Tongue scraper group (Group 1)
aPDT group (Group 2)
Tongue scraper and aPDT (Group 3)
Fifteen patients will be included in this group. Tongue scraping will be performed by the same operator in all patients. Posterior-anterior movements will be performed with the scraper over the lingual dorsum, followed by cleaning the scraper with a gauze. This procedure will be performed ten times in each patient, in order to standardize the mechanical removal of the tongue coating.
Fifteen patients will be included in this group. One session of aPDT will be performed with the photosensitizer (PS) urucum manipulated at a concentration of 20% (Fórmula e Ação®) in spray, to be applied in sufficient quantity to cover the middle third and back of the tongue (5 sprinkles) for 5 minutes for incubation. The excess will be removed with a sucker in order to keep the surface wet with the PS itself, without using water. Six points with a distance of 1 cm between them will be irradiated, considering the halo of light scattering and effectiveness of aPDT. The apparatus shall be precalibrated at wavelength 440-480nm for 60 seconds per point, irradiance of 450mW/cm and the light shall be irradiated so that a halo of 2cm diameter is formed per point.
