Clinical and patient‐centered outcomes using two types of subepithelial connective tissue grafts: A split‐mouth randomized clinical trial

Background This split‐mouth randomized clinical trial compared two different types of subepithelial connective tissue grafts (SCTG) considering clinical parameters and patient‐centered outcomes in patients with bilateral recession type 1 multiple gingival recessions after 6 months postoperatively. Methods A total of 21 patients were surgically treated with coronally advanced flap (CAF) associated with SCTG harvested by: double blade scalpel (DBS) and de‐epithelialized (DE) SCTG. Periodontal clinical parameters and esthetics were evaluated by a calibrated periodontist at baseline and after 6 months. Patient‐centered outcomes related to pain/discomfort and esthetics were assessed with visual analogue scale after 7 days and 6 months, respectively. Results All clinical parameters, with the exception of probing depth, demonstrated differences in intragroup evaluation, comparing baseline to 6‐month evaluation (P
