Disinfection of the
Root Canal System

Matthias Zehnder, PROF. DR. MED. DENT., PhD
Prof. Matthias Zehnder graduated from the University of Bern School of Dental Medicine in Switzerland in 1994, where he received his doctoral degree in dentistry in 1996. Subsequently, he worked in private practice and part time as a postdoctoral research fellow at the Department of Oral Cell Biology of the same dental school. Between 1998 and 1999, he was employed at the Department of Oral Biology and Periodontology of Boston University Henry M. Goldman School of Dental Medicine, Massachusetts, U.S. He then pursued specialist training in endodontics at Columbia University in the City of New York, U.S., from which he graduated in 2001. In addition, Zehnder completed his PhD at Turku University in Finland in 2005 and received the title of "docent" from the University of Zurich in Switzerland in 2007. Currently, he is the tenured Head of the Division of Endodontology at the Clinic of Preventive Dentistry, Periodontology and Cariology at the university.
Course benefits/Highlights

Most clinicians do not read the dental literature, which is a petty and makes them easy targets for sales people. This course will focus on one of the core aspects of endodontic treatment, which is the disinfection of the root canal system. What do we know and why do we know it? An easy approach to read clinical papers will be presented, and 3 articles will be discussed that influenced our knowledge and clinical approach. Based on this background, clinically relevant microbiology will be discussed, followed by diagnostics of painful tooth conditions, emergency treatments, chemomechanical root canal disinfection, and revascularization.

At the end of the course you should be able to:

- Understand the core concepts of clinical trials.
- Become familiar with the nature of root canal infections.
- Be able to diagnose and treat endodontic emergencies.
- Learn effective strategies for root canal disinfection.
-Evaluate the core concepts and current challenges of regenerative endodontics.

Synopsis: Clinical trials evolve around a focused question. PICO stands for population-intervention-control-outcome. Only randomized trials can show causality, yet even these studies can have limited clinical meaning, because root canal treatments are complex microsurgical interventions with many redundant steps. A classic example of how people drew the wrong conclusions from clinical studies is the tale of the Enterococcus in root canal infections, which will be discussed. Based on the truly relevant microbiology of root canal infections, approaches for diagnostics, emergency treatments, root canal disinfection in general, and revascularization treatments will be presented.
