In order for periodontal regeneration to occur, progenitor cells must migrate to the denuded root surface, attach to it, proliferate and mature into an organized and functional fibrous attachment apparatus. Significant advances have been made during the last decade in understanding the factors controlling the migration, attachment and proliferation of cells. A group of naturally occurring molecules known as polypeptide growth factors in conjunction with certain matrix proteins, are key regulators of these biological events. Of these, the fibroblast growth factors (FGFs) appear to have an important role in periodontal wound healing. The purpose of this review is to summarize current information on these growth factors with emphasis on their potential implications in periodontal wound healing and regeneration.
