FASCINATION ABOUT ER:YAG& ER

On root cementum, regarding thermal affect in the course of irradiation, prior experiments showed only a bit charred visual appeal was made by Er:YAG laser without h2o coolant [31], whereas obvious carbonization was observed with Er,Cr:YSGG laser with out water coolant [32]. Appropriately, the Er:YAG laser generates less thermogenesis and should be
