Values are presented as number (%) or mean±standard deviation (range). Data are shown as follow: CAL gain ≥1 mm, recession <1 mm: treatment successful; CAL gain <1 mm, recession >1 mm: treatment failure; residual pocket depth, no significance in COM.

COM: composite outcome measure, SFA: single-flap approach, DFA: double-flap approach, CAL: clinical attachment level, SD: standard deviation.
