CR:YAG CRYSTAL FUNDAMENTALS EXPLAINED

On root cementum, with regard to thermal impact during irradiation, previous reports showed only slightly charred appearance was made by Er:YAG laser devoid of h2o coolant [31], whereas clear carbonization was observed with Er,Cr:YSGG laser with out water coolant [32]. Accordingly, the Er:YAG laser creates less thermogenesis and should be a lot les
