10 outpatients with bruxism were investigated by polygraphic recordings during night sleep. Electromyogram, electrooculogram and electroencephalogram derivations were used to evaluate the activities of masseter muscle and the different stages of sleep. The results of the bruxist group were compared to those of an age-matched control group. The amount and the length of pressing and grinding jaw movements were correlated with the sleep period time as well as with the different sleep stages. In comparison to the control group, a significant difference of muscle activity longer than 5 s was found, but there was no difference regarding activities of 3-5 s duration. The highest level of activity was found in sleep stage two and during awakening times. No difference was seen with regard to percentages of the sleep stages.
对10名磨牙症门诊患者进行了夜间睡眠多导记录研究。采用肌电图、眼电图和脑电图记录来评估咬肌活动及不同睡眠阶段。将磨牙症组的结果与年龄匹配的对照组进行比较。咬牙和磨牙下颌运动的次数及持续时间与睡眠时间以及不同睡眠阶段相关。与对照组相比，发现肌肉活动超过5秒有显著差异，但3 - 5秒时长的活动无差异。活动水平最高出现在睡眠第二阶段和觉醒期。睡眠阶段的百分比未见差异。
