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.

Purpose: The aim of this study was to investigate the effects of academic stress and self-control ability on temporomandibular disorder (TMD) of adolescents. Methods: Participants were 1,112 teenagers who were 1st grade students of middle and high school. After checking their academic stress and self-control ability through a self-administrated questionnaire, the students were examined their TMD by two trained dentists. We drew a comparison the level of their academic stress and self-control ability between the students with and without TMD. We divided them to four groups according to the level of academic stress and self-control. And we checked prevalence of TMD in each level. Results: The group of students with TMD was higher academic stress score level than the students without TMD (p<0.05). And they had lower self-control score level than the students without TMD (p<0.05). Even if they were under the same academic stress, the group of students with higher self-control score was less TMD prevalence than the students with lower score. Conclusions: Academic stress makes adolescents to increase TMD and high ability of self-control makes them to decrease it. And these tendencies are seemed to have a great influence on young male student.

Purpose: The purpose of this study was to analyze the extent of awareness and understanding of college students on temporomandibular disorder (TMD) and to search for avenues for raising public awareness and improving knowledge about TMD. Methods: One thousand and one hundred and twenty one college students in Gyeonggi-do completed a questionnaire related to awareness, experience and knowledge of TMD and collected data were analyzed by Pearson's chi-squared test. Results: Women were more significantly aware of the terms, 'TMD' (p<0.001) and 'jaw joint disease' (p<0.001) than men. Third graders were more significantly aware of the terms, 'TMD' (p<0.001) and 'jaw joint disease' (p<0.001) than any other graders. Third graders the most frequently chose to visit department of dentistry for the treatment of TMD among three graders (p<0.001). Women more frequently chose to visit department of dentistry for the treatment of TMD than men (p<0.001). Health field subjects were more significantly aware of the terms, 'TMD' (p<0.001) and 'jaw joint disease' (p<0.001) than non health field subjects. Having more frequently visited department of dentistry for the treatment of TMD than non health field subjects (p<0.001), health field subjects more frequently chose to visit department of dentistry for the treatment of TMD in the future (p<0.001). Conclusions: The level of awareness and knowledge of TMD was higher in women college students, health field subjects and third graders than men college students, non health field subjects and the rest of two graders, respectively. The higher the level of experience and education of the subject, the more aware the subject was of TMD. Therefore publicity activities and education through various routes are required to raise public awareness and knowledge of TMD. In addition, it is necessary to inform general public of the dentistry specialized for the accurate diagnosis and standardized treatment of TMD.

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.

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.

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.

Objectives: This study aimed to evaluate the effects of occlusion patterns using the T-scan $III^{(R)}$ system and oral parafunctional behaviors on temporomandibular joint disorder (TMD) in female college students. Methods: A questionnaire survey assessed TMD symptoms and oral behavioral checklist (OBC) scores in 120 female college students in their early twenties. Occlusion was evaluated using the T-scan $III^{(R)}$ system. Logistic regression analysis was performed to investigate the relationship between occlusion and OBC scores based on patients' symptoms of TMD and to determine whether OBC scores were a predictor of TMD. Results: A total of 101 participants with an average age of 22 (${\pm}2.17$) years were included in the analysis. The reported symptoms of TMD were categorized as moderate (28.8%), slight (27.7%), severe (25.7%), and asymptomatic (17.8%). Occlusion was analyzed using the T-scan $III^{(R)}$ system, and the mean occlusion time was 0.42(${\pm}0.5$) seconds. The results of logistic regression analysis showed that the group that would 'clench or grind teeth' during sleep showed an odds ratio for TMD that was 8.9 times higher than that in the group without this behavior. The group that would 'hold, tighten, or tense muscles without clenching' while awake showed an odds ratio for TMD that was 21.3 times higher than that in the group without this behavior. Conclusions: We confirmed that oral parafunctional behavior affects TMD. Therefore, we would like to continue studying the diagnosis and treatment of TMD by evaluating occlusion patterns and related OBC scores.
