THE BASIC PRINCIPLES OF CR:YAG CRYSTAL

On root cementum, regarding thermal influence throughout irradiation, earlier research showed only a bit charred physical appearance was produced by Er:YAG laser devoid of h2o coolant [31], Whilst noticeable carbonization was observed with Er,Cr:YSGG laser without h2o coolant [32]. Appropriately, the Er:YAG laser makes significantly less thermogene
