Tooth pulp evoked potentials (TPEPs) and subjective evaluation of painful dental stimuli have been recorded in healthy volunteers. The amplitude of TPEPs late components and the subjective rating have been studied in different psychological states, by the expectancy of pain with a placebo and by providing foreknowledge of stimulus timing with self-stimulation. The placebo induced a significant depression of TPEPs and pain sensation. The amplitude of TPEPs evoked by self-delivered stimuli was reduced but the subjective report remained unchanged. These results demonstrate that TPEPs are not a stable correlate of the pain perceived or of the painful input.
在健康志愿者中记录了牙髓诱发电位（TPEPs）以及对牙科疼痛刺激的主观评估。通过使用安慰剂产生疼痛预期以及通过自我刺激提供刺激时间的预先知晓，研究了TPEPs晚期成分的幅度和主观评分在不同心理状态下的情况。安慰剂导致TPEPs和疼痛感觉显著降低。自我给予刺激诱发的TPEPs幅度降低，但主观报告保持不变。这些结果表明，TPEPs并非所感知疼痛或疼痛输入的稳定关联指标。
