Contemporary Endodontic Treatment Outcomes Explained

The rapid increase in outcome studies, use of various outcome terminologies, and inconsistent results, have all combined to obscure the actual outcomes of contemporary endodontic treatment modalities. This is confusing to clinicians, and it may act to skew treatment decisions.

To navigate the existing ambiguity, it is necessary to consider the main purposes and stakeholders of treatment outcomes, and the explicit outcome goals that may be set by informed individual patients. This perspective forms the basis for structured methodological appraisal of all published studies, to select those that comprise the CURRENT BEST EVIDENCE for each treatment modality. The longer-term, pertinent outcomes reported in the current best evidence studies are then summarized and effectively communicated to inform treatment decisions.

Following the above strategy, this lecture will highlight the outcomes of endodontic treatment in regard to periapical health, symptom-free function, and survival/retention, based on the current best evidence. Outcome predictors supported by the current best evidence may also be listed.

Major topics to be addressed:
Periapical health, symptom-free function and survival/retention after Initial Treatment, Orthograde Retreatment, and Apical Microsurgery.
Learning Objectives:
  1. List the outcome studies that comprise the Current Best Evidence for nonsurgical and surgical endodontic treatment
  2. Based on the Current Best Evidence, summarize the chances of treated teeth to be healthy, symptom-free, and retained long-term after nonsurgical and surgical endodontic treatment
  3. Based on the Current Best Evidence, discuss the healing outcome predictors after nonsurgical and surgical endodontic treatment
