External Root Resorption Associated with Orthodontic Treatment—Descriptive Correlations of Biological and Dental Risk Factors
Abstract
Background/Objectives: External root resorption is an undesirable complication of orthodontic treatment, characterized by the loss of dental root structure. The aim of this study was to identify the biological and dental risk factors involved in the development of external root resorption at the end of orthodontic treatment. Methods: A retrospective observational study was conducted on a sample of 120 patients who underwent orthodontic treatment. External root resorption was assessed using pre- and post-treatment panoramic radiographs. Correlations were established between the severity of external root resorption and various biological and dental risk factors. Results: Out of a total of 2639 teeth analyzed, 52.14% exhibited external root resorption, with most cases being mild to moderate (
