Summary
Low intensity laser therapy (LILT) effectively reduced pain in patients with temporomandibular disorder (TMD). This randomized, double-blind study found significant pain reduction with active laser treatment compared to placebo.
Area of Science:
- Biomedical Engineering
- Pain Management
- Dental Research
Background:
- Temporomandibular disorder (TMD) is a common condition causing facial pain.
- Effective pain management strategies for TMD are crucial for improving patient quality of life.
Purpose of the Study:
- To evaluate the efficacy of low intensity laser therapy (LILT) for controlling pain associated with temporomandibular joint (TMJ) disorders.
- To compare LILT's effectiveness against a placebo in a randomized, double-blind setting.
Main Methods:
- A randomized, double-blind study involving 48 patients with TMJ pain.
- Treatment involved infrared laser application (780 nm) twice weekly for four weeks, with an active or placebo probe.
- Pain intensity was measured using the Visual Analogue Scale (VAS) via palpation at multiple time points.
Main Results:
- Patients receiving active LILT showed a significant decrease in pain levels compared to the placebo group.
- The most substantial pain reduction was observed after the 8th treatment session.
- Reduced sensitivity to palpation indicated improved pain control.
Conclusions:
- Low intensity laser therapy is an effective treatment modality for managing pain in individuals with TMD.
- LILT offers a promising non-invasive option for pain relief in temporomandibular disorders.
