An 8-year-old has a fracture with pulpal exposure of tooth #9 (immature root). What should the dentist do?
Show answer and explanation
Correct answer: A. Apexogenesis
- A. CORRECT. In a vital immature tooth, apexogenesis (vital pulp therapy) preserves pulp vitality so the root can continue to develop.
- B. INCORRECT. Apexification is for a non-vital immature tooth, inducing a barrier.
- C. INCORRECT. Pulpectomy sacrifices vital pulp and halts root growth.
- D. INCORRECT. Extraction is not indicated for a restorable vital tooth.
