Purpose
This article aims to highlight the role of low-level laser therapy (LLLT) in accelerating tooth movement during orthodontic treatment.
Methods
Search engines “PubMed” and “Google Scholar,” and data from electronic journals, which are “Photomedicine and Laser Surgery Journal,” “Angle Orthodontics,” “Dental Research Journal,” and “American Journal of Orthodontics and Dentofacial Orthopedics,” were compiled and analyzed. Articles were searched from Jan 2011 to Jan 2022, using the following keywords: Low-Level Laser therapies, LLLT, Orthodontic tooth movement, dental movement.
Results
Seven out of ten human clinical trials cited in this study used LLLT with different laser parameters, in which their results showed an increase in the speed of orthodontic tooth movement when compared to the placebo or control groups. However, there are three studies that do not demonstrate any benefit.
Conclusion
The results of this study suggest that the application of photo-biomodulation therapy could significantly accelerate orthodontic movement; however, more histological studies must be performed to better understand the biological effects of the device.
