Abstract: A dental syringe having an angulated nozzle projecting from one end of a housing. Two coaxial valve operating buttons project from the other end of the housing and are axially operable to supply water, air or both to the nozzle. The operating buttons are connected to coaxial valves within the housing, one of the buttons and its valve being rotatable to change the angular position of the nozzle.

Abstract: A dental handpiece control in which a single housing for controlling the flow of air and water to a dental handpiece is combined with a foot pedal. In the housing is a pressure regulator directly operated by the foot pedal and a water valve controlled by air from the pressure regulator. A switching valve operated by push buttons adjacent the foot pedal controls the flow of air to the water valve, the operation of the push buttons determining whether the handpiece is operated on an air mode or an air/water mode. The water valve is designed to eliminate drip when the instrument is shut off by drawing water from the handpiece toward the control unit upon relief of air pressure from the water valve.
