Healing following periodontal reconstructive therapy may result in formation of a long junctional epithelium at the tooth-mucogingival flap interface. In the context of periodontal regeneration, this should be considered an expression of wound failure, where maturation of a root surface-adhering fibrin clot has been disturbed by disruptive forces and/or properties of the root surface1. Periodontal regeneration is defined as the reproduction or reconstitution of a lost or injured part so that form and function of lost structures are restored2. Inconsequence, periodontal regeneration includes regeneration of alveolar bone, cementum, periodontal ligament and gingiva; however, the tissue structure may not be anatomically or functionally perfect and may include some evidence of scarring.
