- Registration Number
- NCT03200392
- Lead Sponsor
- Misr International University
- 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.

- Primary Outcome Measures
Name Time Method Change in Recession depth baseline-3-6-9 months measured from the gingival margin to the cemento-enamel junction at the mid-buccal aspect of the tooth using William's graduated periodontal probe to the nearest mm
- Secondary Outcome Measures
Name Time Method Height of keratinized tissue width baseline and at 9 months measured form the mid-buccal aspect of the gingival margin to the mucogingival line
Pain assessment at the donor site 7 days Visual Analogue Scale
number of analgesic pills consumed per day 7 days counting number of analgesic pills per day
Recession width baseline-3-6-9 months distance between mesial and distal gingival margin of the tooth recorded on a horizontal line tangential at the CEJ to the nearest mm
Gingival thickness baseline and at 9 months determined 2mm apical to the gingival margin using standardised CBCT
Clinical attachment loss baseline-3-6-9 months measured from the CEJ to the bottom of the periodontal pocket to the nearest mm.
Probing pocket depth baseline-3-6-9 months measured from the gingival margin to the base of the periodontal pocket to the nearest mm
