What is the purpose of confirmatory radiographs in endodontic treatment documentation?

• A. To evaluate occlusion only
• B. To measure tooth color
• C. To verify file length and fill placement
• D. To determine patient's insurance coverage

Answer: (C)

Confirmatory radiographs in endodontic treatment documentation are used to verify that the instruments and filling materials are positioned at the correct length inside the root canal. After establishing working length, a radiograph shows whether the canal was prepared to the intended depth and whether the master cone or obturation reaches the appropriate length without underfilling or overfilling beyond the apex. This radiographic check helps ensure the quality and completeness of both canal preparation and obturation, and it provides a verifiable, permanent record of the treatment. It’s not used to assess occlusion, tooth color, or insurance coverage; those issues are addressed through other clinical assessments or administrative processes.
