A 5 mm file segment separates in a canal during root canal treatment. What is the MOST appropriate next step?

  1. Continue the root canal as if nothing happened
  2. Immediately attempt ultrasonic retrieval
  3. Extract the tooth immediately
  4. Inform the patient and refer to an endodontist
Show answer and explanation

Correct answer: D. Inform the patient and refer to an endodontist

  • A. Incorrect. Continuing without disclosure violates patient rights and ethics.
  • B. Incorrect. Ultrasonic retrieval should be performed by an endodontist in a controlled setting — not necessarily an immediate general dentist attempt.
  • C. Incorrect. Extraction is not automatically indicated — separated instruments with proper management often have favorable prognoses.
  • D. Correct. First obligation: INFORM THE PATIENT (veracity/informed consent). Then REFER TO AN ENDODONTIST for evaluation. Options include bypass, retrieval with ultrasonics, or intentional retention with monitoring.
