AIM
This study compared the effectiveness of the three-dimensional (3D) cone beam computed tomography (CBCT) method of age estimation developed by Asif et al. with two-dimensional Cameriere's method.
SUBJECTS AND METHODS
CBCT images belonging to 129 Malaysian Chinese and Malay ethnic groups aged 7-14 years were investigated and analysed.
RESULTS
The results indicated a strong correlation between chronological age and the predictor variables for both Cameriere's ( = 0.984) and Asif's ( = 0.988) methods of age estimation. Fisher Z test analysis indicated no statistically significant difference in the correlation values between the two methods. Mean absolute error (MAE) value of 0.613 was observed for Cameriere's and 0.290 was observed for Asif's method.
CONCLUSIONS
The results indicated that the methods of age estimation from both Asif et al. and Cameriere et al. are applicable on Malaysian children. However, Asif et al.'s 3D CBCT method of age estimation resulted in greater accuracy and reliability in estimating chronological age.
目的
本研究比较了 Asif 等人开发的三维（3D）锥形束计算机断层扫描（CBCT）法和二维卡梅里耶（Cameriere）法在年龄估计方面的有效性。
受试者和方法
对 129 名 7-14 岁的马来西亚华裔和马来族的 CBCT 图像进行了研究和分析。
结果
结果表明，Cameriere（ = 0.984）和 Asif（ = 0.988）的年龄估计方法的预测变量与实际年龄之间存在很强的相关性。Fisher Z 检验分析表明，两种方法的相关值之间没有统计学上的显著差异。Cameriere 法的平均绝对误差（MAE）值为 0.613，Asif 法的 MAE 值为 0.290。
结论
结果表明，Asif 等人和 Cameriere 等人的年龄估计方法均适用于马来西亚儿童。然而，Asif 等人的 3D CBCT 年龄估计方法在估计实际年龄方面具有更高的准确性和可靠性。
