Aim and Objective: Sector position of Impacted Maxillary Canine (IMC) has long been used as prognostic criteria. This study aimed at finding relationship of sector position with other radiographic parameters used to describe position of IMC .
Materials and Methods: A retrospective cross-sectional study was conducted. Patients’ demographic data, OPGs and CBCT records from 2015 to 2020 were obtained from departmental archive of Dr R Ahmed Dental College & Hospital. Measurements done on the panoramic image were as follows: angulation of long axis of IMC with midline (Angle A), angulation with Occlusal plane (Angle B), vertical height of crown from occlusal plane (in ordinal scale). Sector position also was determined from OPG. Labiopalatal position was determined from CBCT images of maxilla.
Results: A total of 100 impacted canines were studied from 82 OPGs fulfilling inclusion criteria of which labiopalatal position can be ascertained in 89 cases. The Chi-square(χ2) test was carried out to analyze the categorical variables that showed higher sectors are associated with higher vertical levels, increased angulation and palatal displacement. The P value of ≤ 0.05 was considered as the level of significance.
Conclusion: IMC with higher sector position is most likely to be associated with increased angulation with midline, greater depth from occlusal plane and palatal position. Labiopalatal position of IMC is associated with sector position and angulation but a definite value or range of these parameters could not be determined that will precisely predict labial or palatal position.
