Endodontic infections of posterior maxillary teeth sometimes spread to the maxillary sinus, generating severe complications. The aim of this study is to present the various problems encountered during endodontic treatment of these teeth.
The files of 125 cases of odontogenic chronic maxillary sinusitis were reviewed retrospectively.
Chronic apical periodontitis was the cause in 99 cases and traumatising endodontic treatment in 26 cases. Foreign intra-sinusal bodies were occasionally seen as a consequence of different endodontic treatments of posterior maxillary teeth.
A knowledge of dento-antral relationships is particularly important in the prevention of sinusal accidents and complications during various therapeutic manoeuvres, which should be performed according to and depending on the regional morphology.
上颌后牙的牙髓感染有时会蔓延至上颌窦，引发严重并发症。本研究旨在阐述这些牙齿牙髓治疗过程中遇到的各种问题。
回顾性分析125例牙源性慢性上颌窦炎病例的档案。
99例病因是慢性根尖周炎，26例是牙髓治疗创伤。上颌后牙不同牙髓治疗偶尔会导致鼻窦内出现异物。
了解牙-窦关系对于预防各种治疗操作过程中的鼻窦意外和并发症尤为重要，这些操作应根据局部形态并依赖于局部形态来进行。
