ABSTRACT:
A dental instrument has first stationary and second rotatable tube sections with the rotatable tube section being press fit in the stationary tube section to provide a rotatable and releasable connection between the two tube sections. Stationary and rotatable conduits extend along the sides of the stationary and rotatable tube sections repsectively and are positioned concentric to their respective tube sections at the point of connection between the tubes to provide a rotatable and releasable connection between the stationary and rotatable conduits. A first manually operated valve varies the suction force through the stationary and rotatable tube sections. A second manually operated valve selectively supplies fluid under pressure from first and second fluid supply ducts through the stationary and rotatable conduits to produce a cleaning spray from the rotatable conduit. The pressure spray end of the rotatable conduit and the suction end of the rotatable tube section are provided with a beveled surface to facilitate positioning of the end of the dental instrument close to the work surface. The dental instrument is constructed of plastic and may be disposed of after each use rather than requiring sterilization of the instrument after each use.
