Evaluation of the Relationship between Impacted Maxillary Canine Teeth and Root Resorption in Adjacent Teeth: A Cross-Sectional Cone Beam Computed Tomography Study

This study aims to determine the position of impacted maxillary canines on cone beam computed tomography (CBCT) images, to determine the presence of resorption in adjacent teeth, and to investigate the position and type of resorption of impacted canines if resorption is present. Patients over 14 years of age with maxillary canine teeth who had CBCT images taken for any dental reason were included in the study. Resorption of teeth adjacent to maxillary canines was analyzed according to transversal, vertical, and buccopalatinal positions on the CBCT. The study evaluated 162 maxillary canine teeth on tomography images of 134 patients. Of the affected adjacent teeth, 32.1% of the central incisor, 58.0% of the lateral incisor, and 19.1% of the first premolars showed mild-to-severe resorption. The relationships between transversal position and resorption in the central and lateral incisor, vertical position and resorption in the central incisor and buccopalatinal position and resorption in the first premolars were found to be significant. Maxillary canine teeth can cause mild-to-severe resorption of adjacent teeth, especially lateral incisors. For this reason, we think that a detailed examination with CBCT is essential in the early diagnosis of resorption of adjacent teeth.
