Abstract

Background: Dental age estimation is one of the most reliable methods for determining age, commonly used for forensic, criminal, and anthropological purposes. The purpose of this study was to assess and compare the precision of the Bedek models and the Cameriere-European Formula (CF) in determinating dental age in a sample of Turkish individuals.

Methods: Retrospective panoramic radiographs of 1018 subjects (497 boys and 521 girls) aged 5-14 years were evaluated using the Bedek models and the CF. The differences between calculated dental age (DA) and chronological age (CA) for each sex and age group were analyzed using the paired sample t-test and the Wilcoxon signed-rank test. The accuracy of the methods used to estimate dental age was determined by calculating the mean absolute error (MAE) based on the proximity of the dental age to the chronological age.

Results: The CF method overestimated CA by 0.1 year in the entire sample. Conversely, the Bedek models tended to overestimate CA, with the three-, four-, and seven-tooth models exhibiting the most significant difference. There was a statistically significant difference between boys and girls in the DA-CA calculation using the CF method in the entire sample. Among the Bedek models, the three- and four-tooth models had the lowest MAE in the entire sample, while the single-tooth model had the highest MAE.

Conclusion: The CF method showed higher accuracy in predicting the age of children living in eastern Turkey compared to the Bedek Models.

对土耳其儿童牙科年龄预测中使用的贝德克模型和卡梅里埃-欧洲公式有效性的调查。

背景：牙齿年龄估计是确定年龄最可靠的方法之一，常用于法医、刑事和人类学目的。本研究的目的是评估和比较贝德克模型和卡梅里埃-欧洲公式（CF）在确定土耳其人样本牙齿年龄方面的精确度：方法：使用贝德克模型和卡美瑞尔-欧洲公式对 1018 名 5-14 岁受试者（497 名男孩和 521 名女孩）的回顾性全景 X 光片进行评估。使用配对样本 t 检验和 Wilcoxon 符号秩检验分析了每个性别和年龄组的计算牙龄（DA）和计时年龄（CA）之间的差异。通过计算平均绝对误差（MAE）来确定估算牙龄所用方法的准确性，而平均绝对误差是根据牙龄与实际年龄的接近程度来计算的：在整个样本中，CF 方法高估了 CA 0.1 岁。相反，贝德克模型倾向于高估CA，其中三齿、四齿和七齿模型的差异最为显著。在整个样本中，使用 CF 法计算 DA-CA 时，男孩和女孩之间的差异在统计学上有显著性。在贝德克模型中，三齿和四齿模型的 MAE 在整个样本中最低，而单齿模型的 MAE 最高：结论：与贝德克模型相比，CF 方法在预测土耳其东部儿童年龄方面表现出更高的准确性。
