Disinfection of Surfaces and Equipment

Chemical disinfection of surfaces and instruments is an important aspect of infection control as routinely practised in dental units and elsewhere. The timing and method of chemical disinfection, the factors affecting the efficacy of germicides and the hazards posed by their use are important considerations in selecting disinfectants. The terminology used for such chemicals is often confusing, and many of the common synonyms (such as biocide, microbiocide, germicide and disinfectant) imply a broad spectrum of efficacy against a range of microbial pathogens. However, a given product may actually carry claims for activity against only one class of microorganisms, usually vegetative bacteria. Therefore, the user is urged to closely examine a product’s label claims before purchase to assess its potential for surface disinfection or decontamination.
