CR:YAG CRYSTAL NO FURTHER A MYSTERY

On root cementum, regarding thermal impact in the course of irradiation, prior studies confirmed only a bit charred visual appearance was made by Er:YAG laser devoid of drinking water coolant [31], Whilst evident carbonization was noticed with Er,Cr:YSGG laser with no h2o coolant [32]. Appropriately, the Er:YAG laser provides considerably less ther
