The present study introduces a novel “anatomic recession ratio” (ARR) and evaluates the clinical outcomes of using a tunnel technique (TUN) with a connective tissue graft (CTG) for root coverage (RC). Sixteen systemically healthy patients contributing a total of 33 recession types 1 and 2 were treated with TUN + CTG. The predictive value of a panel of baseline clinical parameters (ARR) on RC was evaluated 12 months postoperatively. At 12 months, mean recession depth decreased from 2.74 ± 0.22 mm to 0.46 ± 0.13 mm (P < .0001); 19 sites (58%) showed complete RC, and the mean RC rate was 88.85% ± 2.73%. The mean ARR value was 0.74 ± 0.3, revealing a positive correlation with RC (r²: 0.73, P < .0001). The 12-month esthetic evaluation resulted in a score of 8.52 ± 1.75 using the root coverage esthetic score. TUN + CTG is effective in reducing recession depth and obtaining good esthetic outcomes. Within the limits of the present study, it may be suggested that ARR has potential as an analytical baseline parameter for RC outcomes with TUN + CTG.
