DETAILS, FICTION AND ER:YAG& ER

On root cementum, regarding thermal impact all through irradiation, previous experiments confirmed only a little charred visual appeal was produced by Er:YAG laser with out drinking water coolant [31], While apparent carbonization was observed with Er,Cr:YSGG laser without water coolant [32]. Appropriately, the Er:YAG laser makes much less thermoge
