Yamagishi. It’s about a new toothpaste that fills all the holes
and cracks in the teeth and restore the tooth enamel.

its composition the tooth paste of the Japanese researcher is similar with the
tooth enamel, the only difference is that it is liquid. Thus it can
easily be applied to the affected area with a toothbrush.
The formula of the new paste is obtained after a
series of experiments with hydroxylapatite, also called crystalline calcium
phosphate, the main component of the tooth.
"A toothpaste has been
developed that can rapidly and seamlessly fix little cavities without need for
paste of synthetic tooth enamel could revolutionise treatment of tiny early
lesions, says the study published today in the journal Nature by Dr Kazue
Yamagishi, of the FAP Dental Institute, Tokyo.
Tooth decay is
normally treated by removal of the affected part, then filling the hole with a
resin or metal alloy. This is less than ideal because a lot of healthy tooth
must be removed to make the fillings stick.
Dr Yamagishi and
colleagues developed a crystalline white paste of modified hydroxyapatite,
which is chemically and structurally similar to natural enamel, and used it to
repair early damage to a lower premolar tooth.
An electron microscope
showed that the natural and artificial enamel became integrated as if they were
the paste is applied to the teeth, the acid on the surface of the teeth begins
to dissolve. Three minutes later, the paste begins to crystallize and gets
fastened to the structure of the natural enamel.
