Aims and Objectives:The aims and objectives of the study were to compare the accuracy of bite mark analysis from three different food substances-apple, cheese and chocolate using two techniques-the manual docking procedure and computer assisted overlay generation technique and to compare the accuracy of the two techniques for bite mark analysis on food substances.Materials and Methods:The individuals who participated in the study were made to bite on three food substances-apple, cheese, and chocolate. Dentate individuals were included in the study. Edentulous individuals and individuals having a missing anterior tooth were excluded from the study. The dental casts of the individual were applied to the positive cast of the bitten food substance to determine docking or matching. Then, computer generated overlays were compared with bite mark pattern on the foodstuff.Results:The results were tabulated and the comparison of bite mark analysis on the three different food substances was analyzed by Kruskall-Wallis ANOVA test and the comparison of the two techniques was analyzed by Spearman's Rho correlation coefficient.Conclusion:On comparing the bite marks analysis from the three food substances-apple, cheese and chocolate, the accuracy was found to be greater for chocolate and cheese than apple.

Background: Oil pulling is an oral hygiene practice and is described in the ancient Ayurvedic literature. Materials and Methods: A total of 30 subjects with plaque related mild -moderate gingivitis in the age Group of 18-25 was recruited and they were divided into two Groups as Group A and B, each with 15 subjects. Group A subjects were advised to practice coconut oil pulling therapy and Group B subjects were advised to use Chlorhexidine Gluconate 0.12% solution for 4 weeks as an adjuvant practice along with routine tooth brushing. Estimation of salivary Aspartate Aminotransferase was done at pre and post intervention stage for both the study Groups by using semi auto analyser. Results: Statistically significant reduction in the reduction in the salivary Aspartate Aminotransferase level was seen at post intervention stage in Group A and Group B compared to preintervention stage. Comparison of salivary Aspartate Aminotransferase level between Group A subjects and Group B subjects at pre and post intervention stage revealed no significant difference. Our study results show that oil pulling utilizing coconut oil is effective in reducing the severity of plaque induced mild-moderate gingivitis and the effect is comparable to 0.12% chlorhexidine mouthwash in reducing plaque formation and gingivitis. Conclusion: Oil pulling utilizing coconut oil is an effective adjuvant oral hygiene practice in reducing the severity of plaque induced mild -moderate gingivitis along with the routine oral hygiene measure. Coconut oil pulling practice could be a potential alternative to chlorhexidine mouth wash for long term use.
