The Prevalence of Root Resorption after Orthodontic Treatment in Patients Attending a University Hospital Dental Clinic.

Introduction: After orthodontic treatment, some teeth undergo external root resorption due to different factors, such as the root shape, oral habits, biological and genetic factor, gender, and age. Furthermore, extraction cases, long treatment duration, and the amount of force applied during the treatment might be related to root resorption.

Materials And Methods: Panoramic radiographs for 226 patients treated in the orthodontic department were screened.
