在本研究中，我们旨在根据上颌埋伏牙的唇腭位置分析其在全景x线片上的根尖位置，并提出一种新的上颌埋伏牙全景x线片预测指标。方法：选取104例单侧上颌埋伏牙患者的成对全景片和锥束ct图像。比较全景片上阻生犬根尖的扇形位置与锥束ct上上颌阻生犬根尖的唇腭位置。用卡方检验检验全景和锥束计算机断层扫描结果之间的统计相关性。结果：阻生犬根尖扇形位置与犬的唇腭位置有显著的统计学意义(P
Introduction: In this study, we aimed to analyze the root apex positions of impacted maxillary canines on panoramic radiographs according to their labiopalatal positions and to propose a new panoramic radiographic predictor of impacted maxillary canines. Methods: Paired panoramic films and cone-beam computed tomography images of 104 patients with unilateral impactedmaxillary canines were selected. The sector locations of the impacted canine root apices on the panoramic radiographs were compared with the labiopalatal positions of impacted maxillary canines on cone-beam computed tomography. Statistical correlations between panoramic and cone-beam computed tomography findings were examined with the chi-square test. Results: A statistically significant association was observed between the sector locations of impacted canine root apices and the labiopalatal positions of the canines (P
