FASCINATION ABOUT ER:YAG& ER

On root cementum, regarding thermal impact during irradiation, previous studies confirmed only somewhat charred overall look was produced by Er:YAG laser with out h2o coolant [31], whereas evident carbonization was observed with Er,Cr:YSGG laser without h2o coolant [32]. Appropriately, the Er:YAG laser creates less thermogenesis and could be fewer
