Objectives: The purpose of this study was to examine the effects of oral and mental health status on temporomandibular joint disorders (TMDs) and the effects of TMD symptoms on quality of life using data from the 5th 2012 National Health and Nutrition Examination Survey. Methods: A total of 1,154 people were selected as subjects for the study. Temporomandibular joint (TMJ) sounds (672 persons), TMJ pain (227 persons), and TMJ dislocation (255 persons) were the factors studied. The complex sample chi-square test was performed to compare demographic characteristics according to the three groups of TMD symptoms. Complex sample logistic regression analysis was performed to confirm the effect of oral and mental health status on TMDs, and complex sample linear regression analysis was performed to check the effect of TMDs on the quality of life (EQ-5D). Results: After adjusting for demographic characteristics, those without TMJ sound symptoms had lower pain/discomfort (OR: 0.055, CI: -0.095 to -0.016) and anxiety/depression (OR: 0.053, CI: -0.092 to -0.014). Those without TMJ pain had lower pain/discomfort (OR: 0.119, CI: -0.192 to -0.046) and anxiety/depression (OR: 0.071, CI: -0.137 to -0.004). Pain/discomfort (OR: 0.063, CI: -0.125 to -0.001) was lower in those without TMJ dislocation symptoms. After adjusting for mental health status, pain/discomfort (OR: 0.088, CI: -0.161 to -0.014) was found to be lower in those without TMJ pain symptoms (p<0.05). Conclusions: Based on the results of this study, the treatment of TMDs, oral health, and also mental health, is needed to improve the quality of life.

The Temporomandibural joint(TMJ) is one of the most frequently used joint in the body as $1,500{\sim}2,000$ times per day for the activities of chewing, swallowing, talking, yawing and sneezing. The TMJ are formed by condylar process of mandible and mandible fossa of temporal bone, separated by an articular disc. This articular disc divides into two cavities as upper cavity and lower cavity. The gliding movement occurs in the upper cavity of the joint, whereas hinge movement occurs in the lower cavity. The movements that are allowed at the TMJ are opening, closing, protrusion, retraction and lateral movement. A cause of TMJ dysfunction are capsulitis, internal derangement, osteoarthritis, rheumatoid arthritis, infection and inflammation near the joint, trauma on joint, ankylosis, subluxation or dislocation of joint, injury of articular disc, myositis, muscle contracture or spasm, myofascial pain dysfunction syndrome, dyskinesia of masticatory muscles, developmental abnormality, tumor, connective tissue disease, fibrosis, malocclusion, swallowing abnormality, wrong habits such as bite nail or hair, bruxism, psycological stress and Costen syndrome etc. Assessment of TMJ dysfunction consist of interview, observation, functional examination, palpation, reflex test, joint play test, electromyography and radiologic examination and behavioral and psycological assessment etc.

Difficulty in breathing can be very disconcerting to a patient who is conscious yet unable to breath normally. The common causes of acute respiratory distress include hyperventilation, vasodepressor syncope, asthma, heart failure, and hypoglycemia. In most of these situations, the patient does not exhibit respiratory distress unless an underlying medical disorder becomes acutely exacerbated. Examples of this include acute myocardial infarction, anaphylaxis, cerebrovascular accident, hyperglycemia, and hypoglycemia. A major factor that leads to the exacerbation of respiratory disorders is undue stress, either physiologic or psychologic. Psychologic stress in dentistry is the primary factor in the exacerbation of preexisting medical problems. Therefore, the most dental patient should be cared gently as the stress reduction protocol. This is a case report of acute respiratory distress with vasodepressor syncope during alginate impression taking of mandibular teeth in a long-standing temporomandibular joint dislocated 93-years-old pneumonic patient.

Dislocation of the temporomandibular joint (TMJ) occurs when the mandibular condylar head is displaced completely out of the glenoid fossa and cannot be reduced by the patient. The occurrence of bilateral anterior dislocation is the most common. Dislocations can be classified into three types in terms of duration and frequency of dislocation, i.e., acute, chronic and recurrent. There are various treatment modalities for dislocation from conservative try to surgical intervention. The selection for the appropriate modality mainly depends on the types of dislocation as previously stated. The authors report three cases of dislocation with different treatment modalities according to the duration of dislocation. In particular, we tried prosthetic approach instead of surgical intervention in the patient with chronic dislocation.

Management of temporomandibular joint (TMJ) ankylosis is challenging for the oral and maxillofacial surgeon because it involves the mouth opening, dentofacial deformity, diet problem, and quality of life. Although surgical techniques to treat TMJ ankylosis have improved, reankylosis is a persistent problem. The temporalis myofascial flap provides good material for interpositional arthroplasty, because of its good vascular supply, anatomic proximity, and adequate thickness. This case report examines the efficacy of submandibular anchorage to prevent reankylosis by inhibiting flap dislocation.

Arthroscopy is useful to detect early changes in the temporomandibular joint (TMJ). Despite great advances in arthroscopy, many arthroscopic surgeries have now been replaced by arthrocentesis. We propose a simple diagnostic and therapeutic method having operative rigid ultra-thin arthroscopy with 16 gauge needle size combined with arthrocentesis.

Recurrent mandibular dislocation is frequent morbidity of temporomandibular joint relatively. There are many etiologic causes in TMJ disorders but, difficult to find obvious one. Various treatment methods have been utilized for a mandibular dislocation. It is categorized into two groups broadly - nonsurgical or surgical methods. The basic rationale of the surgical method is to allow free movement of the condyle by reducing height of articular eminence or to limit anterior excessive movement of the condyle by increasing height of articular eminence or soft tissue anchoring procedure. In this case, 69 year-old woman was treated by augmentation of the articular eminence with mandibular symphysial bone graft leading to osteosynthesis without difficulty. As a result, favorable postoperative outcome was obtained functionally without any complication or recurrence.

Bell's palsy is an isolated facial paralysis of sudden onset caused by a neuritis of the seventh nerve within the facial canal. It occurs often in the adult man with a history of recent exposure to local cold, such as sleeping next to an open window, or in some cases it occurs after infections of the nasopharynx or masticator spaces. Especially, this neuropathy have linked with the major collagen disorders (diabetes mellitus). A segmental demyelination develops rapidly, with vascultitis in microinfarcts and ischemia to the nerve segment. The authors experienced about the bizarre neurological symptom of Bell's palsy after inferior alveolar nerve block anesthesia and TMJ dislocation in diabetic mellitus. The early and correct consultation with the multiple medical and dental departments was important to prevent the inadequate care & medicolegal problems.

Introduction: In today's society, the rapid and appropriate care of the dental emergency patients is much more important. So, a retrospective study on the characteristics of emergency dental injuries and diseases will be very meaningful. Materials and Methods: This retrospective clinical study was carried by reviewing the radiographic films and emergency chart of 11,493 patients who had visited the emergency room of Hallym Sacred heart Hospital and were treated in the Department of Oral and Maxillofacial Surgery from January 2006 to December 2010. Results: The male to female ratio was 1.9:1. The highest monthly incidence was observed in May (10.4%) and June (8.9%) and the peak age distribution was the first decade (56.0%), followed by the second decade (16.0%). Trauma was the most common cause in dental emergency patients, followed in order by toothache, odontogenic infection, temporomandibular joint (TMJ) disorder and oral hemorrhage. Soft tissue injury was most prevalent in the trauma group, followed by tooth injury and facial bone fractures. In the tooth injury group, tooth fracture (56.7%) showed the highest incidence followed in order by tooth subluxation (18.2%), tooth concussion (16.9%), tooth avulsion (11.5%) and alveolar bone fractures (3.7%). In the facial bone fracture group, mandibular fractures (81.8%) showed the highest incidence followed in order by maxilla fractures (15.7%), nasal bone fractures (9.0%), zygomaticomaxillary complex fractures (5.4%), orbital bone fractures (2.5%). In mandibular bone fractures, the most common location was the symphysis (70.1%), followed in order by the mandibular angle (33.0%), mandibular condyle (22.8%) and mandibular body (13.6%). In the infection group, a submandibular space abscess (46.2%) was most common followed in order by a buccal space abscess (17.4%), canine space abscess (16.9%) and submental space abscess (12.3%). TMJ dislocation (89.3%) showed the highest incidence in the TMJ disorder group, followed by TMJ derangement (10.7%). In the other group, a range of specific symptoms due to post operation complications, trigeminal neuralgia, chemical burns and foreign body aspiration were reported. Conclusion: For the rapid and appropriate care of the dental emergency patients, well-organized system should be presented in oral and maxillofacial surgery. And it is possible under analysis of pattern and the variation of the dental emergency patients.
