Aims:This study investigated the efficacy of low-level laser therapy (LLLT) for management temporomandibular joint (TMJ) osteoarthritis.Methodology:In a double-blind clinical trial, 20 patients with TMJ osteoarthritis were randomly divided into and placebo groups. The in group received irradiation from an 810 nm (Peak power 80 W, average 50 mW, 1500 Hz, 1 μs pulse width, 120 seconds, 6 J, 3·4 J/cm2 per point), which was applied on four points around TMJs painful muscles three times week 4 weeks. In group, treatment same as that but simulation. evaluated before (T1), after (T2) 12 (T3) applications month last application (T4), amount mouth opening pain intensity recorded.Results:No significant differences found either between groups or different evaluation each (P>0·05). There no difference symptoms masticatory (P>0·05), some within-group improvements present Visual Analogue Scale (VAS) scores body masseter both groups.Conclusions:LLLT using parameters more effective than reducing improving osteoarthritis.
