The use of cone-beam computed tomography in dentistry

An advisory statement from the American Dental

Association Council on Scientific Affairs

The American Dental Association Council on Scientific Affairs

    The emergence of cone-beam computed tomography (CBCT) has expanded the field of oral and maxillofacial radiology. CBCT imaging provides three-dimensional volumetric data construction of dental and associated maxillofacial structures with isotropic resolution and high dimensional accuracy.

     A CBCT scanner uses a collimated x-ray source that produces a cone- or pyramid-shaped beam of xradiation, which makes a single full or partial circular revolution around the patient, producing a sequence of discrete planar projection images using a digital detector. These two-dimensional images are reconstructed into a three-dimensional volume that can be viewed in a variety of ways, including cross-sectional images and volume renderings of the oral anatomy.
