1) Tooth survival as it relates to patient-centered, disease-centered, and process-centered outcome parameters.
2) Retention of teeth with “guarded” or “poor” prognosis.
3) Failure of technically superior endodontic treatment.

Understand why patient-related and other factors outside of the clinician’s control may have the greatest impact on tooth survival.
