What the trial is, and whether it could suit you

This study aims to compare the effects of diode laser and light-emitting diode (LED) photobiomodulation on maxillary canine retraction during fixed orthodontic treatment. Participants requiring bilateral maxillary first premolar extraction will receive both interventions using a split-mouth design. One maxillary canine will receive diode laser photobiomodulation, while the contralateral maxillary canine will receive LED photobiomodulation. Maxillary canine movement will be evaluated at 4, 8, 12, and 16 weeks during retraction to compare the amount and rate of tooth movement between the two interventions. Pain associated with orthodontic tooth movement will also be assessed. Pulp oxygen saturation (SpO₂) of the maxillary canines will be measured to evaluate changes in pulpal oxygenation during orthodontic canine retraction. SpO₂ will be assessed at baseline and at predefined follow-up t
