Question

  1. What is the clinical effectiveness of root-canal re-treatment in permanent teeth after failed root canal treatment compared to initial root canal treatment alone (i.e. no treatment) or tooth extraction?
  2. What is the clinical effectiveness of apicoectomy with or without apical curettage in permanent teeth after failed root canal treatment compared to initial root canal treatment alone (i.e. no treatment) or tooth extraction?
  3. What is the clinical effectiveness of retrofilling in permanent teeth after failed root canal treatment compared to initial root canal treatment alone (i.e. no treatment) or tooth extraction?
  4. What is the cost-effectiveness of root-canal re-treatment in permanent teeth after failed root canal treatment compared to initial root canal treatment alone (i.e. no treatment) or tooth extraction?
  5. What is the cost-effectiveness of apicoectomy with or without apical curettage in permanent teeth after failed root canal treatment compared to initial root canal treatment alone (i.e. no treatment) or tooth extraction?
  6. What is the cost-effectiveness of retrofilling in permanent teeth after failed root canal treatment compared to initial root canal treatment alone (i.e. no treatment) or tooth extraction?
  7. What are the evidence-based guidelines regarding the use of root canal re-treatment, apicoectomy with or without apical curettage, and retrofilling in permanent teeth?

Key Message

No evidence was identified regarding the clinical and cost effectiveness of endodontic interventions following a failed root canal treatment. No evidence-based guidelines for endodontic re-treatment were identified.
