What is a Dental CT Scan?
A Dental CT scan, also known as CAT scan of the mandible and maxilla, is a painless radiology exam. This is performed to examine the lower jaw (mandible) and the upper jaw (maxilla) in a non-invasive manner. This scan is also known as Dental Cone Beam Computed Tomography (CBCT) Scan.
The Dental CT Scan helps dentists or oral surgeons in identifying problems in the teeth and jaws such as fractures or tumors. It also helps them in assessing face bones for difficult tooth removals and placement of dental implants.

What Is the Purpose of a Dental CT Scan?
Your dentist may order a Dental CT Scan to:
- Locate the origin point of jaw pain
- Detect injury, infection, tumor, or other abnormalities in the jaw area
- Determine bone structure and tooth orientation for dental implants
- Diagnose temporomandibular joint (TMJ) disorder that causes pain in the jaw joint and the muscles that control jaw movement
- Evaluate the jaw, nerve canals, sinuses, and nasal cavity
- Do surgical planning for impacted teeth
Your doctor may also recommend a Vitamin D 25-OH test to check the Vitamin D level in your blood. Deficiency of Vitamin D can severely affect your dental health and therefore, this test will help your doctor determine the correct course of treatment.
How Is a Dental CT Scan Performed?
- Before starting the dental CT scan, you will have to remove all the metal objects on your body, including eyeglasses, jewelry, hairpins, and dentures.
- Your dentist or oral surgeon will ask you to either sit still in the exam chair or lie down on the CT scanner table, depending on the type of CT scanner being used.
- Your dentist or oral surgeon will position you, so that the area of interest is centered in the beam.
- The x-ray source and detector will move in a circle around you and will take multiple images that will be displayed on a monitor.
- Make sure you don’t move during the scan as any movement can blur the images.
How Long Does a Dental CT Scan Take?
A Dental CT scan is usually completed within 10 to 15 minutes.
Is Radiation Involved in a Dental CT Scan?
Yes. CT Scan is an imaging test, which involves a small amount of radiation to show images of the organs, tissues, and bones of the body.
When Will I Receive My Results?
Once the cone beam dental scan is completed, you will receive your results within 3-5 business days in your LabFinder portal.
