摘要： 目的:结合锥形束CT(CBCT),通过分析曲面断层片、头颅侧位片,得出上颌埋伏尖牙引起切牙牙根吸收的预测方程。方法:收集符合标准的病例,根据邻近切牙是否发生吸收分成吸收组和未吸收组.所有患者拍摄曲面断层片、头颅侧位片和CBCT并进行测量。结果:确定与切牙牙根是否发生吸收相关的指标,建立切牙牙根吸收预测方程。结论:通过对曲面断层片和头颅侧位片的测量,可初步预测上颌埋伏尖牙是否已造成邻近切牙牙根吸收。中切牙预测方程准确率高,具有一定临床意义;侧切牙预测准确率较低,尚无法应用于临床。

Abstract: Objective: To establish an equation to predict the incisors root resorption caused by impacted canines using two-dimensional radiography and cone-beam computed tomography (CBCT). Methods: Objects complying with relevant standard were collected. Subjects were divided into incisor root resorption group and non-resorption group according to the resorption condition of adjacent incisors. Each patient took panoramic radiograph, lateral cephalometric radiograph, and CBCT. Results: The indicators related to incisors root resorption was identified, and then the prediction equation was established according to the results. Conclusion: The incisors root resorption caused by impacted maxillary canines can be explored by the measurements of panoramic radiograph and lateral cephalometric radiograph. The high accuracy rate of central incisors prediction equation indicates that the equation can guide clinical practice. However, the low accuracy rate of lateral incisors prediction equation implies negative information.
