Everyone agrees that the number of cavities have plummeted in the U.S. over the last couple of decades, after water fluoridation was introduced (that is why health officials call water fluoridation "one of the ten greatest public health accomplishments of the last century").
That proves that water fluoridation fights cavities, right?
It would, of course, if the cavity levels have not also plummeted in countries which do notfluoridate their water.
Let’s take a look at the scientific literature to get an unvarnished picture on the trends.
Cavity Levels Have Only Plummeted In the U.S. And Other Countries Which Fluoridate Water, Right?
The decline in caries [the scientific term for "cavities"] prevalence in communities without fluoridated water in various countries is well documented. The cause or causes are, at this time, a matter of speculation.
The Journal of Public Health Dentistrynoted in 1985:
Even the most cursory review of the dental literature since 1978 reveals a wealth of data documenting a secular, or long term, generalized decline in dental caries throughout the Western, industrialized world. Reports indicate that this decline has occurred in both fluoridated and fluoride-deficient areas, and in the presence and absence of organized preventive programs.
The prestigious science journal Naturenoted in 1986:
[D]uring the period 1979-81, especially in western Europe where there is little fluoridation, a number of dental examinations were made and compared with surveys carried out a decade or so before. It soon became clear that large reductions in caries had been occurring in unfluoridated areas. The magnitudes of these reductions are generally comparable with those observed in fluoridated areas over similar periods of time
The Journal of the American Dental Association noted in 1988:
The current reported decline in caries tooth decay in the US and other Western industrialized countries has been observed in both fluoridated and nonfluoridated communities, with percentage reductions in each community apparently about the same

Expanding government payrolls have turned the suburbs of Washington, D.C. into some of the most affluent communities in the United States. Under the circumstances, it must have been difficult, these past dozen years or so, for residents to make their way through the city as they headed to a concert or a fine dining spot.

Epizyme was founded in 2007, and trying to create drugs to treat patient's cancer by focusing on genetically-linked differences between normal and cancer cells. Cancer areas of focus include leukemia, Non-Hodgkin's lymphoma and breast cancer. One of the Epizme cofounders, H. Robert Horvitz, won the Nobel Prize in Medicine in 2002 for "discoveries concerning genetic regulation of organ development and programmed cell death."
Before discussing the drug targets of Epizyme, understanding epigenetics is crucial to comprehend the company's goals.
Genetic components are the DNA sequences that are 'inherited.' Some of these genes are stronger than others in their expression (e.g., eye color). Yet, some genes turn on or off due to external factors (environmental), and it is und...

Last fall there was some discussion on the PSW board regarding setting up a YouCaring donation page for a PSW member, Shadowfax. Since then, we have been looking into ways to help get him additional medical services and to pay down his medical debts. After following those leads, we are ready to move ahead with the YouCaring site. (Link is posted below.) Any help you can give will be greatly appreciated; not only to help aid in his medical bill debt, but to also show what a great community this group is.
