Abstract
Enamel matrix proteins (EMP) are deposited on the surface of developing roots before dentin formation and may play a role in osteogenesis. Amelogenins (Am) are the main and active component in EMPs. Studies had showed great clinical values of EMPs in periodontal regenerative treatment and other fields. By affecting the expression of growth factors and inflammatory factors, EMPs could act on various periodontal regeneration-related cells to promote angiogenesis, anti-inflammation, bacteriostasis and tissue healing, achieving the clinical effect of periodontal tissue regeneration (newly generated cements and alveolar bones as well as functionally penetrated periodontal ligament). EMPs alone or combined with bone graft material and barrier can be used for regenerative surgical treatment in intrabony defects and degree Ⅱ furcation-involved at maxillary buccal or mandibular teeth. EMPs can also be adjunctively used to treat recession type 1 or 2 gingival recessions, forming periodontal regeneration on the exposed root surface. Through a comprehensive understanding of the principle and current clinical application of EMPs on periodontal regeneration, we can look forward to their future development. The development of recombinant human amelogenin to replace animal-derived EMPs through bioengineering technologies, the study of the clinical application of EMPs combined with other collagen biomaterials, and the specific application of EMPs in severe soft and hard periodontal tissue defects and peri-implant lesions are all important development directions of future EMPs-related researches.
