Abstract

Temporomandibular disorders - TMDs are common painful multifactorial conditions affecting the temporomandibular joint whose treatment depends on the type and symptoms. Initially it requires pain control and for this, drugs, biting plates, occlusal adjustment, physiotherapy or their association are used. Laser-phototherapy (LPT) has been used on the treatment of pain of several origins including TMDs. It is known that wavelength, energy density, frequency of application influences the outcome of many clinical protocols. This work reports a series of patients of the Center of Biophotonics of the Federal University of Bahia over 15 years. Following standard anamneses, clinical and imaginologic examination and with the diagnosis of any type of TMD, the patients were set for light treatment. Treatment consisted of three sessions a week during six week. Prior irradiation, the patients were asked to score their pain using a VAS. IR and/or Red diode lasers were used on each session. The medical records of 432 patients (73 male and 359 female) suffering from TMJ disorders were revised. Most patients were female (~47.9 years old). At the end of the 12 sessions the patients were again examined and score their pain using VAS. No other intervention was carried out during the treatment. The results were statistically analyzed and showed that 51.16 % of the patients were asymptomatic or improved after treatment. It is concluded that LPT was effective on pain reduction on TMJ disorders of several origins.
