Study Overview
Brief Summary
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.
Detailed Description
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.

- Intervention Model
- Parallel
- Primary Purpose
- Treatment
- Masking
- Single (Outcomes Assessor)
Masking Description
Masking of investigator and participants was not applicable due to surgical procedure and use of laser either for root surface bio-modification or during connective tissue harvesting. The blinded outcome assessor performed the clinical measurements at each selected defect site during the study period. She was not involved in any other part of the study protocol.
