This study was to investigate the relation between maxillofacial trauma experience and temporomandibular disorder prevalence with a view to helping prevent and cure temporomandibular dysfunctions by conducting a questionnaire survey with 370 students attending C Health Care College located in Ulsan Metropolis. Data collected underwent an analysis using SPSS program, resulting in the following:1. As for TMJ(temporomandibular joint) clicking prevalence rate, with 25.7% of male students and 22.7% of female students answering positively, the former showed higher rate of temporomandibular joint clicking (p<0.01), while no significant difference was identified depending on school years. 2. In terms of temporomandibular pain prevalence rates, females were found to have been more affected than male students. 3. When it comes to trismus prevalence rates, 10.8% of female students and 7.0% of male students responded they had experienced the dysfunction and female students showed slightly higher rate of trismus prevalence. 4. 6.5% of males and 4.3% of female students responded they had got treatment experience resulting from temporomandibular disorders, indicating that more male students had gone through treatment for temporomandibular disorders(p<0.05). 5. Male students showed higher experience rate of maxillofacial trauma(p<0.01), mostly due to falling or tumbling down, followed by exercises and etc. 6. The relation between maxillofacial trauma and temporomandibular disorders showed statistically significant relation between maxillofacial trauma and TMJ(temporomandibular joint) clicking (p<0.01).
