Gingival Recession, Tooth Abrasion
About this trial
This is an interventional treatment trial for Gingival Recession

Experimental
Connective tissue graft (CTG)
CTG plus resin composite restoration
After local anesthesia, the surgical procedure performed was the trapezoidal-type of Coronally advanced flap (CAF). After the flap was raised, the exposed root surface was gently scaled and planed until it became smooth. Afterward, a thin and small connective tissue graft that was sutured over the root surface. Then, the flap was coronally positioned and sutured to completely cover the graft.
After local anesthesia, a sterile rubber dam was placed to isolate the operative field and the coronal zone of the non-carious cervical lesion restoration was performed with a nanocomposite resin, following the manufacturer's instructions. The apical margin of the restoration was place 1 millimeter beyond to the cemento-enamel junction estimation. In the next session, the surgical procedure performed was the trapezoidal-type of CAF. After the trapezoidal-type of CAF flap was raised, a thin and small connective tissue graft that was sutured over the restoration surface. Then, the flap was coronally positioned and sutured to completely cover the graft.
