[Infection control in dentistry. II.: Disinfection od dental handpieces]

The effectiveness of three different kind of sterilization or disinfection procedures was investigated in case of contaminated turbine handpieces. The results demonstrated that formaldehyde, isopropyl-alcohol and ethylenoxid are equally effective to disinfect or sterilize handpieces. The isopropyl-alcohol solving in pure ethyl-alcohol is one of the material which complies most of the requirements, as described by the authors.
