$CO_2$ 레이저 광의 조사 조건에 따른 치아의 치수강내 온도변화
Temperature change in pulp chamber of teeth by $CO_2$ laser irradiation
초록
CO2 laser beam was focused by a ZnSe lens onto the center of the occlusal surface f extracted lower molars. K-type thermocouple was contacted with the pulp chamber and the changes of temperature in the 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.
