title: The use of tungsten carbide needle holders to remove intracanal objects.
abstract: The removal of metallic filling materials and posts is necessary before endodontic retreatment. Retreatment in such cases can require considerable time and effort. This article presents a technique to facilitate the removal of metallic obstructions from root canals using tungsten carbide needle holders. Clinical cases demonstrate the effectiveness of this technique.
