Is a CBCT Scan High in Radiation?

Dental CBCT scans generally use less radiation than conventional medical CT scans, although the dose varies depending on the equipment, scan area, and settings.

At our office, we use the Vatech Green X 21, which offers low-dose imaging options. We select the scan area and settings based on your diagnostic needs to obtain clear images while minimizing radiation exposure.

What Are the Downsides of Using CBCT?

CBCT provides detailed 3D images, but it has some limitations:

  • Radiation exposure: CBCT uses ionizing radiation, typically at a higher dose than standard dental X-rays. Scans should be taken only when the information is expected to benefit your care.

  • Limited soft-tissue detail: CBCT is useful for evaluating teeth and bone, but it does not clearly show the TMJ disc, muscles, or other soft tissues. An MRI may be needed to evaluate these structures.

  • Image distortion: Metal fillings, crowns, implants, and movement during the scan can create artifacts that obscure details.

CBCT findings must be interpreted alongside your symptoms and clinical examination. A scan alone cannot identify every cause of jaw or facial pain.
