Tooth development evaluation is majorly the current approach to identify age and maturity. Dental age (DA) is therefore considerably emphasized in forensic and pediatric dentistry. The aim of this study was to assess the applicability of Willems and Cameriere methods for Turkish children. Panoramic images of 636 Turkish healthy children (319 male; 317 female) aged between 6 and 15 years were assessed. DA of the subjects was determined by using Willems and Cameriere methods. The seven right and left permanent lower teeth were valued using these two methods. The mean chronological age (CA) of the subjects was 11.53±2.25 (min:6, max:14.99) years (boys: 11.29±2.34 years, girls: 11.77±2.15 years). Willems method overestimated the CA (p≤0.001), in contrast, Cameriere method underestimated the CA (p≤0.001) for both sexes. In different age groups the mean difference between the CA and DA calculated by Cameriere method (CADA) ranged from 0.86 to -0.41 years for boys and from 1.00 to -0.21 years for girls, while the mean difference between the CA and DA calculated by Willems method ranged from -0.26 to -0.71 years for boys and from 0.19 to -0.76 years for girls. Cameriere method provided a better percentage of accuracy (84.6% and 77.3% for males and females, respectively) in the absolute difference values within 1 year compared to Willems method. Cameriere method performed slightly better but, both methods may be used for DA estimation in the Turkish population.
牙齿发育评估主要用于鉴定年龄和成熟度。因此，牙龄（DA）在法医和儿科牙科中得到了相当大的重视。本研究旨在评估 Willems 和 Cameriere 方法在土耳其儿童中的适用性。评估了 636 名土耳其健康儿童（319 名男性；317 名女性）的全景图像，年龄在 6 至 15 岁之间。使用 Willems 和 Cameriere 方法确定受试者的 DA。使用这两种方法对 7 颗左右的恒下恒牙进行了评估。受试者的平均年龄（CA）为 11.53±2.25（min：6，max：14.99）岁（男孩：11.29±2.34 岁，女孩：11.77±2.15 岁）。Willems 方法高估了 CA（p≤0.001），相反，Cameriere 方法低估了 CA（p≤0.001），无论是男孩还是女孩。在不同的年龄组中，Cameriere 方法计算的 CA 和 DA 之间的平均差值（CADA）在男孩中从 0.86 到-0.41 岁，在女孩中从 1.00 到-0.21 岁，而 Willems 方法计算的 CA 和 DA 之间的平均差值在男孩中从-0.26 到-0.71 岁，在女孩中从 0.19 到-0.76 岁。与 Willems 方法相比，Cameriere 方法在 1 年内绝对差值的准确性百分比（分别为 84.6%和 77.3%，男性和女性）更高。Cameriere 方法的表现稍好，但两种方法均可用于土耳其人群的 DA 估计。
