Providing a method for evaluating the threshold of tooth tactile sensation for the clinical diagnosis of occlusal dysesthesia

开发了一种新的牙齿触觉客观评价系统，该系统利用微型驱动器成功地消除了实验者的偏见。使用该系统，颞下颌紊乱患者的阈值约为53mN，而正常对照组的阈值约为43mN，差异有统计学意义。提示该系统可用于临床检查咬合感觉不良或颞下颌障碍。

A new system to objectively evaluate the tooth tactile sensation was developed, which succeeded to eliminate experimenter bias by using a miniature actuator. Using this system, the threshold for temporomandibular disorder patient was revealed to be approximately 53mN, whereas that for normal control was revealed to be approximately 43mN, with significant difference. It was suggested that this system would be useful for the clinical examination for occlusal dysesthesia or temporomandibular disorders.
