Article
Cone Beam Computed Tomography (CBCT) first became commercially available in the early 2000s and has revolutionized the practice of dental and maxillofacial radiology. When three-dimensional imaging is required of the teeth and jaws, CBCT is often the modality of choice within both the primary and secondary dental care setting.1 The aim of this article is to provide the general dental practitioner with information on relevant legislation, CBCT equipment, and the advantages and disadvantages of the technique. In addition, indications and contra-indications, image interpretation and training requirements will be discussed.
CBCT utilizes a pyramidal-shaped X-ray beam rotating around the patient to gather information which is reconstructed into a cylindrical 3D image. Scan parameters that can be changed include the field of view (FOV), pixel (voxel) size (0.075 mm–0.4 mm), scan time, the degree of X-ray beam rotation (360° or 180°), X-ray tube potential (kilovoltage, kV) and X-ray tube current (milliamperage, mA). Changing these parameters can affect the image resolution and the patient dose.2,3 Scanning parameters are dependent on the indication for irradiation and should be assessed and justified on an individual basis. The Ionizing Radiation (Medical Exposure) Regulations 2000 IR(ME)R As Low As Reasonably Achievable (ALARA) principle should be applied to all ionizing radiation exposures.4,5
