CR:YAG CRYSTAL FUNDAMENTALS EXPLAINED

On root cementum, in terms of thermal impact in the course of irradiation, preceding scientific tests showed only slightly charred visual appearance was made by Er:YAG laser with no drinking water coolant [31], whereas clear carbonization was observed with Er,Cr:YSGG laser with no h2o coolant [32]. Accordingly, the Er:YAG laser produces less thermo
