Abstract

A dental apparatus (1) and method, for example an endodontic apparatus and method, is disclosed. The apparatus comprises: a supply of fluid (12); a pump (14) for delivering fluid from the supply (12) under pressure and a handpiece 20 in fluid communication with the pump (14). The handpiece (20) comprises a needle (30), extending from a rearward end proximal to the handpiece to a forward tip distal from the handpiece, a lumen of the needle extending to an opening at the tip to deliver fluid received from the pump to a tooth. The dimensions of the needle and the delivery pressure of the fluid are selected such that the flow of fluid through the needle causes a cloud of inertial cavitation to be formed forward of the needle tip.
