[Temperature profile in the enamel during cold tests].
The temperatures on the surface of human teeth during pulp vitality tests with frigen and carbon dioxide snow were recorded in an in vitro study. Frigen spray caused particularly rapid changes in temperature. The lowest temperature (-52 degrees C) was measured with CO2-snow (with a pressure of 9.81 N against the tooth surface). To obtain higher temperatures at lower rates of change, the use of a thin latex fingerstall proved to be effective.
