The evaluation of two radiographic methods for age determination of children in an Indian population

Abstract

The aim of the present study was to evaluate the applicability of the methods proposed by Nolla7 and Nicodemo9 for estimation of dental age and its correction with chronological age. Orthopantograms of 413 patients, aged 6-16 year (70-195 months) were selected to estimate the correlation between dental and chronological age. With both the Nolla and Nicodemo methods, the estimated age was lower than compared to chronological age except for the Nolla method in girls. There were significant correlations between chronological and estimated dental age (by Nolla and Nicodemo methods) in both genders.
