The glow of phosphorus itself originates from oxidation of the white (but not red) phosphorusâ a process now termed chemiluminescence. Together with nitrogen, arsenic, and antimony, phosphorus is classified as a pnictogen. Phosphorus is essential for life. White phosphorus, called WP (slang term Willie Peter) is used in military applications as incendiary bombs, for smoke-screening as smoke pots and smoke bombs, and in tracer ammunition. 2  It is also a part of an obsolete M34 White Phosphorus US hand grenade.
Such failures are inevitable when there is a deficiency of essential nutrients, particularly vitamins D, C, and niacin. There is especially strong evidence for a relationship between vitamin D deficiency and cavities. Dozens of studies were conducted in the 1930's and 1940's [16-27]. More than 90% of the studies concluded that supplementing children with vitamin D prevents cavities.
Vitamin D is the name given to a group of fat-soluble prohormones (substances that usually have little hormonal activity by themselves but that the body can turn into hormones). Vitamin D helps the body use calcium and phosphorus to make strong bones and teeth. Skin exposed to sunshine can make vitamin D, and vitamin D can also be obtained from certain foods. Vitamin D deficiency can cause a weakening of the bones that is called rickets in children and osteomalacia in adults. Two major forms of vitamin D that are important to humans are vitamin D2, or ergocalciferol, and vitamin D3, or cholecalciferol.
