Abstract

Introduction: Age estimation using dental findings has an important role in identification of an individual in forensics but its utilization is not well established. This study has been done to estimate the age using third molar in dental radiographs. Aim: To estimate the chronological age based on the eight stages of third molar development method by Demirjian et al. in Indian population and compare third molar development with age and between sex. Materials and Method: 294 digital panoramic radiographs of Indian population aged 7 to 25 years are retrospectively enroled and their Demirjian’s stages are recorded. Statistical analysis to determine comparison between the chronological age and age estimated using demirjian method are done. Results: Statistically significant difference were obtained in maxilla and mandible on both the sides in all the age groups which was revealing a decreasing trend as the age progresses. The age estimation using Demirjian method was almost same as the chronological age in group 16 to 20 years. Conclusion: Third molar development can be a useful tool in age estimation of an individual in disasters, catastrophes and for medico-legal purposes.
