  • Title: Significance of maxillary sinus mucosal thickening in patients with periodontal disease.
    Author: Ren S, Zhao H, Liu J, Wang Q, Pan Y.
    Journal: Int Dent J; 2015 Dec; 65(6):303-10. PubMed ID: 26453062.
    Abstract:
    AIM: To characterise and measure the Schneiderian membranes of individuals with periodontal diseases in China and to analyse the factors impacting maxillary sinus mucosal thickness using cone-beam computed tomography (CBCT). MATERIAL AND METHOD: A cohort of 221 patients with periodontal disease was subjected to cross-sectional CBCT examination. Various parameters, including age, sex, alveolar bone loss, furcation lesions and vertical infrabony pockets, were analysed as correlates of mucosal thickening (MT). Sinus mucosal thickness ≥ 2 mm qualified as MT. RESULTS: MT was detected in 103 (48.9%) patients, increasing in frequency as the degree of alveolar bone loss advanced (mild, 14.5%; moderate, 29.5%; severe, 87.9%). The association between MT and vertical infrabony pockets was statistically significant (P < 0.001). The likelihood of MT increased with moderate [odds ratio (OR) = 1.02] and severe (OR = 4.62) periodontal bone loss (P < 0.001), as well as with furcation lesions (OR = 2.76) and vertical infrabony pockets (OR = 13.58). CONCLUSIONS: Relative to the case in patients with periodontitis and normal mucosa, the probability of MT increased dramatically as alveolar bone loss worsened. Periodontal pathologies (i.e. furcation lesions and vertical infrabony pockets) were also more likely to coincide with MT.
