Antimicrobial photodynamic therapy (aPDT) is a treatment option to reduce pathogenic microorganisms such as bacteria, viruses, and fungi and can be effective in dental stomatitis (DS), because a complex polymicrobial biofilm can proliferate on the denture surface, and Candida spp. is one of the most relevant agents. The aim was to report the case of an 83-year-old edentulous man, denture user, with DS. A microbiological exam identified cfu/mL of Candida spp. Then, 5 sessions of aPDT with 0.01% methylene blue solution and a red laser source (aluminium indium gallium phosphide, 660 nm, 9 J output energy, fluence of 300 J/cm2, 100 mW output power, irradiance of 3.33 W/cm2, 90 seconds) were performed. After 5 weeks of aPDT, there was remission of DS and reduction of in colony-forming units per milliliter of fungi and Candida spp. aPDT can be an effective therapy in DS associated with Candida spp.
