Abstract
A blank for use in producing an endodontic instrument using a grinding technique includes a cylindrical portion, and a generally conical portion which is to be machined by the grinding technique to form the active part of the endodontic instrument. The generally conical portion of the blank approximates, and is slightly larger than the envelope of the final shape given to the active part of the endodontic instrument after machining. A method is also provided for producing an endodontic instrument having at least one helical cutting edge using the blank.
