NS-22 Critical Review of Endodontic Treatment Outcomes

4 (3 votes)

CE Credit: 0

Program Overview:

The recent emphasis on evidence-based endodontics and reports on the favorable outcomes of implants have focused attention on long-term outcomes of endodontic treatment. Accurate outcomes assessment is important for communication with patients to inform treatment decisions by frankly measuring benefits and risks, but also for validation of the theoretical foundation of endodontics, for guiding research efforts and for supporting the economic viability of practices and, perhaps, our specialty in general. Nevertheless, outcomes assessment may be biased, reflecting outcomes that may not represent actual reality. This session will review endodontic treatment outcomes from a critical perspective. The current best evidence for endodontic treatment outcomes will be reviewed and critically appraised to highlight its strengths and weaknesses. Alternative approaches to outcome assessment will then be outlined to suggest how our specialty might move forward towards better evidence.

At the conclusion, participants should be able to:

  •  Define specific endodontic treatment outcomes based on the current best evidence.
  •  Identify strengths and weaknesses of current endodontic outcomes assessment.
  •  Recognize alternative approaches to endodontic outcomes assessment and discuss actual endodontic outcomes.

Gary B. Carr, D.D.S.

Dr. Gary B. Carr received his AB degree from Cornell University, his dental degree from SUNYAB, and his endodontic certificate from University of Illinois. He spent 4 years in military service in both enlisted and officer ranks, and practiced 3 years of general dentistry before obtaining his specialty training. He has authored chapters in Pathways of the Pulp on both Endodontic Retreatment and Endodontic Surgery (with Scott Bentkover). He has also authored several chapters in Castellucci’s Endodonzia as well as several chapters in Dental Clinics of North America (with Carlos Murgel) over the last decade. He has published a multitude of scientific papers in the Journal of Aesthetic Dentistry, California Dental Association Journal, and Journal of Endodontics. He has published several papers with Bill Costerton on biofilms in endodontics in the JOE and Journal of Microscopy. Dr. Carr is widely considered the “Father of Microscopic Endodontics” and has trained over 1000 clinicians at his research foundation in San Diego (Pacific Endodontic Research Foundation, PERF) in the last 20 years and lectured extensively worldwide. He has trained (with the help of many former PERF grads) most of the Postgraduate Directors of Endodontics in North America. He is the developer of ultrasonic root end surgical techniques as well as dozens of microsurgical instruments and techniques that have basically revolutionized surgical endodontics. He is also the creator of TDO, a digital office software product used by over 1800 endodontists in 30 countries and is now the dominant player in the endodontic software market. His current interests center on biofilm research, measuring endodontic outcomes, and developing a critical assessment of our disease model in endodontics. He lives with his wife and son in Rancho Santa Fe California and maintains a private practice limited to endodontics in Del Mar California.

Shimon Friedman, D.M.D.


Dr. Shimon Friedman is Professor and former Head of Endodontics and Director of the M.Sc. Endodontics Program at the Faculty of Dentistry, University of Toronto, Canada. With over 245 peer-reviewed publications, textbook chapters and research abstracts, Dr. Friedman has acquired extensive experience in conducting and supervising endodontic research projects, culminating in being awarded the AAE’s 2008 Louis I. Grossman Award, as well as the AAE's 2018 I.B. Bender Lifetime Educator Award, for outstanding contributions to endodontic science. Dr. Friedman’s current research focuses on clinical outcomes that form the evidence-base for nonsurgical and surgical endodontic treatment, and on impacts of contracted endodontic cavity designs on nonsurgical treatment efficacy and biomechanical responses of teeth.
