Effects of low-energy laser in the treatment of myofascial pain dysfunction syndrome of the temporo-mandibular joint

Abstract EN

Background : the aim of this study to evaluate the effectiveness of low-energy 904nm gallium-arsenide laser therapy in myofascial pain dysfunction syndrome of the temporo-mandibular joint.

Materials and methods : Twenty six patients included in this study who complain from myofascial pain dysfunction syndrome of the temporo-mandibular joints.

The patients were randomly divided into two groups.

Group 1 consisted of 13 patients who received non-steroidal anti-inflammatory drug and muscle relaxant for three weeks, and group 2 consisted of 13 patients who received low-energy laser for three weeks.

Results : the study reveals significant early improvement in laser group in reducing pain severity and muscle tenderness from first week up to the end of the observation period.

Conclusion : low-energy laser had an effect at the trigger points and significantly reducing the pain and muscle tenderness.
