The treatment of advanced gingival recessions presents a clinical challenge due to the lack of adequate interdental support. The objective of this research was to compare the results of root coverage of surgical techniques for root coverage of Tunnel and Coronary Positioned Flap (RPC), both associated with Subepithelial Connective Tissue Graft (ETCS), in patients with Cairo RT2 gingival recession. Forty-one Cairo RT2 recessions were selected, in 18 patients, divided into 2 groups to undergo root coverage surgery. Patients were evaluated at 0, 90 and 180 days postoperatively to verify the height and width of the recession, probing depth, probing bleeding, clinical attachment level, gingival thickness and height of the keratinized tissue band (p <0.05%). There was a gain in gingival height of 1.84 ± 1.03mm in the Tunnel + ETCS group and 2.33 ± 0.90mm in the RPC + ETCS group, with no statistically significant differences between the groups, obtaining an average coverage of 62%. Full coverage was achieved in 17% of recessions. Both techniques showed significant improvement in the periodontal parameters evaluated. Only the keratinized gingiva showed better results in the RPC group.
