ABSTRACT

Introduction: Data in the form of age, gender, and blood group might provide vital clues in human identity through odontological examinations. Therefore it is important to gather as much data as possible using less tissue. The purpose of this study was to find out whether a tooth helpful in determine age, gender and ABO blood group of individual or not?. Materials and Methods: The study sample consisted of twenty eight teeth divided into four groups under different environmental conditions and time. The teeth were sectioned longitudinally in the buccolingual plane along the midline. Longitudinal ground sections of each tooth were prepared for age determination from cemental lines. Pulp removed was divided into two halves thereafter sex and blood group was determined. Results: A strong positive correlation was found between the estimated age and actual age of the study groups. Moreover, there was no significant difference between the actual and determined sex and blood group of the study groups. Conclusion: Although age, sex, and blood group are more reliably determined in freshly extracted teeth, these variables may be of significant help in identification even after a period of 6 weeks postextraction.
