To clarify the actual state of awake bruxism in patients with temporomandibular disorders and nocturnal bruxism, we analyzed their masseteric activities in the daytime and nighttime. Total integral value of elctromyographic(EMG) activities of masseter muscles during awake state in the daytime except meal time was relatively small in healthy subjects. The value obtained in the patients with temporomandibular disorders and nocturnal bruxism was relatively large and almost equal to those in the total meal time. The masseteric EMG activities during awake states intermingled among the sleep stages in the nighttime accounted for considerable rate of nocturnal masseteric EMG activities. It was suggested that we should pay attention to muscle activities at awake states in the daytime and awake stages among sleep stages in the nighttime, as well as muscle activities during sleep stages, when we consider influences of bruxism on human organism and life.

为了阐明颞下颌疾病和夜间磨牙症患者清醒磨牙症的实际状态，我们在白天和夜间分析了他们的屠杀活动。在健康受试者中，饮食时间相对较小，但在白天清醒状态下，巨肌肌肉肌肉肌肉的总体积分价值（EMG）活性。颞下颌疾病和夜间磨牙症患者获得的价值相对较大，几乎等于总饮食时间。在夜间睡眠阶段中混合在夜间睡眠阶段中的屠杀EMG活动占了夜间屠杀EMG活动的相当多率。有人建议，当我们考虑磨牙症对人类有机体和生命的影响时，我们应该关注白天在白天在清醒状态下的肌肉活动，并在夜间睡眠阶段以及睡眠阶段醒着阶段。
