The recognition of craniomandibular disorders--an evaluation of the most reliable signs and symptoms when screening for CMD.

Two hundred and twenty-two patients who had been examined and treated for craniomandibular disorders were re-evaluated using a screening protocol. This protocol was developed from previous studies which had elucidated the most reliable signs and symptoms of craniomandibular disorders. Unilateral signs and symptoms were found to be more common than bilateral signs and symptoms. Dynamic and static pain tests were shown to be decisive in determining the preliminary diagnosis. There was a significant difference in vertical condylar height asymmetry between those patients diagnosed as having a myogenous and an arthrogenous origin of pain.
