Three-dimensional evaluation of maxillary sinus volume, skeletal and dentoalveolar maxillary anterior region, in unilateral palatally impacted maxillary canine (Cross-sectional study).

Abstract

Three-dimensional evaluation of maxillary sinus volume using VR mesh and correlate it with the volume of maxillary canine, lateral incisor, and dentoalveolar and skeletal dimensions in both impacted and non-impacted sites. In a retrospective cross-sectional study, cone beam computed tomography scans of 100 patients with unilateral palatally impacted maxillary canine were analyzed. Canine, lateral incisor, and maxillary sinus volumes on the impaction and non-impaction sides were measured using DICOM files, with three-dimensional softwares (MIMICS) and VR mesh to accomplish this assessment. There were no significant differences in canine and lateral incisors volumes between male and female patients in the impacted side at (p > 0.05) while the maxillary sinuses volume revealed a statistical difference (P = 0.022) between male (12642 ± 810) and female (12481 ± 650) patients in the impacted side. A strong positive correlation was found between canine and lateral incisor volume for male patients in the non-impacted (r = 0.420**, P = 0.008) and impacted sides (r = 0.334*, P = 0.038). There were no significant differences in the canine volume, the height of the anterior alveolar ridge (AARHMLI), and anterior dentoalveolar (ADAHMLI) of maxillary lateral incisors in the impacted/non-impacted side, but it showed a statistically significant difference for the lateral incisors volume in the impacted and non-impacted sides for male and female patients. The maxillary sinus volumes revealed a statistical difference between males and females in impacted and non-impacted sides.
