Thanks to Paul Lamoreaux of Port Angeles who tracked down the information I needed:
I wanted to know how many kids there are in the US age 12 – 15, because this is the group of which 41% has some degree of fluorosis.
I wanted to show in plain numbers how many kids are affected by each degree of fluorosis severety.
These are the raw figures:
41% of children 12 – 15 years old have fluorosis[1], while 8.6% suffer from moderate fluorosis (white spots and some brown spots with up to 50% of enamel impacted), and 3.6% suffer from moderate and severe fluorosis (white spots and brown spots and sometimes pitting and chalky teeth and 100% of enamel impacted).
How many kids are there in each category. Check my calculations:
| 36,487,082.00 | kids 5-13 years old | ||||
| 16,761,477.00 | kids 14-17 years old | ||||
| 53,248,559.00 | all kids 5-17, a span of 12 years | ||||
| 13,312,139.75 | ages 12-15, a span of 4 years | ||||
| one fourth of all kids 5-17 | |||||
| 5,271,607.34 | 39.600% | unaffected | |||
| 2,622,491.53 | 19.700% | questionable | |||
| 3,793,959.83 | 28.500% | very mild | |||
| 1,144,844.02 | 8.600% | mild | |||
| 479,237.03 | 3.600% | moderate-severe | |||
It is not acceptable to give 479,000 kids nationwide moderate to severe fluorosis. Pro-fluroidationists write off damage to these kids as acceptable loss in return for a dubious slight reduction in caries.
