Question

During root canal treatment, a file separates in the apical third of a curved canal. The tooth is strategically important and there is no indication for immediate extraction. Which is the most appropriate management approach?

Accepted Answer

Assess retrieval risk; attempt bypass or conservative retrieval, then seal coronal to the fragment or consider surgery if needed

Answer

Extract the tooth because a retained intracanal fragment inevitably causes endodontic failure

Answer

Irrigate repeatedly with sodium hypochlorite until the metal fragment dissolves enough for removal

Answer

Enlarge the canal aggressively until the fragment is removed, regardless of remaining root dentine

Answer

Push the fragment through the apical foramen before completing canal preparation and obturation
