Periodontal regenerative therapy with coverage of previously restored root surfaces: case reports.

Two case reports are presented to demonstrate a treatment that restores proper esthetics, cures hypersensitivity, and enhances periodontal support for cases of root caries or failing Class V restorations associated with gingival recessions. The procedure involves removing the existing restoration, elevating a trapezium-shaped full thickness flap, root planing to achieve a desired concave shape, and placing a barrier membrane. In both cases, satisfying clinical results have been maintained for 18 months.
