  • Abstract

    It has been more than a century since William Conrad Roentgen first discovered the X-ray. Radiology has transformed itself from scientific curiosity to a medical and dental necessity. The evolution of radiographs from periapical to extraoral imaging, and cephalometric, and panoramic radiography has heralded major progress in dental radiology, providing clinicians with a single comprehensive image of the jaws and maxillofacial structures. Even though radiograph is useful in certain ways, it has its own pros and cons. Exposure to X-ray beam radiation for prolonged period can result in the development of cancer and other adverse effects. Cone-beam computed tomography (CBCT) is an advanced medical imaging technique that generates three-dimensional (3-D) image at a lower cost and absorbed dose compared to that of conventional CT. This technique is based on a cone-shaped X-ray beam centered on a two-dimensional (2-D) detector that performs one rotation around the object, producing a series of 2-D images. These images are reconstructed in 3-D using a modification of the original cone- beam algorithm developed by Kamp et al., in 1984. Interest in CBCT from all fields of dentistry has been unprecedented, as the results of a 3D visualization provided improved interpretation, diagnosis, and treatment planning. It also showed a tremendous impact in dental implant treatment planning, giving the arch and ridge configuration, and location of the nerve and maxillary sinus before the surgery, thereby decreasing surgical uncertainty. Many innovative software programs are useful in making customized surgical guides, virtual models, and laser-generated resins for treatment planning. This article describes CBCT generations, advantages, disadvantages, and the various applications of CBCT in dentistry.
