CR:YAG CRYSTAL FUNDAMENTALS EXPLAINED

On root cementum, in terms of thermal affect all through irradiation, earlier reports confirmed only marginally charred physical appearance was made by Er:YAG laser without h2o coolant [31], whereas obvious carbonization was observed with Er,Cr:YSGG laser with out drinking water coolant [32]. Accordingly, the Er:YAG laser generates less thermogenes
