FASCINATION ABOUT ER:YAG& ER

On root cementum, with regard to thermal influence during irradiation, earlier reports confirmed only marginally charred physical appearance was made by Er:YAG laser with no drinking water coolant [31], whereas clear carbonization was observed with Er,Cr:YSGG laser devoid of h2o coolant [32]. Appropriately, the Er:YAG laser produces less thermogene
