ABSTRACT:
This invention relates to a dental drill which includes a built in fluid conveying tube to supply a fluid in the form of water which becomes a mist when it strikes a rotating burr.The drill also includes a built in suction apparatus which can aspirate fluid and air from the area around the burr during the course of the drilling operation. The burr is usually driven by means of an air turbine, but the aspirated fluid-air mixture can be made to pass transversely across the turbine becoming the driving force for rotating the burr.
