Lead poisoning may cause dental caries

U.S. researchers said that the higher the blood lead level of children's dental caries are more likely to occur. They said that the United States has more than 200 million children suffer from dental caries, the culprit is likely to lead poisoning.

Dental caries is living in poverty-stricken areas of American children a big problem. So many children are living in the old house, the walls of the brush are extremely high levels of lead paint.

Researchers have confirmed that the lead would result in psychological problems of children. In 1978, the United States banned the use of lead paint. Since the use of lead-free paint greatly reduce the risk of poisoning. However, it is estimated that approximately 57,000,000 painted on the walls of the family is still leaded paint. Lead in old paint and dust in the soil have found.

U.S. Centers for Disease Control and Prevention (CDCP) estimates that nearly 1,000,000 children in the United States in the blood lead level is too high. The latest issue of "Journal of the American Medical Association" published in a dental caries and lead to reveal the relevance of the new study. The new study is the host of the University of Rochester, NY Makemosi study for the 1998-1994 period, involving 25,000 children and adults. The study found that high levels of lead in the blood of the children are more likely to occur and the missing tooth decay.

Mosiboshi said that the incidence of dental caries and blood lead levels in direct proportion. However, some researchers point out that the incidence of caries in addition to lead poisoning in addition to other possible reasons, such as too much sugar in the diet and a lack of drinking water to prevent tooth decay key chemicals such as fluoride. However, Mosiboshi a new study shows that dental caries and the level of lead in the relevance of children and adults in there. However, the researchers said frankly that lead poisoning led to the real mechanism of dental caries is still not clear.

In another new study, researchers at the University of California San Francisco studied the role of vitamin C and lead poisoning. The study included children and adults with a total of 1.9 million people. It was found that whether children or adults, as long as the blood more vitamin C, the blood lead levels on the lower. But the researchers said, "vitamin C to prevent lead poisoning," said the proposal, it would be premature at present.
