Treatment of gingival class I or class II recession using subepithelial connective tissue graft and acellular dermal matrix allograft

The present randomized control was conducted clinically to evaluate the effectiveness of Acellular Dermal Matrix Allograft (ADMA) and Subepithelial Connective Tissue Graft (SCTG) in combination with Coronally Positioned Flap (CPF) in the treatment of Miller's class I and II multiple gingival recession in aesthetic areas. A total of 20 patients aged between 18 to 40 years were selected for this study, meeting all the criteria for inclusion. 10 patients were treated with ADMA and 10 patients with SCTG in combination with CPF. Various clinical parameters were assessed viz. probing pocket depth (PPD), clinical attachment level (CAL), gingival recession height (RH) and width of keratinized gingiva (WKG) at baseline and 6 months after surgery. The mean RH at baseline in the control and test groups was 3.05 ±0 .55(mean± SD) and 2.60 ±.99 respectively. At 3 months the mean RH was found to be 1.60±0.74 and 1.05 ± .60 in the control and test group respectively. The mean percentage of root coverage (MRC%) at 6 months in the control and test group was 65.69 ±26.52 (mean± SD) and 65.54 ±.9.16 respectively but no statistically significant difference was seen between the two groups. The results of the study suggest that the combination of both subepithelial connective tissue graft and acellular dermal matrix graft with a coronally positioned flap can produce an equivalent amount of esthetic root coverage.
