Pathogenic factors of maxillary sinus mucosal thickening observed by cone-beam computed tomography (CBCT)
Abstract
Objective: To explore the pathogenic factors associated with maxillary sinus mucosal thickening with Cone -beam computed Tomography (CBCT). Methods: From 2016 through 2020, 93 patients with periapical periodontitis or periodontitis in the maxillary posterior dental region were selected. Results: The preoperative thickness of the periodontitis group was significantly higher than that of the periapical periodontitis group (P < 0.05). The difference achieves statistical significance for the comparison of the thickness change with various severity of inflammation (F = 54.824, P = 0.000), the change with time (F = 312.741, P = 0.000). and the change with the interaction severity of inflammation and time (F = 86.132, P = 0.000). Conclusions: Patients with maxillary sinus mucosa thickening caused by periodontitis and periapical periodontitis should be extracted their infectious teeth and get thoroughly debridement. Maxillary sinus augmentation can perform favorable efforts 3 -6 months after extracting teeth.
