Fig. 3From: Orthodontically induced external apical root resorption considerations of root-filled teeth vs vital pulp teeth: a systematic review and meta-analysisForest plot of orthodontic root resorption after endodontic treatment and vital pulp teeth. The results of the literature heterogeneity test showed large heterogeneity between studies, so a random effects model was used for analysis. The results of the main effect test showed that orthodontic root resorption of root-filled teeth was lower than that of vital pulp teeth.
