ER:YAG& ER SECRETS

On root cementum, with regard to thermal impact through irradiation, prior reports confirmed only a little bit charred look was made by Er:YAG laser with no water coolant [31], Whilst obvious carbonization was observed with Er,Cr:YSGG laser without water coolant [32]. Appropriately, the Er:YAG laser produces much less thermogenesis and should be mu
