Abstract
A method and apparatus for cleaning and sterilizing all parts of a dental apparatus head exposed to contamination in a practical and economical way includes a cleaning chamber, which may be either a separate unit or an integral part of an apparatus head which receives dental instruments connected by hoses to the head. In one embodiment, the chambers are formed within the head and is closed by a flexible cover so that a cleaning fluid can be introduced into the chamber to clean the exterior surfaces and then disinfectants can be sprayed on the exterior surfaces and pass through internal conduits of the hoses and instruments. In another embodiment, the chamber is separate and receives the entire apparatus head and/or support brackets and is closable so that the head and/or support brackets can be thoroughly cleaned on the external surfaces and then subsequently disinfected with the internal surfaces being disinfected.
