Placebo

Patients in the placebo group received the same treatment during the same time, but in this case the laser tip produced no light. Placebo (DMC, São Paulo, Brazil): The placebo (DMC, São Paulo, Brazil) was daily applied by a dentist and touched the mucosa of the lips, right and left buccal mucosa, left and right lateral tongue border, buccal floor and ventral tongue, totaling nine points per region.Patients in the placebo group received the same treatment during the same time, but in this case the laser tip produced no light.

Low Level Laser Therapy

The investigators used a diode laser (DMC, São Paulo, Brazil) InGaAlP (indium phosphide, gallium and aluminum), with 100 mW, 4J/cm ², with an area of 0.24 cm ². The laser was daily applied by a dentist and touched the mucosa of the lips, right and left buccal mucosa, left and right lateral tongue border, buccal floor and ventral tongue, totaling nine points per region.
