Abstract:  The aim of this study was to investigate whether or not the Nolla method is appropriate for Turkish children for the determination of the dental age (DA). A group of 719 children between the ages of 6 and 18 years were included in the study. DAs from orthopantograms by the Nolla method were estimated. The results obtained were compared with chronologic age (CA). Paired t and the Wilcoxon tests were performed. Both genders were underestimated in dental maturity when compared with the reference samples in total (−0.3 years) (p < 0.01). The differences in girls were statistically significant in total and in all groups except for 7–7.9. The differences in boys between the CAs and DAs were not statistically significant in total and in all groups except for 7–7.9 and 8–8.9. Although the accuracy of this method was suitable for boys, according to our findings, it was not suitable for girls.
