Assignment
Fluorosis first attracted attention in the early 20th Century. Researchers were surprised by the high prevalence of what was called "Colorado Brown Stain" on the teeth of native-born residents of Colorado Springs. The stains were caused by high levels of fluoride in the local water supply. This was fluoride that occurred naturally in the ground water. People with these stains also had an unusually high resistance to dental cavities. This sparked a movement to introduce fluoride into public water supplies at a level that could prevent cavities but without causing fluorosis.
