Abstract (en)
[origin: WO02062251A2] A series of multi-tapered files is disclosed for endodontic use. The files comprise at least two sections, a first portion adjacent the tip of the file and a second portion adjacent the shank. The two portions have different tapers. The files are provided in sets of at least four with the tapers of the first portions of all of the files decreasing incrementally from the first to the last file of the set. In some of the sets, the tapers of the second portions are the same from file to file, being fixed at one of two selected tapers. In other sets, the tapers of the second portions increase from file to file as the tapers of the first portions decrease.
