(Type V evidence - expert opinion)
5c. There is no evidence that the presence or extent of radiographic signs of pathology are of prognostic value in temporomandibular joint disordersi.

(Type III evidence - well designed non-randomised trial)
5d. A key outcome measure of the treatment of temporomandibular joint disorders (TMJ) is a stable functional TMJ with maximal intercuspation of the dentition. Success is dependent on the skills of the clinician in assessment as well as surgery, if indicatedi.

5f. Long term outcome of facial pain treatment is largely unknown. Research shows that conservative treatments including drug therapy and counselling are effective for 70% of patients. Refractory pain is associated with a long complex history of pain, a preoccupation with physical symptoms and poor psychosocial adjustment i.
