A comparative evaluation of the effectiveness of subpedicle acellular dermal matrix allograft with subepithelial connective tissue graft in the treatment of isolated marginal tissue recession: A clinical study

INTRODUCTION: The most common problem encountered in our day to day practice is exposed root surface or a tooth getting long. The main indication for root coverage procedures are esthetics and/or cosmetic demands followed by the management of root hypersensitivity, root caries or when it hampers proper plaque removal. Over the years, various techniques have been used to achieve root coverage. AIM AND OBJECTIVES: The aim of this study was to compare the effectiveness of subpedicle acellular dermal matrix allograft (ADMA) with subepithelial connective tissue graft (SCTG) in the treatment of isolated marginal tissue recession. MATERIALS AND METHODS: Twenty systemically healthy patients aged between 18 to 50 years (mean age29.7±4.35 years) with a recession defect on the labial and the buccal surfaces of any teeth were selected for the study. Ten patients received the test treatment (ADMA), ten patients received the control treatment (SCTG). Clinical recordings assessed at baseline, three months and six months post surgery, included Plaque index (PI), Papillary bleeding index (PBI), Gingival recession (REC), Probing pocket depth (PPD), Clinical attachment level (CAL) and Width of keratinized gingival (WKG). RESULTS: Test group (ADMA) showed 86.93% mean root coverage while control group (SCTG) showed 84.72% at six months post surgery. Mean increase in the width of keratinized gingiva was significantly greater in the SCTG group (3.3±0.48mm) compared to ADMA group (2.4±0.51mm). Conclusion: Both the treatment produced a significant reduction in gingival recession and probing pocket depth and significant gain in clinical attachment level and width of keratinised gingiva.
