Apical root resorption is an undesirable, but frequent side effect of orthodontic treatment, Orthodontic tooth movement involves a series of biologic reactions after force application, which makes teeth vulnerable to root resorption It develops when the natural protection of the predentine and odontoblasts in the root canal, or the precementum and cementoblasts on the root surface are damaged or removed.
