Emotional factors in temporomandibular joint disorders.

The chronic pain of many temporomandibular disorders is associated with multiple changes in emotional function and activities of daily living. Temporomandibular disorders (TMD) are similar to other chronic pain disorders in their impact on patients. Depression is probably the most common emotional state associated with chronic pain, although anxiety disorders also can be associated with TMD. The probability of emotional problems appears to be greatest in those individuals diagnosed with myofascial pain and least in those with disk displacement. Dental practitioners are encouraged to seek professional liaisons with mental health professionals who can assist them in managing chronic pain patients.
