Bees produce a powerful composite anti caries

Dentists Medicine Center at the University of Rochester, New York, together with scientists in biology and nutrition at the University of Caminos, Brazil, discovered that a compound produced by Brazilian bees to build, repair and protect their beehives could be a powerful anti-caries agent.

This is the propolis, a sticky element that bees used to give consistency to their hives. The secretions produced from trees and other plants, which are transported to the nest, chewed and returned, and then mixed with wax themselves also produce. In the honeycomb, the substance is used to seal holes and openings, keep clean, and up to embalm dead insects.

In laboratory tests the most powerful version of this compound, made by bees in southern Brazil, decreased the incidence of caries in rats by 60%, and virtually ended the activity of an enzyme ( "GIF") key the formation of plaque. Based on the fact that rats develop caries in the same way as humans, and some substances that prevent cavities in humans also do so in animals, researchers are declared very excited by the potential shown by this compound to prevent decay in people. Now need to test its action in human volunteers.

The relationship between some components of the honeycomb material and dental health was first discovered by Dr. Michel Hyun Koo, a graduate in Brazil and further studies in Nutritional Biochemistry. His persistence led him to investigate these properties of these substances, focusing on the anti caries potential of propolis while getting his degree in nutritional sciences and a Ph.D. in oral biology in Brazil. He then moved to the Center for Oral Biology, University of Rochester to develop their research on the subject.

But not all propolis are equal. Its effectiveness depends greatly on the type of plants and trees in the area where the bees do their homework. Koo over 2,500 samples analyzed only in Brazil. Therefore, the mere presence of propolis in a product does not necessarily effective.

Koo has spent thousands of hours of work in his laboratory in Rochester working with Dr.

William Bowen, trying to identify which of the 100 components of propolis are

Holders of anti caries properties. So far have identified two, both from the potent propolis made by bees in southern Brazil.
