Summary

The objective of this study is to perform an evaluation of the effect of LLLT on the prevention of fatigue in the masseter and anterior temporal muscles in young individuals with and without TMD.

Conditions

  • Temporomandibular Joint Disorders

Interventions

DEVICE

low-level laser therapy

Three points will be irradiated over the masseter muscle (upper, middle and lower bundles) and one point will be irradiated over the anterior temporal muscle of each side of the face in the groups submitted to pre-fatigue laser. The following parameters will be employed: wavelength: 780 nm; energy density: 25 J/cm2; output power: 50 mW; power density: 1.25 W/cm2; and exposure time: 20 seconds per points, resulting in a total energy of 1 J per point. The laser will be applied punctually with a conventional tip in contact with the skin considering an area of 0.04 cm2.

OTHER

Placebo comparator

The same equipment will be used in the placebo group, but with a pen that emits a red guide light and a warning sound, but without the emission of a laser beam.
