Study Title:

Cone-beam computed tomographic evidence of the association between periodontal bone loss and mucosal thickening of the maxillary sinus.

Study Abstract

BACKGROUND:

The aim of the present study is to determine the relationship between dental findings and mucosal abnormalities of the maxillary sinus among dental patients, using cone-beam computed tomography (CBCT).
METHODS:

Two hundred fifty CBCT scans of dental patients were studied. Dental findings of the upper posterior teeth, including periodontal bone loss, periapical lesions, and root canal fillings, were assessed. The presence of mucosal thickening and mucosal cysts of the maxillary sinus was recorded. Logistic regression analysis was used to determine the influence of periodontal bone loss, periapical lesions, and root canal fillings on these sinus mucosal abnormalities.
RESULTS:

Mucosal thickening was present in 42% of patients and in 29.2% of sinuses studied. Mucosal cysts were observed in 16.4% of patients and in 10% of sinuses studied. Both abnormalities were present more frequently among males than females. Severe periodontal bone loss was significantly associated with mucosal thickening (odds ratio: 3.02, P <0.001), whereas periapical lesions and root canal fillings were not. There was no association between dental findings and mucosal cysts.
CONCLUSIONS:

Severe periodontal bone loss was significantly associated with mucosal thickening of the maxillary sinus. Sinuses with severe periodontal bone loss were three times more likely to have mucosal thickening. Mucosal cysts were not associated with any dental findings.
