ABSTRACT:
An air-driven dental scaler is disclosed having water transport means associated with the tool assembly for delivering water to a scaling type work tool. The water transport means comprises a tube disposed within a hollow connector body and extending between a water plenum at one end of the connector body to the other end of the connector body, whereat the scaling type work tool is attached. The water transport tube has an internal diameter of greater than 0.010 inch and a surface roughness smoother than 25 micro-inches to minimize clogging of the tube by mineral deposits or sediment. The independent fluid path permits the use of hard, martensitic stainless steels for the work tool and softer, corrosion-resisting austenitic stainless steels for the water transport tube. The water transport means delivers a controlled quantity of water to the work tool and the water is atomized by the vibratory movement of the tool.
