The purpose of this study was to examine the influence of the inhibition of the bruxism during sleep on the relationship between the EMG of the masseter and the concentration of the stress hormone in the urine.Twelve subjects were selected in this study. The EMG of the masseter during sleep at night was recorded. Besides this recording, the urine was collected before sleeping and just after the rising. These practices were performed under the following three types of the condition. The first was the condition, which was free from the inhibition of the bruxism. The second was the conndition, which inhibit the bruxism using the appliance. The third was the condition, which was free from the inhibition of the bruxism using the dummy of the appliance. The number of the episode of the EMG burst per hour was computed in each of the three types of the condition. The urine hormone ratio (after rising/before sleep) was also calculated. The four hormones were examined in this study ( dopamine, noradrenaline, adrenaline). In each of the four hormones, the correlation between the number of the episode of the EMG burst and the urine hormone ratio was examined. If the correlation was observed in some kind of the hormone, then the correlation between the EMG and the urine hormone ratio was re-examined in that kind of hormone.Noradrenaline indicated the high correlation between the EMG and the urine hormone ratio. On the contrary, other three kind of hormones indicated low correlation. Noradrenaline indicated high correlation between the EMG and the urine ratio under the two types of the condition, which was free from bruxism. On the contrary, noradrenaline indicated low correlation between the EMG and the urine ratio under the condition, which inhibit the bruxism.

这项研究的目的是检查睡眠期间磨牙抑制对肌肉EMG与尿液中应激激素浓度之间关系的影响。夜间睡眠期间的摩尔人EMG记录了。除了这张录音外，还在睡觉前和崛起之后收集尿液。这些做法是在以下三种情况下进行的。第一个是条件，不受磨牙症的抑制。第二个是缠结，它使用设备抑制磨牙症。第三个是条件，它不受设备虚拟的抑制作用。在条件的三种类型中，计算每小时EMG爆发的发作的数量。还计算了尿激素比（升高/睡眠前）。在这项研究中检查了四种激素（多巴胺，去甲肾上腺素，肾上腺素）。在四种激素中的每一种中，检查了EMG爆发的发作数量与尿激素比率之间的相关性。如果在某种激素中观察到相关性，则以这种激素重新检查EMG与尿激素比之间的相关性。Noradrenaline表明EMG与尿激素比率之间的相关性很高。相反，其他三种激素表明相关性较低。去甲肾上腺素表明在两种类型的情况下，EMG与尿比之间的高相关性，这是不含磨牙症的。相反，去甲肾上腺素表明在这种情况下EMG与尿比率之间的相关性较低，这抑制了磨牙症。
