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 ...
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.
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 ...
Fluoride is commonly found in toothpastes. Fluoride can be delivered to many parts of the oral cavity during brushing, including the tooth surface, saliva, soft tissues and remaining plaque biofilm. [4] Some remineralization methods may work for "white spot lesions" but not necessarily "intact tooth surfaces". [19]
Post radiation maxillary bone osteonecrosis is something that is found more in the lower jaw (mandible) rather than the maxilla (upper jaw) this is because there are many more blood vessels in the upper jaw. [7] The symptoms of this are very similar to the symptoms of medication-related osteonecrosis of the jaw (MRONJ). Patients are in a lot of ...
Rates are rising sharply among younger people: The percentage of people younger than 55 diagnosed with colon cancer almost doubled between 1995 and 2019, leaping from 11% to 20% of cases.
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 ...
The Environmental Working Group has found 21 oat-based cereals marketed to children to have "troubling levels" of the chemical. Study: 21 popular cereals found to have cancer-linked Roundup ingredient
