New solution to stop tooth rot

07.09.2004


About half of today’s children have tooth decay, so a new solution that blocks the action of bacteria which attack teeth could bring significant benefits, say scientists speaking Monday, 06 September 2004 at the Society for General Microbiology’s 155th Meeting at Trinity College Dublin.



Researchers from the Department of Oral Immunology at King’s College London have discovered how the bacteria which attack teeth, Streptococcus mutans, attach themselves to the enamel surface. Once stuck on, the bacteria convert sugar from our food into acid which then attacks the tooth surface.

“The bacteria use a special protein to recognise teeth, and it fits snugly into their surface like a key fitting into a lock. We have identified the small part of the protein which acts like the key,” says Professor Charles Kelly of King’s College London. “We made identical copies of the small part of the protein, called a peptide, and dripped it onto the teeth of volunteers to see whether it would block up all the possible keyholes, stopping bacteria from attaching to the teeth themselves.”


After three weeks of treatment with the peptide solution the volunteers were monitored for the next three months to see whether any of them became infected with tooth decay bacteria. None of the treated volunteers suffered any tooth decay infection, while other volunteers who received no treatment, or a solution containing a similar but useless peptide, did become infected with Streptococcus mutans.

This study has provided important evidence that a simple peptide could provide a protective solution to tooth decay, by preventing the attacking bacteria from attaching to tooth enamel. Eventually the scientists hope other types of infection might be blocked using the same technique.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

What does it look like below the ice shelf of the calved massive iceberg A68?

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
