The aim of the present study was to compare, a standard efficient technique in accelerating OTM as surgical corticotomy as a gold standard versus surgical corticotomy combined with LLLT in an attempt for further acceleration of OTM.
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.

Corticotomy is carried out under local anesthesia followed by low-intensity laser therapy that is started on the selected experimental side on the same day as placement of the coil spring
Corticotomy is carried out under local anesthesia in right side.
Rate of canine retraction
Rate of canine retraction using a digital caliper, units of mm, readings extracted from digital models reading each month.
Time frame: 4 months
Root resorption
Root resorption using CBCT in mm after the end of canine retraction period (at the end of 4 months)
Time frame: after 4 months from start of clinical trial
