The aim of this study was to evaluate applicability of five dental methods including Demirjian's original, revised, four teeth, and alternate four teeth methods and Willems method for age estimation in a sample of Turkish children. Panoramic radiographs of 799 children (412 females, 387 males) aged between 2.20 and 15.99years were examined by two observers. A repeated measures ANOVA was performed to compare dental methods among gender and age groups. All of the five methods overestimated the chronological age on the average. Among these, Willems method was found to be the most accurate method, which showed 0.07 and 0.15years overestimation for males and females, respectively. It was followed by Demirjian's four teeth methods, revised and original methods. According to the results, Willems method can be recommended for dental age estimation of Turkish children in forensic applications.
本研究的目的是评估五种牙科方法的适用性，包括德米尔坚原始法、修订法、四牙法、交替四牙法以及威廉姆斯法，用于对一组土耳其儿童样本进行年龄估计。两名观察者检查了799名年龄在2.20至15.99岁之间儿童（412名女性，387名男性）的全景X线片。进行重复测量方差分析以比较不同性别和年龄组之间的牙科方法。这五种方法平均都高估了实际年龄。其中，威廉姆斯法被发现是最准确的方法，男性和女性的高估分别为0.07岁和0.15岁。其次是德米尔坚四牙法、修订法和原始法。根据结果，威廉姆斯法可推荐用于土耳其儿童法医应用中的牙龄估计。
