To evaluate the treatment outcome after conservative treatment in patients with TMJ disc displacement which is the most common temporomandibular joint arthropathy, the subjects were chosen among the patients who presented to the Department of Oral Medicine of Pusan National University Hospital, diagnosed as TMDs and treated with conservative methods from 1994 to 2006 for 13 years. 88 patients with diagnosis of DD/cR and 60 patients with diagnosis of DD/sR were selected as the experimental group and 74 patients with diagnosis of masticatory muscle disorder (MMD) were selected as the control group. Subjective symptoms and clinical findings were investigated to evaluate and compare the subjects’ status at the first visit and the last visit. The results were as follows;
1. Pain, noise, LOM and MCO measurements of DD/cR, DD/sR and MMD groups were markedly improved after conservative treatments including behavior therapy, physical therapy, medication and splint therapy.
2. At the first visit, high score of pain in MMD group, high score of noise and large MCO measurement in DD/cR group and high LOM score in DD/sR group were observed. At the last visit, high score of noise and increased MCO measurement in DD/cR group and high score of pain and LOM in DD/sR group were observed.
3. Among the patients who complained joint sound at their first visit, about 60% showed complete loss of joint sound after conservative treatment
4. DD/cR and DD/sR groups showed satisfactory outcomes after conservative treatments such as behavior therapy, physical therapy, medication and splint therapy while MMD group showed similar treatment outcome irrespective of the treatment modality used.
5. There was no difference in treatment outcomes after conservative treatments when the subjects were classified and compared according to gender, age group and chronicity.
6. MMD showed satisfactory prognosis in 10 treatments in less than 6 months while DD showed favorable prognosis in 10-20 treatments for 6 months to 2 years
