Abstract
Air-abrasive equipment is provided for prophylaxis or tooth cleaning purposes. Provision is made for directing not only the air-abrasive stream or jet but also for directing a stream of warmed water, preferably in the form of a curtain surrounding the air-abrasive stream and serving to enhance the cleaning action and also to entrain the abrasive particles so that they may readily be withdrawn or removed through a liquid suction system.
