Are Tooth Prints a Hard Tissue Equivalence of Finger Print in Mass Disaster: A Rationalized Review.

Personal identification methods may not be efficient when bodies are decomposed, burned, in cases of mass disasters when soft tissue cannot provide reliable information or has been lost. Various methods currently employed in forensic odontology for personal identification include comparing with antemortem dental charts, rugoscopy, denture labeling, DNA analysis from dental pulp, bite mark analysis, etc., Recently, there is growing interest in the study of enamel rod end patterns. These enamel rod end patterns are termed as "Tooth prints" and the study of these prints is known as "Ameloglyphics" (amelo: Enamel, Glyphics: Carvings). This review encompasses about the basis of using enamel rod end patterns, methods of obtaining the patterns and further suggests these tooth prints as an analogy to finger print in personal identification in mass disasters.

Prevalence of Tooth Shade and its Correlation with Skin Colour - A Cross-sectional Study.

INTRODUCTION: Aesthetics has become an important issue in modern society. Tooth shade is one of the factors in determining aesthetics. Studies have revealed that tooth shade is influenced by age, gender, eye colour, skin colour and other factors. AIM: The present study was aimed to assess the prevalence of tooth shade and its correlation with skin colour. MATERIALS AND METHODS: A total of 300 subjects aged 18-20 years were evaluated for tooth shade using Vitapan - 3D shade guide. Anterior teeth were checked under natural light and facial skin colour by Lakme liquid foundation make up as a shade guide. Data was analysed using chi square test and spearman's correlation. RESULTS: Out of 300 students, 114 (38.00%) had A2 tooth shade; the least prevalent tooth shade among Chitradurga population was C1 (4.00%). There was a positive correlation between tooth shade and skin colour which was found to be statistically significant (p <0.05). CONCLUSION: The most prevalent tooth shade among Chitradurga population was A2 and least was C1. There was a significant correlation between tooth shade and skin colour with lighter skin tone subjects having lighter tooth shade hence skin colour can be used as a guide for shade selection.

Evaluation of pain in single and multi rooted teeth treated in single visit endodontic therapy.

BACKGROUND: The incidence of post-operative pain was compared following single-visit canal treatment in single- and multi-rooted teeth, with and without periapical radiolucency. The article also reviews the issues of postoperative pain and healing, following single-visit and multi-visit endodontic therapy. Single-visit endodontic therapy (SVE) was performed in 50 single-rooted teeth and 60 multiple-rooted teeth. MATERIALS & METHODS: Single-visit endodontic therapy (SVE) was performed in 50 single-rooted teeth and 60 multiple-rooted teeth. The subjects were divided as follows: Group I -Single-rooted teeth with periapical radiolucency (n=25); Group II-Single-rooted teeth without periapical radiolucency (n=25); Group III-Multiple-rooted teeth with periapical radiolucency (n=30); and Group IV-Multiple-rooted teeth without periapical radiolucency (n=30). Assessment of postoperative pain was done at 24hrs, 3 days and 1 week using a self report questionnaire. The data was analyzed using non-parametric Kruskal -Wallis test. RESULTS: No statistically significant difference was observed in postoperative pain following SVE between the single-rooted and multiple-rooted teeth groups at 24hrs, 3 days and 1 week. The presence or absence of periapical radiolucency had no significant influence on the incidence of reported postoperative pain following SVE. CONCLUSION: There was no difference in incidence of pain in single rooted teeth and multi-rooted teeth with and without periapical radiolucencies following SVE. Thus, incidence of post-operative pain does not seem to be a valid comparison criterion between single- and multiple-visit endodontic therapies. Also, the literature suggests similar success rates with single-visit and multiple-visit root canal treatment.
