Treatment of gingival recession: comparative study between subepithelial connective tissue graft and guided tissue regeneration / Tratamento da recessão gengival: estudo comparativo entre enxerto do tecido conjuntivo subepitelial e regeneração tecidual guiada

ABSTRACT

Background: Various procedures have been proposed to treat gingival recession, but few studies compare these procedures to each other. The purpose of this study was to evaluate a clinical comparison of subepithelial connective tissue graft (SCTG) and guided tissue regeneration (GTR) with a collagen membrane in the treatment of gingival recessions in humans. Methods: Twenty-four defects were treated in 12 patients who presented canine or pre-molar Miller Class and/or II bilateral gingival recessions. Both treatments were performed in all patients, and clinical measurements were obtained at baseline and 18 months after surgery. These clinical measurements included gingival recession height (GR), root coverage (RC), probing depth (PD), heratinized tissue width (KT), and final esthetic result...
