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.
