Abstract

There is considerable variation in the composition of primary and secondary dentine. In general, secondary deposits, regardless of type, contain less calcium, phosphorous, and collagenous matrix per unit volume when compared to primary dentine. Fluoride levels show the reverse tendency. These observations suggest a more open, porotic structure for secondary deposits.

摘要

原发性牙本质和继发性牙本质的组成存在相当大的差异。一般来说，与原发性牙本质相比，继发性牙本质沉积物，无论其类型如何，每单位体积所含的钙、磷和胶原基质都较少。氟含量则呈现相反的趋势。这些观察结果表明继发性牙本质沉积物具有更开放、多孔的结构。
