Photobiomodulation and Lasers

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.
