Abstract

Background: Several methods relying on dental calcification of the teeth, up to the second molar, are used for evaluation of age in childhood. The objective of this research was to evaluate the reliability and validity of Demirjian\'s and Cameriere\'s radiographic methods of dental age estimation in Puducherry population aged between 9 and 13 years. Aim: The purpose of this study was to evaluate the accuracy of Demirjian and Cameriere methods for dental age estimation in order to obtain a more reliable and reproducible age estimation method as an aid in forensic odontology. Settings and Design: The sample was comprised of 200 digital OPG of children in and around Puducherry (90 female and 110 male) aged 9 to 13 years. Method: Demirjian & Cameriere method, both are assessed by the dental maturity of seven left mandibular teeth. The mean age error and absolute age error for both the methods were calculated and the difference between the estimated dental age and chronological age were compared with the paired t–test. Results: The Demirjian method tends to overestimate (1.10 years) the chronological age of participants and Cameriere method underestimated (-0.31 years) the chronological age. On gender comparison, boys and girls showed overestimation by 0.99 years and 1.22 years for Demirjian methods respectively, while underestimation by -0.30 years and -0.33 years for boys and girls respectively was observed with Cameriere method. Conclusions: Cameriere method of dental age estimation is more accurate than Demirjian method for estimating the age among 9 – 13 year old in Puducherry population.
