Abstract

Introduction. The objective of this study was to compare the effects of low-level laser therapy (LLLT), 660nm laser with 830nm, in temporomandibular dysfunction (TMD).

Aim. To compare the effect of LLLT 660 nm and 830 nm in treatment of TMD.

Material and methods. This is a randomized clinical study, composed of 30 volunteers with TMDs selected and divided into three groups: LLLT 660nm, LLLT 830nm and Sham. After the intervention, the results were reevaluated with the Fonseca anamnestic questionnaire (FAQ), American Academy of Orofacial Pain Questionnaire (AAOPQ), McGill Pain Questionnaire and Visual Analog Scale.

Results. Analysis of the results showed that, although all groups had reduced values in the FAQ, only the laser groups presented alterations in the level of classification; for AAOPQ, only the treatment groups had a reduction in the positive responses, variables, the reduction was similar for all groups.

Conclusion. LLLT produced a reduction in severity of symptoms but was like the sham for pain.
