초록

$CO_2$ laser beam was focused a ZnSe lens onto the center of the occlusal surface of extracted lower molars. K-type thermocouple was contacted with the pulp chamber and the changes of temperature in the pulp chamber during and after the laser irradiation were measured as function of the power of laser beam, the time of laser irradiation and thickness of the sample. An empirical formula for temperature effect was derived from the measured data.
