This study was a single-arm trial to obtain preliminary data on the efficacy of collagen membranes impregnated with recombinant human fibroblast growth factor (rhFGF-2) in the treatment of Miller's class I and class II gingival recessions.

Soft tissues can be regenerated to cover root exposure and a thin biotype can be converted into a thick biotype by using recombinant human growth factor technology. A recent review stated that growth factors could enhance soft tissue regeneration which includes restoration of mucogingival architecture and regeneration of periodontal hard and soft tissues including bone, cementum and periodontal ligament fibers. Fibroblast growth factor-2 (FGF-2), a heparin-binding cytokine with strong angiogenic activity stimulates the proliferation of undifferentiated mesenchymal cells. These functions can be applied in mucogingival surgery as FGF-2 promotes bone and cementum formation and exhibits an increased potential to promote periodontal regeneration in recession defects.

Exclusion Criteria:

• 1. Recessions associated with root demineralization/caries, deep cervical abrasion or pulpal pathology, 2. Patients with history of systemic conditions affecting periodontium and, 3. Smokers.](streamdown:incomplete-link)
