Abstract

The effects of vibrotactile stimulation on dental pain thresholds were studied in 6 healthy human volunteers. Mechanoreceptive afferents were activated with conditioning sinusoidal vibration at 240 and 100 Hz. Significant dental pain threshold elevations were observed only when the conditioning stimulus was applied at high intensity ipsilaterally to the tested tooth. The present study suggests that the dental pain threshold elevation during high-frequency vibratory stimulation is based on the total number of impulses generated in mechanoreceptive afferents.

摘要

在6名健康人类志愿者中研究了振动触觉刺激对牙齿疼痛阈值的影响。用240赫兹和100赫兹的正弦振动作为条件刺激来激活机械感受器传入神经。仅当在同侧以高强度对测试牙齿施加条件刺激时，才观察到牙齿疼痛阈值显著升高。本研究表明，高频振动刺激期间牙齿疼痛阈值的升高是基于机械感受器传入神经中产生的冲动总数。
