FASCINATION ABOUT ER:YAG& ER

On root cementum, in terms of thermal affect during irradiation, preceding studies showed only marginally charred appearance was made by Er:YAG laser without water coolant [31], Whilst evident carbonization was noticed with Er,Cr:YSGG laser without the need of h2o coolant [32]. Accordingly, the Er:YAG laser provides fewer thermogenesis and will be
