Abstract: Foreign objects in the pulp chamber or root canal are not unusual findings in patients undergoing root canal treatment in which canals have been left open for drainage. These can be easily removed with care not to push the objects apically, but once the object has been pushed to periapical area, the case becomes very difficult especially when the root end is immature. The presence of a foreign body increases the difficulty of eliminating infection by intracanal treatment alone. The options left are either periapical surgery or intentional re-plantation to remove the foreign objects in addition to canal filling.
