AIM
The purpose of the present study was to evaluate the relationship between the maxillary sinus floor and the upper posterior root tips in the Colombian population using cone-beam computed tomography.
METHODS
A total of 1656 roots were analyzed (1104 molars and 552 premolars), classified as types I (outside the maxillary sinus) and II (inside the maxillary sinus).
RESULTS
The results showed that the palatal root of the maxillary first molar was most frequently found inside the antrum.
CONCLUSIONS
Understanding the relationship between the maxillary sinus floor and the upper posterior root tips is important to the clinician when performing conventional or surgical endodontic treatment and conventional surgery procedures in order to minimize or avoid the risk of damaging the maxillary sinus.
目的
本研究旨在使用锥形束计算机断层扫描评估哥伦比亚人群中上颌窦底与上颌后牙根尖之间的关系。
方法
共分析了1656颗牙根（1104颗磨牙和552颗前磨牙），分为I型（在上颌窦外）和II型（在上颌窦内）。
结果
结果显示，上颌第一磨牙的腭根最常位于窦腔内。
结论
了解上颌窦底与上颌后牙根尖之间的关系，对于临床医生在进行常规或外科牙髓治疗及常规外科手术时，为尽量减少或避免损伤上颌窦的风险具有重要意义。
