THE BEST SIDE OF CR:YAG CRYSTAL

On root cementum, in terms of thermal impact during irradiation, previous scientific studies showed only a bit charred visual appeal was produced by Er:YAG laser without having water coolant [31], whereas apparent carbonization was observed with Er,Cr:YSGG laser without the need of h2o coolant [32]. Appropriately, the Er:YAG laser provides fewer th
