NOT KNOWN FACTS ABOUT ER:YAG& ER

On root cementum, concerning thermal impact all through irradiation, earlier studies showed only a little bit charred visual appeal was made by Er:YAG laser without having drinking water coolant [31], whereas obvious carbonization was observed with Er,Cr:YSGG laser without h2o coolant [32]. Accordingly, the Er:YAG laser generates less thermogenesis
