Influence of Wavelength on the Outcome of the Treatment of TMJ Disorders - TMDS

摘要

It is known that wavelength influences the outcome of many clinical protocols. Laser-phototherapy (LPT) and LEDs have been used on the treatment of pain of several origins including temporomandibular disorders - TMDs. 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, oclusal adjustment, physiotherapy or their association are used. This work reports a series of patients of the Center of Biophotonics of the Federal University of Bahia over 10 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. A.780, λ 790, λ 830nm and/or λ 660 and λ 680nm lasers or LED were used on each session. Most patients were female (～43.6 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 most patients were asymptomatic or improved after treatment and that the association of wavelengths was very efficient on the symptomatic group. It is concluded that the association of both wavelengths was effective on pain reduction on TMJ disorders of several origins.
