Abstract

BACKGROUND

Due to the close proximity of maxillary molars to the maxillary sinuses, the bacteria at the root tip region of the sinus can quickly access the maxillary sinus. This can result in maxillary sinus mucosal inflammation and thickening of the Schneiderian membrane.

OBJECTIVES

The aim of the study was to determine the thickness of the maxillary sinus membrane and to correlate this thickening with the severity of periodontitis using cone beam computed tomography (CBCT) analysis.

MATERIAL AND METHODS

The CBCT data of 231 patients, with a mean age of 40.59 years, was assessed to evaluate the mucosal thickness (MT), the remaining height of the alveolar bone (RHAB), the type of periodontitis, the type of defect, and the extent of bone loss.

RESULTS

When RHAB was ≤4 mm, mucosal thickening was evident in the majority of the images (128 (89.5%); p = 0.000). The multivariate logistic regression analysis demonstrated that the probability of MT increase is proportionate to the severity of periodontal disease (odds ratio (OR): 9.179, confidence interval (CI): 2.831-29.761; p = 0.000). First molars were most frequently associated with mucosal thickening (OR: 1.050, CI: 0.311-3.541; p = 0.009). Additionally, mucosal thickening was more evident on the sinus floor in cases where RHAB was less than 4 mm.

CONCLUSIONS

The increase in MT is associated with the severity and distribution of periodontal disease, particularly with horizontal defects.

摘要

背景

由于上颌磨牙与上颌窦距离较近，窦根尖区的细菌可迅速进入上颌窦。这可导致上颌窦黏膜炎症及施奈德膜增厚。

目的

本研究旨在使用锥形束计算机断层扫描（CBCT）分析确定上颌窦膜的厚度，并将这种增厚与牙周炎的严重程度相关联。

材料与方法

评估了231例平均年龄为40.59岁患者的CBCT数据，以评估黏膜厚度（MT）、牙槽骨剩余高度（RHAB）、牙周炎类型、缺损类型和骨吸收程度。

结果

当RHAB≤4mm时，大多数图像中可见黏膜增厚（128例（89.5%）；p = 0.000）。多因素逻辑回归分析表明，MT增加的概率与牙周疾病的严重程度成正比（优势比（OR）：9.179，置信区间（CI）：2.831 - 29.761；p = 0.000）。第一磨牙最常与黏膜增厚相关（OR：1.050，CI：0.311 - 3.541；p = 0.009）。此外，在RHAB小于4mm的病例中，窦底的黏膜增厚更明显。
