A post-RCT tooth #8 has a poor-quality composite veneer. What is the most appropriate definitive restoration?
Show answer and explanation
Correct answer: A. Core build-up followed by a crown
- A. ✅ Correct. The standard of care for a non-vital endodontically treated tooth with a failed restoration: (1) CORE BUILD-UP to replace missing tooth structure and create a proper foundation, then (2) CROWN for full coverage protection and esthetics.
- B. ❌ A crown without core build-up may be insufficient if existing tooth structure cannot adequately retain the crown.
- C. ❌ Repeating a composite veneer alone does not provide adequate long-term protection for a non-vital tooth.
- D. ❌ Indirect veneer requires adequate tooth structure and enamel — may not be suitable for a post-RCT tooth with failed restoration.
