Abstract
Abstract This invention relates to a dental syringe for coupling between a water outlet and shower head. An adapter having a main passageway therein is furnished for coupling between the water outlet and the shower head for passing water therebetween. A main diverter valve is coaxially within a main passageway through the adapter for coupling the water under pressure to the shower head when the main diverter valve is in a first position, and diverting the water under pressure to the dental syringe when the diverter valve is in a second position. The dental syringe is coupled to a flexible conduit which is in turn coupled to the shower head adapter. The dental syringe includes a secondary control valve axially rotatable within a syringe passageway for controlling the volume of water expelled from the outlet port of the syringe. A combination holder and shield is coupled to the flexible conduit for storing the dental syringe therein.
