The thresholds to electrical stimulation and the conduction velocities of nerve fibres supplying the pulp of cat canine teeth have been determined. Compound action potentials and the responses of 80 single units were recorded from the inferior alveolar nerve. The properties of 4 types of coronal stimulating electrode were compared. In the single unit studies separate estimates of intradental and extradental conduction velocity of the fibres were obtained by stimulating the pulp in the crown and in the root of the tooth. The units had extradental conduction velocities ranging from 57.7 to 0.9 m . s-1 and therefore included A beta-, A delta- and C-fibres. The thresholds of the units to coronal stimulation ranged from 7 microA, 0.1 ms to 805 microA, 1.0 ms.
已确定了猫犬齿牙髓神经纤维的电刺激阈值和传导速度。从下牙槽神经记录了复合动作电位和80个单纤维单位的反应。比较了4种类型的冠部刺激电极的特性。在单纤维单位研究中，通过刺激牙冠和牙根的牙髓，分别获得了纤维在牙内和牙外的传导速度估计值。这些单位的牙外传导速度范围为57.7至0.9米·秒-1，因此包括Aβ、Aδ和C纤维。这些单位对冠部刺激的阈值范围为7微安、0.1毫秒至805微安、1.0毫秒。
