Objectives: to compare a novel vertical Y-shaped tunnel approach (YST) with modified coronally advanced tunnel technique (MCAT), both with connective tissue graft (CTG), in the treatment of single gingival recession (GR). Materials and Methods: Patients with Miller's Class I GR defects in the esthetic zone were selected and randomly allocated to MCAT +CTG (group I, n =16 sites): and YST+CTG (group II, n =16 sites). The following measurements were recorded at baseline, 1, 3 and 6 months post-surgically; percentage of root coverage (primary outcome), complete root coverage (CRC), recession Depth (RD), recession width (RW), width of the keratinized tissue (KTW), plaque index (PI), and gingival index (GI). Probing depth (PD), clinical attachment level (CAL) and gingival thickness (GT) were measured at baseline and after 6 months. Professional esthetic evaluation (EE), patient-reported satisfaction, pain index and duration of the surgical procedures were also recorded. Results: Six months after surgery, five patients (MCAT) and none (YST) obtained CRC, RC% was 81.04 ±9.32% (MCAT) and 59.48 ±7.79% (YST). MCAT achieved significantly better reduction in RD and RW and better CAL and KTW gain (p<0.05). No intergroup significant difference was recorded regarding PI, GI, PD, and GT (P>0.05). Regarding EE, a significant intergroup difference was reported in favor of MCAT (p<0.05). The study failed to find significant differences related to patient-centred outcomes.
