    Degree of microbial contamination on the surface of a high-speed handpiece after an operating procedure at the dental clinic of the Private University Norbert Wiener, Lima 2019

    The general objective of this research work was to determine the degree of microbiological contamination on the surface of a high-speed handpiece after a surgical procedure in the treatment of patients attending the dental clinic of the Universidad Privada Norbert Wiener. For this purpose, 52 high-speed handpieces were evaluated, and swabs were taken from the handle and head of each handpiece. The samples were placed in various test tubes containing 1 ml of peptone water, which were then transported to the microbiology laboratory for inoculation onto petri dishes to assess the Colony Forming Units (CFU) present in the sample. The results revealed that the microbiological contamination on the head of the handpiece was 182.69 ± 187.47 CFU, while the handle showed 176.92 ± 189.55 CFU. Furthermore, 51.9% of the heads of high-speed handpieces showed microbial contamination, as did 50% of the handles. Additionally, 51.9% of the high-speed handpieces were contaminated with bacteria, while the remaining 48.1% showed no contamination from any microorganisms. The study concluded that the degree of microbiological contamination on the surface of the high-speed handpiece (both head and handle) following a surgical procedure in the dental clinic of the Universidad Privada Norbert Wiener in Lima, 2019, was high.
