Abstract

Background: Maxillary canines are the second most frequently impacted teeth after the third molars. Bucco-palatal localization is the primary diagnostic task during radiographic examination of impacted maxillary canines for proper treatment planning. Such localization is done by a combination of clinical and radiographic findings. However, it is necessary to identify cases requiring 3D cone-beam computed tomography (CBCT) scans in addition to 2D orthopantomograms (OPG) for accurate diagnosis.
Materials and Methods: OPG and CBCT images of 75 impacted maxillary canines (IMC) were included in the study. Each OPG was evaluated for magnification index. The data obtained was tabulated and subjected to statistical analysis.
Results: The present study revealed a higher prevalence of impacted maxillary canines in females (73%), with a slightly higher prevalence on the left side (53%). Most of the impacted canines were present in the mid-alveolus region. All the cases had 100% concordance between OPG and CBCT while locating palatal and mid-alveolar impacted canines whereas for buccally impacted canines, the concordance between OPG and CBCT was 93%.
Conclusion: Early radiographic examination and diagnosis are essential to recognize impacted maxillary canines. The sequela of delayed eruption or treatment of impacted canines may be severe resorption of the adjacent lateral and central incisors.
