U.S., March 10 -- ClinicalTrials.gov registry received information related to the study (NCT07458139) titled 'Comparison of Root Resorption in Modified Corticotomy-Assisted and Conventional Canine Retraction' on March 03.

Brief Summary: This randomized controlled clinical trial will compare external apical root resorption in patients undergoing maxillary canine retraction using modified corticotomy-assisted frictionless T-loop mechanics versus conventional frictionless T-loop mechanics. Sixty orthodontic patients requiring extraction of maxillary first premolars will be randomly assigned to two groups. Changes in canine root length will be measured on panoramic radiographs taken before and after retraction to determine the extent of extern...
