title: Quantitative relation between the intensity of tooth pulp stimulation and the magnitude of jaw opening reflex in the rat.
abstract: The stimulus-response relation in the jaw opening reflex evoked by tooth pulp stimulation, which is considered as a "pain index", follows the power function with an exponent of about six over a range of lower stimulus intensities.
