Photobiomodulation therapy in the treatment of temporomandibular disorders
Objective: To report a clinical case using the photobiomodulation in the treatment of the temporomandibular dysfunction providing analgesia and greater buccal opening. Case report: Patient, 24-year-old, female, with temporomandibular dysfunction was treated in the “Laser Therapy in Dentistry” extension project at the Federal University of Maranhão. The diagnosis was made through a careful anamnesis, clinical examination and questionnaire application. The laser device used in the treatment was the low power one whose active medium is composed by a semiconductor diode of Gallium and Aluminum Arsenide (GaAlAs). The protocol used for the treatment was 808 nm wavelength, 60 s, 6 J energy per point, in a total of ten sessions. In the second session, during the evaluation, the patient reported a significant improvement in the degree of pain and the measure of mouth opening ranged from 25 mm to 40 mm. Conclusion: Photobiomodulation has proved to be an effective modality for the treatment of this disorder.
