Abstract

This study examined both TMJ and normal groups for any changes in the masseteric silent period with variation of the subjects' occlusal force. An analog meter was used to give each subject feedback on how hard the teeth were clenched together. Five silent periods were elicited at each of the four levels of occlusal force from 40% to 100% of maximum force. Results showed a small decrease in silent period duration for both groups when occlusal force was increased.

摘要

本研究检查了颞下颌关节（TMJ）组和正常组，观察随着受试者咬合力变化，咬肌静息期是否有任何改变。使用模拟仪表向每位受试者反馈牙齿咬合的用力程度。在40%至100%最大咬合力的四个咬合力水平上，每个水平均诱发五次静息期。结果显示，两组的静息期时长在咬合力增加时均有小幅缩短。
