A Comparative Study Of Age Estimation Methods In Forensic Odontology

Abstract

Aim: The purpose of the research was to assess the Demirjian method's applicability and compare it to Indian methods for estimating dental age in participants enrolled in an Indian dentistry school.Materials and Methods: The research comprised 250 participants, 130 boys, and 120 females, aged 7 to 18 years, who had orthopantomography. The subject's chronological age was reported using their birthdate. Utilizing Demirjian's and Indian formulae, dental age was calculated. The collected data was all placed into a spreadsheet and put through statistical analysis.Results: The research sample's mean chronological age was 12.39 ± 3.32 years, whereas the mean ages determined using Demirjian's approach and the regression formula customized for India were 11.56 ± 3.17 years and 14.20 ± 3.24 years, respectively. Demirjian's technique in this research underestimated dental age in men by 0.84 years and in females by 0.83 years (P 0.05). Males' dental ages were overestimated by 1.72 years and females' dental ages by 1.91 years using Indian-specific regression formulae (P < 0.05).Conclusion: The published regression methods for Demirjian and India are not appropriate for the current research group. Therefore, cubic regression formulae for boys and females in the Indian population were created.
