Course Description

Cone Beam Computed Tomography (CBCT) has become an indispensable diagnostic imaging tool in clinical endodontics. In particular, high-resolution limited field of view 3D imaging volumes of the jaws provides dentists with greater diagnostic accuracy for tooth and root morphology and tooth and bone-related pathology than regular intraoral digital 2D imaging. CBCT imaging’s challenge is the users’ lack of training and understanding of basic and advanced imaging principles. After all, when reading a scan, there are known knowns; there are imaging patterns that we know that we know. There are known unknowns; that is to say, there are things regarding 3D imaging that we know that we don’t know, and there are the unknown unknowns or 3D imaging things that we do not know we don’t know. Using clinical cases, we will demonstrate how to use this imaging modality better and discuss the impact of recognizing 3D imaging patterns associated with endodontic scans and newly developed task-specific rendering and realistic 3D rendering filters dentistry.

Learning Objectives

  • Learn the importance of high resolution scans in your daily practice
  • Understand the importance of systematic imaging interpretation
  • How to navigate 3D volumes and avoid parallax error
  • How to optimize imaging for endodontic interpretation
