Aim: To determine the age of Juvenile patients based on Third Molar Development in population belonging to Namakkal district for Forensic application. Methodology: The data was collected from the Orthopantamograms (OPG) which was regularly taken for different purposes in K.S.R institute of Dental Science & Research Outpatient Department. A retrospective analysis of these OPG's was conducted for different developmental stages given by Dimerjian et al. in 1973 for the age group of 14 to 25 years. SPSS version 10.0 was used for statistical analysis. Results: Mean Ages of the juveniles were calculated using the developmental stages of the Third molar and it was found that there was significant variation between the mean ages for different developmental stages. This implies that there exists definite ethnic variation in development of Third Molar and thus their mean ages also. Discussion: The described data may provide the third molar developmental stages and its mean age of the calcification for people belonging to Namakkal district only. Further researches are warranted in other populations as Third molar development shows definite ethnic variations, which is evident from the present study. Hence this could be used as a tool for age identification in forensic odontology for a sub group of Indian Population.
