A whole night recording of EEG, EMG and EOG of 7 bruxers during sleep with S-EEG equipment is made. Two of them have been evaluated after splint therapy. After analysing the sleep architecture, sleep progress and sleep index, it is found that: (1) S2 period is shorter, REM period is longer and the REM percentage is higher in comparison with the control group; (2) The total teeth grinding period is 213-691 secs and the frequency is 24-70 times per night, the occurrence of teeth grinding is scattered in different sleep stages; (3) The frequency and period of teeth grinding are decreased significantly after splint therapy; and (4) The occurrence of teeth grinding is a kind of functional disturbance of central nervous system rather than. The aroused response or transfer of sleep stages.
使用睡眠脑电图（S-EEG）设备对7名磨牙症患者进行了整夜的脑电图（EEG）、肌电图（EMG）和眼电图（EOG）记录。其中两人在使用牙合板治疗后进行了评估。在分析睡眠结构、睡眠进程和睡眠指数后发现：（1）与对照组相比，慢波睡眠2期（S2）较短，快速眼动期（REM）较长且REM百分比更高；（2）总磨牙时间为213 - 691秒，频率为每晚24 - 70次，磨牙发生在不同睡眠阶段；（3）牙合板治疗后磨牙频率和时间显著降低；（4）磨牙的发生是一种中枢神经系统的功能紊乱，而非睡眠阶段的唤醒反应或转换。
