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

Mullah Omar, the dreaded supreme leader of Afghan Taliban, died two years ago from Tuberculosis, Pakistan told Afghan government officials. Afghan news agency the Khaama Press said Mullah Omar's death was discussed during a meeting of Afghanistan cabinet after Pakistani authorities confirmed the reports.
Though Pak authorities said Mullah Omar died two years ago, they did not provide further details regarding the circumstances surrounding his death. The Afghan Taliban has not officially confirmed the reports, but a representative told BBC News that the militant group would issue a statement shortly. A current council member and a former Afghan Taliban ...
Economists were shocked by the plunge in the Conference Board Consumer Confidence Index this morning, well below the any economist's guess in Bloomberg's Econoday Forecast. The consensus estimate was 99.6. The consensus range was 97.0 to 102.0. And the actual result ... 90.9.
Consumer confidence has weakened substantially this month, to 90.9 which is more than 6 points below Econoday's low estimate. Weakness is centered in the expectations component which is down nearly 13 points to 79.9 and reflects sudden pessimism in the jobs outlook where an unusually large percentage, at 20 percent even, see fewer jobs opening up six months from now.
A striking negative in the report is a drop in buying plans for autos which conf...
Big gains and a strong reversal in the Russell 2000 puts a potential bottom in play. The Russell 2000 started the day below the 200-day MA, but then rallied to claim a spike low and a close above this key moving average. Small Caps are a key driver in trend cycles. The 'bull trap' from June is still dominant. and a push above 1,280 looks a tall order. but reversing the breakdown of the rising trendline at 1,240 is a different proposition. If it fails at this, then a swift return below the 200-day MA, and then some, opens up. And the long awaited intermediate term decline begins.
The S&P gained over 1% with a second bounce off the 200-d...

Back in December, I wrote a post on my blog where I compared the performances of various ETFs related to the oil industry. I was looking for the best possible proxy to match the moves of oil prices if you didn't want to play with futures. At the time, I concluded that for medium term trades, USO and the leveraged ETFs UCO and SCO were the most promising. Longer term, broader ETFs like OIH and XLE might make better investment if oil prices do recover to more profitable prices since ETF linked to futures like USO, UCO and SCO do suffer from decay. It also seemed that DIG and DUG could be promising if OIH could recover as it should with the price of oil, but that they don't make a good proxy for the price of oil itself.

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.
