To analysis the effect of nonoperative periodontal treatment on morphological changes of the schneiderian membrane of maxillary sinus in the chronic periodontitis patients by using oro-maxillaofacial cone-beam CT (CBCT) in order to provide the foundation in the diagnosis and treatment of maxillary sinusitis caused by chronic periodontitis. Totally 30 chronic periodontitis patients with schneiderian membrane thickening [(40.0±5.6) years old (ranged 26-55 years old), 18 males and 12 females] were randomly recruited in Department of Periodontics, School of Stomatology, China Medical University from June 2014 to December 2016. All patients were scanned by CBCT. The probing depth (PD), clinical attachment loss (CAL), plaque index (PLI) and bleeding index (BI) of the maxillary first and second premolars and molars were recorded. All patients received systematic nonoperative periodontal treatment. After six months, patients were reviewed, periodontal indexes and CBCT scanning were recorded. The thickness of the schneiderian membrane of maxillary sinus were analyzed by the software of CBCT. The changes of clinical parameters, parameter dimensional values of membrane thickness before and after treatment were statistically compared by test. In 30 chronic periodontitis patients, there was no statistically significant difference in the dimension and length of the maxillary sinus mucosa between the right and the left (0.05). The dimension of the mucosal thickening was positively correlated with PD and CAL values, and the correlation was statistically significant (0.05). Totally 58 maxillary sinus showed mucosal thickening. There were 20 mild thickening cases, and the dimension of mucosal thickening 6 months after treatment [(1.1±0.6) mm] was significantly lower than that before treatment [(2.5±0.7) mm] (0.05). There were 30 moderate thickening cases and the dimension of mucosal thickening 6 months after treatment [(2.3±0.6) mm] was significantly lower than that before treatment [(5.8±0.5) mm] (0.01). There were 8 severe thickening cases and the dimension of mucosal thickening 6 months after treatment [(4.2±0.4) mm] was also significantly lower than that before treatment [(11.2±1.8) mm] (0.01). The periodontal indexes of patients with mild, moderate and severe mucosal thickening in maxillary sinus showed statistically significant difference after treatment compared with before treatment (0.05). Nonoperative periodontal treatment has a positive therapeutic significance for improving the schneiderian membrane thickening of maxillary sinus.
为分析非手术牙周治疗对慢性牙周炎患者上颌窦黏膜形态变化的影响，采用口腔颌面锥形束CT（CBCT）进行研究，为慢性牙周炎所致上颌窦炎的诊治提供依据。2014年6月至2016年12月，在中国医科大学口腔医学院牙周科随机招募30例上颌窦黏膜增厚的慢性牙周炎患者[年龄（40.0±5.6）岁（范围26 - 55岁），男18例，女12例]。所有患者均行CBCT扫描，记录上颌第一、二前磨牙及磨牙的探诊深度（PD）、临床附着丧失（CAL）、菌斑指数（PLI）和出血指数（BI）。所有患者均接受系统的非手术牙周治疗。6个月后复查，记录牙周指标及CBCT扫描结果，采用CBCT软件分析上颌窦黏膜厚度。治疗前后临床参数、黏膜厚度参数测量值的变化采用t检验进行统计学比较。30例慢性牙周炎患者双侧上颌窦黏膜的大小和长度差异无统计学意义（P>0.05）。黏膜增厚大小与PD和CAL值呈正相关，且相关性具有统计学意义（P<0.05）。共58个上颌窦出现黏膜增厚，其中轻度增厚20例，治疗6个月后黏膜增厚大小[（1.1±0.6）mm]显著低于治疗前[（2.5±0.7）mm]（P<0.05）；中度增厚30例，治疗6个月后黏膜增厚大小[（2.3±0.6）mm]显著低于治疗前[（5.8±0.5）mm]（P<0.01）；重度增厚8例，治疗6个月后黏膜增厚大小[（4.2±0.4）mm]也显著低于治疗前[（11.2±1.8）mm]（P<0.
