title: Long-term evaluation of 211 patients with internal derangement of the temporomandibular joint.
abstract: This report is a long-term evaluation of 211 patients (158 women, 53 men) with TMJ clicking and/or TMJ incoordination, treated at the University Hospital of Copenhagen, Denmark, in the years 1971-77. Information on present symptoms and the effect of the initial treatment was obtained from questionnaires. Standard treatment procedures had been used in 153 patients while 58 patients had had counseling only. In the actively treated group, 59% were still doing well, 30% had unchanged symptoms and 5% experienced aggravated symptoms. In the counseled group, 40% were free of symptoms, 50% had unchanged symptoms and 7% aggravated symptoms. A highly significant association was found between the absence or presence of symptoms at the end of treatment according to patient records and the evaluation of the initial effect of treatment 8-15 yr later, which indicates that reliable results can be expected from a long-term evaluation of TMJ dysfunction patients. In the sample as a whole, the frequency of TMJ sounds was unchanged compared to the time of treatment (64% vs 66%). A significantly higher frequency was, however, found in the untreated group, indicating that treatment might have a positive effect on TMJ sounds. The frequency of recurrent headache had increased considerably over the years (6% vs 34%), 32% still experienced pain/tenderness on mandibular movement, 24% suffered from impaired mandibular mobility and 82% were aware of bruxism/clenching of teeth. Furthermore, we found a significant association between headache before treatment and headache, awareness of bruxism and clenching of teeth at the time of evaluation.(ABSTRACT TRUNCATED AT 250 WORDS)
