牙本质是牙齿中主要的矿化胞外基质 ,其晶体基本结构为羟磷灰石 (HA) ,晶体中存在一种纳米粒子 ,参与牙本质初始晶体的形成。牙本质非胶原蛋白在HA成核及生长中起着重要作用。钙的转运在牙本质矿化过程中以跨细胞转运为主。
Dentin is the main mineralized extracellular matrix in the tooth. The basic structure of the crystal is hydroxyapatite (HA). There is a kind of nano-particles in the crystal, which is involved in the formation of the initial dentin. Dentin non-collagen plays an important role in HA nucleation and growth. Calcium transport in the process of dentin mineralization transcellular transport-based.
