Abstract
Introduction: The structural characteristics of unilaterally impacted maxillary canines and adjacent teeth were compared to the nonimpacted side. Three-dimensional (3D) cone-beam computed tomography (CBCT) was used to analyze and evaluate the various parameters. The aim of this study was a quantitative comparison of teeth adjacent to buccally and palatally impacted maxillary canines. Methods: CBCT records of 40 patients with unilateral impacted maxillary canine were allocated to this study. The morphological characteristics of teeth on the impaction and non-impaction sides of the same patient were examined. 3D reconstructed CBCT images were assessed using the OnDemand 3D program. Results: The dependent samples t test was used for data analysis with a level of statistical significance of 0.05. There was a significant increase in the size of the maxillary canine crown and a decrease in the maxillary lateral incisor root dimensions on the impacted side. No significant difference was observed in the morphology of the maxillary first premolar on either side. Conclusion: The impacted canine showed greater size compared to the eruption side. The decrease in root dimensions of the lateral incisor on the impacted side may indicate the possibility of root resorption.
