THE BASIC PRINCIPLES OF CR:YAG CRYSTAL

On root cementum, concerning thermal impact all through irradiation, previous reports confirmed only a bit charred physical appearance was produced by Er:YAG laser without h2o coolant [31], whereas clear carbonization was observed with Er,Cr:YSGG laser with no drinking water coolant [32]. Accordingly, the Er:YAG laser produces a lot less thermogene
