Several studies have demonstrated the relationship between temporomandibular disorder (TMD) and emotional stress. Nonetheless, few surveys have examined the relationship between type A behavior patterns and TMD. The aim of this study was to clarify the relationships among TMD, type A behavior patterns, bruxism, and emotional stress in Japanese undergraduate students. This study was undertaken in Nayoro City, Japan, in 2015, among students of Nayoro City University. The survey was conducted through an anonymous, self-administered, multiple-choice questionnaire. Information was gathered on items evaluating the extent of TMD symptoms, bruxism, type A behavior patterns, and proneness and sensitivity to emotional stress. The questionnaire recovery rate was 31.8% (175/551). There was a high likelihood of TMD in 16.1% of respondents, which is comparable to the findings of previous surveys on Japanese high school students. In keeping with previous studies, we confirmed significant relationships between TMD and both emotional stress and bruxism. A weak but statistically significant association was found between TMD and type A behavior patterns. We propose that TMD may be one of the diseases related to the type A behavior pattern.
多项研究已证实颞下颌关节紊乱症（TMD）与情绪压力之间的关系。尽管如此，很少有调查研究过A型行为模式与TMD之间的关系。本研究的目的是阐明日本大学生中TMD、A型行为模式、磨牙症和情绪压力之间的关系。本研究于2015年在日本名寄市对名寄市立大学的学生进行。调查通过匿名的自填式多项选择题问卷进行。收集了关于评估TMD症状程度、磨牙症、A型行为模式以及对情绪压力的倾向和敏感性等项目的信息。问卷回收率为31.8%（175/551）。16.1%的受访者有患TMD的高可能性，这与之前对日本高中生的调查结果相当。与之前的研究一致，我们证实了TMD与情绪压力和磨牙症之间存在显著关系。在TMD与A型行为模式之间发现了一种微弱但具有统计学意义的关联。我们认为TMD可能是与A型行为模式相关的疾病之一。
