Cone-beam computed tomography (CBCT) is an advanced imaging modality that has high clinical applications in the field of dentistry. CBCT proved to be a successful investigative modality that has been used for dental and maxillofacial imaging.
Radiation exposure dose from CBCT is 10 times less than from conventional CT scans during maxillofacial exposure. Furthermore, CBCT is highly accurate and can provide a three-dimensional volumetric data in axial, sagittal and coronal planes.
Cone beam computed tomography (CBCT) is a radiographic imaging method that allows accurate, three-dimensional (3D) imaging of hard tissue structures. CBCT is the most significant among the medical diagnostic imaging modalities that have emerged recently. This imaging modality is capable of providing sub-millimeter resolution (2 line pair/mm) images of higher diagnostic quality, with shorter scanning times (~60 s).
Radiation exposure dose from CBCT is 10 times less than from conventional CT scans during maxillofacial exposure (68 µSv compared with 600 µSv of conventional CT) and also it has got great dimensional accuracy (only about 2% magnification). Increasing availability of this technology is now providing the dental clinician an imaging modality, which is capable of providing a 3D representation of the maxillofacial structures with minimal distortion and reduced radiation hazards.
