Influencing Factors of Orthodontic Treatment on Root Resorption of Root Canal Therapy

doi:10.13701/j.cnki.kqyxyj.2020.05.013

Abstract

Abstract: Objective: To study the effect of fixed orthodontic treatment on root resorption after root canal therapy and related factors. Methods: 96 patients with complete intraoral root canal treatment before orthodontic fixed treatment were selected. Cone beam computed tomography (CBCT) before and after orthodontic treatment was used to measure the length of root resorption after orthodontic treatment and to analyze the influence factors of orthodontic treatment on root resorption. Results: After orthodontic treatment, the root resorption of root canal therapy teeth was less than that of contralateral living pulp teeth of the same name (P<0.001). Gender was not a factor influencing root resorption in root canal therapy after orthodontic treatment (P＞0.05). Age was a factor influencing root resorption in root canal therapy after orthodontic treatment (P<0.05). The risk of root resorption in adults was greater than that in children. Dental position was a factor influencing root resorption in root canal therapy after orthodontic treatment (P<0.001). And the risk of root resorption in anterior teeth was greater than that in posterior teeth. Conclusion: The risk of root resorption in root canal therapy teeth is lower than that in contralateral living pulp teeth. Age and tooth position are the influencing factors of root resorption in root canal therapy teeth after fixed orthodontic treatment.
