Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
TMD control
Patients with diagnosis of temporomandibular disorder and that are not submitted to pre-fatigue low-level laser therapy
No interventions assigned to this group
TMD LLL
Patients with diagnosis of temporomandibular disorder and that are submitted to pre-fatigue low-level laser therapy
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.
Without TMD control
Patients without diagnosis of temporomandibular disorder and that are not submitted to pre-fatigue low-level laser therapy
No interventions assigned to this group

TMD placebo
Patients with diagnosis of temporomandibular disorder and that are submitted to placebo low-level laser treatment
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.
Without TMD placebo
Patients without diagnosis of temporomandibular disorder and that are submitted to placebo low-level laser treatment
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.
