ObjectivesThe purpose of this study was to evaluate the prevalence of sinus mucosal thickness (MT) and mucosal appearance (MA) in a patient population as detected with cone beam computed tomography (CBCT) and to determine the associations of various disease and demographic factors on MT and MA.Study DesignThe retrospective study consisted of CBCT images of 1000 maxillary arches in 500 patients. The arches were divided into three groups (atrophic, partially atrophic, and non-atrophic) according to the type of the maxillary dental crest. The CBCT scans were assessed to detect the prevalence of maxillary sinus MT and MA. Chi-square analysis was used to determine the significance of association of periodontal bone loss (PBL), periapical status (PA), alveolar crest type, age, and gender on sinus MT and MA.ResultsMT was significantly associated with PBL (P=0.004), PA status (P=0.001), and gender (P<0.01). MA was significantly associated with PBL (P=0.038), PA status (P=0.009), and gender (P<0.020) There were no significant associations of age or crest type with either MT or MA.ConclusionsPeriodontal bone loss, periapical lesions, and gender may have an association with mucosal thickening of the maxillary sinus.
