Objective: In patients with temporomandibular joint disorders, air insoles are used to investigate functionality and pain changes in the temporomandibular joint when walking in daily life. Intervention: Sixty-five patients with temporomandibular joint disorder were recruited: 34 as a control group who walked more than 7,000 steps a day in daily life, and 31 as an experimental group who were instructed to take at least 7,000 steps every day while wearing their air insoles. Measurements: To determine the effects of air insoles on temporomandibular joint pain, steady-state pain, maximum mouth opening, average pain, and the most severe pain were measured before and after the experiment. In addition, to evaluate functionality, the ability to open the mouth in a comfortable state, pain when opening the mouth, and the point of sound and maximum degree to which the mouth could be opened were evaluated before and after the experiment. Results: Pain, mouth openness, and sound points showed significant differences from the control group after the experiment, and the maximum mouth opening range showed no significant difference. Conclusion: When air insoles were used by patients with temporomandibular joint disorder, the functionality of the temporomandibular joint was improved and pain was decreased.

The purpose of this study was to investigate the association between characteristics of temporomandibular joint sound and possible contributing factors of temporomandibular joint sound. 1487 high school students (798 men and 689 women) aged from 16 to 18 were asked by questionnaires which was made for this study by T.M.J. clinic, dental infirmary, School of Dentistry, Chosun University, and data obtained from questionnaires were analyzed by chi-square test. The following results were obtained: 1. The prevalence of temporomandibular joint sound were found in 35.7% of all the subjects. 2. Temporomandibular joint sound could be unchanged, reduced and increased frequencey over time dependent on the individual. 3. The intensity of temporomandibular joint sound could be unchanged and increased during the chewing of hard food dependent on the individual. 4. The unilateral chewing and bruxism were not considered as possible contributing factors upon the occurring of temporomandibular joint sound. 5. Statistical significant association was found between clenching, stiffness, stress and tempore-mandibular joint sound, respectiely.(P<0.001, P<.01, P<0.05).

Purpose : This study was done to evaluate the absorbed doses in organs of the head and neck for the conventional temporomandibular joint tomography. Materials and Methods : Dosimetry was performed with 32 LiF thermoluminescent dosimeters, which were placed in a tissue-equivalent phantom when the temporomandibular joint was examined by both lateral and frontal temporomandibular joint tomography. Results : For lateral tomography, parotid gland and preauricular area towards tube showed relatively high absorbed dose of 1056.9 μGy and 519.9 μGy respectively. For frontal tomography, the two largest absorbed doses were 259.2 μGy in orbit towards tube and 212.0 μGy in lens towards tube. Conclusion : Conventional temporomandibular joint tomography showed relatively low absorbed doses on critical organs. Thus, responsible use of it may not be limited.

The author examined 206 temporomandibular disorders patients, who visited department of Oral Diagnosis and Oral Medicine in Seoul National University Hospital during the period from May 1st 1987 to April 30th 1988, clinically and radiologically and with prepared questionnaire. By clinical and radiological examination, the patients were divided into 2 groups(the patients with temporomandibular joint internal derangement and myofacial pain dysfunction syndrome or with myofacial pain dysfunction syndrome: the patient with temporomandibular joint internal derangement only). The symptom severity index and contributing factors were examined with the questionnaire, and differences in 2 groups were studied. The conclusions are followings : 1. The symptom severity index presenting the severity of symptom was higher and the scope of symptom was wider in the patients with temporomandibular joint internal derangement and myofacial pain dysfunction syndrome or with myofacial pain dysfunction compared to the patients with temporomandibular joint internal derangement only. 2. Emotions, behaviors, cognitions, and social factors were more undesirable in the patients with temporomandibular joint internal derangement and myofacial pain dysfunction syndrome or with myofacial pain dysfunction syndrome than the patients with temporomandibular joint internal derangement only.

A 69-year-old male pateint was admitted for discomfort on right temporomandibular joint during opening, closing and chewing that started few months ago. The patient had no special medical history except for lung tuberculosis approximately 30 years ago and nothing specific appeared on a physical exam taken 2 months ago. Clinical tests show that mouth opening of 53mm which was normal and no joint sound, deviation, pain during opening. But tenderness to palpation on Rt masseter muscle and pain existed on Rt temporomandibular joint during loading test on the right joint. No pain existed during resistance test and protrusion and range of lateral movement was normal. Rt temporomandibular joint was not swollen and no palpable mass was observed. No previous trauma history to the face existed. On X-ray calcific material existed in the joint cavity and on CT image, approximately 2mm sized calcific material appeared on the Rt temporomandibular joint but no change in bone appeared on the condyle nor the temporal bone. The patient was diagnosed as loose body, and the symptoms were relived after 2 physical therapies and is under regular check ups. The purpose of this case is to review disease that cause loose bodies.

The purpose of this study was to investigate the interrelationship between temporomandibular joint disorders, and the condyle size and angle of the posterior slope of the articular eminence. The subjects used in this study were 100 patients with temporomandibular joint disorders and 100 volunteers with normal temporomandibular joints. All the patients and the volunteers were subjected to take panoramic and temporomandibular radiographs for the morphologic evaluation. The films were traced, measured, and analyzed. The data were processed with SPSS/PC+ package for statistical analysis. The obtained results were as follows; 1. The posterior slope of the articular eminence in the group of temporomandibular joint disorders was larger than that in the normal group (p<0.05). The mean articular eminence angle was $31.6^{\circ}\;{\pm}\;6.3$ in the group of temporomandibular joint disorder, and $29.9^{\circ}\;{\pm}\;8.4$ in the normal group. 2. There were no statistically significant differences in the discrepancies of the left and right articular eminence angular measurements between the group (p>0.05). 3. There were no statistically significant differences in the condylar ratio between the groups (p>0.05). 4. There were no statistically significant differences in the discrepancies of the left and right ramus length measurements between the groups (p>0.05). 5. The relative size of condyle to fossa in the group of temporomandibular disorders was smaller than that in the normal group (p<0.05).

The aim of this study was to evaluate the influence of disc thickness on the normal behavior of the temporomandibular joint. Based on a specific patient case, CT scan images showing accentuated wear in the right disc were reconstructed and the geometrical and finite element model of the temporomandibular joint structures (cranium, mandible, articular cartilages and articular discs) was developed. The loads applied in this study were referent to the five most relevant muscular forces acting on the temporomandibular joint during daily tasks such as talking or eating. We observed that the left side structures of the temporomandibular joint (cranium, mandible and articular disc) were the most affected as a consequence of the wear on the opposite articular disc (right side). From these results, it was possible to evaluate the differences in the two sides of the joint and understand how a damaged articular disc influences the behavior of this joint and the possible consequences that can arise without treatment.

In order to propose a fundamental and appliable theories for balancing therapy of temporomandibular joint (TMBT), evolutionary proofs and up-down theories in evolutionary biology and Korean medicine were investigated. Balancing therapy of temporomandibular joint treats disorder and diseases of the whole body through straightening of the abnormal linking between temporomandibular joint and axis. Although the mechanism of this therapy contains many merits like multicellular integrity and coadjustment, ease of balance and alert forward mobility by the bipedal stepping and evolution to Homo sapiens, increasing disadvantages of balancing pressure of right and left in the lengthened perpendicular axis and the balancing load of temporomandibular joint and axis following the reactional change of dental occlusion are deeply related and considered in this therapy. As for up-down theory, crossing of heavenly qi and earth qi centering on cervical joint is presented as the first mechanism for TMBT, and the other ones like in-out and up-down qi activity of tripple energizer, up-down of essence-qi-spirit in the three backbone barrier and three cinnabar field, up-down of yin-yang-water-fire of viscera and bowels can be related too.
