Through electron microscopy it has been confirmed that the synthetic enamel becomes integrated with existing enamel as if it were one substance.The treatment has been developed by Yamagishi to not only repair existing caries, but also prevent them, as well as whiten dental enamel.

Is there a technology that will improve the properties of enamel?
We now have a technology that hasn’t quite reached the complex hierarchical structure of enamel but is at a level that will be functional and has improved properties when compared to damaged enamel. When will this treatment be available?
Is it possible to form reparative dentine from native dentine compositions?
As of now, scientists have only managed to deliver a reproducible technique that allows them to form a reparative dentine close to native dentine compositions at defect sites translatable to small human lesions.
What is hydrogel enamel?
The team of Prof. Janet Moradian-Oldak fabricated hydrogel, which is a form of synthetic enamel, which is an approach similar to the one by dr Kazue Yamagishi. As she explains in an online interview: We focused on the chemical events that happen outside of the enamel-making cells in order to create enamel.
Biography
Yamagishi Kazue was born in 1891 in Ina City of Nagano Prefecture (died in 1984). When he was 15 years old he became an apprentice for the profession of a woodblock carver to the Yomiuri Shinbun Company, a newspaper company that still exists today. Yamagishi remained with Yomiuri Shinbun from 1906 until 1916. Yamagishi became an outstanding carver.
Yamagishi Kazue as a Carver
Kazue Yamanishi had a high reputation as an excellent carver and often was asked to do the woodblock carving for other artists, among them such illustreous names like Kiyokata Kaburagi, Koshiro Onchi, Hiroshi Yoshida, Paul Jacoulet, Yokoyama Taikan, Takehisa Yumeji and Ishikawa Toraji.
Artworks by Yamagishi Kazue
I think this artist has been a bit neglected. At the time of the first publication of this article we did not have many art works by him in our archive. The watercolors are not really my personal taste. But the woodblock prints, they have a certain appeal and a style that I have not seen with other Japanese woodblock artists before.
How to treat tooth decay?
Tooth decay is normally treated by mechanical removal of the affected part, then filling the hole with a resin or metal alloy. This is less than ideal for tiny early caries lesions as so much healthy tooth must be removed to make fillings stick. A newly developed dental paste of synthetic tooth enamel could avoid that problem.
What is white crystalline paste made of?
The crystalline white paste is made of modified hydroxyapatite, chemically and structurally similar to natural enamel, and it rapidly and seamlessly repairs an early caries lesion by nanocrystalline growth.
What causes hydroxyapatite to grow fast?
The acidic conditions probably contribute to the fast growth of highly crystalline hydroxyapatite by dissociating the calcium phosphate clusters into calcium and phosphate ions 10, 11; the clusters would otherwise slow growth rates and cause low crystallinity. We have shown that our synthetic material can reconstruct enamel without prior ...
What is the second layer of dentin?
Dentin is a tissue that is usually covered by enamel (or some kind of dental fillings) and surrounds the entire pulp. This is the second layer that gets affected if you develop dental caries. In contrast to enamel, your body can grow new layers of dentin (called secondary and tertiary dentin) but it does not happen in the way you may think it does.
Is toothpaste available in 2021?
Initial information on this treatment was published in 2005 in Nature, and toothpaste was announced for 2016 (announcement has been published on dr Kazue Yamagishi’s website, intended for the Japanese market) but as of 2021 it’s still not available and it does not look like it’s going to be in the near future or ever.
Does hydrogel help teeth grow?
Other work regarding regrowing enamel. Hydrogel that can promote the growth of an enamel-like surface on teeth and remineralize the dentin. – by Prof. Janet Moradian-Oldak (Herman Ostrow School of Dentistry at the University of Southern California, Los Angeles, United States)
Is hydrogel good for teeth?
The hydrogel is working on human teeth (which were previously extracted from patient’s mouth) but it’s not clear if the treatment will work just as good inside the human mouth. Another concern that needs to be checked is whether the product is safe so that it can pass all the regulatory steps.
