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.
背景
牙龄估算是确定年龄的最可靠方法之一，常用于法医学、犯罪学和人类学目的。本研究旨在评估和比较 Bedek 模型和 Cameriere-European 公式（CF）在确定土耳其人群样本中牙龄的精确性。
方法
使用 Bedek 模型和 CF 对 1018 名年龄在 5-14 岁的受试者（497 名男孩和 521 名女孩）的回顾性全景片进行评估。使用配对样本 t 检验和 Wilcoxon 符号秩检验分析每个性别和年龄组的计算牙龄（DA）与实际年龄（CA）之间的差异。通过计算牙龄与实际年龄的接近程度，基于平均绝对误差（MAE）确定估计牙龄的方法的准确性。
结果
CF 方法在整个样本中高估了 CA，高估了 0.1 岁。相反，Bedek 模型倾向于高估 CA，其中三、四、七齿模型的差异最大。在整个样本中，CF 方法计算的 DA-CA 中，男孩和女孩之间存在统计学差异。在 Bedek 模型中，三齿和四齿模型在整个样本中具有最低的 MAE，而单齿模型具有最高的 MAE。
结论
与 Bedek 模型相比，CF 方法在预测生活在土耳其东部的儿童年龄方面显示出更高的准确性。
