THE 2-MINUTE RULE FOR ER:YAG& ER

On root cementum, with regards to thermal impact all through irradiation, previous studies showed only slightly charred physical appearance was made by Er:YAG laser devoid of h2o coolant [31], While apparent carbonization was noticed with Er,Cr:YSGG laser without having water coolant [32]. Accordingly, the Er:YAG laser generates significantly less
