Abstract
Abstract A compact portable and essentially unitized dental apparatus having a stable support base and a top carrying handle enables the visiting dentist to perform all necessary dental services at nursing homes, homes of invalids, hospital emergency rooms and in the field as with military or missionary personnel. A compressor-compressor motor unit forms the body on which other components of the apparatus are mounted. Electrical or gasoline engine compressor operation is feasible. The apparatus will operate high and low speed dental drills, a three-way syringe, and high volume suction device. Individual components are standard commerical items.
