Lipomas are benign soft tissue tumours composed mainly of mature adipose tissue. Histological variants of lipomas have been named according to the type of tissue present and they include fibrolipoma, angiolipoma, osteolipoma, chondrolipoma and others. Osteolipoma, a classic lipoma with osseous metaplasia, is a very rare histological variant. Owing to the rarity of oral osteolipomas, we report an uncommon case of osteolipoma located on the floor of the mouth of a 20-year-old female patient and include a review of the literature.

Disorders relating to short gestation and low birth weight are among the leading causes of death and disability in infants. About 25% of pre-term low birth weight (PLBW) cases occur without even a suspected risk factor. Of all PLBW cases, 18.2% may be attributable to periodontitis (Offenbacher et al. 1996). Therefore, this study was conducted to assess the views and knowledge of gynaecologist's on association between periodontal disease and pre-term low birth weight and their willingness to advise their patients to seek dental treatment. © 2011 Informa UK, Ltd.

Background: In today′s high strung lifestyle, stress plays a major role on our health. Studies using ultraweak chemiluminescence have been able to demonstrate this effect, of psychological stress on the immune system, using saliva as a psychological stress marker. The impact of psychosocial factors on the oral mucosal lesions of individuals found that stress can contribute to weakened immunity and increased susceptibility to infection. Aim: To study the role of salivary peroxidase (SPOx) in psychologically stressed individuals with and without the presence of aphthous ulcer. Materials and Methods: The study involved evaluating subjects for stress, using Perceived Stress Scale. Depending on the stress scores and the presence or absence of oral aphthae, they were assigned into 3 groups of 30 each. After a thorough oral examination, individual samples of saliva was collected and subjected to microprotein estimation using a biochemical analyzer. Statistical Analysis Used: Analysis of variance (ANOVA) and Student′s t-test. Results: Decreased levels of peroxidase were found in individuals′ with aphthous ulcers, while the same was increased when no lesions were found and also on a lower stress scale. Conclusions: Our study analysis does show a variation in enzyme levels between the different groups highlighting the influence of stress on the peroxidase levels, which in turn when imbalanced, results in tissue damage, leading to aphthous formation.

Objective: We have undertaken a cross-sectional study to assess factors associated with dental pain that determine the expressed needs for dental care among 12-year-old school children in India. Materials and Methods: A total of 2 250 school children were surveyed after being drawn through stratified cluster random sampling. The simultaneous effects of sociodemographic characteristics, pain characteristics, and the impact of pain on the quality of life were studied in association with the expressed needs for dental treatment. Results: Among the studied school children, 71.4% suffered from dental pain, only 27.7% expressed need for dental healthcare. Socioeconomic status (SES) was a statistically significant determinant. Pain characteristics like the severity of pain and pain on eating hot and cold foods were significantly associated with expressed needs. Impact characteristics associated with expressed needs were embarrassment in showing teeth, brushing teeth, and difficulty in eating and drinking. Logistic regression analysis yielded a Nagelkerke R 2 value of 0.106. Conclusion: Important determinants of expressed needs for dental care among the studied population were SES, pain intensity, pain on thermal stimuli, impact characteristics like eating/drinking and embarrassment in showing teeth.

Background: Serum leptin concentrations are reported to be elevated in patients with periodontal diseases and may have a modulating role in cardiovascular diseases. Serum leptin concentrations have not been assessed in periodontitis associated with acute myocardial infarction (AMI) to date. The purpose of this study was to assess the concentration of serum leptin in periodontitis associated with AMI. Methods: A cross-sectional clinical study was conducted comprising a sample size of 120 participants divided into four groups (n = 30 each) based on their clinical signs: 1) control; 2) AMI; 3) generalized chronic periodontitis (GCP); and 4) GCP + AMI. Body mass index (BMI) was calculated and recorded for all the subjects based on BMI chart of the World Health Organization. After thorough clinical and oral examination, plaque index (PI), gingival index (GI), probing depth (PD), and clinical attachment loss (AL) were recorded. In addition, 2mL venous blood was collected by venipuncture from all participants to determine serum leptin concentration using the enzyme-linked immunosorbent assay method. Results: A strong correlation of serum leptin concentration to BMI was observed in AMI, GCP, and GCP + AMI groups. Serum leptin levels were significantly elevated in AMI, GCP, and GCP + AMI groups compared to the control group. Significant associations between serum leptin concentration and PI, GI, PD, and AL were also seen in the GCP group. PI, GI, PD, and AL were statistically significantly elevated in GCP + AMI and AMI groups. Conclusion: Elevated serum leptin concentration was associated with increased BMI, GCP, and AMI and may serve as a risk marker for these conditions.

Aims: The evaluation of clinical and specific microbiological changes associated with chlorhexidine chip in the chronic periodontitis patients. Materials and Methods: A total of 30 chronic periodontitis patients (aged 20-65 years) having pocket depth of =5 mm in molar teeth were selected and randomly divided into following treatment groups: Group 1 - Scaling and root planning (SRP), Group 2 - SRP along with chlorhexidine chip and Group 3 - Only chlorhexidine chip. The clinical and microbial parameters were recorded at baseline and 1 and 3 months post-treatment as above. Benzoyl-DL-arginine- naphthylamide (BANA) chair side test was used for estimation of specific microbiota. Results: Gingival index, probing pocket depth and clinical attachment level scores in selected teeth within the groups at different time intervals was significantly (P < 0.001) different. Although, the comparison between groups for specific microbiota in selected sites at different intervals was not statistically significant at baseline and 1 month, it reached statistical significance at 3rd month post-treatment. Although significant reductions in percentage of BANA positive sites were observed in all three groups, the Group 2 had significantly greater percentage of BANA negative sites. Conclusion: Local drug delivery using chlorhexidine chip enhances the benefit of SRP in the treatment of chronic periodontitis. © Journal of Natural Science, Biology and Medicine.

Objectives: The present study was undertaken to assess and compare the immunohistochemical expression of Bcl-2 in selected benign and malignant salivary gland tumors. Study Design: A total of 50 cases of buffered formalin-fixed, paraffin embedded tissues of previously diagnosed cases of benign and malignant salivary gland tumors from the archives of Department of Oral and Maxillofacial Pathology and Microbiology, SDM College of Dental Sciences and Hospital, Dharwad, India, were taken for the study. The immunohistochemical staining procedure was performed using monoclonal anti Bcl-2 antibody, as directed by the manufacturer. Results: Thirty six cases (72%) out of 50 cases showed a positive expression for Bcl-2. Benign salivary gland tumors showed a positive expression in 8 out of 14 cases (~57%) and malignant salivary gland tumors in 28 out of 36 cases (~78%). The staining was intense in the normal lymph node, which is used as a positive control. Bcl-2 expression was seen in both benign and in malignant salivary gland tumors taken for the study except in "canalicular adenoma". Conclusion: The immunohistochemical expression of Bcl-2 was greater and more intense in malignant salivary gland neoplasms, suggesting a high survival rate of tumor cells in malignant neoplasms. © Medicina Oral S.

Sympathetic ophthalmia (SO), also known as sympathetic uveitis, is a rare bilateral granulomatous panuveitis that occurs after a penetrating injury to an eye. After injuryfrom either surgery or accident, a variable period of time passes before a sightthreatening inflammation develops in both the eyes. The disease usually responds rapidly to corticosteroid therapy, but recalcitrant cases may require the addition of other immunosuppressive agents. A severely injured eye with no prognosis for vision should be enucleated within 2 weeks of injury to prevent SO. The purpose of this article is to highlight the risks of SO associated with the orbital fractures involving soft tissue components of the orbit. Though unusual, a maxillofacial surgeon, while operating on the orbital walls involving the soft tissue disruption, has to be aware of this condition so that the postoperative complications related to vision can be avoided. © 2012 Elsevier, Inc.

To describe the different patterns of the intraoral distribution of enamel fluorosis in permanent dentition. This cross-sectional analysis was conducted in Nalgonda district of Andhra Pradesh, India. A group of 1000 school children aged 13-15 years were selected by stratified cluster sampling from four different areas with different levels of naturally occurring fluoride in the drinking water. Fluorosis was recorded using the Thylstrup and Fejerskov index (TFI). The prevalence of fluorosis (TFI score >=1) was 100% at all four fluoride levels. This study revealed two patterns of fluorotic enamel changes in dentition. In high fluoride areas, incisors exhibited lower TFI values than canines, premolars and molars, with the maximum affected being second molars followed by first molars. In low fluoride areas, a steeper profile of dental fluorosis, starting from incisors and first molars through canine and premolars to second molars, was noticed. With the exception of permanent second molars and permanent first molars in high fluoride communities, the intraoral distribution of different degrees of dental fluorosis was related to the completion of primary enamel formation.
