Resumen

Objective: We aimed to evaluate the efficacy of photobiomodulation (PBM), using an 635 nm diode laser, to provide pain relief for temporomandibular disorder (TMD). Background data: TMD involves a set of multiple clinical manifestations where pain is prevalent. Treatment ideally should be noninvasive and innocuous such as PBM. Methods: A randomized, placebo-controlled, clinically blinded trial was performed on 42 patients with painful TMD diagnosed according the Research Diagnostic Criteria for Temporomandibular Disorders. They were randomly placed into two groups: an intervention group (n = 22) subjected to the application of a 635 nm wavelength diode laser (using a 8-mm diameter handpiece in contact mode, delivering 8 J/cm2 over a period of 20 sec applied over the sensitive points where the pain was reported by the participants) and a placebo group (n = 20) following the same protocol but without laser activation. All patients received four sessions of treatment over 4 weeks. Personal pain perception, nonassisted pain-free maximum mouth opening and tenderness elicited during palpation of muscles were used as primary outcomes, evaluated at baseline and at follow-up 1 month later by blinded, calibrated evaluators. Results: There was a significant reduction in the degree of pain recorded in the laser group after treatment (0.63 ± 0.36) compared with the baseline evaluation (4.59 ± 2.36; p p = 0.007). There were no reported adverse events or side effects among the patients in the intervention group. Conclusions: Our results suggest that PBM using a 635 nm laser was effective on the remission of painful TMD, without complications.
