Cone beam computed tomography (CBCT) assessment of incisor root resorption (IRR) associated with impacted maxillary canines (IMC). Literature review

Abstract

CBCT assessment of impacted canine improves canine localization to adjacent teeth and provides higher level of confidence in the treatment plan compared to 2D images. However, there is conflicting evidence to support using CBCT as a routine first-line imaging method in patients with impacted maxillary canine and incisor root resorption. Consequently, there are doubts regarding difference in diagnostic and treatment planning between the use of conventional 2D and CBCT sets. Therefore, the present review will attempt to summarize the new aspects regarding the benefits of three-dimensional (3D) diagnostic techniques (cone-beam computed tomography, CBCT), including the accuracy of localization of impacted canine and the detection of the degree and location of root resor ption of maxillary incisors.
