Abstract: Background: The primary objective of this trial was to evaluate the supplementary effect of photobiomodulation when added to orofacial myofunctional therapy on symptoms of Temporomandibular Disorder (TMD) in TMD. Materials and Methods: This pilot randomized trial investigated the effects of photobiomodulation on TMD symptoms. Eleven women with mild to moderate TMD were randomly assigned to either an experimental group (EG, n=5) receiving photobiomodulation combined with orofacial myofunctional therapy or a control group (CG, n=6) receiving passive orofacial myofunctional treatment alone. Participants underwent 12 sessions of treatment, with photobiomodulation administered using an 830nm laser at 48J/cm2 fluence. Outcome measures included pain levels and oral health-related quality of life. Results: The experimental group had considerably greater readings for all motions, including protrusion (P=0.037), sides (P=0.0025; P=0.0014), and opening (P=0.039), according to an examination of the groups. The control group's findings were statistically significant only for the measurements on the left and right (P=0.0030 and 0.0026, respectively). Numerous traits associated with mandibular mobility showed a discernible improvement before and after therapy in the EG. These variables include noise at the right and left temporomandibular joint (TMJ) during opening and closing of the mouth (P=0.019), noise at the right and left TMJ during protrusion (P=0.147; P=0.049), noise at the right and left TMJ during opening of the mouth (P=0.028; P=0.038), and noise at the left TMJ during opening of the mouth (P=0.012). There was only a reduction in left-sided pain (P=0.019) for the control group when comparing mandibular movements before and after treatment. Conclusion: In conclusion, photobiomodulation treatment improved orofacial myofunctional therapy results, which increased speech therapy's efficacy in treating temporomandibular disorders.
