While this system works well for individual level interventions, its application is more problematic when it comes to public health interventions such as water fluoridation
because most of the study designs included in the reviews, such as controlled before/ after studies and cross-sectional studies are not included in the hierarchy of evidence.
The definitive British study into fluoridation
was the Systematic Review carried out by the Centre for Reviews and Dissemination (CRD) at the University of York.
However, since both the State and the City are bankrupt, the actual fluoridation
was slowly instituted starting in the north and now funds were being made available to fluoridate water all the way to the San Diego area.
Up to pounds 14m extra funding will be made available over the next three years by the Government to those Strategic Health Authorities who, following consultations, find the local community is in favour of the introduction of fluoridation
Well, he will find plenty of highly voluble, expert and experienced doubters who in recent years have become used to winning fluoridation
arguments, rather than being browbeaten and bullied by the medicopolitical establishment.
Welsh secretary of the British Medical Association Dr Richard Lewis said the doctors' group had been in favour of the fluoridation
of mains water supplies for many years.
Last week, 630 medical professionals including one Nobel prize winner, doctors, dentists, pharmacists and researchers practising worldwide, signed a statement condemning compulsory water fluoridation
Kamini Shah, a consultant in public health for 10 PCTs in County Durham and the Tees Valley, said other boroughs like Hartlepool benefit from the natural fluoridation
But the Government ignored the findings and, in the 2 00 3 Water Bill, they introduced legislation to extend water fluoridation
In the United States, several agents are used for fluoridation
, including silicofluoride compounds (sodium silicofluoride and hydrofluosilicic acid) and sodium fluoride.
I see the gloves are on for the next round of the fluoridation
fight (The Journal, November 8).
A 1991 study by the Public Health Service credited fluoridation
with reducing cavity rates by 20 to 40 percent.
