An 8-year-old breaks a permanent central incisor with pulp exposure. What is the best treatment?
Show answer and explanation
Correct answer: C. Direct pulp cap with MTA
- A. Extraction is not indicated for a restorable permanent tooth with vital pulp.
- B. Indirect pulp cap is for teeth WITHOUT pulp exposure (near-exposure from deep caries).
- C. For an immature permanent tooth with vital pulp exposure from recent trauma, direct pulp cap with MTA (or biodentine) is the treatment of choice. MTA promotes dentinal bridge formation, has superior biocompatibility, and supports continued root development (apexogenesis). Best outcomes with exposure <24–48 hours old.
- D. Pulpectomy/pulpotomy is needed if the pulp is irreversibly inflamed or necrotic; a recent vital exposure in an immature tooth should first attempt MTA pulp capping.
