Post removal techniques used in nonsurgical endodontic retreatment

Removal of posts from root canals is often a tedious and difficult procedure. Factors such as type of post, cement used, interradicular relation of post to canal walls and accessibility of post affects the eventual success. It is necessary, therefore, for the clinician to evaluate his or her ability to remove posts when contemplating retreating endodontic cases. This paper discusses and evaluates a new technique and instruments used to facilitate post removal in nonsurgical endodontics.
