An <i>in vitro</i> study comparing root‐end cavities prepared by diamond‐coated and stainless steel ultrasonic retrotips

Abstract

A better quality surface was produced by the prototype diamond-coated retrotips, in less time than the SS retrotips, which in turn caused fewer cracks than previously reported. DC retrotips removed more dentine than SS retrotips and should therefore be used with care to avoid overpreparation or perforation.
