1. Fluoride can inhibit the growth, reproduction and acid-producing ability of cariogenic bacteria and reduce the occurrence of dental caries.
2. Fluorine can be firmly combined with teeth, so that teeth are not easy to dissolve even in acidic environment, and the caries prevention ability of teeth is enhanced.
3. Fluoride can also promote tooth remineralization and make teeth with early caries self-repair.
4. Fluorine can change the shape of teeth, which is beneficial to self-cleaning and not easy to get dental caries.
Second, what is the fluorine protector?
Fluoride protective paint is a kind of paint or liquid obtained by dissolving fluoride in ethanol on the basis of nature or synthesis. The fluoride commonly used now is sodium fluoride. Since the advent of fluorine protective paint, as an effective caries prevention method, it has been widely welcomed in many countries, especially in Europe. In recent ten years, many clinical trials have shown that compared with the untreated control group, the reduction rate of permanent tooth caries after fluoride coating treatment is 60~70%.
Third, common brands.

3M experts answer!
1. How to control the dose of fluoride applied to children?
Answer: 3M tetrafluorone protective paint with 0.5ml independent small package is clean and hygienic;
For deciduous dentition patients or those with only a few tooth surfaces or cavities to be coated, the maximum dose is 0.25m l；; ;
For patients with mixed dentition or patients with many tooth surfaces or cavities to be coated, the maximum dosage is 0.40ml；;
For patients with permanent dentition or patients with many tooth surfaces or holes to be coated, the maximum dose is 0.50 ml.
2. Can only 0.25ml fluoride be applied to deciduous dentition? It is impossible to cover all the teeth.
Answer: For deciduous dentition, the maximum dosage of 3M fluoride protective paint is 0.25ml Because of its good permeability, it is not necessary to cover all tooth surfaces, and good anti-caries and anti-sensitivity effects can be achieved through penetration.
What is the concentration of 3.3M fluorine protective paint?
Answer: The effective components of 3M tetrafluoride protective paint are modified tricalcium phosphate and fluorine, and each individual package contains 0.5ml of fluorine 1 1.3mg, and the effective F concentration is 22,600 ppm. After coating, saliva activates the modified tricalcium phosphate, dissolves the protective film, releases Ca and P, and reacts with F to form more acid-resistant fluorapatite on the tooth surface, thus promoting tooth remineralization.
4. If the child has no dental caries, can he apply fluoride protective paint? How often do you paint it?
Answer: Fluoride protective paint is mainly used for prevention and treatment, and it is suitable for low fluorine area or suitable fluorine area (F concentration is 0.8~ 1ppm), so it will not cause dental caries, so it is necessary to pay attention to the corresponding dosage; Many dentists suggest applying once every six months, but if dentists assess that children are at high risk of caries (DMF >: 1), it can be increased to once every three months.
5. After the deciduous teeth are filled, do you still need to apply fluoride?
Answer: the filling of deciduous teeth indicates that dental caries have occurred. It is recommended to apply fluoride and pay attention to the dosage. The maximum dosage of 3M Lefron deciduous teeth protective paint is 0.25ml.
6. If fluorine is used locally, is it necessary to detect the concentration of fluorine in water?
Answer: The fluorine concentration of qualified drinking water is about 1ppm, and it is high fluorine above 4ppm. If you live in a high fluorine area, you need to use fluorine carefully and pay attention to prevent excessive intake of fluorine.
7. How old can I stop fluoride coating?
Answer: not based on age, but on the risk of caries. Children have a higher risk of dental caries because they don't master the methods of maintaining oral hygiene, but this doesn't mean that adults don't have the risk of dental caries. Adults at high risk of dental caries are also advised to use fluoride every 3-6 months. You can ask your dentist how to assess the risk of dental caries.
8. How often is it better for patients with acid corrosion to apply fluorine protective paint?
A: It is recommended to apply fluoride once every three months.
9. How old can children use fluoride toothpaste?
A: For children with dental caries, toothpaste containing F can be used at any age, and the dosage should be reasonably controlled according to the manufacturer's instructions. 3M Comeno Toothcream (F concentration 950ppm) is suitable for children and adults over 2 years old.
10. Children's toothpaste contains low fluorine and high fluorine. How to choose?
A: According to the national toothpaste standard (GB8372-2008), the fluoride content of children's fluoride toothpaste is between 400 ppm- 1 100 ppm. Toothpaste for children with fluorine content below 400ppm belongs to ordinary toothpaste, toothpaste with fluorine content between 400ppm and 1 100ppm belongs to functional toothpaste, and toothpaste with fluorine content above 1 100ppm is not recommended for children.
1 1. What is the dose of fluorosis?
A: Plasma fluoride concentration of 850ng/ml may cause fluorosis. The plasma fluoride concentration of normal use of fluoride protective paint is about 180ng/ml, and the standardized use will not cause fluorosis. The dose of acute fluorosis is 5 mg/kg body weight.
3M Xerox fluoride protective paint will not cause acute fluorosis according to the standard dosage.
Primary tooth stage: 0.25ml=5.65 mg fluoride at most.
Mixed dentition: 0.4ml at most, equivalent to 9.04 mg fluoride.
Maximum permanent dentition: 0.5ml, equivalent to 1 1.3mg fluoride.
When there is an accident of excessive fluoride intake, don't try to spit out the excessive fluoride intake, but drink 1-2 cups of milk first and send it to the doctor in time.
12. Some children have finished correcting, but there is obvious mineral deficiency on the tooth surface. How to deal with this situation?
Answer: If it is limited to demineralization, fluorine protective paint can be applied regularly to promote remineralization; If there is a substantial defect, it needs to be repaired after caries removal, and fluoride should be applied regularly after repair; It is suggested that fluoride should be used every 3~6 months during the whole orthodontic process.

Please read the following carefully.
Fluoride can prevent dental caries, which is the greatest contribution of preventive stomatology to mankind in the 20th century. Fluorine exists widely in nature, and human body can ingest fluorine from drinking water, food and air. Fluoride caries prevention can be divided into systemic application and local application. The most common way to use fluoride locally is to brush your teeth with fluoride toothpaste and apply fluoride regularly and professionally.
Doctors usually choose the appropriate fluorinating agent and cleaning method according to each child's age, degree of cooperation and other specific conditions, and according to the child's susceptibility to dental caries. It is recommended to review every 3 months, 6 months or 1 year.
Please take the initiative to inform the doctor of the following situations: if the patient conceals the medical history and causes adverse consequences, the patient shall be responsible for it.
1. Drug and anesthesia allergy and surgical history.
2. The latest application of fluoride preparation.
Precautions after operation:
1. The dosage of fluoride preparation is different for children of different ages. Not only is the dosage large, but the effect is good. The doctor will control the dose
2. The application scope of fluoride preparation is mainly aimed at the parts with high caries rate, such as lip surface, adjacent surface and articular surface, and the caries probability of palate and tongue surface is low, and the comfort of children is poor after coating, so it is generally not applied.
3. Fluoride preparations will form a fragrant film when encountering saliva, and children may have reactions such as excessive saliva, repeated licking or crying, which is a normal reaction. Parents don't have to worry.
4. Water is forbidden for half an hour after fluoride preparation is applied, and no food is allowed within 4 hours. Children can drink water through straws when they are thirsty, and eat semi-liquid or soft food when they are hungry. After 24 hours, he can brush his teeth and remove the film and white plaque on his teeth.
