What is this test?

This is a CT scan that uses X-rays and a contrast material given through a vein to create detailed images of the teeth, jawbone, and nearby facial structures. The exact area scanned and the imaging protocol may vary based on the reason for the examination.

Why might I need this test?

A dentist, oral surgeon, or other clinician may order this test to evaluate problems that are difficult to assess with a routine dental X-ray. Possible reasons include complex infection, jaw injury, unexplained bone changes, or planning for a dental procedure.

How is the test performed?

You lie on a CT table while an X-ray machine rotates around the area being examined. If intravenous contrast is used, it is usually injected into a vein in your arm, and the scan may be repeated with and without contrast depending on the examination plan.

How do I prepare for the test?

Follow the imaging center's instructions about fasting, medications, and arrival time. Tell the care team if you have previously reacted to iodinated contrast, have kidney disease, are pregnant or breastfeeding, or have other relevant medical conditions.

Frequently asked questions

What does this CT scan show?
It provides detailed cross-sectional images of the teeth, surrounding jawbone, and nearby facial structures. These images can reveal problems that may not be obvious on standard dental X-rays.
Why is intravenous contrast used?
Intravenous contrast can help highlight blood vessels, inflammation, infection, and certain tissue abnormalities. It also supports more detailed assessment of the area being scanned.
Do I need to do anything special before the test?
Preparation depends on the facility's instructions, and fasting may or may not be required. You should tell the care team about prior contrast reactions, kidney disease, pregnancy, breastfeeding, and relevant medication allergies before the scan.
