About the Clinical Expert

Dr. Buchanan is a Diplomat of the American Board of Endodontics and a Fellow of the International and American Colleges of Dentists. He is a Visiting Lecturer at the University of California at Los Angeles School of Dentistry.

He has logged over two million air miles lecturing around the world and has performed live demonstrations of his endodontic procedures for annual meetings of the ADA, AAE, AAED, CDA (CA), CDA (IL), as well as for all of the 450  hands-on courses he’s given at his Santa Barbara DELabs Training Academy since 1989.

Dr. Buchanan has 24 US and international patents for dental devices and has been a frequent contributor to Dentistry Today magazine for over 30 years.

Dr. Buchanan enjoys designing and making stained glass, jewelry, and furniture, but 40 years later his greatest thrill remains invading diseased root canal systems at his state-of-the-art practice in Santa Barbara, CA.

Endodontic Treatment in the Age of MIE


The last 30 years have seen the total reinvention of endodontic instrumentation and obturation, yet the irrigation of root canal systems–arguably the most important aspect of RCT–has been given short shift until recently. Fortunately, this is now the most active development arena in the specialty, however, with $80,000 laser and sonic cavitation tools promoted as necessary solutions to this conundrum, clinicians are left to wonder which path to take forward. Concurrently many endodontists have committed to preserve the structural integrity of the teeth they treat through the application of minimally-invasive concepts and procedures. Interesting times, no?

The great news is that instrumentation has never been so simple or so safe, as most canals can be ideally negotiated and shaped with just one or two rotary files. In addition, bioceramic filling materials have reduced the time and technical challenges of 3D obturation of RC systems to the point that most canals can be filled to their apical and lateral extents with single-cone filling methods. For those in the know, irrigation is truly the final frontier.

Dr. Buchanan, through graphical illustrations, CBCT imaging, and HD video footage of live procedures, will explain where and how clinicians can save tooth structure by using efficient MIE principles and how they can optimize the physics and hydrodynamics of endodontic irrigation to achieve cleaning results that empower predictably-successful single-visit RCT.

Learning Objectives

After watching this presentation course attendees should know:

  • How and when to apply MIE principles to RCT cases and when to punt and cut a bigger access cavity to ensure success.
  • Which functional characteristics of file geometry and metallurgy contribute to rotary file negotiation and shaping with a very limited number of instruments.
  • How the functional dynamics of irrigation procedures can be optimized with cost-effective methods that minimize hands-on time requirements.
  • How to determine when single-cone obturation will achieve clinical objectives and when Centered Condensation is needed to move filling materials into extensive lateral spaces.
