Dental age estimation in children plays an important role in forensic dentistry. The most commonly used method for age estimation was developed by Demirjian in 1973 on a French-Canadian sample. It generally overestimates dental age in many populations. International maturity standards were formed to obtain a predicted age with more confidence when ethnic origin was not available.
The aim of this study was to evaluate the applicability of Chaillet's international scores in the dental age assessment on Bosnian Herzegovinian (BH) children.
Orthopantomograms of 1772 children, 980 girls and 792 boys aged 6.04-14.90 years, were assessed using Chaillet's international maturity tables and curves. The dental ages for both genders were compared to the chronological ages through a paired t-test.
Mean overestimation using Chaillet's international maturity standards were 0.09 ± 0.83 for girls and 0.28 ± 0.90 for boys. The absolute accuracy of residuals between the dental and chronological age were 0.65 ± 0.52 years for girls (Median: 0.52 years) and 0.73 ± 0.60 years for boys (Median: 0.57 years).
The Polynomial compound formula was recommended to predict dental age with more accuracy for results of international maturity standards on BH children.
儿童牙齿年龄估计在法医牙科学中起着重要作用。最常用的年龄估计方法由德米尔坚于1973年在法裔加拿大样本上开发。在许多人群中，该方法通常会高估牙齿年龄。国际成熟标准的形成是为了在无法得知种族来源时更有信心地获得预测年龄。
本研究的目的是评估沙耶国际评分在波斯尼亚和黑塞哥维那（BH）儿童牙齿年龄评估中的适用性。
使用沙耶国际成熟度表和曲线对1772名年龄在6.04 - 14.90岁之间的儿童（980名女孩和792名男孩）的曲面断层片进行评估。通过配对t检验将两性的牙齿年龄与实际年龄进行比较。
使用沙耶国际成熟标准，女孩的平均高估为0.09 ± 0.83，男孩为0.28 ± 0.90。牙齿年龄与实际年龄之间残差的绝对准确度，女孩为0.65 ± 0.52岁（中位数：0.52岁），男孩为0.73 ± 0.60岁（中位数：0.57岁）。
对于BH儿童国际成熟标准的结果，建议使用多项式复合公式更准确地预测牙齿年龄。
