Abstract
Introduction: Gingival recession (GR) is the displacement of the gingival margin apically to the cementoenamel junction (CEJ). In clinical practice, multiple adjacent GRs associated with non-carious cervical lesions (NCCL) are common. Complete root coverage (RC) is the goal in the treatment of GR. Coronal advancement flap (CAF) with or without connective tissue graft (CTG) is a viable alternative in the treatment of GR. The objective of this clinical case was to compare the clinical results of CAF and CAF + CTG used in the treatment of multiple gingival recessions.
Procedure: The root coverage procedure for quadrant 1, with type 1 GR, was CAF. The flap was displaced coronally and sutured 2 mm coronal to the CEJ. In quadrant 2 with type 1 GR, a slight ameloplasty was performed, and a CAF+ CTG was performed. The CTG was placed at the level of the CEJ and sutured at the base of the papillae. The flap was displaced and sutured 2 mm coronal to the CEJ. Some of the parameters evaluated before surgery and 6 months later: probing depth, GR dimension, apicocoronal width of keratinized tissue, presence of NCCL, and reduction in hypersensitivity.
Results: At 6 months, 100% root coverage was achieved with both techniques. Hypersensitivity was resolved with both treatment modalities. Only at sites treated with CAF + CTG was a “thin scalloped” to “thick flat” periodontal phenotype change observed.
Conclusions: Both techniques were effective in treating GR and dental hypersensitivity, but only CAF + CTG therapy showed a change in periodontal phenotype.
