Abstract
The effect of mechanical vibratory stimulation on the human tooth pain threshold has been studied in 4 healthy naïve subjects. Vibration at 10 and 100 Hz was applied to a maxillary incisor and the electrical pain threshold was measured in an adjacent tooth. During the conditioning stimulation the pain threshold increased 1.2-1.8 times the unconditioned values. The present study indicates that mechanical vibratory stimulation applied to human teeth elevates the pain threshold in adjacent teeth.
摘要
在4名健康的未受过刺激的受试者中，研究了机械振动刺激对人类牙齿疼痛阈值的影响。对上颌切牙施加10赫兹和100赫兹的振动，并测量相邻牙齿的电疼痛阈值。在条件刺激期间，疼痛阈值增加到非条件值的1.2至1.8倍。本研究表明，施加于人类牙齿的机械振动刺激会提高相邻牙齿的疼痛阈值。
