CE Credits: 1.5

Course Description: The outcome of a nonsurgical endodontic therapy has barely changed over the last five decades, particularly in nonvital cases. This is a major concern when we consider all the technological improvements such as microscopes and NiTi files. New outcome studies have attributed this to our limitation to achieve effective and predictable disinfection of the root canal systems. In order to overcome this critical limitation, new irrigants, techniques and devices have been incorporated to endodontic therapy in the last decade. Our main challenge remains the apical third and its anatomical complexities. Understanding the physical limitations and fluid dynamics of a closed-canal system, with complex anatomy, is extremely important if we want to thoroughly disinfect the entire system and achieve our ultimate goal, healing of apical periodontitis. This presentation will discuss and illustrate all current techniques, activation systems and solutions to enhance disinfection and subsequently improve endodontic outcome.  

At the conclusion, participants should be able to:

  • Evaluate the physical challenges of the irrigation into closed canal systems.
  • Discuss different irrigation and activation protocols.
  • Demonstrate the predictability of effective and tridimensional disinfection of the entire root canal system.

He served since from 2009 to 2013, on faculty at the school while maintaining a private practice limited to endodontics. He received the title of Active Member of the Spanish Association of Endodontics in 2011. He is active in research and has published articles in peer-reviewed journals, being author of chapters in books about Endodontics. He became Assistant Professor of the Department of Endodontics at the University of Washington in 2013 where served as a clinical assistant professor of the department of endodontics and as an endodontist at the Center for Pediatric Dentistry. Actually, he serves as a Board director of the International Association for Dental Traumatology (IADT) and is member of the committee of Research and Case Awards as well as the committee of Education and prevention. He became Sub-Director of the Graduate program in Advanced Endodontics at Universidad Rey Juan Carlos (Madrid-Spain) in 2016 and performs treatments in his private practice, limited to endodontics and dental trauma.
