Abstract:
A method for abrading root canal surfaces, comprising:identifying an operative length of a root canal, obtaining an endodontic instrument comprising a file adapted to remove and clean pulp material from a root canal during an endodontic procedure in an abrasive action, the file having a proximal end and a distal insertion end, and a handle having a top end and a bottom end and a diameter that is greater than the diameter of the proximal end of the file, the proximal end of the file being substantially concentric with the handle and extending from the bottom end of the handle; obtaining an endodontic handpiece head adapted to receive the handle and releasably hold the handle while rotating the endodontic instrument; inserting the handle of the endodontic instrument into the endodontic handpiece head; adjusting the position of the handle within the endodontic handpiece head such that the instrument has a desired working length relative to the endodontic handpiece head; securing the handle within the endodontic handpiece head through pressure applied by the endodontic handpiece head against the handle; inserting the file into the root canal; and urging the file against surfaces in the root canal as the instrument is operatively moved by the endodontic handpiece head.
