Abstract

Endodontic treatment success relies on the proper cleaning and shaping of the root canal. All the surface of the root canal must be prepared to remove the infected dentin. Many file are available with various advantages and limitations for every system to prepare the root canal. This article highlights about the metallurgy of the file that is used to manufacture the file.
