Single shock electrical stimuli were applied to 8 cat canine teeth before and during electro-acupuncture. Strength-duration curves were constructed for the thresholds using the jaw depressor reflex as the indication of threshold. Electro-acupuncture raised the rheobase voltages slightly more than 2V in most instances. As pulp nerves are known to mediate painful sensations only, jaw depressor thresholds and pain thresholds are functionally equal. Electro-acupuncture had a small but measurable effect. The neurophysiological mechanisms of the threshold elevations are obscure. © 1978.
