Assessment of relationship between maxillary sinus membrane thickening and the adjacent teeth health by cone-beam computed tomography.
Journal of Dental Sciences 2021 January
BACKGROUND/PURPOSE: Maxillary posterior teeth have close anatomical proximity to the maxillary sinus floor. The aim of this retrospective study was to evaluate the associations between maxillary sinus membrane thickening and the adjacent teeth health by cone-beam computed tomography (CBCT).
MATERIALS AND METHODS: CBCT images were collected from 235 Taiwanese patients. The sinus mucosal thickening >2 mm is considered a pathologic sinus membrane. Demographic data such as sex, age, the thickness of sinus membrane, and the adjacent teeth health were recorded, graded, and analyzed.
RESULTS: A total prevalence of maxillary sinus membrane thickening of 36.6% (86/235) was found in this study. The sinus membrane thickening was significantly associated with periodontal bone loss (p < 0.001) and periapical lesions (p < 0.001), respectively. A multivariate logistic regression model demonstrated that males had a significantly higher risk of sinus membrane thickening than females (OR: 2.08, 95% CI = 1.21-3.56). The patients in the age group ≥60 years showed a 4.35-fold increased risk of sinus membrane thickening compared with the patients in the age group ≤35 years (95% CI: 1.94-9.77). Severe periodontal bone loss was significantly associated with mucosal thickening with an OR of 4.78 as compared with normal to mild group (95% CI: 1.69-13.58). The patients having teeth with apical lesions had a 5.04 time OR for sinus membrane thickening than those having teeth without apical lesions (95% C.I.: 2.37-10.69).
CONCLUSION: The prevalence of maxillary sinus membrane thickening was more frequently occurred in male and older people. Periodontal bone loss and periapical lesions were significantly associated with maxillary sinus membrane thickening.
