Abstract

Aim: Evaluate the volume of the maxillary sinus in subjects with unilaterally impacted maxillary canine using cone beam computed tomography (CBCT) and compare the sinus volume in subjects with unilateral buccal or palatal maxillary canine impaction. Materials and Methods: CBCT scans of 40 subjects with unilaterally impacted maxillary canines (20 with unilateral buccal impaction and 20 with unilateral palatal impaction) were used to compare the maxillary sinus volumes between the impacted and the normal sides. Also, the maxillary sinus volume in patients with unilateral buccally maxillary impacted canine was compared with those with unilateral palatally maxillary impacted canine. The materialize mimics 21.0 software program was used to calculate the volume of the maxillary sinus. Results: The volume of the maxillary sinus was statistically significantly smaller in the impaction side (11377.17 ± 1386.87 mm3) compared to the contralateral side (12770.71 ± 1621.24 mm3). However, there is no significant effect of the site of impaction either buccally or palatally on the volume of the maxillary sinus. Conclusion: A volumetric decrease in the maxillary sinus volume can be expected when the maxillary canines are impacted.
