Abstract
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 P P <0.05).Conclusion: DBS and DE associated with CAF presented satisfactory clinical outcomes. However, DBS presented inferior morbidity, an important fact for decision‐making process.
