The Temporomandibular Joint (TMJ) X-ray is done to evaluate the joint and surrounding structures of the jaw for any abnormalities, such as fractures, dislocations, or degenerative changes.
When this test is required
A TMJ X-ray may be ordered by a dentist or a doctor when a patient has symptoms of jaw pain, difficulty opening and closing the mouth, clicking or popping sounds when the jaw moves, facial swelling, or a history of injury to the jaw.
What the Test Detects
The TMJ X-ray captures images of the temporomandibular joint and surrounding structures, including the jawbone, mandible, and the skull.
Preparation for the Test
No specific preparation is required for this test. However, you should inform the radiologist if you are pregnant, as the radiation may pose a risk to the developing fetus.
Sample Requirements
No sample is required for this test.
Additional Notes
The amount of radiation exposure from a TMJ X-ray is minimal and usually not harmful. However, pregnant women should avoid this test if possible, as the radiation may pose a risk to the developing fetus.
