Americans have some tooth decay. In some African areas the figure is as low as 15 percent What could do a better job of shielding American children and adults from tooth decay than is being done by the best toothpastes modern science has to offer? A team of researc hers at Washington university here thinks the answer may tx* hidden in wooden (hewing sticks, widely used in Africa for leaning teeth. Wooden Sticks The team, headed by Dr Memory F’lvin-Lew is, associate professor and chairman of the department of dental microbiology, has done preliminary'research mat indicates the anti-decay substances, known as anti- cariogenics, are found in the wooden sticks The sticks are taken from more than IOO varieties of African plants but they most commonly come from plants in the citrus, ebony and coffee families. Africans using the pencilsized sticks bite them with the tips of the molars, twisting and turning them as they chew on them thoroughly. The end of the stick becomes frayed, and the brushlike area is then used to clean the teeth. The stick is vigorously moved over the surfaces of the teeth, then is often sucked on for hours afterward Some companies in Kngland and India are now using ex tracts from the sticks in commercial toothpaste, but Mrs Elvln-Lewis said the exact chemical substances being released to fight tooth decay have not yet been isolated. To find out, she and her botanist husband, Dr Walter Lewis, along with a team consisting of anthropologists and others, are seeking a grant to go to Ghana and study in more depth the chewing sticks She hopes to find out how they work before more “modern” methods of preventing tooth decay are introduced and obscure the natural potency of the sticks Soil and Water “Our survey would be designed to establish the effect of the sticks on dental hygiene,” she said. “We want to see if there is a direct relationship between low decay and the sticks or whether the soil and water in a particular area are also involved.” Because direct use of the sticks helps the teeth but harms the gums, Mrs. Elvin-I^'wis said the anti-cariogenic substances could be extracted from the sticks and put to use in more conventional methods of dental hygiene. “It’s like doing fluoride research backwards,” she said “Instead of taking 3 sub stance and seeing if it works to prevent decay, we want to see if whatever is in these crewing sticks that prevents decay can be extracted for use in the best possible form.” Whatever is working in the sticks is similar to fluoride, she said, but probably is something more than fluoride She says fluoride is effective, but there is a need for something else “There are vast parts of the world that absolutely refuse to use fluoride,” she said, “This offers a natural alternative ’ GAZETTE TELEPHONE NUMBERS For Nnwv Sports, Bookkeeping, General Infor motion and Offices Not luted Below (all Circulation Subscription Oept Mon thru Sot 8 o rn to 7 p rn Sundays Until I?
