RESUMO:

Gingival recession may cause dental hypersensitivity, esthetical discomfort and increase the prevalence of carious or non-carious cervical lesion. Furthermore, patients with thin gingival phenotype are more predisposed to develop mucogingival defects. Root coverage procedures using grafts placement has been the gold standard on this treatment. AIM: To compare the root coverage performed connective tissue graft and collagen matrix using the extended flap technique in single gingival recessions with thin gingival phenotype, at 6 months of follow-up. METHOD: This controlled, randomized, double-blind, split-mouth, clinical trial evaluated 26 patients with bilateral gingival recession subjected to root coverage procedure through extended flap technique with subepithelial connective tissue graft (control) and collagen matrix (test). The parameters evaluated were deep on probing, gingival recession, clinical attachment level, keratinized mucosa and bleeding on probing for teeth that received the graft and the distal and mesial teeth. In addition, to the keratinized mucosa thickness and gingival phenotype of the teeth that received the grafts, postoperative pain and quality of life at baseline, three and six months after surgery. Data were statistically analyzed through the tests of Friedman and Wilcoxon. The significance level of 5% was pre-established. PARTIAL RESULTS: To date, 13 men and 13 women were included in this study, with an average of 37.2 years (± 2.4). Statistically significant reductions were observed for gingival recession and significant gain in the clinical attachment level of both the grafts (p <0.001), distal (p=0.001) and mesial (p<0.001) teeth, within each group and in both treatment groups, during the follow-up. In addition, there was a significant increase of the keratinized mucosa (p <0.001) and mucosal thickness (p<0.001) of the teeth that received the grafts. CONCLUSION: Both treatments resulted in improved clinical parameters at six months of follow-up. The collagen matrix represents a suitable alternative to subepithelial connective tissue graft in the treatment of single gingival recessions in thin gingival phenotype.
