After the Fall of Saigon in April 1975, the company merged with Kolperlon, another local toothpaste company, to became Orchid Toothpaste Factory. [7] Orchid became Vietnam's first state-owned enterprise on May 30, 1975. [4] [8] At the time, the company produced 80 000 tubes of toothpaste per day, using locally sourced calcium carbonate. [8]
Fluoride is present in small amounts in plants, animals, and some natural water sources. The additional fluoride in toothpaste has beneficial effects on the formation of dental enamel and bones. Sodium fluoride (NaF) is the most common source of fluoride, but stannous fluoride (SnF 2), and sodium monofluorophosphate (Na 2 PO 3 F) are also used ...
Fluoride therapy is the use of fluoride for medical purposes. [2] Fluoride supplements are recommended to prevent tooth decay in children older than six months in areas where the drinking water is low in fluoride. [3] It is typically used as a liquid, pill, or paste by mouth. [4] Fluoride has also been used to treat a number of bone diseases. [5]

Other fluoride therapies are also effective in preventing tooth decay; [29] they include fluoride toothpaste, mouthwash, gel, and varnish, [94] and fluoridation of salt and milk. [93] Dental sealants are effective as well, [29] with estimates of prevented cavities ranging from 33% to 86%, depending on age of sealant and type of study. [94]
Topical fluorides are fluoride-containing drugs indicated in prevention and treatment of dental caries, particularly in children's primary dentitions. [1] The dental-protecting property of topical fluoride can be attributed to multiple mechanisms of action, including the promotion of remineralization of decalcified enamel, the inhibition of the cariogenic microbial metabolism in dental plaque ...
Water fluoridation is the controlled addition of fluoride to a public water supply to reduce tooth decay, and is handled differently by countries across the world. [2]Water fluoridation is considered very common in the United States, Canada, Ireland, Chile and Australia where over 50% of the population drinks fluoridated water.
[22] [56] Studies in the U.S. in the 1950s and 1960s showed that water fluoridation reduced childhood cavities by fifty to sixty percent, while studies in 1989 and 1990 showed lower reductions (40% and 18% respectively), likely due to increasing use of fluoride from other sources, notably toothpaste, and the "halo effect" of food and drink that ...
