ER:YAG& ER SECRETS

On root cementum, concerning thermal impact during irradiation, preceding scientific studies showed only a little bit charred physical appearance was produced by Er:YAG laser with no h2o coolant [31], Whilst apparent carbonization was observed with Er,Cr:YSGG laser with out h2o coolant [32]. Accordingly, the Er:YAG laser generates less thermogenesi
