Resumo
Objective: The aim of this study was to investigate the effect of low-level laser therapy (LLLT) on the treatment
of burning mouth syndrome (BMS). In addition, the laser effect was compared on the different affected oral sites.
Materials and Methods: Eleven subjects with a total of 25 sites (tongue, lower lip, upper lip, and palate) affected
by a burning sensation were selected. The affected areas were irradiated once a week for three consecutive weeks
with an infrared laser (l ¼ 790 nm). The probe was kept in contact with the tissue, and the mucosal surface was
scanned during the irradiation. The exposure time was calculated based on the fluence of 6 J/cm2
, the output
power of 120 mW, and the area to be treated. Burning intensity was recorded through a visual analog scale
before and after the treatment and at the 6-week follow-up. The percentage of the improvement in symptoms
was also obtained. Results: Burning intensity at the end of the laser therapy was statistically lower than at the
beginning ( p < 0.01). Patients reported an 80.4% reduction in the intensity of symptoms after laser treatment.
There was no statistical difference between the end of the treatment and the 6-week follow-up, except for the
tongue site. Conclusion: Under the investigated parameters, infrared LLLT proved to be a valuable alternative
for BMS treatment, providing a significant and lasting reduction in symptoms.
