Hence, a study was conducted in dental colleges of Davanagere city among postgraduate students with the aim to assess their knowledge and attitude towards oral and peri-oral piercing.Methods: Across-sectional survey involved 212 dental postgraduate students of dental colleges in Davanagere city who consented to participate. A pretested, validated, self-administered questionnaire containing 15 multiple-choice items assessing the postgraduate students’ knowledge and attitude towards oral and peri-oral piercing practices was used for data collection. Data was presented in the form of frequencies and percentages.Results: Participants had fair knowledge regarding oral and perioral piercing. Majority of participants (75%) felt oral and peri-oral piercing practices as a sign of style /fashion statement. Around 45-50% felt tongue piercing and nose piercing (66%) as most preval...

Aim: The aim of this study is to assess the usage of social media and its influence on clinical practice among dental faculty members of dental colleges in Davangere city. Materials and Methods: Descriptive cross-sectional survey was carried out among the convenience sample of 88 dental faculty members of two dental colleges in Davangere city. An investigator-designed questionnaire comprising 15 close-ended questions related to the usage and various aspects of the influence of social media was used as a tool in the present survey. Ethical clearance was obtained from Institutional Review Board of Ethics committee of college. Descriptive statistics were generated regarding frequencies and percentages. Results: Among the ...

Research paper thumbnail of Antibacterial effect of amorphous calcium phosphate-casein phosphopeptide varnish against Streptococcus mutans: An exploratory in vivo randomized controlled trial

Aim of study was to evaluate and compare the antimicrobial property of sodium fluoride varnish reinforced with amorphous calcium phosphate-casein phosphopeptide and tricalcium phosphate against streptococcus mutans. Methods: In the clinical setting, trial was conducted involving 18, 14-15 year old school children, randomly allocated into three interventional groups, Group A (5% Sodium fluoride varnish, Fluoritop-SR varnish), Group B (5% Sodium fluoride-Tricalcium phosphate varnish, Clinpro White varnish) and Group C (5% Sodium fluoride-amorphous calcium phosphate-casein phosphopeptide varnish, MI Varnish) to receive the varnish application. Saliva samples were collected at the end of one hour after varnish application for S Mutans count estimation. Student's paired 't' test and One way-ANOVA tests were used for statistical analyses. Results: Significant reductions in salivary streptococcus mutans count at one hour was achieved with application of B & C varnishes compared to varnish A. Conclusion: amorphous calcium phosphate-casein phosphopeptide and tricalcium phosphate varnish groups exhibited better antimicrobial property against streptococcus mutans compared to Sodium fluoride varnish at one-hour post intervention.

The higher incidence of the degloving injuries of mandible are seen in children and young adults due to higher involvement in contact sports. In elders, degloving injury of mandible are rare as compared to that of the limbs which are common. Here, we describe the case report of an elderly female with an apparent soft tissue abrasion with encrustation along the left side of the lower lip due to fall. Thorough intra oral examination revealed the presence of degloving injury along the lower anterior region of mandible which was debrided and sutured. Without a high level of suspicion, such lesions existing in the gingivobuccal sulcus may be missed, leading to increased risk of secondary infection and obligate healing in turn leading to increased morbidity.

A questionnaire with close-ended questions on eight scenarios was administered to the 135 study participants. In the case of scenario 1, 81.4% of the participants said that the doctor had violated the principle of truthfulness. As for scenario 2, less than 50% of the participants replied that the doctor had breached ethical principles. In case scenario 3, 93% felt that the doctor should have taken the physician's opinion before extracting a tooth. Most dental practitioners faced ethical dilemmas because of the lack of awareness, and there is a need to introduce certain programmes to promote knowledge of ethics.
