Abstract

Abstract: Objective: To establish an equation to predict the incisors root resorption caused by impacted canines using two-dimensional radiography and cone-beam computed tomography (CBCT). Methods: Objects complying with relevant standard were collected. Subjects were divided into incisor root resorption group and non-resorption group according to the resorption condition of adjacent incisors. Each patient took panoramic radiograph, lateral cephalometric radiograph, and CBCT. Results: The indicators related to incisors root resorption was identified, and then the prediction equation was established according to the results. Conclusion: The incisors root resorption caused by impacted maxillary canines can be explored by the measurements of panoramic radiograph and lateral cephalometric radiograph. The high accuracy rate of central incisors prediction equation indicates that the equation can guide clinical practice. However, the low accuracy rate of lateral incisors prediction equation implies negative information.
