Effectiveness of Lasers on Accelerating Tooth Movement in Orthodontics

New Rochelle, NY, April 12, 2021—Photobiomodulation, or low-intensity laser therapy, is sometimes used to accelerate tooth movement in orthodontics. A new systematic review and meta-analysis found insufficient evidence to support this treatment, according to a study published in the peer-reviewed journal Photobiomodulation, Photomedicine and Laser Surgery.

Wensheng Ma, Hebei Medical University, and coauthors evaluated nine randomized controlled trials from the literature. In each, the first premolars were extracted and photobiomodulation was used to try to accelerate the movement of the teeth in the treatment group, compared to the control group. Comparisons were made at one, two, and three months. There was no significant difference in cumulative tooth movement at one month in the photobiomodulation group when compared to the control group. There was a significant difference between the two groups at two months. A nonsignificant difference was found between the two groups at three months.
The authors concluded that “There is insufficient evidence to support that photobiomodulation accelerates tooth movement in orthodontic treatments. More large-sample multicenter clinical trials carried out in similar settings are required to confirm and pinpoint treatment efficiency and optimal parameters.”
“Although this systematic review did not find convincing evidence of effectiveness, there were encouraging trends that could be confirmed by larger controlled trials,” says Michael R. Hamblin, PhD, Distinguished Visiting Professor, University of Johannesburg.
