How to protect our teeth
Starting from June 1 this year, 200000 school-age children aged 6 to 8 in Beijing will go to some hospitals for pit and fissure sealing of "six age teeth", and each tooth will enjoy a subsidy of 5 yuan from the government, for which the government will pay 4 million yuan. It is understood that pit and fissure sealing is an effective method to prevent dental caries in the world. However, in Beijing, only less than 10% of school-age children have done pit and fissure sealing. The main reason for this situation is that parents lack the understanding of preventing dental caries and pit and fissure sealing.
How do parents view their children's dental health and pit and fissure sealing? Recently, the reporter conducted a sample survey on 60 parents of students in grade one, three and five in Sanlitun No.1 Primary School in Chaoyang District of Beijing. The results showed that 32 parents thought that their children's teeth were healthy and there was no need to go to the hospital for examination, accounting for 53.3% of the total number; 47 parents did not know what pit and fissure sealing was, accounting for 78.3%; 38 parents thought that pit and fissure sealing had little effect on preventing dental caries, accounting for 63.3%; There are 51 parents think it is unnecessary to let their children do pit and fissure sealing, accounting for 85%
From the above survey results, it can be seen that most parents do not know what pit and fissure sealing is, and think that it is unnecessary to go to the hospital to see the dentist when the child's teeth are healthy. Ms. Zhao, the mother of fan Yingjun, a first-year student in Sanlitun primary school, said: "I always pay attention to the habit of carefully brushing my children's teeth in the morning and evening, and usually pay great attention to their diet, so that she can eat less sweet food. A dentist in the neighborhood said, "Yingjun's teeth are OK. There's no need to seal the pit and fissure."
Some parents think that the child is changing teeth, now to do pit and fissure sealing for deciduous teeth is white, it's better to wait until the child's teeth are all changed. Meng Zhangming, the father of Meng Zhaoan, a third grader in Sanlitun primary school, said: "I'm so old, I've never done anything, and my teeth are good. No matter what's going on with pit and fissure sealing, I don't want my children to do it."
-Noun explanation
Pit and fissure sealing
In the early stage of eruption of children's permanent teeth, the surface of permanent teeth is treated and then applied with pit and fissure sealant to make it penetrate into the fissure area of teeth, solidify with the mineral tissue of teeth, fill the fissure, isolate the invasion of cariogenic substances on teeth, and achieve the effect of preventing dental caries.
If children cooperate, the whole process only takes 20 to 30 minutes, and because the tooth tissue is not removed, there is no pain in pit and fissure sealing. If the pit and fissure sealant does not fall off, its caries prevention effect can reach more than 90%.
-Expert opinion
Pit and fissure sealing can effectively prevent dental caries
Liang Li, director of Dental Prevention Institute of Haidian District, Beijing
The masticatory surface of children's deciduous molars and permanent molars is uneven, there are some natural pits and fissures, dental plaque and food residues are easy to accumulate in these parts, and brushing teeth is difficult to clean up, over time, pit and fissure parts will have caries, which is often called pit and fissure caries. According to the statistics of the national dental office, the rate of caries of children's permanent teeth is 48%, and the incidence rate of dental caries is 86% of the incidence of dental caries.
At present, the most effective way to prevent pit and fissure caries is to use pit and fissure sealing method, which can block the invasion of new bacteria and the reproduction of old bacteria. Therefore, parents should understand that it is necessary to let their children do pit and fissure sealing.
Moreover, at present, the cost of a pit and fissure sealant in Beijing is no more than 30 yuan, and after a tooth has a problem, the cost of treatment is generally between 300 yuan and 500 yuan. There is a gap of more than 10 times between the two. It can be seen that the pit and fissure sealant is much more affordable from an economic point of view.
Generally speaking, within one year after eruption of molars, the best effect is to let children do pit and fissure sealing, because the newly erupted teeth have insufficient surface calcification, poor acid resistance, and are prone to caries, so preventive measures should be taken as soon as possible. Moreover, the pit and fissure on the surface of newly erupted teeth are deep, the sealant is not easy to fall off, and the caries prevention effect is the best, It's no use doing pit and fissure sealing again. Therefore, parents should deepen the understanding of dental caries and pit and fissure sealing, and make the right choice for their children.
-Suitable for people
Primary molars and permanent teeth should be closed
Zhu Hong, director of the stomatology department of Beijing Children's Hospital, said that pit and fissure sealing is suitable for children in the following situations: first, children aged 3 to 4 should seal their deciduous molars. Deciduous molars erupt at about 3 years old and replace at about 11 years old. They stay in the oral cavity for a long time and play an important role. They should be closed.
Second, children aged from 6 to 8 closed their sixth age teeth. The sixth age teeth erupt around the age of 6, which is the earliest permanent teeth in the oral cavity. It is also the most important four teeth that play the masticatory function, affect the tooth arrangement and maxillofacial development, and must be protected.
Third, for children aged 11 to 13 years old, bicuspid teeth and second permanent molars just erupted, and the effect of pit and fissure sealing was the best.
-Precautions
Review every six months
After the pit and fissure are closed, don't eat walnut or chewing gum within 24 hours. After a week of running in, you can eat at will.
Due to various reasons, after the pit and fissure sealant is finished, it may lead to insufficient fit between pit and fissure sealant and tooth surface, or even fall off. So after finishing every six months to the hospital review.
If in doing pit and fissure sealing, the doctor found that pit and fissure deep, or tooth pigment changes (signs of early caries), it should be done, every three months to the hospital review.
Although there is no pain in doing pit and fissure sealing, the child will still have fear when doing the first tooth. Parents should cooperate with the doctor to appease the child. Generally from the second tooth, the child's fear completely disappeared.
