Objective: To evaluate in vitro the effectiveness of fungal formulations (edible mushrooms and Penicillium crustosum Thom fungus isolated from molded coffee capsule) in tooth whitening, initially using coffee beverage whitening as a reference, followed by the application of these block formulations dental cattle. Methodology: The evaluation of the whitening effectiveness was given by comparing the results obtained with conventional methods, evaluating the color after the treatments (ΔL *, Δa *, Δb * and ΔE), besides the dental structure evaluation, using roughness variation (ΔRa ), surface transverse microhardness (CSMH) and scanning electron microscopy (SEM) images as a parameter. Statistical analysis was performed using one-way analysis of variance (ANOVA) and Tukey test for microhardness and roughness results (a = 0.05). The color data did not meet the assumptions of a parametric analysis and was analyzed by the non-parametric Wilcoxon test in the analyzes between the final and initial times (a = 0.05). The color data did not meet the assumptions of a parametric analysis and were analyzed by the nonparametric Wilcoxon in the analyzes between the end times and initial (a = 0.05). Results: The previous results of the effectiveness of specific enzymes in the discoloration of coffee drink and in the bleaching of bovine dental blocks showed that both mushrooms and the fermentation extract with the filamentous fungus were able to clear the dental blocks, with ΔE values of approximately ¾ of the value obtained with conventional bleaches. Conclusion: It is concluded that the use of fungi as an alternative method in tooth whitening is promising, since it consists of a natural method and may cause fewer adverse reactions when compared with conventional methods.
