Abstract

Background: Recognizing the variable anatomy of the Maxillary Sinus (MS) and its proximity to the developing maxillary canines, this study aimed to evaluate the correlation between MS and maxillary canine root apex in cone beam computed tomography (CBCT).
Methods: In this cross-sectional analytical study all CBCT scans of patients were reviewed retrospectively. Random sampling was used to select the CBCT scans of patients. When the MS extended to the canine area, the vertical distance between them was measured, and their relationship was classified into three types: I (more than 2 mm distance), II (less than 2 mm distance or in-contact), and III (interlock).
Results: Most of the cases of relation between the apex of the canine tooth root and the floor of the maxillary sinus were type 1 (92.9%), followed by type 2a with a frequency of 3.7%, type 3 with a frequency of 2.7% and type 2b with a frequency of 0.7%. The relationship between the apex of the root of the canine tooth and the floor of the maxillary sinus was not significant based on sides (P=0.583), but there was a significant difference based on gender (P=0.025).
Conclusion: In most cases, the MS encroached upon the canine region and occasionally extended into the incisor area. This observation underscores the need for heightened vigilance during surgical interventions involving the maxillary anterior sextant.
