This study evaluated the effects of photodynamic therapy (PDT) on buccal candidiasis in mice and on the adherence of yeast to buccal epithelial cells (BECs) in vitro.Study Design. A total of 56 immunosuppressed mice with buccal candidiasis were subjected to PDT, consisting of treatment with erythrosine (400 mu mol/L) followed by exposure to a green LED (14.34 J cm(-2)). After treatment, the yeasts recovered from the mice were quantified (CFU/mL) and analyzed for the effects of PDT on their adherence to BECs. The data were analyzed using ANOVA, the Tukey test, Kruskal-Wallis test and Student t test.Results. PDT significantly reduced the amount of yeast present in the lesions by 0.73 log(10) (P = .018) and reduced C. albicans adherence to BECs by 35% without damaging adjacent tissues (P = .045).Conclusions. Photodynamic therapy exhibited antifungal effects against C. albicans biofilms formed in vivo and reduced the capacity of C. albicans to adhere to BECs in vitro.
