Summary

Temporomandibular disorders (TMDs) are the major cause of non-dental pain in orofacial area. Laser therapy can be considered as one of the most recent treatment approaches in the field of physiotherapy. The special features of laser light such as coherence, monochromaticity, and collimation can result in the ability of laser light to modify cellular metabolism, increase tissue repair and reduce edema and inflammation. Several studies demonstrated successful results regarding the use of low level lasers in releasing pain of musculoskeletal conditions, but there are also contradictory reports in this field, and the clinical effectiveness of this treatment modality has been debated in some review articles. A few studies evaluated the efficacy of low level laser therapy in the treatment of temporomandibular disorders and the associated myofacial pain. There are remarkable variations in the methodology of these researches and some reported insufficient data regarding the physical properties of the laser used. The aim of this study is to evaluate the effectiveness of low level laser therapy in improving the sign and symptoms of patients suffering from myofacial pain syndrome.

Conditions

  • Myofacial Pain Syndrome

Interventions

RADIATION

Low level laser therapy

Ga As diode laser (890 nm) Mustang 2000+, Russia), with frequency of 1500 Hz, and dose of 2 J/cm2 per point in the painful muscles. Laser therapy will be applied on all painful muscles three times a week for four weeks.

RADIATION

Placebo group

In this group, the low power laser will be applied with a minimal dose that is very lower than the threshold necessary for therapeutic effects. Laser therapy will be applied on all painful muscles three times a week for four weeks.
