富血小板血浆含有大量生长因子,能够促进牙髓细胞的迁移、增殖和分化,应用其直接盖髓可以诱导成牙本质样细胞的形成,有利于形成完整的修复性牙本质桥。本文从富血小板血浆的理化特性、细胞学作用和临床应用等方面对其应用于临床直接盖髓的前景作一展望。 Platelet-rich plasma contains a large number of growth factors, which can promote the migration, proliferation and differentiation of dental pulp cells. Using its direct pulp capping can induce the formation of odontoblast-like cells, which is conducive to the formation of a complete prosthetic dentin bridge. In this paper, we prospected the prospect of clinical pulp capping from the aspects of physicochemical properties, cytology and clinical application of platelet-rich plasma.
