Conditions
Shallow Vestibular Depth
Gingival Recession

Procedure: Free gingival graft
Procedure: Vertically coronally advanced flap combined with connective tissue graft.
Registration Number
NCT05777811
Lead Sponsor
Hacettepe University
Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures
NameTimeMethod
Vestibule depth 212th month.

The distance between the free gingival margin and the most apical point of the vestibul.

Vestibule depth 112th month

The distance between the free semento-enamel junction and the most apical point of the vestibul.

Secondary Outcome Measures
NameTimeMethod
Recession depth (RD)12th month.

Measured as the distance from the cementoenamel junction to the gingival margin

Probing depth (PD)12th month.

Measures as the distance from the apical of gingival sulcus to the gingival margin.

Clinical attachment level (CAL)12th month.

measured as the distance from th tip of the probe inserted into the sulcus to de cementoenamel junction.

Gingival thickness (GT)12th month.

determined 1.5 mm apical to the gingival margin, measured with the caliper accurete to the nearest 0.1 mm.

Dentine hypersensitivity (DH)6th week

Dentine hypersensitivity (DH) was evaluated with air evaporative stimulus method at baseline and T2. After placement of finger(s) for preserving the nearby teeth, the recession sites were subjected to evaporative stimulus comprised of 1-second air blast from 1 to 3 mm distance by using the air spray at 40-65 psi pressure and 19±50C. After application, the patients were requested to give a score to their DH between 0 (=no pain) and 10 (=extreme pain).

Wound healing index (WHI)2nd week

Wound healing index (WHI) was recorded two-weeks after surgery. The wound surface was visually inspected and the soft tissue healing was defined as 'uneventful' (score 1), 'slightly disturbed' (score 2) or 'poor' (score 3) based on the presence and severity of the items including patient discomfort, erythema, edema, suppuration and flap dehiscence.

Tissue appearance (TA)6th week

Tissue appearance (TA) was evaluated by asking the patients to score the consistency, contour, color match, keloid formation degree and contiguity of their treated sites at T2. The scores were collected as points, shown in parentheses, by asking the consistency as firm (1p) or spongy (0p); contour as presence (2p) or absence (0p) of knife-edged and scalloped gingival margin; color match as excellent (3p), good (2p), adequate (1p) or unsatisfactory (0p); keloid formation degree as absent (1p) or present (0p); contiguity as the presence (-1p) or absence (0p) of each perceptible incision mark.

Keratinized tissue height (KTH)12th month.

measured from the most apical point of the recession at the gingival margin to the mucogingival line.

Patient expectations (PE)6th week

Patient expectations (PE) were evaluated by requesting from the patients to rate their treatment results at T2, as satisfactory or not, in terms of appearance, experience and obtained root coverage.

Aesthetics (A)6th week

Aesthetics (A) was evaluated by the patient at T1 by rating its level as excellent, good, fair or poor.
