Abstract

The invention disclosed herein provides a shield for use in operating dental hand tools outside of a patient's mouth while preventing escape of any matter ejected from the hand tool into the surrounding vicinity, thereby eliminating or substantially reducing the risk that the ejected matter may otherwise contaminate nearby people or equipment. The shield has an enclosure within which the end of a dental hand tool is placed and operated. The shield is removably coupled to a waste line or the like typically already present in a dental office, such as a high volume suction line, a saliva ejector suction line or a cuspidor. The shield contains therein any matter ejected from the hand tool during operation thereof, and such matter is carried away by the waste line. When the enclosure is coupled to the waste line, escape of the matter ejected from the end of the hand tool is substantially prevented except through the waste line. The shield is preferably disposable.
