Er,Cr:YSGG Laser For Recipient Bed Bio-modification And Connective Tissue Harvesting in Treatment of Gingival Recession

The Use Of Er,Cr:YSGG Laser For Recipient Bed Bio-modification And De-epithelialized Palatal Graft Harvesting In The Treatment of Gingival Recession Defects -(Randomized Clinical Trial)

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.

Inclusion Criteria:

1. Single class I, II Miller gingival recession defects (≥ 2mm in depth), presence of identifiable buccal cemento-enamel junction (CEJ) and presence of a step ≤ 1 mm at CEJ.
2. Controlled periodontal disease
3. Full-mouth plaque score of <10%; full-mouth gingival score of <15%
4. Patients available for 9 months follow-up period.

Exclusion Criteria:

1. Smokers.
2. Pregnant and lactating females.
3. Taking medications known to interfere with periodontal tissue health or healing.
4. Previous periodontal surgery on the involved sites.
5. Non-vital teeth.
6. Molar teeth.
7. Recession defects associated with caries or restoration.
8. Occlusal interferences.
9. Taking anti-inflammatory drugs or antibiotics in the past 6 months.
