Objectives: The aim of this study was to evaluate subepithelial connective tissue graft (SCTG) and guided tissue regeneration (GTR) to surgically treatment of gingival recession. Methods: Twelve-four gingival recession were treated and evaluated after 6,18 and 30 months. The clinical measurements were obtained at baseline, after 6, 18 and 30 months and included: gingival recession height decrease (GR), root coverage perceptual (RC), probing depth decrease (PD), clinical attachment gain (CA) and keratinized tissue increase (KT). Results: The results obtained were analyzed with t student test, Wilcoxson test, Friedman test, Tukey-Kramer test and Dunn test. The data obtained showed that 30 months after treatment both methods were efficient in RC (SCTG=95.5% and GTR=87.0%), GR (SCTG=3.9mm and GTR=3.3mm), PD (SCTG=1.2mm and GTR=1.6mm) and CA (SCTG=5.0mm and GTR=2.4mm). And SCTG was better in KT. IN SCTG there was stability of the results after 6 months compared to 18 and 30 months results for RC, GR, KT and CA, and improvement in PD. In GTR was stability of the results after 6 months for DP, and improvement for RC, GR, CA and KT compared to 18 and 30 months results. Conclusions: It can be concluded that GTR and SCTG are able to promote efficient result in gingival recession treatment and there was stability of the results or even improvement for a period of 30 months.
