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 ΒΌ 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.
