INDICATORS ON CR:YAG CRYSTAL YOU SHOULD KNOW

On root cementum, regarding thermal affect through irradiation, previous experiments confirmed only a little charred appearance was made by Er:YAG laser without the need of h2o coolant [31], Whilst evident carbonization was noticed with Er,Cr:YSGG laser with out drinking water coolant [32]. Accordingly, the Er:YAG laser creates fewer thermogenesis
