Abstract:
Endodontic instruments, including files, reamers, and condensers, that lack margins or radial lands. The instruments include at least one edge that does not provide significant tissue-cutting action and at least one cutting edge. The elimination of margins or radial lands reduces the surface area over which the root canal wall is contacted by the working length of the instrument.
