Abstract

BACKGROUND

The information of the association between residual alveolar bone height and mucosal thickening is sparse. This study aimed to explore the effect of maxillary molar periodontal status on sinus mucosal thickening using cone-beam computed tomography (CBCT).

METHODS

One hundred ninety-four CBCT images were evaluated for the following parameters: age, sex, alveolar bone loss, maximum mucosal thickness (maxMT), minimum residual alveolar bone height (minRABH), and vertical infrabony pockets. The presence of mucosal thickening (maxMT > 2 mm) of the maxillary sinus was recorded. The parameters that could influence the dimensions of the maxillary sinus membrane were assessed. The data were analyzed using logistic regression, and multivariate linear regression with the significant level at α = 0.05.

RESULTS

Mucosal thickening was present in 32% of the analyzed CBCT images and increased in frequency as the periodontal status of the corresponding molar progressed from mild (2.6%) to moderate (14.9%) to severe (75.5%). Mucosal thickness was significantly increased in cases of moderate (odds ratio = 5.73, P < 0.05) and severe (odds ratio = 82.06, P < 0.001) alveolar bone loss. Multivariate linear regression revealed that alveolar bone loss and minRABH had a statistically significant influence on maxMT (P < 0.05).

CONCLUSIONS

Alveolar bone loss and minRABH were significantly associated with mucosal thickening of the maxillary sinus.

摘要

背景

关于剩余牙槽骨高度与黏膜增厚之间关联的信息较为匮乏。本研究旨在使用锥形束 CT（CBCT）来探究上颌磨牙牙周状况对窦黏膜增厚的影响。

方法

评估了 194 个 CBCT 图像的以下参数：年龄、性别、牙槽骨丧失、最大黏膜厚度（maxMT）、最小剩余牙槽骨高度（minRABH）和垂直骨下袋。记录上颌窦黏膜增厚（maxMT>2mm）的情况。评估了可能影响上颌窦膜尺寸的参数。使用逻辑回归和具有 0.05 显著性水平的多元线性回归对数据进行分析。

结果

黏膜增厚存在于 32%的分析 CBCT 图像中，并且随着相应磨牙的牙周状况从轻度（2.6%）到中度（14.9%）再到重度（75.5%）进展，其发生率逐渐增加。中度（比值比=5.73，P<0.05）和重度（比值比=82.06，P<0.001）牙槽骨丧失的情况下，黏膜厚度显著增加。多元线性回归显示，牙槽骨丧失和 minRABH 对上颌窦 maxMT 有统计学显著影响（P<0.05）。
