17名正常成年志愿者的牙髓通过一对电极植入牙本质进行电刺激。从头部表面记录的计算机求和反应由两个并发的事件序列组成，其中一个在中线区域最大，另一个在后中央区域的较低部分最大。适当的测试表明，这些波形代表脑牙髓诱发电位。由于牙髓诱发电位代表了与感知有害刺激相关的中枢事件的客观、可量化、非语言伴随物，因此它们可能有助于研究人类急性实验性疼痛。
The pulp of individual teeth of 17 normal adult volunteers was electrically stimulated via pairs of electrodes implanted into dentine. Computer-summated responses recorded from the surface of the head were composed of two concurrent sequences of events, one of which was seen maximally over midline areas and the other over the lower portions of the postcentral regions. Appropriate tests demonstrated that these wave forms represented cerebral tooth pulp-evoked potentials. Because tooth pulp-evoked potentials represent objective, quantifiable, nonverbal concomitants of central events associated with the perception of noxious stimuli, they may prove helpful in investigating acute experimental pain in man.
