Introduction: Tooth brushing is an important measure in promoting oral health. However, the brush suffers the deposition and proliferation of microorganisms in its bristles during its use. In addition, a correlation has been demonstrated between the microbial load found on toothbrushes and the dental status of patients. Aim: To evaluate the biofilm formation on toothbrushes by mutans group streptococci and Candida spp. isolated from the oral cavity of students at the State University of Goiás. Methodology: The methodology employed in this study allowed the collection, isolation, and presumptive morphological identification of oral microorganisms, and allowed the evaluation of biofilm formation by both microorganisms in sterile toothbrushes. Results: All microbial isolates were able to form biofilms under the tested conditions, with microbial cell counts adhered to the biofilm ranging from 6.75 to 11.00 log10 cfu·mL-1 for mutans group streptococci, and 4.94 to 5.79 log10 cfu·mL-1 for Candida spp. Mutans group streptococci and Candida spp. were isolated from 92.31% of brushes used in the collection of samples from the oral cavity of the volunteers. Conclusion: All microorganisms isolated were able to form biofilm on toothbrushes, which corroborates the importance of care with decontamination of toothbrushes in promoting oral health.
