Dental age estimation in children is an important issue both legally and medically. Currently, however, there is a lack of contemporary dental age estimation standards for a Turkish population. This study assessed the accuracy of Cameriere's method by examining the panoramic radiographs of 573 healthy Turkish children between the ages of 8 and 15 years. Radiographs of the left permanent developing mandibular teeth, except wisdom teeth, were evaluated. All subjects were divided into 7 groups according to their chronological age. The Intra-class Correlation Coefficient was used to determine the intra- and inter-observer agreement error. A comparison of the distributions of estimation errors among age groups was performed using the Nemenyi test. There were no significant differences between inter-observer (p=0.352), and intra-observer readings after 2 weeks (p=0.275 and p=0.273, respectively). The dental age was underestimated when using Cameriere's method with a mean difference of -0.35 years (-0.24 years for girls and -0.47 years for boys). The median values of the differences between dental and chronological age were -0.44 years in boys (range: -3.70, 4.06) and -0.21 years in girls (range: -2.74, 3.29). In addition, the differences between dental and chronological ages in the different age groups decreased with increasing chronological age. Results from the Nemenyi test implied that Cameriere's method is more accurate for girls than for boys in this cohort of a Turkish population.
儿童牙齿年龄估计在法律和医学上都是一个重要问题。然而，目前缺乏针对土耳其人群的当代牙齿年龄估计标准。本研究通过检查573名8至15岁健康土耳其儿童的全景X线片，评估了卡梅里埃方法的准确性。对除智齿外的左侧恒牙发育中的下颌牙齿的X线片进行了评估。所有受试者根据其实际年龄分为7组。组内相关系数用于确定观察者内和观察者间的一致性误差。使用内曼-皮尔逊检验对各年龄组估计误差的分布进行比较。观察者间（p=0.352）以及2周后观察者内读数之间均无显著差异（分别为p=0.275和p=0.273）。使用卡梅里埃方法时牙齿年龄被低估，平均差异为-0.35岁（女孩为-0.24岁，男孩为-0.47岁）。男孩牙齿年龄与实际年龄差异的中位数为-0.44岁（范围：-3.70，4.06），女孩为-0.21岁（范围：-2.74，3.29）。此外，不同年龄组牙齿年龄与实际年龄的差异随实际年龄的增加而减小。内曼-皮尔逊检验结果表明，在这一土耳其人群队列中，卡梅里埃方法对女孩的准确性高于男孩。
