THE 2-MINUTE RULE FOR ER:YAG& ER

On root cementum, when it comes to thermal affect all through irradiation, former scientific studies showed only somewhat charred visual appearance was produced by Er:YAG laser without having water coolant [31], whereas noticeable carbonization was noticed with Er,Cr:YSGG laser without h2o coolant [32]. Appropriately, the Er:YAG laser makes less th
