Compatibility Of Nolla and Demirjian Methods for Children Living in Eastern Türkiye
Özet
Objective: Dental age serves as a critical metric in determining the biological age of individuals and
is frequently utilized in forensic and clinical research. The present study aimed to evaluate the
implementation and accuracy of Nolla and Demirjian methods in assessing dental development
among 6-year-old children residing in the eastern region of Türkiye, specifically focusing on
dentition of the left mandibular region.
Methods: The orthopantomographic radiographs from 190 patients (104 males, 86 females)
chronologically aged 6 years, who presented to the Department of Pedodontics, Faculty of Dentistry,
Atatürk University, for examination between January 1, 2024, and May 31, 2024, were analyzed. The
teeth in the left mandibular region were individually classified according to the calcification stages
described by Nolla and Demirjian. The obtained data were statistically analyzed using Pearson’s ChiSquare test and Wilcoxon test, with a significance level set at p<0.05.
Results: Age estimations performed using Nolla and Demirjian methods revealed differences of 0.81
± 0.49 years and 0.27 ± 0.51 years, respectively (p<0.05). Additionally, low but statistically significant
correlations were identified (p<0.001). Weaker correlations between the age estimation methods
were observed in males, while stronger and statistically significant correlations were found among
females. Demirjian method was determined to be more consistent compared to Nolla method for
both genders.
Conclusion: The accuracy of age estimation methods may vary based on gender, highlighting
potential differences in biological age assessment techniques across sexes. These results emphasize
the importance of gender-specific evaluations when using dental development-based age
estimation methods.
