摘要
A method of producing an endodontic file that involves grinding in a plane substantially parallel to the longitudinal axis of a rotating dental instrument blank. By grinding the dental instrument blank in this manner, the torsional strength of the resulting endodontic file is not eroded during its production, thereby providing a file that is less susceptible to breakage during its use.
