Increased pain and/or discomfort during chewing, speaking, and swallowing have been commonly reported by patients with Temporomandibular Dysfunction (TMD). Speech-language pathology therapy (orofacial myofunctional therapy - OMT) has been proposed as part of the treatment for this condition; however, it is a modality that should be introduced when the TMD context and the pain are not accentuated, so that they do not prevent or hinder the performance of exercises. The aim of this study was to analyze the effect of OMT on the treatment of patients with TMD, according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), after analgesia with low-level laser therapy (LLLT), regarding orofacial myofunctional conditions (OMC) and the perception of TMD symptoms. Five patients aged 50 to 61 years were evaluated 30 days after completion of LLLT. An experienced speech-language pathologist conducted, pre- and post-OMT, the application of the ProDTM Multi-questionnaire - to investigate the self-perception of TMD symptomatology, and the Orofacial Myofunctional Evaluation with Scores (OMES) clinical examination - to confirm the orofacial myofunctional conditions. OMC presented increased OMT scores, indicating an increase in myofunctional orofacial balance. According to the patients' perception, TMD signs and symptoms were relieved after the application of OMT. According to the self-perception of the treated patients, introduction of OMT after LLLT analgesia promoted a balance of the orofacial functions of the sample studied, as well as a decrease in the remaining TMD signs and symptoms.
