    Abstract
    Objective: The goal of this study was to assess the efficacy of hydrogen peroxide cleaner disinfectant wipes in reducing the presence of bacteria, specifically Escherichia coli and Methicillin-resistant Staphylococcus aureus (MRSA), opportunistic pathogens, on surfaces in dental offices. Methods: Twelve locations in three different dental offices were tested before, and after the use of the hydrogen peroxide wipes. The colony forming units cm2 were calculated to determine the capacity of the bacterial wipes to reduce bacteria on high touch fomites. Bacterial samples underwent biochemical analyses to determine the presence of heterotrophic bacteria, coliform bacteria, E. coli, and MRSA. Results: Coliform/E. coli were especially prevalent on the dentist’s chair and bathroom doorknob (5.50E+03 CFU/100cm²/1.47E+03 MPN/100cm²). MRSA was detected on the receptionist counter and computer mouse. The amount of heterotrophic bacteria, coliform bacteria, as well as E. coli decreased after the use of the hydrogen peroxide disinfecting wipes. Conclusions: Coliform bacteria, E. coli and MRSA were detected on high touch areas within dental offices. The use of hydrogen peroxide disinfecting wipes can significantly decrease the occurrence of potentially pathogenic bacteria on fomites.
