Evaluation of the Effect of Corticotomy and Low Level Laser Therapy on Orthodontic Tooth Movement

The study design was a randomized split mouth design to compare, clinically and radiographically, between the two interventions (Corticotomy and Laser versus Corticotomy only) by assessing the rate of maxillary canine retraction achieved in 4 months. Secondary outcomes were to evaluate 1st maxillary molar anchorage loss, changes in tipping, torque and rotations values of maxillary canine and 1st molar. In addition, the impact of both interventions on root resorption was assessed. The present study was carried on 16 female patients. All patients required maxillary 1st premolar extraction and subsequent maxillary canine retraction.
