Summary
1. Thirty-nine pharmaceuticals prescribed by obstetricians and pediatricians were analyzed
for micro quantities of fluoride for this report,
2. Effect of ingestion of occult fluoride on cord blood and placenta is referred to,
3. Cause of "idiopathic opacities" of enamel and enamel hypoplasias occurring in fluoride free or "optimum supplied'' water supplies is suggested.
Ingestion of fluorides for the partial prevention of dental caries has been suggested for some time, wit

On June 20th, 1955, Brantford completed ten years of experience with mechanically fluoridated water.
Earlier reports (1) have shown that the full decay-preventing effect of the fluoridated water on the permanent dentition of the Brantford children began to show itself in 1951, when the first permanent molars appeared in the mouths of the children born there in 1945. In 1953, after these teeth had been exposed in the mouths of the eight-year-old children for a period of two years out r

The purpose of this report is the review of the present knowledge of the metabolism of fluorides, particularly in the human body, and the use of this knowledge in estimating the factors of safety in water fluoridation. In this discussion, many of the biological effects of fluorides (purported or well-established) will receive no mention. On the other hand, there are a few important biological effects of fluorides so well studied that there is an established relation between the effect a
The onset of menstruation in girls was selected as an index of the rate of sexual maturation, since the menarche is an event which is usually readily dated. The distribution of ages at the nearest birthday at which menstruation first occurred is shown in Table 5. The average age at the menarche was 12 years among the girls studied in Newburgh and 12 years 5 months among the girls in Kingston. No statistical significance could be demonstrated in this difference, nor in the difference between the

In areas where the potable water supplies contain the fluoride ion at optimum concentration at the source, the dental caries experience of children who ingest these water fluorides during the years of tooth development is about 60 per cent less than among children in areas with fluoride deficient water supplies.1 Adults who have used such water supplies continuously enjoy the dental benefits obtained during childhood.2
