Tests and diagnosis discussion for Jaw conditions:

Since the causes and symptoms of TMD are often unclear, diagnosis can be confusing and difficult. In about 90% of cases, the combination of the patient's description of symptoms, dental and medical history, and a physical examination of the face and jaw, can provide useful information for the diagnosis of these disorders.

The physical examination involves feeling the TMJ and chewing muscles for pain or tenderness; listening for clicking, popping, or grating sounds during jaw movement; and observing any limited motion or locking of the jaw while opening or closing the mouth.

Routine dental and TMJ x-rays are not always useful in the diagnosis of TMD, but may be helpful in few patients. Other x-ray techniques such as arthrography (x-rays of the joint using a dye), and magnetic resonance imaging (MRI, which pictures the soft tissues) are usually needed only when the practitioner strongly suspects a condition such as osteoarthritis or internal derangement of the TMJ, or when significant pain persists over time and symptoms have not improved with previous treatment.
