The removal of gutta-percha and root canal sealers from root canals.

The removal of gutta-percha from root-filled teeth is required for re-treatment of failed endodontic treatment and to prepare a space for placement of a post. Complete removal of filling material and sealer is a requirement for success. A review was undertaken of the current literature on methods of gutta-percha and sealer removal. Clinical recommendations based on current evidence are included. A combination of methods may be required to remove filling materials effectively.
