    Area of Science:

    • Orthodontics
    • Biomedical Engineering
    • Regenerative Medicine

    Background:

    • Photobiomodulation, using low-level laser therapy (LLLT), is explored for its non-invasive potential in orthodontics.
    • LLLT is known to stimulate tissue growth, regeneration, and reduce inflammation and pain.
    • Research investigates LLLT's impact on bone remodeling to influence orthodontic tooth movement rates.

    Purpose of the Study:

    • To evaluate the efficacy of photobiomodulation (LLLT) in accelerating orthodontic tooth movement.
    • To assess the influence of LLLT on bone remodeling processes relevant to tooth movement.
    • To determine the effect of LLLT on post-adjustment pain in orthodontic patients.

    Main Methods:

    • Review of recent research projects testing the effects of laser therapy on bone remodeling and tooth movement.
    • Analysis of studies examining LLLT's impact on tissue growth, regeneration, inflammation, and pain.
    • Comparison of outcomes based on varying LLLT dosages and treatment protocols.

    Main Results:

    • LLLT demonstrated a proven effect in reducing post-adjustment orthodontic pain.
    • Results regarding the acceleration of tooth movement are diverse, with some studies showing acceleration and others not.
    • Low-dose LLLT appears to increase tooth movement, while high-dose LLLT may have inhibitory effects.

    Conclusions:

    • Further research is necessary to establish optimal LLLT protocols for beneficial effects on bone remodeling and orthodontic tooth movement.
    • The findings suggest LLLT could be a valuable adjunct in orthodontic treatment, but requires precise application.
    • Standardization of LLLT parameters is crucial for its successful implementation in daily orthodontic practice.
