  2. Hydroxyapatite - Wikipedia

    en.wikipedia.org/wiki/Hydroxyapatite

    Hydroxyapatite (IMA name: hydroxylapatite [5]) (Hap, HAp, or HA) is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4) 3 (OH), often written Ca 10 (PO 4) 6 (OH) 2 to denote that the crystal unit cell comprises two entities. [6] It is the hydroxyl endmember of the complex apatite group.

  3. Remineralisation of teeth - Wikipedia

    en.wikipedia.org/wiki/Remineralisation_of_teeth

    When fluoride ions are present in plaque fluid along with dissolved hydroxyapatite, and the pH is higher than 4.5, [16] a fluorapatite-like remineralised veneer is formed over the remaining surface of the enamel; this veneer is much more acid-resistant than the original hydroxyapatite, and is formed more quickly than ordinary remineralised ...

  4. Amorphous calcium phosphate - Wikipedia

    en.wikipedia.org/wiki/Amorphous_calcium_phosphate

    Amorphous calcium phosphate in combination with casein phosphopeptide has been used as a dental treatment to treat incipient dental decay. ACP sees its main use as an occluding agent, which aids in reducing sensitivity. Studies have shown that it does form a remineralized phase of hydroxyapatite consistent with the natural enamel.

  5. Apatite - Wikipedia

    en.wikipedia.org/wiki/Apatite

    Apatite is a group of phosphate minerals, usually hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH −, F − and Cl − ion, respectively, in the crystal. The formula of the admixture of the three most common endmembers is written as Ca 10 ( PO 4 ) 6 (OH,F,Cl) 2 , and the crystal unit cell formulae of the ...

  6. Biomineralization - Wikipedia

    en.wikipedia.org/wiki/Biomineralization

    The most common biogenic phosphate is hydroxyapatite (HA), a calcium phosphate (Ca 10 (PO 4) 6 (OH) 2) and a naturally occurring form of apatite. It is a primary constituent of bone, teeth, and fish scales. [33] Bone is made primarily of HA crystals interspersed in a collagen matrix—65 to 70% of the mass of bone is HA.

    High blood pressure is caused by the force of blood flow in the arteries being too high. The DASH diet includes heart-healthy foods that lower blood pressure.

  8. Tooth decay - Wikipedia

    en.wikipedia.org/wiki/Tooth_decay

    These minerals, especially hydroxyapatite, will become soluble when exposed to acidic environments. Enamel begins to demineralize at a pH of 5.5. [ 45 ] Dentin and cementum are more susceptible to caries than enamel because they have lower mineral content. [ 46 ]

  9. Chemical process of decomposition - Wikipedia

    en.wikipedia.org/wiki/Chemical_process_of...

    Decomposition in animals is a process that begins immediately after death and involves the destruction of soft tissue, leaving behind skeletonized remains. The chemical process of decomposition is complex and involves the breakdown of soft tissue, as the body passes through the sequential stages of decomposition. [2]
