NEW STEP BY STEP MAP FOR ER:YAG& ER

On root cementum, concerning thermal impact throughout irradiation, previous scientific studies showed only somewhat charred physical appearance was made by Er:YAG laser devoid of water coolant [31], Whilst clear carbonization was observed with Er,Cr:YSGG laser with no drinking water coolant [32]. Accordingly, the Er:YAG laser generates less thermo
