Fluoridation of water supplies and cancer mortality. II: Mortality trends after fluoridation.

Cancer mortality by site and fluoridation of water supplies.

Site-specific cancer mortality data for 20 United States cities have been abstracted from United States Government publications to explore further the hypothesis that fluoridation of water supplies causes cancer. Changes in mortality (standardised for age, sex, and ethnic group) between 1958-62 and 1968-72 in 10 fluoridated and 10 non-fluoridated United States cities have been examined. Of the ...

Fluoridation of Drinking Water and Subsequent Cancer Incidence and Mortality

Fluoridation of water supplies and cancer mortality. III: A re-examination of mortality in cities in the USA.

Differences in trends in crude mortality rates from cancerbetween 10 fluoridated and 10 non-fluoridated cities in theUSA were claimed by Yiamouyiannis and Burk to indicate that cancer mortality had risen to an unusual extent in the fluoridated cities.' 2 These claims, which were widely publicised, prompted us, among others, to examine all relevant published data for the cities in question. When...

Fluoridation and cancer mortality in Anglesey.

Mortality in Anglesey from cancer (all sites), cancer of trachea, bronchus, and lung, cancer of stomach, and cancer of all other sites has been compared with mortality in England and Wales at two periods; 1949-53 (before fluoridation) and 1979-83 (after 20 years and more of fluoridation). No evidence has been found to support the hypothesis that water fluoridation affects cancer mortality.

Water fluoridation.

AIM This was to present a summary of the evidence from systematic reviews of the effectiveness and safety of water fluoridation. METHODS A search for relevant systematic reviews was conducted using the terms Fluoridation [Mesh] OR "water fluoridation" OR fluoridation OR (water AND fluoride) and was run from 01/01/2000 to 17/10/2008 in Pubmed, Embase, the Cochrane Database of Systematic Review...
