Purpose To determine the correlation between external apical root resorption and malocclusion-related variables in patients treated with fixed orthodontic appliances. Methods In all, 103 patients aged 12–15 years and treated with edge-wise appliances either without extractions or with four premolar extractions were included in this retrospective cohort study. External apical root resorption was assessed in the pre- and posttreatment panoramic radiographs of these patients for incisors, canines, premolars, and first molars. A total of 2332 teeth were evaluated in 206 panoramic radiographs obtained from 103 patients. The gender of the patients, duration of orthodontic treatments, presence of premolar extractions, Angle classification, overbite, overjet and amount of crowding were assessed. Wilcoxon signed-rank test, Mann–Whitney U test, and Kruskal–Wallis test were used for statistical analysis of the data. Results Statistically significant ( p
