本研究旨在通过使用锥形束计算机断层扫描（CBCT）图像评估上颌后牙根尖到窦底和颊侧皮质的距离，以评估根开窗或口窦交通的可能性。本研究包括219名患者的2182个上颌后牙牙根，由两位牙髓医生根据牙根位置对462名患者的CBCT图像进行回顾。根据性别和年龄评估每个根尖到上颌窦底和颊腭皮质的距离，并通过单因素方差分析和Mann-Whitney U检验比较平均值。上颌第一前磨牙根尖至上颌窦底的距离最大，上颌第二磨牙近颊根根尖至上颌窦底的距离最短。男性患者根尖至颊、腭皮质骨的距离大于女性患者（P
This study aimed to evaluate the possibility of root fenestration or oroantral communication by evaluating the distance from root apex to the sinus floor and buccal cortex in maxillary posterior teeth using cone-beam computed tomography (CBCT) images. The study included 2182 roots of the maxillary posterior teeth from 219 patients after reviewing CBCT images of 462 patients according to the location of roots by two endodontists. The distances from each root apex to the maxillary sinus floor and buccal and palatal cortices were evaluated according to sex and age, and the mean values were compared by one-way analysis of variance and Mann-Whitney U-test. The distance between root apex and maxillary sinus floor was the greatest in maxillary first premolars and shortest in the mesio-buccal roots of maxillary second molars. The distances from root apex to the buccal and palatal cortical bones were significantly greater in male patients than those in female patients (P
