Brief Summary:
The present study aims to evaluate the effect of phototherapy with the combination of different sources of light on pain, activity of temporal and masseter muscles, bilateral and joint mobility in subjects with TMD. It will be made a randomized, placebo-controlled and double-blind clinical trial. Individuals participate with myogenic temporomandibular disorder, being allocated into 4 groups randomly and stratified by the method of sealed envelopes. The results will be evaluated using: RDC/TMD, digital caliper, electromyography, and visual analog scale and algometry. The protocols will be used in a single session and will be evaluated in four different moments. The variables that will be investigated are pain, muscle activity and joint mobility. The analyses of the data will be performed by adopting a significance level of 5%.

Arm Intervention/treatment
Experimental: Phototherapy
Three groups will receive different fototerapia of light sources, and group 1 will not receive dose: Group A (0, 65Joules), Group B (1.30 Joules) and Group C (1.95 Joules) .
Radiation: Phototherapy
Portable Cluster 9 PainAway ® diodes manufactured by Multi Radiance Medical ® (Solon, OH-USA), being 1 905 nm diode (1 mW average power 10 W of peak power, spot of 0.44 cm2), 875 nm diodes 4 (17.5 mW average power for each diode, spot of 1 cm2) and 670 nm diodes 4 (15 mW average power for each diode1 spot, cm2), frequency of 1000 Hz, irradiation time of 300 seconds, energy delivered from 39.3 Joules.

Placebo Comparator: Placebo phototherapy
The volunteers will be subjected to the same Groups intervention Phototherapy . The but researcher will receive placebo pen. It is the caveat that, after completed the voluntary participation, will be held with the active pen treatment.
Radiation: Placebo phototherapy
The volunteers will be subjected to the same Groups ' intervention and placebo pen Phototherapy.

Primary Outcome Measures :
  1. Pain intensity. [ Time Frame: 1 year ]
    Will be used a algometry D-200 of Instrutherm ®, which is a semi quantitative method to measure the intensity of the pain by the pressure, find painful spots, in addition to quantify changes the various pain syndromes.

Secondary Outcome Measures :
  1. Electromyographic activity [ Time Frame: 1 year ]
    The electrical powers of masticatory muscles will be verified in this study through surface electromyography, specifically the masseter and temporal muscles, serving as a useful tool to quantify muscle activity during Mastication and thus identify its functional changes.

Other Outcome Measures:
  1. Analysis of superficial cutaneous temperature [ Time Frame: 1 year ]
    A thermal camera model FLIR T450 ® SC Systems (Stockholm, Sweden) is used to measure the surface skin temperature of the masseter and temporal muscles to verify the effect of phototherapy in them.
