How the Test Works

During this test, you’ll lie down on a table while a low-dose X-ray machine scans your jaw. The machine uses two different energy levels to create detailed images of your bone density. The results are compared to standard values to determine how your bone compares to a healthy person.

Preparation

No special preparation is needed. You may wear your usual clothing, and you’ll be asked to remove any jewelry or metal objects that could interfere with the scan.

What to Expect During the Test

The test itself is quick and painless. You’ll feel a gentle pressing sensation as the scanner moves across your jaw. The entire procedure usually takes about 10 minutes.

Results and Follow-Up

Your results will be reviewed by a healthcare provider who specializes in bone density. They may compare your findings to your previous scans or to healthy reference values to determine if your bone density is normal or if further action is needed.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Why was I asked to have this test?
Your doctor may recommend this test if you have risk factors for low bone density, such as being postmenopausal, having a history of osteoporosis, or taking medications that can affect bone health. It may also be used to monitor your progress if you’re undergoing treatment for bone-related conditions.
What does the test measure exactly?
The test measures the density of the mineral content in your left jawbone. This is done using a specialized X-ray technique called Dual-Energy X-ray Absorptiometry (DXA). The results are expressed in units that compare your bone density to a standard reference.
Will the test hurt?
No, the test does not cause pain. You may feel a slight pressure as the scanner moves across your jaw, but it is generally comfortable and temporary.
