ABSTRACT OF DISCLOSURE This disclosure is directed to a dental syringe and a disposable syringe tip for use therewith, and more particularly to an improved syringe tip constructed to minimize the entrain- ment of air by the material being extruded and to provide a dentist with a maximum of visibility during use. The syringe tip includes a cylindrical body portion to define a reservoir that is provided with a conically shaped, closed front end and a full opening at the other end, which is adapted to be sealed by a displaceable piston. The closed front end is provided with an internal frusto-conical chamber disposed in communication with an angularly offset discharge nozzle having its passageway at the inner end thereof disposed contiguous to the blunt end of the internally disposed frusto-conical chamber; and the disposable piston having a frusto-conical end portion to complement the shape of the internal front end of the syringe tip to enhance the complete evacuation of the material disposed within the syringe tip without the entrainment of any air.
