摘要/Abstract

摘要： 目的　通过CBCT检查患根尖周炎的上颌后牙，探讨牙根尖周源性上颌窦黏膜炎的特点及根管治疗后黏膜及骨质的改变。方法: 对25例患上颌后牙根尖周炎患者上颌窦进行CBCT扫描重建，确诊为黏膜炎后，根管治疗3个月后CBCT扫描明确黏膜炎消退程度，6个月后扫描通过根尖周指数评估根尖骨质愈合情况。结果: 剔除2例上颌窦炎，14例上颌窦表现为黏膜炎（61％)，根管治疗3个月后，黏膜炎完全消退5例（35.7％）；部分消退6例（42.9％）；3例无明显改变（21.4％）。6个月后，3颗牙齿愈合（21.4％），4颗牙齿好转（28.6％），7颗牙齿未愈合（50％）。结论:上颌后牙根尖周炎易引发上颌窦黏膜炎，根管治疗是该疾病有效的治疗方法，CBCT影像能精确反映根管治疗前后上颌窦黏膜炎消退及骨质愈合情况，具有重要的临床参考价值。

Abstract: Objective　To investigate the characteristics of maxillary sinus mucositis adjacent to teeth with apical periodontitis (AP) and evaluate its resolution after endodontic treatment with cone beam computed tomography(CBCT). Methods 25 maxillary sinuses in patients who had AP associated with maxillary posterior teeth were scanned with CBCT. When mucositis was found, its resolution was evaluated with CBCT imaging 3 months after endodontic treatment, and periapical healing was assessed by the periapical index(PAI) after 6 months. Results Excluding 2 sinusitis, mucositis was found in 14 of 23 sinuses (61％). Three months after therapy, mucositis was fully resolved in 5 of 14 patients (35.7％), partially resolved in 6 of 14 patients(42.9％), unchanged in 3 patients(21.4％). Six months after treatment, a total of 3 of 14 teeth (21.4％) were healed, 4 of 14 teeth(28.6％) were healing, 7 of 14 teeth(50％) had persistent AP. Conclusions Endodontic treatment is an effective therapy for posterior teeth associated with AP which can easily trigger maxillary sinus mucositis. CBCT can accurately assess the resolution of maxillary sinus mucositis before and after endodontic treatment, which has important clinical reference value.
