ABSTRACT:
A syringe tip for use with a dental tool having a hand-piece for delivering air and water to a discharge end of the hand-piece. The syringe tip is releasably engageable with the discharge end of the hand piece and has an intake end and a discharge end. The tip has a fluid passageway defined at least in part by the tube having an intake port adjacent the intake end of the tube for fluid communication with the fluid conduit of the hand-piece and a discharge port adjacent the discharge end of the tube for pressurized delivery of the fluid to the mouth of a patient. The intake end of the tube is shaped to avoid blockage of the fluid conduits by the tube. The tip further comprises a viscous liquid within and occluding the fluid passageway for being discharged from the discharge port into the mouth of the patient when the fluid is delivered to the mouth of the patient via the hand-piece and fluid passageway.
