Innovative bio-material rebuild teeth structure

Each year, dentists fill cavities in teeth of millions around the world. Usually they meet their job in protecting the pulp from damage, but about 10% of the cases fail. Whereas it is long-lasting and painful root canal treatment removes all infected tissue from the inside of the tooth. It will soon become a thing of the past.

A team of scientists from the University of Nottingham and Harvard University has developed a new bio-material that injected into the tooth allows regeneration of the protective layer of dentin. This behavior prevents another tooth infections and ensures a more integrated and long-term loss of fill.

Existing dental fillings are toxic to cells and are therefore incompatible with a mass of fibrous tissue inside the tooth.

In cases of dental pulp diseases and root of the tooth, usually the perforation is made in order to remove the infected tissue.

We have developed a synthetic biological material that can be used in a similar way to dental fillings, but placed in direct contact with the parts, stimulates the native population of stem cells to regenerate, “said Dr. Adam Celiz from the University of Nottingham.

Synthetic bio-material was created by the British is to stimulate the stem cells in the pulp.

The teeth are made from a variety of tissues. The outermost layer is the tooth enamel, and just below it is the dentin acting as scaffolding. In the Center there is a pulp, soft tissue containing blood vessels and nerve. When tooth decay, bacteria break down tooth enamel, exposing the dentin and increasing the risk of infection of the sensitive pulp.

Thus, even in the event of a failure, tooth rebuilds itself. This new therapeutic technique can completely change the effectiveness of modern dentistry.
