ABSTRACT:
An air driven turbine supporting a burr is pivotably mounted at the extremity of an arm, which arm is pivotably attached to the handle of a dental hand piece. Conduits extend through the handle and the arm to the turbine and provide a flow of air to and from the turbine and a flow of fluid directed into proximity of the cutting surfaces of the burr. Sealed moveable junctions at each end of the arm maintain integrity of the air and fluid flows while accommodating articulation of the hand piece.
