2. Hydroxyapatite - Wikipedia

   en.wikipedia.org/wiki/Hydroxyapatite

   Carbonated calcium-deficient hydroxyapatite is the main mineral of which dental enamel and dentin are composed. Hydroxyapatite crystals are also found in pathological calcifications such as those found in breast tumors, [8] as well as calcifications within the pineal gland (and other structures of the brain) known as corpora arenacea or "brain ...

3. Calcium hydroxyphosphate - Wikipedia

   en.wikipedia.org/wiki/Calcium_hydroxyphosphate

   Calcium hydroxyphosphate (calcium phosphate tribasic, tribasic calcium phosphate, hydroxyapatite, HAp) is an inorganic chemical compound that is made up of calcium, hydrogen, oxygen and phosphorus. Its formula is Ca 5 (OH)(PO 4) 3. [1] It is found in the body and as the mineral hydroxyapatite. [citation needed]

4. Tricalcium phosphate - Wikipedia

   en.wikipedia.org/wiki/Tricalcium_phosphate

   It is also known as tribasic calcium phosphate and bone phosphate of lime (BPL). It is a white solid of low solubility. Most commercial samples of "tricalcium phosphate" are in fact hydroxyapatite. [4] [5] It exists as three crystalline polymorphs α, α′, and β. The α and α′ states are stable at high temperatures.

5. Tooth enamel - Wikipedia

   en.wikipedia.org/wiki/Tooth_enamel

   The primary mineral is hydroxyapatite, which is a crystalline calcium phosphate. [4] Enamel is formed on the tooth while the tooth develops within the jaw bone before it erupts into the mouth. Once fully formed, enamel does not contain blood vessels or nerves, and is not made of cells.

6. Bisphosphonate - Wikipedia

   en.wikipedia.org/wiki/Bisphosphonate

   The general chemical structure of bisphosphonate. The R-groups determine the chemical properties of the drug, and distinguishes individual types of bisphosphonates. This chemical structure affords a high affinity for calcium hydroxyapatite, allowing for rapid and specific skeletal targeting.

7. Calcium phosphate - Wikipedia

   en.wikipedia.org/wiki/Calcium_phosphate

   Calcium phosphate stones account for approximately 15% of kidney stone disease. Calcium phosphate stones tend to grow in alkaline urine, especially when Proteus bacteria are present. It is the most common type in pregnant women. [6] Calcium phosphate is the usual constitution of microcalcifications of the breast, particularly dystrophic ...
