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.
