![]() Please contact your physician with specific medical questions or for a referral to a radiologist or other physician. However, cone beam CT has the advantage of lower radiation exposure compared to conventional CT. It does not provide the full diagnostic information available with conventional CT, particularly in evaluation of soft tissue structures such as muscles, lymph nodes, glands and nerves. CT scans and cone beam CT both produce high-quality images.ĭental cone beam CT was developed as a means of producing similar types of images but with a much smaller and less expensive machine that could be placed in an outpatient office.Ĭone beam CT provides detailed images of the bone and is performed to evaluate diseases of the jaw, dentition, bony structures of the face, nasal cavity and sinuses. With cone beam CT, an x-ray beam in the shape of a cone is moved around the patient to produce a large number of images, also called views. However, dental cone beam CT can be used to produce images that are similar to those produced by conventional CT imaging. Images obtained with cone beam CT allow for more precise treatment planning.Ĭone beam CT is not the same as conventional CT. This type of CT scanner uses a special type of technology to generate three dimensional (3-D) images of dental structures, soft tissues, nerve paths and bone in the craniofacial region in a single scan. ![]() See the Safety page for more information about x-rays. ![]() It is not used routinely because the radiation exposure from this scanner is significantly more than regular dental x-rays. Dental cone beam computed tomography (CT) is a special type of x-ray machine used in situations where regular dental or facial x-rays are not sufficient.
