This randomized controlled clinical trial investigated the effect of micro-osteoperforation (MOP) on external apical root resorption (EARR) of maxillary incisors during orthodontic retraction. Utilizing Cone-Beam Computed Tomography (CBCT), the study aimed to clarify MOP's safety concerning EARR, a common complication of orthodontic treatment. Fifty patients were enrolled, with 25 in the MOP group receiving perforations to enhance tooth movement. Results showed a significant increase in incisor retraction rate in the MOP group (1.2 mm/month) compared to the control group (0.8 mm/month), but no significant differences in root length or volume reductions between groups. Most teeth exhibited mild resorption, with no severe cases observed. The study concluded that MOP accelerates tooth movement without significantly increasing EARR risk, supporting its use as a safe adjunctive technique in orthodontics.
