The job of an endodontic file is to remove diseased pulp tissue from the canal, shave dentine from the canal space and shape the canal so that it can be filled properly.
Endo files come in a variety of different designs and sizes. The most widely used files in endodontics are NiTi (nickel-titanium) files, K-files (Kerr files) and H-files (Hedstrom files).
More information on the specific roles of each file can be found in our Endodontic Files Guide, along with detail on file tapers, sizes, colour codes and features.
