Temporomandibular disorders(TMD) have been defined as a collective term embracing a number of clinical problems that involve the temporomandibular joint, the masticatory muscles, and associated structures. Since Dr. James Costen has mentioned about the relationship between TMD and posterior bite collapse, there have been many controversies about the etiology and comorbidities of TMD. The purpose of this study was to investigate the relationship between TMD and hearing acuity in 158 volunteers with or without TMD symptoms. The subjects were examined clinically about TMJ sound, missing teeth, tinnitus, TMJ pain and masticatory muscle pain and the hearing acuity were measured by Audiometer(ITO AE-1000, Japan). The result of this study indicated that there was no significant differences between TMD symptoms and hearing acuity relatively.

Purpose: This study was performed to investigate the relationship between temporomandibular disorders (TMDs) and the asymmetry of the mandibular height. Methods: We compared 100 randomly selected TMD patients diagnosed by the research diagnostic criteria for TMD (RDC/TMD) Axis I with 100 non-TMD control subjects matched with the TMD patients in age and gender. The mandibular heights were measured on an orthopantomogram and the asymmetry index (AI) was calculated as previously described. Results: The absolute AI value of 4.37% turned out to be the least cut-off value defining asymmetry, which showed a significant difference in asymmetry incidence (p<0.01) between the TMD and control groups. The risk of TMD increased in the asymmetry group by 4.57 (odds ratio). The incidence of asymmetry was not related to age and gender in both of the TMD and control groups. When dividing the TMD group according to the RDC/TMD Axis I diagnosis, neither the incidence of muscle disorder nor disk displacement was related to the incidence of asymmetry. However, a higher incidence of asymmetry was observed in the subjects classified into the arthrosis/arthritis groups (p<0.01). Conclusions: Although it does not imply a direct cause-and-effect relationship, asymmetry resulting in more than 4.37% difference between mandibular heights may increase the risk of TMD and correlates positively to the incidence of arthritic change in the temporomandibular joint of TMD patients.

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.

Temporomandibular disorders refer to a large group musculoskeletal disorders that originate from the masticatory structures. The AADR recognize that temporomandibular (TMDs) encompass a group of musculoskeletal and neuromuscular conditions that involve the temporomandibular joints (TMJs), the masticatory muscles, and all associated tissues. The signs and symptoms associated with these disorders are diverse, and may include difficulties with chewing, speaking, and other orofacial functions. They also are frequently associated with acute or persistent pain, and the patients often suffer from other painful disorders. The chronic forms of TMD pain may lead to absence from or impairment of work or social interactions, resulting in an overall reduction in the quality of life. However, the consensus of recent scientific literature about currently available technological diagnostic devices for TMDs is that, except for various imaging modalities, none of them shows the sensitivity and specificity required to separate normal subjects from TMD patients or to distinguish among TMD subgroups. This article reviews the various instruments to aid in the diagnosis of TMDs, and the overall validity and practical use of the Electromyography.

측두하악장애(TMD)는 측두하악관절, 저작근 및 주변 구조물과 관련된 많은 임상적 문제들을 포괄하는 집합적인 용어로 정의되어 왔다. 1934년 이비인후과의사인 Costen이 턱 내측과 주변부의 통증 및 관련된 귀 증상이 교합의 변화로 개선되었다고 주장하는 논문을 발간한 이후, 턱관절장애의 진단과 치료는 교합이라는 개념 안에 속해 있었으나, 이에 대한 대부분의 최근 저서들은 교합장애를 더 이상 그 범주에 포함시키지 않고 있다. 측두하악장애 영역에서 교합장애를 배제시키려는 이러한 경향에도 불구하고 측두하악장애와 교합치료와의 유대는 여전히 강력하다. 현재 측두하악장애의 병인에 관한 가장 대중적인 이론들은 사회심리생물학적 모형에 기반을 두고 있으며 따라서, 향후의 치료방식들은 관절 및 근육 통증의 병태생리학적 과정뿐만 아니라, 만성 통증의 사회심리적 측면들까지도 그 대상으로 해야 할 것이다.

Various conditions such as pain or effusion of temporomandibular joint, degenerative condylar resorption, and articular disc displacement can be a cause of malocclusion. However, the reasons of occlusal changes are ambiguous in some patients. Unexpected occlusal change in patients with or without temporomandibular disorder (TMD) symptom was mostly caused by masticatory muscular disorders. This article reports two cases of recovery of occlusal relationship in TMDs patients after stabilization splint therapy. Stabilization splint therapy could be useful in certain conditions of occlusal changes in TMD.

Objectives : This study aimed to investigate relationship between the psychological factors, the prevalence, and perception of temporomandibular disorder in Korean adults. Methods : A total of 7203 data were derived from Korean national health and nutritional examination survey. All data were analyzed using R-COMMANDER(12.2 SDI) program. Results : The prevalence of temporomandibular disorder in Korean adults was 3.1% and 10.5% of adults with temporomandibular disorder (TMD) had more than one TMD related symptom. Women had higher prevalence rate of TMD related symptom than men. Prevalence rate in TMD was low in the younger age, the higher education level, higher income, and the professionals. Psychological factors including cognition of stress and depression was shown to be closely related with suicidal ideation and TMD prevalence. Conclusions : To prevent TMD, it is necessary to provide the systematic oral health education and to develop the combined psychological counseling with treatment program.

Patients often seek consultation with dentists for their temporomandibular disorders (TMD), especially for pain. Acute pains refer to pains that are of short duration. Common acute TMD are arthralgia and local myalgia. Diagnosis should be made based on careful history taking and clinical examination. Most acute TMD are well controlled by education, cognitive awareness training, and conservative treatment. The aggressive and irreversible treatments should not be applied. Acute TMD should be controlled in the early phase so as not to be proceed to chronic pain.
