Abstract:
High concentrations (80-90%) of ethanol seem to be best for use in the dental office. A mixture of 80% ethanol and 5% isopropanol was shown to inactivate HIV, hepatitis B and C viruses within 20 seconds. Compared with alternative antiviral disinfectants, such a mixture is non allergenic and minimally toxic for the dental team. It is suitable for spraying or for the spray-wipe-spray technique as an important cross-infection control measure in dentistry.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
