[Longevity of a population exposed to fluorides for decades]

Among a population with considerable fluor exposure lasting for decades and that of the corresponding district the proportion of older persons was compared per cent. In the five-year groups from 70 to 89 years without any exception a prevalence in favour of the place with fluor load was found. Cumulatively significant differences in favour of the population under influence of fluor was found. The possible causes for the suggested connections between fluor effect in the organism and obtaining of older ages are represented.
