Clorhexidina al 0,12% y ácido acético al 5% como desinfectantes de cepillos dentales. Rev Eug Esp [online]. 2020, vol.14, n.1, pp.53-64. ISSN 2661-6742.  https://doi.org/10.37135/ee.04.08.08.

The present study was of a comparative observational type. 40 OralDent toothbrushes were analyzed for this reserach, which were used for a month by the members of the “Simón Bolívar” Taxi Cab Company in the city of Riobamba, Ecuador. It aimed to compare the efficacy of 5% acetic acid and 0.12% chlorhexidine as disinfectants. The microbiological analysis showed the presence of microorganisms in the toothbrushes used by the individuals who voluntarily gave them up for the study, for exmaple: C. albicans in a greater proportion, followed by S. viridans, S. epidermidis and S. mutans, A. tubingensis, K. pneumoniae, E. coli, E. faecalis, P. vulgaris. Once the disinfection process with 0.12% chlorhexidine was generated in the samples with microorganism concentrations of 100,000 CFU / mL, there was a decrease to values less than 20,000 CFU / mL or its complete elimination. 5% acetic acid achieved asepsis in 100% of toothbrushes regardless of the age or gender of the individual who used it.
