Changes in pulp temperature during thermostimulation of human teeth by a simple electrically controlled thermode.

A simple electrically controlled thermode is described that was used in psychophysical experiments on thermoperception from teeth in human subjects. The time course of the intrapulpal temperature changes during a 60 s cooling or heating procedure was measured in in vitro experiments in which the temperature exchange between tooth and surrounding tissue, present in the psychophysical experiments, was stimulated.
