Establishment and clinical application of psychophysical measurement methods related to the tooth contacting perception

本研究旨在建立客观评价牙齿接触知觉的指标体系，并阐明其性质。这是一个重复性很强的系统，由计算机程序控制，避免了实验者的偏差，并且用该系统进行的测量表明，牙齿接触知觉阈值的标准值在20- 70 mN之间。牙齿接触知觉可能取决于牙齿是否有牙髓和咀嚼习惯。

This study aimed to construct the system that assess the tooth contacting perception objectively and to elucidate the property. This is a highly repetitive system avoiding experimenter bias because a computer program controls it. In addition, the measurement using this system suggested that the standard value of the threshold for tooth contacting perception was located in 20-70mN. The tooth contacting perception may depend on whether or not tooth has the pulp and the masticatory habit.
