What is the BEST predictor of long-term success for an endodontically treated tooth?
Show answer and explanation
Correct answer: A. Full-coverage (crown) restoration
✓ A) Full-coverage restoration is the best predictor.
Numerous studies consistently show that the RESTORATION placed after RCT is the strongest predictor of tooth survival. Teeth with full-coverage crowns after RCT have significantly higher survival rates than teeth restored with only a filling. This is because RCT-treated teeth are more brittle (loss of moisture, lack of proprioceptive feedback), prone to fracture under occlusal loads, and the crown protects the remaining tooth structure, seals the coronal access, and maintains function. Early coronal seal and full coverage dramatically improve long-term prognosis.
