#mineralization

• Adamantogenesis — A complex physiological and biochemical process of formation, development, and mineralization of tooth enamel, carried out by specialized epithelial cells called adamantoblasts. This biological mechanism includes the secretion of an organic protein matrix followed by the massive deposition of hydroxyapatite crystals, resulting in the hardest mineral structure in the human body.
• Adamantolysis — A pathological or experimental process of destruction, dissolution, or structural disintegration of dental enamel, caused by the action of acids, bacterial enzymes, or severe metabolic disorders. This phenomenon leads to the demineralization of the enamel prism and the loss of tooth surface integrity, being the first stage in the development of deep carious lesions.
• Anion exchanger — A synthetic or natural macromolecular ion exchanger capable of binding and exchanging anions from aqueous solutions. This type of ion-exchange resin contains functional groups with a basic character fixed onto an insoluble polymeric matrix, widely utilized in industrial processes for demineralization, softening, and advanced purification of wastewater or drinking water.
• Anti-rachitic — Preventing, combating, or treating rickets; a substance, biological factor, or pharmaceutical preparation that promotes the fixation of calcium and phosphorus in the bone structure. It is traditionally applied to vitamin D (especially D3 or cholecalciferol), cod liver oil, and therapeutic treatments intended for infants and young children to ensure proper bone mineralization and prevent skeletal deformities.
• Apomagmatic — Pertaining to mineral deposits or hydrothermal solutions formed at great distances from the parent magmatic hearth or main intrusive body from which they originate; located at the extreme periphery of a zone of plutonic activity. In structural petrology, the term describes mineral precipitation processes occurring at low temperatures where residual fluids are highly diluted by groundwater.
