This study aimed at identifying the factors that influence the incidence of temporomandibular disorders (TMD) in a Japanese working population. Subjects comprised of 4771 employees from the four Japanese companies. The subjects were assessed using a questionnaire that covered TMD, contributing factors (using a 5-point numeric rating scale) and the time of visual display terminal (VDT) work. TMD were measured from 4 items on the questionnaire (using a 5-point numeric rating scale, 0-4). The TMD group constituted 7.7% of the subjects. Logistic regression analyses indicated that female gender, one side chewing, excessive tension, tiredness, body pain, and the disappearance of the mandibular freeway space were significant contributors to the manifestation of TMD. The VDT work time was significantly longer in the TMD group than in the non-TMD group.

本研究旨在确定影响日本工作人群颞下颌关节紊乱病（TMD）发病率的因素。受试者包括来自四家日本公司的4771名员工。受试者进行了评估，使用问卷调查，包括TMD，影响因素（使用5点数字评分量表）和时间的视觉显示终端（VDT）的工作。TMD从问卷上的4个项目中测量（使用5点数字评分量表，0-4）。 TMD组占受试者的7.7%。Logistic回归分析显示，女性、单侧咀嚼、过度紧张、疲劳、躯体疼痛、下颌高速公路间隙消失是TMD的显著影响因素。TMD组VDT作业时间明显长于非TMD组。
