This study aimed to evaluate the effect of low-level laser with wavelength of 940 nm on acceleration of orthodontic tooth movement. Materials and Methods: This study was a double-blind randomized-controlled trial with split-mouth design. Fifty-five patients whose four first premolars were extracted for orthodontic treatment were randomly allocated to group A (n = 27) and group B (n = 28). Canine retraction was performed using the force of 150 g in every patient. The patients of group A received active laser irradiation (wavelength of 940 nm, power output of 50 mW, energy of 5 J/cm2) on the right side, no active irradiation on the left side. And those of group B received active laser therapy on the left side, no active irradiation on the right side. Irradiation was performed at two weeks interval. The amount of canine retraction was assessed on dental cast at four weeks interval (T1, T2, T3). And overall canine retraction time was also evaluated. Results: There was a significant difference in the canine retraction rate between laser and placebo groups. At T3, canine retraction speed in laser irradiation side was about 1.6 times faster than that in no laser side. And our results showed that laser irradiation shortened canine retraction time by 21.8% in maxilla and 23.4% in mandible. Conclusion: Low-level laser with wavelength of 940 nm can accelerate the orthodontic tooth movement and reduce the overall treatment time when applied at 2 weeks interval.

Keywords: Orthodontic, laser, canine retraction, tooth movement acceleration, accelerated orthodontics, low-level laser therapy (LLLT).
