This manuscript provides a stateâ ofâ theâ art review on the efficacy of biologics in root coverage procedures, including enamel matrix derivative, plateletâ derived growth factor, platelet concentrates, and fibroblastâ growth factorâ 2. The mechanism of action and the rationale for using biologics in periodontal plastic surgery, as well as their anticipated benefits when compared with conventional approaches are discussed. Although the clinical significance is still under investigation, preclinical data and histologic evidence demonstrate that biologicâ based techniques are able to promote periodontal regeneration coupled with the provision of tooth root coverage.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154295/1/jper10426_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154295/2/jper10426.pd
