Question

  1. What is the clinical-effectiveness and prognosis of placing crowns on endodontically treated teeth?
  2. What is the cost-effectiveness of placing crowns on endodontically treated teeth?
  3. What are the evidence-based guidelines for placing crowns on endodontically treated teeth?

Key Message

A total of three systematic reviews and four non-randomized studies were included in this review. The available evidence suggests that the short term survival (2 to 3 years) of root canal treated teeth restored with crowns or direct fillings is comparable. On the long term however, the evidence suggests that root canal treated teeth have better survival rates at 10 and 20 years after treatment.
