One of the most significant advances in dentistry in recent years is the availability of 3-D imaging. Since the introduction of conebeam computed tomography (CBCT) in the U.S. in 2001, the technology has grown at an unprecedented rate showing 100 percent growth per year in the last few years. The application of this technology has been widespread involving every dental discipline. CBCT imaging seems particularly suited for comprehensive evaluation of child and adolescent patients. This presentation covers important topics in 3-D imaging using case examples and evidence-based findings. CBCT, what it is and what it is not? What is the need for advanced imaging? This session also focuses on radiation safety, the fundamentals of 3-D visualization, and the role of technicians.
