Abstract
A set of endodontic instrument adapted to remove material from walls of a root canal having a working portion with a relatively short working length. A substantially untapered nonworking portion of the instrument shaft with substantially parallel sidewalls and a diameter substantially the same as the diameter of the proximal end of the working portion extends from adjacent a proximal end of the working portion to the proximal end of the shaft. The working portions of the set of instruments have relatively small, slowly progressing taper rates.
