The Sum of "A Synthetic Enamel for Rapid Tooth Repair", published in NATURE on February 24, 2005
Unlike skins or bones, the tooth enamel, which forms the hard surface of a tooth, does not regenerate itself once damaged. Therefore, the conventional dental treatment includes drilling of the decayed part of a tooth and filling the hole with resin or metal alloy dental materials.

However, such therapy has its limits in the sense that it makes the teeth liable to recur. The problem is that 60% of dental therapy is said to be a retreatment of the tooth once treated, and that is because the dental materials such as resin or metal alloy are totally different from a tooth in composition and structure, and those differences cause tooth decay at the contact point.

The dental therapy by regenerating the tooth enamel rather than drilling the decayed part is the ultimate approach to therapy which every dentist in the world should seek. We have succeeded in developing such therapy of dreams, and we think in the near future this therapy will provide a tremendous decrease in the total incidence of tooth decay by applying it to tooth decay prevention.
