Age estimation plays a significant role in forensic science, archeology, pediatric endocrinology and clinical dentistry. Tooth development is a reliable pathway for age estimation, especially in children. The aim of this study was to evaluate the accuracy of the Demirjian method (DM), Willems method (WM) and Cameriere method (CM).
This study included panaramic radiographs of 330 individuals (165 girls, 165 boys) aged between 5 and 15.90 years. The differences between chronological age (CA) and the estimated dental age (DA) were statistically tested using a paired sample t-test and the Wilcoxon signed rank test.
The mean prediction error showed that; the DM overestimated the DA by 0.304 years, the WM underestimated the DA by -0.060 years and the CM underestimated the DA by -0.580 years. The difference between CA and estimated DA was not statistically significant according to WM (p = 0.074) and statistically significant according to DM and CM (p < 0.001).
In conclusion, this study indicated that WM determines DA satisfactorily in a Turkish subpopulation.
年龄估计在法医学、考古学、儿科内分泌学和临床牙科中发挥着重要作用。牙齿发育是年龄估计的可靠途径，尤其是在儿童中。本研究的目的是评估德米尔坚方法（DM）、威廉姆斯方法（WM）和卡梅里埃方法（CM）的准确性。
本研究纳入了330名年龄在5至15.90岁之间的个体（165名女孩，165名男孩）的全景X线片。使用配对样本t检验和威尔科克森符号秩检验对实际年龄（CA）与估计牙齿年龄（DA）之间的差异进行统计学检验。
平均预测误差显示；DM将DA高估了0.304岁，WM将DA低估了-0.060岁，CM将DA低估了-0.580岁。根据WM，CA与估计DA之间的差异无统计学意义（p = 0.074），而根据DM和CM有统计学意义（p < 0.001）。
总之，本研究表明WM在土耳其亚人群中能令人满意地确定DA。
