Summary

In this randomized controlled clinical trial we will compare the clinical outcome of Full thickness palatal graft technique (FTPGT) to coronally advanced flap (CAF) + subepithelial connective tissue graft (SCTG) in the treatment of RT1 (Cairo et al. classification) recessions.

Forty patients, presenting at least one RT1 recession, will be treated with bilaminar procedures . 20 participants will receive FTPGT approach (test group) and 20 patients will undergo CAF+SCTG (control group). Complete root coverage (CRC) will be assumed as the main outcome at 12 months after treatment. Gingival recession (GR), clinical attachment level (CAL), pocket depth (PD), keratinized tissue width (KT,) thickness of keratinized tissue (GT) will be assessed at baseline and 12 months after treatment. Patient-reported outcome measures (PROMs) will be reported: namely, the number of painkiller tablets taken during the first week, the degree of general discomfort (D) experienced assessed on a VAS scale (0-10), the extent of changes in their eating habits (CFH), dentin hypersensitivity (DH), patient-reported aesthetic satisfaction (PRES) quantified on a VAS scale (0-10) and overall treatment satisfaction (OTS).

Conditions

  • Gingival Recession

Interventions

PROCEDURE

FTPGT treated patients

The recipient bed will be prepared according to Langer\&Langer modified technique. Intrasulcular incision will be performed from at least one tooth mesial and one tooth distal to the tooth with gingival recession, without vertical incisions.A split-thickness flap will be raised.The harvest of palatal graft will be done using FTPG technique. An incision, parallel to the gingival margin, deep to the bone, will be made. At the center of this incision, a "U" shaped one about 1-2mm deep will made, with the convex side towards the palatine vault.The width of the "U" incision will be equal to the width of the GR and the length will be 1mm greater.A split-thickness dissection of the area surrounding the "U" shaped incision will be done.The graft will be removed by detaching it from the bony surface.The graft will be made up of an apico-lateral portion of connective tissue and periosteum, and of a full-thickness central part.The palatal graft will be adapted to the recipient site and sutured.

PROCEDURE

CAF+SCTG treated patients

According to De Sanctis \& Zucchelli, a tension-free trapezoidal flap will be elevated by the split-full-split technique and the anatomic papillae will be de-epithelialized. A 1-mm thick SCTG will be harvested from the palate as epithelialized graft. The height of the graft was equal to the distance between the buccal bone crest and the CEJ. After epithelium removal, the graft was positioned and sutured 1mm apical to the cement-enamel junction with 5-0 resorbable sutures . The SCTG will then be covered by the tension-free coronally positioned flap, sutured about 2mm over the CEJ by 5-0 silk sutures.
