The relationship between orthodontic bracket systems and external root resorption has remained debatable. Objective: This study compared the magnitude and pattern of the external root resorption of maxillary incisors as induced by self-ligating and conventional bracket systems via cone beam computed tomography and medical imaging programs. Methods: Eight participants were recruited for each bracket system. Their maxillary incisors were scanned at the beginning (T0) and 18 months into treatment (T1). Three-dimensional models of the four maxillary incisors at T0 and T1 were reconstructed using the Mimics program. The difference in root length between T0 and T1 models represented external root …
