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

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.
Last week brought even more stock market weakness and volatility as the selloff became self-perpetuating, with nobody mid-day on Wednesday wanting to be the last guy left holding equities. Hedge funds and other weak holders exacerbated the situation. But the extreme volatility and panic selling finally led some bulls (along with many corporate insiders) to summon a little backbone and buy into weakness, and the market finished the week on a high note, with continued momentum likely into the first part of this week.
Despite concerns about global economic growth and a persistent lack of inflation, especially given all the global quantitative easing, fundamentals for U.S. stocks still look good, and I believe this overdue correction ultimately will shape up to be a great buying opportunity -- i.e., th...
Following last year's 20,000 word "decision" at the 3rd Plenum pledging reforms, soft-landings, and corruption crackdowns, we thought we'd leave it to China's state-owned media to explain - via handy infographic - what to expect from the 4th Plenary session this week...
It's time again for my weekly gasoline update based on data from the Energy Information Administration (EIA). Rounded to the penny Regular dropped another nine cents and Premium eight cents. Regular is now at its lowest price since January 2011.
According to GasBuddy.com, only one state (Hawaii) has Regular above $4.00 per gallon. The highest continental average price is in California at 3.49. Missouri has the cheapest Regular at $2.76.
How far are we from the interim high prices of 2011 and the all-time highs of 2008? Here's a visual answer.

What do falling energy prices mean for the US consumer? Sober Look writes a brief yet thorough overview of the consequences of the correction in the price of crude oil. There are good aspects, particularly for the consumer, bad aspects, and out-right ugly possibilities. For more on this subject, read James Hamilton's How will Saudi Arabia respond to lower oil prices? In previous eras, Saudi Arabia would tighten the supply to help increase prices, but in this "game of chicken," the rules m...
Shares in Apple (Ticker: AAPL) are near their highs of the session in the final hour of trading on Wednesday, adding to the muted gains seen earlier in the day, following the release of the September FOMC meeting minutes and after activist investor and Apple shareholder Carl Icahn tweeted, “Tmrw we’ll be sending an open letter to @tim_cook. Believe it will be interesting.” Icahn’s tweet hit the ether at 2:33 pm ET and was met with a spike in volume in Apple shares. The stock is currently up 2.0% on the day at $100.75 as of 3:15 pm ET.

Well PSW Subscribers....I am still here, barely. From my last post a few months ago to now, nothing has changed much, but there are a few bargins out there that as investors, should be put on the watch list (again) and if so desired....buy a small amount.
First, the media is on a tear against biotechs/pharma, ripping companies for their drug prices. Gilead's HepC drug, Sovaldi, is priced at $84K for the 12-week treatment. Pundits were screaming bloody murder that it was a total rip off, but when one investigates the other drugs out there, and the consequences of not taking Sovaldi vs. another drug combinations, then things become clearer. For instance, Olysio (JNJ) is about $66,000 for a 12-week treatment, but is approved for fewer types of patients AND...
