Buccal vestibule depth was recorded using two different measurement methods. First, the distance between the cementoenamel junction and the deepest point of the vestibule sulcus was measured and recorded as VD1. Then, the distance between the gingival margin and the base of the vestibule sulcus was measured and recorded as VD2.
In this comparative trial, 50 patients with shallow vestibules and Type 1/2 recessions will be treated with either a vertically coronally advanced flap + connective tissue graft or a free gingival graft. At baseline, 3rd-month, 6th-month, and 12th-month visits, the following parameters will be evaluated: buccal vestibular depth, keratinized tissue height, gingival thickness, recession depth, recession width, probing depth, and clinical attachment level. Keratinized tissue change, gingival thickness change, root coverage, clinical attachment gain, and complete root coverage will be calculated. The wound healing index, tissue appearance, patient expectations, aesthetics, and dentin hypersensitivity will be assessed at baseline and at the 6th week.
