An attempt was done to evaluate clinical figures in the first examination of mandibular dysfunction patients with two or more symptoms of temporomandibular joint (TMJ) pain, TMJ sounds and limitation of mandibular movement followed by no organic change in the TMJ. The results were as follows:
1. A great prevalence of female was seen and the ratio of female/male was 9 to 1.
2. In age distribution, the patients of 10 years old to 19 and 20 to 29 were predominant.
3. Most patients were treated by restorative therapies and few of them had experiences of several general diseases.
4. Evaluating the chief complaints associated with the first symptoms, TMJ pain was much predominant in comparison with TMJ sounds.
5. Clinical symptoms were expressed by TMJ pain, TMJ sounds and limitation of mandibular movement with other symptoms as headache, neck and shoulder pain and ear symptoms.
6. Most patients had natural dentitions. Premature contacts were seen in centric relation in all patients and more than half of them had occlusal interferences in eccentric relations.
7. The remarkable presence of oppressive pains in masticatory muscles was observed. The finding that factors which might be associated with muscle tensions were seen in many patients suggest the correlation between mandibular dysfunction and muscle hyperactivity.
