ABSTRACT:
A single handpiece that can be used in multiple dental treatments is provided. The handpiece comprises a housing having a coil for producing an electromagnetic or electrostrictive field in the housing, and a number of inserts that react with the electromagnetic or electrostrictive field and can be used with the housing to complete the handpiece. A switching system used with the handpiece, which electrically recognizes the particular insert used with the housing provide for automatically controlling circuitry that determines which of a number of materials and medicaments are to be delivered to the handpiece for use with a particular insert. Circuitry which provides better control of the ultrasonic insert in the handpiece is also provided.
