Imaging has always been, and will continue to be, a central technology behind decision-making and outcome assessment in endodontics. However, as this technology changes, so must our interpretation of the imaging itself. CBCT images are radically different from periapical projection radiography, and their interpretation is informed by our perception and cognition, which is by no means perfect. Conventional methods of radiograph interpretation cannot be extended to CBCT imaging, so this book encourages endodontists to develop a sound technical and theoretical understanding of CBCT. The authors compare the capabilities of modern CBCT imaging with traditional radiography and also present vital information about image interpretation and perception to increase competence and confidence in CBCT interpretation and minimize overdiagnosis and subsequent overtreatment.
