Abstract

The invention relates to the applying method of nanometer calcium acid phosphate salt in toothpaste which belongs to the application technology domain of nanometer biological material in medicine. The salt with a size of is 20-500nm can be adhered to toothpaste; or 0.2-25% part (by weight) salt with a size of 20-500nm can be added to the toothpaste. The material can be adhered and deposited in the dental caries micro cavities because of the great ability of adherence and ionic dissociation of nanometer materials. The ion then liberated, when the density of [Ca2+],[PO43+],[OH-] is large enough, they will re-mineralize. When there is medicine in toothpaste, it also has the function of delayed release. The invention is mainly applicable to toothpaste making domain.

Description

technical field [0001] The invention belongs to the technical field of application of nano biomedical materials in toothpaste. Background technique [0002] At present, dental caries is the second largest high-incidence disease after tumors in the world. One of the methods for people to prevent dental caries is to add anti-caries drugs to toothpaste. With the continuous development of science and technology, material science and medicine continue to intersect, and the branch of biomedical materials has emerged. Meng Xiangcai of Jiamusi University and others first applied nano-hydroxyapatite to toothpaste and mouthwash in China, and found that it has dental caries regeneration. Mineralization, and apply for a two-phase patent. [0003] The preparation process of nano-hydroxyapatite makes it difficult to carry out industrial production, and its synthesis cost is high, which limits its application in the field of toothpaste. Nano-calcium phosphate is very similar to nano-hydr...
