Acellular dermal matrix and gingival connective in the treatment of periodontal recessions – comparative clinical evaluation in humans

Abstract

ABSTRACTDifferent periodontal surgical techniques have been proposed for the treatment of periodontal recessions. Among these, the graft of gingival connective tissue stands out for the high predictability of success. This work compared the clinical outcomes of treatment of periodontal recessions, using the gingival connective tissue grafts and acellular dermal matrix. A total of 72 recessions constituted the sample, divided equally into 2 groups. Group 1: treated with acellular dermal matrix graft (MDA) associated with the displaced: Group 2: treated with gingival connective tissue graft, also associated with the flap offset coronally. We evaluated the clinical parameters of probing depth, insert, clinical periodontal recession towards coronal-apical diameter mesio-distal of recessions, keratinized and mucosa thickness flap and influence of grafts in relation to root coverage. The initial measures were compared to those obtained with 45, 90 and 120 days after surgery. No statistically significant differences were found between the groups in terms of reduction of periodontal recessions, keratinized and mucosa flap thickness and of grafts in relation to root coverage. The Group 2 (CG) showed statistically significant reduction in the depth of drilling and clinical level of insertion, compared to group 1 (MDA). However, these differences were not clinically relevant. It was concluded that both the gingival connective tissue graft as the acellular dermal matrix can be used in the treatment of periodontal recessions, with a high predictability of success.Keywords: Gingival recession, connective tissue graft, acellular dermal matrix, periodontal surgery, gum recession, root coverage.
