Background: The aim of this study was to perform a systematic review (SR) of randomized controlled trials (RCTs) to explore if periodontal plastic surgery procedures for the treatment of single and multiple gingival recessions (Rec) may improve aesthetics at patient and professional levels.
Material and Methods:In order to combine evidence from direct and indirect comparisons by different trials a Bayesian network meta-analysis (BNM) was planned. A literature search on PubMed, Cochrane libraries, EMBASE, and hand-searched journals until January 2015 was conducted to identify RCTs presenting aesthetic outcomes after root coverage using standardized evaluations at patient and professional level.Results: A total of 16 RCTs were selected in the SR; 3 RTCs presenting professional aesthetic evaluation with Root coverage Aesthetic Score (RES) and 3 showing final self-perception using the Visual Analogue Scale (VAS Est) could be included in a BNM model. Coronally Advanced Flap plus Connective Tissue Graft (CAF+CTG) and CAF+Acellular Dermal Matrix (ADM) and Autologous Fibroblasts (AF) were associated with the best RES outcomes (best probability = 24% and 64%, respectively), while CAF+CTG and CAF+CTG+Enamel matrix Derivatives (EMD) obtained highest values of VAS Est score (best probability = 44% and 26%, respectively).
Conclusions: Periodontal Plastic Surgery (PPS) techniques applying grafts underneath CAF with orwithout the adding of EMD are associated with improved aesthetics assessed by final patient perception and RES as professional evaluation system. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 To compare, using a Bayesian network meta-analysis, the efficacy of periodontal plastic surgery procedures to improve aesthetics as assessed by professional and patient scores.
Principal findings:Coronally Advanced Flap plus Connective Tissue Graft (CAF+CTG) and CAF plus Acellular Dermal Matrix (ADM) and Autologous Fibroblasts (AF) were associated with the highest professional outcomes rated by means of Root Coverage Aesthetics Score (RES). CAF+CTG and CAF+CTG plus Enamel Matrix Derivatives (EMD) obtained highest values in term of patient satisfaction rated by Visual Analogue Scale (VAS est).
Practical implications:Grafting underneath the Coronally Advanced Flap with or without the adding of Enamel Matrix Derivatives is associated with highest aesthetic outcomes at professional and patient level.
