Purpose: This study is intended to survey male and female university students to see if there is correlation between temporomandibular disorder and oral habits known to cause temporomandibular disorder. Methods: A survey was conducted to 400 male and female university students attending two universities located in Daegu Metropolitan City and Gyeongsangbuk-do to examine if there is correlation between oral habits and temporomandibular disorder. Among total 400 questionnaire sheets, 334 (83.5%) sheets were used for final analysis except for those unreliably answered or containing error. Results: Female students showed a higher prevalence rate of temporomandibular joint pain than male students, and those having the habit of resting jaw on hand indicated a higher prevalence rate of temporomandibular joint pain, temporomandibular joint clicking, or trismus than normal students not having it. Also, those having the habit of tooth clenching showed a significantly higher prevalence rate of temporomandibular joint pain or temporomandibular joint clicking than normal students not having it. Conclusion: It can be concluded that the habit of resting jaw on hand is closely related with temporomandibular disorder like temporomandibular joint pain, temporomandibular joint clicking, or trismus, and the habit of tooth clenching is significantly correlated with such symptoms as temporomandibular joint pain and temporomandibular joint clicking.

Purpose: The study is to discover the relationship between malocclusion, which is known to cause temporomandibular disorder, and temporomandibular disorder and is aimed at college students who have retained their natural teeth. Methods: The study was aimed at 500 college students at two colleges located in Gyeongsangbuk-do and Daegu metropolitan city and survey research was conducted in order to discover any relationship between malocclusion and temporomandibular disorder. After excluding copies with insincere answers or errors out of the 500 copies of the questionnaire, the study used a total of 435 copies (87%) for research and analysis. Results: Females showed a prevalence of temporomandibular joint clicking and temporomandibular joint pain, and students who had crowding showed a high prevalence of temporomandibular joint pain, temporomandibular joint clicking, and trismus. Students whose occlusal condition was not good demonstrated a high prevalence of temporomandibular joint pain, temporomandibular joint clicking, and trismus. Students who had maxillary protrusion showed a prevalence of temporomandibular joint clicking and trimus, whereas students who had mandibular protrusion showed a high prevalence of temporomandibular joint clicking. Conclusion: Students whose dental condition was crowding and students whose occlusal condition was not good exhibited a high prevalence of three types of symptoms of temporomandibular disorder. Meanwhile student who had maxillary protrusion showed a high prevalence of temporomandibular joint clicking and trismus, while students who had mandibular protrusion showed a prevalence of temporomandibular joint clicking.

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.

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.

Objectives: The aim of this study was to investigate the association between self-esteem and temporomandibular disorder among high school students. Methods: A self-reported questionnaire was completed by 584 high school students in Gyeongnam. The questionnaire consisted of socio-demographic profile, anxiety, self-esteem, oral parafunctional habits, and temporomanibular disorder. Data were analyzed using SPSS 19.0 program. Results: In univariate analysis, there were significant differences between self-esteem and temporomandibular disorder(p<0.05). The self-esteem was negatively correlated with parafunctional habits(r=-0.253, p<0.001) and temporomandibular disorder(r=-0.221, p<0.001). In multivariate analysis, self-esteem was significantly associated with temporomandibular disorder(${\beta}=-0.119$, p=0.025) after adjusting for socio-demographic characteristics and anxiety. Conclusions: The self-esteem negatively influenced on temporomandibular disorder in the high school students.

Temporomandibular joint disorder(TMJD) was mainly characterized with joint pain, motion limitation, joint sound, resulted from pathologic conditions in temporomandibular joint and around tissue. As temporomandibular joint is one of decisive factors determining the occlusion, disorders in temporomandibular joint may cause the occlusal changes. The causes of occlusal changes related with TMJD can be classified into 2 categories; (1) those related to progression of disorder, 2) those related to treatment of the disorder. The clinical manifestation of occlusal changes depend on their causes and affected site. Therefore, whenever possible, treatment should be directed to the relief of the underlying causes, However, it is not always possible to relieve the underlying conditions. Moreover, some occlusal changes may remain irreversible even after the considerable improvement in clinical symptoms. Regarding the treatment of the permanent occlusal changes, it has been reported that the extensive occlusal treatment including occlusal adjustment, prosthodontic treatment, orthodontic treatment should be applied. Here, we present with a case report of occlusal change caused by the progressive temporomandibular joint disorder, together with introducing the intermaxillary traction appliance as the possible treatment option.

The masticatory muscle disorder is the most common problem that patients with temporomandibular disorder often complain. For such complaints, treatment is directed towards reducing hyperactivity of muscles or effects of the central nervous system. However, if nonspecific occlusal change or pain persists, it is necessary to consider that muscle weakness might be the cause of the persistence of temporomandibular disorder. Stabilization of occlusion and improvement of the pain symptoms were achieved in both cases through the chewing gum exercise. This exercise may enable masticatory movements done in normal function by using muscle engram and achieve reinforcement of the masticatory muscles with balanced, simultaneous contacts of the teeth. In addition, it may be a viable method for treating temporomandibular disorders that do not respond well to conventional mandibular stabilization therapies.
