Since its introduction to dental radiology in 1998, cone-beam computed tomography (CBCT) has been subject to a wealth of scientific reports. The two preeminent queries attempted to be answered are its degree of accuracy in the craniofacial region and the radiological burden of a CBCT examination. The pertinent literature on accuracy can roughly be divided into three groups. Some studies evaluate the influence of device properties and settings, thereby altering voxel-size, varying beam properties (such as kilovoltage, milliampere, field of view, number of projections) or using different post-processing techniques and software. Other studies evaluate the impact different regions of interest have on CBCT accuracy.
