Abstract

Purpose of this investigation is to evaluate efficacy of low level laser therapy (LLLT) on reduction symptoms in patients with burning mouth syndrome (BMS). Etiology of BMS is most likely multi causal, and current treatment possibilities are of limited value. In this study, we performed treatment on 40 patients with BMS average age was 68 yrs (age range 57-85 yrs). The investigation was single blind – placebo controlled. The first (study) group, consisting of 20 BMS patients, was treated by active laser. The control (placebo) group, consisting of another 20 BMS patients, underwent treatment with inactive laser. In the study group we used red diode laser with an emission of 685 nm. Irradiation dose was 2 J/cm², frequency 4, 56 Hz, output 30 mW. The therapy was performed 5 times a week during 2 weeks (all together 10 treatment sessions). Treatment effect was evaluated by visual analogue scale. In both groups symptoms were significantly reduced compared to the pre-treatment period (Friedman ANOVA and “post hoc” Wilcoxon matched pair test, p<0.05), but there were no significant differences in symptom reduction between the study and placebo group (Mann-Whitney U-test, p>0.05). Our data suggest that LLLT acts as a successful placebo in BMS patients.
