CR:YAG CRYSTAL FUNDAMENTALS EXPLAINED

On root cementum, concerning thermal impact through irradiation, former reports confirmed only slightly charred physical appearance was made by Er:YAG laser without having water coolant [31], whereas clear carbonization was observed with Er,Cr:YSGG laser with no h2o coolant [32]. Appropriately, the Er:YAG laser generates a lot less thermogenesis an
