The aims of this study were to assess the accuracy of Cameriere's and Demirjian's methods in Finnish children, and compare the findings with those of the Turkish children according to dental age.
Dental panoramic tomography (DPT) of children (482 Finnish, 423 Turkish) aged between 5 and 15 years were evaluated. Comparison of mean difference between estimated and chronological age was evaluated. The difference between two means was analysed using paired t-test at 95% confidence interval (CI). Pearson correlation coefficients were used to estimate the correlation between chronological and estimated ages. Results: Demirjian's method resulted in overestimation in all age groups except for 8-year-old girls. Dental age, however, was found to be underestimated with Cameriere's method in all age groups but 6-year-old girls and boys. In Northern Finnish children, Demirjian's method was more suitable for boys while Cameriere's method led to better estimation in girls. When comparing Finnish and Turkish children, differences between dental ages and chronological ages differed significantly in 10-year-old boys and 8-year-old girls with both methods. Conclusion: Dental age of Turkish children seems higher than that of Finnish children. There is a significant difference between chronological and dental ages in both populations assessed by both methods.
本研究旨在评估 Cameriere 法和 Demirjian 法在芬兰儿童中的准确性，并根据牙龄比较与土耳其儿童的发现。
评估了年龄在 5 至 15 岁之间的儿童（482 名芬兰儿童和 423 名土耳其儿童）的牙科全景断层扫描（DPT）。比较了估计年龄和实际年龄之间的平均差异。在 95%置信区间（CI）下使用配对 t 检验分析两个平均值之间的差异。使用皮尔逊相关系数估计实际年龄和估计年龄之间的相关性。结果：Demirjian 法在所有年龄组中均存在高估，除了 8 岁女孩组。然而，Cameriere 法在所有年龄组中均低估了牙龄，但在 6 岁女孩和男孩组中除外。在芬兰北部儿童中，Demirjian 法更适合男孩，而 Cameriere 法则更适合女孩。在比较芬兰和土耳其儿童时，两种方法均显示 10 岁男孩和 8 岁女孩的牙龄和实际年龄之间的差异具有统计学意义。结论：与芬兰儿童相比，土耳其儿童的牙龄似乎更高。两种方法评估的两个人群的实际年龄和牙龄之间存在显著差异。
