.

    Full Text Available The prevalence of obesity has increased drastically in most developed countries. Many studies showed that obesity associated with oral diseases, especially periodontal disease. A recent study showed the relation between WC and periodontal disease counted by gingival index (GI. However, studies regarding the mechanism of the relationship between obesity and periodontal disease are still quite a few, whereas many studies conducted suggested that obesity was a medical problem. The study was aimed to know and assess the gingival condition of obese people who visited the Dental Polyclinic of Hasan Sadikin Hospital. The type of this study was descriptive with the survey technique. A total of 54 people consisted of 35 female and 19 male patients with the age range of 20-49 years old, and not using any dental prosthesis or orthodontic appliance. This study was using a questionnaire and clinical examination to assess the condition of the gingival using the Löe and Silness Gingival index (GI. Examination of obesity conducted by measuring the waist circumference with criteria from WHO. The average value of the gingival index was 1.22. Meanwhile, the average value of the waist circumference (WC was 95.89 cm and 107.74 cm consecutively for female and male. The majority of obese patients suffered moderate gingivitis.

    This paper describes a unique case of a fatal tiger attack in the wild. In the present case, a tiger fatally mauled a 34-year-old female with its claws, instead of the usual mechanism of killing by the bite injury to the neck. The autopsy revealed multiple fatal and non-fatal injuries caused by the tiger claws. The characteristic injuries due to the tooth impacts were absent as the teeth of the offending tiger were either fallen or non-functional. To the best of our knowledge, probably this rare case would be the first reported human fatality due to the tiger claw injuries in the world. The purpose of the present article is to highlight the fatal injuries due to the tiger claws, as the claw-induced fatal injuries in a tiger attack are not reported in the medico-legal literature. Moreover, this report would be an illustrative one for differentiation between the fatal injuries due to the claws and tooth impacts in a tiger attack. Furthermore, the present report establishes the importance of the tiger claws as a source of fatal injuries in a tiger attack. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available The inflammatory enlargement is clinically called hyperthropic gingivitis or gingival hyperplasia and generally related to local or systemic factors. They could be edematous or fibrous. The former is treated by scaling, but the latter that could not be treated by scaling only has to be removed by gingivectomy. There are some cases of gingivectomy resulting in recurrences. The writer wanted to find out the cause of the recurrences. The types of research were clinical and laboratories observational studies. The criteria of sample were: male or female patient who came to periodontal clinic of Faculty of Dentistry Airlangga University. They were diagnosed gingivitis hyperplasia; had no systemic diseases; did not wear the orthodontic appliances, prosthesis, and crown and bridge; do not smoke. The indicated teeth to be observed were the labial side of maxillary front teeth. The teeth had score hyperplastic index (HI = 2 at the 2nd weeks after scaling. There were 7 samples taken selectively. The results of the studies were based on the comparison of 1 hyperplasia index (HI; 2 the number and percentage of monosite and leucocytes from white blood impedance coutl (WIC and white blood optical coutl (WOC; 3 plaque Index; and 4 gingival index. The result of gingivectomy was reevaluated on the 30th, 45th, 60th, 90th day. The research concluded that the number of monosite was normal, but the dental plaque still accumulated and eventually caused the recurrences of the inflammation.

    Full Text Available Gingival fibromatosis with hypertrichosis syndrome is an extremely rare genetic condition characterized by profound overgrowth of hair and gums, as well as other variable features. Gingival fibromatosis is characterized by a large increase in the gingival dimension which extends above the dental crowns, covering them partially or completely. They were found to have a genetic origin, may also occur in isolation or be part of a syndrome, or acquired origin, due to specific drugs administered systemically. Congenital generalized hypertrichosis is a heterogeneous group of diseases with continuing excessive growth of terminal hair without androgenic stimulation. It has informally been called werewolf syndrome because the appearance is similar to that of a werewolf. Various syndromes have been associated with these features such as epilepsy, mental retardation, cardiomegaly, or osteochondrodysplasia. As so far very few cases have been reported in literature, we are reporting a series of three cases with management of the same. The excess gingival tissues, in these cases, were removed by conventional gingivectomy under general anesthesia. The postoperative result was uneventful and the patient's appearance improved significantly. Good esthetic result was achieved to allow patient to practice oral hygiene measures. Though this is not a serious condition clinically, psychosocial trauma cannot be neglected owing to the cosmetic disfigurement it produces.

  2. Aged blood factors decrease cellular responses associated with delayed gingival wound repair.

    Full Text Available Aging is a gradual biological process characterized by a decrease in cell and organism functions. Gingival wound healing is one of the impaired processes found in old rats. Here, we studied the in vivo wound healing process using a gingival repair rat model and an in vitro model using human gingival fibroblast for cellular responses associated to wound healing. To do that, we evaluated cell proliferation of both epithelial and connective tissue cells in gingival wounds and found decreased of Ki67 nuclear staining in old rats when compared to their young counterparts. We next evaluated cellular responses of primary gingival fibroblast obtained from young subjects in the presence human blood serum of individuals of different ages. Eighteen to sixty five years old masculine donors were classified into 3 groups: "young" from 18 to 22 years old, "middle-aged" from 30 to 48 years old and "aged" over 50 years old. Cell proliferation, measured through immunofluorescence for Ki67 and flow cytometry for DNA content, was decreased when middle-aged and aged serum was added to gingival fibroblast compared to young serum. Myofibroblastic differentiation, measured through alpha-smooth muscle actin (α-SMA, was stimulated with young but not middle-aged or aged serum both the protein levels and incorporation of α-SMA into actin stress fibers. High levels of PDGF, VEGF, IL-6R were detected in blood serum from young subjects when compared to middle-aged and aged donors. In addition, the pro-inflammatory cytokines MCP-1 and TNF were increased in the serum of aged donors. In old rat wound there is an increased of staining for TNF compared to young wound. Moreover, healthy gingiva (non injury shows less staining compared to a wound site, suggesting a role in wound healing. Moreover, serum from middle-aged and aged donors was able to stimulate cellular senescence in young cells as determined by the expression of senescence associated beta-galactosidase and histone H2

    The aim of the present study was to determine gingival crevicular fluid (GCF) levels of monocyte chemotactic protein-1 (MCP-1), regulated on activation, normal T-cell expressed and secreted protein (RANTES) and macrophage migration inhibitory factor (MIF) in metabolic syndrome patients with gingivitis. Twenty metabolic syndrome patients with gingivitis (MSG), 20 MetS patients with clinically healthy periodontium (MSH), 20 systemically healthy subjects with gingivitis and 20 subjects who were both systemically and periodontally healthy were included. Periodontal and systemical parameters were recorded. GCF MCP-1, RANTES and MIF levels were assayed by enzyme-linked immunosorbent assay method. MSG and MSH groups had elevated blood pressure, triglyceride, waist circumference and fasting glucose values in comparison to gingivitis and healthy groups (Pgingivitis groups when compared to those of the MSH and healthy groups (Pgingivitis group had higher MCP-1, RANTES and MIF levels compared to the healthy group (P=0.011, P=0.0001, P=0.011 respectively). The RANTES level of MSG group was significantly higher than those of the gingivitis group (P=0.01), but MCP-1 and MIF levels were similar in the MSG and gingivitis groups (P>0.05). Elevated levels of GCF RANTES in MetS patients with gingivitis might associate with the presence of increased gingival inflammation by MetS. Low-grade systemic inflammation associated with MetS and adipose tissue-derived RANTES might lead to altered GCF RANTES levels in the presence of gingival inflammation. Copyright © 2016.

    To describe the ultrastructural features of hereditary gingival fibromatosis (HGF) in affected family members and compare microscopic findings with normal gingival (NG) tissue. Gingival tissue samples from nine patients with HGF from five unrelated families were evaluated by transmission electron microscopy. Nine NG tissue samples were used for comparison. Areas containing collagen fibrils forming loops and folds were observed in both groups, whereas oxytalan fibers were frequently identified in the HGF group. The diameter of collagen fibrils and the interfibrillar space among them were more uniform in the NG group than in the HGF group. Fibroblasts were the most common cells found in both the HGF and NG groups and exhibited enlarged, rough endoplasmic reticulum, mitochondria with well-preserved crests, conspicuous nucleoli, and euchromatic chromatin. Other cells, such as mast cells, plasma cells, and macrophages, were also observed. HGF tissues had ultrastructural characteristics that were very similar to those of NG tissues. Oxytalan fibers were observed more frequently in the HGF samples than in the NG samples. Other studies of HGF in patients from different families should be performed to better understand the pathogenesis of this hereditary condition. Copyright © 2016 Elsevier Inc. All rights reserved.

    The aim of this study was to determine which smile asymmetries were less esthetic, dental or gingival. Laypeople (297), generalists (223), prosthodontists (50) and orthodontists (49), evaluated the esthetics of digitally-modified images taken from the same frontal intra-oral photograph, using the same lips, simulating upper maxillary midline shift, occlusal plane inclination, asymmetric incisal edge and asymmetric gingival migration. The images were later paired into 3 groups. The only ones considered esthetic were the asymmetric incisal edge of the 0.5 mm shorter upper central incisor and the asymmetric gingival migration (2 mm) of the upper central incisor. In the paired images, upper maxillary midline shift vs. occlusal plane inclination, the former was rated less esthetic, while in the asymmetric incisal edge vs. asymmetric gingival migration pair, the latter was considered to be less esthetic. Laypeople and generalists consider smiles more attractive. The only images considered esthetic were the asymmetric incisal edge of the central incisor shorter by 0.5 mm and the 2 mm asymmetric gingival migration of the upper central incisor. In the horizontal plane (maxillary midline shift vs. occlusal plane cant), the dental asymmetries were considered less esthetic than the gingival asymmetries. However, in the vertical plane (asymmetric incisal edge vs. asymmetric gingival migration) the opposite was recorded. Copyright © 2015 CEO. Published by Elsevier Masson SAS. All rights reserved.

    Over half of adults experience gingivitis, a mild yet treatable form of periodontal disease caused by the overgrowth of oral microbes. Left untreated, gingivitis can progress to a more severe and irreversible disease, most commonly chronic periodontitis. While periodontal diseases are associated with a shift in the oral microbiota composition, it remains unclear how this shift impacts microbiota function early in disease progression. Here, we analyzed the transition from health to gingivitis through both 16S v4-v5 rRNA amplicon and metatranscriptome sequencing of subgingival plaque samples from individuals undergoing an experimental gingivitis treatment. Beta-diversity analysis of 16S rRNA reveals that samples cluster based on disease severity and patient but not by oral hygiene status. Significant shifts in the abundance of several genera occurred during disease transition, suggesting a dysbiosis due to development of gingivitis. Comparing taxonomic abundance with transcriptomic activity revealed concordance of bacterial diversity composition between the two quantification assays in samples originating from both healthy and diseased teeth. Metatranscriptome sequencing analysis indicates that during the early stages of transition to gingivitis, a number of virulence-related transcripts were significantly differentially expressed in individual and across pooled patient samples. Upregulated genes include those involved in proteolytic and nucleolytic processes, while expression levels of those involved in surface structure assembly and other general virulence functions leading to colonization or adaptation within the host are more dynamic. These findings help characterize the transition from health to periodontal disease and identify genes associated with early disease. IMPORTANCE Although more than 50% of adults have some form of periodontal disease, there remains a significant gap in our understanding of its underlying cause. We initiated this study in order to

    Salivary biomarkers are potentially important for determining the presence, risk, and progression of periodontal disease. However, clinical translation of biomarker technology from lab to chairside requires studies that identify biomarkers associated with the transitional phase between health and periodontal disease (i.e., gingivitis). Eighty participants (40 with gingivitis, 40 healthy) provided saliva at baseline and 7 to 30 days later. An additional sample was collected from gingivitis participants 10 to 30 days after dental prophylaxis. Clinical parameters of gingival disease were recorded at baseline and the final visit. Salivary concentrations of interleukin (IL)-1β, IL-6, matrix metalloproteinase (MMP)-8, macrophage inflammatory protein (MIP)-1α, and prostaglandin E2 (PGE2) were measured. Clinical features of health and gingivitis were stable at both baseline visits. Participants with gingivitis demonstrated significantly higher bleeding on probing (BOP), plaque index (PI), and gingival index (GI) (P ≤0.002) and a significant drop in BOP, PI, and GI post-treatment (P ≤0.001). Concentrations of MIP-1α and PGE2 were significantly higher (2.8 times) in the gingivitis group than the healthy group (P ≤0.02). After dental prophylaxis, mean biomarker concentrations did not decrease significantly from baseline in the gingivitis group, although concentrations of IL-1β, IL-6, and MMP-8 approached healthy levels, whereas MIP-1α and PGE2 concentrations remained significantly higher than in the healthy group (P ≤0.04). Odds ratio analyses showed that PGE2 concentrations, alone and in combination with MIP-1α, readily discriminated gingivitis from health. Salivary PGE2 and MIP-1α discriminate gingivitis from health, and patients with gingivitis who return to clinical health continue to produce inflammatory mediators for weeks after dental prophylaxis.

    The present study aimed to morphologically examine the gingival microvascular network using a microvascular resin cast (MRC) technique, and to investigate how inflammatory disease functionally affects gingival microcirculation using laser Doppler flowmetry (LDF). We used four beagle dogs with healthy periodontal tissue as experimental animals. To cause periodontal inflammation, dental floss was placed around the cervical neck portions of the right premolars. The unmanipulated left premolars served as controls, and received plaque control every 7 days. After 90 days, gingivitis was induced in the experimental side, while the control side maintained healthy gingiva. To perform morphological examinations, we used an MRC method involving the injection of low-viscosity synthetic resin into the blood vessels, leading to peripheral soft-tissue dissolution and permitting observation of the bone, teeth, and vascular cast. Gingival blood flow was estimated using an LDF meter. The control gingival vasculature showed hairpin-loop-like networks along the tooth surface. The blood vessels had diameters of 20-40 μm and were regularly arranged around the cervical portion. On the other hand, the vasculature in the experimental group was twisted and gathered into spiral forms, with blood vessels that had uneven surfaces and smaller diameters of 8-10 μm. LDF revealed reduced gingival blood flow in the group with experimentally induced gingivitis compared to controls. The actual measurements of gingival blood flow by LDF were in agreement with the alterations that would be expected based on the gingivitis-induced morphological alterations observed with the MRC technique.

    To investigate the influence of salivary osmolality on the occurrence of gingivitis in children with cerebral palsy (CP). A total of 82 children with spastic CP were included in this cross-sectional study. Oral motor performance and gingival conditions were evaluated. Unstimulated saliva was collected using cotton swabs, and salivary osmolality was measured using a freezing point depression osmometer. Spearman's coefficient, receiver operating characteristic (ROC), and multiple logistic regression analyses were performed. Strong correlation (r > 0.7) was determined among salivary osmolality, salivary flow rate, visible plaque, dental calculus, and the occurrence of gingivitis. The area under the ROC to predict the influence of salivary osmolality on the occurrence of gingivitis was 0.88 (95% CI 0.81-0.96; P gingivitis was 22.5%, whereas for the group presenting osmolality >84.5 mOsm/kgH 2 O, the proportion of children with gingivitis was 77.5%. Salivary osmolality above 84.5 increased the likelihood of gingivitis fivefold, whereas each additional 0.1 mL of salivary flow reduced the likelihood of gingivitis by 97%. Gingivitis occurs more frequently in children with CP showing increased values of salivary osmolality. © 2016 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Clinicians are often intrigued by the varied manifestations of the gingival tissue. Gingival overgrowth is a common clinical finding and most of them represent a reactive hyperplasia as a direct result of plaque-related inflammatory gingival disease. These types of growth generally respond to good plaque control, removal of the causative irritants, and conservative tissue management. This case series highlights three different cases of localized gingival overgrowth and its management with emphasis on the importance of patient awareness and motivation.

    Gingival cyst of newborn is an oral mucosal lesion of transient nature. Although it is very common lesion within 3 to 6 weeks of birth, it is very rare to visualize the lesion thereafter. Presented here is a case report of gingival cyst, which was visible just after 15 days of birth. Clinical diagnoses of these conditions are important in order to avoid unnecessary therapeutic procedure and provide suitable information to parents about the nature of the lesion.

    Full Text Available Background: A defined role for reactive oxygen species (ROS in the tissue destruction that characterizes periodontitis has been described. Protein carbonyl (PC is the most widely used biomarker for oxidative damage to proteins, and reflects cellular damage induced by multiple forms of ROS. The purpose of this study is to determine the presence of PC in gingival crevicular fluid (GCF in healthy, gingivitis, and chronic periodontitis (CP subjects and to find an association, if any. Materials and Methods: A total number of 75 subjects (38 males and 37 females were selected based on their clinical parameters into three groups: Group 1 (25 healthy subjects, Group 2 (25 gingivitis subjects, and Group 3 (25 CP subjects. GCF samples were collected to estimate the levels of PC. Results: The PC concentration in GCF was highest in subjects with CP as compared to gingivitis and healthy subjects and a significant association was observed between GCF PC levels and all periodontal parameters. Conclusion: There was an increase in PC levels in GCF as the disease process progressed from healthy to gingivitis and CP, suggesting a role for increased oxidative stress in CP.

    Full Text Available Background: Deficiency of Co-Q10 has been found to be responsible for periodontal destruction; therefore, this study was undertaken to evaluate the anti-gingivitis effect of Co-Q10 on plaque induced gingivitis. Materials and Methods: Thirty subjects with plaque induced gingivitis were enrolled in a split mouth randomized controlled trial. For each subject, scaling was randomly performed for any two quadrants, followed by the topical application of Co-Q10 randomly in a previously scaled and as an unscaled quadrant for a period of 28 days. Four treatment options were planned: option A: scaling only; option B: Co-Q10 along with scaling; option C: Co-Q10. Results: Marked reduction in gingival, bleeding, and plaque scores were recorded at the sites where C0-Q10 was applied. Mean±S.D of aforementioned periodontal parameters at 28th day showed significant reduction for option A, B, and C when compared with baseline. Conclusion: Promising results were obtained after the solitary application of Co-Q10 as well as when it was used as an adjunct to scaling and root planing for treatment of plaque induced gingivitis.

    The use of cyclosporine A (CsA) induces hyperplasia of the gingival epithelium in a site-specific response manner, but the molecular mechanism via which the lesion occurs is unclear. The present research aims to investigate the site-specific effect of CsA on the apoptosis of gingival epithelium associated with gingival hyperplasia. Forty Wistar rats were divided into CsA-treated and non-treated groups. Paraffin-embedded sections of mandibular first molars were selected for hematoxylin and eosin staining, immunohistochemistry analyses of bcl-2 and caspase-3, and the staining of terminal deoxynucleotidyl transfer-mediated dUTP nick-end labeling (TUNEL). The area of the whole gingival epithelium and the length of rete pegs were measured, and the number of bcl-2- and caspase-3-positive cells in the longest rete peg were counted. The analysis of variance for factorial designs and Fisher least significant difference test for post hoc analysis were used to determine the significance levels. In CsA-treated rats, bcl-2 expression was significantly upregulated, whereas caspase-3 expression was downregulated, along with a reduced number of TUNEL-positive cells. The site-specific distribution of bcl-2 was consistent with the site-specific hyperplasia of the gingival epithelium in CsA-treated rats. CsA inhibited gingival epithelial apoptosis via the mitochondrial pathway and common pathway. The antiapoptotic protein bcl-2 might play a critical role in the pathogenesis of the site-specific hyperplasia of gingival epithelium induced by CsA. There were mechanistic differences in the regulation of apoptosis for cells in the attached gingival epithelium, free gingival epithelium, and junctional epithelium.

    Aim The goal of this study is to characterize the changes in 33 biomarkers within the gingival crevicular fluid during the 3-week induction and 4-week resolution of stent-induced, biofilm overgrowth mediated, experimental gingivitis in humans. Methods Experimental gingivitis was induced in 25 subjects for 21 days followed by treatment with a sonic powered toothbrush for 28 days. Clinical indices and gingival crevicular fluids were collected weekly during induction and biweekly during resolution. Samples were analyzed using a bead-based multiplexing analysis for the simultaneous measurements of 33 biomarkers within each sample including cytokines, matrix-metalloproteinases and adipokines. Prostaglandin-E2 was measured by enzyme-linked immunoadsorbant assay. Statistical testing using general linear models with structured covariance matrices were performed to compare stent to contralateral (non-stent) changes in clinical signs and in biomarker levels over time. Results Gingivitis induction was associated with a significant 2.6-fold increase in interleukin 1-beta, a 3.1 fold increase in interleukin 1-alpha, and a significant decrease in multiple chemokines as well as matrixmetalloproteinases −1, −3 and 13. All changes in clinical signs and mediators rebounded to baseline in response to treatmentin the resolution phase. Conclusions Stent-induced gingivitis is associated with marked, but reversible increases in interleukins 1-alpha and 1-beta with suppression of multiple chemokines as well as selected matrixmetalloproteinases.

    Full Text Available Background: Periodontal diseases are chronic bacterial infections that lead to gingival inflammation, periodontal tissue destruction, and alveolar bone loss. Acting as powerful allies in the fight against periodontal disease, natural compounds can help safeguard against lethal age-related diseases that emanate from our mouths. Punica granatum (pomegranate shrub belongs to the Punicaceae family which has been used as an astringent, hemostatic, antidiabetic, antihelmintic, and also for diarrhea and dysentery. The aim of the present work was to investigate the possible efficacy of hydroalcoholic extract from Punica granatum fruit as an antiplaque and antigingivitis agent when compared with chlorhexidine. Materials and Methods: Twenty subjects diagnosed with chronic generalized gingivitis were selected and randomly divided into two groups: Group 1 - Pomegranate mouthwash and Group 2 - Chlorhexidine mouthwash. Punica granatum mouthwash was prepared using raw Punica granatum fruit. Patients were instructed to use the prescribed mouthwash for 15 days. Clinical evaluation was undertaken using the gingival index, the plaque index, and bleeding on probing at baseline, 7 days, and 15 days. Results: The clinical study observed significant improvement in gingival status in both the sites (P<0.05. Subjects using Punica granatum mouthwash showed significant improvement in bleeding and gingivitis score as compared with chlorhexidine. In contrast, Punica granatum was shown not to be so effective in reducing plaque scores. Chlorhexidine still remains as a standard in the reduction of plaque in subjects with gingivitis. Conclusion: Punica granatum mouthwash is beneficial in improving gingival status due to its profound styptic action, with sufficient reduction in plaque scores.

    Insufficient information on the cellular composition of long-standing gingivitis lesions without signs of attachment loss makes an understanding of differences in cellular composition between "destructive" and "nondestructive" periodontal lesions difficult. The aim of the current study was to analyze differences in cell characteristics between lesions representing long-standing gingivitis and severe periodontitis. Two groups of patients were recruited. One group consisted of 36 patients, 33-67 years of age, with severe generalized periodontitis (periodontitis group). The second group consisted of 28 patients, 41-70 years of age, with overt signs of gingival inflammation but no attachment loss (gingivitis group). From each patient a gingival biopsy was obtained from one selected diseased site and prepared for immunohistochemical analysis. Periodontitis lesions were twice as large and contained significantly larger proportions, numbers and densities of cells positive for CD138 (plasma cells) and CD68 (macrophages) than did gingivitis lesions. The proportion of B cells that expressed the additional CD5 marker (B-1a cells) was significantly larger in periodontitis lesions than in gingivitis lesions. The densities of T cells and B cells did not differ between periodontitis lesions and gingivitis lesions. T cells were not the dominating cell type in gingivitis lesions, as B cells together with their subset plasma cells comprised a larger number and proportion than T cells. Periodontitis lesions at teeth with advanced attachment and bone loss exhibit quantitative and qualitative differences in relation to gingivitis lesions at teeth with no attachment and bone loss. It is suggested that the large number and high density of plasma cells are the hallmarks of advanced periodontitis lesions and the most conspicuous difference in relation to long-standing gingivitis lesions. © 2014 John Wiley & Sons A/S.

    This study was performed to evaluate the microbiological profile and the calprotectin expression in gingival crevicular fluid (GCF) in spontaneous and experimentally induced gingival inflammation. Thirty-seven periodontally healthy subjects were evaluated in real life conditions (N-O gingivitis) as well as after 21 days of experimental gingivitis trial (E-I gingivitis). During the experimental gingivitis trial, in one maxillary quadrant (test quadrant), gingival inflammation was induced by oral hygiene abstention, while in the contralateral (control) quadrant, oral hygiene was routinely continued. The results of the study showed that (1) the microbiological profile of quadrants where gingival inflammation was experimentally induced (i.e., E-I test quadrants) differed significantly from that of either quadrants where gingival inflammation was controlled by proper plaque control (i.e., E-I control quadrants) or quadrants with N-O gingivitis, and (2) GCF calprotectin was significantly higher at E-I test quadrants compared to either E-I control quadrants or quadrants with N-O gingivitis. A positive intrasubject correlation was found between GCF concentration of calprotectin at sites presenting N-O and E-I gingivitis. N-O and E-I gingivitis showed a different microbiological profile of the subgingival environment. GCF calprotectin is a reliable marker of gingival inflammation, and its concentration in N-O gingivitis is correlated with its expression in E-I gingivitis. The modality of plaque accumulation seems to affect the subgingival microbiological profile associated with a gingivitis condition. Calprotectin levels in GCF may be regarded as a promising marker of the individual susceptibility to develop gingival inflammation in response to experimentally induced plaque accumulation.

    To evaluate the associations between gingivitis, emotional status and quality of life in children. Sixty-four Brazilian students (11 to 12 years old) were examined for clinical and self-reported gingivitis. The participants were divided into two groups: those with gingivitis (n = 21) and controls (n = 43). Quality of life, anxiety and depression were measured using self-administered questionnaires. Saliva was collected 30 min after waking and at bedtime to measure the diurnal decline in salivary cortisol. The results were analysed using bivariate and multivariate analyses. There were significantly more female participants in the control group. Approximately 90% of the children with gingivitis had good oral hygiene and 10.5% had satisfactory oral hygiene. There was a significant positive correlation between anxiety and depression in both clinical groups. Anxiety was negatively correlated with quality of life in the control group. Depression was negatively correlated with quality of life and cortisol concentrations in the group with gingivitis, and with quality of life in the control group. Children with gingivitis were more likely to be older and males. Older children are more likely to experience gingival bleeding. The presence of gingivitis in children may be associated with worse psychological well-being, possibly compromising the quality of life.

    Full Text Available Gingival enlargement is a common clinical feature of gingival and periodontal diseases. Currently, more than 20 prescription medications are associated with gingival enlargement. Although the mechanisms of action may be different, the clinical and microscopic appearance of drug-induced gingival enlargement is similar with any drug. Gingival enlargement produces esthetic changes, and clinical symptoms including pain, tenderness, bleeding, speech disturbances, abnormal tooth movement, dental occlusion problems, enhancement of caries development and periodontal disorders. Sodium valproate is considered to produce gingival enlargement, but very rarely. This case report features sodium valproate induced gingival enlargement in a patient with pre-existing chronic periodontitis, who came to the Dental Department, Chinmaya Mission Hospital, Bangalore. The case is special as the patient did not develop the enlargement in spite of taking phenytoin for 1 year and developed enlargement with sodium valproate within 6 months.

    The aim of this study was to compare the efficacy of a dentifrice without sodium lauryl sulfate (SLS) to a dentifrice with SLS in young adults aged 18-34 years on gingivitis. One hundred twenty participants (non-dental students) with a moderate gingival inflammation (bleeding on probing at 40-70 % of test sites) were included in this randomized controlled double blind clinical trial. According to randomization, participants had to brush their teeth either with dentifrice without SLS or with SLS for 8 weeks. The primary outcome was bleeding on marginal probing (BOMP). The secondary outcomes were plaque scores and gingival abrasion scores (GA) as well as a visual analogue scale (VAS) score at exit survey. Baseline and end differences were analysed by univariate analysis of covariance (ANCOVA) test, between group differences by independent t test and within groups by paired sample t test. BOMP improved within groups from on average 0.80 at baseline to 0.60 in the group without SLS and to 0.56 in the group with SLS. No statistical difference for BOMP, plaque and gingival abrasion was found between both groups. VAS scores for taste, freshness and foaming effect were significantly in favour of the SLS-containing dentifrice. The test dentifrice without SLS was as effective as a regular SLS dentifrice on gingival bleeding scores and plaque scores. There was no significant difference in the incidence of gingival abrasion. In patients diagnosed with gingivitis, a dentifrice without SLS seems to be equally effective compared to a dentifrice with SLS and did not demonstrate any significant difference in gingival abrasion. In patient with recurrent aphthous ulcers, the absence of SLS may even be beneficial. However, participants indicate that they appreciate the foaming effect of a dentifrice with SLS more.

    Full Text Available Background and Design: Although gingival hyperpigmentation is not a medical problem, people who have moderate or severe gingival pigmentation, particularly patients having a gummy smile, frequently request cosmetic treatment. For gingival depigmentation, different treatment modalities have been reported such as surgical treatment, cryotherapy, electrosurgery, and laser therapy. Materials and Methods: Twenty-one patients with gingival melanin pigmentation were included in the study. We applied liquid nitrogen to the hyperpigmented area for 5-10 seconds using open spray technique with a cryogun. Clinical observations for intensity of pigmentation were recorded at baseline and 3 months after the treatment. Clinical parameters, such as bleeding, swelling, redness, and healing, were evaluated immediately after the cryotherapy and 24 hours, and 1 week after the treatment. We used a numeric pain scale to evaluate the pain level. Results: Three months after the treatment, the mean gingival melanin pigmentation score decreased from 41.62±16.58 to 19.28±11.85. The difference between pretreatment and posttreatment mean scores was found to be statistically significant.Discussion: Removal of gingival melanin pigmentation can be performed safely by open spray cryotherapy in dermatology clinics.

    Horse riding and horse handling are dangerous. There is a lack of knowledge concerning the incidence of hospitalization due to horse-related injuries and types of injuries in Israel. During the last two decades we have observed an increasing incidence of hospitalizations due to horse-related injuries at our medical center as well as the frequent involvement of pediatric patients. To investigate these injuries with respect to type, incidence and modes of prevention. We conducted a retrospective study of medical records for all patients admitted to Assaf Harofeh Medical Center due to horse-related injury between January 1984 and December 2008. A telephone questionnaire was used to complete the data. Eighty-nine subjects (267 injuries) were included in the study. Most of them were not professional horse riders or horse handlers. Helmet use was reported in only 28% of the participants. The number of subjects with horse-related injuries and the percentage of pediatric involvement increased during the study period. Falling from a horse was the most frequent cause of injury (60.67%), followed by being kicked (13.4%). Head and extremities were the most affected areas. On admission, 33.7% had a potential severe injury score. Forty-two participants (47%) had underlying fractures, mostly in the upper extremities. In the pediatric population, 16.2% (vs. 0% adults) rode horses for therapeutic reasons. Seventeen subjects reported having long-term consequences. The findings are similar to those described in other parts of the world. Horseback riding-related injuries are increasing, which emphasizes the need for safety education programs in Israel.

    Full Text Available Objective: To determine the prevalence of gingivitis and perception of gingival colour among pregnant women attending the antenatal clinic of a tertiary health institution in Lagos State, Nigeria. Materials and Methods: A single-point assessment was conducted using a self-reported questionnaire completed by participants. Information such as patients′ age, gestational age, educational status, occupation, and perception of gingival colours was obtained. Furthermore, the participants were examined by trained dentists to determine their gingival colours and the presence and severity of gingival inflammation. The data obtained were processed, and descriptive and comparative analyses were done using Epi info version 3.5.1 (2008. Statistical significance was established at P values <0.05. Results: Four hundred and forty-five pregnant women aged between 18 years and 43 years [mean age: 30.3 (±4.61 years] participated in the study. Gestational age was between 4 weeks and 41 weeks with a mean of 23.49 (±9.53 weeks. The prevalence of gingivitis was 85.2%. Two hundred and thirty (51.7% participants described their gingival colour as pink, 127 (28.5% as red, 51 (11.5% as black, 3 (0.7% as white, 2 (0.4% as brown, and 32 (7.2% could not determine the colour of their gingivae. Two hundred and ten (47.2% participants knew that pink was the normal colour of a healthy gingiva. From objective clinical examinations by dentists, 344 (77.3% patients had pink gingivae, 85 (19.1% had pigmented gingivae, and only 16 (3.6% had red gingivae. Conclusion: The higher prevalence of gingivitis during pregnancy is well-established and that observation is corroborated by this study. Since a change in gingival colour may be an early indication of gingival inflammation, early detection and prompt treatment could prevent further periodontal deterioration. Hence, there is the need to incorporate and intensify oral health education during antenatal care so that pregnant women are

    The grey-bluish discoloration of gingiva (known as "amalgam tattoo") does not appear only in the presence of amalgam restorations. It may also be seen in cases of teeth restored with cast dowels and porcelain-fused-to-metal (PFM) restorations. The aim of this article was to determine the clinical characteristics of abutment teeth with gingival discoloration. This research was conducted on 25 patients referred for cast dowel and PFM restorations. These restorations were manufactured from Ni-Cr alloys. Ninety days after cementing the fixed prosthodontic restorations, the abutment teeth (n = 61) were divided into a group with gingival discoloration (GD) (n = 25) and without gingival discoloration (NGD) (n = 36). The control group (CG) comprised the contralateral teeth (n = 61). Plaque index, gingival index, clinical attachment level, and probing depth were assessed before fabrication and also 90 days after cementation of the PFM restorations. The gingival index, clinical attachment level, and probing depths of the abutment teeth that had GD were statistically higher before restoration, in comparison with the abutment teeth in the NGD and control groups. Ninety days after cementation, the abutment teeth with GD had significantly lower gingival indexes and probing depths, compared to the abutment teeth in the NGD group. Both abutment teeth groups (GD and NGD) had significantly higher values of clinical attachment levels when compared to the control group. There were no statistically significant differences in plaque index values between the study groups. The results of this study indicated that impairment of periodontal status of abutment teeth seemed to be related to the presence of gingival discolorations. Therefore, fabrication of fixed prosthodontic restorations requires careful planning and abutment teeth preparation to minimize the occurrence of gingival discolorations. With careful preparation of abutment teeth for cast dowels and crown restorations it may be

    The purpose of this study was to determine the level of gingival inflammation and the prevalence of periodontopathogenic microorganisms in adolescents with chronic gingivitis, as well as to compare the effectiveness of two approaches in gingivitis treatment-basic therapy alone and basic therapy + adjunctive low-level laser therapy (LLLT). After periodontal evaluation, the content of gingival pockets of 140 adolescents with gingivitis was analyzed by multiplex PCR for the presence of P. gingivalis, A. actinomycetemcomitans, T. forsythensis and P. intermedia. Subsequent to bacteria detection, the examinees were divided into two groups with homogenous clinical and microbiological characteristics. Group A was subjected to basic gingivitis therapy, and group B underwent basic therapy along with adjunctive LLLT. A statistically significant difference between the values of plaque-index (PI) and sulcus bleeding index (SBI) before and after therapy was confirmed in both groups (pgingivitis should be regarded as a sign for dentists to foster more effective oral health programs. LLLT appears to be beneficial as adjuvant to basic therapy.

    Gingivitis affects an estimated 80% of the population, and is characterized as the world's most predominant inflammatory periodontal disease. Without intervention, gingivitis can advance to alveolar bone loss. Therefore, the primary goal in patients suffering with gingivitis is to control plaque buildup and soft tissue inflammation. Current guidelines consider chlorhexidine as the gold standard in the prevention and treatment of gingivitis. However, negative side effects of chlorhexidine, including oral mucosal erosion, discoloration of teeth, and bitter taste, provide an opportunity for alternative medications. Turmeric, a commonly used herb, possesses anti-inflammatory, antioxidant, antibacterial, antiviral, and antifungal properties. By virtue of these properties, multiple controlled trials have been performed to investigate the efficacy of turmeric in gingivitis. The aim of this comprehensive review is to summarize and evaluate the evidence on the efficacy of turmeric as compared to chlorhexidine in the prevention and treatment of gingivitis. PubMed, MedLine (Web of Science), and EBSCO (academic search complete) were utilized as primary literature search tools. The following search strategy was used: ((turmeric OR curcumin OR curcuma) AND (gingivitis OR "gum inflammation")). Five reviewed studies show that both turmeric and chlorhexidine significantly decrease plaque index (PI) and gingival index (GI), and can therefore be used in the prevention and treatment of gingivitis. Both chlorhexidine and turmeric can be used as an adjunct to mechanical means in preventing and treating gingivitis. However, trials longer than 21 days with a greater number of patients are necessary to further evaluate the comparison between turmeric and chlorhexidine. Copyright © 2016 Elsevier Ltd.

    To describe the epidemiology of surgical and anesthetic procedures in patients recently diagnosed as having a concussion due to mild traumatic brain injury. Study patients presented to a tertiary care center after a concussion due to mild traumatic brain injury from July 1, 2005, through June 30, 2015, and underwent a surgical procedure and anesthesia support under the direct or indirect care of a physician anesthesiologist. During the study period, 1038 patients met all the study inclusion criteria and subsequently received 1820 anesthetics. In this population of anesthetized patients, rates of diagnosed concussions due to sports injuries, falls, and assaults, but not motor vehicle accidents, increased during 2010-2011. Concussions were diagnosed in 965 patients (93%) within 1 week after injury. In the 552 patients who had surgery within 1 week after concussive injury, 29 (5%) had anesthesia and surgical procedures unrelated to their concussion-producing traumatic injury. The highest use of surgery occurred early after injury and most frequently required general anesthesia. Orthopedic and general surgical procedures accounted for 57% of procedures. Nine patients received 29 anesthetics before a concussion diagnosis, and all of these patients had been involved in motor vehicle accidents and received at least 1 anesthetic within 1 week of injury. Surgical and anesthesia use are common in patients after concussion. Clinicians should have increased awareness for concussion in patients who sustain a trauma and may need to take measures to avoid potentially injury-augmenting cerebral physiology in these patients.

    Current methods available for periodontal disease diagnosis are seriously deficient in terms of accuracy, in the ability to predict ongoing or future disease activity and indeed in determining whether previously diseased sites are in an arrested phase or still active. One area that is receiving a great deal of attention is the biochemical investigation of gingival crevicular fluid (GCF). β-glucuronidase (βG) is one of the enzymes found in GCF that is involved in degradation of the ground substance and fibrillar components of host connective tissue. GCF βG activity might be a good indicator or predictor of periodontal disease activity. This study was conducted to estimate and compare the GCF βG levels in patients with healthy periodontium, chronic gingivitis, and chronic periodontitis. Subjects were classified into three groups of 20 patients each; healthy individuals, chronic gingivitis, and chronic periodontitis. After recording the plaque index, gingival index and probing pocket depth, 1 μL GCF was collected by placing a calibrated microcapillary pipette extracrevicularly and transferred to sterile plastic vials containing 350 μL of normal saline with 1% bovine serum albumin. Analysis of βG was done by spectrophotometry. βG levels in GCF were significantly higher in chronic periodontitis group (mean value - 2.04743), followed by chronic gingivitis group (mean - 1.11510) and healthy group (0.53643). Increased βG levels were observed in patients with increased periodontal destruction, hence GCF βG levels can be used as biochemical marker for periodontal disease activity.

    Full Text Available Gingival melanoacanthoma is a rare, benign pigmented lesion characterized clinically by sudden onset and rapid growth of a macular brown black lesion and histologically by acanthosis of superficial epithelium and proliferation of dendritic melanocytes. This article reports a previously undescribed case of pigmented unilateral diffuse gingival enlargement, which on histopathological examination proved to be melanoacanthoma. Intraoral examination revealed pigmented unilateral diffuse gingival enlargement in relation to second and third quadrants buccally, palatally/lingually. Based on these clinical findings, gingivectomy was performed and the excised tissue was sent for biopsy. Microscopic examination revealed acanthotic and parakeratotic surface epithelium with dendritic melanocytes distributed in basal and suprabasal layers of the epithelium. 1 year follow-up recall revealed no recurrence of lesion at the surgical sites. Our patient exhibits an unusual clinical presentation of melanoacanthoma of gingiva. Pigmented gingival overgrowth of recent origin and without any etiologic factors warrants histopathologic examination.

    To explore a gingival shade matching method and to evaluate the precision and accuracy of a dental spectrophotometer modified to be used in gingival color measurement. Crystaleye, a dental spectrophotometer (Olympus, Tokyo, Japan) with a custom shading cover was tested. For precision assessment, two experienced experimenters measured anterior maxillary incisors five times for each tooth. A total of 20 healthy gingival sites (attached gingiva, free gingiva and medial gingival papilla in anterior maxillary region) were measured,the Commission Internationale de I' Eclairage (CIE) color parameters (CIE L*a*b*) of which were analyzed using the supporting software. For accuracy assessment, a rectangular area of approximately 3 mm×3 mm was chosen in the attached gingival portion for spectral analysis. PR715 (SpectraScan;Photo Research Inc.,California, USA), a spectroradiometer, was utilized as standard control. Average color differences (ΔE) between the values from PR715 and Crystaleye were calculated. In precision assessment,ΔL* between the values in all the test sites and average values were from(0.28±0.16)to(0.78±0.57), with Δa*and Δb* from(0.28±0.15)to (0.87±0.65),from(0.19±0.09)to( 0.58±0.78), respectively. Average ΔE between values in all test sites and average values were from (0.62 ± 0.17) to (1.25 ± 0.98) CIELAB units, with a total average ΔE(0.90 ± 0.18). In accuracy assessment, ΔL* with control device were from(0.58±0.50)to(2.22±1.89),with Δa*and Δb* from(1.03±0.67)to(2.99±1.32),from(0.68±0.78)to(1.26±0.83), respectively. Average ΔE with the control device were from (2.44±0.82) to (3.51±1.03) CIELAB units, with a total average ΔE (2.96 ± 1.08). With appropriate modification, Crystaleye, the spectrophotometer, has demonstrated relative minor color variations that can be useful in gingival color measurement.

    The aim of the current research was to assess the prevalence of gingival recession and to investigate possible associations among this condition, periodontal and epidemiological variables in a sample of young Greek adults in a general dental practice. A total of 1,430 young adults was examined clinically and interviewed regarding several periodontal and epidemiological variables. Collected data included demographic variables, oral hygiene habits and smoking status. Clinical examination included the recording of dental plaque, supragingival calculus presence, gingival status and buccal gingival recession. Multivariate logistic regression analysis model was performed to access the possible association between gingival recession and several periodontal and epidemiological variables as potential risk factors. The overall prevalence of gingival recession was 63.9%. The statistical analysis indicated that higher educational level [OR= 2.12, 95% CI= 0.53-8.51], cigarette smoking [OR= 1.97, 95% CI= 1.48-7.91], frequent tooth brushing [OR= 0.98, 95% CI= 0.56-1.96], presence of oral piercing [OR= 0.92, 95% CI= 0.38-1.58], presence of gingival inflammation [OR= 4.54, 95% CI= 1.68-7.16], presence of dental plaque [OR= 1.67, 95% CI= 0.68-2.83] and presence of supragingival calculus [OR=1.34, 95% CI= 0.59-1.88], were the most important associated factors of gingival recession. The observations of the current research supported the results from previous authors that several periodontal factors, educational level and smoking were significantly associated with the presence of gingival recession, while presence of oral piercing was a new factor that was found to be associated with gingival recession. Key words:Gingival recession, prevalence, risk factors, young adults.

    The aim of this systematic review was to evaluate the effectiveness of Azadirachta indica (neem)-based herbal mouthrinse in improving plaque control and gingival health. Literature search was accomplished using electronic databases (PubMed, Cochrane Central Register of Controlled Trials and EMBASE) and manual searching, up to February 2015, for randomized controlled trials (RCTs) presenting clinical data for efficacy of neem mouthrinses when used alone or as an adjunct to mechanical oral hygiene as compared to chlorhexidine mouthrinses for controlling plaque and gingival inflammation in patients with gingivitis. Of the total 206 articles searched, three randomized controlled trials evaluating neem-based herbal mouthrinses were included. Due to marked heterogeneity observed in study characteristics, meta-analysis was not performed. These studies reported that neem mouthrinse was as effective as chlorhexidine mouthrinse when used as an adjunct to toothbrushing in reducing plaque and gingival inflammation in gingivitis patients. However, the quality of reporting and evidence along with methods of studies was generally flawed with unclear risk of bias. Despite the promising results shown in existing randomized controlled trials, the evidence concerning the clinical use of neem mouthrinses is lacking and needs further reinforcement with high-quality randomized controlled trials based on the reporting guidelines of herbal CONSORT statement. © 2016 John Wiley & Sons A/S.

    To assess associations of socio-demographic, behavioural and the extent of gingivitis and calculus with oral health-related quality of life (OHRQoL) in nationally representative samples of 12- and 15-year-old Thai children. In the Thailand National Oral Health Survey, 1,063 twelve-year olds and 811 fifteen-year olds were clinically examined and interviewed for OHRQoL using the Child-OIDP and OIDP indices, respectively, and completed a behavioural questionnaire. We assessed associations of condition-specific impacts (CS-impacts) with gingivitis and calculus, adjusted for socio-demographic and behavioural factors. Gingivitis and calculus were highly prevalent: 79.3% in 12-year and 81.5% in 15-year olds. CS-impacts relating to calculus and/or gingivitis were reported by 26.0% of 12-year and 29.6% of 15-year olds. Except for calculus without gingivitis, calculus and/or gingivitis in any form was significantly related to any level of CS-impacts. At a moderate or higher level of CS-impacts, there were significant relationships with extensive calculus and/or gingivitis in 12-year olds and for extensive gingivitis and gingivitis without calculus in 15-year olds. Gingivitis was generally associated with any level of CS-impacts attributed to calculus and/or gingivitis. CS-impacts were related more to gingivitis than to calculus. © 2012 John Wiley & Sons A/S.

    During the past few decades, terrorist acts have been an unfortunate reality worldwide. There is a striking paucity of research investigating the multitude of long-term outcomes after severe physical injury due to terrorist attacks, a unique subgroup of trauma patients. The purpose of this study was to provide a profile of the long-term health-related quality of life (HR-QOL) after injury due to terrorist attacks and to explore the relationships between Post Traumatic Stress Disorder (PTSD), occupational status and injury severity with HR-QOL. We included 35 survivors of terrorist attacks living in the community, two years on average after the injury, mean age at follow-up = 32.1 (±13.8), mean Injury Severity Score (ISS) = 27 (±14.2). The subjects were recruited from consecutive admissions to a rehabilitation department in a tertiary care center between September 2000 - June 2004. Most of the subjects suffered multiple trauma. The main outcome measures were the Short-Form Health Survey (SF-36), Post Traumatic Diagnostic Scale and return to work rates. The mean scores on 6/8 of the SF-36 subscales were significantly lower among the survivors compared to normative population norms. Post Traumatic Stress Disorder (PTSD) was found in 39% of the sample and 43% did not resume their main occupation two years after the injury. Multivariate analysis of variance of PTSD and occupational status (returned vs. did not return to work) on quality of life scores revealed significant main effects for both PTSD (p=. 000) and occupational status (p=. 005) with no interaction effect (p=. 476). No significant correlations were found between injury severity and the SF-36 scores. This study demonstrated the long-term impact of injury due to terrorism. Results showed independent effects of PTSD and occupational status on health related quality of life, two years after injury. These findings suggest that this group may benefit from intervention focusing on their emotional and

    Gingivitis is the most prevalent oral disease in children, being strongly associated to social gradients. Many studies have reported different results concerning the extent and intra-oral distribution of gingivitis in children. The aim of this study was to investigate the epidemiologic parameters and socio-related risk factors of gingivitis in the 10-17-year-old Bucharest schoolchildren population and to analyze its intra-oral distribution. Cross-sectional data were obtained from 1595 schoolchildren, social condition being assigned using a simple questionnaire. Classes of students were used as clusters in a single-stage cluster sampling method. An intra-oral exam was performed for all the children included in this study. Silness and Löe scores, prevalence and the extent of gingivitis were calculated. The gingival scores showed a mild inflammation and the prevalence of gingivitis was 91%. Boys had a higher gingival (0.19 vs. 0.18; p gingival conditions (p Gingivitis was more severe on the upper teeth, with the maximum score being reached at the right upper lateral incisor (0.63 on distal surface). Gingival condition in Bucharest schoolchildren population was associated to social gradients. School dental services are also another factor that seems to be related with gingivitis. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The aim of this study was to investigate the association of EBV and HPV with gingivitis and/or periodontitis according to the immunologic status. To this end, 74 oral biopsies from transplanted and non-transplanted individuals with the abovementioned oral manifestations were submitted to a screening by PCR for both viruses. According to the results, EBV was strongly associated with gingivitis and/or periodontitis in transplanted individuals (p = 0.011) but not HPV (p = 0.766). EBV-HPV co-detections did not enhance the presence of tissue injury as well. Although a causal relationship was not investigated in this study, the higher frequency of these two oncoviruses in lesion tissues must be investigated in follow-up studies, especially among immunocompromised individuals.

    To identify the patterns of ocular injury and to determine ocular morbidity resulting from the use of firecrackers. A prospective observational study of all patients presenting with ocular trauma consequent to fireworks usage in a tertiary eye care center in South India over a one-month period around the autumn festival of Diwali. We also reviewed the published literature from around the world reporting ocular injuries due to firecrackers. 49 patients were included in the study, out of which the vast majority (40/81%) were males. The mean age was 17 years. Almost an equal number of bystanders (24/48.9%) was affected as compared to people handling the fireworks (25/51%). 13 (26.53%) patients had open-globe injury whereas 33 (67.34%) patients had closed-globe injury. Twenty-two (44.8%) patients underwent surgical intervention. Eighteen (36.7%) patients had final vision less then 20/40 (range = 20/50 to No Perception of Light) with eight patients having no perception of light in the affected eye. Unregulated use of firecrackers can lead to significant ocular morbidity, mainly involving children, young males, and even innocent bystanders. A combination of public awareness and appropriate legislative laws should be formulated regarding the use of fireworks to decrease the load of needless blindness on society.

     Both dogs and bicycles are common in our society and thus a dog-bicycle interaction resulting in an injury to a cyclist is possible. It was the purpose of this study to investigate such injuries.  The National Electronic Injury Surveillance System (NEISS) data for the 10-year period from 2006 through 2015 associated with bicycles were accessed. Injuries involving dogs were identified and the mechanism of injury determined. Due to the stratified and weighted nature of the NEISS data, statistical analyses were performed with SUDAAN 10 software (RTI International, Research Triangle Park, North Carolina, United States). A p  dogs were involved in 35,254 (0.67%) cases. The average age for those involved with a dog was 33.2 years and it was 25.5 years for those in which dogs were not involved. There were more females in the dog group (34.1 vs. 27.6%). Dog involvement increased from ages 0 to 14 years, then decreased until the age of 20 years and then progressively increased. Dog-associated injuries most frequently occurred away from home, involved the knee and distal lower extremity, 49.1% sustaining dog bites. Dog bites were more common in younger individuals. Four injury mechanisms (chased by a dog, hit/collided with a dog, swerved/tried to avoid a dog or riding with a dog) accounted for 97.5% of the injuries. Those chased by a dog were younger, more commonly released from the emergency department, had an injury involving the lower extremity and frequently sustained a bite. The most severe injuries were in those who swerved/tried to avoid a dog or hit a dog.  Approximately 1% of injuries to bicyclists are associated with dogs; one-half sustained a bite. Potential/proposed prevention strategies could be educational materials regarding bicycles and dogs to owners, dog restraint, student/parent education and educational materials in waiting rooms of veterinarians, paediatricians, family practice physicians and emergency rooms.

    Introduction: Evaluating the health status of the gingival tissue represents an important objective in the daily practice. Inflammation changes the microcirculatory and micromorphological dynamics of human gingiva. Aim: The purpose of this study was to evaluate the microcirculation in subjects with moderate gingivitis and healthy gingiva by using laser Doppler flowmetry (LDF). Material and Methods: Recordings of the gingival microcirculation (GM) were taken from 20 healthy gingival sites and from 20 sites with moderate gingivitis. The gingival blood flows in the gingivitis group before treatment was significantly different from those in the healthy gingiva group. Signals were recorded with the aid of a laser Doppler MoorLab instrument VMS-LDF2 probe VP3 10 mm S/N 2482. Three consecutive determinations of the GM were registered for each site, as follows: before the initial therapy, at 24 hours after the initial therapy and then, 7 days after the initial therapy. The data were processed using the statistical analysis software SPSS v16.0.1. Results: The results of this preliminary study showed statistically significant differences among the GM values recorded before and after the initial therapy. Conclusions: LDF could be a useful, noninvasive, sensitive, reproducible, and harmless method for measuring gingival blood flow (gingival microcirculation) in humans.

    Presence of epithelial desquamation, erythema, and erosions on gingival tissue is usually described in the literature as desquamative gingivitis (DG). A wide range of autoimmune/dermatologic disorders can manifest as DG, although the two more common are oral lichen planus and mucous membrane pemphigoid. The aim of this study is to investigate prevalence of 11 periodontopathogenic microorganisms in patients with DG and to compare it with the microbiologic status of individuals affected by plaque-induced gingivitis (pGI). Cross-sectional clinical and microbiologic data were obtained from 66 patients (33 in each group). Subgingival plaque samples were analyzed using semiquantitative polymerase chain reaction analysis. Statistically significant difference, but with little clinical significance, was observed in gingival conditions between the two groups, probably due to the worse home control hygiene of patients with DG. Prevalence and levels of Aggregatibacter actinomycetemcomitans, Eikenella corrodens, and Fusobacterium nucleatum/periodonticum were statistically higher in samples from patients with DG than in those with pGI. In multivariate regression models, subgingival colonization of A. actinomycetemcomitans and F. nucleatum/periodonticum was not statistically associated with DG, whereas, high levels of E. corrodens were associated with 13-fold increased odds for DG. Microbiologic differences were found in subgingival plaque for patients with DG and pGI. This may suggest possible association between periodontal pathogens and DG.

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

    Full Text Available Smoking patients show reduction of inflammatory clinical signs that might be associated with local vasoconstriction and an increased gingival epithelial thickness. The purpose of this work was to evaluate the thickness of the marginal gingival oral epithelium in smokers and non-smokers, with clinically healthy gingivae or with gingivitis. Twenty biopsies were obtained from four different groups. Group I: non-smokers with clinically healthy gingivae (n = 5. Group II: non-smokers with gingivitis (n = 5. Group III: smokers with clinically healthy gingivae (n = 5. Group IV: smokers with gingivitis (n = 5. These biopsies were histologically processed, serially sectioned at 5 mm, stained with H. E., and examined by image analysis software (KS400, which was used to perform the morphometric evaluation and the quantification of the major epithelial thickness, the epithelial base thickness and the external and internal epithelial perimeters. Differences between the four groups were analyzed using ANOVA test and Tukey's test. The criteria for statistical significance were accepted at the probability level p < 0.05. A greater epithelial thickness was observed in smokers independent of the gingival health situation.

    Plaque-induced gingivitis can be alleviated by various treatment regimens. To probe the impacts of various anti-gingivitis treatments on plaque microflora, here a double blinded, randomized controlled trial of 91 adults with moderate gingivitis was designed with two anti-gingivitis regimens: the brush-alone treatment and the brush-plus-rinse treatment. In the later group, more reduction in both Plaque Index (TMQHI) and Gingival Index (mean MGI) at Day 3, Day 11 and Day 27 was evident, and more dramatic changes were found between baseline and other time points for both supragingival plaque microbiota structure and salivary metabonomic profiles. A comparison of plaque microbiota changes was also performed between these two treatments and a third dataset where 50 subjects received regimen of dental scaling. Only Actinobaculum, TM7 and Leptotrichia were consistently reduced by all the three treatments, whereas the different microbial signatures of the three treatments during gingivitis relieve indicate distinct mechanisms of action. Our study suggests that microbiota based signatures can serve as a valuable approach for understanding and potentially comparing the modes of action for clinical treatments and oral-care products in the future.

    The efficacy of blue light-emitting toothbrushes (B-LETBs) (405 to 420 nm, power density 2 mW/cm2) for reduction of dental plaques and gingival inflammation has been evaluated. Microbiological study has shown the multifactor therapeutic action of the B-LETBs on oral pathological microflora: in addition to partial mechanical removal of bacteria, photodynamic action suppresses them up to 97.5%. In the pilot clinical studies, subjects with mild to moderate gingivitis have been randomly divided into two groups: a treatment group that used the B-LETBs and a control group that used standard toothbrushes. Indices of plaque, gingival bleeding, and inflammation have been evaluated. A significant improvement of all dental indices in comparison with the baseline (by 59%, 66%, and 82% for plaque, gingival bleeding, and inflammation, respectively) has been found. The treatment group has demonstrated up to 50% improvement relative to the control group. We have proposed the B-LETBs to serve for prevention of gingivitis or as an alternative to conventional antibiotic treatment of this disease due to their effectiveness and the absence of drug side effects and bacterial resistance.

    Gingival enlargement frequently occurs in transplant patients receiving immunosuppressive drugs. It was hypothesized that gingival enlargement associated with cyclosporine use results from reduced degradation of extracellular matrix in the gingiva. Matrix metalloproteinase-3 (MMP-3) is involved in biodegradation of the extracellular matrix, and its inhibition may contribute to an abnormal accumulation of fibronectin and proteoglycans, which are MMP-3 substrates. The aim of this study was to investigate whether an association exists between MMP-3 genotypes and gingival enlargement in kidney transplant patients medicated with cyclosporine A. Sixty-four unrelated kidney transplant patients suffering from gingival overgrowth, as well as 111 control transplant patients without gingival overgrowth, were enrolled in the study. Gingival overgrowth was assessed 6 mo after transplantation. During the post-transplant period all patients were given cyclosporine A as a principal immunosuppressive agent. MMP-3 polymorphism was determined using a PCR restriction fragment length polymorphism assay. In kidney transplant patients suffering from gingival overgrowth the mean gingival overgrowth score was 1.35 +/- 0.57, whereas in control subjects the mean gingival overgrowth score was 0.0. The distribution of MMP-3-1178A/dupA alleles among all kidney transplant patients, as well as in the two study subgroups, did not differ significantly from Hardy-Weinberg equilibrium. The frequency of the MMP-3-1171A/A genotype (28.1% for gingival overgrowth vs. 26.1% for controls) and of the MMP-3-1171dupA/dupA genotype (32.8% for gingival overgrowth vs. 22.5% for controls) was similar for both study groups. The risk of gingival overgrowth was lowest among patients carrying the MMP-3-1171A/dupA genotype (odds ratio 0.52), but this did not differ markedly from the other genotypes. No association between MMP-3 gene polymorphism and gingival overgrowth was revealed in kidney transplant patients

    The use of lasers in periodontology is a matter of debate, mainly because of the lack of consensual therapeutic protocols. In this randomized, split-mouth trial, the clinical efficacy of two different photoablative dental lasers, erbium:yttrium-aluminum-garnet (Er:YAG) and diode, for the treatment of gingival hyperpigmentation is compared. Twenty-one patients requiring treatment for mild-to-severe gingival hyperpigmentation were enrolled. Maxillary or mandibular left or right quadrants were randomly subjected to photoablative deepithelialization with either Er:YAG or diode laser. Masked clinical assessments of each laser quadrant were made at admission and days 7, 30, and 180 postoperatively by an independent observer. Histologic examination was performed before and soon after treatment and 6 months after irradiation. Patients also compiled a subjective evaluation questionnaire. Both diode and Er:YAG lasers gave excellent results in gingival hyperpigmentation. However, Er:YAG laser induced deeper gingival tissue injury than diode laser, as judged by bleeding at surgery, delayed healing, and histopathologic analysis. The use of diode laser showed additional advantages compared to Er:YAG in terms of less postoperative discomfort and pain. This study highlights the efficacy of diode laser for photoablative deepithelialization of hyperpigmented gingiva. It is suggested that this laser can represent an effective and safe therapeutic option for gingival photoablation.

    Full Text Available Gingival enlargement in the interdental papillae, thickened, rounded gingival contour and discomfort became major issues that must be treated in order to be optimal appearance and function. Gingival enlargement that experienced fibrosis would not disappear with only plaque control, but required surgery that is gingivectomy and gingivoplasty. The 24-year-old woman came to the periodonsia clinic with complaints maxillary anterior gingiva swelled at teeth 11-21 with plaque index 52%. The depth of the tooth pocket 11: labial (mesial: 4, medial: 1, distal: 3. Palatal (mesial: 3, medial: 2, distal 1. The depth of the tooth pocket 21 is labial (mesial: 4, medial: 1, distal: 1, palatal (mesial: 3, medial: 1, distal 1. Gingivectomy treatment and gingivoplasty were performed with the aim of eliminating pockets and restore physiologic gingival contour which can help prevent the recurrence of the disease periodontal. In performing surgical gingivectomy and gingivoplasty, which must be considered is to minimize the disposal of gingival tissue to maintain the aesthetic, adequate access to the bone defect in order to make good corrections, and the minimization of bleeding and discomfort after surgery.

    Aim To assess endotoxemia episodes and subsequent changes in serum inflammatory biomarkers using the experimental gingivitis model Materials and Methods Data from 50 healthy black and white adult males and females were compared for serum concentrations of endotoxin, and serum biomarkers [neutrophil oxidative activity, interleukin (IL)-1β, IL-6, IL-8, C-reactive protein, and fibrinogen] at baseline, at 3 weeks of experimental gingivitis, and after 2 weeks of recovery. Means were compared using repeated measures ANOVA. Results Endotoxemia was reported in 56% of the serum samples at three weeks of induced gingivitis. At two weeks of recovery, endotoxin levels decreased to levels similar to those reported at baseline. Neutrophil oxidative activity increased significantly following three weeks of gingivitis versus baseline (pgingivitis was associated with endotoxemia and hyperactivity of circulating neutrophils, but not with changes in systemic levels of cytokines and acute phase proteins. This may be attributed to the mild nature and the short duration of the induced gingivitis. PMID:21320151

    Full Text Available Periodontal attachment loss in the maxillary anterior region can often lead to esthetic and functional clinical problems including disproportional and elongated clinical crowns and visible interdental embrasures. Gingival replacement prosthesis has historically been used to replace lost tissue. A gingival mask is an easily constructed and practical device to optimize the esthetic and functional outcome in these special situations while permitting cleansibility of the prosthesis and supporting tissues. This is a case report of a young female patient treated using silicon gingival veneer with a 2-year follow-up. The silicon gingival mask has enabled the patient to regain her lost smile and face people with newly found confidence also enhancing the esthetic appearance. Virtually, no problem was encountered during the 2 years of usage of the veneer and the patient continues to use it comfortably.

    Full Text Available Purpose: We report a rare case of ocular injury due to potassium permanganate (KMnO4 granules in a child. Methods: This is a retrospective case report. Results: A 2-year-old boy was transferred to our emergency room with severe pain in his right eye, inflamed eyelids, and brownish stains on his fingers. Chemical injury was suspected. Copious eye irrigation was immediately performed. Diffuse brownish splotches were then observed at the inferior bulbar conjunctiva. Otherwise, systemic organs were intact. Complete eye exam under general anesthesia revealed a 5-mm epithelial defect at the central cornea, along with generalized conjunctival injection and limbal ischemia, inferiorly. Multiple semi-dissolved granules of KMnO4 trapped in the inferior fornix were identified. The chemical particles were gradually washed out and removed; however, the brownish stains remained. The patient received preservative-free steroid, antibiotic eye drops, and lubricants as regular management for mild to moderate degree of ocular burn. Pseudomembrane developed early and transformed into symblepharon within a few days after the injury. Membrane adhesion was lysed, and more aggressive medications were then substituted. Commercial amniotic membrane (PROKERA® was also applied to promote wound healing and to prevent recurrence of symblepharon. The ocular surface was eventually restored, and corneal transparency was preserved. Conclusion: Ocular injury with the granular form of KMnO4 is rare. Its toxicity is comparable to concentrated KMnO4 solution. However, the dissolved particles that had been absorbed in the stained conjunctiva were continuously released and damaged the ocular surface more than we primarily anticipated. Awareness of this condition and prompt management yield a good treatment outcome.

    This study shows that the theft of copper, mainly from electrical wires, is becoming a more frequent crime as the value of this metal rises. We have collected all the data from the Burn Centre of the Hospital of Palermo, Italy, from 1992 to 2007. Over the last two decades, we assisted to a dramatic increase of patients admitted to our hospital, reporting burn injuries while attempting to steal it in dangerous conditions. The circumstances of the injury, the clinical management of the case, and the long-term consequences are presented and discussed. We found that the electrical burn related to the theft of copper is often a life-threatening event because of the high-voltage electrical current passing through the patients. Patients, due to the type of activity, often requiring physical effort, were generally young and healthy. From a review of the literature on the subject, we have noticed that theft of copper is not reported as an important risk factor for electrical burns. Our report clearly shows that theft of copper-related electrical injury is becoming more frequent in the community and should be added as a "new" risk factor. The already high incidence reported here may actually be lower than the actual incidence because many patients tend not to come to the hospital because of the risk of being prosecuted by the police.

    Objective: The aim of the this study was to evaluate the perception of smile esthetics and alterations in cases of gingival plastic surgery for correction of a gummy smile, by means of alterations in smile photograph among dentistry degree students. Materials and Methods: A frontal smile photograph of a 40-year-old woman having normal occlusion was used with diverse compositions of gingival exposure level and crown length of maxillary teeth. The eight photographs were evaluated by 216 dentistry students in five class groups (1st, 2nd, 3rd, 4th and 5th classes). Results: The results revealed that almost all of the class’ students perceived differences between images, additionally, the highest percentage of students that answered “no difference” was 12% at 1st class’ students. 1st and 2nd class’ students most liked photograph which is 2.5 mm gingival display and 3rd class students liked two different photographs which are 2.5 mm gingival display and 2 mm gingival display whereas 4th class students preferred two different photographs which are 1.5 mm gingival display and 1 mm gingival display, 5th class students preferred photograph which is 1.5 mm gingival display as the most. Conclusion: Esthetic perception of smile improve as a student passes to higher study classes in terms of gingival exposure. The harmonious display of gingiva exhibits an important effect in the smile esthetics rather than reduced or excessive display. PMID:27403061

    It has been shown that inadequate sleep has deleterious effects on health by suppressing immunity and promoting inflammation. The aim of this study was to investigate the effect of sleep and salivary glucose levels on the development of gingivitis in a prospective longitudinal study of Kuwaiti children. Data were collected from 10-y-old children ( N = 6,316) in 2012 and again in 2014. Children were approximately equally distributed from 138 elementary schools representing the 6 governorates of Kuwait. Calibrated examiners conducted oral examination, self-reported sleep evaluation interviews, anthropomorphic measurements, and unstimulated whole saliva sample collection. Salivary glucose levels were measured by a florescent glucose oxidase method; values of salivary glucose ≥1.13 mg/dL were defined as high glucose levels. A multilevel random intercept and slope analysis was conducted to determine the relationship between sleep duration and gingivitis on 3 levels: within schools, among children, and over time. The outcome was the progression of the extent of gingival inflammation in children over time. The main independent variables were the number of daily sleep hours and salivary glucose levels. Other explanatory variables and confounders assessed were governorate, dental caries and restorations, and obesity by waist circumference (adjusted for snacking and sex). Gingivitis increased over time in children who had shorter sleep duration ( P 1.13 mg/dL predicted gingivitis ( P gingivitis ( P gingivitis and obesity. The level of gingivitis was different among the 6 governorates of Kuwait. Additionally, there was a strong clustering effect of the observations within schools and among children across time. Longitudinal analysis of 6,316 Kuwaiti children revealed that shorter sleep duration and higher salivary glucose levels were both associated with increased gingival inflammation.

    Predictive modeling of human disease based on the microbiota holds great potential yet remains challenging. Here, 50 adults underwent controlled transitions from naturally occurring gingivitis, to healthy gingivae (baseline), and to experimental gingivitis (EG). In diseased plaque microbiota, 27 bacterial genera changed in relative abundance and functional genes including 33 flagellar biosynthesis-related groups were enriched. Plaque microbiota structure exhibited a continuous gradient along the first principal component, reflecting transition from healthy to diseased states, which correlated with Mazza Gingival Index. We identified two host types with distinct gingivitis sensitivity. Our proposed microbial indices of gingivitis classified host types with 74% reliability, and, when tested on another 41-member cohort, distinguished healthy from diseased individuals with 95% accuracy. Furthermore, the state of the microbiota in naturally occurring gingivitis predicted the microbiota state and severity of subsequent EG (but not the state of the microbiota during the healthy baseline period). Because the effect of disease is greater than interpersonal variation in plaque, in contrast to the gut, plaque microbiota may provide advantages in predictive modeling of oral diseases.

    Aging may negatively affect gingival wound-healing. However, little is known about the mechanisms underlying this phenomenon. The present study examined the cellular responses associated with gingival wound-healing in aging. Primary cultures of human gingival fibroblasts were obtained from healthy young and aged donors for the analysis of cell proliferation, cell invasion, myofibroblastic differentiation, and collagen gel remodeling. Serum from young and old rats was used to stimulate cell migration. Gingival repair was evaluated in Sprague-Dawley rats of different ages. Data were analyzed by the Mann-Whitney and Kruskal-Wallis tests, with a p value of .05. Fibroblasts from aged donors showed a significant decrease in cell proliferation, migration, Rac activation, and collagen remodeling when compared with young fibroblasts. Serum from young rats induced higher cell migration when compared with serum from old rats. After TGF-beta1 stimulation, both young and old fibroblasts demonstrated increased levels of alpha-SMA. However, alpha-SMA was incorporated into actin stress fibers in young but not in old fibroblasts. After 7 days of repair, a significant delay in gingival wound-healing was observed in old rats. The present study suggests that cell migration, myofibroblastic differentiation, collagen gel remodeling, and proliferation are decreased in aged fibroblasts. In addition, altered cell migration in wound-healing may be attributable not only to cellular defects but also to changes in serum factors associated with the senescence process. © International & American Associations for Dental Research.

    Studies on gingivitis in children and adolescents are scarce and the results are inconclusive. The aim of this study was to assess the prevalence and extension of gingivitis and associated factors in Brazilian schoolchildren. Cross-sectional data from 1,211 schoolchildren 8 to 12 years old from Southern Brazil in 20 public and private schools were analyzed. Socioeconomic, demographic, and oral hygiene habits were assessed by questionnaires answered by parents and children. Buccal examination assessed presence of plaque, crowding, and gingivitis. Data were analyzed using Poisson regression [prevalence ratio (PR); 95% confidence interval (CI)]. Prevalence of visible plaque was 89.7% (95% CI 88.0-91.3) and gingival bleeding on probing was 78.4% (95% CI 76.1-81.0). The mean and median numbers of sites with gingival bleeding were 3.10 and 2 (SD ± 3.22), respectively. In multivariate adjusted analysis, the presence of a greater number of sites with plaque was significantly associated with gingivitis (PR 1.26; 95% CI 1.07-1.47) and its extension (PR 1.96; 95% CI 1.53-2.51). Lighter-skinned black children had a lower probability of having severe gingivitis (PR 0.69; 95% CI 0.48-0.98) compared with white children. This association was observed after adjusting for other variables. Gingivitis was associated with higher number of sites with plaque and with skin color, reflecting the influence of biological and demographic factors on this oral condition. © 2012 American Association of Public Health Dentistry.

    Hand injuries are very common in sports, such as skiing and ball sports. One of the major reasons causing hand and finger deformity is due to ligament and tendon injury. The aim of this study was to investigate if the high-resolution 3T magnetic resonance imaging (MRI) can demonstrate the complex anatomy of the fingers and thumb, especially the tendons and ligaments, and provide the accurate diagnosis of clinically important fingers and thumbs deformity due to ligamentous and tendinous injuries during sport activities. Sixteen fresh un-embalmed cadaveric hands were harvested from eight cadavers. A total of 20 healthy volunteers' hands and 44 patients with fingers or thumb deformity due to sports-related injuries were included in this study. All subjects had MR examination with T1-weighted images and proton density-weighted imaging with fat suppression (PD FS) in axial, coronal, and sagittal plane, respectively. Subsequently, all 16 cadaveric hands were sliced into 2-mm thick slab with a band saw (six in coronal plane, six in sagittal plane, and four in axial plane). The correlation of anatomic sections and the MRI characteristics of tendons of fingers and the ulnar collateral ligament (UCL) at the metacarpal phalangeal joint (MCPJ) of thumb between 20 healthy volunteers and 44 patients (confirmed by surgery) were analyzed. The normal ligaments and tendons in 16 cadaveric hands and 20 volunteers' hands showed uniform low-signal intensity on all the sequences of the MRI. Among 44 patients with tendinous and ligamentous injuries in the fingers or thumb, 12 cases with UCL injury at MCPJ of the thumb (Stener lesion = 8 and non-Stener lesion = 4), 6 cases with the central slip injury, 12 cases with terminal tendon injury, and 14 cases with flexor digitorum profundus injury. The ligaments and tendons disruption manifested as increased signal intensity and poor definition, discontinuity, and heterogeneous signal intensity of the involved ligaments and tendons. Sports

    Full Text Available Plasma cell granuloma, also known as inflammatory pseudotumor is a tumor-like lesion that manifests primarily in the lungs. But it may occur in various other anatomic locations like orbit, head and neck, liver and rarely in the oral cavity. We here report an exceedingly rare case of gingival plasma cell granuloma in a 58 year old woman who presented with upper gingival polypoidal growth. The histopathological examination revealed a mass composed of proliferation of benign spindle mesenchymal cells in a loose myxoid and fibrocollagenous stroma along with dense infiltrate of chronic inflammatory cells predominantly containing plasma cells. Immunohistochemistry for kappa and lambda light chains showed a polyclonal staining pattern confirming a diagnosis of plasma cell granuloma.

    Most ballet dancers will suffer at least one injury a year. There are numerous causes of injury in dance, and while many investigators have documented risk factors such as anatomical characteristics, past medical history, menstrual history, dance experience, length of dance training, fatigue, and stress, risk factors related to body characteristics and nutrient intake, levels of conditioning, or physical fitness parameters have only recently received the same amount of attention. The aim of the present study was, therefore, to investigate correlations between ballet injury and body fat percentage, active and passive flexibility, lower limb power, upper body and core endurance, and aerobic capacity. Low levels of aerobic fitness were significantly associated with many of the injuries sustained over a 15-week period (r=.590, p=0.034), and body fat percentage was significantly associated with the length of time a dancer was forced to modify activity due to injury (r=-.614, p=0.026). This information may be of benefit to dancers, teachers, physical therapists and physicians in dance schools and companies when formulating strategies to prevent injury.

    Pregnant women demonstrate increases in gingivitis despite similar plaque levels to non-pregnant counterparts. To evaluate an intensive protocol aimed at reducing gingivitis in pregnant women and provide pilot data for large-scale randomized controlled trials investigating oral hygiene measures to reduce pregnancy gingivitis and alter maternity outcomes. One hundred and twenty participants between 16 and 24 weeks gestation with Gingival Index (GI) scores ≥2 at ≥50% of tooth sites were enrolled. Plaque index (PI), gingival inflammation (GI), probing depth (PD), and clinical attachment levels (CAL) were recorded at baseline and 8 weeks. Dental prophylaxis was performed at baseline and oral hygiene instructions at baseline, 4 and 8 weeks. Pregnancy outcomes were recorded at parturition. Mixed-model analysis of variance was used to compare clinical measurements at baseline and 8 weeks. Statistically significant reductions in PI, GI, PD, and CAL occurred over the study period. Mean whole mouth PI and GI scores decreased approximately 50% and the percentage of sites with PI and GI ≥2 decreased from 40% to 17% and 53% to 21.8%, respectively. Mean decreases in whole mouth PD and CAL of 0.45 and 0.24 mm, respectively, were seen. Intensive oral hygiene regimen decreased gingivitis in pregnant patients. © 2013 John Wiley & Sons A/S.

    Full Text Available Introduction: Gingival enlargement (GA is a benign condition of the oral cavity that is characterized by the excessive growth of the gingiva in mass and volume. This lesion is not only caused by hereditary factors or poor oral hygiene, but also by the intake of medications, including antihypertensive, anticonvulsant and immunosuppressive drugs. Objective: To sensitize the prevention or early care in patients with pathologies that merit the use of antihypertensive and anticonvulsants in conjunction with the dentist, to treat or avoid the drug-induced gingival enlargement (DIGE. Materials and methods: A series of clinical cases of patients with gingival enlargement by various drugs are reported, including Phenytoin, Amlodipine and Nifedipine. Periodontal and gingivectomy hygienic phase measures were applied to obtain better effects. Results: Satisfactory results were obtained with a considerable decrease in DIGE. Conclusions: The integral management is important in conjunction with the treating physician to follow up the drug that can be generating gingival enlargement. It is necessary to employ an initial approach with strategies of periodontal hygiene, and in severe cases and, as last resort, the periodontal surgery with gingivectomy and gingivoplasty.

    To examine the prevalence and impact of gingivitis and periodontitis in patients having heart valve surgical procedures. Nationwide Inpatient Sample for the years 2004-2010 was used. All patients who had heart valve surgical procedures were selected. Prevalence of gingivitis/periodontitis was examined in these patients. Impact of gingivitis/periodontitis on hospital charges, length of stay, and infectious complications was examined. 596,190 patients had heart valve surgical procedures. Gingivitis/periodontitis was present in 0.2 percent. Outcomes included: median hospital charges ($175,418 with gingivitis/ periodontitis versus $149,353 without gingivitis/periodontitis) and median length of stay (14 days with gingivitis/periodontitis versus 8 days without gingivitis/periodontitis). After adjusting for the effects of patient- and hospital-level confounding factors, hospital charges and length of stay were significantly higher (p gingivitis/periodontitis compared to their counterparts. Further, patients with gingivitis/periodontitis had significantly higher odds for having bacterial infections (OR = 3.41, 95% CI = 2.33-4.98, p gingivitis/periodontitis. Presence of gingivitis and periodontitis is associated with higher risk for bacterial infections and significant hospital resource utilization.

    Inflammatory periodontal disease is widespread in dogs. This study evaluated site-specific changes in the canine gingival crevicular fluid (GCF) proteome during longitudinal progression from very mild gingivitis to mild periodontitis. Periodontitis diagnosis in dogs requires general anaesthesia with associated risks and costs; our ultimate aim was to develop a periodontitis diagnostic for application in conscious dogs. The objective of this work was to identify potential biomarkers of periodontal disease progression in dogs. Gingival crevicular fluid was sampled from a total of 10 teeth in eight dogs at three different stages of health/disease and samples prepared for quantitative mass spectrometry (data available via ProteomeXchange; identifier PXD003337). A univariate mixed model analysis determined significantly altered proteins between health states and six were evaluated by ELISA. Four hundred and six proteins were identified with 84 present in all samples. The prevalence of 40 proteins was found to be significantly changed in periodontitis relative to gingivitis. ELISA measurements confirmed that haptoglobin was significantly increased. This study demonstrates for the first time that proteins detected by mass spectrometry have potential to identify novel biomarkers for canine periodontal disease. Further work is required to validate additional biomarkers for a periodontitis diagnostic. © 2016 The Authors. Journal of Clinical Periodontology Published by John Wiley & Sons Ltd.

    Full Text Available The lips form the frame of a smile and define the esthetic zone. Excessive gingival display during smile is often referred to as "gummy smile". A successful management of excessive gingival display with lip repositioning procedure has shown excellent results. The procedure involves removing a strip of partial thickness mucosa from maxillary vestibule, then suturing it back to the lip mucosa at the level of mucogingival junction. This technique results in restricted muscle pull and a narrow vestibule, thereby reducing the gingival display. In this case gummy smile was treated by modification of Rubinstein and Kostianovsky′s surgical lip repositioning technique which resulted in a harmonious smile.

    A convenience sample of 60 subjects (27 male; 33 female) with tongue piercings (case group) and 120 subjects (43 male; 77 female) without tongue piercings (control group), ranging in age from 13 to 28 years, were identified from a mix of races living in a geographic area of low socioeconomic status in Brazil. Subjects were recruited from school groups and university centers between January 2008 and March 2009. For each case, 2 controls were selected on a consecutive basis from the same school according to criteria that included age, gender, smoking, and previous orthodontic treatment. Exclusion criteria included individuals with systemic diseases that might compromise the immune system, as well as antibiotics within 3 months or other medications that could affect the gingival tissues. The key study factor was the use or nonuse of tongue piercings (jewelry). The analysis compared periodontal parameters, such as the occurrence, location, and severity of gingival recession, in subjects with and without tongue jewelry. Gingival recession in the anterior lingual mandibular region was assessed as the primary outcome measure. The study sample was divided according to the presence or absence of gingival recession as well as the severity (1-2, 3, and ≥ 4 mm) of gingival recession. The average age of subjects was similar in the case and control groups (18.9 versus 17.7 years, respectively). Fractures of the anterior teeth were present significantly more frequently in cases than controls (26.7% versus 11.7%, respectively; P piercings (OR = 11.0, 95% confidence interval [CI] 5.02-24.09, P <.001). The severity of recession in this region was also significantly higher (calculated using an ordinal scale) in cases than in controls (P < .001). The final multivariate logistic regression model for occurrence of gingival recession included the variables tongue jewelry (yes/no), age, male gender, and the presence of bleeding on probing in the anterior region.

    Full Text Available Background: Gingival recession is the most common and undesirable condition of the gingiva. The aim of study was to investigate the aetiology and severity of gingival recession in a Greek adult population sample. Methods : The study was performed on 165 males and 179 females, 18-68 years old who sought dental treatment in a private dental practice and showed gingival recession. All subjects were clinically examined and answered questions regarding their oral hygiene habits such as the type of toothbrush, frequency of brushing and method of brushing. The association between gingival recession and the following parameters was assessed: plaque score, gingival score and tooth position. Statistical analysis of the results was accomplished using chi-square test (α = 0.05. Results: The majority (79.4% of the patients showed grade I gingival recession and 15.3% showed grade II gingival recession. The maxillary 1 st and 2 nd molars (35.3% and the mandibular 1 st and 2 nd molars (28.7% were the teeth most frequently affected by root surface exposure. Patients with sub-gingival calculus, bacterial plaque and gingival inflammation (P < 0.05, malpositioned teeth (P < 0.001, horizontal brushing method, medium type of toothbrush (P < 0.001 and brushing once daily (P < 0.001 appeared to be the most common precipitating aetiological factor for gingival recession. Conclusion: According to the results of the present study, gingival recession was the result of more than one factor acting together. Horizontal brushing method, usage of medium type toothbrush and tooth brushing once daily were found to be more associated with gingival recession.

    Full Text Available Introduction and aim: In recent decades, many factors such as smoking, unhealthy diet as well as high alcohol intake were marked as risk factors that can lead to increased incidence of malignant alterations, gingivitis, periodontal disease and other oral epithelium pathological changes. Having in mind that in the group of non-malignant and non-dental oral pathology gingivitis and periodontal disease are the most common oral mucosa alterations aim of our research was to investigate histomorphometric characteristics of healthy and altered oral and gingival epithelium. Material and methods: Tissue samples of 24 oral and gingival mucosa specimens were collected. Samples were fixed in 10% buffered paraformaldehyde, routinely processed and embedded in paraffin blocks. From each block sections 5 micrometer thin were made and standard H/E staining as well as immunocytochemical detection of Ki-67 proliferation marker and CD79a lymphocyte marker were performed. Measurements and image analysis was performed with Image Pro Plus software (Media Cybernetics, USA and Axiovision (Ziess, USA. Results: We showed that inflamed gingival epithelium is increasing its thickness in proportion to the severity of adjacent inflammation. Furthermore, mitotic index is rising (up to 132% in the same manner as well as basal lamina length (up to 70% when normal and inflamed gingiva is compared. Architecture of epithelial ridges is changed from straightforward to mesh-like. Conclusion: Assessment of the free gingival epithelium thickness is directly related to the severity of the inflammation process i

    Objectives: To evaluate the prevalence and severity of plaque-induced gingivitis among a Saudi adult population in Riyadh region. Methods: Three hundred and eighty-five eligible participants in this cross-sectional study were recruited from routine dental patients attending the oral diagnosis clinic at Al-Farabi College in Riyadh, Saudi Arabia from June 2013 to December 2013. A clinical examination was performed by 2 dentists to measure the gingival and plaque indices of Löe and Silness for each participant. Results: The prevalence of gingivitis was 100% among adult subjects aged between 18-40 years old. Moreover, the mean gingival index was 1.68±0.31, which indicates a moderate gingival inflammation. In fact, males showed more severe signs of gingival inflammation compared with females (p=0.001). In addition, the mean plaque index was 0.875±0.49, which indicates a good plaque status of the participants. Interestingly, the age was not related either to the gingival inflammation (p=0.13), or to the amount of plaque accumulation (p=0.17). However, males were more affected than females (p=0.005). Conclusion: The results of this study show that plaque accumulation is strongly associated with high prevalence of moderate to severe gingivitis among Saudi subjects. PMID:25399215

    This exploratory randomized, controlled clinical trial sought to evaluate anti-inflammatory and -microbial effects of triclosan during experimental gingivitis as assessed by host response biomarkers and biofilm microbial pathogens. Thirty participants were randomized to triclosan or control dentifrice groups who ceased homecare for 21 days in an experimental gingivitis (EG) protocol. Plaque and gingival indices and saliva, plaque, and gingival crevicular fluid (GCF) were assessed/collected at days 0, 14, 21 and 35. Levels and proportions of 40 bacterial species from plaque samples were determined using checkerboard DNA-DNA hybridization. Ten biomarkers associated with inflammation, matrix degradation, and host protection were measured from GCF and saliva and analysed using a multiplex array. Participants were stratified as "high" or "low" responders based on gingival index and GCF biomarkers and bacterial biofilm were combined to generate receiver operating characteristic curves and predict gingivitis susceptibility. No differences in mean PI and GI values were observed between groups and non-significant trends of reduction of host response biomarkers with triclosan treatment. Triclosan significantly reduced levels of A. actinomycetemcomitans and P. gingivalis during induction of gingivitis. Triclosan reduced microbial levels during gingivitis development (ClinicalTrials.gov NCT01799226). © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Ryb, Gabriel; Dischinger, Patricia; Kerns, Timothy; Burch, Cynthia; Rabin, Joseph; Ho, Shiu

    Research using the National Automotive Sampling System-Crashworthiness Data System (NASS-CDS) suggested a decreased adjusted risk of thoracic aorta injuries (TAI) for newer vehicles during near-side crashes and an increased adjusted TAI risk during frontal crashes. This study attempted to explore possible explanations of these findings. Adult front seat occupants in the Crash Injury Research and Engineering Network (CIREN) database through June 2012 were studied. TAI cases were compared with remaining cases in relation to crash and vehicular characteristics. TAI cases of later crash year (CY) (2004-2012) were compared to those in earlier CY (1996-2003) in relation to TAI severity (minor, moderate, severe and non-survivable). TAI cases in newer model year (MY) vehicles (1999-2012) were compared to those in older vehicles (1988-98) in relation to injury source (steering wheel, front, left, seat belt, air bag and other or unknown). Analysis was stratified by direction of impact (frontal and near-side) and the use of restraints. The similar TAI severity of earlier and later CY among frontal crashes suggests that the observed changes in the adjusted odds of injury seen in NASS-CDS are not due to an increase in injury detection. The decrease in TAI severity among newer vehicles in near-side crashes of later CY is consistent with a beneficial effect of crashworthiness improvements for this crash configuration. A shift of injury source in frontal crashes from the steering wheel in older vehicles to "front of vehicle structures", "seat belts" and "unknown and other" in newer vehicles should suggest potential sites for crashworthiness improvements.

    Gingival samples were histologically evaluated and placed in two groups, 7 samples each. Group 1 was normal gingiva with no or very few inflammatory cells and group 2 was inflamed gingiva with moderately dense accumulation of imflammatory cells in isolated areas, and sparse distribution in other areas. One hundred to three hundred mg gingival tissue samples were separately homogenized in 7 ml of 0.1 M potasssium phosphate buffer (pH 7.4) and incubated with 1.51 x 10 -4 μM of 3 H-estrone in the presence of NADPH at 37 deg for three hours. Organic solvent extracts of the homogenates were separated by silica gel thin layer chromatography and the radioactivity incorporated in estrone (E 1 ) and estradiol-17 β (E 2 ) zones was extracted with methanol and measured by liquid scintillation spectrometry. The rate conversion of (E 1 ) to (E 2 ) in normal and inflamed gingiva was 4.4 and 8.3 x 10 -7 μM/g/min respectively. Prostaglandin E 2 in 3 normal and 2 inflamed gingival samples were 37.8 and 448.7 pmole/g respectively. The significant increase in the biosynthesis of (E 2 ) and PGE 2 in inflamed as compared with normal gingiva could be a systemic factor in aggravating gingival inflammation due to the hyperemic effects of these hormones.

    Full Text Available The width of the attached gingiva is defined as a distance between the depth of the gingival sulcus or gingival/periodontal pocket to the mucogingival junction. Authors suggest that a minimal amount of attached gingiva is necessary to ensure the gingival health. When the buccal bone plate and gingival tissues are thin and the position of the tooth is too vestibular gingival margin often displaces apically, and gingival recession develops. In the presence of gingival recession and reduced vestibular depth oral hygiene procedures are embarrassed.The definition of class III gingival recession is marginal lack of tissue extended to/or beyond the mucogingival junction with bone and soft tissue loss interdentally or malpositioning of the tooth.Prognosis for class III and IV gingival recession is that only partial coverage can be expected after root coverage procedures - FGG (free gingival graft or connective tissue graft (CTG. Adjunctive surgical techniques would be helpful to achieve better aesthetic outcomes.

    Child oral health-related quality of life (COHRQoL) has been increasingly assessed. However, the full relationship between gingivitis and COHRQoL has been assessed by only a small number of studies. This study aims to assess the association between gingival bleeding and how a child perceives its OHRQoL. This cross-sectional study used multistage random sampling to enroll 1,134 12-year-old schoolchildren from Santa Maria, a southern city in Brazil. Participants were examined for gingival bleeding according to the community periodontal index criteria, a full-mouth clinical examination of six sites per tooth. COHRQoL was assessed by the Brazilian version of the Child Perceptions Questionnaire for 11- to 14-Year-Old Children (CPQ11-14), and data on socioeconomic status were collected. Multilevel Poisson regression models fitted the association of gingivitis with overall and domain-specific CPQ11-14 scores. In general, children with bleeding in ≥15% of sites had higher total CPQ11-14 scores and domain-specific scores than their counterparts. This association persisted after adjustment for other potential confounders. The presence and extent of gingival bleeding was associated mainly with emotional limitation domains of the CPQ11-14; those with extended levels of gingivitis had a 1.20 times higher mean score than those with low-level/no gingival bleeding (rate ratio = 1.20; 95% confidence interval = 1.10 to 1.31). The present results indicate that the presence of extensive levels of gingivitis might be negatively associated with how children perceive their oral health and their daily life.

Esta deformidad apical ocasiona generalmente sensibilidad radicular, pobre apariencia estética y lesiones cervicales cariosas por lo que los pacientes pueden preguntar de manera frecuente a los clínicos por procedimientos de recubrimiento radicular. Existen dos grandes grupos de causas de recesión gingival, las que se originan de enfermedad periodontal y de origen traumático, además, se consideran ciertos factores y se les clasifica como factores predisponentes y precipitantes desencadenantes. Patológicamente las recesiones gingivales están ocasionadas por la destrucción de tejido conectivo de la encía, lo cual ocasiona una disminución del flujo sanguíneo a nivel gingival. Se desarrollan varias técnicas con el mismo fin, dentro de estas están el colgajo pediculado, injerto gingival libre, injerto de tejido conectivo y la regeneración tisular guiada. Las condiciones de éxito en el tratamiento de las recesiones gingivales, descansan en el conocimiento de su etiología y de las posibilidades de cicatrización de acuerdo a las diferentes técnicas quirúrgicas consideradas para corregirlas. Los objetivos a considerar en el tratamiento de las recesiones son: mejorar la estética, recubrir las zonas radiculares expuestas y lograr estabilidad clínica.

    Contemporary orthodontic care should be a team approach to achieve health and esthetics of soft and hard tissue. It should be given enough attention that periodontal health provides the foundation for tooth movement, and that distinct esthetic results can be achieved by subtle changes in tooth alignment and gingival contours. Orthodontic treatment planning should include evaluation of gingival health and esthetics to anticipate the need for interdisciplinary approaches. Studies on the effect of orthodontic treatment on gingiva can provides basis for maintaining gingival health and esthetic. This article will focus primarily on the gingival health and esthetic care in orthodontic treatment.

    Periodontal disease pathogenesis has been associated with smoking. Gingivitis is a mild and reversible form of periodontal disease and it tends to progress to periodontitis only in susceptible individuals. In the present study, we aimed to examine the impact of smoking on host responses in gingivitis and to evaluate and compare the inducible nitric oxide synthase (iNOS) activity in gingival tissue and NO and basic fibroblast growth factor (bFGF) levels in the gingival crevicular fluid of patients with gingivitis and healthy individuals. Forty-one participants were assigned to the gingivitis-smoker (n = 13), gingivitis (n = 13), healthy-smoker (n = 7) and healthy groups (n = 8). Clinical indices were recorded; gingival biopsy and gingival crevicular fluid samples were obtained from papillary regions. iNOS expression was evaluated by immunohistochemical staining. The immunoreactive cells were semiquantitatively assessed. For the quantitative determination of nitrite and nitrate in gingival crevicular fluid, the NO assay kit was used. The amount of bFGF in gingival crevicular fluid was determined by enzyme-linked immunosorbent assay. The gingivitis-smoker group demonstrated a stronger iNOS expression than the non-smoker gingivitis group. iNOS expression intensity was lower in the non-smoker healthy group compared to that in healthy-smokers. No significant gingival crevicular fluid NO and bFGF level changes were observed between groups. Among patients with gingivitis, a positive correlation was detected between gingival crevicular fluid NO and bFGF levels (r = 0.806, p = 0.001). Our data suggest that smoking has significant effects on iNOS expression but not on gingival crevicular fluid NO or bFGF levels in healthy and patients with gingivitis. However, our results suggest that bFGF might be involved in the regulation of NO production via iNOS. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2013-06-01

    An individual variation in the gingival inflammatory response to the dental biofilm has been demonstrated. This variability can be observed between individuals with neither quantitative nor qualitative differences in plaque accumulation. The reported significant differences in gingival inflammatory response under quantitatively and/or qualitatively almost identical bacterial challenge suggest that the gingival response to plaque accumulation may be an individual trait, possibly genetic in origin. The most recent classification of periodontal diseases acknowledges that the clinical expression of plaque-induced gingival inflammation can be substantially modified by systemic factors, either inherent to the host or related to environmental influences. The aim of the present literature review is to describe (i) the factors influencing the development of plaque-induced gingivitis as well as (ii) those metabolic, environmental and systemic factors which have a direct impact on the etiopathogenetic pathway of plaque-induced gingivitis, thus altering the nature or course of the gingival inflammatory response to dental biofilm.

    To investigate the incidence of and contributing factors to open gingival embrasures between the central incisors after orthodontic treatment. One hundred posttreatment patients (29 men and 71 women; mean age, 24.7 years) were divided retrospectively into occurrence and nonoccurrence groups based on intraoral photographs. Based on the severity, the occurrence group was further divided into mild, moderate, and severe groups. Parameters from periapical radiographs, superimposed lateral cephalograms, and study models were compared between the occurrence and the nonoccurrence groups by using independent t-tests and were also analyzed on the basis of severity via analysis of variance. Logistic regression analysis was performed to identify the contributing factors to open gingival embrasures. The incidence of open gingival embrasures between the central incisors was 22% and 36% in the maxilla and the mandible, respectively. Lingual movement of the incisors, distance from the contact point to the alveolar crest after treatment, antero-posterior overlap of the two central incisors before treatment in the maxilla, and distance from the contact point to the alveolar crest after treatment in the mandible were significantly associated with the occurrence of open gingival embrasures ( P open gingival embrasures following orthodontic tooth movement is high. Therefore, attention should be paid to the contributing factors to prevent or reduce the occurrence of open gingival embrasures.

    Full Text Available Background: It is a known fact that clinical appearance of gingiva directly correlates with the inflammatory status of the periodontium. It has been observed that the gingival thickness (GT appears to differ in pigmented and nonpigmented gingiva. Thickness of gingiva seems to be of significance and an issue of concern in aesthetic and functional outcome of the periodontal, restorative and orthodontic therapy. So far in the periodontal literature, the gingival width has been discussed to a great extent. GT also plays an equally important role, but it has been given limited importance when compared to gingival width. Purpose of the Study: The purpose of this study was to comparatively assess the GT in pigmented and nonpigmented gingiva by transgingival probing. Materials and Methods: The study included 240 sites in 10 patients each of pigmented and nonpigmented gingiva. The GT was assessed mid-buccally in the attached gingiva, half way between mucogingival junction and free gingival groove and at the base of the interdental papilla. The gingival bleeding index and plaque index were also recorded. The data were statistically analysed using paired t-test and Z-test. Results and Conclusion: Gingival bleeding index and plaque index were similar between both the groups. Both midbuccal and interdental areas were thicker in pigmented gingiva when compared to nonpigmented gingiva.

    Full Text Available Background: The purpose of this study was to quantify some clinical parameters useful as esthetic guidelines when gingival contour is modified and to compare the left and right sides of six maxillary anterior teeth. Materials and Methods: Maxillary casts mounted on an articulator according to the axis orbital plane were photographed from 35 young adults. The angle formed between the gingival line and maxillary midline (GLA and the distance between the gingival zenith of the lateral incisor and the gingival line were measured (LID using a flexible protractor and digital vernier caliper, respectively. The asymmetry was evaluated using a paired t test for the left vs right measurements of GLA and LID. The descriptive statistics for GLA and LID were calculated. Results: The GLA measurements of the left side (86.7΀΁4.2΀ were significantly greater than those of the right side (84.6΀΁5.4΀, and the mean absolute symmetry for GLA was 1.7΀΁4.4΀. The mean LID measurement was 0.92΁0.11. Conclusions: The gingival zenith of the canine is apical to the gingival zenith of the incisors (GLA <90΀ and the gingival zenith of the lateral incisor is below or on (17% the gingival line when head is oriented on the axis orbital plane. A directional asymmetry was shown with the right side higher than the left side. Along with the other parameters related to dental esthetics, these clinical parameters may serve as esthetic guidelines and may enable us to obtain a more predictable outcome.

    Many patients undergo orthodontic treatment for aesthetic improvement. It is well established that the patients who undergo orthodontic treatment have a high susceptibility to present plaque accumulation on their teeth because of the presence of brackets, wires and/or other orthodontic elements on the teeth surfaces with which the oral hygiene procedures might be more difficult. The orthodontic treatment is a double-action procedure regarding the periodontal tissues which may be very meaningful in increasing the periodontal health status and may be a harmful procedure which can be followed by several types of periodontal complications. There is a strong correlation between the severity and extent of gingival recessions and the orthodontic treatment suggesting that orthodontic tooth movement may lead to gingival recession. The principal objective in the treatment of gingival recession is to cover the exposed root surfaces to improve aesthetics and to reduce hypersensitivity. Different soft tissue grafting procedures have been proposed in the treatment of gingival recessions. Subepithelial connective tissue graft is a reliable method for treatment of gingival recession. The purpose of this case report was to illustrate the relationship between orthodontic therapy and gingival recession and to describe the management of this case.

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

    Sheetada is the early stage of periodontal diseases. This occurs due to negligence of oral hygiene, changing life-style, habits, and addictions. It is Kapha Rakta Pradhana Vyadhi. In modern dentistry papillary or marginal gingivitis can be correlated with Sheetada, on the basis of similarities in symptoms, involvement of anatomical structure, etiology and prognosis. The epidemiological studies conducted by American Academy of Periodontology shows that gingivitis of varying severities is nearly universal. It is estimated that over 80% of the world's population suffers from gingivitis. In this clinical study, 106 patients were registered among them 103 completed the treatment and were randomly divided by lottery method into two groups. In Group-A, Dashana Samskara paste local application on gums and in Group-B, Dashana Samskara Choorna Pratisarana on gums was given. After enrollment of the patients in the study cardinal symptoms of Sheetada (gingivitis) such as, Raktasrava, Krishnata, Prakledata, Mriduta, Mukhadaurgandhya, and also the objective criteria such as oral hygiene index, Gingival Index (GI-S), and Gingival Bleeding Index (GBI-S) were studied before and after the treatment. While considering comparative effect on subjective parameters such as Raktasrava, Dantamamsa Shiryamanata, Shotha and Chalata statistically significant results were obtained in Group-A than Group-B. In objective parameters such as, GI-S and GBI-S also showed statistically significant results in Group-A. Observations in follow-up study confirmed that the recurrence rate in the Group-Awas significantly lesser than the Group-B. PMID:24049407

  7. Facial dog bite injuries in children: A case report

    Directory of Open Access Journals (Sweden)

    Alessandro Leite Cavalcanti

    Full Text Available Introduction: Dog bites are common and can affect victims of different ages, from children to the elderly. Injuries are usually located in different body regions, including head and face. The treatment of choice for injuries is the suture of the lesion, accompanied by antibiotic therapy and tetanus and anti-rabies vaccination. Presentation of case: An 11-year-old male black patient was admitted to the Surgery and Maxillo-Facial Traumatology Service, on an urgent basis, victim of domestic animal aggression (dog biting. The child had multiple and extensive lesions on the face, trauma with laceration with loss of substance, involving the left genic region, lower and upper lip, and lower gingival-labial sulcus. Discussion: Smaller children are especially vulnerable to injuries in the craniofacial region due their low stature, propensity to crawl/play on the ground and exploratory behavior. The primary treatment of bites is by means of direct suture, grafting or local flaps, depending on the type of wound and the surgeon's decision, regardless of time elapsed from the attack. Conclusion: This case shows a case of a child patient victim of animal bite, with lesions limited to the region of the face. The patient was followed up for a month and showed good wound healing without any complications. Keywords: Wounds and injuries, Bites and stings, Maxillofacial injuries, Dogs

    The protective mechanisms that maintain periodontal homeostasis in gingivitis and prevent periodontal tissue destruction are poorly understood. The aim of this study was to identify changes in the salivary proteome during experimental gingivitis. We used oral neutrophil quantification and whole saliva (WS) proteomics to assess changes that occur in the inflammatory and resolution phases of gingivitis in healthy individuals. Oral neutrophils and WS samples were collected and clinical parameters measured on days 0, 7, 14, 21, 28, and 35. Increased oral neutrophil recruitment and salivary cytoprotective proteins increased progressively during inflammation and decreased in resolution. Oral neutrophil numbers in gingival inflammation and resolution correlated moderately with salivary β-globin, thioredoxin, and albumin and strongly with collagen alpha-1 and G-protein coupled receptor 98. Our results indicate that changes in salivary cytoprotective proteins in gingivitis are associated with a similar trend in oral neutrophil recruitment and clinical parameters. We found moderate to strong correlations between oral neutrophil numbers and levels of several salivary cytoprotective proteins both in the development of the inflammation and in the resolution of gingivitis. Our proteomics approach identified and relatively quantified specific cytoprotective proteins in this pilot study of experimental gingivitis; however, future and more comprehensive studies are needed to clearly identify and validate those protein biomarkers when gingivitis is active.

    2013-01-01

    Full Text Available Gingival enlargement is a common clinical feature of gingival and periodontal diseases. It is an unwanted side effect of certain systemic drugs given for nondental treatment. It is being reported with three main groups of drugs like calcium channel blockers (CCBs, immunosuppressants, and anticonvulsants. Among calcium channel blockers, nifedipine causes gingival hyperplasia in about 10% of patients, whereas the incidence of amlodipine-, a third generation calcium channel blocker, induced gingival hyperplasia is very limited. There are very few reports of amlodipine-induced gingival enlargement at a dose of 5 mg. We report a case of amlodipine-induced gingival enlargement in a 45-year-old hypertensive patient taking amlodipine at a dose of 5 mg.

    Gingival squamous cell carcinoma have a relatively poor prognosis and large differential diagnosis (periodontitis, osteomyelitis, etc.), therefore, it is usually diagnosed at a late stage. Hematogenous dissemination occurs in only about 10% of cases, including lung (66%), bone (22%), liver (10%), skin, bone marrow and mediastinum. Bone metastases are very rare compared to other malignancies, most commonly affect the axial skeleton (spine, pelvis, ribs and lumbar spine). In our case, we presented a patient with gingival squamous cell carcinoma and bone metastasis in the forearm detected with Whole Body Bone Scintigraphy (WBS), combined with Single Photon Emission Tomography /Computed Tomography (SPECT /CT). The obtained data suggest that the single use of WBS was not informative enough for making the final diagnosis, but the result of combined functional-morphological approach was the most pathognomonic. Thus, with single study can be obtained a complex information, which leads to a fast therapeutic decision. Key words: SPECT/CT. GINGiVAL. SQUAMOUS CELL CARCINOMA

    Full Text Available Abstract Background In daily clinical practice of a dental department it's common to find gingival overgrowth (GO in periodontal patients under treatment with Cyclosporine A (CsA. The pathogenesis of GO and the mechanism of action of Azithromycin (AZM are unclear. A systematic review was conducted in order to evaluate the efficacy of Azithromycin in patients with gingival overgrowth induced by assumption of Cyclosporine A. Methods A bibliographic search was performed using the online databases MEDLINE, EMBASE and Cochrane Central of Register Controlled Trials (CENTRAL in the time period between 1966 and September 2008. Results The literature search retrieved 24 articles; only 5 were Randomised Controlled Trials (RCTs, published in English, fulfilled the inclusion criteria. A great heterogeneity between proposed treatments and outcomes was found, and this did not allow to conduct a quantitative meta-analysis. The systematic review revealed that a 5-day course of Azithromycin with Scaling and Root Planing reduces the degree of gingival overgrowth, while a 7-day course of metronidazole is only effective on concomitant bacterial over-infection. Conclusion Few RCTs on the efficacy of systemic antibiotic therapy in case of GO were found in the literature review. A systemic antibiotic therapy without plaque and calculus removal is not able to reduce gingival overgrowth. The great heterogeneity of diagnostic data and outcomes is due to the lack of precise diagnostic methods and protocols about GO. Future studies need to improve both diagnostic methods and tools and adequate classification aimed to determine a correct prognosis and an appropriate therapy for gingival overgrowth.

    Objective: To determine the frequency of gingival display during smiling and to compare biometric measurements in subjects with and without gingival display. Study Design: Cross-sectional study. Place and Duration of Study: Department of Prosthodontics, Dr. Ishrat-ul-Ibad Khan Institute of Oral Health Sciences, Dow University of Health Sciences, Karachi, from October 2012 to March 2013. Methodology: A total of 275 subjects (121 men and 154 women) were included in this study. The age of the participants ranged between 21 and 65 years. Measurements were carried out using digital caliper. For each participants, the gingival display was judged as either visible or not. The amounts of horizontal and vertical overlap of anterior teeth were measured using a digital caliper. Gender differences in these parameters and the relationship between subjects showing gingival display when smiling and the two intraoral dental biometric measurements were determined. Statistical analyses of data were performed using SPSS version 17.0 software. The mean scores for gender were calculated and a Student's t-test was used to identify significant differences between both groups. Significant level was set to 0.05. Results: A relatively small percentage of the subjects (37.8%) displayed gingiva when smiling. More women significantly displayed gingiva when smiling than men, with a 2:1 female: male ratio. Women had significantly (p=0.001) more horizontal overlap (3.34 +- 1.45 mm) than men (2.90 +- 1.44 mm), although no significant gender difference were found in vertical overlap. Subjects with gingival display had significantly (p < 0.05) more horizontal (3.49 +- 1.36 mm) and vertical (3.26 +- 1.47 mm) overlap of anterior teeth compared to those who did not display gingiva when smiling. Conclusion: Significantly more women displayed gingiva in smiling. Women had significantly more horizontal overlap than men. No gender differences were recorded between vertical overlap.

    Full Text Available Background: The Langerhans cells (LCs are dendritic cells (DCs which belong to the group of antigen presenting cells (APCs. Their function is to recognize the antigen, capture it, and present it to the T lymphocytes; thus initiating an early immune response. The antigen presenting functional LCs may play an important part in initiation and development of gingivitis. The aim of this study was to analyze the density, intraepithelial distribution, and morphology of LCs in gingival epithelium among different age groups with chronic gingivitis and to compare it with that of normal gingiva. Materials and Methods: Immunohistochemistry (IHC was performed to study LCs in normal gingival epithelium (n = 10 and gingival epithelium in chronic gingivitis (n = 30 using anti-CD1a antibody. Mann Whitney U test was performed to compare the density of LCs in normal gingiva with chronic gingivitis. The distribution of LCs in various layers of the epithelium within the three age groups was analyzed using Kruskal-Wallis test. P value less than 0.05 was considered as significant. Results: The density of LCs in chronic gingivitis was significantly higher then that of normal gingiva. Comparing different age groups, the younger individuals had more number of LCs which were located in the superficial layers of gingival epithelium. In chronic gingivitis, higher number of LCs were located in deeper layers when compared with that of normal gingiva. Three morphological types of CD1a positive LCs were observed in normal gingiva, out of which the density of LCs with branched dendritic processes was highest in normal gingiva. Conclusion: The LCs showed variable number, location, and morphology which indicated their adaptation for function in chronic gingivitis.

    Oil pulling or oil swishing therapy is a traditional procedure in which the practitioners rinse or swish oil in their mouth. It is supposed to cure oral and systemic diseases but the evidence is minimal. Oil pulling with sesame oil and sunflower oil was found to reduce plaque related gingivitis. Coconut oil is an easily available edible oil. It is unique because it contains predominantly medium chain fatty acids of which 45-50 percent is lauric acid. Lauric acid has proven anti inflammatory and antimicrobial effects. No studies have been done on the benefits of oil pulling using coconut oil to date. So a pilot study was planned to assess the effect of coconut oil pulling on plaque induced gingivitis. The aim of the study was to evaluate the effect of coconut oil pulling/oil swishing on plaque formation and plaque induced gingivitis. A prospective interventional study was carried out. 60 age matched adolescent boys and girls in the age-group of 16-18 years with plaque induced gingivitis were included in the study and oil pulling was included in their oral hygiene routine. The study period was 30 days. Plaque and gingival indices of the subjects were assessed at baseline days 1,7,15 and 30. The data was analyzed using paired t test. A statistically significant decrease in the plaque and gingival indices was noticed from day 7 and the scores continued to decrease during the period of study. Oil pulling using coconut oil could be an effective adjuvant procedure in decreasing plaque formation and plaque induced gingivitis.

Body mass index (BMI), BMI standard deviation score, and oral cavity (Plaque Index--PLI, Gingival Index--GI, mucosa status, presence and Candida enzymatic activity) were assessed in 96 patients (32 with NS: 30- immunosuppressive treatment, 35--type 1 diabetes, and 29 generally healthy), aged; 3-18 years. Laboratory included cholesterol and triglyceride measurements; in diabetic subjects- glycated haemoglobin, in NS: total protein, albumin, creatinine, haemoglobin, haematocrit, white cell count, urinary protein excretion. Medical records supplied information on disease duration and treatment. A statistical analysis was performed; Kendall Tau coefficient, chi-square test, t-test, and multiple regression analysis ( P Gingivitis occurred more frequently in patients with NS/diabetes. Gingivitis severity was correlated with PLI, age, and yeast enzyme activity in NS--to with immunosuppressive treatment with >1 drug, drug doses, treatment duration, lipid disorders, and BMI; in diabetes, with blood glucose and glycated haemoglobin >8%. Poor hygiene control is the main cause of gingivitis. Gingivitis severity is most likely related to age, lipid disorders and increase in body mass. Candida spp., in uncompensated diabetes and in those using immunosuppressive treatment, might intensify plaque-related gingivitis.

  2. Reversal of drug-induced gingival overgrowth by UV-mediated apoptosis of gingival fibroblasts - an in vitro study.

    2018-05-01

    Gingival overgrowth (GO) is an undesirable result of certain drugs like Cyclosporine A (CsA). Histopathology of GO shows hyperplasia of gingival epithelium, expansion of connective tissue with increased collagen, or a combination. Factors such as age, gender, oral hygiene, duration, and dosage also influence onset and severity of GO. One of the mechanisms behind uncontrolled cell proliferation in drug-induced GO is inhibition of apoptotic pathways, with a consequent effect on normal cell turnover. Our objective was to determine if UV photo-treatment would activate apoptosis in the gingival fibroblast component. Human gingival fibroblast cells (HGF-1) were exposed to 200ng/ml or 400ng/ml CsA and maintained for 3, 6, and 9 days, followed by UV radiation for 2, 5, or 10min (N=6). Naïve (no CsA or UV), negative (UV, no CsA), and positive controls (CsA, no UV) were designated. Prior to UV treatment, growth media was replaced with 1M PBS to prevent absorption of UV radiation by serum proteins, and cells were incubated in growth media for 24h post-UV before processing for TUNEL assay, cell proliferation assays, or immunofluorescence. Data showed a temporal increase in proliferation of HGF-1 cells under the influence of CsA. The 200ng/ml dose was more effective in causing over-proliferation. UV treatment for 10min resulted in significant reduction in cell numbers, as evidenced by counts and proliferation assays. Our study is a first step to further evaluate UV-mediated apoptosis as a mechanism to control certain forms of GO. Copyright © 2018 Elsevier GmbH. All rights reserved.

    The present study assessed the effect of smoking on clinical, microbiological and immunological parameters in an experimental gingivitis model. Twenty-four healthy dental students were divided into two groups: smokers (n = 10); and nonsmokers (n = 14). Stents were used to prevent biofilm removal during brushing. Visible plaque index (VPI) and gingival bleeding index (GBI) were determined 5- on day -7 (running phase), baseline, 21 d (experimental gingivitis) and 28 d (resolution phase). Supragingival biofilm and gingival crevicular fluid were collected and assayed by checkerboard DNA-DNA hybridization and a multiplex analysis, respectively. Intragroup comparison was performed by Friedman and Dunn's multiple comparison tests, whereas the Mann-Whitney U-test was applied for intergroup analyses. Cessation of oral hygiene resulted in a significant increase in VPI, GBI and gingival crevicular fluid volume in both groups, which returned to baseline levels 7 d after oral hygiene was resumed. Smokers presented lower GBI than did nonsmokers (p gingival inflammation after supragingival biofilm accumulation, but smokers had less bleeding, higher proportions of periodontal pathogens and distinct host-response patterns during the course of experimental gingivitis. © 2016 John Wiley & Sons A/S.

    Full Text Available Plasma cell gingivitis is a rare condition characterized by diffuse and massive infiltration of plasma cells into the sub-epithelial connective tissue. Clinically, it appears as a diffuse reddening and edematous swelling of the gingiva with a sharp demarcation along the mucogingival border. Though considered as a hypersensitive reaction to an allergen, the etiology of this bizarre condition is still not properly understood. Here, we present an interesting case of plasma cell gingivitis associated with an enlarged and fissured upper lip, which is quite a rarity. The condition was diagnosed based on clinical and histopathologic findings and treated by gingivectomy. The associated cheilitis has dramatically reduced after treatment of the gingival lesion.

    Full Text Available Necrotizing ulcerative gingivitis is a relatively uncommon periodontal disease, characterized by ulceration, necrosis, pain and gingival bleeding. Factors often related to its occurrence include stress and systemic viral infections, such as those caused by cytomegalovirus and Epstein-Barr virus type 1, the latter being also considered the causative agent of infectious mononucleosis. This article aims to describe a clinical case of a female patient who presented with necrotizing ulcerative gingivitis associated with a clinical picture of infectious mononucleosis, as well as to review the literature concerning a possible correlation between these pathologies. This patient presented to our health care facility with necrotizing ulcerative gingivitis accompanied by lymphadenopathy, fever and prostration, after laboratory tests, Epstein-Barr virus type 1 infection was confirmed, as well as the co-occurrence of pathologies: necrotizing ulcerative gingivitis and infectious mononucleosis. Symptom remission in both disorders also occurred concomitantly, after instruction in plaque control measures and palliative medication for control of systemic symptoms. Therefore, although there is no scientific validation of an association between these two pathologies, it is imperative that all diagnostic alternatives be considered and investigated, in order to establish the therapeutic approach most appropriate to the patient.La gingivitis ulcerativa necrótica es una enfermedad periodontal no común caracterizada por ulceración, necrosis, dolor y sangrado gingival.

    Polyhexamethylene guanidine phosphate (PHMG-P) was compared to chlorhexidine (CHX) in order to determine potential cytotoxic and immune-modulatory effects on human gingival fibroblasts. Cytotoxic effects of PHMG-P and CHX on human gingival fibroblasts were assessed using cell viability assay at various time points and concentrations. The effects of PHMG-P and CHX on the secretion of prostaglandin (PG) E 2 , interleukin (IL)-6, IL-8 and matrix metalloproteinase (MMP)-1 by non-stimulated or IL-1β stimulated fibroblasts were evaluated by enzyme-linked immunosorbent assays. PHMG-P concentration 0.00009% led to the total loss of fibroblast viability within 24 h, whereas inhibition of fibroblast viability by CHX occurred at significantly higher concentrations of 0.0009% (p PHMG-P led to loss of fibroblast viability after 5 min, whilst cells exposed to 0.005% CHX survived 30 min of treatment (p PHMG-P or CHX at concentrations of 0.000045 or 0.0.00009% resulted in significantly decreased PGE 2 , IL-6, IL-8 and MMP-1 levels. PHMG-P or CHX alone did not affect the baseline secretion of PGE 2 , IL-6, IL-8 or MMP-1 by gingival fibroblasts. Cytotoxic effects on gingival fibroblasts were triggered by both PHMG-P and CHX at concentrations below those used in clinical practice. The tested antiseptics did not cause inflammation and reduced IL-1β-induced secretion of inflammatory mediators and collagenase by gingival fibroblasts, which suggests anti-inflammatory properties.

    This study was performed in order to evaluate in vivo the applicability of Laser Doppler Flowmetry (LDF) in recording the gingival blood flow and to assess the changes of gingival blood flow following gingival reshaping performed with Er:YAG and 980 nm diode lasers. The LDF evaluation was performed on 20 anterior teeth, which underwent reshaping of gingiva, corresponding to 5 female patients (4 anterior teeth/patient), aged between 20 and 35. One part of the mouth was treated with Er:YAG laser (LP, VLP modes, 140 - 250 mJ, 10 - 20 Hz, using cylindrical sapphire tips) and other part with 980 nm diode laser (CW, 4 W, contact mode and saline solution cooling). The gingival blood flow was monitored using a MoorLab laser Doppler equipment (Moor Instruments Ltd., Axminster, UK) with a straight optical probe, MP3b, 10 mm. The data were processed using statistical analysis software SPSS v16.0.1. The investigation showed an evident decrease in perfusion for both areas in comparison with the baseline values 24 hours after treatment. The microvascular blood flow increased significantly after 7 days in both areas but mostly in diode area (pdiode area remained at a high level after 14 days. Both lasers proved efficiency in the surgical treatment of gingival tissue. Moreover, Laser Doppler Flowmetry is adequate for recording changes in gingival blood flow following periodontal surgery.

    Fifteen young adult dogs were divided into three groups representing 0, 7- and 21-day healing periods. Randomly selected cuspid teeth were used to compare cord gingival displacement and gingitage techniques for subgingival tooth preparation and impression making. Clinical and histologic measurements were used as a basis for comparison. Results indicate that (1) the experimental teeth were clinically healthy at the beginning of the experiment, (2) clinical health of the gingival tissues was controlled throughout the course of the experiment, and (3) within this experimental setting, there was no significant difference between the cord gingival displacement technique and the gingitage technique.

    A randomized, double-blind, controlled clinical trial was conducted to evaluate the effectiveness of a propolis rinse on induced gingivitis by using the co-twin study design. Twenty-one twin pairs (n=42) were enrolled in a gingivitis study with oral hygiene promotion (14 days) and gingivitis induction (21 days). During the gingivitis induction phase, one member of the twin pair was randomly assigned to a 2% typified propolis rinse, and the other was assigned a color-matched 0.05% sodium fluoride plus 0.05% cetylpyridinium chloride rinse (positive control). Patients rinsed twice daily with 20 mL for 30 seconds for 21 days. Gingivitis was measured on days -14 (baseline), 0 (after hygiene phase), and 21 (after no-hygiene phase) by using the Papillary Bleeding Score (PBS) and by standard digital imaging of the gum tissues (G-parameter). The 38 persons who completed the study (age 13-22 years) were well balanced according to PBS at baseline and G-parameter after the initial hygiene phase. After 21 days without oral hygiene, the propolis rinse and positive control rinse groups did not differ significantly for average PBS measurements or G-parameter. Use of a 2% typified propolis rinse was equivalent to a positive control rinse during a 21-day no-hygiene period.

    Full Text Available Abstract Background Microbial communities inhabiting human mouth are associated with oral health and disease. Previous studies have indicated the general prevalence of adult gingivitis in China to be high. The aim of this study was to characterize in depth the oral microbiota of Chinese adults with or without gingivitis, by defining the microbial phylogenetic diversity and community-structure using highly paralleled pyrosequencing. Methods Six non-smoking Chinese, three with and three without gingivitis (age range 21-39 years, 4 females and 2 males were enrolled in the present cross-sectional study. Gingival parameters of inflammation and bleeding on probing were characterized by a clinician using the Mazza Gingival Index (MGI. Plaque (sampled separately from four different oral sites and salivary samples were obtained from each subject. Sequences and relative abundance of the bacterial 16 S rDNA PCR-amplicons were determined via pyrosequencing that produced 400 bp-long reads. The sequence data were analyzed via a computational pipeline customized for human oral microbiome analyses. Furthermore, the relative abundances of selected microbial groups were validated using quantitative PCR. Results The oral microbiomes from gingivitis and healthy subjects could be distinguished based on the distinct community structures of plaque microbiomes, but not the salivary microbiomes. Contributions of community members to community structure divergence were statistically accessed at the phylum, genus and species-like levels. Eight predominant taxa were found associated with gingivitis: TM7, Leptotrichia, Selenomonas, Streptococcus, Veillonella, Prevotella, Lautropia, and Haemophilus. Furthermore, 98 species-level OTUs were identified to be gingivitis-associated, which provided microbial features of gingivitis at a species resolution.

    The aim of the present study was to evaluate the efficacy of triphala mouth rinse (aqueous) in the reduction of plaque and gingivitis among children. The study was a randomized, double-blinded, controlled trial, with a total of 60 school children (n = 30 in each group; triphala and chlorhexidine groups). Plaque and gingival indices were used to evaluate baseline and follow-up plaque and gingivitis. A total of 57 children completed the study. Both chlorhexidine and triphala groups showed significantly lower mean gingival and plaque index scores at follow up than baseline (P gingival index between the two groups (P = 0.826). The percentage change in the mean plaque index was significantly higher in the chlorhexidine group compared to the triphala group (P = 0.048). The effectiveness of triphala in the reduction of plaque and gingivitis was comparable to chlorhexidine, and can be used for short-term purposes without potential side-effects. It is a cost-effective alternative in reducing plaque and gingivitis. © 2014 Wiley Publishing Asia Pty Ltd.

    This study evaluated the clinical diagnosis of proximal gingivitis by comparing two methods: dental flossing and the gingival bleeding index (GBI). One hundred subjects (aged at least 18 years, with 15% of positive proximal sites for GBI, without proximal attachment loss) were randomized into five evaluation protocols. Each protocol consisted of two assessments with a 10-minute interval between them: first GBI/second floss, first floss/second GBI, first GBI/second GBI, first tooth floss/second floss, and first gum floss-second floss. The dental floss was slid against the tooth surface (TF) and the gingival tissue (GF). The evaluated proximal sites should present teeth with established point of contact and probing depth ≤ 3mm. One trained and calibrated examiner performed all the assessments. The mean percentages of agreement and disagreement were calculated for the sites with gingival bleeding in both evaluation methods (GBI and flossing). The primary outcome was the percentage of disagreement between the assessments in the different protocols. The data were analyzed by one-way ANOVA, McNemar, chi-square and Tukey's post hoc tests, with a 5% significance level. When gingivitis was absent in the first assessment (negative GBI), bleeding was detected in the second assessment by TF and GF in 41.7% (p gingivitis in the second assessment (negative GBI), TF and GF detected bleeding in the first assessment in 38.9% (p = 0.004) and 58.3% (p gingivitis than GBI.

    Full Text Available A smile expresses a feeling of joy, success, sensuality, affection and courtesy, and reveals self confidence and kindness. The harmony of the smile is determined not only by the shape, the position and the color of the teeth but also by the gingival tissues. Gingival health and appearance are essential components of an attractive smile. Gingival pigmentation results from melanin granules, which are produced by melanoblasts. The degree of pigmentation depends on melanoblastic activity. Although melanin pigmentation of the gingiva is completely benign and does not present a medical problem, complaints of ′black gums′ are common particularly in patients having a very high smile line (gummy smile. For depigmentation of gingiva different treatment modalities have been reported like- Bur abrasion, scraping, partial thickness flap, cryotherapy, electrosurgery and laser. In the present case series bur abrasion, scraping, partial thickness flap (epithelial excision cryotherapy and electrosurgery have been tried for depigmentation, which are simple, effective and yield good results, along with good patient satisfaction. The problems encountered with some of these techniques have also been discussed.

  1. Drug-induced liver injury due to antibiotics.

    Science.gov (United States)

    Björnsson, Einar S

    Drug-induced liver injury (DILI) is an important differential diagnosis in patients with abnormal liver tests and normal hepatobiliary imaging. Of all known liver diseases, the diagnosis of DILI is probably one of the most difficult one to be established. In all major studies on DILI, antibiotics are the most common type of drugs that have been reported. The clinical phenotype of different types of antibiotics associated with liver injury is highly variable. Some widely used antibiotics such as amoxicillin-clavulanate have been shown to have a delayed onset on liver injury and recently cefazolin has been found to lead to liver injury 1-3 weeks after exposure of a single infusion. The other extreme is the nature of nitrofurantoin-induced liver injury, which can occur after a few years of treatment and lead to acute liver failure (ALF) or autoimmune-like reaction. Most patients with liver injury associated with use of antibiotics have a favorable prognosis. However, patients with jaundice have approximately 10% risk of death from liver failure and/or require liver transplantation. In rare instances, the hepatoxicity can lead to chronic injury and vanishing bile duct syndrome. Given, sometimes very severe consequences of the adverse liver reactions, it cannot be over emphasized that the indication for the different antibiotics should be evidence-based and symptoms and signs of liver injury from the drugs should lead to prompt cessation of therapy.

    Full Text Available Plaque induced gingival enlargement is most commonly seen and when encountered simultaneously with erosive lichen planus poses a challenge to the treating dentist. Prognosis of one condition may influence the prognosis of another condition. The presented case highlights the significance of proper diagnosis and the management of simultaneously occurring gingival lesions. A 49-year-old hypertensive female presented with painful enlarged bleeding and suppurating gums with burning sensation on eating food along with long-term usage of antihypertensive drug amlodipine known for its gingival enlargement effect. All these multiple factors led to diagnostic dilemma. Effective management of the gingival enlargement was done by using electrocautery to rehabilitate the functions and esthetics of the patient. Gingival condition was also complicated by the presence of coexisting lichen planus which was predominantly erosive for which topical corticosteroid, antifungal, and antimicrobial agents were prescribed. Eight-month follow-up did not show recurrence of gingival enlargement. Electrocautery is an effective tool for the gingivectomy in severe inflammatory type of gingival enlargement because of rapid postoperative hemostasis. For the management of erosive lichen planus, long-term use of topical corticosteroids is an effective approach. Maintenance of oral hygiene and regular follow-ups are essential for these conditions.

    To assess gingival recession (GR) in manual and power toothbrush users and evaluate the relationship between GR and gingival abrasion scores (GA). This was an observational (cross-sectional), single-centre, examiner-blind study involving a single-brushing exercise, with 181 young adult participants: 90 manual brush users and 91 oscillating-rotating power brush users. Participants were assessed for GR and GA as primary response variables. Secondary response variables were the level of gingival inflammation, plaque score reduction and brushing duration. Pearson correlation was used to describe the relationship between number of recession sites and number of abrasions. Prebrushing (baseline) and post-brushing GA and plaque scores were assessed and differences analysed using paired tests. Two-sample t-test was used to analyse group differences; ancova was used for analyses of post-brushing changes with baseline as covariate. Overall, 97.8% of the study population had at least one site of ≥1 mm of gingival recession. For the manual group, this percentage was 98.9%, and for the power group, this percentage was 96.7% (P = 0.621). Post-brushing, the power group showed a significantly smaller GA increase than the manual group (P = 0.004); however, there was no significant correlation between number of recession sites and number of abrasions for either group (P ≥ 0.327). Little gingival recession was observed in either toothbrush user group; the observed GR levels were comparable. Lower post-brushing gingival abrasion levels were seen in the power group. There was no correlation between gingival abrasion as a result of brushing and the observed gingival recession following use of either toothbrush. © 2014 The Authors International Journal of Dental Hygiene Published by John Wiley & Sons Ltd.

    Previous studies of the effects of nicotine on fibroblasts have reported an altered morphology and attachment of fibroblasts to substrates and disturbances in protein synthesis and secretion. This altered functional and attachment response may be associated with changes in the cell membrane resulting from binding of the nicotine, or to disturbances in cell metabolism as a result of high intracellular levels of nicotine. The purpose of the present study, therefore, was to (1) determine whether gingival fibroblasts bound nicotine and if any binding observed was specific or non-specific in nature; (2) determine whether gingival fibroblasts internalized nicotine, and if so, at what rate; (3) determine whether gingival fibroblasts also released nicotine back into the extracellular environment; and (4) if gingival fibroblasts release nicotine intact or as a metabolite. Cultures of gingival fibroblasts were prepared from gingival connective tissue biopsies. Binding was evaluated at 4 degree C using a mixture of 3 H-nicotine and unlabeled nicotine. Specific binding was calculated as the difference between 3 H-nicotine bound in the presence and absence of unlabeled nicotine. The cells bound 1.44 (+/- 0.42) pmols/10(6) cells in the presence of unlabeled nicotine and 1.66 (+/- 0.55) pmols/10(6) cells in the absence of unlabeled nicotine. The difference was not significant. Uptake of nicotine was measured at 37 degree C after treating cells with 3 H-nicotine for time periods up to 4 hours. Uptake in pmols/10(6) cells was 4.90 (+/- 0.34) at 15 minutes, 8.30 (+/- 0.75) at 30 minutes, 12.28 (+/- 2.62) at 1 hour and 26.31 (+/- 1.15) at 4 hours

The current study evaluated the effect of phenytoin on the regulation of collagen, lysyl oxidase and elastin in gingival fibroblasts.Normal human gingival fibroblasts (HGFs were obtained from 4 healthy children and 4 adults. Samples were cultured with phenytoin. MTT test was used to evaluate the proliferation and ELISA was performed to determine the level of IL1β and PGE2 production by HGFs. Total RNA of gingival fibroblasts was extracted and RT-PCR was performed on samples. Mann-Whitney U test was used to analyze the data with an alpha error level less than 0.05.There was a significant difference in the expression of elastin between the controls and treated samples in both adult and pediatric groups and also in the lysyl oxidase expression of adult controls and treated adults. No significant difference was found between collagen expression in adults.The significant difference in elastin and lysyl oxidase expression between adult and pediatric samples indicates the significant effect of age on their production.

    The relationship between dental plaque and gingivitis was verified. Nonspecific gingivitis is an inflammatory process, frequently caused by enzymes and toxins liberate by bacteria form dental plaque. Loose plaque has come under a great deal of investigation because of its role in attachment loss. The current methods used in the treatment of non specific gingivitis encompass the use of antibiotics and conventional surgical techniques. Treating gingivitis with laser energy may further reduce the gingival inflammation and decrease the wound healing time. The lack of correlation between the quantity of dental plaque and the intensity of gingivitis determined us to study the effect of Nd:YAG pulsed laser in reduction of gingival inflammation and wound healing. The aim of this work is to evaluate clinically the anti- inflammatory and wound healing effect of pulsed Nd:YAG laser and to compare the appearance and the levels of the bacteria in the supergingival and subgingival plaque in adolescents with tooth crowding after Nd:YAG laser. The experimental procedure consisted of a clinical and bacteriological study which was undertaken in 20 patients presenting moderate gingivitis. A group of 10 patients was the subject of a bacteriological study and the other group of 10 was used for clinical and histological examination. For each group the clinical criteria of evaluation were: the gingival index, papillary bleeding index, spontaneous aches. Each patient was tested before and after laser exposure or conventional therapy for bacteriological analyses. The results prove that early gingivitis exposure to laser registers a decrease of bacterial colony number and absence of loss of attachment as compared to the application of the conventional treatment. Clinical study has shown that the combination of scaling and root planning with laser therapy is enough to provide improvement in clinical indices and reduction in the number of bacterial colonies.

    Xerostomia is a subjective symptom of dryness in the mouth. Although a correlation between xerostomia and oral conditions in the elderly has been reported, there are few such studies in the young adults. The aim of this study was to examine the relationship of xerostomia with the gingival condition in university students. A total of 2077 students (1202 male subjects and 875 female subjects), 18-24 years of age, were examined. The disease activity and severity of the gingival condition were assessed as the percentage of teeth with bleeding on probing (%BOP) and the presence of teeth with probing pocket depth of ≥ 4 mm, respectively. Additional information on xerostomia, oral health behaviors, coffee/tea intake and nasal congestion was collected via a questionnaire. Path analysis was used to test pathways from xerostomia to the gingival condition. One-hundred and eighty-three (8.8%) students responded that their mouths frequently or always felt dry. Xerostomia was related to %BOP and dental plaque formation, but was not related to the presence of probing pocket depth ≥ 4 mm. In the structural model, xerostomia was related to dental plaque formation (p Xerostomia was associated with coffee/tea intake (p Xerostomia was indirectly related to gingival disease activity through the accumulation of dental plaque. Nasal congestion and coffee/tea intake also affected xerostomia. These findings suggest that xerostomia should be considered in screening for gingivitis risk in young adults. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The cytoskeleton is a dynamic structure that plays a key role in maintaining cell morphology and function. This study investigates the effect of bacterial wall lipopolysaccharide (LPS), a strong inflammatory agent, on the dynamics and organization of actin, tubulin, vimentin, and vinculin proteins in human gingival fibroblasts (HGF). A time-dependent study showed a noticeable change in actin architecture after 1.5 h of incubation with LPS (1 microg/ml) with the formation of orthogonal fibers and further accumulation of actin filament at the cell periphery by 24 h. When 0.01-10 microg/ml of LPS was added to human gingival fibroblast cultures, cells acquired a round, flat shape and gradually developed cytoplasmic ruffling. Lipopolysaccharides extracted from Aggregatibacter actinomycetemcomitans periodontopathogenic bacteria promoted alterations in F-actin stress fibres of human gingival cells. Normally, human gingival cells have F-actin fibres that are organized in linear distribution throughout the cells, extending along the cell's length. LPS-treated cells exhibited changes in cytoskeletal protein organization, and F-actin was reorganized by the formation of bundles underneath and parallel to the cell membrane. We also found the reorganization of the vimentin network into vimentin bundling after 1.5 h of treatment. HGF cells exhibited diffuse and granular gamma-tubulin stain. There was no change in LPS-treated HGF. However, vinculin plaques distributed in the cell body diminished after LPS treatment. We conclude that the dynamic and structured organization of cytoskeletal filaments and actin assembly in human gingival fibroblasts is altered by LPS treatment and is accompanied by a decrease in F-actin pools.

    Laser ablation is recently suggested as a most effective and reliable technique for depigmentation of melanin hyperpigmented gingiva. To date, different lasers have been used for gingival depigmentation (CO 2 , diode, Nd:YAG, Er:YAG and Er,Cr:YSGG lasers). The use of Er:YAG laser for depigmentation of melanin hyperpigmented gingiva has gained increasing importance in recent years. The purpose of this study was to report removal of gingival melanin pigmentation using an Er:YAG laser in a literature review. The main outcomes, such as improvement of signs (clinical parameters of bleeding, erythema, swelling and wound healing), symptoms (pain) and melanin recurrence/repigmentation were measured. The literature demonstrated that depigmentation of gingival melanin pigmentation can be performed safely and effectively by Er:YAG laser resulting in healing and an esthetically significant improvement of gingival discoloration. Thus, Er:YAG laser seems to be safe and useful in melanin depigmentation procedure. However, the main issue in giving the final conclusion of the optimal Er:YAG laser use in melanin depigmentation is that, to date, studies are offering completely discrepant Er:YAG laser procedure protocols (complex settings of laser parameters), and different criteria for the assessment of depigmentation and repigmentation (recurrence), thus hampering the comparison of the results. Therefore, further studies are necessary to give an optimal recommendation on the use of Er:YAG laser in gingival melanin hyperpigmentation.

    Full Text Available Star fruit (Avarrhoa carambola is a fruit from oxalidace family. lt is found in many countries of the world including Bangladesh. But its ingestion or drinking star fruit juice may lead to intoxication especially in patients with chronic kidney disease and manifestations might be neurological or nephrological. lt may also cause acute kidney injury in patients with previously normal renal function. Here we are presenting a case who presented with acute kidney injury after star fruit ingestion with previously unknown renal function impairment. The etiology was confirmed by histopathological exami­nation after doing renal biopsy. This renal function impairment is mainly due to oxalate crystal induce nephropathy which is richly abundant in star fruit. His renal function was improved ·with conservative management. Physicians should be alert to consider the ingestion of star fruit as a cause of acute kidney injury in a patient even in the absence of previous renal function impairment.

    The gingival epithelium is the physiologically important interface between the bacterially colonized gingival sulcus and periodontal soft and mineralized connective tissues, requiring protection from exposure to bacteria and their products. However, of the three epithelia comprising the gingival epithelium, the junctional epithelium has much wider intercellular spaces than the sulcular epithelium and oral gingival epithelium. Hence, the aim of the present study was to characterize the cell adhesion structure in the junctional epithelium compared with the other two epithelia. Gingival epithelia excised at therapeutic flap surgery from patients with periodontitis were examined for expression of adhesion molecules by immunofluorescence. In the oral gingival epithelium and sulcular epithelium, but not in the junctional epithelium, desmoglein 1 and 2 in cell-cell contact sites were more abundant in the upper than the suprabasal layers. E-cadherin, the main transmembranous molecule of adherens junctions, was present in spinous layers of the oral gingival epithelium and sulcular epithelium, but was scarce in the junctional epithelium. In contrast, desmoglein 3 and P-cadherin were present in all layers of the junctional epithelium as well as the oral gingival epithelium and sulcular epithelium. Connexin 43 was clearly localized to spinous layers of the oral gingival epithelium, sulcular epithelium and parts of the junctional epithelium. Claudin-1 and occludin were expressed in the cell membranes of a few superficial layers of the oral gingival epithelium. These findings indicated that the junctional epithelium contains only a few desmosomes, composed of only desmoglein 3; adherens junctions are probably absent because of defective E-cadherin. Thus, the anchoring junctions connecting junctional epithelium cells are lax, causing widened intercellular spaces. In contrast, the oral gingival epithelium, which has a few tight junctions, functions as a barrier.

    Full Text Available Lysine-specific gingipain (Kgp is a virulence factor secreted from Porphyromonas gingivalis (P. gingivalis, a major etiological bacterium of periodontal disease. Keratin intermediate filaments maintain the structural integrity of gingival epithelial cells, but are targeted by Kgp to produce a novel cytokeratin 6 fragment (K6F. We investigated the release of K6F and its induction of cytokine secretion.K6F present in the gingival crevicular fluid of periodontal disease patients and in gingipain-treated rat gingival epithelial cell culture supernatants was measured by matrix-assisted laser desorption/ionization time-of-flight mass spectrometer-based rapid quantitative peptide analysis using BLOTCHIP. K6F in gingival tissues was immunostained, and cytokeratin 6 protein was analyzed by immunofluorescence staining and flow cytometry. Activation of MAPK in gingival epithelial cells was evaluated by immunoblotting. ELISA was used to measure K6F and the cytokines release induced by K6F. Human gingival fibroblast migration was assessed using a Matrigel invasion chamber assay.We identified K6F, corresponding to the C-terminus region of human cytokeratin 6 (amino acids 359-378, in the gingival crevicular fluid of periodontal disease patients and in the supernatant from gingival epithelial cells cultured with Kgp. K6F antigen was distributed from the basal to the spinous epithelial layers in gingivae from periodontal disease patients. Cytokeratin 6 on gingival epithelial cells was degraded by Kgp, but not by Arg-gingipain, P. gingivalis lipopolysaccharide or Actinobacillus actinomycetemcomitans lipopolysaccharide. K6F, but not a scrambled K6F peptide, induced human gingival fibroblast migration and secretion of interleukin (IL-6, IL-8 and monocyte chemoattractant protein-1. These effects of K6F were mediated by activation of p38 MAPK and Jun N-terminal kinase, but not p42/44 MAPK or p-Akt.Kgp degrades gingival epithelial cell cytokeratin 6 to K6F that, on

    Full Text Available Background: The development of periodontal disease is influenced by bacteria-plaque, while there are also several factors modifying the host’s response, one of which is psychological stress. Alpha-amylase as a biomarker is also associated with periodontal inflammatory disease. Purpose: The purpose of this study was to examine the difference of alpha-amylase level between gingivitis and periodontitis. Methods: This research constitutes a descriptive study involving 44 subjects, divided into two groups: one of 22 gingivitis subjects and the other of 22 periodontitis subjects. These individuals completed a PSS-14 questionnaire before their levels of alpha salivary amylase were measured by Cocorometer. Data was analyzed by means of a paired T test and a Mann Whitney test with p < 0.05. Results: There were significant differences between the alpha-amylase levels of gingivitis and periodontitis. However, no significant contrast existed in the PSS-14 scores of the two periodontal disease groups. Conclusion: In conclusion alpha-amylase levels in the periodontitis group were higher than those in the gingivitis group and could be used as marker indicators of stress.

    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.

    Gingivitis and lumpy jaw are diseases of polymicrobial aetiology. Although Fusobacterium necrophorum has been associated with these diseases in macropods, little is known about other organisms associated with these diseases in this animal species. PCR-DGGE analysis revealed the potential pathogens associated with gingivitis and lumpy jaw in macropods. PCR-DGGE profile comparison between the healthy and disease groups indicated a shift in the oral bacterial community structures with similarity coefficients of 48% and 35% for gingivitis and lumpy jaw respectively. Moreover, gingivitis was associated with increase in bacterial diversity (Shannon index = 2.87; PL curve = 45%) while lumpy jaw resulted in a decline in bacterial diversity (Shannon index = 2.47; PL curve = 74%). This study suggest that the establishment of gingivitis and lumpy jaw diseases follows the ecological plaque hypothesis. This forms the basis for an expanded investigation in an epidemiological scale and suggests the need for the appropriate choice of antimicrobial agent(s) and for the effective management and control of polymicrobial diseases.

    Leukocyte-platelet rich fibrin belongs to a second generation of platelet concentrates that does not need biochemical blood manipulation. It is used for tissue healing and regeneration in periodontal and oral-maxillofacial surgery. We report two cases of hyperplastic gingival lesions treated by exeresis and application of leukocyte-platelet rich fibrin membranes in order to improve and accelerate tissue healing. Two patients (a 78-year-old Caucasian woman and a 30-year-old Caucasian man) were treated for hyperplastic gingival lesions. They underwent to exeresis of lesions and application of leukocyte-platelet rich fibrin membranes. Tissue healing was clinically evaluated after 1, 3, 7, 14 and 30 postoperative days. No recurrences were observed after 2 years of semi-annual follow up. We obtained rapid and good healing of soft tissues probably due to the elevated content of leukocytes, platelets and growth factors in the leukocyte-platelet rich fibrin. Based on our results we suggest the use of leukocyte-platelet rich fibrin to cover wounds after exeresis of oral neoformations such as hyperplastic gingival lesions.

    This study profiled the local and systemic inflammatory responses to experimentally induced gingivitis. Eight females participated in a 21-day experimental gingivitis model followed by a 14-day resolution phase. Bleeding on probing and plaque index scores were assessed before, during, and after resolution of gingival inflammation, and samples of saliva, GCF, and plasma were collected. Samples were assessed for biomarkers of inflammation using the BioPlex platform and ELISA. There were no significant changes in GCF levels of cytokines during the experimental phase; however, individual variability in cytokine profiles was noted. During resolution, mean GCF levels of IL-2, IL-6, and TNF-α decreased and were significantly lower than baseline levels (P = 0.003, P = 0.025, and P = 0.007, resp.). Furthermore, changes in GCF levels of IL-2, IL-6, and TNF-α during resolution correlated with changes in plaque index scores (r = 0.88, P = 0.004; r = 0.72, P = 0.042; r = 0.79, P = 0.019, resp.). Plasma levels of sICAM-1 increased significantly during the experimental phase (P = 0.002) and remained elevated and significantly higher than baseline levels during resolution (P gingivitis adds to the systemic inflammatory burden of an individual.

    Orthodontic brackets contribute to the accumulation of bacterial plaque on tooth surfaces because they hinder oral hygiene. In contrast to conventional brackets, self-ligating brackets do not require additional parts to support the arches, thus improving dental hygiene. The aim of this study was to compare the gingival response in orthodontic patients wearing self-ligating or conventional brackets. A sample of 22 patients aged 16 to 30 years was divided into two groups: Group A, treated with selfligating brackets (Damon system) and Group B, treated with conventional brackets (Roth technique). The following were assessed during the treatment: Plaque Index (PI), Gingival Index (GI) and Probing Depth (PD), and sub-gingival samples were taken from teeth 14/24 for microbiological observation. No statistically significant difference was found between Groups A and B; p>0.05 (sign-ranked) or between PI, GI and PD at the different times (Friedman's Analysis of Variance), even though the indices were found to increase at 14 days, particularly for self-ligating brackets. The quantity and quality of microorganisms present were compatible with health on days 0, 28 and 56. As from day 14 there is a predominance of microbiota compatible with gingivitis in both groups. In the samples studied, orthodontic treatment increases bacterial plaque and inflammatory gingival response, but gingival-periodontal health can be maintained with adequate basic therapy. Self-ligating and conventional brackets produced similar gingival response.

  8. Leptin and Pro-Inflammatory Stimuli Synergistically Upregulate MMP-1 and MMP-3 Secretion in Human Gingival Fibroblasts.

    Directory of Open Access Journals (Sweden)

    Rachel C Williams

    Full Text Available Gingival fibroblast-mediated extracellular matrix remodelling is implicated in the pathogenesis of periodontitis, yet the stimuli that regulate this response are not fully understood. The immunoregulatory adipokine leptin is detectable in the gingiva, human gingival fibroblasts express functional leptin receptor mRNA and leptin is known to regulate extracellular matrix remodelling responses in cardiac fibroblasts. We therefore hypothesised that leptin would enhance matrix metalloproteinase secretion in human gingival fibroblasts.We used in vitro cell culture to investigate leptin signalling and the effect of leptin on mRNA and protein expression in human gingival fibroblasts. We confirmed human gingival fibroblasts expressed cell surface leptin receptor, found leptin increased matrix metalloproteinase-1, -3, -8 and -14 expression in human gingival fibroblasts compared to unstimulated cells, and observed that leptin stimulation activated MAPK, STAT1/3 and Akt signalling in human gingival fibroblasts. Furthermore, leptin synergised with IL-1 or the TLR2 agonist pam2CSK4 to markedly enhance matrix metalloproteinase-1 and -3 production by human gingival fibroblasts. Signalling pathway inhibition demonstrated ERK was required for leptin-stimulated matrix metalloproteinase-1 expression in human gingival fibroblasts; whilst ERK, JNK, p38 and STAT3 were required for leptin+IL-1- and leptin+pam2CSK4-induced matrix metalloproteinase-1 expression. A genome-wide expression array and gene ontology analysis confirmed genes differentially expressed in leptin+IL-1-stimulated human gingival fibroblasts (compared to unstimulated cells were enriched for extracellular matrix organisation and disassembly, and revealed that matrix metalloproteinase-8 and -12 were also synergistically upregulated by leptin+IL-1 in human gingival fibroblasts.We conclude that leptin selectively enhances the expression and secretion of certain matrix metalloproteinases in human gingival

    Hydrocarbon-induced occupational liver injury is a well-known clinical entity among petroleum industry workers. There are many types of hydrocarbon exposure, with inhalation being the most common. Hydrocarbon-induced occupational liver injury is a rarely suspected and commonly missed etiological agent for liver injury. We report a case of a non-petroleum industry worker with chronic liver disease secondary to hydrocarbon-induced occupational liver injury caused by chronic low-grade hydrocarbon ingestion due to occupational malpractice. A 23-year-old Sri Lankan man who was a motor mechanic presented to our hospital with decompensated cirrhosis. He had been chronically exposed to gasoline via inadvertent ingestion due to occupational malpractice. He used to remove gasoline from carburetors by sucking and failed to practice mouth washing thereafter. On evaluation, he had histologically proven established cirrhosis. A comprehensive history and workup ruled out other nonoccupational etiologies for cirrhosis. The patient's long-term occupational gasoline exposure and clinical course led us to a diagnosis of hydrocarbon-induced occupational liver injury leading to decompensated cirrhosis. Hydrocarbon-induced occupational liver injury should be considered as a cause when evaluating a patient with liver injury with possible exposure in relevant occupations.

    This study was intended to report our recent experience of bladder injuries due to gunshots in the Syrian conflict and review the literature regarding diagnosis and treatment. Twenty-two cases with abdominal and inguinal firearm wounds and bladder ruptures sustained in the Syrian conflict were reported. Age, mechanism/location of damage, associated injuries, Revised Trauma Score (RTS), Injury Severity Score (ISS), Trauma Injury Severity Score (TRISS), and complications were analyzed. The severity of the bladder injuries was classified according to the American Association for the Surgery of Trauma Organ Injury Scaling (AAST-OIS grade ?II database).The type of the bladder rupture was defined according to the classification System for Bladder Injury Based on Findings at CT Cystography. The mean age was 26 years (range, 18-36). The mean ISS was 22 (10-57), mean TRISS was 0.64 (0.004-0.95), and mean RTS was 6.97 (3.30-7.84). In the mortality group, the mean ISS, TRISS, and RTS were 48 (36-57), 0.016 (0.004-0.090), and 4.10 (3.30-4.92), respectively; whereas, the mean ISS, TRISS, and RTS were found as 21 (10-26), 0.64 (0.49-0.95), and 7.24 (5.65-7.84), respectively in the survival group (P=0.06). CT-cystography showed seventeen type 2, three type 4, and two type 5 bladder injuries. According to AAST-OIS, there were nine grade IV, six grade III, five grade II, and two grade V injuries. In war settings, when injuries are often severe and multiple surgical exploration and closure are mandatory, mortality risk is associated with high ISS and low TRISS and RTS values.

    Gingivitis, an inflammation of the gingival tissues, typically progresses to periodontitis. The objective of this study is to estimate the prevalence of gingivitis in 35- to 70-year-olds residing in San Juan, Puerto Rico, and assess the differences in gingivitis distribution between age and gender groups. A cross-sectional epidemiological study was conducted with a sample of patients from a private practice and patients/employees of the Puerto Rico Medical Center. Participants completed a medical history questionnaire and received soft/hard tissue and gingival assessments based on a modified Löe-Silness index. Descriptive statistics were employed to estimate the overall gingivitis prevalence, severity (mild, moderate, severe), and mean gingival index (GI). Bleeding on probing (BOP) prevalence and the mean percentage of BOP sites were calculated by gender and age. Multinomial logistic regression was used to evaluate the associations between age, gender, and severity in 3 categories; multivariate logistic regression was used for having >=40% sites with BOP (vs. having Puerto Rico than in the US.

    Increased C-reactive protein levels have been found in all active inflammations, including periodontitis. This study aims to assess the C-reactive protein levels in periodontal disease progression. Forty-five patients were divided into the following three groups (n=15) based on gingival index, probing pocket depth, and clinical attachment level: healthy (group I), gingivitis (group II), and chronic periodontitis (group III). Gingival crevicular fluid and serum samples were quantified for C-reactive protein using enzyme-linked immunosorbent assay. The mean C-reactive protein concentration in gingival crevicular fluid and serum was found to be highest in group III (1233.33ng/mL for gingival crevicular fluid, 5483.33ng/mL for serum), and least in group I (60 ng/mL and 413 ng/mL for gingival crevicular fluid and serum, respectively) The mean C-reactive protein concentration in group II (453.33ng/mL for gingival crevicular fluid and 3565.33 ng/mL for serum) was found to be intermediate. C-reactive protein levels in gingival crevicular fluid and serum increased proportionately with the severity of periodontal disease. They correlated positively with clinical parameters, including gingival index, probing pocket depth, and clinical attachment level. Thus, it can be considered as a periodontal inflammatory biomarker and deserves further consideration. © 2010 Blackwell Publishing Asia Pty Ltd.

    Abstract Rationale: Hydronephrosis caused by retroperitoneal hematoma after a seatbelt injury is a unique clinical entity. Patient concerns: A 21-year-old man, who had been wearing a seatbelt, was brought to our hospital after a motor vehicle collision, complaining of abdominal pain. Computed tomography (CT) revealed retroperitoneal hematoma in the upper pelvic region. Since he was hemodynamically stable throughout admission, he was managed conservatively. Seventeen days after initial discharge, the patient revisited our emergency department due to right back pain. Diagnoses: CT scans indicated retroperitoneal hematoma growth resulting in hydronephrosis of the right kidney. Interventions: Laparoscopic drainage of the retroperitoneal hematoma was successfully performed. Outcomes: His symptoms resolved after the surgery. Follow-up CT scans three months later demonstrated complete resolution of the hydronephrosis and retroperitoneal hematoma. Lessons: Our case highlights a patient with delayed hydronephrosis because of retroperitoneal hematoma expansion after a seatbelt injury. PMID:29879068

    Full Text Available Background: Acute myeloblastic leukaemia is a malignant bone marrow neoplasm of myeloid precursors of white blood cells. Due to its high morbidity rate, early diagnosis and appropriate medical therapy is essential. Methods: The article highlights normal blood alterations like anaemia, thrombocytopenia, leukocytosis and advanced diagnostic aids like flow cytometry, special staining as a diagnostic modality as well as for prognostic information in acute leukaemia, particularly as a tool for assigning lineage and facilitating further pathologic classification which may be helpful in influencing treatment strategies.Results: On clinical examination the case presented with features of inflammatory gingival enlargement with presence of local deposits and calculus. Routine blood examination anaemia, thrombocytopenia, leukocytosis with haemoglobin 5.6 gm% and total leukocyte count of 1,12,000 / cu mm suggestive of leukaemia. Myeloperoxidase and leukocyte nonspecific esterase (NSE special stain were used which showed presence of myeloblasts in the peripheral smear suggestive of acute myelocytic leukaemia. Flow cytometry were done which further helped in interpretation of these cells which showed to be strongly positive for CD45, CD13, CD14, and anti HLADR and moderately positive for CD4, CD34 and Anti MPO confirming to be case of AML-M4 with 57.73% gating.Conclusions: Fact that gingival alterations are sometimes the first manifestations of the disease implies that dental professionals must be sufficiently familiarized with the clinical manifestations of systemic diseases. The timely referral by the general dentist for a suspicious lesion provided an early diagnosis and early intervention reducing the patient morbidity.

    To evaluate supragingival and subgingival plaque formation on the dentogingival area in smokers and never smokers using the experimental gingivitis model and a plaque scoring system that considers the presence of an area free of plaque between plaque and the gingival sulcus called the plaque free zone (PFZ). Male volunteers, 9 current smokers and 10 never-smokers, refrained from oral hygiene procedures in the maxillary incisors and canines (test teeth) for 25 days. Under conditions of clinically healthy gingiva (phase 1) and gingival inflammation (phase 2), the supragingival plaque formation pattern was observed for 4 days in the dentogingival area. Gingival crevicular fluid was also measured. Plaque was dyed with fucsine and its presence was recorded by a calibrated examiner based on a 3-criteria scoring system: 0 - absence of stained plaque; 1 - presence of stained plaque and supragingival PFZ; 2 - presence of stained plaque and absence of PFZ, indicating that subgingival plaque formation has taken place. In both phases, smokers presented a significantly lower relative frequency of sites with subgingival plaque compared to never-smokers (P smokers demonstrated a significantly lower frequency of gingival bleeding than did non-smokers (23.6% vs 66.1%; P Smokers presented significantly lower percentages of sites with subgingival plaque in all experimental periods and presented less gingival inflammation as shown by GBI and gingival crevicular fluid quantification.

    Full Text Available Hereditary gingival fibromatosis is a rare condition that can occur as an isolated disease or as part of a syndrome or chromosomal abnormality. In severe cases, the gingival enlargement may cover the crowns of teeth and cause severe functional and aesthetic concerns. Here, we present a case of an 8-year-old girl with severe enlargement of gums in maxilla and mandible. Both deciduous and permanent teeth were not erupted in the oral cavity at all. Mutation in the Son-of-Sevenless (SOS-1 gene has been associated with the disease. The diagnosis was made based on clinical examination and family history. Surgical removal of the hyperplastic tissue was performed under general anesthesia.

    Smoking is a major risk factor for destructive periodontal disease. There is limited information with regard to effects of smoking in subjects with minimal periodontal destruction. The aim of the present investigation was to assess the development of gingival recession in young adult smokers and non-smokers. 61 systemically healthy young adults, 19 to 30 years of age completed the final examination. 30 volunteers smoked at least 20 cigarettes per day, whereas 31 subjects were non-smokers. Clinical periodontal conditions were assessed 4x within a time period of 6 months. Site-specific analyses considering the correlated structure of data were performed. At the outset, 50% of subjects presented with gingival recession at 1 or more sites. There was no significant difference in the prevalence of gingival recession between non-smokers and smokers. Severe recession in excess of 2 mm affected about 23% non-smokers but only 7% smokers. Some further gingival recession developed during the 6-month observation period. In a multivariate logistic regression analysis, the risk for recession development appeared not to be influenced by smoking status after adjusting for periodontal probing depth, recession at baseline, tooth brushing frequency, gender, jaw, tooth type and site. Present data did not support the hypothesis that smokers are at an increased risk for the development of gingival recession.

    The presence of inflammatory infiltrates with B cells, specifically plasma cells, is the hallmark of periodontitis lesions. The composition of these infiltrates in various stages of homeostasis and disease development is not well documented. Human tissue biopsies from sites with gingival health (n = 29), gingivitis (n = 8), and periodontitis (n = 21) as well as gingival tissue after treated periodontitis (n = 6) were obtained and analyzed for their composition of B cell subsets. Ag specificity, Ig secretion, and expression of receptor activator of NF-κB ligand and granzyme B were performed. Although most of the B cell subsets in healthy gingiva and gingivitis tissues were CD19(+)CD27(+)CD38(-) memory B cells, the major B cell component in periodontitis was CD19(+)CD27(+)CD38(+)CD138(+)HLA-DR(low) plasma cells, not plasmablasts. Plasma cell aggregates were observed at the base of the periodontal pocket and scattered throughout the gingiva, especially apically toward the advancing front of the lesion. High expression of CXCL12, a proliferation-inducing ligand, B cell-activating factor, IL-10, IL-6, and IL-21 molecules involved in local B cell responses was detected in both gingivitis and periodontitis tissues. Periodontitis tissue plasma cells mainly secreted IgG specific to periodontal pathogens and also expressed receptor activator of NF-κB ligand, a bone resorption cytokine. Memory B cells resided in the connective tissue subjacent to the junctional epithelium in healthy gingiva. This suggested a role of memory B cells in maintaining periodontal homeostasis.

    The free gingival graft (FGG) and connective tissue graft (CTG) are currently considered to be the gold standards for keratinized gingival tissue reconstruction and augmentation. However, these procedures have some disadvantages in harvesting large grafts, such as donor-site morbidity as well as insufficient gingival width and thickness at the recipient site post-treatment. To solve these problems, we focused on an alternative strategy using micronized tissue transplantation (micro-graft). In this study, we first investigated whether transplantation of micronized gingival connective tissues (MGCTs) promotes skin wound healing. MGCTs (≤100 µm) were obtained by mincing a small piece (8 mm 3 ) of porcine keratinized gingiva using the RIGENERA system. The MGCTs were then transplanted to a full skin defect (5 mm in diameter) on the dorsal surface of immunodeficient mice after seeding to an atelocollagen matrix. Transplantations of atelocollagen matrixes with and without micronized dermis were employed as experimental controls. The results indicated that MGCTs markedly promote the vascularization and epithelialization of the defect area 14 days after transplantation compared to the experimental controls. After 21 days, complete wound closure with low contraction was obtained only in the MGCT grafts. Tracking analysis of transplanted MGCTs revealed that some mesenchymal cells derived from MGCTs can survive during healing and may function to assist in wound healing. We propose here that micro-grafting with MGCTs represents an alternative strategy for keratinized tissue reconstruction that is characterized by low morbidity and ready availability. © 2017 Wiley Periodicals, Inc.

    Full Text Available Chitosan hydrogels containing hydroxypropyl methylcellulose (HPMC and toluidine blue O were prepared and assessed for their mucoadhesive property and antimicrobial efficacy of photodynamic inactivation (PDI. Increased HPMC content in the hydrogels resulted in increased mucoadhesiveness. Furthermore, we developed a simple In Vitro 3D gingival model resembling the oral periodontal pocket to culture the biofilms of Staphylococcus aureus (S. aureus, Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans, and Porphyromonas gingivalis (P. gingivalis. The PDI efficacy of chitosan hydrogel was examined against periodontal biofilms cultured in this 3D gingival model. We found that the PDI effectiveness was limited due to leaving some of the innermost bacteria alive at the non-illuminated site. Using this 3D gingival model, we further optimized PDI procedures with various adjustments of light energy and irradiation sites. The PDI efficacy of the chitosan hydrogel against periodontal biofilms can significantly improve via four sides of irradiation. In conclusion, this study not only showed the clinical applicability of this chitosan hydrogel but also the importance of the light irradiation pattern in performing PDI for periodontal disease.

    The health benefits of exercise may be attenuated by sports and recreation related injury (SRI). Though the majority of SRI are mild and self-limiting, a significant number are serious and require orthopaedic intervention. The aims of this study were to assess the burden of these serious injuries on the orthopaedic inpatient service, and to investigate potential target areas for injury prevention. All 1,590 SRI seen in the ED over a 3-month period were analysed using the Patient Information Management System to determine which patients received inpatient orthopaedic care. The medical records of those 63 patients who required inpatient care under orthopaedics were reviewed and data collected on demographic features, history, operative procedure and theatre resources, and length of hospital stay. Data were analyzed using SPSS. SRI accounted for 12.3% of all ED presentations. The principal activities resulting in injury requiring orthopaedic care were soccer, hurling and informal play e.g. trampoline. Falls made up 37% of the overall mechanism of injury but 68% of the injuries severe enough to require operative management. Most operative procedures were performed as part of a routine day trauma list but 20% were performed out of hours. This group of injuries places a significant burden on a busy trauma service. Injury prevention measures such as public education regarding falls in sport may have a role in reducing this burden.

    Full Text Available Objective: to reveal the patterns of a change in heart rhythm and breathing in patients with acute systemic injury due to cold in hypothermic and early posthypothermic periods.Subjects and methods. Thirty patients aged 18 to 60 years (3 groups of 10 patients with mild, moderate, and severe cold injury were examined in hypothermic and posthypothermic periods. The patient groups did not differ in gender, age, and weight. Within the first 24 hours after admission, all the patients underwent high-resolution Holter electrocardiographic monitoring that recorded cardiac arrhythmias and breathing disorders.Results. During the therapy performed, as the degree of acute systemic cold injury increased, the patients were found to have a heart rate reduction (from 102 [90; 122] beats/min in Group 1 to 49 [38; 58] beats/min in Group 3 and a circadian index increase (from 105 [88; 125]% in Group 1 to 210 [185; 223]% in Group 3. With increased hypothermia, the victims were detected to have progressive cardiac rhythm and cardiac electrical conduction disturbances, such as supraventricular pacemaker migration, single and paired supraventricular premature beats, paroxysmal atrial tachycardia, atrial fibrillations, and ventricular premature beats. There was decreased heart rhythm variability in all the study groups, to the greatest extent in the patents with severe systemic cold injury. Late ventricular potentials were found in 2 and 7 patients with moderate and severe cold injury, respectively. Breathing disorders were recorded in all the study groups, the greatest increase in the frequency and duration of apnea/hypopnea episodes was noted in the patients with severe hypothermia. A fatal outcome occurred in 4 of the 10 patients with critical hypothermia due to the occurrence of idioventricular rhythm with transition to asystole.Conclusion. Systemic hypothermia is accompanied by cardiac rhythm and cardiac electrical conduction disturbances and respiratory depression

    Desquamative gingivitis (DG) is a clinical term used to describe red, painful, glazed, friable gingiva. It may be a manifestation of a mucocutaneous condition, such as lichen planus or other vesiculobulous disorders. Dentists must be aware of this rare clinical entity in order to distinguish DG from the far more common plaque-induced gingivitis. This case is unique in that it involves oral lichen planus and chronic DG, which may be secondary to plaque or a manifestation of the oral lichen planus. Intraoral examination and biopsy reports revealed features of chronic DG and oral reticular lichen planus.

    Periostin, a secreted adhesion molecule essential for periodontal tissue integrity, is highly expressed in the periodontal ligament and plays a critical role in tooth and bone development. The purpose of this study was to investigate periostin levels in the gingival crevicular fluid and serum of patients with periodontal disease and compare them with those of healthy individuals. Eighty individuals (41 males and 39 females; age range: 25-48 years) were enrolled in the study. Individuals were divided into three groups following clinical and radiographic examinations: the periodontal-healthy group (n = 20), gingivitis group (n = 30) and chronic periodontitis group (n = 30). Gingival crevicular fluid and serum samples were collected and periostin levels were determined using the enzyme-linked immunosorbent assay. The total amount and concentration of periostin decreased in gingival crevicular fluid with the progression and severity of the disease from healthy controls to gingivitis and to chronic periodontitis groups and differed significantly (p 0.05). Periostin in gingival crevicular fluid negatively correlated with the gingival index in the periodontal disease groups, whereas it is inversely correlated with the clinical attachment level only in the periodontitis group (p periodontal disease, and negatively correlated with the clinical parameters. Within the limits of the study, the periostin level in gingival crevicular fluid can be considered a reliable marker in the evaluation of periodontal disease susceptibility and activity. © 2014 John Wiley & Sons A/S.

    The effects of bodybuilding and protein supplements on periodontal tissues have not yet been evaluated. The present study aimed to examine the periodontal status and interleukin (IL)-1β, apoptosis-associated speck-like protein containing C-terminal caspase-recruitment domain (ASC), and caspase 1 (CASP1) gene expression levels of body builders compared with those of controls. Twenty-five bodybuilders with gingivitis (BB-G) who used protein powder supplements were compared with 25 nonexercising males with (G) and 25 without (H) gingivitis. Saliva, gingival crevicular fluid (GCF), and serum were collected for gene expression analysis. Plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP) were recorded. GI and BOP were higher in group BB-G and G than in group H (P 0.05). In GCF, CASP1, ASC, and IL-1β expression were upregulated in group G compared with groups BB-G and H (P Bodybuilding and supplement usage may decrease gingival inflammation by downregulating CASP1, IL-1β, and ASC.

    Reactive oxygen species might be associated with the onset and progression of gingival inflammation. The aim of this study is to investigate the effect of a dentifrice containing L-ascorbic acid 2-phosphate magnesium salt (APM), a long-acting ascorbic acid derivative with antioxidant properties, on gingival inflammation. The clinical effects of APM were investigated in a multicenter, randomized, parallel-group, controlled clinical trial comprising 300 individuals with gingivitis. Half of the participants were given an APM-containing dentifrice and half were given a control dentifrice. The primary outcome was the gingival index (GI) at 3 months. Secondary outcomes included gingival redness as an indicator of the degree of local gingival inflammation, gingival bleeding as a measure of the gingivitis severity index, and total antioxidant activity of the saliva. Under the intent-to-treat analysis, GI did not significantly differ between the groups (P = 0.12). However, under the per-protocol analysis, GI was significantly lower in the APM group (P = 0.01) than in the control group. In the APM group, gingival redness was significantly lower, and the difference from the baseline gingivitis severity index was significantly greater (P = 0.04 and P = 0.02, respectively). The total antioxidant activity of the saliva was significantly higher in the APM group (P = 0.03). The incidence of adverse events did not significantly differ between the groups (P > 0.15). These findings indicate that the regular application of an APM-containing dentifrice could reduce gingival inflammation.

    The aims of this study were to compare the detection of human herpesviruses (HHVs) in the saliva of HIV-infected and healthy control children, and to evaluate associations between viral infection and gingivitis and immunodeficiency. Saliva samples were collected from 48 HIV-infected and 48 healthy control children. Clinical and laboratory data were collected during dental visits and from medical records. A trained dentist determined gingival indices and extension of gingivitis. Saliva samples were tested for herpes simplex virus types 1 and 2 (HSV-1 and HSV-2), varicella zoster virus (VZV), Epstein-Barr virus (EBV), and cytomegalovirus (CMV) by nested polymerase chain reaction assays. Thirty-five HIV-infected and 16 control children had gingivitis. Seventeen (35.4%) HIV-infected children and 13 (27%) control children were positive for HHVs. CMV was the most commonly detected HHV in both groups (HIV-infected, 25%; control, 12.5%), followed by HSV-1 (6.2% in both groups) and HSV-2 (HIV-infected, 4.2%; control, 8.3%). The presence of HHVs in saliva was not associated with the presence of gingivitis in HIV-1-infected children (p = 0.104) or healthy control children (p = 0.251), or with immunosuppression in HIV-infected individuals (p = 0.447). Gingivitis was correlated with HIV infection (p = 0.0001). These results suggest that asymptomatic salivary detection of HHVs is common in HIV-infected and healthy children, and that it is not associated with gingivitis.

    42 periodontitis patients and 15 health controls are selected to determine the amount of tumor necrosis factor-α (TNF-α) in inflamed gingival and the normal gingival by RIA. The elations between TNF-α and clinical parameters are analysed. The results show that the level of TNF-α in inflamed gingival is higher than that in the controls (P<0.01). The relationship between TNF-α and clinical parameters indicate that the level of TNF-α positively correlate to the degree of periodontitis and group damage. It indicates TNF-α may be one of the mechanism in the pathogenesis of periodontitis disease

    Conclusion: Gingival overgrowth could be induced either by nifedipine or by tacrolimus, although the extent of gingival overgrowth induced by tacrolimus would be less than that by nifedipine. However, a concomitant administration of nifedipine and tacrolimus did not aggravate the induced gingival overgrowth.

    To evaluate the effectiveness of aloe vera containing herbal dentifrices in improving plaque control and gingival health. A manual and electronic literature (MEDLINE and Cochrane Central Register of Controlled Trials) search was performed up to July 2012, for randomized controlled trials presenting clinical, microbiological, immunological, and patient-centered data for the efficacy of aloe vera herbal dentifrices for controlling plaque and gingival inflammation in patients with gingivitis. From 79 titles and abstracts, eight full-text articles were screened and finally two randomized controlled trials were selected. These randomized controlled trials reported that aloe vera dentifrices were similar in efficacy to control dentifrices in effectively reducing plaque and gingival inflammation in gingivitis patients based on the assessment of clinical, microbiological, and patient-centered treatment outcomes. However, many important details (composition and characteristics of aloe vera and control dentifrices along with appropriate randomization, blinding, and outcomes assessed) were lacking in these trials, and therefore, the quality of reporting and methods was generally flawed with high risk of bias. Even though there are some promising results, the clinical effectiveness of aloe vera herbal dentifrices is not sufficiently defined at present and warrants further investigations based on reporting guidelines of herbal CONSORT statement. © 2013 John Wiley & Sons A/S.

    Full Text Available Periodontal disease is the major cause of adult tooth loss and is commonly characterized by a chronic inflammation caused by infection by oral bacteria. Members of Toll-like receptor (TLR family recognize conserved microbial structures, such as bacterial lipopolysaccharides, and activate signaling pathways that result in immune responses against microbial infections. The aim of the present study was to assess the mRNA expression of TLR-2 and TLR-4 in gingivitis and chronic periodontitis. Gingival tissue samples were collected from patients with chronic periodontitis, gingivitis, and healthy controls. Total RNA was extracted and RT-PCR was done for TLR-2 and TLR-4. The results showed that TLR-2 was significantly increased in gingivitis compared to TLR-4 expression and decreased in chronic periodontitis.

    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.

    Two patients with primary oculomotor nerve palsy due to direct mild head injury are reported. They presented with internal ophthalmoplegia, dilated nonreactive pupils, and very mild disturbance in consciousness. Except for the persistent oculomotor nerve palsy, both the patients recovered fully within one week. Neither demonstrated a history that was suggestive of a cause for their oculomotor nerve palsy. Initial CT scans demonstrated localized subarachnoid hemorrhage around the brain stem. One of the patients had sustained a fracture of the anterior clinoid process. As the underlying pathophysiologic mechanism underlying the oculomotor nerve palsy we suspected mild injury to the pupillomotor fibers at the anterior petroclinoidal ligament and that of the pupillary fibers at the posterior petroclinoidal ligament. We speculate that these perforating fibers at the anterior petroclinoidal ligament acted as a fulcrum due to downward displacement of the brainstem at the time of impact. (author)

    Gingival metastases are very rare. We report the case of a 47 year-old man presenting with a gingival metastasis from a non small cell lung carcinoma. According to the literature, the most probable way of spread of such metastasis is hematogenous. Local implantation of cancer cells, present in patient's expectoration, in a fragile gingival may be an other pathway of lung cancer metastasizing in this region as we will try to describe in this case report. Cytological and/or histological investigation is needed to assess the malignant and the metastatic character of these gingival lesions. A rapid regression is observed after a flash of external beam radiation; nevertheless metastasis prognosis depends on the primary tumour progress. (authors)

    This randomized controlled trial assessed the impact of Lactobacillus reuteri on pregnancy gingivitis in healthy women. Forty-five healthy women (24 test/21 placebo) with pregnancy gingivitis in the third trimester of pregnancy were enrolled. At baseline Gingival Index (GI) and Plaque Index (PlI) were assessed at the Ramfjord teeth and venous blood taken for TNF-α analysis. Subsequently participants were randomly provided with lozenges to be consumed 2 × daily until birth (approx. 7 weeks) containing ≥10 8 CFU L. reuteri ATCC PTA 5289 and ≥10 8 CFU L. reuteri DSM 17938 (test) or being devoid of L. reuteri (placebo). Within 2 days after birth recording of GI, PlI and blood sampling were repeated. At baseline, mean GI and mean PlI did not differ significantly between both groups.

    1988-01-01

    Light and electron microscopic studies and energy dispersive X-ray analysis disclosed that the essential cause of gingival discoloration following the placement of a metallic crown, was marked deposition of melanin pigment. Deposition of melanin pigment was observed in epithelial cells, on basement membranes, and in fibroblasts, macrophages and among intercellular ground substance of the proprial layer. Brown or dark brown colored granules were observed in the deep portion of the proprial layer. Some metallic elements as silver and sulfur were detected. It was presumed that these materials were dental metals accidentally implanted in gingival tissues during the therapeutic procedure. The deposition of melanin pigment closely corresponded with mucosal tissue where these materials were present in the deep portion of the proprial layer. These findings suggested that these materials influenced the physiological metabolism of melanin and induced its pathological deposition in the proprial tissue. (author)

    Pregnancy gingivitis and early childhood caries remain prevalent in Hong Kong. The aim of this study was to assess pregnant women's knowledge and beliefs related to pregnancy gingivitis and children's oral health. An outreach survey was carried out in a clinic that provided antenatal examination. A written oral health questionnaire related to pregnancy gingivitis and early childhood caries was administered to pregnant women. Of the 106 pregnant women who enrolled in the study, 100 completed the questionnaires. Among the 100 subjects, only 39% correctly identified that hormonal changes contribute to pregnancy gingivitis. Only 36% identified red and swollen gums as signs of gingivitis. Furthermore, 53% of the surveyed pregnant women were not sure about the amount of toothpaste to administer to a child aged 18 months to 5 years. Almost 50% assumed that a replanted avulsed tooth would probably not survive within a short extra-alveolar period of less than 60 minutes. Prenatal women generally lack knowledge of a common oral disease that occurs during pregnancy and of what constitutes adequate oral health care for children. Oral health care education should be implemented as part of a prenatal care program.

    Special Olympics athletes, as well as the general population of people with intellectual disabilities, are expected to have poorer gingival health. The aim of the study is to explore the prevalence of gingival signs of inflammation and its relationship to oral cleanliness and age among Special Olympics athletes from Europe and Eurasia. A retrospective longitudinal study was performed with data collected through standardized oral from 15.941 athletes from annual Special Olympics events held in 49 countries, from Europe and Eurasia between 2007 and 2012. The data was analysed descriptively, with One-Way ANOVA test and Chi-Square test. The level of significance was predetermined at a p value < 0.05. A total of 7,754 athletes presented with gingival signs (48.64%). There were no significant differences (p= 0,095) in mean gingival signs between age groups, however the association between mouth cleaning and age, was statistically significant. The data suggests that there is a high prevalence of gingival signs among individuals with special needs; over 50% in more than 20 countries. Therefore, there is a serious need for education and preventive programs for the patients, their parents and caregivers.

    Gingivitis is a common oral health problem. Untreated gingivitis may progress to periodontitis, a common cause of tooth loss. The prevalence of gingivitis and calculus among Puerto Rican children is unknown. Understanding this prevalence can support early public health preventative strategies. This study aims to estimate the prevalence of gingivitis and calculus among 12-year-old Puerto Ricans by health region and to explore differences in distribution by school type (proxy for socio-economic status) and gender. A probability-based sample of 113 schools was selected proportional to enrollment size and stratified by health region, school type, and gender. Two trained examiners evaluated the presence of gingivitis and both supragingival and subgingival dental calculus. Gingivitis was defined as the presence of gingival bleeding upon gentle probing (BOP) in at least one site, and the extent of the problem was classified according to the percentage of teeth whose gingiva presented BOP (limited: 25-49% of the teeth tested; extensive: >50% of teeth tested). Logistic and linear regression models, adjusted for health regions, were used to compare gingivitis and calculus prevalence and extent between genders and school types. Gingivitis was found in 80.41% of the 1586 children evaluated. Urban-public schoolchildren had a slightly higher prevalence (83.24%) compared to private (79.15%, p = 0.16); those in rural-public (77.59%) and private schools had similar prevalence (p = 0.15). Extensive gingivitis was present in 60.81% of all children. The mean percentage of sites presenting BOP (BOP%) was 17.79%. Rural and urban public schoolchildren presented significantly higher BOP% compared to children from private schools (p = 0.0005, p = 0.002, respectively). Dental calculus was detected in 61.59% of the sample, boys presenting significantly higher (p = 0.005) total and supragingival calculus. Rural-public schoolchildren had a significantly higher prevalence of

    A case is reported of a 20-year-old woman with generalized severe gingival overgrowth covering almost all of the teeth with diastemata, diagnosed as idiopathic gingival fibromatosis. After initial therapy, the patient underwent surgery consisting of a full-mouth internal beveled gingivectomy. Postoperatively, the maxillary anterior teeth spontaneously moved to almost optimal positions. Removing the cause by gingivectomy can lead to spontaneous correction of the pathologic tooth migration. With supportive periodontal treatment, the patient showed no recurrence of gingival enlargement or repositioning of the teeth at the 5-year follow-up.

    Full Text Available Cigarette smoke exposure compromises health through damaging multiple physiological systems, including disrupting metabolic function. The purpose of this study was to determine the role of oral gingiva in mediating the deleterious metabolic effects of cigarette smoke exposure on skeletal muscle metabolic function. Using an in vitro conditioned medium cell model, skeletal muscle cells were incubated with medium from gingival cells treated with normal medium or medium containing suspended cigarette smoke extract (CSE. Following incubation of muscle cells with gingival cell conditioned medium, muscle cell mitochondrial respiration and insulin signaling and action were determined as an indication of overall muscle metabolic health. Skeletal muscle cells incubated with conditioned medium of CSE-treated gingival cells had a profound reduction in mitochondrial respiration and respiratory control. Furthermore, skeletal muscle cells had a greatly reduced response in insulin-stimulated Akt phosphorylation and glycogen synthesis. Altogether, these results provide a novel perspective on the mechanism whereby cigarette smoke affects systemic metabolic function. In conclusion, we found that oral gingival cells treated with CSE create an altered milieu that is sufficient to both disrupted skeletal muscle cell mitochondrial function and insulin sensitivity.

    In the oral cavity, the epithelial surface is constantly exposed to a number of different microorganisms that are organized in a well-structured biofilm. The aim of this study was to monitor gingival expression of antimicrobial peptides (AMPs) and interleukin-8 (IL-8) in an early gingivitis model. Experimental gingivitis was allowed to develop in healthy volunteers (n = 17). Bleeding on probing (BOP%) and gingival crevicular fluid volume (GCF) were assessed at baseline and day 1, 3, 5, 7 and 14. Expression of AMPs (human beta-defensin-2, hBD-2; CC-chemokine ligand 20, CCL20; psoriasin, pso/S100A7) and IL-8 was analyzed by immunohistochemistry in gingival biopsies. In addition, hBD-2 and IL-8 protein expression was monitored in GCF using the ELISA technology. Experimental gingivitis gradually developed with an increase in BOP scores and GCF volume over time. In GCF, elevated concentrations of hBD-2 and IL-8 were monitored at day 1, 5 and 7 (p ≤ 0.0002). Immunohistochemical analysis of gingival sections demonstrated increased staining for hBD-2 at day 3, whereas the CCL20, pso/S100A7, and IL-8 expression was increased at later time points (p gingival inflammation. Differential temporal expression for AMPs may ensure a constant antimicrobial activity against changes in the bacterial composition of the growing dental biofilm. © 2015 John Wiley & Sons A/S.

  6. Strawberry gingivitis as the first presenting sign of wegener's granulomatosis: report of a case

    Science.gov (United States)

    2011-01-01

    Wegener's granulomatosis is a rare multi-system disease characterized by the classic triad of necrotizing granulomas affecting the upper and lower respiratory tracts, disseminated vasculitis and glomerulonephritis. Oral lesions as a presenting feature are only encountered in 2% of these cases. Hyperplastic gingival lesions or strawberry gingivitis, is a characteristic sign of Wegener's granulomatosis. The latter consists of reddish-purple exophytic gingival swellings with petechial haemorrhages thus resembling strawberries. Recognition of this feature is of utmost importance for timely diagnosis and definitive management of this potentially fatal disease. A case of strawberry gingivitis as the first presenting sign of Wegener's granulomatosis affecting a 50-year-old Malay male is reported here. The differential diagnosis of red lesions that may present in the gingiva is discussed. PMID:21813375

    Objective: To find the Frequency of Gingival and Periodontal Diseases among Troops Deployed in Operational Area and to evaluate the treatment needs which might be helpful in oral health policy planning and specific intervention against periodontal disease. Design: Descriptive study. Place and Duration of Study: The study was conducted at 140 mobile dental unit Swat from Dec 2009 to June 2011. Subjects and Methods: the periodontal status of 1500 personnels of Pakistan Army was examined using Basic periodontal Examination Index. Data was evaluated by SPSS version 16. Percentage of various gingival and periodontal disease traits was calculated and treatment needs determined. Results: Out of total 1500 subjects 12.8% subjects were having satisfactory periodontal health and required no treatment whereas 38.3% were having gingivitis requiring oral hygiene instruction and prophylaxis. Gingivitis modified by local factors was seen in 23.5% and required oral hygiene instruction and correction of modifying factors. Some (13.6%) were having mild periodontitis and required scaling, root planning and oral hygiene instruction whereas 11.8% were having moderate or advance periodontitis and required comprehensive periodontal treatment including surgical treatment. Conclusion: A large number of cases (82.7%) of gingivitis and periodontitis were detected in subject population which shows lack of awareness and self -consciousness among troops regarding their oral hygiene.

    1990-06-01

    Gingival biopsy specimens from eight patients exhibiting a localized, erythematous, or mixed erythematous/leukoplakic gingivitis that was refractory to conventional periodontal therapy were examined histologically and by energy-dispersive X-ray microanalysis. Histologic examination revealed variable numbers of small, usually subtle, sometimes equivocal, and occasionally obvious foci of granulomatous inflammation. Special stains for fungi and acid-fast bacilli were consistently negative. In all cases, the granulomatous foci contained particles of foreign material that were often inconspicuous and easily overlooked during routine histologic examination. Energy-dispersive X-ray microanalysis of these foreign particles disclosed Ca, Al, Si, Ti, and P in most lesions. However, other elements such as Zr, V, Ag, and Ni were found only in specific biopsy specimens. By comparing the elemental analyses, clinical features, and history of the lesions, strong evidence for an iatrogenic source of the foreign material was found in one case, and good evidence in five cases. In the remaining two patients, the source of the foreign particles remains unresolved.

    Full Text Available For solving the problem of diagnosis and treatment of hard tissue defects the significant role belongs to the choice of tactics for dental treatment of hard tissue defects located in the gingival line of any tooth. This work aims to study the problems of diagnosis and classification of gingival line defects of the teeth hard tissues. That will contribute to the objectification of differentiated diagnostic and therapeutic approaches in the dental treatment of various clinical variants of these defects localization. The objective of the study – is to develop the anatomical-functional classification for differentiated estimation of hard tissue defects in the gingival part, as the basis for the application of differential diagnostic-therapeutic approaches to the dental treatment of hard tissue defects disposed in the gingival part of any tooth. Materials and methods of investigation: There was conducted the examination of 48 patients with hard tissue defects located in the gingival part of any tooth. To assess the magnitude of gingival line destruction the periodontal probe and X-ray examination were used. Results. The result of the performed research the classification of the gingival line defects of the hard tissues was offered using exponent power. The value of this indicator is equal to an integer number expressed in millimeters of distance from the epithelial attachment to the cavity’s bottom of defect. Conclusions. The proposed classification fills an obvious gap in academic representations about hard tissue defects located in the gingival part of any tooth. Also it offers the prospects of consensus on differentiated diagnostic-therapeutic approaches in different clinical variants of location.  This classification builds methodological “bridge of continuity” between therapeutic and prosthetic dentistry in the field of treatment of the gingival line defects of dental hard tissues.

Algunas personas al sonreír muestran la encía por encima de la base de los dientes, lo que ocasiona un aspecto antiestético. Esta situación repercute negativamente en el individuo, ya que altera la espontaneidad de la expresión facial. En el origen de la sonrisa gingival intervienen factores dentales, esqueléticos y de tejidos blandos. Proponemos una variante quirúrgica innovadora para corregir la sonrisa gingival en pacientes con alteraciones de los tejidos blandos. Se intervinieron quirúrgicamente 15 mujeres de entre 17 y 38 años de edad. En 7 de ellas se practicó rinoplastia además de corrección de la sonrisa gingival. Las 8 restantes se sometieron exclusivamente a corrección de la sonrisa gingival. Las 15 pacientes intervenidas mejoraron su apariencia y autoestima. No hubo complicaciones o problemas relacionados con la herida quirúrgica. Los resultados han sido permanentes a medio y largo plazo. La sonrisa de las pacientes es normal, mejoró su expresión y se conservaron la sensibilidad y la función muscular. La técnica propuesta es sencilla y de fácil reproducción; el tiempo quirúrgico estimado es de una hora y la operación es de tipo ambulatoria. Suele ser bien tolerada por los pacientes y no altera sus actividades cotidianas.

    Full Text Available Background: In the current practice of periodontics, clinicians are faced with the challenge of not only addressing biological and functional problems present in the periodontium but also providing therapy that results in acceptable aesthetics. The presence of mucogingival problems and gingival recession around anterior, highly visible teeth exemplifies a situation in which a treatment modality that addresses both biological and aesthetic demands is required from the therapist. A variety of soft tissue augmentation procedures directed at root coverage have been documented in the literature utilizing autogenous or allogenic soft tissue grafting or guided tissue regeneration (GTR. The purpose of this review was to assess the effectiveness of newer materials in gingival augmentation procedures.

    Also note that structured abstracts are not allowed per journal style: What is the effect of a mouthwash containing various active chemical ingredients on plaque control and managing gingivitis in adults based on evidence gathered from existing systematic reviews? The summarized evidence suggests that mouthwashes containing chlorhexidine(CHX) and essential oils (EO) had a large effect supported by a strong body of evidence. Also there was strong evidence for a moderate effect of cetylpyridinium chloride(CPC). Evidence suggests that a CHX mouthwash is the first choice, the most reliable alternative is EO. No difference between CHX and EO with respect to gingivitis was observed. Copyright © 2015 Elsevier Inc. All rights reserved.

    Antithrombotic drugs are known to increase the risk of gingival bleeding because they affect coagulation. However, other drugs could also be involved in gingival bleeding. We performed a pharmacoepidemiological study to identify the drugs most frequently "suspected" in the occurrence of gingival bleeding. We selected reports of "gingival bleeding" from 1 January 1985 to 30 September 2014 in the French PharmacoVigilance Database. Among 523,808 reports of adverse drug reactions, we identified 454 reports of gingival bleeding (0.09%). Most of them were "serious" (58.4%) and occurred in females (54.6%). The frequency of gingival bleeding increased with age. The most frequently "suspected" drugs were antithrombotics (67.8%), particularly fluindione. Other drugs frequently involved were furosemide followed by paracetamol, amiodarone, amoxicillin, paroxetine, ketoprofen, zolpidem, enalapril and ramipril. Thirty-nine reports involved a drug-drug interaction with antithrombotics, mainly with anti-infectives. Gingival bleeding can be an adverse drug reaction, often "serious" and rarely fatal. Patients older than 50 years and women are particularly at risk. Among drugs known to increase the risk of gingival bleeding, the most frequently involved were fluindione, furosemide, paracetamol, amiodarone, amoxicillin, paroxetine or ketoprofen. We also identified signal for drugs not usually known to be involved in bleeding, like zolpidem, enalapril or ramipril. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Gingival recession is a condition that affects a large portion of the young and adult population and negatively affects the aesthetic aspects of the smile. Many factors are related to its development, including orthodontic movement beyond the osseous limits. Many treatment options have been proposed to cover the exposed root surface. The aim of this article was to describe three cases where a subepithelial connective tissue graft was performed, using a microsurgical technique, in the treatment of deep gingival recession after orthodontic treatment. This technique resulted in successful root coverage and keratinized tissue gain, improving the gingival esthetic pattern.

    Calcifying nanoparticles (CNPs), also known as nanobacteria, can produce carbonate apatite on their cell walls and initiate pathologic calcification. The objective of this study was to determine whether CNPs are present in the gingival crevicular fluid (GCF) from subjects with periodontal disease and whether they can induce the pathologic calcification of primary cultured human gingival epithelial cells. GCF and dental calculus samples were collected from 10 subjects with gingivitis and 10 subjects with chronic periodontitis. CNPs in GCF and calculus filtrates were detected with nanocapture enzyme-linked immunosorbent assay kits. The CNPs in cultures of dental calculus filtrates were also identified using immunofluorescence staining, transmission electron microscopy (TEM), and chemical analysis. Pathologic changes in the CNP-treated gingival epithelial cells were observed with TEM, alizarin red staining, and disk-scanning confocal microscopy. CNPs were found in GCF samples from two subjects with chronic periodontitis. Based on chemical analysis, the surface-associated material from CNPs isolated and cultured from calculus has a composition similar to dental calculus. The pathologic calcification of CNP-treated gingival epithelial cells was also observed. Self-replicating calcifying nanoparticles can be cultured and identified from dental calculus. This raises the issue of whether CNPs contribute to the pathogenesis of periodontitis.

    Full Text Available INTRODUCTION: The term Gingival cleft refers to a fissure in the gingival tissues and is usually caused by traumatic oral hygiene, abnormal frenula, trauma from occlusion, orthodontic, or pierce related trauma. Gingival clefts are classified depending on the extent of the inclusion of the gingival thickness into red and white. The recommended treatment approach for the incomplete white clefts is the gingivectomy of the affected keratinized tissue followed by a coronally advanced flap for the root coveradge, while the complete white clefts are treated with a laterally moved, coronally advanced flap, or a free gingival graft procedure. OBJECTIVE: This report presents a case with a spontaneous healing of an incomplete gingival cleft associated with a maxillary labial frenulum after an alternative frenuloectomy approach. METHODS: M.G. (45 with a localized chronic periodontitis, an abnormal papillary maxillary frenulum and an incomplete white cleft on the marginal gingiva of the left central incisor. An alternative frenuloectomy approach combined with a free gingival graft was selected for the correction of the abnormal frenulum. RESULTS:On the sixth month after the surgical procedure an almost complete recovery of the gingival margin was observed.The result at the third year demonstrates a stable gingival margin with a complete tissue recovery. CONCLUSION: The applied combined surgical approach led to a complete gingival recovery of the incomplete white gingival cleft without the commonly used gingivectomy and CAF. Further research is recommended to clarify the adjunctive benefits of the FGG in patients with gingival clefts associated with abnormal frenula.

    The aim of this randomized, double-blinded, placebo-controlled study was to evaluate if downregulation of the inflammatory response due to ingestion of high levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) can slow down gingivitis development, and thus delay the progression of periodontal disease (PD) in dogs. To this aim, 44 client-owned adult dogs (>1 and  0.63) and C reactive protein (p = 0.28) then the ones consuming corn oil. There were no differences between fish oil and corn oil diet supplementation on plaque (18.2 vs. 17.8, p = 0.78), calculus (10.1 vs. 11.5, p = 0.18) or gingivitis (19.3 vs. 19.0, p = 0.77) indexes. The authors conclude that supplementation with EPA + DHA does not slow down progression of PD in dogs. © 2018 Blackwell Verlag GmbH.

    Full Text Available Objectives: The gingival and periodontal changes during pregnancy are well known. Gingivitis is the most prevalent oral manifestations associated with pregnancy. The hormonal and vascular changes that accompany pregnancy are known to exaggerate the inflammatory response to the local irritants. Hence, a study was designed to assess oral hygiene status, gingival status, periodontal status, and treatment needs (TNs among pregnant and nonpregnant women. Materials and Methods: A cross-sectional study was conducted among 120 pregnant and 120 nonpregnant women of 18–44 years age attending the Outpatient Department of Gynaecology and Obstetrics in Government Hospital of Belgaum city, Karnataka, India. The study consisted of an interview and oral examination. Type 3 examination was followed. Simplified Oral Hygiene Index (OHI-S, Gingival Index, and Community Periodontal Index and TNs Index were used to assess “oral hygiene status,” “gingival status,” and “periodontal status and TNs,” respectively. Results: The pregnant women showed poor oral hygiene with the mean OHI-S score as 2.68. Gingivitis was prevalent in almost all the pregnant and nonpregnant women. However, it was found more severe in pregnant women with mean gingival score as 1.25. A definite increase in gingivitis was found from Trimester II to Trimester III. The mean number of sextants showing healthy gingiva was significantly (P < 0.01 lower among pregnant women. Conclusions: Pregnant women showed poor oral hygiene, more gingival inflammation, and more periodontal disease as compared to nonpregnant women. The severity of gingivitis increased in Trimester III. Proper oral hygiene practice can prevent these diseases and further complications.

    Interdental soft tissues play a critical role in pink esthetics. The presence and preservation of the interdental papillae in the esthetic zone is as crucial as the shape and contour of the anterior teeth in achieving an esthetically pleasing smile. The present study determines the association of central papilla recession with gingival and interdental smile line in periodontally healthy patients of different age groups. The present study included 200 patients equally divided into 21 to 40 years and 41 to 60 years age groups. The clinical and photographic evaluation of the central papilla, with midfacial gingiva, and its relationship with the vermilion border was performed. In total, 137 patients exhibited presence of central papilla, whilst 63 patients had central papilla recession with variable extent. The male patients predominantly had presence of central papilla in both the age groups, with 86% and 64%, compared with 74% and 50% in females, respectively. High gingival smile line was seen in the majority of the patients (62%), and this trend was similar to high interdental smile line (82% of the patients). Esthetics is affected in individuals having papilla recession along with high gingival smile line and interdental smile line as compared to individuals with low or cupid bow gingival smile line and interdental smile line.

    To estimate the years of potential life lost, years of potential productive life lost and the labor productivity losses attributable to premature deaths due to traffic injuries between 2002 and 2012 in Spain. Several statistical sources were combined (Spanish Registry of Deaths, Labor Force Survey and Wage Structure Survey) to develop a simulation model based on the human capital approach. This model allowed us to estimate the loss of labor productivity caused by premature deaths following traffic injuries from 2002 to 2012. In addition, mortality tables with life expectancy estimates were used to compute years of potential life lost and years of potential productive life lost. The estimated loss of labour productivity caused by fatal traffic injuries between 2002 and 2012 in Spain amounted to 9,521 million euros (baseline year 2012). The aggregate number of years of potential life lost in the period amounted to 1,433,103, whereas the years of potential productive life lost amounted to 875,729. Throughout the period analyzed, labor productivity losses and years of life lost diminished substantially. Labor productivity losses due to fatal traffic injuries decreased throughout the period analyzed. Nevertheless, the cumulative loss was alarmingly high. Estimation of the economic impact of health problems can complement conventional indicators of distinct dimensions and be used to support public policy making. Copyright © 2014 SESPAS.

    Full Text Available Aim. Periodontal remodellng produced during dental orthodontic treatment represents a series of biologicallyactive substances, part of them playing some role in the initiation and propagation of inflammatory processes. The present study aims at demonstrating the MMP8, MMP9 and TIMP1 levels intervening in tissular periodontal remodeling produced during orthodontic treatments, accompanied by gingival overgrowth, as a reaction of the marginal periodontium to mechanical stress. Materials and Method. Selected for the study were 21 patients – 13 females and 8 males – with ages between 13 and 32 years (17.6±1.3 years affected with dento-maxillary anomalies, who received orthodontic treatment with fixed apparatus. Sampling from the gingival fluid was performed 6 times, namely: 1 hour prior to the application of the orthodontic apparatus, 4 hours after its application, again after 8 and 24 hours and then 1 and, respectively, 2 weeks later. If gingival hypertrophy was installed (HTG, the hypertrophic gingiva was removed, and an immuno-histo-chemical examination was made. The patient was weekly monitorized in the first 6 weeks – during the initial orthodontic treatment, then monthly, samples being taken over from the gingival sulcus on each visit made in the first 6 weeks. Results. MMP-9 immuno-marking was positive both at corione level and in the deep structures of the covering epithelium. The positive cells at MMP-9 evidenced different intensities at the level of each structure forming the gingival mucous membrane. In four of the cases under analysis, disorganization of the normal layering/stratification of the epithelium was evidenced, along with the presence of numerous red cells in the chorione of the mucous membrane. In such cases, immuno-marking to MMP8 showed a normal intensity, even if few positive cells, dispersed among the extravasated red cells could be observed. Immunologically, MMP8 and MMP9 obey the same pattern, registering maximum

    Necrotizing ulcerative gingivitis is the most common clinical syndrome preceding noma. It is found in developing countries and in malnourished children and especially in deprived groups such as children at Koranic boarding schools. The objective of this study was to determine the prevalence of necrotizing ulcerative gingivitis and factors associated with its occurrence in a boarding school population. This was a cross-sectional study of children in Koranic boarding schools in the city of Touba, Senegal. A multistage sampling strategy was used and 8 out of 17 schools were selected. The variables collected were gender, age, oral hygiene habits, duration of residence, presence of ulcerative gingivitis and plaque, and gingival bleeding index. A logistic regression analysis with R software using the manual procedure down was used to identify factors associated with the dependent variables. There were 501 participants and boys made up 92% of the study group. The mean age was 9.3 (sd 4.0) years. The mean of duration residence was 3.4 (sd 1.5) years. The prevalence of necrotizing ulcerative gingivitis was 37% and 81% of children did not use a toothbrush or a chewing-stick. The length of residence, school size, hygiene habits and plaque and bleeding indices were significantly associated with necrotizing gingivitis after adjustment for other variables. It is necessary to develop oral hygiene programs, to establish policies to manage the oral health of children and to improve health and nutrition at Koranic boarding-schools.

    Lactobacillus spp. and bifidobacteria are the most frequently used probiotics in oral health research. However, although probiotic effects have been suggested for other genera, such as bacilli, no trials are available to describe the effect of bacilli probiotics on gingivitis in humans. The aim of the present study was to evaluate the clinical effects of a bacilli-containing toothpaste, a mouthrinse and a toothbrush cleaner versus a placebo in patients with generalized gingivitis. In this double-blind placebo-controlled randomized clinical trial, nonsmoking, systemically healthy patients with generalized gingivitis were included. They used a placebo or an experimental probiotic Bacillus subtilis-, Bacillus megaterium- and Bacillus pumulus-containing toothpaste, mouthrinse and toothbrush cleaner for 8 wk. Primary outcome measures of interest were plaque and gingivitis index, and the secondary outcome measures were pocket probing depth and bleeding on probing. Twenty male and 20 female patients were randomized over the two groups. All participants could be included in the final analysis. Although plaque and gingivitis indices were significantly reduced after 8 wk, no intergroup differences could be found at any time point. Also, for the secondary outcome measure, intragroup but no intergroup differences could be detected. No harm or unintended effects were reported by the patients after using the study products. This study did not show any statistically significant differences between a placebo and a bacilli-containing toothpaste, mouthrinse and toothbrush cleaner on gingivitis parameters. © 2016 John Wiley & Sons A/S.

    Full Text Available Gingival fibromatosis is characterized by gingival tissue overgrowth of a firm and fibrotic nature. The growth is slow and progressive and is drug-induced, idiopathic, or hereditary in etiology. It occurs isolated or frequently as a component of various syndromes. Our patient presented with the complaint of gingival enlargement associated with progressive deafness, characteristic of Jones syndrome. This case report is important and unique since it is the first known one to have a Jones syndrome-like presentation without a family history. A male patient aged 14 years reported with the chief complaint of swelling of gums and progressive hearing loss in both ears for the past one year. There was no family history or history of drug intake. Enlargement was generalized, fibrotic and bulbous, involving the free and attached gingiva, extending up to the middle 1/3 rd of the crown. Investigations such as pure tone audiogram, impedance audiometry, and Tone decay test concluded that there was severe right and moderate left sensorineural hearing loss. The case was diagnosed to be idiopathic, generalized gingival fibromatosis with progressive hearing loss. The gingival overgrowth was managed by gingivectomy and periodic review. The patient was advised to use high occlusion computer generated hearing aids for his deafness as it was not treatable by medicines or surgery. This unique case report once again emphasizes the heterogeneity of gingival fibromatosis, which can present in an atypical manner.

    This double-blind parallel-design clinical study compared the efficacy of a stabilized stannous fluoride dentifrice (Crest Plus Gum Care), baking soda and peroxide (NaF) dentifrice (Mentadent), and essential oil mouthrinse (Listerine) to a conventional NaF dentifrice (Crest) for the control of plaque, gingivitis and gingival bleeding over six months. Following an initial baseline examination and stratification, subjects received a complete oral prophylaxis and were distributed assigned test products. Following three and six months, subjects re-visited the clinic for examinations. Evaluations at baseline and at 3 and 6 months included soft tissue status. Löe-Silness gingivitis/gingival bleeding, Silness-Löe plaque and dental stain. Results subsequent to six months of product use were as follows: At six months, the stabilized stannous fluoride dentifrice was observed to produce statistically significant 17.5% reductions in gingivitis and 27.5% reductions in gingival bleeding relative to the NaF dentifrice. The combination of sodium fluoride dentifrice and essential oil mouthrinse produced statistically significant reductions of 7.4% in gingivitis and 10.8% in plaque as compared with the NaF dentifrice. The stabilized stannous fluoride dentifrice produced statistically significant reductions in both gingivitis (10.8%) and gingival bleeding (23.0%) relative to the combination of sodium fluoride dentifrice and essential oil mouthrinse. The baking soda and peroxide (NaF) dentifrice did not provide reductions in gingivitis, plaque or gingival bleeding as compared with the conventional NaF dentifrice. The stabilized stannous fluoride dentifrice provided statistically significant reductions in gingivitis as compared with the baking soda and peroxide dentifrice following six months of use, and both the essential oil mouthrinse and stabilized stannous fluoride dentifrice provided statistically significant reductions in gingivitis as compared with the baking soda and

    Porphyromonas gingivalis is considered as a major etiological agent in periodontal diseases and implied to result in gingival inflammation under orthodontic appliance. rag locus is a pathogenicity island found in Porphyromonas gingivalis. Four rag locus variants are different in pathogenicity of Porphyromonas gingivalis. Moreover, there are different racial and geographic differences in distribution of rag locus genotypes. In this study, we assessed the prevalence of Porphyromonas gingivalis and rag locus genotypes in 102 gingival crevicular fluid samples from 57 cases of gingivitis patients with orthodontic appliances, 25 cases of periodontitis patients and 20 cases of periodontally healthy people through a 16S rRNA-based PCR and a multiplex PCR. The correlations between Porphyromona.gingivalis/rag locus and clinical indices were analyzed. The prevalence of Porphyromonas gingivalis and rag locus genes in periodontitis group was the highest among three groups and higher in orthodontic gingivitis than healthy people (porthodontic gingivitis and mild-to-moderate periodontitis in Shandong. Porphyromonas.gingivalis carrying rag-1 has the strong virulence and could be associated with severe periodontitis. PMID:23593379

    What is the effect of mechanical inter-dental plaque removal in addition to toothbrushing, on managing gingivitis using various formats of inter-dental self-care in adults based on evidence gathered from existing systematic reviews? Three Internet sources were searched by a strategy designed to include systematic reviews on inter-dental cleaning devices. Plaque and gingivitis scores were the primary parameters of interest. Characteristics of selected papers were extracted. The potential risk of bias was estimated and the acquired evidence was graded. Screening of 395 papers resulted in six systematic reviews. Two papers evaluated the efficacy of dental floss, two of inter-dental brushes (IDB), one of woodsticks and one of the oral irrigator. Weak evidence of unclear or small magnitude was retrieved that supported dental floss, woodsticks and the oral irrigator to reduce gingivitis in addition to toothbrushing. No concomitant evidence for an effect on plaque emerged. There is moderate evidence that IDBs in combination with toothbrushing reduce both plaque and gingivitis. Evidence suggests that inter-dental cleaning with IDBs is the most effective method for inter-dental plaque removal. The majority of available studies fail to demonstrate that flossing is generally effective in plaque removal. All investigated devices for inter-dental self-care seem to support the management of gingivitis, however, to a varying extend. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Histone deacetylase inhibitors (HDACi) are being considered to treat chronic inflammatory diseases at low doses. Currently HDACi that are more specific are being developed to target particular HDACs; therefore, this study aimed to determine levels and distribution of class I and II HDAC in human gingival samples obtained from patients with chronic periodontitis. Gingival biopsies were obtained from patients with and without (mild inflammation, no bone loss) periodontitis. Total RNA was isolated for real-time quantitative polymerase chain reaction to determine expression of HDACs 1-10. Immunohistochemistry was used to determine protein distribution of HDACs 1, 5, 8 and 9. Factor VIII, CD3 and tartrate resistant acid phosphatase (TRAP) were detected in serial sections to identify blood vessels, lymphocytes, pre-osteoclasts and osteoclasts cells respectively. Tumour necrosis factor α (TNF-α) expression was also assessed. mRNA for HDAC 1, 5, 8 and 9 were significantly upregulated in chronic periodontitis gingival tissues compared to non-periodontitis samples (p chronic periodontitis samples (p chronic periodontitis gingival tissues. HDAC 1, 5, 8 and 9 expression was higher in gingival tissues from patients with chronic periodontitis compared to non-periodontitis samples. Results suggest that these HDACs could therefore be targeted with specific acting HDACi. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

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

  17. Gingival immunologic defense index: a new indicator for evaluating dental plaque infection risk in allergic children

    Full Text Available There is a possible relationship between dental plaque and children allergic diseases. According to literatures, gingivitis suffered mostly by allergic children than control. Case reports also revealed that dental plaque control therapy was able to reduce, even eliminate rhinosinusitis and asthmatic symptoms without additional medications. However, the exact method for confirming the gingivitis-related allergy is still uncertain. Allergic diseases have multifactorial etiologies and dental plaque had been proposed as a new trigger of allergic symptoms. Nevertheless, since not every child with gingivitis suffered from allergy or vice versa, this uncertain phenomenon may lead to patients or other clinician disbelief. The objective of the present study was to propose a new method, which involving the Gingival immunologic defense index (GIDI to evaluate the susceptibility to allergic diseases. GIDI is an index that had been developed earlier for evaluating gingival immunologic defense with respect to immunoglobulin A (IgA levels. This index based on the simple count of the inflamed gingival surfaces of a child plus the measurement of salivary IgA content. It provides clinicians with important information about the immunologic defense potential of each subject. Interestingly, most allergic children also had inherited IgA deficiency, thus this concept is likely. Based on literatures, GIDI could be a potential index for evaluating the risk of allergic diseases through gingival health assessment. However, prior investigation to the value of Indonesian GIDI index which related to allergy should be conducted.

    School-age children are frequently at high risk for the onset of biofilm-dependent conditions, including dental caries and periodontal diseases. The objective of this study was to evaluate the clinical efficacy of a dentifrice containing Eugenia uniflora Linn. (Surinam cherry) extract versus a triclosan-based comparator in treating gingivitis in children aged 10-12 years. The in vitro antibacterial potential of the dentifrice was tested against oral pathogens (Streptococcus mutans, Streptococcus oralis and Lactobacillus casei). Then a phase-II clinical trial was conducted with 50 subjects aged 10-12 years, with clinical signs of gingivitis. The subjects were randomly assigned to the experimental group (n=25) and control group (n=25), in which participants used the experimental dentifrice and a triclosan-based fluoridated dentifrice (Colgate Total 12(r)), respectively. Clinical examinations assessed the presence of gingivitis (primary outcome) and biofilm accumulation (secondary outcome) using the Gingival-Bleeding Index (GBI) and Simplified Oral Hygiene Index (OHI-S), respectively, at baseline and after seven days of tooth brushing 3x/day. The data were analyzed using paired and unpaired t-test (GBI) and Wilcoxon and Mann-Whitney (OHI-S), with p≤0.05. The experimental dentifrice showed efficient antibacterial activity in vitro. In the clinical trial, a significant reduction in gingival bleeding was observed in both experimental and control groups (puniflora dentifrice showed anti-gingivitis properties in children aged 10-12 years. Thus, it may be a potentially efficient and safe product to be used alternatively in preventive dental practice.

    1986-01-01

    For the purpose of studying radiation injury on mandibles at growth stage, the mandibles of young adult dogs were irradiated with X-ray of 200 kVp, and the irradiated intraoral tissues such as gingival membrane, teeth and mandibles were investigated macroscopically and the teeth and mandibles radiologically. The results were as follows: 1. As the injury on irradiated skin, partial epilation began two days after irradiation and ulceration (4 out of 16 cases) formed at 79 days and worsened further, and necrosis was seen in all subjects at 195 days. 2. As the injury on the intraoral tissue, pigment loss in the gingival membrane began four days after irradiation. Ulceration of gingiva (2 out of 16) formed at 30 days and worsened, and exposure of the alveolar bone was observed at 208 days. At 220 days, bone fracture (6 out of 16) was observed. 3. Formation of necrosis in the gingiva leading to necrosis of the skin corresponding to the third premolar was found in four cases. Formation of necrosis in the skin corresponding to the third premolar leading to necrosis of the gingival membrane was found in 12 cases. 4. In radiological findings, enlargement of periodontal membrane space, disappearance of lamina dura (6 out of 16), and resporption of the alveolar crest (6 out of 16) began in the subjects at 1 month. Worsening began with bone destruction (10 out of 16), bone destruction accompanied by osteosclerosis, and erosion of inferior border of the cortical bone (8 out of 16) in the subjects at 3 months. Formation of sequestrum (4 out of 16) at 6 months and bone fracture (6 out of 16) at 8 months were observed. 5. In radiological findings for the subjects with formation of ulceration, enlargement of periodontal membrane space, and resorption of the alveolar crest were the early findings and lamina dura image around the bone destruction image followed.

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

    The purpose of this study was to compare the cytotoxicity of four denture adhesives on human gingival fibroblast cells. Immortalized human gingival fibroblasts were cultured with one of four different denture adhesives, Polident, Protefix, Staydent or Denfix-A, which was placed in insert dishes (10% w/v concentration) for 48 h. The MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay and flow cytometric apoptosis assay were used to evaluate cell viability and apoptosis rates. The fibroblasts were also examined under a scanning electron microscope. The MTT assay showed that all denture adhesives resulted in a significantly lower cell viability compared to the control cells propagated in normal culture medium (p 0.05). Staydent showed the highest apoptosis rate. Scanning electron microscopy showed that the cells of the Staydent group underwent cytoplasmic membrane shrinkage, with cell free areas containing residual fragments of the membrane of dead cells. The four denture adhesives evaluated in this study imparted cytotoxic effects on human gingival fibroblast cells. Staydent showed the highest toxicity.

    Gingivitis in traditional national dentistry referred to independent diseases or symptomatic condition in periodontitis and classified morphologically. The diagnostic features of the diseases are characteristic, but the clinical presentation of symptomatic gingivitis and patterns of bone destructions may vary between patients. Successful treatment of the disease depends from proper diagnosis and advanced disease stages, but for symptomatic gingivitis that accompanying chronic periodontitis, protocols include surgical excision. Despite of the high prevalence of chronic generalized periodontitis, its active treatment often start in severe destruction and bone loss (2-3 stage severity). Today etiotropic antimicrobial therapy is real way to control microbial biofilm and has solid evidence base. Applying of etiotropic antimicrobial therapy as systemic azithromycin with timely treatment of mild to moderate periodontal and bone destruction may reduce severe periodontitis incidence of and treatment-related complications in the future. This paper attempts to describe the clinical diagnostic features and the current treatment options along with a suggested protocol for comprehensive management of chronic generalized periodontitis and hypertrophic gingivitis patient with case reports and a brief review.

    The rehabilitation of edentulous maxillae is a complex procedure due to the involvement of esthetic and functional requirements. A trial maxillary denture can be used to identify the need for adequate upper lip support when replacing removable complete dentures by implant-fixed dental prostheses. This clinical report describes the outcome of the rehabilitation of an edentulous atrophic maxilla with unfavorable maxillomandibular relationship and deficient upper lip support. A trial denture was fabricated and used to diagnose the need for a prosthesis capable of restoring the upper lip support. The reduced upper lip support was also confirmed by a lateral cephalogram. The patient was rehabilitated by an implant-fixed dental prosthesis associated with an attachment-retained gingival prosthesis. The case presented shows that when loss of upper lip support is detected and the patient does not wish to undergo further surgical reconstruction procedure, the retention of a gingival prosthesis using a ball attachment is a satisfactory treatment option. © 2014 by the American College of Prosthodontists.

    Full Text Available Abstract   Background & aim: Entamoeba gingivalis and Trichomonas tenax are oral protozoa that could cause periodontitis and gingivitis. The present study was done to determine the prevalence of these two protozoa in people over 14 years with periodontitis and gingivitis.   Methods: In this descriptive, cross-sectional study, 540 patients referring Resalat Dental Clinic, Shahrekord were enrolled and assigned in two groups of 270 patients with periodontitis and gingivitis and270 healthy individuals. The prepared specimens were examined by extensive wet procedures, Gimsa staining and Trichorom staining. Data were analyzed by chi-square, Fisher’s exact test, and logistic regression in SPSSv.20.   Results: No E. gingivalis- and T. tenax-positive cases were seen in the healthy group. The prevalence of E. gingivalis and T. tenax was obtained 3% by extensive wet procedure, 1.9% by Trichoderma staining, and 0.7% by Giemsa staining respectively. By logistic regression model, none of variables of age, gender, place of residence, smoking, tooth brushing, flossing, and oral PH were associated protozoan infection of E. gingivalis and T. tenax (P>0.05. Conclusion: In patients with periodontitis and gingivitis referred to the dental clinic, parasitic infections were attenuated to gingivialis and trichomoniasis vaginalis, and possibly other non-parasitic agents, including bacteria or other microorganisms, may play a role.

    Full Text Available Gingival crevicular fluid (GCF can be found in the physiologic space (gingival sulcus, as well as in the pathological space (gingival pocket or periodontal pocket between the gums and teeth. In the first case it is a transudate, in the second an exudate. The constituents of GCF originate from serum, gingival tissues, and from both bacterial and host response cells present in the aforementioned spaces and the surrounding tissues. The collection and analysis of GCF are the noninvasive methods for the evaluation of host response in periodontal disease. These analyses mainly focus on inflammatory markers, such as prostaglandin E2, neutrophil elastase and β-glucuronidase, and on the marker of cellular necrosis - aspartat aminotransferase. Further, the analysis of inflammatory markers in the GCF may assist in defining how certain systemic diseases (e.g., diabetes mellitus can modify periodontal disease, and how peridontal disease can influence certain systemic disorders (atherosclerosis, preterm delivery, diabetes mellitus and some chronic respiratory diseases. Major factors which influence the results obtained from the analyses of GCF are not only the methods of these analyses, but the method of GCF collection as well. As saliva collection is less technique-sensitive than GCF collection, some constituents of saliva which originate from the GCF can be analyzed as more amenable to chairside utilization.

    The aim of this study was to determine the prevalence of Entamoeba gingivalis and Trichomonas tenax in periodontitis and gingivitis patients. The study consisted of 107 periodontitis patients and 68 gingivitis patients. Bacterial plaque samples were collected with a curette from the deepest pocket in each quadrant and placed into separate tubes containing sterile 0.9% saline solution. Samples were examined at a magnification of ×400 by light microscopy. Cultivation for T. tenax was performed using the same samples, and the cultures were examined after 48 hours. E. gingivalis was present in the samples from 38 periodontitis patients, whereas T. tenax was present in samples from only 3 periodontitis patients. Both E. gingivalis and T. tenax were found together in the samples from 2 periodontitis patients. In total, 22 and 2 gingivitis patients were found to be infected with E. gingivalis and with T. tenax, respectively. Only 1 gingivitis patient was found to be infected with both E. gingivalis and T. tenax. In our study, oral protozoa were found in a high percentage in periodontitis and gingivitis patients. We believe that the prevalence of E. gingivalis and T. tenax should be determined via new studies and, in particular, the protection principles should be complied with.

    Full Text Available Background: One of the most common aesthetic problem encountered in the field of periodontology is gingival recession, which is, perceived by the patients as increase in length of teeth. The treatment of buccal gingival recession is a common requirement due to aesthetic concern or root sensitivity. This study was planned to evaluate the efficacy of PRF membrane compared to that of CTG in Miller's class I gingival recessions. Materials and Methods: 32 sites with Miller's Class I gingival recessions, out of which 16 sites received PRF (test and 16 sites received CTG (control. Each patient had undergone an initial periodontal treatment, including oral hygiene instructions, plaque control, and scaling and root planing, followed by re-evaluation. All clinical recordings; recession height, recession width, clinical attachment level, height of keratinized tissue, thickness of keratinized tissue, healing index and pain perception, were performed immediately before surgery (baseline and after 6 months interval following periodontal surgery. Results: In the test group, significant improvement was seen in terms CAL, REC-HT, REC-WD, HKT and TKT from baseline to 6 months. In the control group, only significant improvement seen was in REC-HT and TKT from baseline to 6 months. Comparison of both Healing Index and VAS score was done and it showed no significant difference between test and the control group except VAS at 1 week. Conclusion: Though CTG is a gold standard procedure, PRF can be used as an alternative procedure by keeping patient's comfort and recognition in mind.

    Full Text Available Oral squamous cell carcinoma (OSCC is the most common epithelial malignancy affecting the oral cavity. The most common sites for the development are lateral surface of tongue and floor of mouth; the least common sites are soft palate, gingiva, and buccal mucosa. Gingival squamous cell carcinoma can mimic a multitude of oral lesions and enlargements, especially those of inflammatory origin. In addition, predisposing and presenting factors are different from those of other OSCCs. Careful examination as well as routine biopsy are crucial for accurate diagnosis.

    This study determines prevalence of digit sucking and gingivitis, and association among age, sex, socioeconomic status, presence of digit-sucking habits, oral hygiene status (OHS), and gingivitis among a group of Nigerian children. Data of 992 children aged 1 to 12 years recruited through a household survey conducted in Osun State, Nigeria were analyzed. Information on age, sex, socioeconomic status, and history of digit-sucking habits were collected. Children were assessed for OHS and severity of gingivitis using the simplified oral hygiene index and the gingival index, respectively. Predictors of presence of gingivitis and poor oral hygiene were determined using multivariate logistic regression. One (0.2%) and 454 (93.0%) children aged 1 to 5 years had poor oral hygiene and mild gingivitis, respectively. Twenty-two (4.4%) and 361 (72.9%) children aged 6 to 12 years had poor oral hygiene and mild gingivitis, respectively. The odds of having poor oral hygiene (adjusted odds ratio [AOR]: 0.26; 95% confidence interval [CI]: 0.20 to 0.35; P oral hygiene and gingivitis. Increasing age and low socioeconomic status were factors that significantly increased chances of having poor oral hygiene and gingivitis.

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

    Probiotic Lactobacillus brevisCD2 (CD2) exerts anti-inflammatory properties by preventing nitric oxide synthesis. It is hypothesized that oral application of CD2 can inhibit naturally occurring gingival inflammation. Thirty-four healthy adults were randomized to receive L. brevisCD2 lozenges or placebo, three times daily for 14 days. The subjects refrained from oral hygiene, the extent of which was determined at various time points. In both groups, bleeding on probing scores increased continuously throughout the study except on day 3. In the placebo group, scores increased significantly from 9.50 at baseline to 14.75 and 14.81 on days 10 and 14, respectively (P gingival indices increased from baseline in both treatment groups, but no intergroup differences were observed. Measurements of immune markers in gingival crevicular fluid revealed increased production of nitric oxide in the placebo group (P gingivitis development in this model by downregulating an inflammatory cascade. © 2015 John Wiley & Sons A/S.

    The CT findings of pulmonary parenchymal injury due to blunt chest trauma in 73 patients and their clinical significance were analyzed. CT was obtained within 6 hours after trauma. Findings were analyzed according to the number of injured segments and severity which was classified into three grades. A correlation was also made with arterial blood PaO 2 and thoracic complications. Pulmonary parenchymal injury was identified in multisegmental portions bilaterally in most cases. It was most frequently observed in the posterior portion of the lung such as segment 6. More than 50% of lesions were classified as Grade 1. Pulmonary laceration, defined as patchy density with the cavitary lesion (Grade 3), was noted in 9.2%. There was a good correlation between extent of pulmonary injury and degree of hypoxia. The correlation of pneumothorax was also found with extensive lesion and frequency of Grade 3 lesion. Cases with pulmonary laceration tend to have extensive injury, and be related to the degree of hypoxia. In conclusion, CT evaluation of pulmonary parenchymal injury is valuable not only for morphological evaluation but also for estimation of hypoxia. (author)

    This study evaluates the safety and efficacy of Punica granatum var pleniflora mouthwash in treatment of diabetic gingivitis. In a double-blind randomized clinical trial 80 patients with diabetes mellitus and gingivitis were assigned to Golnaar and chlorhexidine 0.2% groups. After using mouthwashes for 2 weeks; participants underwent tooth scaling and the last visit was 2 weeks after scaling. The primary outcome measures were plaque, modified gingival and gingival bleeding indices, and pocket depth. Both interventions had significant improvement on all of the gingival and plaque indices (P < .001 for all indices). There were no significant differences between Golnaar and chlorhexidine in primary outcome measures except for modified gingival index for which Golnaar mouthwash had a superiority after 2 weeks when comparing with chlorhexidine (P = .039). Meanwhile, Golnaar mouthwash had no staining effect. Golnaar mouthwash is safe and effective in treatment of gingivitis in diabetic patients although further studies are recommended. © The Author(s) 2016.

    Full Text Available Aims & Objectives: Periodontal disease comprises a group of inflammatory conditions of the supporting tissues of the teeth that are caused by bacteria. The present study was undertaken to evaluate whether Oratest could be used as a sensitive indicator of plaque levels and gingivitis. Material and Methods: Hundred caries free patients visiting the out-patient department of A.E.C.S. Maaruti College of Dental Sciences and Research Centre, Banglore were selected according to predetermined selection criteria. The study consisted of two clinical stages: Stage 1. Recording of Plaque Index (Loe, 1967 and Gingival Index (Loe & Silness 1963 in the subjects. Stage 2. Performance of the Oratest and recording the scores in the same subjects. The Oratest was performed by rinsing the mouth with sterilized UHT (Ultra high temperature milk. About 3 ml of expectorated milk was added to a test tube containing the 0.12 ml of 0.1% methylene blue. The time required for colour change from blue to white attained at the bottom of the tube was recorded. Plaque Index, Gingival Index and Oratest scores were compared using Student t test. Pearson correlation test was applied to assess correlation between the indices and Oratest scores. Results:The results of the study showed that as age increased plaque and Gingival Indexes also increased whereas Oratest scores decreased. No significant difference between males and females was found in mean values of Plaque Index, Gingival Index and Oratest scores. Negative correlation was seen between Plaque Index and Oratest scores (r = 0.724 and also between Gingival Index and Oratest scores (r = 0.728. Conclusions: The study showed high correlation between the plaque and gingival indices and Oratest scores. This study validates Oratest as a predictable & sensitive test to assess periodontal disease.

    We investigated the effect of synthetic antimicrobial decapeptide KSL-W (KKVVFWVKFK) on normal human gingival fibroblast growth, migration, collagen gel contraction, and α-smooth muscle actin protein expression. Results show that in addition to promoting fibroblast adhesion by increasing F-actin production, peptide KSL-W promoted cell growth by increasing the S and G2/M cell cycle phases, and enhanced the secretion of metalloproteinase (MMP)-1 and MMP-2 by upregulating MMP inhibitors, such as tissue inhibitors of metalloproteinase (TIMP)-1 and TIMP-2 in fibroblasts. An in vitro wound healing assay confirmed that peptide KSL-W promoted fibroblast migration and contraction of a collagen gel matrix. We also demonstrated a high expression of α-smooth muscle actin by gingival fibroblasts being exposed to KSL-W. This work shows that peptide KSL-W enhances gingival fibroblast growth, migration, and metalloproteinase secretion, and the expression of α-smooth muscle actin, thus promoting wound healing.

    No oral niche can be considered to be segregated from the subjacent milieu because of the complex community behavior and nature of the oral biofilms. The aim of this study was to address the paucity of information on how these species are clonally related to the subjacent gingival crevice bacteria. We utilized a metagenomic approach of amplifying 16S rDNA from genomic DNA, cloning, sequencing and analysis using LIBSHUFF software to assess the genetic homogeneity of the bacterial species from two infected root canals and subjacent gingival crevices. The four niches studied yielded 186 clones representing 54 phylotypes. Clone library comparisons using LIBSHUFF software indicated that each niche was inhabited by a unique flora. Further, 42% of the clones were of hitherto unknown phylotypes indicating the extent of bacterial diversity, especially in infected root canals and subjacent gingival crevices. We believe data generated through this novel analytical tool shed new light on understanding oral microbial ecosystems. © 2014 Wiley Publishing Asia Pty Ltd.

    This study was aimed to evaluate the gingival crevicular fluid (GCF) and plasma transglutaminase-2 (TGM-2), total antioxidant capacity (TAC), total oxidant status (TOS), ferric reducing antioxidant power (FRAP) and thiobarbituric acid reactive substances (TBARS) in patients with chronic periodontal disease. Twenty patients with chronic periodontitis (CP), 20 patients with gingivitis and 20 healthy subjects were enrolled in the study. Clinical periodontal parameters including probing depth, clinical attachment level, plaque index and papillary bleeding index were recorded. GCF and plasma levels of TGM-2, TAC, TOS, TBARS and FRAP were analyzed. GCF TGM-2 was significantly lower in CP group than in gingivitis patients (P=0.006). GCF FRAP in CP and gingivitis groups was significantly lower than in healthy subjects (P0.05). GCF TGM-2 level was positively correlated with GCF TAC and negatively correlated with CAL. Decreased FRAP in GCF and plasma indicating lower antioxidant status of CP patients might suggest the role of oxidative stress in periodontitis. GCF TGM-2 data might suggest that TGM2 is associated with stabilization of the extracellular matrix and wound healing in periodontium rather than gingival inflammation. Copyright © 2017.

    Full Text Available Gingivitis is an inflammatory condition of gingival tissue and caused by the accumulation of dental plaque. Green tea (Camellia sinensis is a plant matter that has been shown to inhibit the growth of acidogenic bacteria and the formation of dental plaque. This study aimed to evaluate the effects of green tea extract on pH and volume of saliva of gingivitis patients. The subjects were 30 male gingivitis patients, 18-25 years old. The subjects were divided into 3 groups according to mouthrinse used (0.25% and 0.5% green tea extract, and 0.1% hexetidine as positive control. The subjects were instructed to gargle during five consecutive days in the morning and at night with 5 ml of the mouthrinse for 30 seconds. The data were taken in the beginning and at the sixth day. Data for salivary volume and pH before and after gargle were compared using MANOVA (p<0.05. The results showed signifcant differences in salivary pH, suggesting that green tea extract can increase the salivary pH of gingivitis patients, and that the 0.5% concentration was the most influential.

    C-reactive protein (CRP) is a type I acute phase reactant. A number of studies have reported elevated serum CRP levels in periodontitis subjects, which decrease following periodontal therapy. However, the data of interventional studies on gingival crevicular fluid (GCF) levels of CRP is very scarce. The aim of the present study was to evaluate the effect of periodontal therapy on GCF CRP levels in patients with gingivitis and chronic periodontitis. A total of 60 subjects were included in the study with 20 subjects each in following groups: I-Healthy, II-Gingivitis, III-Mild periodontitis based on community periodontal index scores. Periodontal therapy was performed on Group II and Group III patients. GCF was collected from each subject at baseline and 3 months after periodontal therapy. The collected sample was subjected to biochemical analysis to detect CRP levels by using commercially available chemiluminescence immunoassay kit. The present study demonstrated that the periodontitis group had a higher mean CRP level (2.49 ± 0.47 ng/ml) when compared with the Gingivitis group (1.40 ± 0.32 ng/ml) and Healthy group (0.56 ± 0.20 ng/ml). The mean CRP values after periodontal therapy were found to be reduced to 0.44 ± 0.23 ng/ml in Group II and 1.30 ± 0.36 ng/ml in Group III patients. Within the limitations of this study, it can be concluded that GCF CRP level progressively increases from periodontal health to disease. It can also be stated that there is a decrease in GCF CRP levels with periodontal treatment.

    Periodontal disease is a chronic inflammatory disease caused by bacterial infection that can lead to tooth loss. Gingival crevicular fluid can be collected easily and noninvasively. We previously discovered the presence of apolipoprotein B (apoB), the main constituent of low-density lipoprotein, and oxidized low-density lipoprotein (oxLDL) in the gingival crevicular fluid of healthy subjects. In this study, we investigated whether periodontal conditions affect the levels of apoB and oxLDL in gingival crevicular fluid. The study population comprised 11 patients with chronic periodontitis. A pair of gingival crevicular fluid samples was collected from each patient at a healthy site and at a site with periodontitis (baseline samples). Thereafter, gingival crevicular fluid samples were collected from the same patients again at 4 and 8 wk after scaling and root planing (SRP). The levels of apoB, oxLDL, protein and cytokines in gingival crevicular fluid, in addition to gingival crevicular fluid volume, were measured. At baseline, the levels of apoB and oxLDL in gingival crevicular fluid were higher at the sites with periodontitis than at the healthy sites. The levels of apoB and oxLDL at periodontal sites decreased after SRP. The level of oxLDL in gingival crevicular fluid correlated well with the probing pocket depth. The oxLDL : apoB ratio in gingival crevicular fluid was significantly higher than that in plasma. The levels of apoB and oxLDL in gingival crevicular fluid change according to the periodontal tissue conditions. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Abstract Background The aim of this study was to determine the presence of matrix metalloproteinase-8 in the gingival crevicular fluid (GCF of patients after acute myocardial infarction (AMI. Methods A total of 48 GCF samples from 20 AMI patients, hospitalized at the Department of Cardiology and Angiology of the Johannes Gutenberg University Mainz, were investigated. Besides the myocardial infarction all patients suffered from chronic periodontal disease. Fifty-one GCF samples from 20 healthy age matched individuals with similar periodontal conditions served as controls. The dental examination included the assessment of oral hygiene, gingival inflammation, probing pocket depth, clinical attachment level and X-ray examination. The study was only carried out after the positive consent of the regional ethic commission. A quantitative assessment of aMMP-8 levels in the gingival crevicular fluid was performed with the help of the DentoAnalyzer (Dentognostics GmbH, Jena, Germany, utilising an immunological procedure. Results The aMMP-8 concentrations found in the gingival crevicular fluid of the AMI patients significantly differed (p = 0.001; mean value 30.33 ± 41.99 ng/ml aMMP-8 from the control group (mean value 10.0 ± 10.7 ng/ml aMMP-8. These findings suggest that periodontal inflammation in AMI patients might be associated with higher MMP-8-values compared to the healthy controls. Conclusions The acute myocardial infarction seems to influence the degree of periodontal inflammation, thus the measurement of the gingival crevicular fluid MMP8 levels seems to be a helpful biochemical test to obtain information about the severity of the periodontal disease.

    Full Text Available One of the leading pathogenic mechanisms of chronic catarrhal gingivitis development in children is disorders in the system of child macroorganism and oral cavity microorganisms interrelation as a result of normal microflora inhibition against the background of general amount of opportunistic and pathogenic microorganisms. The oral cavity protective mechanisms condition plays an important role in this process. Due to this fact a perspective direction is to study the methods of mentioned pathology treatment using probiotics containing strains of normal microflora with high antagonistic, enzymatic and immune-modeling properties able to inhibit growth of pathogenic bacteria. Objective: to improve the common method of catarrhal gingivitis treatment in children by means of oral microbiocenosis correction on the local level. Materials and methods. The method of catarrhal gingivitis treatment in children with administration of the probiotic “BioGaia Prodentis” has been developed. 30 children at the age of 12 with clinical signs of chronic catarrhal gingivitis were treated and dynamically observed. The children were divided into two groups: the main (with application of the improved method and the group of comparison (the common method was applied. The periodontal tissue condition in children was assessed on the basis of OHI-S, PMA, CPI indices, and Schiller-Pisaref test. The oral cavity local immunity was assessed by means of lysozyme activity, the level of secretory immunoglobulin A, the degree of dysbiosis by urease activity detection in the oral fluid of children. Results. Administration of the drug “BioGaia Prodentis” in the complex of chronic catarrhal gingivitis treatment in children resulted in a quick reverse development of clinical signs. Among the children of the main group on the 3–4th day of treatment a tendency to subsidence of inflammatory signs was observed. In the group of comparison the signs such as hyperemia, swelling and

    Although nanoparticles (NPs) has afforded considerable benefits in various fields of sciences, several reports have shown their harmful effects, suggesting the necessity of adequate risk assessment. To clarify the mechanism of titanium dioxide nanoparticles (TiO2 NPs)-enhanced gingival inflammation, we conducted the full-scale metabolomic analyses of human gingival fibroblast cells treated with IL-1β alone or in combination with TiO2 NPs. Observation with transmission electron microscope demonstrated the incorporation of TiO2 NPs into vacuoles of the cells. TiO2 NPs significantly enhanced the IL-1β-induced prostaglandin E2 production and COX-1 and COX-2 protein expression. IL-1β reduced the intracellular concentrations of overall primary metabolites especially those of amino acid, urea cycle, polyamine, S-adenosylmethione and glutathione synthetic pathways. The addition of TiO2 NPs further augmented these IL-1β-induced metabolic changes, recommending careful use of dental materials containing TiO2 NPs towards patients with gingivitis or periodontitis. The impact of the present study is to identify the molecular targets of TiO2 NPs for the future establishment of new metabolic markers and therapeutic strategy of gingival inflammation.

    Systematically review the scientific evidence for efficiency of anti-inflammatory agents against gingivitis, either as solo treatments or adjunctive therapies. A protocol was developed aimed to answer the following focused question: "Are anti-inflammatory agents effective in treating gingivitis as solo or adjunct therapies?" RCTs and cohort studies on anti-inflammatory agents against gingivitis studies were searched electronically. Screening, data extraction and quality assessment were conducted. The primary outcome measures were indices of gingival inflammation. A sub-analysis was performed dividing the active agents into anti-inflammatory and other drugs. The search identified 3188 studies, of which 14 RCTs met the inclusion criteria. The use of anti-inflammatory or other agents, in general showed a higher reduction in the test than in the control in terms of gingival indexes and bleeding scores. Only two RCTs on inflammatory drugs could be meta-analysed, showing a statistically significant reduction in the GI in the experimental group [WMD = -0.090; 95% CI (-0.105; -0.074); p = 0.000]. However, the contribution of both studies to the global result was unbalanced (% weight: 99.88 and 0.12 respectively). Most of the tested material showed beneficial effect as anti-inflammatory agents against gingivitis, either as a single treatment modality or as an adjunctive therapy. © 2014 John Wiley & Sons A/S.

    The paper presents the results of studying the role of interleukins 4 and 6 in the pathogenesis of periodontal tissue diseases, specifically, in periodontitis, gingivitis and alveolitis. To study the nature of participation of IL-4 and IL-6 in the mechanisms of development of periodontitis, gingivitis and alveolitis. Studies were carried out on 80 nonlinear male rats with a body weight of 200.0 to 220.0 g divided into four groups of 20 animals each. The serum level of cytokines was determined by an enzyme immunoassay on the Multiscane Biotech analyzer using test systems manufactured by Caltag laboratories (USA). Statistical processing of the obtained digital results was processed with the help of the program "Statistica 8.0". Indicators of the reliability of changes between the control and intact groups also used the Student's test and the Excel program. The confidence level was taken at p gingivitis, where it decreased by 74% and its level became less with alveolitis and periodontitis, since in these diseases the level of IL-6 was practically the same from the control (p gingivitis, on the contrary, indicates the realization of a pathological reaction of the organism. The change in the levels of pro- and anti-inflammatory interleukins, especially with gingivitis, indicates a decrease in the body's adaptive reserves and may affect the further dynamics of the inflammatory process in the periodontal tissues.

    To evaluate the occurrence of supra-gingival calculus in children aged 6-9 years with disuse conditions such as: presence of dental pain, open-bite or erupting teeth. A cohort of 327 children aged 7.64±2.12 (range: 6-9) years (45% girls) were screened for presence of supra-gingival calculus in relation to open bite, erupting teeth and dental pain. Presence of dental calculus was evaluated dichotomically in the buccal, palatinal/lingual and occlusal surfaces. Plaque index (PI) and gingival index (GI) were also evaluated. Supra-gingival calculus was found in 15.9% of the children mainly in the mandibular incisors. Children aged 6-7 years had a higher prevalence of calculus as compared to children aged 7-8 years (23% vs. 13.5%, p=0.057) or 8-9 years (23% vs. 12.4%, p=0.078), respectively. No statistical relation was found between plaque and gingival indices and presence of calculus. The prevalence of calculus among children with openbite was significantly higher than that of children without open-bite (29.4% vs. 10.7%, p=0.0006, OR=3.489). The prevalence of calculus among children with erupting teeth in their oral cavity was higher than that of children without erupting teeth (17.7% vs. 9%, respectively, p=0.119). No statistical correlation was found between presence of dental pain and calculus (15.4% vs. 15.9%; p=0.738). Accumulation of calculus in children aged 6-10 years was found mainly in the mandibular incisors, decreased with age and was correlated with open-bite.

    This study described physical and psychosocial limitations associated with adult brachial plexus injuries (BPI) and patients' expectations of BPI surgery. During in-person interviews, preoperative patients were asked about expectations of surgery and preoperative and postoperative patients were asked about limitations due to BPI. Postoperative patients also rated improvement in condition after surgery. Data were analyzed with qualitative and quantitative techniques. Ten preoperative and 13 postoperative patients were interviewed; mean age was 37 years, 19 were men, all were employed/students, and most injuries were due to trauma. Preoperative patients cited several main expectations, including pain-related issues, and improvement in arm movement, self-care, family interactions, and global life function. Work-related expectations were tailored to employment type. Preoperative and postoperative patients reported that pain, altered sensation, difficulty managing self-care, becoming physically and financially dependent, and disability in work/school were major issues. All patients reported making major compensations, particularly using the uninjured arm. Most reported multiple mental health effects, were distressed with long recovery times, were self-conscious about appearance, and avoided public situations. Additional stresses were finding and paying for BPI surgery. Some reported BPI impacted overall physical health, life priorities, and decision-making processes. Four postoperative patients reported hardly any improvement, four reported some/a good deal, and five reported a great deal of improvement. BPI is a life-altering event affecting physical function, mental well-being, financial situation, relationships, self-image, and plans for the future. This study contributes to clinical practice by highlighting topics to address to provide comprehensive BPI patient-centered care.

    Tissues surrounding dental implants and teeth develop clinical inflammation in response to microbial stimuli. However, the literature suggests that differences exist in the microbial insult and inflammatory responses leading to gingivitis and peri-implant mucositis. In this pilot study, the authors use for the first time a systems biology approach to comprehensively evaluate clinical parameters, selected inflammatory markers, and the microbiome of subject-matched tooth and implant sites during native inflammation and in response to experimental plaque accumulation. Fifteen subjects with 2 posterior implants and corresponding contralateral teeth were examined at enrollment; at day 0, after reinstitution of gingival/mucosal health; at days 7, 14, and 21, during stent-mediated oral hygiene (OH) abstention; and at day 42, after resumption of OH. The subgingival microbiome was evaluated via 16S rRNA gene sequencing and 8 selected inflammatory markers measured in crevicular fluid. Comparison of teeth and implants via general linear models based on orthogonal polynomials showed similar responses in clinical parameters, inflammatory mediators, and proportions of individual microbial taxa during OH abstention. Implants, however, accumulated less plaque and underwent more heterogeneous shifts in microbiome structure. A multilevel, within-group, sparse partial least squares analysis of covariation of microbial, inflammatory, and clinical parameters throughout all study visits found inflammation around teeth and implants positively correlated with IL-1 alpha and IL-1 beta and with the proportions of Selenomonas, Prevotella, and 5 species-level phylotypes. Gingivitis, however, showed a stronger positive correlation with lactoferrin and IL-1ra and a stronger negative correlation with Rothia. Peri-implant mucositis, on the contrary, correlated positively with certain microbial taxa not associated with gingivitis by a previous study or the current one. In summary, differences

    Full Text Available Introduction Root coverage supported with complete regeneration of lost periodontal tissues represents the ultimate goal of gingival recession treatment. Objective This study was designed to evaluate clinical effectiveness of platelet rich plasma gel (PRP with connective tissue graft (CTG in the treatment of gingival recession. METHOD 15 gingival recessions Miller class I or II were treated with CTG and PRP (group PRP. Connective tissue graft was harvested from the premolar region using trap door technique. After elevation of the flap, the regional bone and root surface were smeared with activated PRP gel. CTG was also irrigated with PRP gel before placement over the exposed root surface and local bone. Fixed CTG was covered with a coronally advanced flap. The same number of gingival recessions were treated with CTG in combination with the coronally advanced flap with no PRP gel (group TVT. Clinical recordings included recession depth (RD, probing depth (PD, clinical attachment level (CAL and keratinized tissue width (KT before and 1 year after mucogingival surgical treatment. Results Mean value of RD was significantly decreased from 4.93±0.86 mm to 0.60±0.37 (p<0.01 with CTG and PRP and from 4.76±0.74 mm to 0.63±0.29 mm (p<0.01 in CTG group. This difference was not statistically significant. Results of the keratinized tissue width showed significant increase from 0.88± 0.30 mm presurgery to 3.78±0.49 mm (p<0.01 six months after treatment in PRP group and from 0.90±0.34 mm to 3.15±0.41 in TVT group (p<0.01. This difference was statistically significant (p>0.05. No statistically significant differences were observed between treatment groups in CAL and PD. Conclusion Clinical results validate both procedures as effective and highly predictable surgical techniques in solving gingival recession problem. Histological evaluation may confirm advantage of PRP use related to regeneration of periodontal tissues. .

    The anterior corticospinal tract (CST) has been suggested as one of the ipsilateral motor pathways, which contribute to motor recovery following stroke. In this study, we report on a patient who showed deterioration of pre-existing hemiparesis due to an injury of the ipsilateral anterior CST following a pontine infarct, as evaluated by diffusion tensor tractography (DTT). A 55-year-old male patient showed quadriparesis after the onset of an infarct in the right pontine basis. He had history of an infarct in the left middle cerebral artery territory 7 years ago. Consequently, he showed right hemiparesis before onset of the right pontine infarct. Following this, his right hemiparesis deteriorated whereas his left hemiparesis newly developed. The DTTs for whole CST of the right hemisphere in the patient and both hemispheres in control subjects descended through the known CST pathway. By contrast, the DTT for the left whole CST of the patient showed a complete injury finding. The DTTs for the anterior CST of control subjects passed through the known pathway of the CST from cerebral cortex to medulla and terminated in the anterior funiculus of the upper cervical cord. However, the DTT for right anterior CST in the patient showed discontinuation below the right pontine infarct. It appeared that the deterioration of the pre-existing right hemiparesis was ascribed to an injury of the right anterior CST due to the right pontine infarct.

    The aim of the present study was to evaluate in vitro the biological behavior of human gingival fibroblasts cultured on two different titanium surfaces. Titanium test disks were prepared with a machined, relatively smooth (S) surface or a rough surface (O) obtained by a double acid etching procedure. Primary cultures of human gingival fibroblasts were plated on the experimental titanium disks and cultured up to 14 days. Titanium disk surfaces were analysed by scanning electron microscopy (SEM). Cell proliferation and a quantitative analysis by ELISA in situ of ECM components as CoI, FN and TN were performed. Results have shown different effects of titanium surface microtopography on cell expression and differentiation. At 96 hours of culture on experimental surfaces human gingival fibroblasts displayed a favourable cell attachment and proliferation on both surfaces although showing some differences. Both the relatively smooth and the etched surfaces interacted actively with in vitro cultures of human gingival fibroblasts, promoting cell proliferation and differentiation. Results suggested that the microtopography of a double acid-etched rough surface may induce a greater Co I and FN production, thus conditioning in vivo the biological behaviour of human gingival fibroblasts during the process of peri-implant soft tissue healing.

The analysis was performed referring to two groups: "injury group" - in which the injury was the main reason for quitting football, and "other group" - in which the female player stopped playing football due to all other factors. Thirty percent of former Polish female football players terminated their career due to a long-term treatment for an injury. Over 27 percent (27.7%) females had ended their careers because they were not able to reconcile sports with work/studying. Over 10 percent (10.8%) of former football players reported that becoming a wife and/or mother was the reason for career termination. Losing motivation and interest in sport was reported by 9.2%(n=6) of present study participants who decided to terminate the career due to non-injury reasons. The results clearly show that more effort is needed to support female football players, especially after an injury, so that they do not quit the sport voluntarily.

    Periodontal diseases are often induced by periodontopathogens, which are always exposed to certain innate immune factors in gingival crevicular fluid, including human β-defensin-2 (hBD-2). This study aims to investigate the relationship among periodontopathogens, clinical parameters and hBD-2 expression. Thirty-two healthy controls, 42 patients with chronic gingivitis and 95 patients with chronic periodontitis were recruited in Guangxi, China. Bleeding index, probing depth and clinical attachment level were measured for all teeth including mesiobuccal, buccal, disobuccal, mesiolingual, lingual, disolingual six sites of all patient. Gingival crevicular fluid samples were collected from the study sites. The prevalence and copy numbers (CN) of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Treponema denticola, Tannerella forsythia and total bacteria in gingival crevicular fluid were quantified by real-time PCR. The hBD-2 concentration in gingival crevicular fluid was measured by ELISA. Both the prevalence and the CN of A. actinomycetemcomitans, P. gingivalis, T. denticola and T. forsythia were higher in patients with chronic periodontitis than in healthy controls and patients with chronic gingivitis; however, there was no significant difference in the prevalence of P. intermedia among the three study groups, and the highest CN was found in patients with chronic gingivitis, rather than in patients with chronic periodontitis. The loads of P. gingivalis, P. intermedia, T. denticola and total bacteria were positively related to probing depth, bleeding index and clinical attachment level. The concentration of hBD-2 in gingival crevicular fluid was higher in patients with chronic gingivitis and in patients with chronic periodontitis than in healthy controls. In addition, the hBD-2 concentration was positively related to the CN of P. gingivalis, T. forsythia and total bacteria, as well as to bleeding index and probing depth. The

    South and Southeast Asia and Latin American together comprise 46 countries and are home to approximately 40% of the world population. The sociopolitical and economic heterogeneity, tropical climate, and malady transitions characteristic of the region strongly influence disease behavior and health care delivery. Acute kidney injury epidemiology mirrors these inequalities. In addition to hospital-acquired acute kidney injury in tertiary care centers, these countries face a large preventable burden of community-acquired acute kidney injury secondary to tropical infectious diseases or animal venoms, affecting previously healthy young individuals. This article reviews the epidemiology, clinical picture, prevention, risk factors, and pathophysiology of acute kidney injury associated with tropical diseases (malaria, dengue, leptospirosis, scrub typhus, and yellow fever) and animal venom (snakes, bees, caterpillars, spiders, and scorpions) in tropical regions of Asia and Latin America, and discusses the potential future challenges due to emerging issues.

    Gingival recession is a common occurrence and patients often report to dental clinic with associated problems such as root surface hypersensitivity, esthetic concerns, cervical root abrasions, and root caries that make it a concern for patients. Based upon the fact that gingival recession is an enigma for clinicians because of multitude of etiological factors and plethora of treatment modalities present for its treatment, a survey was conducted to assess knowledge as well as opinion about most common etiology, classification, and preferred treatment of gingival recession and to evaluate the interest and satisfaction of dentists in practicing periodontics. Study design consisted of a cross-sectional online survey, conducted among dentists practicing in state of Punjab, India, in the month of April 2011. A structured online questionnaire consisting of 17 questions evaluating the interest of dentists in periodontics based on knowledge about gingival recession (most of them giving the possibility of multiple choices of answers) was sent to about 300 dentists. Pearson Chi-Square and Mann-Whitney U tests were used for statistical analysis of data collected. P ≤ 0.05 was considered as statistically significant and P ≤ 0.01 considered as highly significant. A greater proportion of periodontists had better knowledge about etiology (P = 0.07), classification (P = 0.000), and treatment of gingival recession (P = 0.000). A greater number of periodontists opted for the surgical modalities to correct the defects produced by gingival recession as compared to non-periodontists and had better interest (P = 0.000) and satisfaction (P = 0.000) in practicing periodontics. The results elucidated that periodontists had better interest and satisfaction in practicing periodontics, and were more inclined towards surgical correction of gingival recession as compared to non-periodontists.

    Full Text Available Thirty male subjects aged around 20-30 years old, with complete anterior teeth, no inter proximal caries and good general health conditions were selected by using simple random sampling. The anterior teeth were divided into 2 segments right side for 11, 12, 13 and left side for 21, 22, and 23. These two sites were treated by different way for comparing two treatment variables, between scaling therapy alone and scaling therapy with adjunction of Chlorhexidine (CHX 0.2%. Gingival Index (GI score was used to determine the gingivitis status of the subjects. Clinical experiment showed that the duration of healing process in subjects treated with scaling with adjunction of CHX 0.2% was faster than scaling therapy alone group. However, in the statistical analysis, there was no significant difference because of several factors. In conclusion, it was found that CHX 0.2% had the efficacy to enhance the healing process in the marginal gingivitis patient that was treated by scaling therapy, but further study using CHX 0.2% with longer duration time should be done to achieve more pronounce effect

    Hydronephrosis caused by retroperitoneal hematoma after a seatbelt injury is a unique clinical entity. A 21-year-old man, who had been wearing a seatbelt, was brought to our hospital after a motor vehicle collision, complaining of abdominal pain. Computed tomography (CT) revealed retroperitoneal hematoma in the upper pelvic region. Since he was hemodynamically stable throughout admission, he was managed conservatively. Seventeen days after initial discharge, the patient revisited our emergency department due to right back pain. CT scans indicated retroperitoneal hematoma growth resulting in hydronephrosis of the right kidney. Laparoscopic drainage of the retroperitoneal hematoma was successfully performed. His symptoms resolved after the surgery. Follow-up CT scans three months later demonstrated complete resolution of the hydronephrosis and retroperitoneal hematoma. Our case highlights a patient with delayed hydronephrosis because of retroperitoneal hematoma expansion after a seatbelt injury.

    Full Text Available BACKGROUND Oil pulling has been used extensively as a traditional remedy for many years. It is supposed to cure oral and systemic diseases, but the evidence is minimal. Intraorally it is supposed to cause strengthening of teeth, gums, and the jaw and to prevent decay, oral malodour, bleeding gums, dryness of the throat and cracked lips. The aim of this study was to evaluate the effect of oil pulling with flaxseed oil on plaque induced gingivitis and to compare its efficacy with chlorhexidine mouthwash. MATERIALS AND METHODS A total of 20 teenaged individuals attending the Out Patient - Department of Dentistry with plaque-induced gingivitis were selected for this study. They were divided randomly into the study or oil pulling group (Group I and the control or chlorhexidine group (Group II with 10 subjects in each group. Plaque index and modified gingival index scores were recorded for the selected individuals of both the groups. The study group was subjected to oil pulling with flaxseed oil every day in the morning before brushing whereas the control group used chlorhexidine mouth rinse. Reassessment of the index scores was done after 30 days in both the groups. RESULTS There was a statistically significant reduction of the pre- and post-values of the plaque and modified gingival index scores in both the study and control groups (P <0.001. CONCLUSION The oil pulling therapy with flaxseed oil is thus an effective adjuvant in reducing plaque-induced gingivitis.

    Fusobacterium nucleatum is one of the most abundant gram-negative bacilli colonizing the subgingival plaque and closely associated with periodontal disease. However it is unclear whether F. nucleatum is involved in gingival inflammation under orthodontic appliance. A novel adhesin, FadA, which is unique to oral Fusobacteria, is required for F. nucleatum binding and invasion to epithelial cells and thus may play an important role in colonization of Fusobacterium in the host. In this study, we evaluated the prevalence of F. nucleatum and its virulence factor FadA adhesion gene (fadA) in 169 subgingival biofilm samples from 55 cases of gingivitis patients with orthodontic appliances, 49 cases of gingivitis patients without orthodontic treatment, 35 cases of periodontitis patients and 30 cases of periodontally healthy people via PCR. The correlations between the F. nucleatum/fadA and gingivitis index(GI)was also analyzed. The detection rate of F. nucleatum/fadA in periodontitis group and non-orthodontic gingivitis group was higher than the other two groups (pgingivitis group than in health people (pgingivitis and periodontal disease compared with orthodontic gingivitis.

    Full Text Available Background/Aim. Gingival recession progression in clinical practice as an ethiological factor of periodontal diseases, and symptoms of the disease have caused the development of various surgical procedures and techniques of the reconstruction of periodontal defects. The aim of this study was to verify efficacy of surgical procedures that include connective tissue autotransplants with periosteum and guided tissue regeneration for the treatment of gingival recession. Methods. The study included 20 teet with gingival recession, Müller class II and III. Ten teeth with gingival recession were treated with resorptive membrane and coronary guided surgical flap (GTR group. On the contralateral side 10 teeth with gingival recession were treated with connective tissue autotransplants with periosteum in combination with coronary guided surgical flap (TVT group. We measured the degree of epithelial attachment (DEA, width of subgingival curettage (WGC and vertical deepness of recession (VDR. For statistical significance we used Student's ttest. Results. The study revealed statistical significance in reducing VDR by both used treatments. Root deepness in GTR and TVT group was 63.5%, and 90%, respectively. With both surgical techniques we achieved coronary dislocation of the epithelial attachment, larger zone of gingival curettage, and better oral hygiene. Conclusion. Current surgical techniques are effective in the regeneration of deep periodontal spaces and the treatment of gingival recession. Significantly better results were achieved with the used coronary guided surgical flap than with guided tissue regeneration.

    The oral cavity is frequently affected in patients with inflammatory bowel disease (IBD), especially in patients with Crohn's disease (CD). Periodontitis is thought to influence systemic autoimmune or inflammatory diseases. We aimed to analyze the relationship of periodontitis and gingivitis markers with specific disease characteristics in patients with IBD and to compare these data with healthy controls. In a prospective 8-month study, systematic oral examinations were performed in 113 patients with IBD, including 69 patients with CD and 44 patients with ulcerative colitis. For all patients, a structured personal history was taken. One hundred thirteen healthy volunteers served as a control group. Oral examination focussed on established oral health markers for periodontitis (bleeding on probing, loss of attachment, and periodontal pocket depth) and gingivitis (papilla bleeding index). Additionally, visible oral lesions were documented. Both gingivitis and periodontitis markers were higher in patients with IBD than in healthy control. In univariate analysis and logistic regression analysis, perianal disease was a risk factor for periodontitis. Nonsmoking decreased the risk of having periodontitis. No clear association was found between clinical activity and periodontitis in IBD. In only the CD subgroup, high clinical activity (Harvey-Bradshaw index > 10) was associated with 1 periodontitis marker, the loss of attachment at sites of maximal periodontal pocket depth. Oral lesions besides periodontitis and gingivitis were not common, but nevertheless observed in about 10% of patients with IBD. IBD, and especially perianal disease in CD, is associated with periodontitis. Optimal therapeutic strategies should probably focus on treating both local oral and systemic inflammation.

    Full Text Available Overgrowth of keratinized gingival tissues is a common condition and is described under variety of names. Causes of such enlargement can be medications, hereditary, and/or local irritating factors. Mutation in SOS1, son-of-sevenless gene, is thought to be responsible for hereditary gingival fibromatosis. This report shows a case of 19-year-old male and his 15-year-old sister, with a chief complaint of overgrowth of gingival and irregularly placed teeth. A similar overgrowth was also found in other members of the same family, without any drug history or syndromic conditions. An occurrence of the disease has been found in two generations of this family and therefore, it may be following autosomal dominant trait of inheritance. Since it is idiopathic and has a genetic cause for its occurrence, it cannot be prevented. Both cases underwent a surgical intervention to rectify the abnormality and were followed from 6 months to 1 year, during which there was no recurrence.

    Objectives. This study aimed to investigate the efficacy of a Schinus terebinthifolius (ST) mouthwash in reducing gingival inflammation levels (GI) and biofilm accumulation (BA) in children with gingivitis. Methods. This was a randomized, controlled, triple blind, and phase II clinical trial, with children aged 9–13 years (n = 27) presenting with biofilm-induced gingivitis. The sample was randomized into experimental (0.3125% ST, n = 14) and control (0.12% chlorhexidine/CHX, n = 13) groups. Products were masked as regards color, flavor and aroma. Intervention protocol consisted in supervised rinsing of 10 mL/day for 01 minute for 10 days. Gingival bleeding and simplified oral hygiene indexes were used to assess the efficacy variables, measured at baseline and after intervention by calibrated examiners. Data were statistically treated with paired t-test, unpaired t-test, and Wilcoxon and Mann-Whitney tests (α = .05). Results. It was found that both ST and CHX were able to significantly reduce GI levels after 10 days (P 0.05). CHX was the only product able to significantly reduce BA after 10 days when compared to baseline (P < 0.05). Conclusion. ST mouthwash showed significant anti-inflammatory activity (equivalent to CHX), but it was not able to reduce biofilm accumulation. PMID:23843886

    This study was performed to assess the field efficacy of a professional and home-care barrier gel against the development of plaque, calculus, gingival bleeding, and gingivitis in client-owned cats over a 56-day period compared with negative controls. In a randomized, negative-controlled, outcome evaluator-blinded, client-owned animal clinical field study, 31 cats were evaluated to assess if the barrier gel dental product was effective in cats. Following an enrollment-qualification assessment and enrollment of each cat, all cats received a professional dental cleaning, including polishing and irrigation. Following cleaning, a post-cleaning assessment was performed by the evaluator. Then, using a pre-developed randomization schedule, cats were assigned to the treated or control group. The professional version of the barrier gel was applied to the treated group on day 0. The negative-control group patients did not receive any applications of the barrier gel following dental cleaning. Treated-group cats were brought back to the clinic for subsequent applications of the home-care version of the barrier gel, applied by a non-blinded trained assistant. The home-care version product applications began on day 14 and then were applied weekly (days, 21, 28, 35, 42, 49 and 56) through day 56. All cats enrolled in the study underwent full oral examinations and assessments by the blinded evaluator on or about their respective days 28 and 56. At these evaluations, the evaluator performed standardized assessments for plaque, calculus, gingivitis, and gingival bleeding. Numeric scores were assigned for each assessment using predetermined target teeth to ensure consistency. Using these assessment scores, statistical analyses were performed to determine the efficacies against plaque and calculus deposition; additionally, measurements of gingivitis and gingival bleeding were assessed.

    We here investigated whether experimental gingivitis enhances systemic markers of inflammation which are also known as surrogate markers of atherosclerotic plaque development. Gingivitis is a low-level oral infection induced by bacterial deposits with a high prevalence within Western populations. A potential link between the more severe oral disease periodontitis and cardiovascular disease has already been shown. 37 non-smoking young volunteers with no inflammatory disease or any cardiovascular risk factors participated in this single-subject interventional study with an intra-individual control. Intentionally experimental oral inflammation was induced by the interruption of oral hygiene for 21 days, followed by a 21-days resolving phase after reinitiation of oral hygiene. Primary outcome measures at baseline, day 21 and 42 were concentrations of hsCRP, IL-6, and MCP-1, as well as adhesion capacity and oxLDL uptake of isolated blood monocytes. The partial cessation of oral hygiene procedures was followed by the significant increase of gingival bleeding (34.0%, Pgingivitis. Bacterial-induced gingival low-level inflammation induced a systemic increase in inflammatory markers. Dental hygiene almost completely reversed this experimental inflammatory process, suggesting that appropriate dental prophylaxis may also limit systemic markers of inflammation in subjects with natural gingivitis.

    Sánchez, Isis M; Gaud-Quintana, Sadja; Stern, Jacob K

    Lip repositioning surgery to address excessive gingival display induced by different etiologies has received major attention recently. Several techniques and variations have been reported, including myotomy or repositioning of the levator labii superioris muscle, Le Fort impaction, maxillary gingivectomies, botulinum toxin injections, and lip stabilization. This study reports a case of excessive gingival display treated by a modified combined approach. A 25-year-old woman with a 4- to 8-mm gingival display when smiling caused by a combination of short clinical crowns induced by an altered passive eruption and hypermobility of the upper lip underwent a staged esthetic crown-lengthening procedure followed by a modified lip repositioning technique. A description of the technique and a comparison with other modes of therapy is discussed. This modified approach for treating the hypermobile lip included a bilateral removal of a partial-thickness strip of mucosa from the maxillary buccal vestibule without severing the muscle, leaving the midline frenum intact and suturing the lip mucosa to the mucogingival line. The narrower vestibule and increased tooth length resulted in a symmetric and pleasing gingival display when smiling that remained stable over time. With proper diagnosis and sequence of therapy, modified lip repositioning surgery combined with esthetic crown lengthening can be used predictably to treat excessive gingival display and enhance smile esthetics.

    The expression of A Disintegrin and Metalloproteinase 8 (ADAM8) is associated with several inflammatory diseases. Elevated ADAM8 levels have been shown in gingival crevicular fluid of patients with chronic periodontitis. The objective of this study was to investigate ADAM8 expression in chronic periodontitis tissues compared with that in normal tissues. ADAM8 expression and its inductive mechanism were examined in human gingival epithelial cells (HGECs) and human gingival fibroblasts. Total RNA and protein were extracted from gingival biopsies of 33 patients with chronic periodontitis and those of 23 healthy volunteers. ADAM8 mRNA and protein expression was analyzed by real-time polymerase chain reaction, immunoblotting and immunohistochemistry. ADAM8 expression in control and stimulated cells in the presence or absence of specific inhibitors for mitogen-activated protein kinase pathways was assayed by real-time polymerase chain reaction, immunoblotting, flow cytometry and immunofluorescence. ADAM8 mRNA and protein expression in chronic periodontitis tissues was significantly greater than that in normal tissues (p chronic periodontitis tissues (p chronic periodontitis tissues and localized within gingival epithelium, consistent with an upregulation of ADAM8 expression in F. nucleatum-stimulated HGECs, suggesting a possible role of ADAM8 in innate immunity of periodontal tissue. © 2016 John Wiley & Sons A/S.

    Cowden syndrome, also known as multiple hamartoma syndrome, is a rare autosomal dominant disorder characterized by multiple hamartomas and a high risk of development of malignancy. Oral findings, such as papillomatous lesions and fibromas, are common features; however, a periodontal phenotype has not been reported previously. Therefore, this report presents a case of gingival overgrowth associated with Cowden syndrome, its successful surgical management, and the 12-month follow-up results. Additionally, we discuss the implications for clinicians. A 23-year-old woman was referred to the Department of Periodontics, Piracicaba Dental School, presenting with generalized gingival overgrowth. A detailed dental and medical history and clinical examination confirmed the systemic diagnosis of Cowden syndrome. Histology, radiographs, and clinical data document the entire clinical approach and follow-up. Clinically, there were minor signs of recurrence of gingival overgrowth in a 12-month period after gingivectomy; however, papular lesions reappeared in keratinized gingiva immediately after healing. No signs of bone loss related to the systemic condition were observed radiographically. Histologically, a dense connective tissue with a moderate chronic inflammatory infiltrate and epithelial acanthosis, which is characteristic of gingival hyperplasia, were demonstrated. Gingival overgrowth may occur as an oral phenotype related to Cowden syndrome and can be successfully treated by means of external bevel gingivectomy, followed by regular maintenance therapy, contributing to the patient's well-being, both functionally and esthetically.

    The mechanism of crop injury by nitrogen dioxide gas was investigated by exploring kidney bean, cucumber, tomato, egg plant, and spinach plants 6.0 to 17 ppM NO/sub 2/ under various conditions. The application of aqueous oxyethylene decasanol on crop leaves reduced the injury due to the gas, expecially on the lower leaf sides. Leaves exposed to NO/sub 2/ in the dark showed severer injury and contained more nitrite anion than those exposed to NO/sub 2/ in the light. Leaves smeared with an aqueous sodium nitrite solution showed the same type of injury as that induced by NO/sub 2/. After treatment with 3-(3,4-dichlorophenyl)-1,1- dimethylurea, the leaves became more susceptible to the gas even under light and formed more nitrite anion than controls. Plants grown in nitrate-nitrogen cultures were less susceptible to NO/sub 2/ damage than those grown in ammonia-nitrogen cultures or cultures without nitrogen and contained less nitrite anion than others. Plant injury by gaseous nitrogen dioxide appeared to be caused by nitrite anion. Susceptibility to NO/sub 2/ depended on the amount of the gas taken in by stomata and on the physiological activity of the plant which reduces the anion. The reduction is carried out by nitrite reductase. The photochemical reduction by reductase in chloroplasts appears to be related to the injury-reducing effect of light.

    Sjögren's syndrome is an autoimmune disease characterized by xerostomia and keratoconjunctivitis sicca. The relationship between xero-stomia and proliferative activity in human gingival epithelium is not known. Proliferating cell nuclear antigen (PCNA) is a nuclear protein associated with the cell cycle. Nuclear PCNA immunoreactivity is found in the proliferative compartment of normal tissues. The aims of this study were to evaluate PCNA expression in oral gingival epithelium of healthy and inflamed gingiva obtained from patients with Sjögren's syndrome, and to compare the results to age- and gender-matched subjects with normal salivary function. Eighteen Sjögren's syndrome patients and 28 controls (14 with chronic periodontitis and 14 with no clinical evidence of periodontal disease) were included in the study. Biopsies were obtained from both inflamed and healthy gingiva. The expression of PCNA was evaluated in formalin-fixed, paraffin-embedded gingival samples using an immunoperoxidase technique and PC10 monoclonal antibody to PCNA. PCNA expression was observed both in the basal and suprabasal layers, and was found to be more prominent in the suprabasal layers. Proliferative index (PI) in inflamed gingiva was significantly lower in the Sjögren's syndrome group. However, no significant difference was observed between the study and control groups with respect to PI in healthy gingiva. In both groups, PI was found to be increased due to inflammation. Our data indicate that proliferative activity is observed in the suprabasal layers and, less frequently, in the basal layer. Inflammation caused increased proliferative activity. However, this positive effect of inflammation on epithelial cell proliferation decreased significantly with a lack of saliva. Therefore, it appears that saliva-derived biological mediators may also contribute to increased proliferative activity observed during inflammation.

    The aim of the present study was to determine the facial gingival profiles of teeth with a healthy periodontium in an Asian population. A total of 51 patients with a healthy periodontium were examined. Gingival thickness (GT) and gingival width (GW) were assessed at the maxillary and mandibular incisors to the first molars. GT was measured by transgingival probing (GT-TGP), and probe visibility through the marginal gingiva (GT-TRAN) was assessed. Results between groups (anterior and posterior, tooth types) were analyzed using one-way analysis of variance and t-test. The mean age was 30.3±11.4 years, with 27 females and 24 males. The mean GT-TGP was 1.39±52 mm, while the mean GW was 4.59±1.34 mm. Considerable intra-individual and interindividual variation in GT (TGP and TRAN) was noted. GT increased from the anterior to posterior, and was thinnest at the mandibular centrals to the first premolars and maxillary canines. GT-TGP and GW were influenced by tooth type, plaque, recession, and TRAN, but not age, sex, or ethnicity. GW were recorded lowest at the mandibular canines and all premolars. Thin gingiva was recorded at 63.8%-92% (GT-TGPTGP and GT-TRAN. © 2017 John Wiley & Sons Australia, Ltd.

    Objective To evaluate the effect of Aloe vera, chlorine dioxide, and chlorhexidine mouth rinses on plaque and gingivitis in orthodontic treatment. Materials and methods A randomized single-center, single-blind, parallel group, controlled trial was conducted among 90 subjects undergoing fixed orthodontic treatment. The subjects were randomly divided into one of the three study groups (Aloe vera, chlorhexidine, chlorine dioxide). Plaque and gingivitis were assessed using modified Silness and Loe Plaque Index and Gingival Index at baseline and at follow-up after 15 days. Paired t-test and ANOVA with post hoc Dunnett test were used. A p-value of <0.05 was considered statistically significant. Results A total of 85 participants completed the study; among them, 40 were male and 45 were female. There was significant reduction in mean plaque and gingival scores in all the 3 groups at follow-up when compared to baseline. A significantly higher reduction (plaque and gingival scores) was found in chlorhexidine when compared with the Aloe vera group. However, no significant difference was seen between chlorhexidine and chlorine dioxide with respect to mean reduction in plaque and gingival scores. Conclusion Chlorine dioxide can be a suitable and economical alternative for chlorhexidine. Further long-term studies are recommended for evaluating their effectiveness. PMID:26937371

    Background Gingival inflammation and periodontal disease are the common complications of fixed dental prosthesis. They can be overcome by good oral hygiene maintenance. Objective The objective of this study was to assess the oral hygiene and gingival condition in patients after placement of fixed dental prosthesis for a period of six months. It was also analyzed how factors like type of fixed dental prosthesis (Single crown, fixed partial denture) and material (Metal, Porcelain fused to metal) are statistically associated with oral hygiene and gingival health. Method The sample consisted of 50 patients visiting the Dental Outpatient Department of Dhulikhel Hospital. The oral examinations were conducted using basic diagnostic tools (Mouth mirror, periodontal probe and explorer). Teeth and gingiva were examined using the Plaque and Gingiva Index by Silness and Löe. The examinations were conducted after 14 days and six months after placement of fixed dental prosthesis along with the oral hygiene instructions. Paired sample t-test were done to find statistical association using SPSS 16.0. Result Our results revealed no significant difference in plaque index among patients with single crown whereas fixed partial denture showed statistical significance. No significant differences were found for type of material. The statistical analysis showed similar results for gingival index. Conclusion Our research showed that single crown had no significant difference on Plaque index and Gingival index of the patient after 14 days and six months, whereas, Fixed partial denture showed significant difference. Both metal and porcelain fused to metal crown revealed no statistically significant difference on Plaque index and Gingival index.

    Gingival invaginations develop after tooth extraction and subsequent orthodontic space closure. Aetiological factors and long-term effects of gingival invaginations on oral health are nearly unknown. In addition, preventive or therapeutic strategies are rare. This prospective clinical study employing the split mouth technique was performed to investigate the effect of extraction socket augmentation with a synthetic nanocrystalline hydroxyapatite (NanoBone(®) Artoss, Rostock, Germany) on the incidence and degree of gingival invaginations. A total of 10 orthodontic patients with need for symmetric premolar extractions offering a total of 28 extractions were included in this trial. The study plan provided one extraction site to be augmented with synthetic nanocrystalline hydroxyapatite (NanoBone(®)), the other served as control. After primary wound healing, space closure was performed under defined biomechanical conditions. After space closure was accomplished, occurrence and degree of gingival invaginations as well as probing depths of the adjacent teeth mesial and distal to the extractions were determined and dental radiographs were taken. The degree of gingival invaginations and probing depths mesial and distal of the extraction were significantly reduced on NanoBone(®) augmented extraction sites. In addition, 70% of the radiographs revealed translucent and hyperdense areas on the intervention side after space closure. Apical root resorption was found in 2 patients on both the NanoBone(®) side and the control side. Ridge preservation with NanoBone(®) appeared to reduce the severity of gingival invaginations. Further investigation on long-term effects is mandatory to eliminate the appearance of adverse effects.

    Periodontitis is the most frequently diagnosed health problem in cats yet little is known about the bacterial species important for the disease. The objective of this study was to identify bacterial species associated with health, gingivitis or mild periodontitis (gingivitis or mild periodontitis. Pyrosequencing of the V1-V3 region of the 16S rDNA from these plaque samples generated more than one million reads and identified a total of 267 operational taxonomic units after bioinformatic and statistical analysis. Porphyromonas was the most abundant genus in all gingival health categories, particularly in health along with Moraxella and Fusobacteria. The Peptostreptococcaceae were the most abundant family in gingivitis and mild periodontitis. Logistic regression analysis identified species from various genera that were significantly associated with health, gingivitis or mild periodontitis. The species identified were very similar to those observed in canine plaque in the corresponding health and disease states. Such similarities were not observed between cat and human at the bacterial species level but with disease progression similarities did emerge at the phylum level. This suggests that interventions targeted at human pathogenic species will not be effective for use in cats but there is more potential for commonalities in interventions for cats and dogs.

    The gingival biotype is of utmost importance for esthetics and biologic function. Anatomical characteristic of periodontium such as gingival thickness (GT), width of keratinized gingiva, and alveolar bone morphology will determine the behavior of periodontium when subjected to physical, chemical, or bacterial insult or during therapeutic procedure. The aim of this study was to correlate the GT with gingival width (GW), probing depth (PD), and papillary fill (PF) in relation to maxillary anterior region. Undergraduate dental students and interns from a dental college in Navi Mumbai were enrolled in the study according to the inclusion criteria. Six teeth per subject were assessed; a total of 2178 maxillary anterior teeth were examined. Subjects were examined clinically for GT, width of keratinized gingiva, pocket depth, and interdental PF. The data obtained was tabulated and subjected to statistical analysis. Spearman's correlation analysis test was performed to find the correlation of GT with GW, PD, and PF. Positive correlation was found between GT and GW ( r = 0.241). No significant correlation could be found between GT and PD; and between GT and PF. The present study confirmed a positive correlation between GT and GW. A weak negative correlation was found between GT and PD.

    Full Text Available Introduction: Dental plaque is a well-known etiologic factor for gingivitis. Ayurvedic drugs have been used since ancient times to treat diseases including periodontal diseases. Toothpastes made from herbal medicines are used in periodontal therapy to control bleeding and reduce inflammation. Aim: To compare the effectiveness of herbal and nonherbal fluoridated toothpaste on plaque and gingivitis among residents of ladies hostel in Mathura City. Materials and Methods: A randomized controlled clinical trial was carried out on 60 participants aged 18-30 years residing in a ladies hostel of Mathura City. The 60 participants were randomly allocated into two groups: Group-I: Experimental group using herbal toothpaste, Group-II: Control group using fluoridated toothpaste. The subjects were asked to brush twice daily with the assigned dentifrice using standardized brushing technique for 46 days. The plaque and gingival indices were recorded according to Silness and Loe (1964 and Loe and Silness (1963, respectively. These parameters were assessed at baseline, 3 weeks, and 6 weeks. Data were analyzed by Student paired t-test and unpaired t-test using Statistical Package for the Social Sciences version 21 manufactured by IBM Corporation - Armonk, New York, US. Results: Baseline plaque and gingival scores were found 1.02 ± 0.02 and 0.88 ± 0.06 for the experimental group and 1.02 ± 0.03 and 0.81 ± 0.08 for control group, respectively. After 6 weeks plaque and gingival scores were found 0.77 ± 0.07 and 0.72 ± 0.08 for experimental group and 0.78 ± 0.07 and 0.73 ± 0.11 for control group, respectively. Statistically significant differences were obtained before and after intervention in both groups (P ≤ 0.05. Conclusion: The herbal toothpaste was as effective as the conventionally formulated fluoride dentifrice in controlling plaque and gingivitis.

    Snap-On Smile (DenMat) appliances are tooth-borne overdentures used for a variety of temporary esthetic applications. However, their benefit can be limited in patients with high smile lines and altered gingival architecture because the teeth look too large. In this report, the author shows the chairside application of a silicone denture reline material used to recreate gingival anatomy on an overdenture fabricated from crystallized acetyl resin, the material used in a Snap-On Smile appliance. The author shows the gingival application's durability of greater than 2 years in a 78-year-old patient with multiple missing teeth and a severe mandibular ridge deformity. The author tested several commonly available denture reline materials and their bonding agents, which are known to bond to acrylic resin but have not been shown to bond to crystallized acetyl resin. The author observed no candida colonization during the 2-year reporting period. The author presents a simple and durable chairside technique to reproduce gingival tissue esthetically on Snap-On Smile appliances. Copyright © 2017 American Dental Association.

    Full Text Available Purpose: To study the management and outcomes of patients with paintball injuries resulting in traumatic glaucoma. Methods: A retrospective review was performed, identifying four patients with a confirmed diagnosis of traumatic glaucoma secondary to paintball sports. Results: Four male patients with paintball gun injuries presented with a mean follow-up time of 51 months after the date of injury. The mean age was 23.5 ± 18.6 years. Three patients presented with blunt trauma, while one patient had a ruptured globe. Presenting visual acuity (VA was hand motions in three of the patients and no light perception in the fourth patient. All patients were diagnosed with traumatic glaucoma and treated with glaucoma medications during their follow-up. Two patients received tube shunts to control intraocular pressures (IOPs. At the time of most recent follow-up, three patients had elevated IOPs and were not on any medications. VA at the last follow-up was 20/400 or worse. Conclusions: Traumatic glaucoma can be managed with surgical and medical interventions, while VA usually does not return to baseline levels prior to the injury. Prognostic predictors can be used to guide treatment and identify patients who should be closely followed. Because the presentation and onset is widely variable, follow-up and screening is crucial even years after the injury. Keywords: Paintball, Ocular trauma, Glaucoma, Secondary glaucoma

    We have begun to apply arterial redistribution and preoperative embolization in superselective intra-arterial chemotherapy from the superficial temporal artery. This study examines two typical cases of upper gingival cancer. Case 1 was a male, age 61, with T4N0M0 upper gingival cancer. Drug dosage began with 50-100 mg/m 2 /day of 5-fluorouracil (FU), while 15 mg/m 2 /hour of Docetaxel was also given once a week for three weeks. At the same time, radiation therapy with a total of 30 Gy (2 Gy at a time) was given. Immediately before the operation, embolization in the internal maxillary artery was performed in order to limit bleeding. Case 2 was a female, age 73, with T3N0M0 upper gingival cancer. This patient was also given 5-FU and Docetaxel for four weeks respectively with a total of 40 Gy radiation therapy. No operation was performed. Both cases gained complete response (CR) with a sole side effect of grade 3 mucositis. Superselective intra-arterial chemotherapy with arterial redistribution in the oral area is highly effective due to local, concentrated dosage of anticancer drug and reduced side effects. It is a promising method to replace surgical operation especially in cases of upper gingival cancer, whose tumor is often limited to the internal maxillary artery alone. (author)

    Full Text Available Background: Periodontal disease is a chronic, multi-factorial disease. Chronic periodontitis is one of the main causes of tooth loss. Chronic periodontitis is usually caused by Porphyromonas gingivalis (P. gingivalis. P. gingivalis can induce NFκB activation resulting in the increasing of periodontal extracellular matrix degradation. Curcumin can inhibit NFκB activation and reduce the severity of periodontal degradation. Purpose: This research was aimed to observe level of NFκB in gingival junctional epithelium of rat exposed to Porphyromonas gingivalis with local administration of curcumin. Methods: Sixteen Wistar rat were divided into two groups. Group 1 (treatment consisted of eight rat given 2 x 106CFU/ml P. gingivalis and 1% curcumin. Meanwhile, group 2 (control consisted of eight rat given 2 x 106 CFU/ml P. gingivalis only. GCF samples were collected from gingival sulcus. The samples were biochemically analyzed with ELISA method. Data were then analyzed statistically by using independent t-test (α=0.05. Results: The examination of NFκB level showed that there was significant difference between treatment group and control group (p<0.05. The level of NFκB in the treatment group was significantly lower than the control group. Conclusion: It can be concluded that 1% curcumin application can reduce NFκB level in gingival junctional epithelium of rat exposed to P. gingivalis.

    Laboratory animals are still necessary in scientific investigation and vaccine testing, but while novel methodological approaches are not available for their replacement, the search for new, humane, easy, and painless methods is necessary to diminish their stress and pain. When multiple blood samples are to be collected from hamsters and guinea pigs, the number of available venipuncture sites-which are greatly diminished in these species in comparison with other rodents due to the absence of a long tail-, harasses animal caregivers and researchers. Thus, this study aimed to evaluate if gingival vein puncture could be used as an additional route to obtain multiple blood samples from anesthetized hamsters and guinea pigs in such a way that animal behavior, well-being or hematological parameters would not be altered. Thus, twelve anesthetized Syrian golden hamsters and English guinea pigs were randomly allocated in two groups: a control group, whose blood samples were not collected, and an experimental group in which blood samples (200 microliters) were collected by gingival vein puncture at weekly intervals over six weeks. Clinical assessment, body weight gain and complete blood cell count were evaluated weekly, and control and experimental animals were euthanized at week seven, when the mentolabial region was processed to histological analyses. Multiple blood sampling from the gingival vein evoked no clinical manifestations or alteration in the behavioral repertoire, nor a statistically significant difference in weight gain in both species. Guinea pigs showed no alteration in red blood cell, leukocyte or platelet parameters over time. Hamsters developed a characteristic pattern of age-related physiological changes, which were considered normal. Histological analyses showed no difference in morphological structures in the interdental gingiva, confirming that multiple blood sampling is barely traumatic. Thus, these results evidence that blood collection from multiple

    2016-01-01

    Full Text Available Antiphospholipid antibody (APLA syndrome is a noninflammatory autoimmune disease, with innumerable clinical manifestations ranging from recurrent thrombosis and pregnancy morbidity to valvular lesions, transverse myelitis, thrombocytopenia, and hemolytic anemia. APLAs in antiphospholipid syndrome (APS are well-known risk factors for cerebrovascular accidents. Stroke is the most common manifestation of APS in the central nervous system. Gingival enlargement is a known side effect of phenytoin which is an antiepileptic drug. This can have a significant effect on the quality of life as well as increasing the oral bacterial load by generating plaque retention sites. The management of gingival overgrowth seems to be directed at controlling gingival inflammation through a good oral hygiene regimen. Thus, this case report aims to describe the conservative management of phenytoin-induced gingival enlargement combined with inflammatory enlargement in a patient with APLA syndrome.

The gel contains the essential oils menthol and thymol and the antioxidants ferulic acid and phloretin. Thirty patients from the university's orthodontic clinic were screened for gingivitis and randomly allocated into treatment and placebo-control groups. Each patient was evaluated at three orthodontic treatment visits (T1, T2, and T3). A periodontal examination, including probing depth (PD), bleeding on probing (BOP), gingival index (GI), and plaque index (PI) was performed at each visit. Between T1 and T2, patients were instructed to apply a topical gel (active or placebo) to their gingiva twice daily after brushing. From T2 to T3, patients were instructed to discontinue use of the gel. The treatment group showed statistically significant (P gingivitis.

    Idiopathic gingival enlargement is a rare condition characterized by massive enlargement of the gingiva. It may be associated with other diseases/conditions characterizing a syndrome, but rarely associated with periodontitis. This case report describes an unusual clinical form of gingival enlargement associated with chronic periodontitis. Clinical examination revealed diffuse gingival enlargement. The lesion was asymptomatic, firm, and pinkish red. Generalized periodontal pockets were observed. Radiographic evaluation revealed generalized severe alveolar bone loss. Histopathological investigations revealed atrophic epithelium with dense fibrocollagenous tissue. Lesions healed successfully following extraction and surgical excision, and no recurrence was observed after 1 year follow-up but recurrence was observed at 3 and 5-years follow-up. Successful treatment of idiopathic gingival enlargement depends on proper identification of etiologic factors and improving esthetics and function through surgical excision of the over growth. However, there may be recurrence.

    The purpose of this study was to evaluate chlorhexidine to control gingivitis and Candida species (spp.) in children infected with the human immunodeficiency virus (HIV) and their acceptance of the therapy. Twenty-six HIV+ children were selected, and oral exam-established biofilm, gingival indexes, and stimulated saliva were collected for Candida ssp. identification. The children brushed their teeth for 21 days with chlorhexidine gel (0.2%). Salivary samples, biofilm, and gingival indexes were collected after 21-days and again 35 days after ceasing gel use. The children answered a questionnaire about the therapy. All children tested positive for Candida and gingivitis. After 21 days, Candida counts and gingivitis decreased in 25 and 26 children, respectively. Mean reduction was approximately 68% for Candida spp. and 74% for gingivitis. Thirty-five days after discontinuing gel use, gingivitis and Candida spp. increased in 13 and 16 patients, respectively. Considering the Candida spp., the heavy growth was lower in the first re-evaluation. Candida albicans was the most frequent species. Approximately 85% did not experience inconvenience with the gel, and approximately 48% thought it was good for tooth-brushing. Chlorhexidine therapy may be an option to treat and pre- vent gingivitis and reduce yeast counts in children infected with HIV.

    An antiplaque agent with minimal side effects that can be used as an effective adjunct to mechanical plaque control is needed. The current study is designed to evaluate efficacy of triphala (TRP) mouthwash in reduction of plaque and gingivitis. Ninety individuals with chronic generalized gingivitis were randomly assigned to three groups: 1) group I, placebo mouthwash; 2) group II, TRP mouthwash; and 3) group III, chlorhexidine (CHX) mouthwash. All individuals were instructed to rinse with their respective mouthwash twice daily. 1) Plaque index (PI); 2) gingival index (GI); 3) oral hygiene index-simplified (OHI-S); and 4) microbiologic colony counts were recorded at baseline and at 7, 30, and 60 days. All three groups showed gradual reduction in PI, GI, and OHI-S levels from baseline to 7, 30, and 60 days. There was also significant reduction in microbial counts in all groups at all time intervals except in group I. A significant difference was noticed with respect to reduction in PI, GI, OHI-S, and microbiologic counts in group I compared with groups II and III. However, no significant differences were found between groups II and III for any parameters at any time intervals. TRP mouthwash was found to decrease inflammatory parameters from baseline to follow-up intervals. Because improvement in gingivitis was comparable with that of CHX mouthwash, TRP mouthwash can be considered a potential therapeutic agent in the treatment of gingivitis.

    Full Text Available Background/Aim. Gingival recession progression in clinical practaice has influenced the development of various surgical procedures and techniques for solving esthetic imperfections and subjective difficulties coused by gingival recession. The aim of this study was to verify efficacy of surgical procedures and to compare both of surgical procedures through the keratinized tissue width. Methods. The study included 20 teeth with gingival recesion, Müller class I and II. Ten teeth with gingival recession were treated with connective tissue autotransplants with periosteum in combination with coronary guided surgical flap (CTG group. On the contralateral side 10 teeth with gingival recession were treated with the same surgical procedures but in combination with platelet-rich plasma (CTGPRP group. We measured the keratinized tissue width. For statistical significance we used the Student's t-test. Results. The study reveled a statistical significance in reducing vertical deepress of recession by both used treatments. Root deepness in CTG and CTG-PRP group was 90% and 93.5%, respectively. With both surgical techniques we achieved larger zone of keratinized gingiva but with a wide zone of keratinized tissue in CTG - the PRP group. Conclusion. The concept regeneration technique with PRP and with the stimulating influence of platele activated growth factors results in the regeneration of deep periodontal tissue as an important prerequisite for the successful treatment of gingival recession.

    Violence, a serious public health problem in Thailand, remains largely unknown for its economic costs. This study is a national-level economic cost-estimates of injury from interpersonal and self-directed violence for Thailand during 2005 using the World Health Organization-US Centers for Disease Control and Prevention's guidelines. Direct medical costs from self-directed violence totaled 569 million Baht (THB) while the cost of interpersonal violence was THB 1.3 billion. Productivity losses for injuries due to self-directed violence were estimated at THB 12.2 billion and those for interpersonal violence were THB 14.4 billion. The total direct medical cost, thus, accounted for about 4% of Thailand's total health budget while the productivity losses accounted for approximately 0.4% of Thailand s GDP In summary, interpersonal and self-directed violence caused a total loss of 33.8 billion baht for Thailand in 2005. More than 90% of the economic loss was incurred from productivity loss and about four-fifths came from men.

    To evaluate the correlation between dental plaque formation and gingival health in subjects performing high oral hygiene standards over short or extended intervals. Fifty-two non-dental students volunteered for this study. The subjects, trained to perform high oral hygiene standards, were randomized to perform oral hygiene at 12-, 24-, 48-, or 72-h interval over 30 days. The plaque index (PlI) and the gingival index (GI) were evaluated at baseline, 15, and 30 days. For the statistical analysis, oral hygiene intervals were collapsed into daily (12 and 24 h; G12/24) and extended (48 and 72 h; G48/72) intervals. Summary statistics (mean ± SD) and Spearman correlations between the PlI and the GI at baseline, 15, and 30 days were estimated. At baseline, correlation coefficients between PlI and GI were positive for both groups (r = 0.29 and r = 0.25). At day 15 and 30, correlation was maintained with similar baseline values for the G48/72 group. GI levels did not increase despite an increase in PlI for the G12/24 group, and the correlation was lower than that observed at baseline (r = 0.13 vs. r = 0.29). In subjects with high oral hygiene standards, the oral hygiene frequency governs the correlation between dental plaque formation and gingival health. Subjects performing high oral hygiene standards at daily intervals will maintain gingival health in difference to subjects using extended hygiene intervals. Subjects performing high oral hygiene standards at daily intervals will maintain gingival health in difference to subjects using extended hygiene intervals.

    Full Text Available Background: Gingival overgrowth is a common side-effect of amlodipine regimen on the oral cavity. There is controversy regarding the cause and effect relationship of periodontal health and drug induced gingival overgrowth. Therefore, this study was conducted to investigate and to assess the relationship between the periodontal health and the onset and severity of gingival overgrowth in hypertensive patients receiving amlodipine. Materials and Methods: A total of 99 known hypertensive patients on amlodipine regimen were included in this study. Probing pocket depth (PPD and clinical attachment loss (CAL were noted on four sites of maxillary and mandibular anterior teeth. Gingival enlargement scores were assessed for each patient by employing the hyperplastic index. Oral hygiene status was evaluated using the calculus index (CI. Patients were divided into H, E and L groups based on their periodontal status and responders and non-responders based on their hyperplastic index scores. Differences in means of different periodontal variables in different groups were tested for significance by using ANOVA and unpaired Student t-test. Pearson′s correlation coefficient was calculated to assess the correlation between different variables. For all analyses, P < 0.05 was considered to be significant. Results: All the periodontal parameters were statistically highly significant (P = 0.00 amongst H, E and L groups and between responders and non-responders. Statistically highly significant Pearson correlation coefficients were found between mean PPD and mean hyperplastic score, mean CAL and mean hyperplastic score and mean calculus and mean hyperplastic score. Conclusion: The results of this study indicated a definite association between periodontal health and development and severity of amlodipine-induced gingival overgrowth

    2015-04-01

    Based on evidence as presented in systematic reviews what is the efficacy and safety of available homecare toothbrush regimens for mechanical plaque removal on plaque and gingivitis in adults? Three Internet sources were used (up to and including August 2014) to search for appropriate papers that satisfied the study purpose. Plaque scores and gingivitis scores were considered to be the primary parameter of interest. Safety was considered an important facet in relation to efficacy. Data and conclusions as presented in the selected papers were extracted. The potential risk of bias was estimated and the emerging evidence was graded. Independent screening of 176 unique reviews resulted in 10 published and eligible systematic reviews. They were categorized into one review evaluating the effect of an oral hygiene instruction with a toothbrush on plaque and gingivitis scores, five evaluating the efficacy of manual and power toothbrushes and three reviews evaluating toothbrush safety and one evaluating toothbrush contamination. Tooth brushing is effective in reducing levels of dental plaque. With respect to gingivitis power toothbrushes have a benefit over manual toothbrushes. The greatest body of evidence was available for oscillating-rotating brushes. Tooth brushing generally can be considered safe for the teeth and their investing tissues. © 2015 John Wiley & Sons A/S.

    The emergence profile concept of an implant restoration is one of the most important factors for the esthetics and health of peri-implant soft tissue. This paper reports on two cases of gingival recontouring by the fabrication of a provisional implant restoration to produce an optimal emergence profile of a definitive implant restoration. After the second surgery, a preliminary impression was taken to make a soft tissue working cast. A provisional crown was fabricated on the model. The soft tissue around the implant fixture on the model was trimmed with a laboratory scalpel to produce the scalloped gingival form. Light curing composite resin was added to fill the space between the provisional crown base and trimmed gingiva. After 4 to 6 weeks, the final impression was taken to make a definitive implant restoration, where the soft tissue and tooth form were in harmony with the adjacent tooth. At the first insertion of the provisional restoration, gum bleaching revealed gingival pressure. Four to six weeks after placing the provisional restoration, the gum reformed with harmony between the peri-implant gingiva and adjacent dentition. Gingival recontouring with a provisional implant restoration is a non-surgical and non-procedure-sensitive method. The implant restoration with the optimal emergence profile is expected to provide superior esthetic and functional results.

    Full Text Available Gingival inflammation is the physiological response to poor oral hygiene. If gingivitis is not resolved the response will become an established lesion.We studied whether gingivitis associates with elevated risk for stroke. The hypothesis was based on the periodontitis-atherosclerosis paradigm.In our prospective cohort study from Sweden 1676 randomly selected subjects were followed up from 1985 to 2012. All subjects underwent clinical oral examination and answered a questionnaire assessing background variables such as socio-economic status and pack-years of smoking. Cases with stroke were recorded from the Center of Epidemiology, Swedish National Board of Health and Welfare, Sweden, and classified according to the WHO International Classification of Diseases. Unpaired t-test, chi-square tests, and multiple logistic regression analyses were used.Of the 1676 participants, 39 subjects (2.3% had been diagnosed with stroke. There were significant differences between the patients with stroke and subjects without in pack-years of smoking (p = 0.01, prevalence of gingival inflammation (GI (p = 0.03, and dental calculus (p = 0.017. In a multiple regression analysis the association between GI, confounders and stroke, GI showed odds ratio 2.20 (95% confidence interval 1.02-4.74 for stroke.Our present findings showed that gingival inflammation clearly associated with stroke in this 26-year cohort study. The results emphasize the role of oral health personnel in prevention.

    Full Text Available Background: Idiopathic gingival enlargement is a rare condition characterized by massive enlargement of the gingiva. It may be associated with other diseases/conditions characterizing a syndrome, but rarely associated with periodontitis. Case Description: This case report describes an unusual clinical form of gingival enlargement associated with chronic periodontitis. Clinical examination revealed diffuse gingival enlargement. The lesion was asymptomatic, firm, and pinkish red. Generalized periodontal pockets were observed. Radiographic evaluation revealed generalized severe alveolar bone loss. Histopathological investigations revealed atrophic epithelium with dense fibrocollagenous tissue. Lesions healed successfully following extraction and surgical excision, and no recurrence was observed after 1 year follow-up but recurrence was observed at 3 and 5-years follow-up. Clinical Implications: Successful treatment of idiopathic gingival enlargement depends on proper identification of etiologic factors and improving esthetics and function through surgical excision of the over growth. However, there may be recurrence.

    Full Text Available ABSTRACTOBJECTIVE: To evaluate the influence of oral supplementation with arginine on regeneration of injuries due to straining of the anterior tibial muscle of rats. METHODS: Twenty-four Wistar rats of weight 492.5 ± 50.45 g were used. Injuries were induced through straining the anterior tibial muscles. The rats were separated into three groups of eight rats each. In the untreated group (UTG, after induction of injuries, the rats were observed for 24 h. In the simulation group (SG and the arginine group (AG respectively, the rats received isotonic saline solution and arginine solution via direct gavage, over a seven-day period. At the end of the period, blood samples were collected for serum evaluations of creatine kinase (CK, lactic dehydrogenase (LDH, aspartate aminotransferase (AST and C-reactive protein (CRP. The right and left anterior tibial muscles were resected for histopathological evaluations on the muscle injuries, investigating edema, hemorrhage and disorganization or morphometric alteration of the muscle fibers. The tissue repair was investigated in terms of proliferation of adipose tissue, angiogenesis and collagen fibers. The ANOVA and Student's tmethods were used and p≤ 0.05 was taken to be statistically significant. RESULTS: In the serum evaluations, the AG showed lower CK assay values and higher AST values. In the histopathological evaluation, the UTG presented edema and hemorrhage compatible with injuries due to strain; the SG presented edema and hemorrhage with proliferation of adipose tissue and collagen fibers; and the AG presented not only the findings of the SG but also, especially, intense angiogenesis. CONCLUSION: Oral supplementation with arginine did not cause any significant metabolic alterations that would contraindicate its use and it induced angiogenesis during the repair of muscles injured due to strain.

    2012-01-01

    Full Text Available Smile expresses a feeling of joy, success, sensuality, affection, and courtesy, and reveals self-confidence and kindness. The harmony of the smile is determined not only by the shape, the position, and the color of the teeth, but also by the gingival tissues. Although melanin pigmentation of the gingiva is completely benign and does not present a medical problem, complaints of "black gums" are common, particularly in patients having a very high smile line. Thus, perio-esthetic treatment modalities strive to achieve a harmonious inter-relationship of the pink with white, which is imperative of all treatment procedures. For depigmentation of gingival, different treatment modalities have been reported, such as bur abrasion, scraping, partial thickness flap, cryotherapy, electrosurgery, and laser. In the present case series, scraping, electrosurgery, and diode laser have been tried for depigmentation, which are simple, effective, and yield good results, along with good patient satisfaction.

  10. Analysis of gingival pocket microflora and biochemical blood parameters in dogs suffering from periodontal disease.

    2014-01-01

    Periodontal diseases in dogs are caused by bacteria colonising the oral cavity. The presence of plaque comprising accumulations of aerobic and anaerobic bacteria leads to the development of periodontitis. Due to the fact that in a large percentage of cases periodontal diseases remain undiagnosed, and consequently untreated, they tend to acquire a chronic character, lead to bacteraemia and negatively impact the health of internal organs. The aim of the present study was to perform a qualitative microbiological analysis of gingival pockets and determine the correlations between selected morphological and biochemical blood parameters and the extent periodontal diseases. Twenty-one dogs treated for periodontal diseases were qualified for the study and subsequently divided into two groups: with 3rd and 4th stage of periodontal disease. Swabs from the patients' gingival pockets were taken for bacteriological testing. Blood was tested for parameters including erythrocyte count, haemoglobin concentration, haematocrit values and leukocyte count. Blood serum was analyzed with respect to the concentrations of alanine transaminase (ALT), aspartate transaminase (AspAT/AST) and urea. The microbiological analysis of gingival pockets indicated the presence of numerous pathogens with a growth tendency in bacterial cultures observed in dogs with advanced-stage periodontal disease. The concentration of biochemical blood markers was significantly higher in dogs with 4th stage of periodontal disease, to compared to the 3rd-stage group. Morphological parameters were not significantly different with the exception of haemoglobin concentration, which was lower in dogs with 4th stage disease. In both groups, elevated leukocyte counts were observed. By conducting a detailed microbiological examination, it is possible to provide a better prognosis, plan adequate treatment and monitor dogs treated for peridontopathy.

    Patil, Veena A; Desai, Manthan H

    2013-03-01

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

    Full Text Available BACKGROUND: Gingival hyperpigmentation is a common esthetical concern in patients with gummy smile or excessive gingival display. Laser ablation has been recognized recently as the most effective, pleasant and reliable technique. It has the advantage of easy handling, short treatment time, hemostasis, decontamination, and sterilization effect. AIM: In the present study we wanted to explore the efficacy of a 980 nm wavelength diode laser in gingival depigmentation clinically by using both VAS and digital imaging method as means of assessment. METHODS: Diode laser ablation was done for 15 patients who requested cosmetic therapy for melanin pigmented gums. The laser beam delivered by fiberoptic with a diameter of 320 µm, the diode laser system has 980 nm wave lengths and 3 W irradiation powers, in a continuous contact mode in all cases, the entire surface of each pigmented maxillary and mandibular gingiva that required treatment was irradiated in a single session. Clinical examination and digital image analysis were done and the patients were followed up for 3 successive months. RESULTS: There was a statistically significant change in prevalence of bleeding after treatment, as none of the cases showed any signs of bleeding 1 week, 1 month and 3 months after ablation. No statistically significant change was observed in the prevalence of swelling after treatment The VAS evaluation demonstrated that only 4 patients complained of mild pain immediately after the procedure. No pain was perceived from the patients in the rest of the follow up period. There was no statistically significant change in prevalence of pain immediately after treatment compared to pain during treatment. There was a decrease in cases with mild pain after 1 week, 1 month as well as 3 months compared to pain during treatment and immediately after treatment. CONCLUSION: Within the limitations of this study, the use of diode laser was shown to be a safe and effective treatment

    Calendula officinalis (C. officinalis), commonly known as pot marigold, is a medicinal herb with excellent antimicrobial, wound healing, and anti-inflammatory activity. To evaluate the efficacy of C. officinalis in reducing dental plaque and gingival inflammation. Two hundred and forty patients within the age group of 20-40 years were enrolled in this study with their informed consent. Patients having gingivitis (probing depth (PD) ≤3 mm), with a complaint of bleeding gums were included in this study. Patients with periodontitis PD ≥ 4 mm, desquamative gingivitis, acute necrotizing ulcerative gingivitis (ANUG), smokers under antibiotic coverage, and any other history of systemic diseases or conditions, including pregnancy, were excluded from the study. The subjects were randomly assigned into two groups - test group (n = 120) and control group (n = 120). All the test group patients were advised to dilute 2 ml of tincture of calendula with 6 ml of distilled water and rinse their mouths once in the morning and once in the evening for six months. Similarly, the control group patients were advised to use 8 ml distilled water (placebo) as control mouthwash and rinse mouth twice daily for six months. Clinical parameters like the plaque index (PI), gingival index (GI), sulcus bleeding index (SBI), and oral hygiene index-simplified (OHI-S) were recorded at baseline (first visit), third month (second visit), and sixth month (third visit) by the same operator, to rule out variable results. During the second visit, after recording the clinical parameters, each patient was subjected to undergo a thorough scaling procedure. Patients were instructed to carry out regular routine oral hygiene maintenance without any reinforcement in it. In the absence of scaling (that is, between the first and second visit), the test group showed a statistically significant reduction in the scores of PI, GI, SBI (except OHI-S) (P < 0.05), whereas, the control group showed no reduction in

    Full Text Available No systematic review has been published on the use of acupuncture for the treatment of chronic urinary retention (CUR due to spinal cord injury (SCI. The aim of this review was to assess the effectiveness and safety of acupuncture for CUR due to SCI. Three randomized controlled trials (RCTs including 334 patients with CUR due to SCI were included. Meta-analysis showed that acupuncture plus rehabilitation training was much better than rehabilitation training alone in decreasing postvoid residual (PVR urine volume (MD −109.44, 95% CI −156.53 to −62.35. Likewise, a combination of acupuncture and aseptic intermittent catheterization was better than aseptic intermittent catheterization alone in improving response rates (RR 1.23, 95% CI 1.10 to 1.38. No severe adverse events were reported. In conclusion, acupuncture as a complementary therapy may have a potential effect in CUR due to SCI in decreasing PVR and improving bladder voiding. Additionally, acupuncture may be safe in treating CUR caused by SCI. However, due to the lack of high quality RCTs, we could not draw any definitive conclusions. More well-designed RCTs are needed to provide strong evidence.

    In this study, we aimed to assess the effect of the duration of fixed orthodontic treatment on gingival enlargement (GE) in adolescents and young adults. The sample consisted of 260 subjects (ages, 10-30 years) divided into 4 groups: patients with no fixed orthodontic appliances (G0) and patients undergoing orthodontic treatment for 1 year (G1), 2 years (G2), or 3 years (G3). Participants completed a structured questionnaire on sociodemographic characteristics and oral hygiene habits. Clinical examinations were conducted by a calibrated examiner and included the plaque index, the gingival index, and the Seymour index. Poisson regression models were used to assess the association between group and GE. We observed increasing means of plaque, gingivitis, and GE in G0, G1, and G2. No significant differences were observed between G2 and G3. Adjusted Poisson regression analysis showed that patients undergoing orthodontic treatment had a 20 to 28-fold increased risk for GE than did those without orthodontic appliances (G1, rate ratio [RR] = 20.2, 95% CI = 9.0-45.3; G2, RR = 27.0, 95% CI = 12.1-60.3; G3 = 28.1; 95% CI = 12.6-62.5). The duration of orthodontic treatment significantly influenced the occurrence of GE. Oral hygiene instructions and motivational activities should target adolescents and young adults undergoing orthodontic treatment. Copyright © 2017 American Association of Orthodontists.

    To investigate the effects of an egg yolk-derived immunoglobulin (IgY) specific to Prevotella intermedia in vitro and in vivo. An IgY specific to P. intermedia was produced by immunizing hens with formaldehyde-inactivated P. intermedia and showed high titres when subjected to an ELISA. The obtained IgY inhibited the growth of P. intermedia in a dose-dependent manner at concentrations from 1 to 20 mg ml(-1) in Center for Disease Control and Prevention liquid medium. Forty rats were challenged with P. intermedia on gingivae and then randomly divided into four groups, which were syringed respectively with phosphate-buffered saline, 1 mg ml(-1) of tinidazole, 20 mg ml(-1) of nonspecific IgY and 20 mg ml(-1) of the IgY specific to P. intermedia at a dosage of 300 μl per day. Gingival index (GI), plaque index (PI), bleeding on probing (BOP), counts of white blood cell (WBC) and histopathological slide of the gums were measured after treatment for 15 days. The gingivitis rats treated with the IgY specific to P. intermedia showed significantly decreased GI, PI, BOP and WBC (P intermedia-mediated gingivitis. A new immunoglobulin specific to P. intermedia was developed from egg yolk. This specific IgY can dose-dependently inhibit the growth of P. intermedia and protect rats from gingivitis induced by P. intermedia. The new IgY has potential for the treatment of P. intermedia-mediated gingivitis. © 2013 The Society for Applied Microbiology.

    Chronic periodontitis and gingivitis are associated with various diseases; however, their impact on dementia is yet to be elucidated. This study is aimed at investigating the association between chronic periodontitis and gingivitis, and the risk of developing dementia. A total of 2,207 patients, with newly diagnosed chronic periodontitis and gingivitis between January 1, 2000 and December 31, 2000, were selected from the National Health Insurance Research Database of Taiwan, along with 6,621 controls matched for sex and age. After adjusting for confounding factors, Cox proportional hazards analysis was used to compare the risk of developing dementia during the 10-year follow-up period. Of the study subjects, 25 (1.13%) developed dementia compared to 61 (0.92%) in the control group. Cox proportional hazards regression analysis revealed that the study subjects were more likely to develop dementia (hazard ratio (HR) 2.085, 95% CI 1.552-4.156, p gingivitis have a higher risk of developing dementia. However, further studies on other large or national data sets are required to support the current findings. © 2016 S. Karger AG, Basel.

    To identify the best available evidence for the effect of toothbrushing on the initiation and progression of gingival recession and non-carious cervical lesions (NCCLs). A protocol was developed for the questions: Does traumatic toothbrushing, compared to normal toothbrushing, lead to an increased prevalence of non-inflammatory gingival recession? [FQ1] and NCCLs? [FQ2]. The search covered four electronic databases. Bibliographies of review articles, relevant texts, World and European Workshops were screened. Hand searches were performed of the Journals of Clinical Periodontology, Periodontology, Periodontal Research and IADR abstracts. A meta-analysis included 159 subjects and showed that subjects who used MTBs (manual toothbrush) had greater gingival recession after 12 months when compared with those using PTBs (powered toothbrush). Thirteen cross-sectional studies identified the most frequent toothbrushing factors associated with gingival recession as being toothbrushing frequency, a horizontal or scrub toothbrushing method, bristle hardness, toothbrushing duration and the frequency of changing a toothbrush. The principal toothbrushing factors associated with NCCLs were toothbrushing method and frequency. The data to support or refute the association between toothbrushing and gingival recession and NCCLs remain largely inconclusive. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Background: A high number of patients with periodontitis may have undiagnosed diabetes. Self-monitoring devices provide a simple method for rapid monitoring of the glucose level in the blood by utilizing a blood sample from the finger, but this method requires a needle puncture to obtain blood. It is possible that gingival crevicular blood (GCB from routine periodontal probing may be a source of blood for glucose measurements. Aim: To establish whether GCB can be used as a non-invasive diagnostic aid in screening for diabetes mellitus during routine periodontal examination. Materials and Methods: The study involved 50 diabetics and 50 non-diabetics, with an age range of 26-66 years. Both diabetic and non-diabetic patients had moderate to severe gingivitis with at least one tooth in the maxillary anterior region showing bleeding upon probing. The Gingival Index and Oral Hygiene Index-Simplified were recorded. Blood oozing from the gingival sulcus/pocket following periodontal pocket probing was collected using a capillary tube and transferred to the test stick of a glucose self-monitoring device (Accu-Chek, Roche Diagnostic, Germany in patients with comparable gingival and oral hygiene status. This value was compared with the peripheral fingerstick blood glucose (PFBG value, which was obtained by pricking the finger tip at the same visit. Statistical analysis was performed using Pearson′s correlation coefficient. Result: There was no statistically significant difference between the gingival crevicular blood glucose (GCBG values and the PFBG values in both the diabetic (P = 0.129, NS and the non-diabetic (P = 0.503, NS groups. Karl Pearson′s product-moment correlation coefficient was calculated, which showed a positive correlation between the two measurements in the diabetic (r = 0.943 as well as the non-diabetic (r = 0.926 groups. Conclusion: The results suggest that GCB can be used as a non-invasive diagnostic aid in screening for diabetes

    To compare the anti-gingivitis effect of a power toothbrush relative to a manual toothbrush control. This was a 3-month, randomized and controlled, single-center, parallel group, examiner-blinded clinical study. 123 Chinese adults in good general health and with at least 15 gingival bleeding sites, as measured by the Gingival Bleeding Index, were enrolled into the study. At baseline, pre-treatment gingivitis levels were assessed using the Mazza Bleeding Index. Subjects were then randomly assigned to receive either an oscillating-rotating power toothbrush [Oral-B Professional Care 7000 (D17u/EB17)] or a flat-trim manual toothbrush with tapered filaments (Lion Dentor Systema). Subjects brushed at home twice-daily with their assigned toothbrush and a marketed sodium fluoride dentifrice (Crest Cavity Protection dentifrice), and were reevaluated at Months 1, 2, and 3. 113 evaluable subjects completed the study. Both groups showed significant reductions in gingivitis from baseline for all time points measured (Pgingivitis reductions of 7.11%, 9.20% and 8.47%, respectively, than the manual toothbrush (Pgingivitis compared with a manual toothbrush at Months 1, 2 and 3.

    To ascertain whether interdental cleaning behaviours of Australian adults were associated with lower levels of plaque, gingivitis and periodontal disease. Data were obtained from the National Survey of Adult Oral Health 2004-06. Outcome variables were three indicators of oral hygiene outcomes (the presence or not of dental plaque, dental calculus and gingivitis) and two of periodontal disease (the presence or not of at least one tooth with a periodontal pocket or clinical attachment loss of ≥ 4 mm). The independent variable was classified into the following three groups: regularly clean interproximally 'at least daily' (daily+); 'less than daily' (dental plaque (dental calculus (dental plaque and gingivitis, although there was no significant association between regular interdental cleaning and clinical attachment loss. © 2011 John Wiley & Sons A/S.

    Full Text Available 3- Dentist   Background and Aims: An attractive, well-balanced smile is a paramount treatment objective of the modern orthodontic therapy. The purpose of this study was to determine the effects of the buccal corridor size and tooth-gingival display on the smile esthetics as perceived by two groups of the students.   Materials and Methods: A colored image of a woman frontal posed smile was selected. The image was altered digitally to produce different buccal corridor sizes (6%, 12.5% and 20% and different tooth-gingival displays (maxillary central incisors and 2 mm of gingival, maxillary central incisors and dental papilla and 80% of the maxillary central incisors. The different buccal corridor sizes and tooth-gingival displays were combined to produce 9 images. These altered images were rated by 120 medical and dental students using Visual Analogue Scale (VAS. Data were analyzed using Mann-Whitney test, Pairwise comparison LSD test, Repeated measure MANOVA and ICC (Intraclass Correlation Coefficient.   Results: The smile which had the buccal corridor size of 12.5% and complete incisor display without gingival display received the highest rates among the nine smile images in the dental students group. But in the medical students group the smile with the buccal corridor size of 12.5% and 2 mm gingival display, received the highest rates among the nine smile images. There was no significant difference in judging between the male and female raters for the both groups (P>0.05. The dental students were more critical about the increasing of the gingival display.   Conclusion: In the treatment procedure that may lead to the combination of wide buccal corridor and more tooth-gingival show, more caution should be considered.

    Objective: To explore the clinical significance of changes of gingival crevicular fluid levels of interleukin-10 (IL-10), interleukin-18 (IL-18) and interferon-γ were determined with RIA in 42 patients with periodontitis both before and after trentment as well as in 30 controls. Results: Before treatment, the gingival crevicular fluid level of IL-18 and IFN-γ in the patients were significant higher than those in controls (P 0.05). After one month of treatment, the gingival crevigcular fluid levels of IL-18 and IFN-γ were markedly dropped, but remained significantly higher than those in controls (P<0.05). The gingival crevicular fluid levels of IL-10 were markedly dropped, but remained significantly higher than those in controls (P<0.05). The gingival crevicular fluid levels of IL-10 were significant higher than those in controls (P<0.01). The gingival fluid contents of IL-10 and IL-18 were positively correlated with the depth of periodontal pouch and looseness of attachment (r= 0.2617, r= 0.2802, P<0.05) but the interferon-γ contents were negatively correlated (r= -0.1743, P<0.05). Conclusion: The changes of gingival carvacrol fluid levels of interleukin-10, interleukin-18 and If-γ in patients with periodontics suggested that there were disturbances of immunomodulation.

    Periodontitis and gingivitis are one of the most infectious diseases in human. Several studies have been carried out on dependence of periodontitis and stroke. The aim of this study was to investigate the gingivitis and periodontitis as a risk factor for stroke in Iranian population. A case-control study was conducted on 100 patients suffering from stroke as case group, and 100 hospitalized patients as control group. The case group included 42 males and 58 females, and in control group there were 44 males and 56 females. Using a University of North Carolina-15 manual probe, the clinical attachment level, the distance between the cemento-enamel junction and the probed base of the periodontal pocket, were recorded by gingival and periodontal indexes. The data were analyzed by multiple logistic regressions, Chi-square test, Fisher's test, t-test, Man Whitney, and SPSS11.5 software program. P > 0.05 was considered as significant. The case group included 42 males and 58 females, and in control group 44 males and 56 females were included. In this investigation, the average of gingival index in men and women of case group was 1.22 ± 0.55 and 1.31 ± 0.55, respectively. This study showed that the average of gingival index in case group was more than control group. Periodontal index in both groups in men was more than women. The moderate and severe periodontitis in case group were more than that of control group (P = 0.003, P = 0.001). The result of this study shows that there is a significant relation between stroke and periodontal index; however, there isn't any significant relation between stroke and gingival index.

  8. Human dental pulp stem cells and gingival fibroblasts seeded into silk fibroin scaffolds have the same ability in attracting vessels

    2016-04-01

    Full Text Available Neovascularization is one of the most important processes during tissue repair and regeneration. Current healing approaches based on the use of biomaterials combined with stem cells in critical-size bone defects fail due to the insufficient implant vascularization and integration into the host tissues. Therefore, here we studied the attraction, ingrowth, and distribution of blood vessels from the chicken embryo chorioallantoic membrane into implanted silk fibroin scaffolds seeded with either human dental pulp stem cells or human gingival fibroblasts. Perfusion capacity was evaluated by non-invasive in vivo Magnetic Resonance Imaging while the number and density of blood vessels were measured by histomorphometry. Our results demonstrate that human dental pulp stem cells and gingival fibroblasts possess equal abilities in attracting vessels within silk fibroin scaffolds. Additionally, the prolonged in vitro pre-incubation period of these two cell populations favors the homogeneous distribution of vessels within silk fibroin scaffolds, which further improves implant survival and guarantees successful healing and regeneration.

    Full Text Available Introduction/Aim. Gingivitis is a common occurrence in children and may well be thought as a risk factor for the appearance and progression of the diseases of parodontal tissues. It is thus necessary to react in a timely and adequate fashion to prevent the disease to become serious and produce parodontopathy. The aim of the study was to establish the efficacy of hyaluronic acid in the treatment of chronic gingivitis in children. Methods. The study enrolled 130 children with permanent dentition. All of the examinees were divided into three groups: group I - 50 patients with chronic gingivitis in which only the basic treatment was applied; group II - 50 patients with chronic gingivitis in which hyaluronic acid was applied in addition to basic treatment; group III - 30 examinees with healthy gingiva (control group. Assessment of oral hygiene and status of the gingiva and parodontium was done using the appropriate indexes before and after the treatment. Inflammation of the gingiva was monitored by way of cytomorphometric studies. Results. The pretreatment values of the plaque index (PI were high: in the group I PI was 1.94; in the group II PI was 1.68. After the treatment, the PI value was reduced to null in both groups (PI = 0. In the group III PI was 0.17. The bleeding index (BI in the group I was 2.02 before and 0.32 after the treatment; the BI value in the group II was 1.74 before and 0.16 after the treatment. In the group III BI was 0. In the group I, the Community Periodontal Index of Treatment Needs (CPITN was 1.66 before and 0.32 after the treatment; in the group II, the CPITN value was 1.5 before and 0.24 after the treatment. In the group III, the CPITN value was 0. In the group I, the size of the nuclei of the stratified squamous epithelium of the gingiva was reduced, although not so much as the nuclear size in the group II of examinees. Conclusion. Basic treatment is able to successfully treat chronic gingivitis in children. The use of

    2015-06-01

    In this paper, we investigate the effect of substituting SrO for CaO in silicate and phosphate bioactive glasses on the human gingival fibroblast activity. In both materials the presence of SrO led to the formation of a CaP layer with partial Sr substitution for Ca. The layer at the surface of the silicate glass consisted of HAP whereas at the phosphate glasses it was close to the DCPD composition. In silicate glasses, SrO gave a faster initial dissolution and a thinner reaction layer probably allowing for a continuous ion release into the solution. In phosphate glasses, SrO decreased the dissolution process and gave a more strongly bonded reaction layer. Overall, the SrO-containing silicate glass led to a slight enhancement in the activity of the gingival fibroblasts cells when compared to the SrO-free reference glass, S53P4. The cell activity decreased up to 3 days of culturing for all phosphate glasses containing SrO. Whereas culturing together with the SrO-free phosphate glass led to complete cell death at 7 days. The glasses containing SrO showed rapid cell proliferation and growth between 7 and 14 days, reaching similar activity than glass S53P4. The addition of SrO in both silicate and phosphate glasses was assumed beneficial for proliferation and growth of human gingival fibroblasts due to Sr incorporation in the reaction layer at the glass surface and released in the cell culture medium.

    Many fibrotic processes are associated with an increased level of transforming growth factor-β1 (TGF-β1). TGF-β1 can increase synthesis of matrix proteins and enhance secretion of protease inhibitors, resulting in matrix accumulation. Connective tissue growth factor (CTGF) is a downstream profibrotic effector of TGF-β1 and is associated with the fibrosis in several human organs. Curcumin has been applied to reduce matrix accumulation in fibrotic diseases. This study was aimed to evaluate whether curcumin could suppress TGF-β1-induced CTGF expression and its related signaling pathway involving in this inhibitory action in primary human gingival fibroblasts. The differences in CTGF expression among three types of gingival overgrowth and normal gingival tissues were assessed by immunohistochemistry. Gingival fibroblast viability in cultured media with different concentrations of curcumin was studied by MTT assay. The effect of curcumin on TGF-β1-induced CTGF expression in primary human gingival fibroblasts was examined by immunoblotting. Moreover, the proteins involved in TGF-β1 signaling pathways including TGF-β1 receptors and Smad2 were also analyzed by immunoblotting. CTGF was highly expressed in fibroblasts, epithelial cells and some of endothelial cells, smooth muscle cells, and inflammatory cells in phenytoin-induced gingival overgrowth tissues rather than in those of hereditary and inflammatory gingival overgrowth tissues. Moreover, CTGF expression in the epithelial and connective tissue layers was higher in phenytoin-induced gingival overgrowth tissues than in normal gingival tissues. Curcumin was nontoxic and could reduce TGF-β1-induced CTGF expression by attenuating the phosphorylation and nuclear translocation of Smad2. Curcumin can suppress TGF-β1-induced CTGF expression through the interruption of Smad2 signaling. Copyright © 2018. Published by Elsevier B.V.

    In previous studies, toothpastes with high levels of sodium bicarbonate (>50%) have reduced gingival inflammation and oral malodour. This study compared the effects of brushing for 6 weeks with 67% (test group) or 0% (control group) sodium bicarbonate toothpaste on gingival health. This was a single-centre, single examiner-blind, randomized, controlled, two-treatment, parallel-group study. Eligible subjects (≥18 years) had ≥20 gradable teeth, mild-to-moderate gingivitis, a positive response to bleeding on brushing and ≥20 bleeding sites. The primary objective was to compare the number of bleeding sites following twice-daily use of 67% sodium bicarbonate toothpaste or 0% sodium bicarbonate toothpaste after 6 weeks. Secondary endpoints included Modified Gingival Index (MGI), Bleeding Index (BI) and volatile sulphur compounds (VSC), assessed after 6 weeks. Safety was assessed by treatment-emergent oral soft tissue abnormalities and adverse events. Of 148 patients randomized (74 to each treatment), 66 (89.2%) completed the study in the test group, compared with 69 (93.2%) in the control group. Compared with the control group, the test group had a significant reduction in the number of bleeding sites at Week 6 (absolute difference - 11.0 [-14.0, -8.0], P < 0.0001; relative difference - 25.4%), together with significant reductions in MGI and BI (both P < 0.0001). Although the median reductions from baseline for VSC were numerically greater in the test group, the difference did not reach statistical significance (P = 0.9701). This 67% sodium bicarbonate toothpaste provided statistically significant improvements in gingival health and bleeding after 6 weeks of use. © 2016 The Authors.

    Vulvovaginal-gingival lichen planus (VVG-LP) consists of a triad of symptoms: vulval, vaginal and gingival lichen planus lesions. The aim of this study was to analyse the prevalence of lesions in various anatomical locations in patients with VVG-LP. The study included 126 consecutive patients with lichen planus. Sixteen (12.7%) patients fulfilled the criteria of VVG-LP. In 12/16 (75%) patients with VVG-LP scalp lesions were also observed. Stratified epithelium-specific antinuclear antibodies (SES-ANA) and anti-ΔNp.3α antibodies were detected in 10/16 (75%) patients with VVG-LP and in 15/110 (13.6%) patients with other forms of lichen planus (p lichen planopilaris. The new entity may be termed "vulvovaginal-gingival-pilar lichen planus" and our study indicates that SES-ANA is a marker of this type of lichen planus with extensive, severe and refractory-to-therapy involvement of the mucous membranes, skin and scalp.

    Full Text Available Background: In dentistry, esthetics has a special place. Although gingival melanin pigmentation does not present a medical problem, clinicians are often faced with a challenge of achieving gingival esthetics. Materials and Methods: A method of de-epithelialization of the pigmented gingiva using Kirkland′s gingivectomy knife is described. Twenty patients who were conscious about their gingival melanin pigmentation were selected. The gingiva of the whole of the arch was abraded until the entire visible pigmentation was removed. Clinical observations for intensity of pigmentation were recorded at baseline and then after surgery at monthly intervals over a period of 9 months according to Dummett-Gupta Oral Pigmentation Index scoring criteria proposed by Dummett C. O. in 1964. Results: The mean gingival melanin pigmentation score came down to 0.407 after 9 months as compared to preoperative score, which was 2.24. No repigmentation occurred in fair-complexioned persons. In persons with wheatish complexion, repigmentation was seen in 85.71% of the cases, but scores came down to 0.38 postoperatively as compared to 2.27 preoperatively. In dark complexioned persons, repigmentation occurred in all cases, but the mean scores were 0.93 as compared to 2.40 preoperatively. The difference between preoperative and postoperative mean scores for each segment was put to statistical analysis by applying paired t test and was found to be significant. Conclusion: As this method has shown statistically significant results, it can be used in patients who are conscious of pigmented gingiva and want an esthetically satisfactory color.

    The role of HLA phenotype as a risk factor for drug-induced gingival overgrowth was investigated in a cohort of 172 transplant recipients. Clinically significant overgrowth warranting surgical correction was observed in 72 patients (42%). Using stepwise regression modelling, 6 clinical parameters were identified as significant risk factors for the severity of gingival overgrowth. These were; age, sex, creatinine plasma level, duration of therapy, papilla bleeding index and concomitant medication with a calcium channel blocking drug. 3 HLA alleles were also identified as risk factors when adjusted for other clinically significant risk factors (HLA -DR2, A24, B37). However, when the p-values for the HLA variables were corrected to compensate for the use of multiple significance testing, only HLA-B37 remained statistically significant at the 5% level. Organ transplant patients are at risk of developing gingival overgrowth, with approximately 25% medicated with cyclosporin alone requiring corrective gingival surgery. This figure more than doubles in patients concomitantly medicated with a calcium blocking drug. The data at present available would suggest that the severity of gingival overgrowth is also significantly associated with the HLA-B37 phenotype.

    Full Text Available Background. Hereditary gingival fibromatosis is a fibrotic enlargement of the gingiva. It may exist as an isolated abnormality or as part of multisystem syndrome. This paper reports a case of 16-year-old male with generalized severe gingival overgrowth, involving the maxillary and mandibular arches and covering almost all teeth. Methods. Periodontal management of gingival enlargement included gingivectomy in both arches except in the lower right molar region where flap surgery was done under general anesthesia. After a 2-month followup period, orthodontic treatment was started with fixed appliances. Monthly periodontal checkups and maintainance (scaling and polishing were scheduled to control the gingival inflammation. Results. Reevaluation of the patient of surgical treatment after two months did not show any recurrence of condition; however, minimal overgrowth was noted 1 month after the beginning of orthodontic treatment which was treated nonsurgically. Conclusions. Although the risk of recurrence is high with this condition, surgical treatment with correction of malocclusion and regular followup can provide excellent outcome as seen in this case.

    To compare clinical results of three types of manual tooth brushes on plaque removal efficacy and gingivitis. This study is a single blind randomized trial with crossover design which involved 30 periodontaly healthy individuals. Professional plaque removal and oral hygiene instruction were performed for all the participants in the first step of our study followed by asking them to avoid brushing for 2 days. Thereafter plaque and gingivitis scores were measured using plaque and gingival indices (PI and GI). Then subjects were instructed to use Pulsar tooth brush for a two-week period and then, GI and PI indices were assessed again. After passing one-week period for wash out, subjects didn't brush for 2 days and indices were recorded again. The same procedure was done for CrossAction, and Butler 411 tooth brushes respectively and at the end of the study these variables were analyzed using SPSS software ver.16. Repeated measurement ANOVA test was used to compare the scores between different brushes. Finding of this study reveals that using all three types of tooth brushes resulted in significant plaque and gingivitis reduction compared to baseline levels. Pulsar tooth brush was significantly more effective in diminishing PI and GI than Butler tooth brush (p=0.044 and 0.031 respectively). According to our findings all 3 types of tooth brushes are effective in reduction of plaque and gingivitis and this reduction is significantly greater for Pulsar tooth brush compared to Butler and CrossAction tooth brushes.

    Periodontal disease is the most common oral disease in cats. The objectives of this study were to determine the relationships between gingivitis and dental calculus thickness (DCT), or dental calculus coverage (DCC); determine the association of gingivitis scores and types of oral bacteria; and to evaluate bacterial co-infection in cats with periodontal disease. Twelve cats that were not infected with feline leukemia or feline immunodeficiency viruses were enrolled in the study. Gingivitis, DCT, and DCC were scored and recorded. A Kruskal-Wallis test was used to compare scores among canine, 2nd premolar, 3rd premolar, 4th premolar, and 1st molar teeth. The relationship between gingivitis and DCT or DCC scores was determined using the Spearman rank sum test (ρ). Subgingival bacteria were cultured and the association between bacterial species and gingivitis score was evaluated using a Fisher's exact test. The average gingivitis, DCT, and DCC scores for the caudal maxillary teeth were higher for the caudal mandibular teeth and more severe for the 3rd premolar, 4th premolar, and 1st molar teeth than for the canine teeth. A strong relationship between average DCT or DCC score and average gingivitis score was found (ρ = 0.96 and 1, respectively). Aerobic and anaerobic bacterial infections were identified in a large number of cats with periodontal disease (71.1% and 28.9%, respectively). In conclusion, severe gingivitis scores were associated with anaerobic bacterial infection. The caudal teeth are affected with more severe gingivitis, DCT, and DCC than the other teeth. Antibiotic prophylaxis should be prescribed in cats with periodontal disease.

    To evaluate the efficacy of a marketed oscillating-rotating (O-R) power toothbrush (Oral-B Triumph with SmartGuide and FlossAction brush head, D34/EB25) to a new sonic toothbrush (Sonicare FlexCare Platinum) in the reduction of gingivitis and plaque over a 12-week test period. This was a single center, randomized, open label, examiner-blind, two-treatment, parallel group study. Subjects who met the entrance criteria were enrolled in the study and randomly assigned to either the O-R or sonic treatment group. Subjects brushed with their assigned toothbrush and a marketed fluoride dentifrice for two minutes twice daily at home for 12 weeks. Gingivitis and plaque were evaluated at Baseline, Week 6, and Week 12. Gingivitis was assessed using the Modified Gingival Index (MGI) and Gingival Bleeding Index (GBI), and plaque was assessed using the Rustogi Modified Navy Plaque Index (RMNPI). Data were analyzed using an Analysis of Covariance (ANCOVA) with Baseline as the covariate. In total, 130 subjects (65 per group) were randomized to treatment and 127 subjects completed the study. Both brushes produced statistically significant (p gingivitis and plaque measures relative to Baseline. At Week 12, the O-R brush demonstrated significantly greater reductions than the sonic brush in whole mouth gingivitis measures (p = 0.007). Additionally, the O-R brush presented significantly fewer bleeding sites (p gingivitis, 19.8% for number of bleeding sites, and 12.2% for whole mouth plaque. There were no adverse events reported or observed for either brush. The oscillating-rotating toothbrush demonstrated statistically significantly greater reductions in whole mouth plaque at Weeks 6 and 12, as well as significantly greater gingivitis reductions over the long-term (12 weeks), compared to the new sonic toothbrush.

    Dental calculus has been implicated in the aetiology of several periodontal conditions. Its prevention and removal are therefore desirable clinical goals. While it is known that calculus is very variable in chemical composition, crystallinity and crystallite size little is known about site specific variability within a dentition and between individuals. With this in mind, a study was undertaken to investigate the comparative site specific nature and composition of human dental supra-gingival dental calculus obtained from 66 male patients visiting for their dental check-up using fluorescent X-ray spectroscopy, X-ray diffractometry and Fourier transform infrared spectroscopy. The supra-gingival dental calculus formed on the lingual surfaces of lower anterior teeth and the buccal surfaces of upper molar teeth were classified into four types based on calcium phosphate phases present. There was significant difference in composition of the crystal phase types between lower and upper teeth (pdental calculus on anterior or molar teeth of all samples. The degree of crystallinity of dental calculus formed on the upper molar teeth was higher than that formed on the lower anterior teeth (pdental calculus formed on the lower anterior teeth were higher than on upper molar teeth (pdental supra-gingival dental calculus is related to its location in the mouth.

    Burn injuries are among the most serious causes of radical changes in body image. The subject of body image and self-image is essential in rehabilitation, and the nurse must be aware of the issues related to these concepts and take them seriously into account in drafting out the nursing programme. This paper defines certain key words related to body image and discusses the social context of body image. Burn injuries are considered in relation to the way each of these affects the patient's body image. The aim of nursing is defined and the nurse's role in cases of severe changes in body image due to burn injuries is discussed.

    Full Text Available Abstract Background Road traffic accidents are the leading cause of fatal and non-fatal injuries in Vietnam. The purpose of this study is to estimate the costs, in the first year post-injury, of non-fatal traumatic brain injury (TBI in motorcycle users not wearing helmets in Hanoi, Vietnam. The costs are calculated from the perspective of the injured patients and their families, and include quantification of direct, indirect and intangible costs, using years lost due to disability as a proxy. Methods The study was a retrospective cross-sectional study. Data on treatment and rehabilitation costs, employment and support were obtained from patients and their families using a structured questionnaire and The European Quality of Life instrument (EQ6D. Results Thirty-five patients and their families were interviewed. On average, patients with severe, moderate and minor TBI incurred direct costs at USD 2,365, USD 1,390 and USD 849, with time lost for normal activities averaging 54 weeks, 26 weeks and 17 weeks and years lived with disability (YLD of 0.46, 0.25 and 0.15 year, respectively. Conclusion All three component costs of TBI were high; the direct cost accounted for the largest proportion, with costs rising with the severity of TBI. The results suggest that the burden of TBI can be catastrophic for families because of high direct costs, significant time off work for patients and caregivers, and impact on health-related quality of life. Further research is warranted to explore the actual social and economic benefits of mandatory helmet use.

    Full Text Available Objective: A double-blinded controlled clinical trial with parallel groups was designed to investigate the effectiveness of a herbal-based toothpaste in the control of plaque and gingivitis as compared with a conventional dentifrice. The efficacy of Colgate Herbal over Colgate tooth paste was assessed in this study. Materials and Methods: Thirty subjects with gingivitis participated in the study. All participants had at least 20 natural teeth with no probing depths greater than 3 mm and a plaque index score of 2 or more at baseline. At baseline, the clinical parameters like gingival index, plaque index and salivary pH were estimated. Paired t-test was used to compare the difference within the groups and unpaired t-test was used to compare the difference between the groups at baseline and on the 30 th day. Results: At the end of the study, there were statistically significant reductions in the gingival index and the plaque index scores within the test group. However, there were no statistically significant differences between the test and the control groups. The salivary pH changes were not statistically significant in the test group but were displaced more toward the acidic range in the control group. Conclusion: It was however concluded that the herbal-based toothpaste was as effective as the conventionally formulated dentifrice in the control of plaque and gingivitis.

Aerobic and anaerobic bacterial infections were identified in a large number of cats with periodontal disease (71.1% and 28.9%, respectively). In conclusion, severe gingivitis scores were associated with anaerobic bacterial infection. The caudal teeth are affected with more severe gingivitis, DCT, and DCC than the other teeth. Antibiotic prophylaxis should be prescribed in cats with periodontal disease. PMID:28154463

    The objective of this study is to assess the presence of plaque, gingivitis, and caries in a group of Sudanese children with congenital heart defects CHDs (cases) and compare them to children without CHDs (controls). This analytical cross-sectional study included cases (N = 111, with a mean age of 7.2 ± 3.0 years) and controls (N = 182, with a mean age of 7.2 ± 2.8 years) from Khartoum, Sudan. Examinations were done by two calibrated dentists using plaque index, gingival index, and WHO (World Health Organization) caries diagnostic criteria (dmft/DMFT index: decayed, missing, and filled teeth). Children with CHDs (cases) had statistically significantly higher mean number of sites with plaque and gingivitis than children without CHDs (controls), although almost all children experienced plaque. Cases also experienced significantly higher mean dmft/DMFT than controls (age group 1, 3-7 years: 3.7 vs 2.3 and age group 2, 8-12 years: 1.3 vs 0.6). The Significant Caries Indices in cases (age groups 1 and 2) were also significantly higher than among controls (SiC 8.2 vs 5.9 and 1.8 vs 0.8, respectively). Fillings were totally lacking among cases and scarce among controls. The findings clearly showed that this group of Sudanese children with CHDs was more severely affected with gingivitis and caries than the control group without CHDs. These results are cause for concern in children at risk of developing systemic infections and serious complications related to poor oral health. These findings provide important baseline data for planning appropriate dental preventive strategies for Sudanese children with CHDs.

    The clinical impact of posterior crown margin placement on gingival health has not been thoroughly quantified. This study evaluated the effect of posterior crown margin placement with multivariate analysis. Ten general dentists reviewed 240 patients with 480 metal-ceramic crowns in a prospective clinical trial. The alloy was randomly selected from 2 high gold, 1 low gold, and 1 palladium alloy. Variables were the alloy used, oral hygiene index score before treatment, location of crown margins at baseline, and plaque index and sulcus bleeding index scores recorded for restored and control teeth after 1 year. The effect of crown margin placement on sulcular bleeding and plaque accumulation was analyzed with regression models (Prisk of bleeding at intrasulcular posterior crown margins was approximately twice that at supragingival margins. Poor oral hygiene before treatment and plaque also were associated with sulcular bleeding. Facial sites exhibited a lower probability of sulcular bleeding than lingual surfaces. Type of alloy did not influence sulcular bleeding. In this study, placement of crown margins was one of several parameters that affected gingival health.

    Full Text Available Background/Aim. Several cytokines and lymphokines (IL1β, ENA78, IL6, TNFα, IL8 and S100A8 are expressed during dental pulp inflammation. Analysis of gingival crevicu-lar fluid (GCF offers a non-invasive means of studying gen-eral host response in oral cavity. Although GCF levels of various mediators could reflect the state of inflammation both in dental pulp and gingiva adjacent to a tooth, GCF samples of those without significant gingivitis could be inter-preted as reflection of pulpal process. The aim of this study was to investigate IL9 GCF values in patients with dental car-ies and to assess possible influence of various dental fillings materials on local IL9 production. Methods. The study group included 90 patients, aged 18–70, with inclusion and exclusion criteria in the prospective clinical study. Of the 6 types of material used for the restoration of prepared cavities, 3 were intended for temporary and 3 for definitive restora-tion. According to dental fillings weight, all the participants were divided into 3 groups: those with fillings lighter than 0.50 g, those with 0.50–1.00 g, and those with fillings heavier than 1.00 g. Samples were taken from gingival sulcus using the filter paper technique. Clinical parameters were deter-mined by bleeding index, plaque index (Silness-Lou, 0–3, gingival index (0–3, and gingival sulcus depth. Cytokine con-centrations were assessed using commercially available cy-tomix. Results. According to the weight of dental fillings, there was a clear decreament trend of IL9 values meaning that dental defects greater than 1.00 g of dental filling were associated with lower GCF IL9 concentration. The IL9 val-ues correlated with the degree of gingival index and depth of gingival sulcus, being higher with more advanced gingivitis and more pronounced anatomical changes in the tooth edge. Different filling materials exerted various local IL9 responses. Zink polycarbonate cement and amalgam fillings induced

    Full Text Available Objective: To assess the gingival health of children who attended the Preventive Program for pregnant women and babies and correlate theresults obtained with the assiduousness of attending the consultations offered by the program, oral hygiene habits, mother’s educational level, family income, child’s age and the number of carious surfaces. Methods: Three hundred and forty-one patients were selected, and divided into two groups for comparative purposes. Group 1 (experimental was composed of 262 children of both sexes, between the ages of three and six, who attended the Preventive Program for pregnant women and babies; Group 2 (control consisted of 79 children in the same age group, who did not attend the Preventive Program for pregnant women and babies, but who were attended at the Social Perinatological Institute of Piaui by other health professionals. The exams were performed in dental offices to determine the Gingival Bleeding Index. Results: It was noted that 74.8% of the children from experimental group and 82.3% of control group presented gingival bleeding in one of the sites assessed. Lower Gingival Bleeding Index values were related to the higher educational level of the mothers, supervision or brushing by adults and increase in the number of daily brushings. The Chi-square test showed that the variables are dependent (p<0.001, that is, Gingival Bleeding Index is subject to the number of consultations attended at the Preventive Program for pregnant women and babies. Spearman’s Coefficient (= -0.292 proved that the higher the number of consultations attended at the program, the lower was the Gingival Bleeding Index (p<0.001. Conclusion: The children who presented the lowest gingival bleeding indexes were those who most assiduously attended the preventive maintenanceconsultations of the Preventive Program for pregnant women and babies.

    Full Text Available Background/purpose: An ideal therapeutic procedure for the treatment of gingival recession associated with an NCCL has presented a challenge to clinicians. Various dental materials and surgical approaches have been used to manage gingival recessions associated with NCCLs for the most predictable combined surgical/restorative treatment. The objective of this study was to evaluate the treatment of gingival recessions associated with non-carious cervical lesions (NCCL using a modified coronally advanced flap (MCAF in combination with a connective tissue graft (CTG on restored root surfaces. Materials and methods: Twenty-three systemically healthy subjects, who were positive for the presence of three cervical lesions associated with gingival recessions in three different adjacent teeth, were enrolled in the study. The NCCL were each restored prior to surgery by using one of three different materials: nanofilled composite resin (NCR, resin-modified glass ionomer cement (RMGI or giomer. The gingival recession defects were treated by CTG. Results: Inter-group differences were not statistically significant for probing depth (PD, relative recession height (rRH, relative clinical attachment level (rCAL, keratinized tissue width (KTW or keratinized tissue thickness (KTT (p > 0.05 among the groups at any time. The mean percentage of defect coverage was 71.18 ± 23.16% for NCR + CTG group; 71.33 ± 22.33% for RMGI + CTG group; and 64.23 ± 20.33% for giomer + CTG group at 1 year postoperatively (p > 0.05. Conclusion: The combined surgical/restorative treatments provided successful clinical results. Giomer + CTG may be less effective compared to other groups for treatment of gingival recession associated with NCCL.

    Short-term use of sodium bicarbonate (NaHCO3)-containing toothpaste reduces plaque and improves clinical measures of gingivitis. To examine this over a longer period, we compared efficacy and tolerability of twice-daily brushing for 24 weeks with 67% or 0% NaHCO3-containing toothpastes in USA-based participants with moderate gingivitis (Clinicaltrials.gov:NCT02207400). This was a six-month, randomized, examiner-blind, parallel-group, clinical trial. Investigators randomized adults with blood in expectorate after brushing and ≥ 20 gingival bleeding sites to 67% NaHCO3 (n = 123; n = 107 completed study) or 0% NaHCO3 (n = 123; n = 109 completed study) toothpastes. Primary efficacy variables included between-treatment differences in number of bleeding sites and Modified Gingival Index (MGI) score at 24 weeks. Secondary efficacy variables included Bleeding Index and Turesky modification of the Quigley-Hein Plaque Index (overall and interproximal sites) at six, 12, and 24 weeks. A subset of 50 participants underwent sampling to assess plaque microbiology over the course of treatment. Compared with the 0% NaHCO3 toothpaste, the 67% NaHCO3 toothpaste produced statistically significant improvements at Week 24 in number of bleeding sites (46.7% difference) and MGI (33.9% difference), and for all other endpoints (all p < 0.0001). There was no significant between-treatment difference in the proportion of participants harboring opportunistic pathogens. Products were generally well tolerated, with two and five treatment-related adverse events reported in the 67% and 0% NaHCO3 toothpaste groups, respectively. Gingival bleeding, gingivitis, and plaque indices were significantly improved at six, 12, and 24 weeks with twice-daily brushing with 67% NaHCO3-containing toothpaste in participants with moderate gingivitis.

    To evaluate the efficacy of a power toothbrush with distinct multi-directional cleaning action using two different heads (Colgate ProClinical C200 toothbrush with either a triple clean head or a sensitive head) as compared to a manual flat-trim toothbrush (Oral B Indicator toothbrush) on supragingival plaque and established gingivitis. This examiner-blind, randomized, controlled, three-treatment, parallel-group clinical research study assessed plaque removal via the comparison of pre- to post-brushing after a single use and again after four weeks of use, using the Rustogi Modified Navy Plaque Index. This study also assessed gingivitis at four weeks using the Löe-Silness Gingival Index. Qualifying adult male and female subjects from the central New Jersey, USA area reported to the study site after refraining from any oral hygiene procedures for 24 hours, and from eating, drinking, and smoking for four hours. Following an examination for plaque and gingivitis, they were randomized into three balanced groups. Subjects were instructed to brush their teeth for two minutes under supervision with their assigned toothbrush and a commercially available toothpaste (Colgate Cavity Protection toothpaste), after which they were again evaluated for plaque. Subjects were dismissed from the study site with the toothpaste and their assigned toothbrush to use at home twice daily for the next four weeks. They reported to the study site after four weeks of product use, at which time they were evaluated for plaque and gingivitis. One hundred twenty (120) enrolled subjects complied with the protocol and completed the clinical study. The results of the study indicated that all three test products provided statistically significant reductions in pre-brushing to post-brushing plaque scores for whole mouth and interproximal sites after a single use. For gingival margin plaque sites, only the Colgate ProClinical C200 toothbrush, with either the triple clean head or the sensitive head

    Full Text Available Background: Studies assessing the prevalence of oral lesions in children and adolescents, particularly in gingiva are scarce in the literature. The aim of the study was to describe the distribution of gingival proliferative lesions based on clinical and histopathological diagnoses in children and adolescents. Materials and Methods: A review of clinical charts of children and adolescents aged between 0 and 18 years old, admitted to the Oral Medicine Outpatient Unit, of Universidade Federal do Paraná, for 15 years (1994–2009 was performed. Results: Six hundred and sixty-nine out of 5,129 patients treated during this period were aged between 0 and 18 years old, and 45 of these had gingival lesions. The largest number of lesions was observed between 11 and 16 years old. The majority of the patients were referred by Curitiba's public health system. Pyogenic granuloma was the most frequent lesion (19 = 42.2%, followed by peripheral giant cell lesion (11 = 24.4%, gingival fibromatosis (10 = 22.2%, and peripheral ossifying fibroma (5 = 11.1%. Conclusion: Gingival proliferative lesions can show similar clinical characteristics. Appropriate clinical and histopathological diagnoses are necessary to guide the healthcare professional to establish the adequate treatment and to estimate the risk of recurrence.

    This study compared the use of diode and Er:YAG lasers in treating gingival melanin pigmentation (GMP) in terms of gingival depigmentation, local anesthesia requirements, postoperative pain/discomfort, depigmentation effectiveness, and total treatment duration. Twenty patients (13 female, 7 male) referred with GMP were enrolled in the study. Patients were randomly divided into 2 groups. Group 1 was treated with a gallium aluminum arsenide diode laser with a continuous wavelength of 808 nm, and group 2 was treated with an Er:YAG laser with a continuous wavelength of 2,940 nm. Gingival depigmentation was performed by applying the laser at 1 W. Treatment was administered on a weekly basis until a normal pink gingival color was observable in clinical examination and photographs. In addition, patients were asked to evaluate the procedure by using a self-administered questionnaire. Procedures were carried out without the need for any topical or local anesthetic, and no unpleasant events occurred during the actual procedure or the healing period. The total length of treatment was significantly shorter with the diode laser (group 1) than with the Er:YAG laser (group 2; P Diode and Er:YAG lasers administered at 1 W both result in satisfactory depigmentation of GMP.

    Erosive oral lichen planus and desquamative gingivitis are uncommon but severe debilitating variants of oral lichen planus. Treatment of these presentations is difficult and challenging. A 44-year-old woman was referred to the dermatology clinic with chronic painful lichen planus-related gingivitis and buccal erosions. She has failed multiple treatments including topical clobetasol and tacrolimus, intralesional corticosteroids and several systemic and immunosuppressive agents. Following completion of three months of treatment with oral apremilast at a dose of 30 mg twice daily, significant improvement was noted in her disease activity. Oral apremilast may be a safe and effective treatment for erosive oral lichen planus.

    To evaluate and compare the efficacy of an oscillating-rotating (O-R) power toothbrush with a brush head utilizing angled bristles to a marketed sonic toothbrush in the reduction of plaque and gingivitis over an eight-week period. This study used a randomized, examiner-blind, single-center, two-treatment, parallel group, eight-week design. Subjects with mild-to-moderate plaque and gingivitis were evaluated for baseline whole mouth, gingival margin, and approximal plaque, gingivitis, and gingival bleeding. Clinical assessments were performed using the Modified Gingival Index, Gingival Bleeding Index, and the Rustogi Modified Navy Plaque Index. Subjects received either the O-R brush (Oral-B Professional Care 1000 [D16u] with Oral-B CrossAction brush head [EB50]) or the sonic brush (Sonicare DiamondClean with the standard DiamondClean brush head). Subjects brushed twice daily for two minutes per brushing with the assigned brush and a standard fluoride dentifrice for eight weeks before returning for plaque and gingivitis evaluations using the same methods. Prior to baseline and Week 8 measurements, participants abstained from oral hygiene for 12 hours. One hundred and forty-eight subjects completed the study; 75 in the O-R group and 73 in the sonic group. Both brushes demonstrated statistically significant reductions in plaque and gingivitis over the eight-week study period (p gingivitis than the sonic brush. Whole mouth, gingival margin, and approximal plaque reductions were 27.7%, 46.8%, and 29.3% greater, respectively, compared with the sonic brush, while the reductions in gingivitis, gingival bleeding, and number of bleeding sites were 34.6%, 36.4%, and 36.1% greater, respectively, for the O-R brush than for the sonic brush (p gingivitis reductions for the O-R power brush incorporating the angled-bristled brush head were significantly greater than for the sonic power brush.

    Gestational diabetes mellitus (GDM) is defined as varying glucose intolerance, with first onset or recognition in pregnancy. This study evaluates clinical and biochemical parameters in a possible association between GDM and gingivitis. A total of 167 pregnant females was included in the study. There were 101 females with GDM and 66 females without GDM. Subgroups were created according to the presence or absence of gingival inflammation. Plaque index, bleeding on probing, and probing depth were recorded at four sites per tooth. Serum, saliva, and gingival crevicular fluid (GCF) levels of interleukin (IL)-6, IL-8, soluble receptor activator of nuclear factor-kappa B ligand (sRANKL), osteoprotegerin (OPG), B-cell activating factor (BAFF), and a proliferation-inducing ligand (APRIL) were determined by enzyme-linked immunosorbent assay. Data were analyzed by Kruskal-Wallis and Mann-Whitney U tests and Spearman correlation analysis. Age and anthropometric indices were higher in the GDM than non-GDM group (P gingivitis group than non-GDM with gingivitis group (P = 0.044). Serum and GCF BAFF (P gingivitis group than GDM without gingivitis group. The inflammatory response seems to be more pronounced in females with GDM. The observed increase in both local and systemic levels of inflammatory cytokines may suggest an interaction between gingivitis and GDM.

    Obesity induces gingival oxidative stress, which is involved in the progression of alveolar bone resorption. The antioxidant effect of hydrogen-rich water may attenuate gingival oxidative stress and prevent alveolar bone resorption in cases of obesity. We examined whether hydrogen-rich water could suppress gingival oxidative stress and alveolar bone resorption in obese rats fed a high-fat diet. Male Fischer 344 rats ( n = 18) were divided into three groups of six rats each: a control group (fed a regular diet and drinking distilled water) and two experimental groups (fed a high-fat diet and drinking distilled water or hydrogen-rich water). The level of 8-hydroxydeoxyguanosine was determined to evaluate oxidative stress. The bone mineral density of the alveolar bone was analyzed by micro-computerized tomography. Obese rats, induced by a high-fat diet, showed a higher gingival level of 8-hydroxydeoxyguanosine and a lower level of alveolar bone density compared to the control group. Drinking hydrogen-rich water suppressed body weight gain, lowered gingival level of 8-hydroxydeoxyguanosine, and reduced alveolar bone resorption in rats on a high-fat diet. The results indicate that hydrogen-rich water could suppress gingival oxidative stress and alveolar bone resorption by limiting obesity.

    Full Text Available The destructive action of the chronic periodontitis on the periodontal tissues has provided a continuous challenge to the dental profession to develop better methods to achieve repair of the recession regions and even regeneration of post periodontal tissues. Aims: To assess the effect of periodontal muco-periostal flap surgery with gingival fiber retention technique on minimizing the post surgical recession. Materials and Methods: The sample for the study comprised of 20 patients. The criteria for selection included patients with moderate periodontitis, with minimum recession in the anterior teeth, with adequate width of the attached gingiva, and with no traumatic occlusion. Periodontal muco-periosteal flap surgery with gingival fiber retention technique was done in the experimental site with internal bevel incision, and in control site, muco periosteal flap surgery with crevicular incision was done. Thereafter, observation period was of one week, four weeks, and eight weeks were done for both the sites. Statistical Analysis Used: The results were subjected to statistical analysis using student′s t`-test. Results: The result of this study suggests that the periodontal flap surgery with gingival fiber retention technique has a beneficial effect on the anterior teeth, as it maintains the esthetics, recontours the gingiva with minimal recession. The area of recession was more on the control site as compared to experimental site at 4 weeks, 8 weeks and 12 weeks. Conclusions: Gingival fiber retention technique showed less post-surgical recession and also there was fall in values of plaque index, gingival index, and periodontal index scores, throughout the study.

    Fireworks or firecrackers can cause serious accidents. They are classified from K1 to K4 according to the amount of powder they contain. In Alsace (France), a type-K1 firecracker is available on the free market and the K2 and K3 ones are prohibited. The aim of this study was to reveal the effects of measures taken in order to prevent repercussions related to hand injuries caused by fireworks. Patients who fell victim to firework incidents have been recorded since 2006, starting date of the prevention campaign. Records have been taken on the circumstances, the group of firecracker, the level of injury and the severity of the injury in four stages. Our series included 62 hands from 58 patients (average age: 25 years), including two women. Most of them sustained their injury during the night of New Year's Eve. The study dealt with 21 K1, and 35 K2 or K3. We registered 29 cases of grade I, 2 grades II, 21 grades III and 9 grades IV. One patient died. The numbers of consultations, K2/K3 injuries and number of surgeries increased from 2006 to 2012. Our results show that firework-related injuries to the hand are serious, pluridigital, multistage and/or bilateral. Prevention was ineffective but should be improved and strengthened, as a total ban on fireworks is a counterproductive measure. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Full Text Available The dental alloy is widely used in many fields of dentistry as a restoration material, orthodontic, prosthodontic, oral surgery and endodontic treatments. Naturally, most of the metallic materials without exception to stainless steel alloy will experience a process of corrosion in a form of electrochemical reaction to achieve thermodynamic equilibrium. The corrosion process in the oral cavity is due to the reaction of metal with saliva as an oral cavity electrolyte fluid. SSC has preformed restoration material conform with dental anatomy, manufactured from stainless steel alloy which is formable and adaptable to the teeth. Stainless Steel Crown generally made of austenitic stainless steel 18/8 of AISI 304 group contain chrome 18% and Nickel 8%, can be used as a restoration for teeth with excessive caries, crown fracture, email hypoplasia, or restoration after endodontic treatment. The toxic effect of Ni+2 released due to corrosion process may cause an inflammation of the gingiva and periodontal tissue. Laboratorically this condition indicated by the expression of pro-inflammation cytokines as immunological parameters such as IL-6, IL-8, TNF and IL-1β whose main role is to initiate and enhance any inflammation responses. The presence of pro-inflammation cytokines can be detected as soon as 1 hour after placement of SSC by examination of gingival crevicular fluid (GCF by ELISA technique. The magnitude of the toxic effect depends on corrosion rate and ions release which is influenced by metal chemical composition, environment temperature and pH, metal wear due to abrasion and friction, soldering if any, and elongation of the metal. Conclusion: The release of Ni+2 during corrosion process after placement of SSC cause gingival inflammation which is indicated by the change of the immunological parameters.

    The aim of this study was to assess the incidence and patterns of work-related maxillofacial injuries, identifying worker categories with a high risk of injury. From a systematic computer-assisted database that has continuously recorded patients hospitalized with maxillofacial fractures, only patients with work-related injuries were considered. Occupation, mechanism of injury, and demographic and clinical data were analyzed. Work-related facial injuries represented the fifth most common cause of injury, with a percentage of 6.3 %. Maxillofacial fractures were most often seen in construction workers (37.9 %). The middle third was involved in 67 % of the cases; the mandible was the most frequently injured site. Work-related maxillofacial trauma is rare, but it is often complex and challenging as Facial Injury Severity Scale values show. In agreement with the few published reports, construction workers, together with farm and forestry workers, are at the highest risk of injuries, mainly because of struck by a thrown, projected, or falling object.

    Full Text Available An association between closed posterior elbow dislocation and traumatic brachial artery injury is rare. Absence of radial pulse on palpation is an important warning sign and arteriography is the gold-standard diagnostic test. Early diagnosis is essential for appropriate treatment to be provided. This consists of joint reduction and immobilization, along with urgent surgical restoration of arterial flow. Here, a case (novel to the Brazilian literature of an association between these injuries (and the treatment implemented in a 27-year-old male patient is reported. These injuries were sustained through physical assault.

    Heat-delivery devices have been associated with relatively high temperatures. Previous basic research studies suggest that the risk for periodontal tissues is negligible, as the presence of the root filling materials, amongst other factors, reduce the risk of overheating. This report describes the case of a 45 year old male, who was undergoing restorative treatment in a multi-specialty dental practice. As part of his overall treatment planning, orthograde root canal retreatment for his maxillary left incisor teeth was deemed necessary, due to chronic apical periodontitis. Following cold lateral compaction, the coronal portion of the core material was severed using a System B Heat Source (Kerr Dental, Orange, CA, USA), with the patient reporting pain as well as a burning sensation. The following day the patient was seen by a periodontist and gingival necrosis in relation to the central incisor was found. The most likely cause of the complication was considered to be excessive heat during the operative procedure. The patient was followed up for a 2-year period and the soft tissues returned to their original condition without the need for periodontal treatment. © 2017 Australian Dental Association.

    Extensive gingival recessions associated with cervical abrasions are common among the population. Several different surgical and/or restorative therapies have been proposed to correct these lesions. This manuscript reports the treatment of multiple gingival recessions associated to cervical abrasions. The procedure involved the utilization of subepithelial connective tissue graft (SCTG) combined with coronally advanced flap onto a previously restored root surface. At the postoperative follow-up visits, the success of the restorative/surgical approach was confirmed by the absence of bleeding to probing and periodontal pockets as well as presence of gingival tissue with normal color, texture and contouring. After 18 months of follow-up, the clinical conditions are stable with satisfactory root coverage and periodontal health. An excellent esthetical outcome was achieved and the patient is satisfied with case resolution. PMID:19826605

    Full Text Available La sonrisa es una de las expresiones más comunes del ser humano como muestra de satisfacción, alegría o felicidad. Algunas personas al sonreír muestran la encía por encima de la base de los dientes, lo que ocasiona un aspecto antiestético. Esta situación repercute negativamente en el individuo, ya que altera la espontaneidad de la expresión facial. En el origen de la sonrisa gingival intervienen factores dentales, esqueléticos y de tejidos blandos. Proponemos una variante quirúrgica innovadora para corregir la sonrisa gingival en pacientes con alteraciones de los tejidos blandos. Se intervinieron quirúrgicamente 15 mujeres de entre 17 y 38 años de edad. En 7 de ellas se practicó rinoplastia además de corrección de la sonrisa gingival. Las 8 restantes se sometieron exclusivamente a corrección de la sonrisa gingival. Las 15 pacientes intervenidas mejoraron su apariencia y autoestima. No hubo complicaciones o problemas relacionados con la herida quirúrgica. Los resultados han sido permanentes a medio y largo plazo. La sonrisa de las pacientes es normal, mejoró su expresión y se conservaron la sensibilidad y la función muscular. La técnica propuesta es sencilla y de fácil reproducción; el tiempo quirúrgico estimado es de una hora y la operación es de tipo ambulatoria. Suele ser bien tolerada por los pacientes y no altera sus actividades cotidianas.Human beings possess a highly expressive face, there are people who when smile, show the gums above the base of the teeth causing an antiesthetic aspect.

    The aim of this study was to review the efficacy and toxicity of radiation therapy with concurrent retrograde superselective intra-arterial chemotherapy in the treatment of gingival carcinoma. In all, 34 patients (21 men and 13 women) with squamous cell carcinoma of the gingiva underwent radiation therapy with concurrent retrograde superselective intra-arterial chemotherapy. Treatment consisted of daily external irradiation and concurrent retrograde superselective intra-arterial infusion with cisplatin and docetaxel. A median total dose of 60 Gy in 30 fractions was delivered to tumors. Of the 34 patients, 29 (85 %) achieved a complete response (CR) and 5 had residual tumors. Of the 29 patients with a CR, 2 had local recurrences and 1 had distant metastasis 1-15 months after treatment. Twenty-six of the 36 patients had survived at a median follow-up time of 36 months (range 12-79 months); 4 died of cancer and 4 died of non-cancer-related causes. At both 3 and 5 years after treatment, the overall survival rates were 79 % and the cause-specific survival rates were 85 %. Osteoradionecrosis of the mandibular bone only developed in 1 patient after treatment. Radiation therapy with concurrent retrograde superselective intra-arterial chemotherapy was effective and safe in the treatment of gingival carcinoma. This treatment may be a promising curative and organ-preserving treatment option for gingival carcinoma. (orig.) [de

    Full Text Available Background: Beta-defensins (BD are antimicrobial peptides that play a role in defense against pathogens. Beta-defensins (BD are expressed by a variety of epithelial cells, including gingival epithelium, salivary glands, saliva and salivary duct. BD-1 is expressed constitutively, while BD-2 and BD-3 expressions can be induced by commensal bacteria. Probiotics are commensal bacteria, thus L. reuteri as probiotic bacteria may act as “inducer” for BD-2 in epithelial gingiva. S. mutans is the main bacteria causing dental caries and sensitive to BD-2. Purpose: This study was aimed to prove that the administration of probiotic L. reuteri may improve BD-2 expressions in the gingiva epithelium. Method: This study was conducted in vivo using twenty-four male Rattus norvegicus Wistar strains aged 10-12 weeks and weighed 120-150 g. Those rats were randomly divided into four groups, namely negative control group (not induced with L. reuteri or S. mutans, positive control group (induced with S. mutans for 14 days, treatment group 1 (induced with L. reuteri for 14 days and S. mutans for 7 days, and treatment group 2 (induced with L. reuteri and S. mutans for 14 days concurrently. The concentration of L. reuteri used was 4x108cfu/ml, while the concentration of S. mutans was 1x 1010cfu/ml. 0.1 ml of each was dropped in the region of the mandibular incisors. BD-2 expression was calculated using immunohistochemical method. The difference of BD-2 expressions in gingival epithelial cells in the respective groups was analyzed by Anova/SPSS. Results: There were significant differences in BD-2 expressions in gingival epithelial cells in each group based on the results of Anova test (p=0.001. Conclusion: The administration of probiotic L. reuteri is able to increase BD-2 expressions in gingival epithelial cells.

    Although patients with diabetes are frequently affected by periodontitis, only a few investigations have focused on gingivitis in this at-risk population. This randomized placebo-controlled clinical trial compared the response to a gingivitis treatment protocol that combined mechanical procedures and daily use of an essential oil (EO) mouthrinse between patients with and without diabetes. The whole-mouth periodontal probing depth (PD), gingival index (GI), and plaque index (PI) were monitored in gingivitis cases among systemically healthy patients (n = 60) or those with diabetes (n = 60) at baseline and 3 months after treatment. Levels of Porphyromonas gingivalis, Tannerella forsythia, Aggregatibacter actinomycetemcomitans, and total bacterial load were determined by a real-time polymerase chain reaction in intrasulci plaque samples. The volume of gingival crevicular fluid (GCF) was quantified, and interleukin-1β (IL-1β) levels were determined in GCF samples. After a full-mouth ultrasonic debridement, patients were randomly assigned to an EO or a placebo rinse for 90 days (40 mL/day). The data were analyzed through repeated-measures analysis of variance and multiple comparisons Tukey tests (P diabetes group. Diabetes impaired GI and reduced GCF volume. PD, bacterial levels, and IL-1β improved similarly in both systemic conditions. The adjunctive use of EO provided greater reductions of PI, GI, total bacterial load, T. forsythia, A. actinomycetemcomitans, and GCF volume. Response to gingivitis treatment in patients with diabetes can slightly differ from that in patients without diabetes. Daily use of an EO mouthrinse after ultrasonic debridement benefited patients with and without diabetes.

    Full Text Available Introduction: Importance of good smile cannot be underestimated in enhancement of beauty, self-confidence and personality of a person. Health and appearance of gingiva is an essential part of attractive smile. Gingival pigmentation gives rise to unesthetic smile line. In present world, with increasing awareness to esthetic, people have become highly concerned about black gums. Various treatment modalities like abrasion, scrapping, scalpel technique, cryosurgery, electrosurgery and laser are available for treatment of gingival pigmentation. The present study was conducted with an objective of comparing efficacy of gingival depigmentation by cryosurgery and scalpel technique. Method: A Randomized control split mouth study was conducted for 25 patients with gingival pigmentation. Gingival pigmentation Index (GPI for pigmentation and Visual Analoug Scale (VAS for pain was evaluated for both test (Cryosurgery and control sites (Scalpel technique at baseline, 1month, 3months and 6 months. Results: GPI score was 3 and 2 for 21/25 and 4/25 control sites and was 22/25 and 3/25 test sites respectively at baseline. Both the groups showed significant reduction in GPI score i.e., 0 at 1 and 3 months interval after treatment. GPI score increased to 1 for 5/25 sites treated with scalpel technique and 2/25 sites treated with cryosurgery at 6 months interval (P=0.0691. This indicates recurrence rate for pigmentation is higher after scalpel treatment. VAS Score was 3 for 10/25 sites treated with scalpel and was 2 for 12/25 sites treated with cryosurgery (P<0.001. Conclusion: It can be concluded that cryosurgery can be effectively and efficiently used for depigmentation by keeping patients acceptance and comfort in mind and also the long term results and ease of use when compared to scalpel technique.

Ofrecen una amplia gama de presentación clínica y no siempre se diagnostican sin sorpresa. El tratamiento de estas lesiones siempre ha representado un reto para el cirujano debido a su intensa vascularización y a la elevada incidencia de recurrencia. Se presenta el caso de una malformación arterio-venosa intraósea en el maxilar superior que se manifiesta como sangrado gingival, cuyos exámenes radiológicos de rutina no fueron concluyentes. Se llevó a cabo la excisión quirúrgica y el empaquetado del hueso con cera, y se realizó el seguimiento del paciente durante 1 año sin que se produjera recurrencia. Las malformaciones vasculares deben tenerse en consideración en el diagnóstico diferencial del sangrado gingival con radiografías dentales no concluyentes.Intraosseous arterio-venous malformations (AVM in the maxillofacial region are rare clinical entities. They have a wide range of clinical presentation and are not always diagnosed without a surprise. Treatment of these lesions has always been a challenge to the surgeon due to extreme vascularity and the high recurrence rate. The case presented is that of an intraosseous arterio-venous malformation in the maxilla that started as gingival bleeding and routine radiographic examinations were inconclusive. Surgical excision and bone wax packing was performed there were no recurrences during 1-year of follow-up. Vascular malformations may be considered in differential diagnosis of gingival bleeding with inconclusive dental radiographs.

    To determine whether gingival crevicular fluid (GCF) and serum total antioxidant capacities (TACs) correlate with the degree of severity of periodontal disease in dogs. 41 Toy and Miniature Poodles. After assessment of the degree of severity of naturally occurring periodontitis, GCF samples from both maxillary fourth premolars and a blood sample were collected from each dog. The condition of the periodontium of the entire dentition and at each site of GCF collection was recorded. Clinical parameters assessed included plaque index, gingival index, and probing depth. Radiographic analysis of alveolar bone level was also performed. Total antioxidant capacity was measured in GCF and serum samples by use of a commercial kit. Dogs with gingivitis and minimal periodontitis had significantly higher TAC in GCF than dogs with advanced periodontitis. Bivariate regression analysis revealed significant negative correlations between TAC in GCF and clinical parameters and age. The TAC in serum was significantly negatively correlated with the degree of gingival inflammation but was not significantly correlated with age. TAC in GCF is related to the degree of severity of periodontal disease in dogs. This is likely the result of release of reactive oxygen species by activated phagocytes and fibroblasts in the inflamed periodontal tissues. The results of our study suggest that the local delivery of antioxidants may be a useful adjunctive treatment for periodontitis in dogs.

    To investigate tree-related injuries in Solomon Islands by the types of trees involved, who is affected and the types of injuries caused. Descriptive case series of all cases of injuries related to trees presenting to the National Referral Hospital in Honiara from 1994 to 2011. Data were collected by the attending clinician using a Trauma Epidemiology form, which provides information on age, sex, cause of injury and type of fracture. Number of injuries by tree type, sex and age. Of the 7651 injuries in the database, 1107 (14%) were caused by falls from trees. Falls from coconut trees led to the highest number of injuries, followed by falls from mango, guava, apple and nut trees. Overall, 85% of injuries occurred in individuals aged trees, 77% of patients were aged tree types. Overall, 71% of injuries occurred among males. Of all injuries, 92% were fractures, 3% were dislocations and 5% were non-fracture, non-dislocation injuries. The arm (including wrist, elbow and hand) was the most common location of injury across all tree types. Distal radius fractures in the forearm were particularly common, as were ulna fractures. While mangos and guavas are undeniably delicious, the quest for their flesh can be hazardous. Children will always climb trees, but the search for food among children in lower-income settings may lead to higher rates of injury.

    Studies have reported commercially available essential oils with convincing plaque and gingivitis preventing properties. However, no tests have compared these essential oils, i.e. Listerine(®), against their true vehicle controls. To compare the plaque and gingivitis inhibiting effect of a commercially-available essential oil (Listerine(®) Total Care) to a negative (22% hydro-alcohol solution) and a positive (0.2% chlorhexidine (CHX)) control in an experimental gingivitis model. In three groups of 15 healthy volunteers, experimental gingivitis was induced and monitored over 21 days, simultaneously treated with Listerine(®) Total Care (test), 22% hydro-alcohol solution (negative control) and 0.2% chlorhexidine solution (positive control), respectively. The upper right quadrant of each individual received mouthwash only, whereas the upper left quadrant was subject to both rinses and mechanical oral hygiene. Plaque, gingivitis and side-effects were assessed at day 7, 14 and 21. After 21 days, the chlorhexidine group showed significantly lower average plaque and gingivitis scores than the Listerine(®) and alcohol groups, whereas there was little difference between the two latter. Listerine(®) Total Care had no statistically significant effect on plaque formation as compared to its vehicle control.

    Diabetes is one important risk factor of chronic periodontitis. However, the roles of toll-like receptor (TLR) 2 and TLR4, which are implicated in the inflammatory process in both chronic periodontitis and diabetes, have not been studied. This study aimed to determine whether TLR2 and TLR4 might be involved in the relationship between chronic periodontitis and diabetes by examining TLR2 and TLR4 expression in gingival tissues from subjects with chronic periodontitis without diabetes (CP) and with diabetes (CP+DM) and from periodontally healthy subjects without diabetes (PH) and with diabetes (PH+DM). Gingival tissues were collected from 23 CP subjects, 21 CP+DM subjects, 22 PH subjects and 20 PH+DM subjects. The expression of TLR2 and TLR4 in gingival tissues was determined using an immunohistochemical method. In gingival epithelium, staining patterns and intensity levels of TLR2 and TLR4 expression were studied. In connective tissues, the percentages of TLR2- and TLR4-positive cells were calculated. The intensity levels and the percentages of positive cells were statistically analyzed. Chronic periodontitis or diabetes showed no significant effect on TLR2 expression in the oral epithelium. However, diabetes increased the expression of TLR2 in sulcular epithelium and changed the pattern of TLR2 expression in gingival epithelium. Chronic periodontitis decreased the expression of TLR4 in gingival epithelium. In connective tissue under sulcular epithelium, CP+DM subjects showed statistically significant higher percentages of TLR2- and TLR4-positive cells compared with PH and PH+DM subjects. Our results suggest that hyperglycemia and chronic periodontitis had effects on TLR2 and TLR4 expression in gingival tissue. The differences in TLR2 and TLR4 expression could contribute to a greater inflammatory response, leading to periodontal disease initiation and progression. © 2013 John Wiley & Sons A/S.

    This work aims to determine the effect of cytosolic bacteria on the expression of cyclic GMP-AMP synthase (cGAS) in human periodontal ligament cells (hPDLCs) and gingival tissues. The ability of Porphyromonas gingivalis (P. gingivalis) to invade hPDLCs was detected using laser scanning confocal microscope assay at a multiplicity of infection of 10. P. gingivalis-infected cells were sorted by fluorescence-activated cell sorting (FACS). Then, quantitative real time reverse transcription polymerase chain reaction (qRT-PCR) and Western blot were used to detect cGAS expression in infected cells. Finally, the location and expression of cGAS in inflammatory and normal gingival tissues were investigated by immunohistochemistry. P. gingivalis actively invaded hPDLCs. Moreover, cGAS expression significantly increased in P. gingivalis-infected cells. Although cGAS was expressed in the epithelial and subepithelial cells of both inflamed and normal gingival tissues, cGAS expression significantly increased in inflamed gingival tissues. Cytosolic bacteria can upregulate cGAS expression in infected cells. These data suggest that cGAS may act as pattern-recognition receptors and participate in recognizing cytosolic nucleic acid pathogen-associated molecular patterns.

    Full Text Available AIM: Literature is replete with studies on gingival recession, the apical shift of the gingival margin from the cemento-enamel junction. Chronic periodontitis and frequent toothbrushing are among its aetiological factors. Many of these were however prevalence studies. The current study was therefore aimed at separating prognostic indicators from determinants of the number of recessions. METHOD: 650 consecutive adult patients visiting a Nigerian teaching hospital were examined using a checklist including plaque, calculus, Miller’s class of recession and other parameters.. A total of 408 recession sites were identified. RESULTS: The mean age of the patients with recession was 42.3 years; mean number of recession was 4.74 Incisors had the highest number of recessions (35.7%. While a factor such as age was related both to the number and prognosis of recession sites, abrasion and plaque were only related to prognosis. Again, some of the factors previously significantly related to prognosis on univariate analysis like calculus and smoking, lost their significance on regression analysis. CONCLUSION: The three strongest predictors of prognosis (Miller’s class of recession were age, plaque and abrasion. [TAF Prev Med Bull 2010; 9(3.000: 187-194
