The lowest level of fluoride in drinking water which will cause enamel mottling is:
A- 0.5ppm.
B- 1.0ppm.
C- 3.0ppm. ***
D- 5.0ppm
The use of fluoride as an additive in drinking water has been a hot topic for over 70 years. Although fluoride is naturally found in many water sources, it is often added to water supply systems to provide public health benefits. While the positive effects of fluoride on dental health have been scientifically proven, many citizens are concerned about the effects of fluoridated water on their health and believe that fluoridation is a problem of freedom of choice.
The history of fluoridated water dates back to the early 1900s when Dr. Frederick McKay, a young dentist from Colorado, observed many of his patients in the Pikes Peak area had stained and stoned teeth, known as fluorosis.
However, he noticed that these patients also had fewer cavities than many other patients.
Scientists originally believed the cause was calcium related.
After decades of research, it was finally concluded that runoff from the Pikes Peak rock formations contained large amounts of fluoridated minerals that increased fluoride levels in the region's water supply.
Several studies have been conducted and published, the idea is spread on the health benefits of fluoride when given in appropriate doses.
In the 1950s, experimental programs were introduced to measure the health benefits of artificial fluoridation on drinking water.
These test programs have had great success in preventing tooth decay, leading to widespread acceptance of artificial fluoridation. In 2015, nearly 70% of the US population received fluoridated water.
Fluoride can be added to drinking water in various forms such as fluorosilicic acid, sodium fluorosilicate and sodium fluoride.
Fluoride is also used to fortify certain dental hygiene products such as toothpastes and mouthwashes.
