Put a "protective cover" on your teeth
The sulcus is closed to protect the teeth. The sulcus and interdental spaces are filled with substances that are not harmful to the body, so as to avoid incomplete brushing, which can cause bacteria to grow in the sulcus and interdental spaces, thereby affecting oral health. It's like putting a protective coat on your teeth to protect them from food.
According to surveys, the incidence of dental caries in deciduous teeth of children aged 5 to 6 years in China is 80% to 90%, the incidence of permanent teeth caries is 48%, and the incidence of caries in the caries is 86%. Therefore, preventing the occurrence of pits and fissures and timely closing the pits and fissures is an important measure for preventing dental caries in children.
How old are children suitable for closure
Zhang Jianqiang, director of the Department of Stomatology of the 304 Hospital of the Chinese People's Liberation Army, said: "The pit and fissure seal is mainly suitable for children with permanent teeth. Large, coupled with the inability to master tooth brushing skills or to brush your teeth carefully. In addition, most children of this age have already entered school and know how to cooperate with doctors. "
Parents question: is it painful to close the ditches?
Ge Lihong, director of pediatrics at Peking University Stomatological Hospital, said: "When closing the furrows, the teeth must be thoroughly cleaned to remove the leftover food residues and bacteria. The method is to clean the teeth with a special rubber cup or brush and then perform acid erosion. So that the surface of the pits and grooves is fine, so that the pit and groove sealant can penetrate into it to achieve the sealing effect, and then the tooth surface is dried to remove the water remaining in the pits and grooves, so as not to affect the curing of the resin and the adhesion to the surface The strength of the joint. Apply a sealant to the pit and groove, and finally use a medical lamp to illuminate the mouth for 10-20 seconds to play a fixed role. "
Medically, the oral cavity is divided into four areas: up, down, left and right. If the children cooperate, the four zones can be completed at one time, and the time is not long, only 20-30 minutes. Director Zhang Jianqiang told reporters that this method is easy to operate and there is no pain. It is only the mouth that needs children to cooperate.
Closed trenches cannot be done once and for all
Director Ge said: The sulcus was closed, but only a layer of "protective clothing" was put on the "tooths". After a period of time, the "protective clothing" would appear to be "damaged" to varying degrees. If you do not pay attention to maintaining the mouth, Inside the sanitation, the life of the "protective clothing" will be greatly reduced, and there is still the possibility of dental caries.
For this reason, Director Ge reminded parents that when they closed the ditches, they should also pay attention to maintaining oral hygiene, and it is best to visit the hospital every six months until the children can clean their teeth autonomously and carefully. At present, professional dental hospitals can generally close the trenches. Some large general hospitals also have this service. Parents can safely take their children to do it.
