THE CR:YAG CRYSTAL DIARIES

On root cementum, with regards to thermal impact in the course of irradiation, earlier studies showed only a bit charred physical appearance was produced by Er:YAG laser with no drinking water coolant [31], whereas noticeable carbonization was noticed with Er,Cr:YSGG laser without water coolant [32]. Appropriately, the Er:YAG laser creates a lot le
