NOT KNOWN FACTS ABOUT ER:YAG& ER

On root cementum, regarding thermal affect through irradiation, earlier scientific studies showed only somewhat charred appearance was made by Er:YAG laser with no drinking water coolant [31], whereas obvious carbonization was observed with Er,Cr:YSGG laser with no h2o coolant [32]. Appropriately, the Er:YAG laser makes a lot less thermogenesis and
