| Still, the idea that hydroxyapatite in buried bone undergoes gradual change to fluorapatite is a correct one. |
| Bone consists of collagen banded fibrils sprinkled with tiny crystals of the mineral hydroxyapatite, which is basically calcium phosphate. |
| For a durable anchoring in the bone, the plasma spray method is used to deposit a hydroxyapatite coating on the corundum-blasted surface. |
| Yet only one atomic arrangement is suitable for an engagement ring. The same is true of hydroxyapatite, the material that bones are made of. |
| The calcium ions in saliva are liable to form calcium hydroxyapatite crystals, the mineral form of calcium used for the formation of tartar. |
| Bisphosphonates are small inorganic molecules that bind to a substance called hydroxyapatite on the surface of damaged bones. |
