Introduction: Stress can increase the susceptibility to dental caries by four possible mechanisms. Studies show that adolescents tend to more likely develop negative body image, disturbed eating behaviours and high levels of stress. Students report stress, taking and studying for exams being the greatest source of academic stress due to competition and the large amount of content in less time.Aims and Objectives: The objectives were to analyze the caries experience in relation to perceived stress during preuniversity examination period, to estimate the prevalence of dental caries and to calculate SiC (significant caries index) among preuniversity students in Marathahalli, Bangalore city, India.Materials and Methods: This cross-sectional, correlational study involved 210 students (Response rate = 65.37%). The questionnaire consisted of demographic details and Perceived Stress Scale (PSS). Dental caries status was evaluated using the WHO (1997) caries diagnostic criteria for decayed, missing, and filled teeth (DMFT: Dynamical mean field theory).Results: Prevalence of dental caries was 50.48%. Mean DMFT was 1.74 and Sic index was 4.56. The correlation between PSS and caries experience was found to be weak (r=0.389) (p<0.001).Conclusion: Academic stress appears to affect oral health, shown by higher caries experience in high perceived stress score individuals. © 2014, Journal of Clinical and Diagnostic Research.All Rights Reserved.

Introduction: Role of dentists in prevention and sustainable care of leprosy is known. Changing leprosy scenario has led to requirement of change in leprosy education. However, knowledge and attitude of dental students on leprosy remains unknown. Aim: Hence a study was conducted to assess knowledge and attitude of dental students about Leprosy. Materials and Methods: A questionnaire based, cross-sectional survey was conducted among 350 undergraduate and the postgraduate dental students of two dental colleges in Faridabad, India. The score for knowledge ranged from 0 to 16 and scores for attitude ranged from 0 to 26. These scores were further coded as poor, fair and good. Results: Mean knowledge score for the sample was 7.64±3.23. A total of 32.29% participants were under poor knowledge category; 57.42% had fair knowledge about Leprosy while 10.29% had good knowledge. Mean attitude score was 15.5 ± 5.98. A total of 30.57% had poor attitude scores, 42.57% had fair scores while 26.86% had good attitude scores. Univariate analysis showed year of training to be a significant predictor for knowledge level (t=7.12; p<0.001). Conclusion: The results indicate need for three important changes towards Leprosy in Dentistry. These changes are need for incorporation of leprosy education in Dentistry, need for incorporation of problem based as well as evidence based learning in Dentistry integrated with general health and need for reestablishing public health programs for Leprosy utilizing dental workforce. © 2016, Journal of Clinical and Diagnostic Research.

Science is a dynamic subject and it was never free of misconduct or bad research. Indeed, the scientific method itself is intended to overcome mistakes and misdeeds. So, we aimed to assess various factors associated with retraction of scientific articles from 2004 to 2013. Data were retrieved from PubMed and Medline using the keywords retraction of articles, retraction notice, and withdrawal of article in April 2014 to detect articles retracted from 2004 to 2013. Statistical analysis was carried out using t-test and Karl Pearson's correlation coefficient. Results showed that a total of 2343 articles were retracted between 2004 and 2013, and original articles followed by case reports constituted major part of it. Time interval between submission and retraction of article has reduced in recent times. Impact factor and retraction do not have any significant correlation. We conclude that although retraction of articles is a rare event, its constant rise in scientific literature is quite worrisome. It is still unclear whether misconduct/mistakes in articles are increasing hastily or the articles are retracted at a rapid rate in recent times. So, it should be considered as an urgent issue and it is the responsibility of journal editors to track misconduct by following Committee on Publication Ethics (COPE) guidelines and making an effective strategy.

Impacted teeth are those with a delayed eruption time or that are not expected to erupt completely based on clinical and radiographic assessment. The third molars can vary considerably in size; contour and relative position to the other teeth. Mandibular third molars were more often impacted as compared to the maxillary third molars. The mandibular third molars are the most frequently impacted teeth that can be found in humans. Data analysis shows that the prevalence of third molar impaction ranges from 16.7% to 68.6%. Impacted teeth are often associated with pericoronitis, periodontitis, cystic lesions, neoplasm, root resorption and can cause detrimental effects on adjacent tooth. © 2010 RJPBCS. Source

Oral submucous fibrosis (OSMF) is an insidious chronic disease that is associated with significant functional morbidity and an increased risk for malignancy. It initially affects the lamina propria of the oral mucosa, and, as the disease progresses, it involves the submucosa and deeper tissue, including muscles of the oral cavity, resulting in loss of fibroelasticity. OSMF is a pre-malignant condition mainly caused by areca nut chewing. The aim of this study was to find out the involvement of muscles of mastication and facial expression in patients with OSMF by assessing the cross-sectional thickness and activity of the masseter, anterior temporalis and orbicularis oris muscles by ultrasonography and electromyography and comparing with healthy controls and also to find out any correlation between the ultrasonographic cross-sectional thicknesses of the masseter, anterior temporalis and orbicularis oris muscles with electromyographic activity. Methods: 40 patients with OSMF were included in the study group, and the patients were divided into four groups on the basis of interincisal mouth opening, i.e. Group I (mouth opening >35 mm), Group II (mouth opening between 30 and 35 mm), Group III (mouth opening between 20 and 30 mm) and Group IV (mouth opening <20 mm). Ultrasonographic cross-sectional thickness and electromyographic activity (amplitude and duration) of the masseter, anterior temporalis and orbicualris oris muscles were recorded in patients with OSMF and 20 controls. Intergroup comparison of ultrasonographic cross-sectional thickness and activity (amplitude and duration) was done, and Pearson's correlation coefficient was applied to find out any relation between ultrasonographic and electromyographic findings. Results: Thickness and activity of the masseter muscle was significantly reduced in Group IV (mouth opening ,20 mm) when compared with the control group. The anterior temporalis and orbicularis oris muscles remained unaffected. A positive correlation was observed between the thicknesses of the masseter muscle and the amplitude in Groups I, II and III; the anterior temporalis muscle in Group II and the control group; and the orbicularis oris muscle in Groups II, III and IV. Conclusions: It was concluded that, among the muscles studied, there was an early involvement of the masseter muscle in patients with OSMF compared with that of other muscles. © 2014 The Authors.
