Purpose: To evaluate the effectiveness of temporomandibular joint (TMJ) disorder follow-up and determine the factors that affect the TMJ bone scan hot spot numerical value (bone scan value), and to compare this value to the diagnosis of patients with temporomandibular joint disorders (TMD), their treatment options, and the resolution of their symptoms. Materials and Methods: A retrospective cohort study was performed on 24 patients (four males, 20 females) who received TMD treatment in the Section of Dentistry, Seoul National University Bundang Hospital (Seongnam, Korea) from 2007 to 2014. An analysis of the significance test and correlation between TMD diagnosis, treatment options, a baseline the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire, treatment before and after the clinical examination and subjective progress, and TMJ bone scan value change were completed by using SPSS version 12.0. Result: Although only 14 patients had bony factors that caused TMD, the average pre-treatment bone scan value of the all patients was $4.29{\pm}0.31$, which is higher than the finding for osteoarthritis (3.88), and reduced post-treatment bone scan value was found to be without a statistically significant difference (P=0.056). After the treatments, clinical symptoms in 18 patients disappeared, and six patients did not require additional treatment, although they still displayed subjective symptoms. It was observed that the higher the pre-treatment bone scan value, nonspecific physical symptoms, chronic pain index, characteristic pain intensity, disability score, were, the lower the post-treatment bone scan value was. And this reduced post-treatment bone scan value tendency was not shown with the pre-treatment depression index, but there was not a statistical difference. Conclusion: The post-treatment TMJ bone scan value tended to be insignificantly reduced in the 24 patients whose clinical symptoms were improved (P=0.056). Moreover, the TMJ bone scan value showed no relation to the TMD type or its related symptoms.

Objectives: The purpose of this study was to analyze Influence of stress on oral health and quality of life. Methods: The participants were 172 students from 4 universities located in DaeJeon, South Korea. A questionnaire was administered, assessing the impacts of the general characteristics of the participants, temporomandibular joint (TMJ) symptoms, xerostomia, and halitosis on stress. And oral impacts on daily performance were also investigated. Data were analyzed using the Statistical Package for the Social Sciences 18.0. Results: The level of stress was higher in female, and the causes of stress was reported scholastic achievement, relations with professors, get a job. The students who were higher stress were more conscious of TMJ symptoms, xerostomia and halitosis(p<0.05). Stress was significantly positively correlated with TMJ symptoms (r=0.376, p<0.001), dry mouth (r=0.360, p<0.001), and bad breath (r=0.343, p<0.001). Oral Impacts on Daily Performance (OIDP) scores were significantly positively correlated with dry mouth, bad breath, TMJ symptoms, and stress. Regression analysis showed that 54.5% of the independent variables were related to OIDP scores. Stress and TMJ symptoms exerted a significant effect on OIDP scores. Conclusions: Stress among university students affects oral health and quality of life. Stress coping mechanisms and oral health care education programs should be developed and applied at universities.

The author examined the clinical signs and symptoms , routine radiographs, laboratory test and bone scan in 73 subjects with TMJ disorders and studied the responses of clinical test on patients, the distribution of signs and symptoms of joints, the simple uptake rate(SUR) of affected joints , the SUR of subclassified groups of TMJ disorders, active joints of subclassified groups of TMJ disorders and the SUR of joints with noises. The obtained results were as follows : 1. The percentage of joint pain on palpation, joint noises joint pain on function, mandibular dysfunction and active finding of bone scan in aptients with TMJ disorders were higher 2. The SUR was higher in joints affected by joint pain on function, joint pain on palpation, mandibular dysfunction and creptius. 3. The SUR of osteoarthrosis was the lowest. 4. The percentage of active joints were the highest in joints with discdisplacement without reduction, and followed by osteoarthritis, and disc displacement with reduction. 5. The SUR of TMJ showing joint noises only was lower.

Objectives : The purpose of the study is to investigate the relationship between job-stress and temporomandibular joint(TMJ) disorder in dental hygienists. This study will provide the basic data to improve the working condition and the quality of life. Methods : The subjects were 229 dental hygienists at general hospitals in Seoul, Korea. A self-reported questionnaire was filled out from May 20 to June 20, 2013. The questionnaire consisted of 4 questions of demographic features, 11 questions for TMJ symptoms and 5 questions for job stress. The data were analyzed by frequency analysis, chi-square test, Mann-Whitney U test and multiple job-stress logistic regression analysis using SPSS version 21.0. Results : During the last six months, 53.3%(122 persons) of the dental hygienists had TMJ disorder symptoms including joint noise(40.6%, 93 persons), TMJ pain(31.4%, 71 persons) and limitation of TMJ(21.8%, 50 persons). Job-stress is divided into two ranges including high stress group(4.3-5.0 points) and low stress group(0.0-3.6 points) in TMJ pain and joint noise(p<0.05). TMJ pain was closely related to low back pain, pelvis pain and tension headache arising from the uncomfortable working posture. Conclusions : It is necessary to prevent the job stress in the dental hygienists by the improvement of working condition, emotional stability, and frequent postural change.

The author analysed the routine radiographic changes and clinical symptoms of 205 cases of temporomandibular joint arthrosis. The clinical symptoms of the patients were classified and the morphological ylar head, articular eminence, and articular fossa were analized and discussed view point. The positional changes of condylar head and articular fossa relatation in TMJ arthrosis were observed. The frequencies of coincidence between the site of complaints and the site of the abnormal images which could be detected were examined. The results were obtained as follows; 1. Bone erosion, deformity, marginal proliferation and sclerosis were selected from many abnormal images as the radiographic diagnostic criteria of TMJ arthrotic lesions. 2. Abnormal radiographic findings were revealed in 150 cases (73.9%) of 205 total TMJ arthrosis cases and site with abnormal findings coincided with the site of complaints in 106 cases (70.7%) of 150 cases and coincidence rates were higher above fourth decades than below third decades. 3. Sclerosis of the abnormal radiographic findings could be found more often below third decades than above fourth decades. 4. The positional changes of condylar head were revealed in 176 cases (85.9%) of 205 total cases. 5. Pain complaints were revealed in 170 cases(82.9%) and clicking sounds were revealed in 120 cases (58.6%) of clinical symptoms of TMJ arthrosis. 6. No tendency was found so far the differential diagnosis between pain dysfunction syndrom and osteoarthrosis of TMJ.

Purpose : To determine the relationship between clinical symptoms and magnetic resoncance (MR) images in patients presenting with temoporomandibular joint (TMJ) disorders. Materials and Methods: This study was based on 172 joints in 86 patients presenting with TMJ disorders. Joint pain and sound during jaw opening and closing movements were recorded, and the possible relationship between disc positions and bony changes of the condylar head and the articular fossa in MR images in the oblique sagittal planes were examined. Data were analyzed by Chi-square test. Results : There was no statistically significant relationship between clinical symptoms and MR images in the patients with TMJ disorders. Conclusion: In the patient with TMJ disorders, joint pain and sound could not be specific clinical symptoms that are related with MR image findings, and asymptomatic joints did not necessarily imply that the joints are normal according to MR image findings.

본 저자는 하악지시상분할법이 측두하악관절장애와 관련되어 교합의 개선과 과두의 위치적변화에 어떤영향을 미치는가에 관해 연구하고자하여 다음과 같은 결과를 얻었다. 측두하악관절증상은 약 80%에서 개선되었으며 이는 아마도 부정교합의 개선으로 일어난 것이 아닌가 생각된다. 하악지 시상분할술에 있어 측두하악관절의 구조적 변화가 야기되는데 이것이 관절의 기능에 어떤 변화를 주어 측두하악관절증상과 관련해서 발생되는 것으로 추정되고 단기 추적조사와 비교해 볼 때 장기추적조사 결과 하악두위치변화에도 불구하고 Range of adaptation이 환자 개개인에 존재하는 것이 아닐까 생각된다. 이와 같은 결과를 종합해볼 때 경미한 측두하악관절증상을 동반한 하악전돌증환자에서 악교정수술을 시행함에 있어 개인의 하악두의 위치를 지켜주어 부정교합의 개선과 정상적인 관절기능을 유지시켜주는 것이 회귀성향과 관련하여 중요한 요소가 아닌가 생각되며 회귀성향과 하악두의 위치관계 또 측두하악의 증상등을 연관하여 더 진행된 연구가 필요하리라 사려된다.

Objectives: The aim of this study was to review main symptoms of outpatient in Lee young Jun clinics who developed the functional cerebrospinal therapy and to investigate the therapeutic effects on one time application of functional cerebrospinal therapy (FCST). Methods: Patients who visited at least twice at an oriental medical clinic and treated with FCST were included. They were asked to write 216 numeric rating scale (NRS)-based questionnaire about degree of various symptoms at each visit. Prevalence and degree decrease of all reported symptoms were analyzed. Results: Total of 744 outpatients were included. There were fourteen symptoms of which more than half of all patients commonly complained. All symptoms were significantly reduced after one administration of FCST. About four to seven percent of patients reported at least five-point reduction on NRS in each symptom after FCST. Conclusions: FCST might have potential immediate effect on not only TMJ related symptoms, but also diverse kinds of pain, psychological symptoms, and fatigue-related symptoms.

Purpose : To determine the clinical correlation of magnetic resonance imaging (MRI) findings of temporomandibular joint internal derangements. Materials and Methods : The MR images of 150 TMJs in 75 patients were analyzed. The clinical symptoms were pain in the preauricular area and masticatory muscles and TMJ sounds. Results : There was a statistically significant relationship between the MRI diagnoses of different types of disc displacements and clinical findings of pain, clicking, and crepitus. The risk of TMJ pain was increased when the disc displacement without reduction occurred at the same time in combination with the osteoarthrosis and effusion. Conclusion : Regardless of the results, the data indicate that each of these MR imaging variables may not be regarded as the unique and dominant factor in defining TMJ pain occurrence.
