Co-relation between periodontitis and maxillary sinusitis: A cross sectional CBCT based study

Periodontitis is a potential but often underdiagnosed cause of maxillary sinusitis, complicating accurate diagnosis due to overlapping clinical features. Therefore, it is of interest to evaluate the correlation between alveolar bone loss and maxillary sinus mucosal thickening in 50 patients with periodontitis. Measurements were performed in coronal and sagittal sections to assess the extent of periodontal destruction and sinus involvement. A significant association was observed, with greater mucosal thickening in patients exhibiting moderate to severe alveolar bone loss compared to mild cases. Thus, we show the importance of through periodontal evaluation in patients presenting with maxillary sinusitis to ensure accurate diagnosis and management.
