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.

这项研究旨在确定日本劳动人群中影响颞下颌疾病（TMD）发生率的因素。受试者由四家日本公司的4771名员工组成。使用涵盖TMD的问卷，促成因素（使用5点数字评级量表）和视觉显示终端（VDT）工作时间来评估受试者。从问卷上的4个项目（使用5点数字评级量表，0-4）测量TMD。 TMD组占受试者的7.7％。逻辑回归分析表明，女性性别，一侧咀嚼，过度张力，疲倦，身体疼痛以及下颌高速公路空间的消失是TMD表现的重要原因。 TMD组的VDT工作时间明显长于非TMD组。
