Specifically, fluoridated water strengthens teeth both systemically and topically, that is, fluoride ions reach the tooth enamel from within the body and by direct external contact with teeth, while drinking for instance...
...Fluoridation is by far the single most cost-effective way to prevent tooth decay on a large scale," Lawrence says. The cost of maintaining a public fluoridation system adds up to only 10 to 20 cents per person per year, he adds. Installing the new system will cost $1.15 million and annual maintenance will cost $650,000, James Gillis, associate civil engineer for the Water Division of the MDC, says...
Fluoride ions work into the crystalline structure of the tooth surface and make the structure a more perfect and thus more stable crystal. The tooth is therefore less susceptible to decay by acid attack. (Tooth decay is largely caused by acid dissolution of enamel. Acid is a byproduct of food decay...
...tooth-for-tooth warfare snapped a six-week cease-fire along the border that had been arranged by the U.S. The confrontation threatened to snag the slow and painful process by which President Carter hopes to get Israelis and Arabs together at a Geneva peace conference, presumably this year. At his press conference last week, Carter deplored the heavy loss of life, but he declined to single out Israel for striking what had obviously turned out to be civilian targets. "The overriding consideration," the President said, "is not to condemn Israel at this point for retaliation, but just...
...Ethiopia. Two years later their team made an even more dramatic discovery. Not far from their first find, they uncovered the fossilized remnants of a 20-year-old female Australopithecus lying in a layer of sediment 3 million years old. Unlike most other fossils of early man ?a tooth here, a bone fragment there, occasionally a portion of a skull?this one comprised a good part of the skeleton...
