Estimating the chronological age of humans is a prevalent need in forensic practice. Comparing accuracy different identification methods helps provide most reliable method for specific population. This study aimed to compare assessments using skeletal maturation and dental mineralization sample Egyptians assess if combining both yields more precise prediction. A cross-sectional included 176 Egyptian children adolescents aged between 8 16 who underwent orthopantomograms hand-wrist radiographs. All radiographs were scored independently Fishman development Nolla method. While valid predictors with variable sex group Egyptians, showed superior performance. The slightly underestimated age, while over-estimated it, showing median differences -0.21 0.17, respectively. Correlating estimated intraclass correlation coefficients (0.854 0.660) (0.973 0.977) females males, respectively (P < 0.001). model adopting score exhibited highest R² 0.968) lowest Akaike information criteria (96 106) respectively, which comparable scores indicators. Therefore, we recommend incorporating only estimation without further hand wrist radiography.
