Abstract
The present invention provides a portable dental system for use in areas having inadequate sources of power, either for human or for veterinary dentistry. The system provides one or more handpieces, each driven driven by a pressurized nitrogen gas contained in a portable tank. A water reservoir is also provided for medicated water to be applied to the tooth site. The system has two channels to which either a conventional dental handpiece or an abrasive handpiece can be attached. When two abrasive handpieces are attached, two different abrasive materials may be used by the system, one material for cleaning and one material for cutting or abrading.
