Subepithelial connective tissue graft associated with apicoectomy and root-end fillings in the treatment of deep localized gingival recession with apex root exposure: case report.

Periodontal reconstructive surgery procedures seek to correct mucogingival defects, including gingival recession. This case report describes the use of a subepithelial connective tissue graft (SCTG) associated with root-end fillings using mineral trioxide aggregate (MTA) for the treatment of Miller Class II recession with root apex exposure. A partial-thickness double pedicle flap was made, followed by root preparation with curette and bur finishing. The exposed root apex was removed and the canal was filled with MTA. An SCTG taken from the palate was placed over the root surface and covered with the double pedicle flap. Twelve months after treatment, a reduction from 11 mm to 1 mm in gingival recession was achieved, covering 91% of the root. Repair in the periapical region was determined with radiographs. A 1.0-mm probing depth was measured, and no bleeding was observed on probing. There was an adequate keratinized tissue band, along with esthetic tissue contour and coloration. This case report serves as an example of how the grafting of subepithelial connective tissue can be successfully accomplished in tandem with MTA for the treatment of isolated Miller Class II gingival recession with root apex exposure.
