This study was composed of 3 experiments. In the first study, dentists, dental hygienists, and dental students were asked to answer questionnaire concerning the relationship between tooth pain and bruxism. Almost all dentists answered that tooth pain can be derived from bruxism, but some of them do not inform or explain to their patients. There were quite a few dentists that do not have distinctive category for diagnosing bruxism. In the second part of the experiment, healthy cohorts were recruited to have clenching-induced tooth pain. The condition was reported subjectively by questionnaire, and functional status of MKG/EMG was monitored using K7 evaluation system(R). Although no tooth pain was induced by clenching, some cohorts felt tightening pain in the muscles. In the third experiment, muscle fatigue was monitored by MR imaging. The T2 value rose significantly after clenching. It was suggested that patients with bruxism might have higher T2 value because of their chronic muscle fatigue. Our final goal was to make the guidelines for diagnosing and treating bruxism. This was achieved by publishing two text books regarding bruxism.

本研究由3个实验组成。在第一项研究中，牙医、牙科保健员和牙科学生被要求回答有关牙痛与磨牙症之间关系的问卷。几乎所有的牙医都回答说牙痛可以来自磨牙症，但他们中的一些人没有告诉或解释给他们的病人。有相当多的牙医没有明确的分类来诊断磨牙症。在实验的第二部分中，健康的队列被招募来进行咬紧引起的牙痛。通过问卷主观报告病情，并使用K7评估系统（R）监测MKG/EMG的功能状态。虽然咬紧牙关不会引起牙齿疼痛，但有些人感到肌肉收紧疼痛。在第三个实验中，通过MR成像监测肌肉疲劳。T2值在紧握后显著升高。提示磨牙症患者T2值增高可能与慢性肌肉疲劳有关。我们的最终目标是制定诊断和治疗磨牙症的指南。这是通过出版两本关于磨牙症的教科书实现的。
