Course Description: Employing a gutta percha coated instrument for root canal obturation has been an accepted technique for over 30 years, but its popularity is not universal within the ranks of dental professionals. There is still widely held skepticism as to the materials efficacy and appropriateness in certain clinical scenarios, along with adverse experiences with the material. Misinformation, misapplication, and miscalculation of the materials’ capabilities have all served to perpetuate an undeserved reputation. This course will serve to address all concerns about not only the didactic science and research of carrier-based obturation, but also the correct protocols for successful clinical placement. Following a lecture component, participants will practice using size verifiers, gutta core ovens and gutta core obturators on gutta core prepared blocks.

Learning Objectives:

At the conclusion of this presentation, participants will be able to:

  1. Discuss and critique the existing literature base as to the validity of the results and conclusions presented.
  2. Explain the correct protocols for canal preparation and carrier size selection.
  3. Describe the diagnosis and placement of the materials in anatomically challenging scenarios such as bifurcated, elongated and overly broad canal spaces.
