Forensic age estimation using foti’s method– A radiographic study

Abstract

Introduction: Foti et al. proposed four mathematical models to determine the age by counting the erupted teeth and germs in children, obtained with the help of stepwise ascending multiple linear regressions. Among the four models, Model 1 regressive formula helps to determine the age by using radiographs that shows teeth and dental germs. The present study was conducted to evaluate the efficacy of Foti’s method of dental age estimation by comparing the age estimated with the chronological age in the study population. Materials and Method: A retrospective study has been conducted using 62 panoramic radiographs of subjects ranging from the age 6-20 years. The age estimation is done by Foti’s Model No. 1 regressive equation using radiographs showing erupted teeth and dental germs. Results: Statistical analysis indicated that there is signi?cant difference between chronological age and age obtained by Foti’s method (p-value over estimation of age when Foti’s model 1 regression formula is used in the present study population. Conclusion: The present study indicates that Foti’s Model 1 regression formula is inappropriate for age estimation in the present study population.
