ABSTRACT:
A transducer activated subgingival tool for contacting subgingival tooth surfaces and directing a fluid adjacent to said surfaces, wherein the tool has an activated tip having a fluid inlet end, a subgingival outlet end, a step in the surface of the outer wall of said tip between said inlet end and said subgingival outlet end, and a fluid passageway wall internal to the tip. The passageway wall is formed in the inlet end generally along the longitudinal center axis of the inlet end of the tip. In a preferred embodiment of the invention, the step intersects the passageway wall at the orifice edge.
