The authors examined the condylar position and shape of condylar process from the transcranial radiographs and polytomographs of the 130 temporomandibular joints of 65 patients who complained symptoms of temporomandibular disorder and the followings were obtained; 1. The age and sex distribution of the 65 patients showed peak incidence in 2nd decade (27.7％) followed by 3rd (18.5％) and 4th decade (18.5％) and female predominance (87.7％). 2. In polytomography 64 joints (49.2％) showed consistent condylar position from lateral to medial and 39 joints (30.0％) of them showed agreement with those of transcranial radiographs. Among the 66 joints (50.8％) which showed changes in condylar position. 48 joints (36.9％) showed agreement with lateral and central tomographic and transcranial radiographic position. 41 joints (31.5％) showed disagreement in condylar position between the polytomographic and transcranial radiographic images. 3. When the condylar position was classified as anterior, central and posterior. the posterior position was the most frequent position, that is . 42.3％ of the transcranial radiography and 42.3％.49.2％ and 38.5％ of the lateral, central and medial polytomographic radiographs. 4. In polytomography 84 joints (64.6％) showed consistent condylar shape from lateral to medial and 74 joints (56.9％) of them showed agreement with those of transcranial radiographs. Among the 46 joints (35.4％) which showed changes in condylar shape. 40 joints (30.1％) showed agreement with lateral and central tomographic and transcranial radiographic shape. 41 joints (31.5％) showed disagreement in condylar shape between the polytomographic and transcranial radiographic images.

Although most cases of tension-type headache(TTH) are myogenic headache, in some cases, arthralgia appears, such as the disorder of the temporamandibular joint. This study is designed to compare the clinical patterns of arthralgia to those of myalgia, when both symptoms are co-existing. Among 167 patients who visit our clinic during a certain period, whose chief complaint was TTH, 18 patients were the arthralgia group, 50 patients were the myalgia group, and 99 patients who have both arthralgia and myalgia were the arthromyalgia group. Three groups were asked to answer the questionnaires about their age, gender, and oral parafunction such as bruxism or clenching. Then we gathered statistics on the data from the accomplished questionnaires. 1. There was statistical significance in age among the three groups(p=0.02). 2. There was no statistical significance in sex and oral parafunction among the three groups. 3. There was statistical significance the myalgia group was older than the arthromyalgia group(p<0.03). The results of the study show that as patients become older, TTH with myalgia happens more frequently than TTH with arthralgia and myalgia does.
