牙本质
牙本质（dentin），也称为象牙质，是构成牙齿主体的微黄色组织，介于牙釉质与牙髓之间。牙本质的组成70％为无机物（主要为钙和磷），20％为有机物，10％为水分。硬度低于牙釉质，高于牙骨质。
和牙釉质不同的是，它终身都会继续不断地生长，因此当有蛀洞产生会自行长出新的牙本质修复。
牙本质内外贯穿牙本质小管
英语百科
Dentin 牙本质
Dentin (/ˈdɛntᵻn/) (American English) or dentine (/ˈdɛnˌtiːn/ or /ˌdɛnˈtiːn/) (British English) (Latin:substantia eburnea) is a calcified tissue of the body and, along with enamel, cementum, and pulp, is one of the four major components of teeth. It is usually covered by enamel on the crown and cementum on the root and surrounds the entire pulp. By weight, 45% of dentin consists of the mineral hydroxylapatite, 33% is organic material, and 22% is water. Yellow in appearance, it greatly affects the color of a tooth due to the translucency of enamel. Dentin, which is less mineralized and less brittle than enamel, is necessary for the support of enamel. Dentin rates approximately 3 on the Mohs scale of mineral hardness.
