Brief summary
movement using low-level laser therapy with different wavelengths. Participants will receive laser application during orthodontic treatment, and the rate of canine movement will be measured and compared between the study groups. The results may help determine whether low-level laser therapy can accelerate orthodontic tooth movement safely and effectively.
Detailed description
Photobiomodulation therapy (PBMT) has been proposed as a non-invasive adjunctive method to accelerate orthodontic tooth movement and reduce overall treatment duration. This split-mouth randomized clinical trial aims to evaluate and compare the effectiveness of two different laser wavelengths (650 nm and 976 nm) on the acceleration of maxillary canine movement during orthodontic treatment. Participants requiring bilateral maxillary first premolar extraction and canine retraction as part of their orthodontic treatment will be included. Each patient will serve as their own control using a split-mouth design. One side will receive PBMT application during canine retraction, while the contralateral side will act as the control or receive an alternative wavelength according to the randomization protocol. Orthodontic canine movement will be performed using standardized orthodontic mechanics under controlled force application. The primary outcome measure will be the rate of maxillary canine movement assessed at regular intervals. Secondary outcomes will include total treatment duration required for space closure and the influence of patient-related factors such as age and gender on treatment outcomes. The study will compare the clinical effectiveness of 650 nm and 976 nm wavelengths in accelerating orthodontic tooth movement. Statistical analyses including paired t-tests, independent t-tests, and correlation analyses will be used to evaluate differences between groups and assess associations between demographic variables and treatment response. The findings of this study may provide clinically relevant evidence regarding the effectiveness of PBMT in reducing orthodontic treatment time and improving treatment efficiency.

Masking description
This is an open-label study in which both the investigator and participants are aware of the laser wavelength applied during treatment.
Intervention model description
This study uses a split-mouth randomized clinical trial design in which each participant serves as their own control. Maxillary canine retraction will be performed bilaterally following premolar extraction. Different photobiomodulation therapy wavelengths (650 nm and 976 nm) will be applied according to the randomization protocol during orthodontic canine movement.
