Orthodontic treatment may have potential of inducing cervical root resorption

The aim of this systematic review was to investigate whether orthodontic treatment could be considered as a risk factor of cervical root resorption in patients who had undergone fixed appliances therapy. A comprehensive electronic and manual search was conducted in four databases and six journals without any limitations on year of publication. A customized data extraction form was used to retrieve relevant information from each eligible study. Risk of bias was assessed using the Cochrane risk of bias tool (RoB 2) and the risk of bias in nonrandomized studies of interventions tool (ROBINS-I). The quality of evidence was assessed using the grading of recommendations, assessment, development, and evaluation (GRADE) approach. The review included two randomized clinical trials (RCTs) and one cohort study. Risk of bias was assessed as high for both RCTs and critical for the cohort study. Conflicting results were reported by the studies included in this review. Both RCTs reported significant differences between orthodontically moved teeth and teeth that were not moved, while the cohort study reported a lack of association between fixed orthodontic treatment and cervical root resorption. Quality of evidence provided by this review was judged to be of very low quality.
