Résumé
To evaluate whether microsurgery gains better result in root coverage compared to conventional surgical techniques. A number of databases were searched to identify eligible studies from January 1992 to January 2015. The following outcomes were evaluated: number of sites exhibiting complete root coverage and patients' esthetic satisfaction. Four Randomized Clinical Trials [RCTs] fulfilled the inclusion criteria. A pooled estimate from the two RCTs regarding sub-epithelial connective tissue grafts [SCTG] showed significant achievement in complete root coverage in the microsurgical group [relative risk [RR]:1.63; 95% confidence interval [Cl]: 1.12 to 2.36; P=0.01] with acceptable heterogeneity. The other two studies were about coronal advanced flap [CAP] with enamel matrix derivative or free rotated papilla autograft and did not qualify for meta-analysis. Patients' esthetic satisfaction was analyzed only by one study. Using microsurgical technique for treating gingival recessions may be effective in achieving complete root coverage for SCTG
