Age estimation is an inescapable part of every identification process. During growth and development, it is possible to estimate age based on the developmental stages of teeth. The aim of this study was to evaluate three frequently used methods for dental age estimation on a broad sample of Croatian children. The sample comprised 1996 digital, standardized orthopantomograms of children (1121 boys and 875 girls) aged 5 to 16, collected in four major Croatian cities. Age was estimated according to the Demirjian, Willems and Haavikko methods and the accuracy of the estimation was evaluated. The Kappa for intra-examiner agreement was 0.83 for the Haavikko stages and 0.92 for the Demirjian stages. Using the Demirjian method, the average overestimation of age was 0.80 years for boys and 0.84 years for girls. The Willems method overestimated the mean age by 0.41 years in boys and 0.22 years in girls. The Haavikko method underestimated the mean age by 0.60 years in boys and 0.80 years in girls. The Willems method proved to be the most accurate and can be used for dental age estimation among Croatian children. The Demirjian and Haavikko methods showed greater deviation between dental and chronological age and require adaptation when used in the Croatian population.
年龄估算是每个鉴定过程中不可避免的一部分。在生长发育过程中，可以根据牙齿的发育阶段来估计年龄。本研究旨在评估三种常用于克罗地亚儿童的牙齿年龄估计方法。该样本包括来自四个主要克罗地亚城市的 1996 名 5 至 16 岁儿童的数字标准化全景片（1121 名男孩和 875 名女孩）。根据 Demirjian、Willems 和 Haavikko 方法估计年龄，并评估估计的准确性。Haavikko 阶段的内部检查者一致性 Kappa 值为 0.83，Demirjian 阶段的 Kappa 值为 0.92。使用 Demirjian 方法，男孩的平均年龄高估为 0.80 岁，女孩的平均年龄高估为 0.84 岁。Willems 方法使男孩的平均年龄高估了 0.41 岁，女孩的平均年龄高估了 0.22 岁。Haavikko 方法使男孩的平均年龄低估了 0.60 岁，女孩的平均年龄低估了 0.80 岁。Willems 方法被证明是最准确的，可以用于克罗地亚儿童的牙齿年龄估计。Demirjian 和 Haavikko 方法显示出牙齿年龄和实际年龄之间的偏差更大，在克罗地亚人群中使用时需要进行调整。
