对720例健康儿童（A组）、320例儿童和280例亚成人（B组）的正断层片进行了评估。基于训练数据集1建立了华南地区特有的公式，并利用测试数据集1对Cameriere的欧洲公式和华南地区特有的公式进行了精度比较。基于训练数据集2建立了PT回归模型、TM回归模型和组合回归模型（PT + TM），并在测试数据集2上验证了这三个模型的性能。华南地区公式更适合华南地区儿童的牙龄估计，PT和TM联合模型可提高儿童牙龄估计的准确性。本研究的目的是评估Cameriere的欧洲公式在中国南方儿童年龄估计的适用性，并调整公式，以建立一个更适合这些儿童的公式。此外，Cameriere的方法结合恒牙（PT）和第三磨牙（TM）的发育信息的牙龄估计的性能进行了分析。对720例健康儿童（A组）、320例儿童和280例亚成人（B组）的正断层片进行了评估。A组样本分为训练数据集1和测试数据集1，B组样本也分为训练数据集2和测试数据集2。基于训练数据集1建立了华南地区特有的公式，并利用测试数据集1对Cameriere的欧洲公式和华南地区特有的公式进行了精度比较。此外，基于训练数据集2建立了PT回归模型、TM回归模型和组合回归模型（PT + TM），并在测试数据集2上验证了这三个模型的性能。Cameriere的欧洲公式低估了实际年龄，男性的平均差异（ME）为-0.47 ± 1.11岁，女性为-0.69 ± 1.19岁。然而，华南地区的公式低估了实际年龄，男性的平均差异（ME）为-0.02 ± 0.71岁，女性为-0.14 ± 0.73岁。与PT模型和TM模型相比，PT和TM组合模型获得的均方根误差（RMSE）最小，男性为1.29年，女性为0.93年。结论：华南地区儿童牙龄估算公式更适合华南地区儿童牙龄的估算，PT和TM联合模型可提高儿童牙龄估算的准确性。
Orthopantomographs of 720 healthy children in Group A, and orthopantomographs of 320 children and 280 subadults in Group B were assessed. A South China-specific formula was established based on the training dataset 1, and the comparison of accuracy between the Cameriere’s European formula and the South China-specific formula was conducted with the test dataset 1. A PT regression model, a TM regression model, and a combined regression model (PT + TM) were established based on the training dataset 2, and the performance of these three models were validated on the test dataset 2. The South China-specific formula was more suitable for assessing the dental age of children in South China, and the PT and TM combined model can improve the accuracy of dental age estimation in children. The aim of this study was to evaluate the applicability of Cameriere’s European formula for age estimation in children in South China and to adapt the formula to establish a more suitable formula for these children. Moreover, the performance of dental age estimation based on Cameriere’s method combining the developmental information of permanent teeth (PT) and third molar (TM) was also analysed. Orthopantomographs of 720 healthy children in Group A, and orthopantomographs of 320 children and 280 subadults in Group B were assessed. The samples of Group A were divided into training dataset 1 and test dataset 1, and the samples of Group B were also divided into training dataset 2 and test dataset 2. A South China-specific formula was established based on the training dataset 1, and the comparison of accuracy between the Cameriere’s European formula and the South China-specific formula was conducted with the test dataset 1. Additionally, a PT regression model, a TM regression model, and a combined regression model (PT + TM) were established based on the training dataset 2, and the performance of these three models were validated on the test dataset 2. The Cameriere’s European formula underestimated chronological age with a mean difference (ME) of −0.47 ± 1.11 years in males and −0.69 ± 1.19 years in females. However, the South China-specific formula underestimated chronological age, with a mean difference (ME) of −0.02 ± 0.71 years in males and −0.14 ± 0.73 years in females. Compared with PT model and TM model, the PT and TM combined model obtained the smallest root mean square error (RMSE) of 1.29 years in males and 0.93 years in females. In conclusion, the South China-specific formula was more suitable for assessing the dental age of children in South China, and the PT and TM combined model can improve the accuracy of dental age estimation in children.
