  • Purpose: The purpose of this study was to investigate the factors contributing to temporomandibular joint disorder symptoms. Methods: The survey was conducted from May 1 to June 10 2017 against college students(120 males and 123 females) in Daejeon and Gangwon who understood the purpose of this study and agreed to participate. Results: First, The most frequent symptom of temporomandibular joint disorders is noises from the joint (male 45%, female 61.8%), followed by headache or neck pain (male 25.8%, female 52.8%). There was shown a significant difference by gender in all items except for jaw dropping, poor alignment of teeth and trauma(p<0.05). Second, Looking into the correlation between stress and subjective symptoms of Temporomandibular joint disorders, The stress of Temporomandibular joint disorders showed more significant relation with realistic issues such as academic task, economic burden (e.g., treatment cost), future career, and life values rather than aspect of social relationship(p<0.01). Conclusion: As a result of analyzing variables to understand the influence of stress on temporomandibular joint disorders, the accumulated number of bad habits, stress and temporomandibular joint disorders showed a significantly positive correlation with one another (p<0.05). In other words, the higher the stress level the severe the temporomandibular joint disorders; the more the bad habits the severe the temporomandibular joint disorders;

  • Objectives: The purpose of this study is to identify the perceived symptoms of oral and temporomandibular joint disorders in adults and to analyze the factors affecting subjective symptoms of temporomandibular joint disorders. Methods: 249 adults over 20 years old who had subjective symptoms of temporomandibular joint disorders were surveyed and analyzed. Independent t-test and ANOVA test were used to examine the relationship between oral habits and temporomandibular joint disorder according to general characteristics. $Scheff{\acute{e}}$ test was used for post-hoc analysis. Multiple regression analysis was conducted to examine the factors affecting oral habits and temporomandibular joint disorder. Results: First, the factors affecting oral and habitual behaviors were married (p<0.05) and monthly income between 1 million~1.9 million won (p<0.001), higher temporomandibular joint disorder (p<0.01) And the degree of habit was increased. Second, the factors affecting temporomandibular joint disorder were increased in occupation (p<0.05) and the degree of oral habit (p<0.01). Conclusions: In conclusion, it was confirmed that oral habit influences temporomandibular joint disorder. Especially, it is suggested that prevention and promotion of temporomandibular joint disorder are needed to recognize the removal of oral habits.

  • 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).

  • Objectives. Temporomandibular joint disorders (TMD) are often associated with aural manifestations. However, it is not clear whether aural fullness could be induced by TMD. The purpose was to investigate the TMD and effectiveness of TMD treatments in patients with mainly or exclusively aural fullness complaint. Methods. One hundred and twelve patients, who had aural fullness as the main or sole complaint, presented to the Otolaryngology Department, PLA Army General Hospital, Beijing, China, between January 2010 and January 2015. Patients' medical history indicated that they had previously been diagnosed and treated for otitis media or sensorineural hearing loss but without positive results. Patients were subjected to pure tone audiometry and acoustic immittance screening using GSI-61 clinical audiometer and GSI TympStar middle ear analyzer respectively. Patients were examined by questionnaire, X-ray and/or computed tomography scan of temporomandibular joint. TMD was categorized according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Patients were then treated for TMD. Results. All the patients showed normal eardrum and type A tympanogram. The patients of 60.7% (68/112) were classified as group I TMD disorders (muscle disorders), 34.8% (39/112) were group II (disc displacements), and 4.5% (5/112) were group III (arthralgia, osteoarthritis, and osteoarthrosis). Aural fullness was completely resolved or significantly improved in 67 and 34 patients respectively following treatments aimed at improving TMD, with a combined effectiveness of 90.2% (101/112). TMD treatments are especially effective (94.1%) in group I TMD. Conclusion. TMD as a potential cause of aural fullness should be considered in otolaryngology practice.

  • The term temporomandibular disorders is used to describe a group of conditions that involve the temporomandibular joint, masticatory muscles, and associated structures. Many modalities have been proposed for treating temporomandibular disorders, including medication, physical therapy, occlusal stabilization splints with or without manual repositioning, surgery, and arthrocentesis. Temporomandibular disorders are treated in a step-wise manner. Initially, conservative treatment is used. Depending on the response, more aggressive interventions may be necessary. This usually takes the form of arthrocentesis. Arthrocentesis is used in the treatment of not only acute, closed, and locked TMJs but also various other temporomandibular disorders. Recently, the intra-articular injection of sodium hyaluronate after arthrocentesis was shown to have long-term palliative effects on TMJ symptoms. Synovial fluid consists of plasma and glycosaminoglycan, including hyaluronic acid derived from synovial cells. Sodium hyaluronate, the sodium salt of hyaluronic acid, is a high-molecular-weight polysaccharide and a major component of synovial fluid. This highly viscous substance has analgesic properties, lubricant effects, and anti-inflammatory actions; it causes cartilage formation and plays a role in the nutrition of avascular parts of the disc and condylar cartilage. We conclude that the intra-articular injection of sodium hyaluronate is effective for treating temporomandibular disorders.

  • Temporomandibular disorders typically present findings of limited or asymmetric patterns of jaw opening and joint sounds usually described as clicking, popping, grating, or crepitus. Recently, patients with temporomandibular disorders have received an increasingly aggressive treatment with a greater emphasis on surgical and dental reconstruction. Scientific studies have not clearly identified the specific causes of the temporomandibular disorders and therefore some of the treatments are empiric, without a firm scientific foundation. We carried out a study on the patients of pain clinic OPD and concluded that the causes of the temporomandibular joint(TMJ) pain are the prolonged contraction of the muscles of mastication, especially the masseter muscle. Therefore, the spasmolytic treatment of masseter muscle would be a better treatment for TMJ syndrome rather than the surgical and dental reconstruction.

  • Occlusion may change spontaneously but dental treatment or trauma in the patients with temporomandibular disorders (TMDs) may also alter occlusion. This report presents three cases displaying occlusal changes. Review of literature emphasizes the significance of TMD treatment. Conservative treatment modalities such as counseling, medication, physical therapy and splint therapy may be selected as initial treatment options. Irreversible or invasive treatment, such as orthodontic, prosthodontic, and occlusal adjustment should not be attempted early. In case there is no response to conservative treatment, joint injection, muscle injection, arthrocentesis or arthroscopic surgery might be performed.

  • 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.

  • 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.

  • 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.
