It usually affects individuals between the 4 th and 5 th decade of life, mainly women, seven times more often than men 2 2. Burning mouth syndrome: differential diagnosis. Nevertheless, there were positive results in some statistical analyses, thus encouraging further research in BMS laser therapy with other irradiation parameters.īurning Mouth Syndrome Laser Therapy Glossalgiaīurning mouth syndrome is a distinct nosological entity characterized by a chronic idiopathic burning sensation that affects the oral cavity mucosa, without presenting any local clinical signs or detectable laboratory alterations 1 1. According to the protocol used in this study, low intensity laser therapy is as beneficial to patients with BMS as placebo treatment, indicating a great emotional component of involvement in BMS symptomatology. The results were categorized according to the percentage of symptom level variation, and showed a statistically better response in LG in only two categories of the control checkpoints (p=0.02 Fisher’s Exact Test). Both researchers were blinded, the first to the results, and the second to the type of radiation applied. One researcher delivered irradiation and another recorded the results. A visual analogue scale (VAS) was used to assess the therapeutic effect before and after each irradiation, and at all the control time periods: 7, 14, 30, 60 and 90 days after the last irradiation. Infrared laser (AsGaAI) irradiations were applied to the affected mucosa in scanning mode, wavelength of 790 nm, output power of 20 mW and fluence of 6 J/cm 2. Each patient received 4 irradiations (laser or placebo) twice a week, for two consecutive weeks (blinded to the type of irradiation received). Seven patients dropped out, leaving 13 patients in LG and 10 patients in CG. Thirty BMS subjects were randomized into two groups – Laser (LG) and Placebo (CG). The aim of this study was to assess the effectiveness of low intensity laser therapy in patients with Burning Mouth Syndrome (BMS).
