Talc, or talcum, is a clay mineral composed of hydrated magnesium silicate, with the chemical formula Mg 3 Si 4 O 10 (OH) 2.Talc in powdered form, often combined with corn starch, is used as baby powder.
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.
Poly-MVA is promoted with claims that it can treat a variety of human diseases, including cancer and HIV/AIDS. [1] The promotional effort is supported by customer testimonials, but there is no medical evidence that Poly-MVA confers any health benefit and some concern it may inhibit the effectiveness of mainstream cancer treatments if used at the same time.
Mineralized tissues combine stiffness, low weight, strength and toughness due to the presence of minerals (the inorganic part) in soft protein networks and tissues (the organic part). [ 1 ] [ 2 ] There are approximately 60 different minerals generated through biological processes, but the most common ones are calcium carbonate found in mollusk ...
The affected areas of the tooth change color and become soft to the touch. Once the decay passes through the enamel, the dentinal tubules , which have passages to the nerve of the tooth, become exposed, resulting in pain that can be transient, temporarily worsening with exposure to heat, cold, or sweet foods and drinks.

P11-4 is a self-assembling β-peptide. It builds a 3-D bio-matrix with binding sites for Calcium-ions serving as nucleation point for hydroxyapatite (tooth mineral) formation. The high affinity to tooth mineral is based on matching distances of Ca-ion binding sites on P11-4 and Ca spacing in the crystal lattice of hydroxyapatite.
This leads to calculus buildup, which compromises the health of the gingiva (gums). Calculus can form both along the gumline, where it is referred to as supragingival ( ' above the gum ' ), and within the narrow sulcus that exists between the teeth and the gingiva, where it is referred to as subgingival ( ' below the gum ' ).
Struvite (magnesium ammonium phosphate) is a phosphate mineral with formula: NH 4 MgPO 4 ·6H 2 O. Struvite crystallizes in the orthorhombic system as white to yellowish or brownish-white pyramidal crystals or in platy mica-like forms. It is a soft mineral with Mohs hardness of 1.5 to 2 and has a low specific gravity of 1.7. It is sparingly ...
