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.
