CONE BEAM COMPUTED TOMOGRAPH (CBCT)
​
Dental CBCT, standing for cone-beam computed tomography, is a more advanced form of a dental X-ray that gives dentists and prosthodontists more comprehensive information about the health and state of patients’ mouths, gums, and teeth.
​
Dental CBCT systems have been sold in the United States since the early 2000s and are increasingly used by radiologists and dental professionals for various clinical applications including, but not limited to, dental implant planning, visualization of abnormal teeth, evaluation of the jaws and face, cleft palate assessment, diagnosis of dental caries (cavities), endodontic (root canal) diagnosis, and diagnosis of dental trauma.
​
INFORMATION FOR PATIENTS ​
X-ray imaging, including dental CBCT, provides a fast, non-invasive way of answering a number of clinical questions. Dental CBCT images provide 3D information, rather than the 2D information provided by a conventional X-ray image. This may help with the diagnosis, treatment planning and evaluation of certain conditions.
​
The American Dental Association (ADA) and the FDA recommend that clinicians perform dental X-ray examinations, including dental CBCT, when necessary for the diagnosis or treatment of disease. The clinical benefits of a medically appropriate X-ray imaging exam do outweigh its small radiation risk.
​
The FDA also recommends that for all X-ray imaging procedures, including dental CBCT, patients and parents of children should:
-
Initially discuss the procedures with the health care provider.
-
Review the benefits and risks of the procedure.
-
Keep a record of your family’s medical-imaging histories.
