Summary
Low-level laser therapy (LLLT) improves periodontal health and speeds up orthodontic tooth movement in patients with compromised periodontium. This adjunctive treatment also significantly reduces patient-reported pain during orthodontic therapy.
Area of Science:
- Periodontology
- Orthodontics
- Biomedical Engineering
Background:
- Periodontal disease complicates orthodontic treatment, affecting both oral health and treatment outcomes.
- Low-level laser therapy (LLLT) shows promise as an adjunctive method for improving periodontal healing and orthodontic tooth movement.
Purpose of the Study:
- To evaluate the efficacy of LLLT as an adjunct to orthodontic treatment in periodontally compromised patients.
- To assess the impact of LLLT on periodontal indices, tooth movement rate, and pain levels.
Main Methods:
- A randomized controlled trial involved 60 periodontally compromised patients.
- Participants received either standard orthodontic treatment with LLLT or standard orthodontic treatment alone.
- LLLT was administered at 810 nm, 5 J/cm², for 10 minutes per session, twice weekly for 8 weeks.
Main Results:
- The LLLT group demonstrated significant improvements in periodontal indices, including a greater reduction in probing depth (2.3 mm vs. 1.2 mm).
- Orthodontic tooth movement was accelerated in the LLLT group (1.5 mm/month vs. 1.0 mm/month).
- Patients receiving LLLT reported significantly lower pain levels (3.2-point reduction vs. 1.8-point reduction).
Conclusions:
- LLLT significantly enhances periodontal health in patients undergoing orthodontic treatment.
- LLLT accelerates the rate of orthodontic tooth movement.
- LLLT effectively reduces pain associated with orthodontic treatment in periodontally compromised individuals.
