Comparative evaluation of different modes of low-level laser therapy on the rate of maxillary canine retraction

The present randomized clinical study was conducted to compare the effect of continues versus pulsated low-level laser therapy on the rate of maxillary canine retraction. Methods: The present study was conducted on 32 maxillary canines of 16 patients had an indication for retraction of maxillary canines using NiTi closed coil springs. The mean age of 21.3 ± 2.25 years. Patients were randomly divided into two main groups according to the mode of application of low-level laser therapy. The amount of canine retraction was assessed via analysis of study models following 3D cast scanning.
