A efetividade da laserpuntura associada a vitamina B12 no tratamento da disfunção temporomandibular e dor orofacial

Abstract

The application of the laser of low-intensity has been described in the literature as a proposal for the treatment of painful conditions of the temporamandibular disorder (TMD), being essential to act based on scientific evidence for a better result in the treatment. This randomized clinical trial aimed to evaluate the efficacy of laser puncture using low-intensity laser in the treatment of pain in patients with temporamandibular disorders and the efficacy of concomitant administration with the treatment of vitamin B13 methylcobalamin. In the first stage of the study, a questionnaire was applied to the participants, which allowed the assessment of the location of orofacial pain. At this same stage, an request for a blood test to measure vitamin B12 was delivered, and the result was delivered in the second stage, so it wouldn't influence the division of the groups. The second stage began with the random division of groups: Group 1: placebo laser puncture and vitamin B12; Group 2: effective laser puncture and placebo vitamin B12 and Group 3: effective laser puncture and effective vitamin B12. Forty-five adult patients (over 18 years old), regardless of gender and race, with signs and symptoms of Temporomandibular Disorder, where pain was the main complaint, participated in this research. In all sessions, before and after the application of laser therapy, the patient was presented with a visual analogue scale (VAS), and the results obtained in each session, were recorded. Laser puncture was applied to traditional Chinese medicine points, used for the treatment of temporomandibular disorders, using the XP laser therapy device, brand DMC, with an infrared wavelength of 3J in each point. There were eight service sessions, two sessions per week, for a total of 4 weeks. The groups B and C showed very effective treatment. Group C, in the third session already had the effective result of the treatment. This proves that laser puncture, when combined with the use of vitamin B12, becomes more efficient, speeding up the treatment process.
