A patient taking bisphosphonates needs management of a non-restorable tooth. To minimize MRONJ risk, the preferred approach (versus extraction) is:

  1. Endodontic treatment with coronectomy (retain the root, reduce the crown)
  2. Immediate surgical extraction
  3. No treatment at all
  4. Aggressive alveoloplasty
Show answer and explanation

Correct answer: A. Endodontic treatment with coronectomy (retain the root, reduce the crown)

  • A. Correct. To avoid the bone trauma of extraction, root canal treatment followed by decoronation/coronectomy (leaving the root and modifying the restoration/retainer) reduces MRONJ risk.
  • B. Surgical extraction is the main MRONJ trigger and is avoided when possible.
  • C. Doing nothing leaves infection/pain unmanaged.
  • D. Aggressive bone surgery increases MRONJ risk.
