New Discovery to Help Tooth Enamel Damage

A novel discovery that may help in repairing damaged tooth enamel has been made by scientists from University of Illinois at Chicago.

They have found that a simple amino acid that is repeated in the centre of proteins found in tooth enamel makes teeth stronger and more resilient.

Scientists Develop Toothpaste That Rebuilds Tooth Enamel
British scientists have developed a toothpaste that they claim contains a liquid form of calcium and can help in treating sensitive teeth by rebuilding the tooth enamel.

The research team compared proline repeats in amphibian and animal models and discovered that when the repeats are short, such as in frogs, teeth will not have the enamel prisms that are responsible for the strength of human enamel.

In contrast, when the proline repeats are long, they contract groups of molecules that help enamel crystals grow.

"Proline repeats are amazing," said Tom Diekwisch, professor and head of oral biology in the UIC College of Dentistry and lead researcher on the study.

Tooth Enamel Eaten Away By Popular Drinks
The high acid content in popular drinks could just be sufficient enough to erode tooth enamel and cause dental damage, suggests a new study conducted by researchers at University of Iowa.

"They hold the key to understanding the structure and function of many natural proteins, including mucins, antifreeze proteins, Alzheimer amyloid, and prion proteins.

"We hope that our findings will help many other important areas of scientific research, including the treatment of neurodegenerative diseases," he added.

Orange Juice Do More Harm To Teeth Than Whitening Products
Orange juice and other acidic fruit juices are more harmful for teeth than using whitening products, according to researchers at Eastman Institute for Oral Health.

The new discovery, Diekwisch said, will give new clues 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," he added.

What Makes Our Teeth Resilient to Wear and Tear
Despite all the crunching and munching at every meal, our teeth remain stronger to go under some more tests each day, and now researchers have attributed this resilience

The findings are published in the Journal PLoS Biology.
