Abstract
Objective: This study aimed to evaluate the accuracy of dental calcification stages in predicting the peak pubertal stage.
Methods: This retrospective study was conducted on panoramic and lateral cephalometric images of 406 female patients aged 9-14 years. The skeletal maturity and calcification stages of the mandibular canines, first premolars, second premolars, and second molars were determined using the Hassel-Farman and Demirjian (DI) methods, respectively. The prediction accuracy of the peak pubertal stage with the studied teeth was assessed using a receiver operating characteristic curve and the area under the curve (AUC). The DI stage of H was designated as the reference level, and Bayesian logistic regression analysis was used to assess the coinciding chance of each DI stage and peak pubertal stage.
Results: The AUC range of studied teeth was 0.84-0.92 in predicting peak pubertal stage (all p<0.001). In the canines and first premolars, the coinciding chance of peak pubertal stage and stage H was significantly higher than that in other stages [p<0.05, odds ratio (OR) ≤0.14]. In the second premolars and second molars, the chance of peak pubertal stage coinciding with stages H and G did not significantly differ (p>0.05); however, the chance of stage G coinciding with peak pubertal stage in the second molars was higher than in stage H (OR=4.59).
Conclusion: Stage H in all studied teeth and stage G in the second premolars and second molars predict peak pubertal stage with high accuracy. Considering that stage H is the end of tooth calcification stages and the accuracy of predicting stage G of second molar teeth is higher than the above stage, estimating the peak pubertal stage is recommended by the second case.
研究目的本研究旨在评估牙齿钙化阶段预测青春期高峰阶段的准确性:这项回顾性研究对 406 名 9-14 岁女性患者的全景和侧方头颅测量图像进行了分析。分别采用 Hassel-Farman 和 Demirjian(DI)方法确定了下颌犬齿、第一前磨牙、第二前磨牙和第二磨牙的骨骼成熟度和钙化阶段。使用接收器操作特征曲线和曲线下面积(AUC)评估了所研究牙齿青春期高峰阶段的预测准确性。将 H 的 DI 阶段定为参考水平,并使用贝叶斯逻辑回归分析评估各 DI 阶段与青春期高峰阶段的吻合几率:研究牙齿在预测青春期高峰阶段方面的AUC范围为0.84-0.92(均为P0.05);然而,第二磨牙中G阶段与青春期高峰阶段重合的几率高于H阶段(OR=4.59):结论:所有研究牙齿的 H 期以及第二前磨牙和第二磨牙的 G 期均能准确预测青春期高峰。考虑到 H 阶段是牙齿钙化阶段的末期,且第二磨牙 G 阶段的预测准确率高于上述阶段,因此第二种情况建议对青春期高峰阶段进行估计。
