Abstract：
(1) Background: In this study, the impact of odontogenic risk factors with nasal septum deviation on maxillary sinus mucosal thickening was assessed using Cone-beam computed tomography CBCT. (2) Methods: A total of 328 maxillary sinus regions from 164 patients (85 males and 79 females) were examined. Images were interpreted by dental specialists and Otolaryngologists. Coronal and sagittal sections were examined to assess the proximity of the root tips of posterior maxillary teeth (RPMT) to the maxillary sinus. The periodontal bone loss for all maxillary posterior teeth was also assessed. Consequently, maxillary sinus mucosal thickening (MT) was further classified into three gradings. Multilevel modeling regression analysis was used due to the hierarchical structuring of the data. Four models were developed, a null model with no factors, a model with tooth-level factors (RPMT, PBL, tooth condition, and root length), a model with patient-level factors (gender and nasal septum deviation), and a model with combined patient- and tooth-level factors. Regression estimates (AOR) and 95% confidence intervals (CIs) of individual and tooth factors were calculated. (3) Results: Multilevel regression analysis showed that RPMT was significantly associated with MT of maxillary sinus (p < 0.001), where patients who had RPMT > 0 had higher odds of MT of maxillary sinus. Tooth condition was also found to be significantly associated with MT of maxillary sinus, where teeth with failed RCT (p < 0.001) and teeth with restorations (p < 0.008) had higher odds of MT of maxillary sinus (AOR = 2.87, 95%CI 1.65, 4.42, AOR = 1.64, 95%CI 1.14, 2.36, respectively). (4) Conclusions: In order to plan preoperative treatment for maxillary posterior teeth, it is important to assess the anatomical relationship between the sinus floor and the root tips of the maxillary posterior teeth. Additionally, we establish a better understanding of the clinician before surgical intervention is conducted.
摘要：
(1)研究背景：在本研究中,使用锥形束计算机断层扫描CBCT评估鼻中隔偏曲的牙源性危险因素对上颌窦粘膜增厚的影响.(2)方法:对164例上颌窦区共328个,男85例,女79例。图像由牙科专家和耳鼻喉科医师解释。检查了冠状和矢状切面，以评估上颌后牙（RPMT）的根尖与上颌窦的接近程度。还评估了所有上颌后牙的牙周骨质流失。因此,上颌窦粘膜增厚（MT）进一步分为三个等级。由于数据的层次结构，因此使用了多级建模回归分析。开发了四个模型，一个没有因素的空模型，具有牙齿水平因子的模型(RPMT，PBL,牙齿状况,和根长)，具有患者水平因素（性别和鼻中隔偏曲）的模型，以及结合患者和牙齿水平因素的模型。计算了个体和牙齿因素的回归估计（AOR）和95％置信区间（CI）。(3)结果:多元回归分析显示RPMT与上颌窦MT显著相关(p<0.001),其中RPMT>0的患者上颌窦MT的几率更高。还发现牙齿状况与上颌窦MT显着相关，其中RCT失败的牙齿（p<0.001）和修复的牙齿（p<0.008）上颌窦MT的几率更高（分别为AOR=2.87，95CI1.65，4.42，AOR=1.64，95CI1.14，2.36）。(4)结论:上颌后牙的术前治疗方案,重要的是评估窦底和上颌后牙根尖之间的解剖关系。此外,在进行手术干预之前，我们对临床医生有了更好的了解。
