No Evidence That Asthma Leads to Tooth Decay: Study

Posted 19 Sep 2010 by Drugs.com

FRIDAY, Sept. 17 – There's no link between asthma and tooth decay in children, according to a new analysis of studies on the issue. The findings challenge some previous research suggesting that children with asthma may be more likely to develop cavities. For this new study, researchers analyzed 27 studies in papers published between 1976 and March 2010. "We found little evidence to suggest that asthma causes tooth decay. In fact, the two largest studies we reviewed found that children with asthma appear to have fewer cavities than others. This may be because their parents are used to taking them to health-care providers, and routinely bring them to the dentist," study author Gerardo Maupome, a professor of preventive and community dentistry at the Indiana University School of Dentistry, said in a university news release.

Amino Acid May Be Key to Strong Teeth

Posted 22 Dec 2009 by Drugs.com

TUESDAY, Dec. 22 – Scientists have identified the way a simple amino acid makes human teeth strong and resilient. Proline is repeated in the center of proteins found in tooth enamel. When the repeats are long, such as in humans, they contract groups of molecules that help enamel crystals grow. When the repeats are short, such as in frogs, teeth don't have the enamel prisms that provide strength, the researchers explained. The research offers clues on how to engineer tooth enamel. "We hope that one day, these findings will help people replace lost parts of the tooth with a healthy layer of new enamel," lead researcher Tom Diekwisch, professor and head of oral biology at the University of Illinois at Chicago College of Dentistry, said in a news release. But the benefits may extend well beyond teeth. "Proline repeats are amazing. They hold the key to understanding the structure and ... Read more
