The purpose of this study was to examine the association between the symptoms of temporomandibular joint disorders and lumbar diseases in adults when the prevalence rate of osteoarthritis is increasing and to help develop health policies that can improve oral health and health in general. The study used representative data from the 5th Korea National Health and Nutrition Examination Survey phase 3 (2012). In total, we analyzed the data of 3,017 individuals aged over 50 years who participated in the health-related survey and underwent radiography of the lumbar joints. PASW statistics ver. 18.0 was used for analysis. This study revealed the following results: 16.1% experienced at least one symptom of temporomandibular joint disorders within the recent single year, 20.6% experienced lower back pain in the recent three months, and 30.6% had lumbar osteoarthritis revealed using radiography of the lumbar joints. Symptoms of temporomandibular joint disorders, lower back pain, and lumbar osteoarthritis were correlated with each other; the respondents who experienced symptoms of temporomandibular joint disorders had 1.70 times (95% confidence interval [CI], 1.30~2.22) higher prevalence of lower back pain and 1.20 times (95% CI, 0.86~1.68) higher prevalence of lumbar osteoarthritis than in those with no such difficulties. The results of this study confirmed that the symptoms of temporomandibular joint disorders affected lumbar diseases in adulthood. Therefore, adequate treatment and prevention of the symptoms of temporomandibular joint disorders in adults is expected to make crucial contributions to decreases in the prevalence rate of lumbar diseases and an improvement in the quality of life.

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.

Some treatment methods have been proposed for patients with chronic closed lock of temporomandibular joint. We report a conservative treatment for patients who had chronic closed lock of temporomandibular joint and who did not want surgical treatment. Two patients who had been treated in the Template clinic, Soonchunhyang University Bucheon Hospital, are the subjects of this report. The subjects had chronic closed lock symptom for over 3 months after an onset of locking; conventional therapies had no effect. The subjects were treated by making them wear a Template appliance while sleeping and exercise for 10 hours a day. After periodic follow-up, significant improvement was observed for Template treatment in terms of the maximal mouth opening range. When conventional therapy is expected to be ineffective, The Template appliance can be used as conservative treatment for temporomandibular disorders patients with chronic closed lock of temporomandibular joint.

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.

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.

A prevalence of temporomandibular disorders(TMD) based on the clinical sign and symptom in 155 patients were investigated. History taking with interview chart and clinical examination were performed. Age and gender of the patients, duration of TMD, location of pain, joint sound, limitation of mouth opening and more detailed diagnostic name were identified. The results of this study were as follows: 1. TMD was more prevalent in female than in male. TMD was the most prevalent at the age of 20s and decreased with age. 2. Acute TMD was more prevalent than chronic one. 3. About ninety percent of TMD patients had pain. Pain had mainly a unilateral origin. Muscle pain was mainly related with the masseter muscle. 4. Joint sound was identified in about fifty-six percent of the TMD patients and unilateral joint sound was more prevalent than bilateral one. 5. Limitation of mouth opening was observed in about forty percent of the TMD patients. 6. In TMD patients, muscle dysfunction was the most prevalent one. In muscle disorders local muscle soreness was the most prevalent one. In joint disorders, capsulitis was the most prevalent one. In muscle-joint disorders, trigger point pain with retrodiscitis was the most prevalent one.

Epidermoid cyst in bony wall of external auditory canal (EAC) is a very rare pathologic condition. In addition to its extreme rarity, its positional proximity to temporomandibular joint (TMJ) might lead to clinical misdiagnosis as TMJ disorders, especially when it is accompanied by temporomandibular disorders-like symptoms. In this article, we report a patient with epidermoid cyst in anterior bony wall of EAC, which was misdiagnosed as TMJ disorder because the left TMJ pain aggravated during mastication.

Temporomandibular disorders (TMDs) are diseases that affect the temporomandibular joint and supporting structures. The goal of treatment for TMDs is elimination or reduction of pain and return to normal temporomandibular joint function. Initial treatment for TMDs is non-invasive and conservative, not surgical. Oral and maxillofacial surgeons should fully understand and actively care about non-invasive treatments for TMDs. The purpose of this study is to review the validity and outcomes of non-invasive and surgical treatment modalities for TMDs.

Purpose: This study aims to examine correlation between temporomandibular disorder and oral habits that have been known to cause temporomandibular disorder with both male and female undergraduates. Methods: To figure out correlation between temporomandibular disorder and oral habits, a survey was conducted to 500 students of two universities located in Daegu Metropolitan City and Gyeongsangbuk-do, and excluding the ones unreliably answered or indicating errors, total 427 (85.4%) out of 500 questionnaire sheets were used for final analysis. Results: Female students showed higher prevalence rates than male students in temporomandibular joint pain and temporomandibular joint clicking, and students having the lip biting habit, tongue thrust habit, or bruxism habit indicated a higher prevalence rate of temporomandibular joint pain than normal students. Also, students having the tongue thrust habit indicated a significantly higher prevalence rate of temporomandibular joint clicking than normal students not having it. And about trismus, students having the bruxism habit showed a significantly higher prevalence rate than normal students not having it. Conclusion: The findings imply that oral habits like lip biting, tongue thrust, or bruxism are closely related with temporomandibular joint pain, tongue thrust influences temporomandibular joint clicking, and bruxism does affect trismus.
