“…In a Chilean study also, the maxillary third molars reached all the stages of development much earlier than the mandibular third molar. [ 23 ] This result is in accordance with a study of the Danish population. But the Danish study scored the developmental stages of the third molar according to the Köhler modification of the 10-stage method of Gleiser and Hunt.…”

Context: Age estimation is one of the prime requisites in forensic human identification cases and the criminal justice system. There are several age estimation methods using dental parameters. A method proposed by Mincer et al. which uses the mineralization stages of third molars based on Demirjian’s developmental stages is less tested in the Indian population. Aim: The present study aimed to assess the developmental status of the third molars and to apply and validate Mincer et al.’s method on the Western India population. Methods and Material: A total of 306 orthopantomograms (OPGs) from 128 males and 178 females with a mean age of 16.89 years ± 3.68 were analysed. Demirjian’s A-H staging was applied to record the developmental stages of 1100 third molars. Mincer et al.’s mean age of attainment was applied based on the American Whites (Caucasian) population for males and females separately using stages of #18 and #38. Results: There was a slight overestimation of the chronological age (CA) in both #18 and #38. The females showed more accurate estimated age (EA) than males. Conclusions: Mincer et al.’s method is a convenient age estimation method using the third molar’s developmental stage. The mean age of attainment mentioned in the original Mincer et al.’s study can be used in the Western Indian population, with a residual value ranging from 0.21 to 0.25 years.
