A clinical and radiographic evaluation of using Erbium, Chromium, Scandium, Gallium and Garnet (Er,Cr:YSGG) laser in recipient site bio-modification and de-epithelialized connective tissue graft harvesting compared to conventional scalpel surgical technique in the treatment of class I and II Miller gingival recession.
Twenty four patients suffering from isolated Class I and II Miller gingival recession defects in anterior esthetic region were enrolled in this study. They were randomly assigned into three groups; de-epithelialized connective tissue graft harvesting technique or; conditioning the exposed root surfaces with Er,Cr:YSGG laser before connective tissue coverage using scalpel blade harvested de-epithelialized connective tissue graft harvesting technique, or; conditioning the exposed root surfaces with the Er,Cr:YSGG laser before Er,Cr:YSGG laser harvested connective tissue using de-epithelialized technique. Clinical and radiographic parameters were recorded at baseline and at 3, 6 and 9 months postoperatively.
