Disinfection and sterilisation: the duties and responsibilities of dentists and dental hygienists.

Disinfection and sterilisation have received a considerable amount of attention due to the spread of AIDS in the past few years. There appears to be a low risk of occupational transmission of HIV, but this is not the case with other transmissible diseases. There are about 40 infection hazards for the patient and dental personnel in the dental surgery. Disinfection and cleaning are important in disease containment and cross-infection control, and all members of the dental team must bear responsibility for this. Disinfection of hands, surfaces, instruments, impression materials, radiographic units and suction systems are discussed. In addition, sterilisation and hygiene management of the reception area are considered. The duties and responsibilities of the dental team are emphasised.
