Tooth formation is widely used to assess maturity and predict age. Within clinical dentistry this formation aids in diagnosis and treatment planning. Chronological age, as recorded by registration of birth date, is referred to throughout an individual’s life. This information is relevant in medical and dental practice for evaluating developmental progress, for educational purposes, and in legal matters, particularly in the application of criminal law. The panoramic radiographs of 75 healthy children (40 boys and 35 girls) aged between 5-14 years were selected. Demirjian, Nolla, Haavikko, Williams and Cameriere methods were applied for estimation of age. The result of our study have shown that Williams method is more accurate followed by Haavikko, Cameriere, Nolla and lastly Demirjian method.

Our research is based on the confrontation of modifications of Gustafson’s aging method with the aims of producing of up to date. Identification tables for practical forensic dentistry. The identification tables were produced using the mutual relationship of sum of point values such as the secondary dentine, the secondary cementum , transparency and age.

Keywords: Teeth, estimation of age, identification tables, regression equation.

Background: Bite marks may be one of the physical and biological evidences left by criminals at the site of criminal act. Bite mark identification is based on the individuality of a dentition, which is used to match a bite mark to a suspected perpetrator., Aims & objectives: To formulate an integrated technique for analyzing the bite marks by devising an experimental case study using new and accepted techniques., Methodology: Dental stone casts and VPS impressions of bite marks on wax wafers were made for thirty volunteers having complete set of natural upper and lower anterior teeth. Pattern association followed by metric analysis of selected dental features in the dental stone casts and VPS impressions was done., Results: A high sensitivity 0f 100% and positive predictive accuracy of 66.6 % implies a fairly high degree of accuracy for this method of bite marks analysis., Conclusion: This paper describes an objective analysis technique which could be used when confronted with a bite mark case and can be adapted for each individual case. The relevant frequency of specific dental features within specified populations is, however, required.

Age estimation in children is important in clinical as well as forensic dentistry. The orthopantomograph samples of 50 healthy children (25boys: 25girls) aged between 5-15 years was selected and Cameriere regression equation was applied. We observed underestimation of estimated age in boys and overestimation in girls as compared to their chronological age.

Histological study was conducted on 82 subjects of both sexes (Male 41 Female 41) from the compact portion of mandible to determine age by BR Equation. In majority of the cases it was observed that the low (2-6 years) as compared to actual age.
