Abstract :Purpose: Dental age assessment is one of the most reliable methods of chronological age estimation used for criminal, forensic and anthropologic purposes. This study aimed to determine how accurate it was to estimate the chronological age by looking at the dental age measured with the Nolla and Demirjian methods in a Turkish sample, based on the variables of gender and age-group. Materials and Methods: A retrospective study was performed on panoramic radiographs of 1587 subjects insert ignore into journalissuearticles values(774 females and 813 males);, aged 3–17 years. The mean dental age according to the Demirjian and Nolla methods were compared to the mean chronological age insert ignore into journalissuearticles values(CA);. Also, the percentage value of prediction of CA was determined by using the both methods. Results: An under-estimation of the chronological age was observed by using Nolla’s method insert ignore into journalissuearticles values(males -0.003, females -0.32, both -0.16); and an over-estimation of the dental age was observed by using Demirjian’s method insert ignore into journalissuearticles values(males 0.61, females 0.75, both 0.68);. Conclusion: Nolla’s method was more accurate in the CA estimation than Demirjian’s method in Eastern Turkish population.
