Scientists were able to first grow tooth enamel

What do you think, what is the most durable fabric in our body? Almost certainly the first thing that comes to mind - it's bone. After all, they are really very strong. Bones "hold" on himself the whole muscular frame and protect the internal organs. Without doubt, the bone is very strong, but we also have something poprochnee - teeth, or to be more precise, the tooth enamel. Hardness and strength it is unmatched by any bone, but have enamel and huge drawback: after injury, she is not able to regenerate. However, a team of scientists from China has been able to solve this problem and raised enamel in the laboratory. And the enamel is no worse than the "real".

Tooth enamel - the most durable material in the human body

How to restore the enamel?

According to the publication Science Advances, a group of researchers at the University of Zhejiang led by Dr. Liu Zhaoming developed a special gel which assumes after curing properties and durability comparable to those of conventional dental enamel.

Tooth enamel is formed when the biologically fetal development, but after ripening it becomes acellular and thus loses the ability to heal itself. As a result, cavities or other dental damage completely destroy the structure, so the cavity to restore its functionality has not come out. - says Dr. Liu Zhaoming.

In fairness it should be noted that attempts to recreate the tooth enamel made earlier. About these investigations we often write on our website in Yandex. Zen, so we recommend to subscribe in order to be aware of. However, the main problem in these investigations is the difficulty in synthesis of clusters of calcium phosphates. These are the basic "building blocks" of the tooth enamel, which due to the composition and the form and give it its properties. In itself, the substance calcium phosphate is not difficult to create. It is difficult to "pack" it in such a way that turned out, roughly speaking, a high content of this substance in a small space. And a group of Chinese researchers have succeeded.

They were able to obtain clusters of calcium phosphate with a diameter of 1 to 5 nanometers. But this figure is as close to that of natural enamel. Fully gel technology development, scientists are not currently open, but they were told that in order to achieve such results, they used triethylamine, a substance that slows down the "sticking" conglomerates of calcium phosphate, which allows them more tightly "packed". Artificial tooth enamel is connected with a human tooth. Blue is the natural enamel, green - artificial

At the same time, scientists have conducted the first experiments on the damage to the human teeth, which were removed and stored in a solution that evokes the humidity, temperature and other conditions that are inherent in the human mouth. The illustration above shows that good enamel "survives". According to scientists, the full implantation of artificial enamel took about 48 hours. But there is a small problem. The fact that the gel was able to create only the layer thickness of only about 3 micrometers. This is about 400 times thinner than the enamel intact. However, experts do not lose heart, and now started experiments on mice in order to improve performance of the new gel. Once this is achieved, there will be a testing phase synthetic enamel on patients of dental clinics.
