摘　　要：目的应用锥束计算机断层扫描(CBCT)对上颌后牙根尖及牙周状况与上颌窦病变的影像学表现进行测量与分析,探究其相互之间的影响。方法按标准选取就诊于辽宁省人民医院口腔科门诊所摄的132例224个上颌窦的CBCT影像资料,测量上颌窦黏膜厚度、上颌后牙CBCT根尖周指数(CBCT-PAI)、牙周骨丢失程度,根尖或根尖部病变与上颌窦的位置关系,并记录根尖周病变的牙位情况。结果上颌后牙根尖周病变CBCT-PAI分值与上颌窦黏膜厚度之间存在线性相关(P<0.001),上颌后牙牙周骨丢失程度与上颌窦黏膜厚度之间存在线性相关(P<0.001),Ⅰ型位置关系的牙齿数目与上颌窦黏膜增厚无线性趋势相关(P>0.05),上颌后牙根尖周病变与上颌窦病变相关中常见的牙齿为上颌第一磨牙和第二磨牙。结论上颌后牙根尖周病变和牙周骨丢失与上颌窦病变密切相关。Objective Cone beam computed tomography(CBCT)was used to measure and analyze the apical and periodontal status of maxillary posterior teeth and the imaging manifestations of maxillary sinus lesions,and to explorethe interaction betweenthem.Methods According to the criteria,132 patients with 224 maxillary sinuses were selected from the outpatient department of Stomatology of Liaoning People's Hospital,the maxillary sinus mucosathickening,CBCT-PAI of maxillary posterior teeth and periodontal bone loss were measured,the positional relationship between the apex or apical lesion and the maxillary sinus,and the location of periapical lesions was recorded.Results There was a linear correlation between CBCT-PAI score and maxillary sinus mucosal thickness in periapical lesions of maxillary posterior teeth(P<0.001).There was a linear correlation between the degree of periodontal bone loss of maxillary posterior teeth and the thickness of maxillary sinus mucosa(P<0.001).The number of teeth in the type I positional relationship was related to the wireless trend of maxillary sinus mucosal thickening(P>0.05).The most common teeth associated with periapical lesions of maxillary posterior teeth and maxillary sinus lesions are maxillary first molar and second molar.Conclusion Periapical lesions and periodontal bone loss of maxillary posterior teeth are closely related to maxillary sinus lesions.
