A TMJ exam is the reviewing of the systems that move and support the temporal-mandibular joint. In our office, this has several componants:

1. We examine all the muscles and palpate the joints for discomfort. Healthy TMJs are not sensative to touch.
2. We listen to the movement joint with a Doppler. We are listening for bones rubbing and discs slipping. What we hear can also give us an idea of the health of the bone surfaces and the cartilaginous disc.
3. We also measure the range of motion that the jaw can move. Normal ranges are from 38-45 mm for women and 42-50mm for men.
4. Pain evaluation.

Healthy joints do not pop, click or hurt. If any of these conditions are present, or if other concerns are found during the exam, the patient may be referred for additional diagnostic x-rays, such as the I-CAT.
