旨在
旨在测试基于力的磨牙症检测系统（夹板内力检测器[ISFD]）的可靠性和实用性，用于在家庭环境中睡眠的人类受试者中进行牙齿与夹板的强力接触的多次夜间记录。
方法
磨牙型力，即，在12名受试者（6名磨牙者和6名对照者）的家庭环境中，用该系统记录了5个晚上牙齿与夹板的有力接触;还对其中1名受试者进行了基于实验室的夜间多导睡眠图（NPSG）研究。
结果
所有12名受试者都能够在夜间使用该器械，没有实质性困难。磨牙组的磨牙事件持续时间明显长于对照组（27秒/小时对7.4秒/小时，P <0.01）。对1名受试者进行的NPSG研究显示，当咬肌肌电图（EMG）用作“金标准”时，ISFD的灵敏度为0.89。ISFD检测到的事件持续时间与EMG之间的相关系数也为0.89。
结论
这些结果表明，ISFD是一个系统，可以很容易地使用的主题，并有一个合理的可靠性磨牙症检测反映在有力的牙齿夹板接触在睡眠期间。
AIMS
To test the reliability and utility of a force-based bruxism detection system (Intra-Splint Force Detector [ISFD]) for multiple night recordings of forceful tooth-to-splint contacts in sleeping human subjects in their home environment.
METHODS
Bruxism-type forces, i.e., forceful tooth-to-splint contacts, during the night were recorded with this system in 12 subjects (6 bruxers and 6 controls) for 5 nights in their home environment; a laboratory-based nocturnal polysomnogram (NPSG) study was also performed on 1 of these subjects.
RESULTS
All 12 subjects were able to use the device without substantial difficulty on a nightly basis. The bruxer group exhibited bruxism events of significantly longer duration than the control group (27 seconds/hour versus 7.4 seconds/hour, P < .01). A NPSG study performed on 1 subject revealed that, when the masseter muscle electromyogram (EMG) was used as a "gold standard," the ISFD had a sensitivity of 0.89. The correlation coefficient between the duration of events detected by the ISFD and the EMG was also 0.89.
CONCLUSION
These results suggest that the ISFD is a system that can be used easily by the subjects and that has a reasonable reliability for bruxism detection as reflected in forceful tooth-to-splint contacts during sleep.
