An X-ray of tooth #19 shows a completed root canal treatment; the tooth has dilacerated roots, and gutta-percha has been extruded beyond the apex of one root. What is the visible PROBLEM shown on this X-ray?
Show answer and explanation
Correct answer: B. Extrusion of root canal filling material beyond the apex
While the dilacerated root shape is a notable anatomic feature mentioned in the case, it is simply a description of the tooth's anatomy — not itself the 'problem' being asked about. The specific procedural problem visible on this film is the extrusion (overfill) of gutta-percha root canal filling material beyond the apical foramen.
