Abstract

The fundamentals of successful endodontic treatment are an awareness of the aetiology of the disease process and an understanding of factors that affect outcome. This paper aims to outline the prognostic factors found in the endodontic outcome literature to facilitate options appraisal and predictable treatment delivery. We will discuss pre-treatment, treatment and post-treatment factors. In summary, the significance of infection control throughout treatment, provision of an adequate coronal seal and appropriate restoration of the root-filled tooth are highlighted.

Key points

  • Knowledge of the aetiology of endodontic disease and the factors affecting the outcome of root canal treatment are the key to decision-making and the provision of predictable treatment.
  • Factors related to the extent of microbial contamination of the root canal space and our management of this have a significant impact on success.
  • Provision of an adequate coronal seal and the appropriate restoration of the tooth are key contributors to long-term success.
