Examples
Degenerative joint disease, such as osteoarthritis or organic degeneration of the articular surfaces, recurrent fibrous or bony ankylosis, developmental abnormality, or pathologic lesions within the TMJ.
Diagnosis Modern digitalised panoramic X-ray devices are capable to take TMJ images, which provides information about articular fossa and condyle.
McNeill 1997 described TMD diagnostic criteria as follows: * Pain in muscles of mastication, the TMJ, or the periauricular area (around the ear), which is usually made worse by manipulation or function.
Clicks of the joint may also be palpated, over the joint itself in the preauricular region, or via a finger inserted in the external acoustic meatus, which lies directly behind the TMJ.
Due to the proximity of the ear to the temporomandibular joint, TMJ pain can often be confused with ear pain.
Each TMJ is covered by a fibrous capsule.
