Dental Cone-Beam Computed Tomography (CBCT)

Cone-beam computed tomography (CBCT), also called digital volumetric tomography (DVT), is a method of cross-sectional imaging of teeth and tooth-bearing structures using X-radiation. It was first elaborated in 1990s for use in dentistry, but recently it is applied also in other fields of medical imaging, therefore the adjective Dental is also used to describe this technique. During exposure X-ray tube rotates around patient’s head emitting beam in the form of a cone—hence the name cone-beam computed tomography—or in form of a pyramid. During the exposure few hundreds of individual two-dimensional images differing in angulation are registered and saved as the so-called raw data, which serve as basis for image reconstruction performed by means of dedicated software. CBCT requires thorough knowledge of anatomy and pathology as well as skills to operate software and abilities to distinguish abnormalities in cross-sectional images. If correctly performed and evaluated, becomes an invaluable aid in numerous clinical cases in dental practice.
