Effect of Different Angulations of Impacted Maxillary Canine on Root Resorption of adjacent teeth Using Cone Beam Computed Tomography: A Retrospective Study.

Abstract

Introduction: Permanent maxillary canine impaction is a common problem. Impacted canines can cause variable degrees of resorption on the roots of surrounding teeth, particularly the lateral incisors . Aim: The objective of this study was to evaluate the effect of different angulations of impacted maxillary canine on root resorption of adjacent teeth using cone-beam computed tomography (CBCT). Materials and Methods: The sample included 30 CBCTs presenting with unilateral or bilateral impacted maxillary canines, ranging in age from 15 to 30 years that were collected. from the Department of Radiology, Faculty of Dentistry, Suez Canal University. Canine angulation relative to the maxillary occlusal plane and adjacent lateral incisor was measured, as well as the locations of the impacted canines. Results: The results of the current study showed (58.8 %) with slight resorption and (26.5%) with moderate resorption of lateral incisor root. There was a statistically significant relationship between root resorption severity and angulation of impacted maxillary canine relative to the lateral incisor. The angle of the impacted maxillary canine with the occlusal plane can`t solely rely on determining the severity of root resorption (RR). Conclusion: RR occurs due to the proximity of the impacted maxillary canine to the adjacent lateral incisor
