Impacto da fotobiomodulação associada à terapia miofuncional orofacial sobre a qualidade de vida relacionada à saúde oral de indivíduos com disfunção temporomandibular

Abstract

Objective: To analyze the impact of treatment with photobiomodulation associated with orofacial myofunctional therapy on the quality of life related to oral health of temporomandibular disorders, as well as to verify a possible correlation between the degree of orofacial pain and a self-perception of this impact. Method: Study of the randomized, controlled and blinded clinical trial, with 34 volunteers randomly divided into two groups: G1, which includes an Orofacial Myofunctional Therapy (BMT) associated with photobiomodulation and G2, treated by BMT associated with inactive laser. Speech therapy assessment was performed, the degree of orofacial pain using the Visual Analogue Scale (VAS) and the quality of life related to oral health (QVRSO) using the Oral Health Impact Profle - Short form questionnaire (OHIP-14). The data obtained were obtained statistically. The significance level of 0.05 (95%) was adopted. Results: "Physical pain", "psychological discomfort", "physical limitation" and "psychological limitation" were the most impacting aspects in the HRQoL. G1 showed responses to treatment, as did G2. There was a positive and strong correlation for VAS and total OHIP-14 score between groups after treatment. Conclusion: People who received photobiomodulation associated with a BMT, notice an improvement in HRQoL, as well as those treated with the placebo laser. There is a positive and strong correlation between improvement in the degree of pain and self-perception of HRQoL.
