Calcium Phosphate Mineral

The major components of apatite-mineralized tissue (bone, dentin, and enamel) are minerals (calcium phosphate), organics (collagen), and water. Bone and dentin consist of about 45-70 wt.% mineral and 10 wt.% water, and the rest is collagen with a small proportion of noncollagenous proteins [ 3 ]. Enamel is strikingly different in its …

Bioceramic-Based Root Canal Sealers: A Review

In phase I, monobasic calcium phosphate reacts with calcium hydroxide in the presence of water to produce water and hydroxyapatite. In phase II, the water derived from the dentin humidity, as well as that produced by the phase I reaction, contributes to the hydration of calcium silicate particles to trigger a calcium silicate hydrate phase [ 28 ].
