Clinical Trial Summary

Temporomandibular Dysfunction - TMD is considered the main cause of orofacial pain of non-dental origin, and a public health problem. Due to their complexity there are already treatments using various forms of therapy. Photobiomodulation using different light sources, in a single or combined form, makes it possible to use it as another therapeutic resource to be explored. The objective of this study will be to evaluate the effects of photobiomodulation with simultaneous use of light emitting diodes (LEDs), red and infrared, on clinical aspects in individuals with TMD. A randomized, controlled and blind clinical trial is proposed, which will involve 33 individuals (n = 11 per group) of both genders, aged 18-45 years in three groups: Group 1 - LED; Group 2 - placebo and Group 3 - control, submitted to 6 nonconsecutive sessions of photobiomodulation totaling 2 weeks of treatment. The Research Diagnostic Criteria for Temporomandibular Disorders - RDC/TMD will be used to determine the TMD and evaluate the participants. Pain will be assessed using the visual analog scale (VAS), mandibular range of motion will be determined with the aid of a digital caliper, and the electrical activity of the masticatory muscles will be verified by electromyography. A mixed plate of 18 red LEDs - 660 nm and 18 infrared LEDs - 850 nm with power of 3.5 mW per LED, 4.45 mW/cm2, radiant exposure of 5,35 J/cm2, irradiated area of 14.13 cm2, and energy of 75.6 J, in the temporomandibular joint (TMJ) region and in the masseter and temporal muscles, bilateral in 6 sessions. Participants from all groups will be reassessed after the first therapeutic intervention, and again at the end, following the same evaluation procedures used initially.
