Objective. To determine the photobiomodulatory effect of low-power laser on pain and tooth movement in adult patients with fixed orthodontic treatment. Methods.  Parallel randomized controlled clinical trial, approved by the Ethics Committee of the PNP “Luis N. Sáenz” National Hospital. The sample included 24 patients from the Orthodontic Service in need of canine distalization treatment due to extraction of first premolars divided into experimental and control groups. The experimental group (12) was treated with a distalization device and Therapy EC (DMC) laser, λ: 808 nm and 100 Mw, at 10 irradiation points: vestibular (05) and palatal (05) in the cervical root third, third middle root, apical root third, bony crests of the canine (mesial and distal) in doses of 2J for 20 seconds per point. Irradiations occurred when the distalizer was activated, at the 1st, 2nd, 3rd and 4th week.  The control group is treated with the distalization device and simulated and inactive laser treatment. Results. The laser reduced pain in the experimental group by (4.5 ± 1.50) VAS points compared to the control group (2 ± 1) points from T0 to T4. Likewise, for tooth movement, the distance traveled by the canine in the Experimental Group (2.50 mm ± 0.70) was greater than in the Control Group (0.45 mm ± 0.25). The differences were statistically significant (p<0.05), U-Mann Whitney test. Conclusions. The low-power laser reduced the pain associated with orthodontic treatment and accelerated tooth movement.
