Objectives: This study aimed to evaluate the effects of occlusion patterns using the T-scan III® 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® 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 (±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®system,andthemeanocclusiontimewas0.42(±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.
