ABSTRACT:
A nozzle for use with a dental tool having a hand-piece comprising first and second fluid conduits for delivering first and second fluids to a discharge end of the hand-piece. The nozzle is releasably engageable with the discharge end of the hand-piece and comprises an inner tube and an outer tube each having an intake end and a discharge end. The tubes define first and second fluid passages having coaxial intake ports for fluid communication with the first and second fluid conduits and coaxial discharge ports for pressurized delivery of the first and second fluids to the teeth of the patient. The intake end of the inner tube extends axially from the intake end of the outer tube and is connected to the first conduit when the nozzle is engaged with the hand-piece so that fluid discharged from the first conduit flows through the first passage. The intake end of the outer tube is shaped so that the intake port of the second fluid passage avoids seating against a portion of the hand-piece thereby to maintain a passageway between the intake port of the second fluid passage and the portion of the hand-piece so that fluid flowing through the second conduit flows through the fluid passageway to the second passage.
