Question 1: What does pit and fissure closure mean? What kind of pit and fissure sealant is also called pit and fissure sealant, which refers to the method of coating a layer of adhesive resin on the occlusal tooth tissue without removing it, protecting the enamel from bacteria and metabolites, enhancing the ability to resist dental caries, and thus achieving effective dental caries prevention. The pit and fissure sealant forms a protective barrier to prevent bacteria and food residues from entering the pit and fissure, and at the same time, the original bacteria in the pit and fissure gradually die because of cutting off nutrition, thus preventing the occurrence of pit and fissure caries and preventing the development of early caries.

Who needs pit and fissure sealing? When is it suitable for pit and fissure sealing?

1, generally speaking, deep pit and fissure, especially those that can clamp the probe (including suspected dental caries);

2. The other teeth of the patient, especially the teeth with the same name or tendency to suffer from caries on the opposite side, should be sealed with pit and fissure;

3. It is suitable for pit and fissure sealing when children's teeth reach the occlusal plane after eruption, generally within 4 years after eruption.

4. The best sealing time is: deciduous molars are 3-4 years old, first permanent molars are 6-7 years old, second permanent molars are11-3 years old, and bicuspids are 9- 13 years old. For disabled children with poor oral hygiene, although they are older or their teeth erupt for a long time, we can consider relaxing the age of pit and fissure closure.

The method of pit and fissure sealing is very simple, which can be completed by tooth washing, acid etching, tooth washing and drying, sealing agent coating and curing. After curing, the material is closely attached to the ditch wall, which has certain chewing resistance and is harmless to eating. And after curing, the material is non-toxic and harmless to human body. However, it should be emphasized that pit and fissure sealing requires professional operation and necessary instruments and equipment. The sign of successful pit and fissure sealing is that the sealing agent can exist completely, and it is suspected that it is worn but cannot fall off, so it needs to be checked regularly, and the material falls off and needs to be re-sealed.

1, indicating; The pit and fissure is particularly deep, especially for the probe, other teeth, especially the opposite teeth with the same name, suffer from dental caries or have a tendency to dental caries.

2. Non-indications; There are no deep pits and cracks on the occlusal surface, and the self-cleaning effect is good. Those who suffer from more proximal caries have not suffered from caries for more than 4 years, and their teeth have not erupted normally and are covered by gums. The patient didn't cooperate and had his teeth filled.

Matters needing attention after pit and fissure sealing

1, high occlusion of closed teeth or pain during eating were found within a few days after operation, so please return to the clinic in time.

2. After operation, it is found that the sealing material falls off or partially falls off. Please come back for a follow-up visit.

3. Check every 6 months or 12 months after operation, so as to find problems and deal with them in time.

Question 2: What is pit and fissure sealing? Pit and fissure sealant is an effective method to prevent dental caries in children. When a child's teeth have pit and fissure caries, it can be coated on them, thus effectively protecting the teeth from further caries. Moreover, when the pit and fissure sealant falls, its material will penetrate into the teeth, which can also effectively protect the teeth. Pit and fissure sealant is a method to prevent pit and fissure caries by applying liquid resin on the surface of caries teeth and curing and hardening after entering the pit and fissure, which can effectively prevent teeth from further erosion. Many people don't know much about pit and fissure sealant. In this regard, the best age of pit and fissure sealing and the best age of pit and fissure sealing are introduced as follows. The principle of pit and fissure sealing is to synthesize a material that is harmless to many people and apply it to the cross-shaped pit and fissure of teeth. When it is liquid, it can penetrate into the pit and fissure on the surface of teeth and cure after illumination. Just like putting a protective coat on teeth, it can protect teeth from food erosion and effectively prevent dental caries. The best age for pit and fissure sealing is 6-8 years old, which is the best age for children to do pit and fissure sealing. The occlusal surfaces of newly erupted teeth and contralateral jaw teeth are not completely consistent. Pit and fissure sealing will not bring discomfort, and at this time, the child's permanent teeth have just erupted, and dental caries need to be sealed and protected in time. In the process of pit and fissure sealing, it is necessary to thoroughly clean the tooth surface and remove food residues and bacteria by using a soft toothbrush. Then the teeth are etched by acid, so that the surface of the pit and fissure presents tiny pores, which is beneficial to the infiltration of pit and fissure sealant to achieve the sealing effect. Finally, the teeth are completely dried to remove the residual water in the pit and fissure, without affecting the curing of resin and the bonding strength with the tooth surface. Apply pit and fissure sealant, and then cure with medical equipment to protect teeth. Through the above introduction, I believe that everyone has a certain understanding of when children should do pit and fissure sealing. Pit and fissure sealing is the best and most effective method to prevent dental caries at present. Pit and fissure sealing will not only have no effect on children, but also protect teeth. Moreover, pit and fissure sealing does not need to remove any tissue of teeth, which can effectively isolate the erosion of teeth by bacteria.

Question 3: What is pit and fissure sealing? This is a dental method to prevent tooth decay. There are many grooves on the front of teeth for chewing, but if these grooves are too deep, it is not convenient for daily cleaning, and it is easy to form tooth decay over time. The pit and fissure sealing is to fill these ditches to prevent tooth decay.

Question 4: What is pit and fissure sealing? What are the benefits? Pay attention to the observation and you will find that there are many tiny grooves on the occlusal surface of the posterior teeth, which are both pits and grooves. If the pit and fissure are deep, it is easy to suffer from dental caries, especially for children with poor oral hygiene. In order to reduce the occurrence of pit and fissure caries, doctors use dental materials (usually photosensitive materials) to seal the pit and fissure of teeth, which is called pit and fissure sealing. Pit and fissure sealing can reduce the incidence of dental caries when children have not developed good oral hygiene habits, but it cannot replace brushing teeth.

Question 5: Take the children to do pit and fissure sealing today. The key is free, but the doctor didn't tell me what to pay attention to. Is there anything to pay attention to? 1. The sealant in deep pit and fissure is generally completely cured within 7 hours, and fasting is prohibited within 2 hours after operation, and chewing food with closed teeth is prohibited within one day to avoid biting hard and rough food. 2. Within a few days after the operation, it is found that the occlusion of the closed teeth is high or it hurts when eating, so it is necessary to return to the clinic in time. 3. Due to saliva abrasion and other reasons, the pit and fissure are closed and fall off. Children who have done pit and fissure sealant should check in front of the mirror when brushing their teeth every day, or parents should pay attention to whether the pit and fissure sealant falls off. 4, pit and fissure sealant every 3 months or 6 months after the review, found that the problem in a timely manner. Within 2 years, the sealant can basically remain intact to prevent dental caries.

Question 6: What is pit and fissure sealant? The pit and fissure sealant is composed of polymer resin and curing agent, which has good fluidity. When coated on the tooth surface, the resin quickly penetrates into the pit and fissure, and the cured tooth surface forms a protective barrier to prevent bacteria and food residues from entering the pit and fissure, thus preventing dental caries on the tooth surface.

It has obvious characteristics: reducing caries rate, less cost, less pain and beautiful color. At present, pit and fissure sealing has been considered by the World Health Organization as a safe and effective caries prevention material, which can reduce the incidence of dental caries by more than 80%, and is non-toxic and harmless, even if it falls off, it will not cause harm to human body. Preventing children's dental caries is a method worth popularizing.

Good results have been achieved in the clinical application of Itemi in Shanghai, but now the occurrence of dental caries in primary school students is younger and more serious, so it is urgent to prevent dental caries.

Question 7: What is pit and fissure sealing? Tooth pit and fissure sealing is a kind of material (synthetic organic polymer resin which is harmless to human body and can self-coagulate) coated in the cross pit and fissure of teeth. When it is liquid, it can penetrate into the pit and fissure on the tooth surface and solidify after illumination. It is like putting a protective coat on your teeth to protect them from food erosion.

Question 8: What materials are commonly used for dental pit and fissure sealing? At present, the dental pit and fissure sealant used in clinic is light-cured resin. Different from ordinary resin filling, pit and fissure sealant has low strength and higher fluidity, which is beneficial for resin to enter tiny gaps and prevent bacteria from invading.

Children with deep teeth are prone to dental caries. It is recommended to change hospitals and close early.
