Bone tissue requires minerals such as calcium, phosphorus, magnesium, fluoride, and manganese, for its overall health and structural integrity. Calcium ions, and phosphorus in the form of inorganic phosphate, combine to form hydroxyapatite crystals, which are the major component of the mineralized bone matrix. However, other ions, such as magnesium and fluoride, are also incorporated into these crystals. In fact, fluoride ions can replace hydroxyl ions in hydroxyapatite crystals to form more stable and less acid–soluble fluorapatite crystals. Additionally, magnesium and fluoride ions can also control bone cell functions by regulating specific enzyme and hormonal activities. Similarly, manganese ions also act as a cofactor to several enzymes, including those involved in synthesizing glycosaminoglycans. These glycosaminoglycans are a part of the proteoglycans, which along with collagen fibers, constitute the organic bone matrix. Due to their intricate role in the formation and maintenance of bone tissue, excess or deficiency of minerals in the body can lead to severe ailments. For example, excessive accumulation of fluoride in the bones causes skeletal fluorosis.
