Abstract
A dental instrument includes a pneumatic pressure intensifier that supplies a handpiece having an orifice to generate a high velocity liquid jet. A pneumatic system includes valves to supply the pressure intensifier and control the output to the handpiece. A jet forming assembly includes an orifice mount in the handpiece, and a guide tube assembly secured to the orifice mount. The guide tube assembly is variably positioned to select the minimum distance from the jet orifice to the tissue target, so that the jet force may be controlled.
