ABSTRACT:
A dental syringe tip for use with a hand-piece of an air-water syringe to deliver air and water to a mouth of patient. The syringe has air and water conduits for delivering air and water to a discharge end of the hand-piece. The dental syringe tip includes a single unitary tube releasably engageable with the discharge end of the hand-piece. The tube has a fluid passageway extending from an intake port at an intake end of the tube for fluid communication with the air and water conduits of the hand-piece. In addition, the tube has a discharge port at a discharge end of the tube for delivering at least one of the air and water through the passageway to the mouth of the patient. The intake end of the tube is shaped and constructed to enable air and water flow through the air and water conduits when at least a portion of the intake end of the tube engages the discharge end of the hand-piece. The intake end of the tube at least partially defines a chamber when the portion of the intake end of the tube engages the discharge end of the hand-piece for transporting air from the air conduit of the hand-piece to the intake port of the tube and for transporting water from the water conduit of the hand-piece to the intake port.
