CR:YAG CRYSTAL NO FURTHER A MYSTERY

On root cementum, with regard to thermal impact in the course of irradiation, past studies confirmed only slightly charred look was made by Er:YAG laser with no drinking water coolant [31], whereas obvious carbonization was noticed with Er,Cr:YSGG laser with out h2o coolant [32]. Accordingly, the Er:YAG laser creates much less thermogenesis and sho
