Inadequate knowledge along with the persisting myths regarding the etiology, course and outcome of oral diseases makes it difficult to initiate health behavioural changes. Present study scrutinizes various myths and misconceptions regarding oral health among the outpatients. The aim of this study was to assess myths and misconceptions about oral health and imparting education regarding the same. Material and Methods: The calculated sample size was 200. A pre –tested closed ended questionnaire was prepared in both English and local language (Kannada). It comprised of four sections with 24 questions. The Content validity index value of 0.9 suggested a good validity. A Chi square test was applied and significance level was fixed at p< 0.05. Results: We had 100% response rate. In our study half of the participants visited dental hospital for the very first ti...

Ces compteurs sont connectes aux serveurs via des supports de communication. L'application de communication peut communiquer de facon bidirectionnelle en temps reel entre les compteurs et les serveurs via les supports de communication. L'application de communication peut determiner les parametres de configuration reels selon lesquels le compteur fonctionne a tout moment. Aux fins de detecter un vol de consommation, l'application de communication peut comparer les parametres de configuration reels avec les parametres de configuration par defaut.

Materials and Methods: This was an observational, descriptive, cross-sectional survey. Ninety-one 2nd year dental students completed two consecutive preclinical examinations on ideal teeth arrangement and two self-assessments. Self-assessment was done using a validated, structured, self-designed questionnaire named “prosthetic denture setup–self assessment questionnaire.” The examinations involved artificial teeth arrangement in Class I jaw relation on maxillary and mandibular ideal edentulous casts mounted on a mean value articulator simulating the clinical procedure of a complete denture patient. Students' and their instructor's assessments were evaluated separately, and statistical results were obtained using t-test and Pearson's product moment correlation coefficient test. Regression analysis was ...

Materials and methods: Subjects with OPMDs (n = 60) were randomized to receive green tea extract [topical + systemic (800 mg/day)] or curcumin [topical + Systemic (950 mg/day)] or a combination therapy with 20 patients in each group for 3 months. Biomarkers (Ki67, cyclin D1, and p53) were evaluated in baseline and 12-week biopsies. Results: The clinical response rate observed in OPMDs was higher in the combination group (n = 13; 65%) as compared to the curcumin (n = 11; 55%) and the green tea extract group (n = 7; 35%) and was statistically highly significant. Treatment medications also improved histological grades, although not statistically significant. All the study drugs were well tolerated by patients and did not raise any safety concerns. There was statistically significant (p < 0.01) downregulation of p53, Ki67, and cyclin D1 expression at 3 months as compared to baseline in the combination group. Conclusion: Treatment of OPMDs with curcumin and green tea extract combination demonstrated a significant clinical response supported by downregulation of molecular biomarkers in the short-term (12 weeks). The present results warrant a long-term clinical testing of green tea and curcumin combination for oral cancer prevention. Clinical significance: Chemoprevention is a promising treatment strategy to reverse, stabilize, or arrest progression of these OPMDs. Use of natural dietary agents like green tea and curcumin, which are readily available, have low toxicity, and more importantly demonstrate a synergistic effect, is an attractive alternative in the chemoprevention of oral cancer. The assessment of biomarkers has helped us to understand the mechanism of action of these chemopreventive agents.

Materials and methods: This cross-sectional survey was conducted with 900 school children aged between 12 and 15. The subjects were randomly selected from six high schools. Selected subjects completed a survey instrument predesigned to measure subjective oral health indicators including the eight-item OIDP frequency scores. The study participants were clinically examined for dental caries, and they completed a self-administered questionnaire about demographic information and oral behaviours. Results: 44% of the students reported at least one oral impact in the previous 6 months. The reliability of the instrument was measured in terms of Cronbach's alpha for the OIDP frequency. It was found to be 0.81. Eating was the most common performance affected (33%) followed by cleaning teeth (22%) and speaking (20%). The severity of impacts was low for relaxing and carrying out works. Conclusion: The OIDP frequency score has acceptable psychometric properties in the context of an oral health survey among high school children of Davanagere city, Karnataka, India.
