Increased taper segmental rotary files

摘要

The present invention comprises an endodontic instrument for preparing root canals in which the cutting surface has an increased taper greater than about 0.06 mm/mm. In the present invention, a plurality of files may be used in which each succeeding file has a minimum diameter substantially equal to the maximum diameter of the preceding file. By using the files of the present invention, a root canal may be prepared using a minimum number of files.
