초록
The authors analyzed the clinical findings, radiological findings and their correlations in the temporomandibular joint disorders. The results were as follows: 1. The most prevalent age group was in the first decade, then the second decade and the third decade. Female were more common with a ratio of 3.4:1. 2. The most common clinical findings was the pain on open mouth position (42.3%), then came the clicking and limitation of mouth opening. 3. The most common bone change on the condyle side was the erosion, then came the flattening, the osteopyte and the sclerosis in that orders. 4. In the case of the crepitus, the coarse crepitus showed more radiological change than the fine crepitus. The 27% of the patients with crepitus showed the bone change and the patients with crepitus showed more bone change than any other clinical symptoms. 5. In the case of the mouth opening limitation, the evaluation of the translatory movement by transcranial projection was in accordance with the clinical evaluation. 6. The correlation between the clinical symptom and the condylar position within the mandibular fossa was not present and in the case of diagnosis of disc displacement, the transcranial projection seemed not to be able to substitute for the arthrography. Radiographically, the most prevalent age group which showed the bone change was in the first, the second and the third decade. And the bone change seemed to have no relationship with aging.
