Comparing the Efficacy of CTG Versus Periocol® - GTR Membrane in the Treatment of Isolated Gingival Recession Defects: Two Case Reports

Abstract

Gingival recession is an apical displacement of gingival tissue which leads to root surface exposure causing aesthetic problem, attachment loss, hypersensitivity, and root caries. Connective Tissue Graft (CTG) is a gold standard procedure while GTR is also an effective and predictable surgical approach for recession coverage. Periocol® is sterile, type I bioresorbable collagen membrane of fish origin. The aim of this study is to comparatively evaluate the treatment of Miller class I and class II recession defects of maxillary anteriors by using CTG or PerioCol®- Guided Tissue Regeneration (GTR) membrane. To the author’s knowledge this is the first study comparing the efficacy of CTG with Periocol® GTR membrane. Two patients were selected and subjected to two different techniques i.e CTG and Periocol® - GTR membrane. Evaluation was done on the basis of percentage gain in root coverage and increase in the width of keratinized gingiva. Optimal results were achieved in both the cases regarding clinical measurements of recession coverage although greater coverage was seen in patient treated with Periocol®.  Both the treatment modalities can be utilized for gingival recession coverage but with limitations in both. Recession coverage with Periocol® can be used as another option besides CTG.
