Biological lysozyme toothpaste has not been removed from the shelf. If there is no such product in the user's area, it is because of the supply problem between supermarkets and agents, which leads to the failure to sell biological lysozyme toothpaste on the shelves in some areas. Biological toothpaste refers to a new generation of functional toothpaste with biological lysozyme as the core component. Its "biological lysozyme" is a bioactive protein similar to human saliva lysozyme, which was extracted by gene cloning engineering.
Looking at the research and development of "fe toothpaste", it is a difficult process. In order to fundamentally change the traditional toothpaste, it promoted the upgrading of toothpaste. With the support of the Ministry of Science and Technology and the local government, the Industry-University-Research Cooperative Research Group of fe Toothpaste established by Snow Leopard Company and Fudan University finally successfully developed the world's first bio-enzyme toothpaste.
2065438+04-June 5438+00, fe toothpaste passed the appraisal of scientific and technological achievements of experts from seven institutions, including China Food and Drug Inspection Institute. The appraisal conclusion shows that "this product is the first at home and abroad, and its production technology has reached the domestic leading level". The clinical trials of shanghai journal of stomatology Journal Institute and other institutions show that fe toothpaste has obvious efficacy in solving periodontal and oral problems.
"Because the protagonist of fe toothpaste is biological lysozyme, we advocate dry brushing, that is, dry brushing for 2-3 minutes without dipping in water, so that the active factors of biological lysozyme can be fully exerted and absorbed, and brushing teeth becomes a pleasure. It can be said that fe toothpaste makes it possible for people to solve periodontal health problems by brushing their teeth, which is a milestone for oral health care. " Tong Yu, head of the fe toothpaste research team, said.
No pains, no gains. As early as 2004, iron lysozyme preparation was recognized as a national torch plan project by the Ministry of Science and Technology. In September this year, fe toothpaste became the first recognized high-tech product in the toothpaste industry.
Types of toothpaste
Fluorine toothpaste
It is a kind of toothpaste which has the function of preventing dental caries by adding a proper amount of fluoride into toothpaste. A large number of studies have proved that fluoride can improve the corrosion resistance of teeth and inhibit the growth and reproduction of cariogenic bacteria. A certain amount of fluorine also exists in normal oral environment, but its concentration is not enough to cause the above changes. The use of fluoride toothpaste is to increase the local fluoride in the oral cavity within a safe range and form a solid protective layer on the tooth surface, thus reducing the occurrence of dental caries.
Reminder: Pay attention to the dosage of fluoride toothpaste.
Because children swallow toothpaste, children under 3 should avoid using fluoride toothpaste; Children aged 4-6 should use it under the guidance of adults, and the dosage of brushing each time should be the size of soybean grains.
Xiaoyan toothpaste
On the basis of ordinary toothpaste, some antibacterial drugs are added to reduce inflammation and bacteria, inhibit the formation of dental calculus and plaque, improve the oral environment, and prevent and assist in the treatment of gingival bleeding and periodontal disease.
Reminder: Anti-inflammatory toothpaste should be changed frequently.
Fluorine toothpaste and Chinese herbal toothpaste do not need to be replaced frequently, while anti-inflammatory toothpaste, especially toothpaste with strong antibacterial activity, should not be used for a long time because it may cause oral flora imbalance, and should be replaced every one to two months.
Hypoallergenic toothpaste
Hypoallergenic toothpaste is specially developed for sensitive teeth, which can effectively relieve dentin allergy and enhance the tolerance of teeth to cold, hot, sweet and sour. This toothpaste contains desensitizing ingredients such as potassium nitrate or strontium chloride, which can relieve dentin allergy to some extent.
Reminder: Take temporary solution but not permanent cure.
People with sensitive dentin can choose anti-allergic toothpaste, but this toothpaste is only for mild dentin allergy and can play a certain role in relieving it after use. If it still doesn't work after using it for a while, you need to change a toothpaste.
