ABSTRACT:
A hand-holdable apparatus useful for abrading a surface is provided. The invention is particularly useful for dental applications using a stream of abrasive particles suspended in a gas stream to abrade the surface of a tooth. The apparatus of the invention may be modified to easily minimize “bleed down” of the gas/abrasive stream using a pinch valve and to remove worn flexible conduits for routine maintenance and autoclaving of the apparatus. The apparatus of the invention also provides a novel pick-up assembly for delivery of abrasive particles.
