| Summary: | Dental handpieces used in clinical practice are a very high focus for
the accumulation of potentially infectious microorganisms and for cross-contamination to
exist. Ultraviolet C light is a type of electromagnetic radiation produced artificially, which
has been used successfully during the last few years as a germicidal agent, demonstrating
more and more its effectiveness in equipment used in different areas of health, especially
in dental practice. This experimental research project seeks to demonstrate the efficacy of
the portable box with ultraviolet C light as an aerobic bactericidal agent in handpieces. For
this purpose, 96 samples were taken by the direct swabbing method from the contaminated
handpieces after patient care and then ultraviolet C light was applied in the portable box to
the handpieces for 10 minutes following the indications of the manufacturer's technical
data sheet; and subsequent samples were taken by the direct swabbing method. Then the
aerobic bacterial growth before and after exposure with ultraviolet C light was determined
by the colony count method in plate and the absorbance quantity measurement was
determined in the spectrophotometer. Materials and methods: This experimental study
was carried out with 96 handpieces from the adult clinical practice of the Antonio Nariño
University, Neiva campus. |
