ABSTRACT:
A root canal is sequentially cleaned in sections from the crown to the apex. An opening is first formed into the tooth to provide access into the root canal. The opening is preferably rectified to remove obstructions from fully accessing the anatomical root canal. The pulp material is then sequentially removed from the portion of the root canal above the apical portion of the root canal with a first set of instruments and then from the apical portion with a second set of instruments. Cleaning of the pulp material from the root canal also shapes the root canal to ease filling of the root canal with a filling material. Each instrument comprises a handle connected to a file. Each file has an abrading portion and terminates at a tip. The files used to clean the portion of the root canal above the apical portion have properties which enable the abrading portion of the file to conform to the configuration of the root canal while simultaneously moving the file in a cleaning motion.
