Health departments and bureaus of all provinces, autonomous regions and municipalities directly under the Central Government, Health Bureau of Xinjiang Production and Construction Corps, Chinese Center for Disease Control and Prevention:

September 20, 2010 is the 22nd national " Love Teeth Day”. The theme of this year's event is "Sealing Pit and Fissures, Protecting Teeth" (see the attachment for details on the theme). It aims to popularize oral health care knowledge and promote the whole society to pay attention to children's oral health. In order to carry out this year's "Love Tooth Day" activities, the relevant matters are now notified as follows:

1. Effectively strengthen children's oral health work and create a good atmosphere for the whole society to pay attention to children's oral health. Children are in a special period of replacing deciduous teeth and erupting permanent teeth. They are a sensitive and high-risk population for oral diseases. This stage is also a critical period for acquiring oral health knowledge and establishing correct behaviors. Providing timely and scientific oral health care guidance to children and taking effective preventive and treatment measures will have a positive impact on their lifelong oral health and systemic health. Health administrative departments at all levels and all oral disease prevention and control institutions should attach great importance to children's oral health work as an important part of current oral health work, proactively report the status of local children's oral health work to local governments and development, reform, and finance departments, and actively Strive for support in terms of policies and funds to create a good atmosphere for children’s oral health work.

2. Focus on children, vigorously carry out health education and popularize oral health knowledge. Health administrative departments at all levels should work closely with education, publicity, radio and television and other departments to actively organize dental professionals to go deep into schools and communities, focusing on children, to carry out various forms of health promotion, popularize oral health knowledge, and guide the public to develop oral health care Good oral hygiene habits and doctor-seeking behavior. In order to facilitate the work of all provinces (autonomous regions and municipalities), our ministry will uniformly print the "Love Tooth Day" promotional materials and distribute them to all locations. All localities should post them in primary medical and health institutions, primary and secondary schools and other public places where people gather to ensure the efficiency and coverage of the use of promotional materials.

3. Strengthen training and improve the service capabilities and prevention and treatment levels of oral health professionals. All localities should make extensive use of the "Operation Specifications for Appropriate Techniques for Oral Prevention" issued by our ministry (Office of Health and Disease Control and Prevention [2009] No. 15) and supporting CDs to vigorously promote appropriate oral prevention technologies such as pit and fissure sealing among grassroots dental professional technicians. Ensure the provision of standardized oral preventive health care services to the public.

Fourth, vigorously carry out pit and fissure sealing among school-age children to ensure that children benefit. Centrally subsidized local public health funds. The pilot project areas for comprehensive intervention of children's oral diseases in the central and western regions should combine the development of the national "Love Teeth Day" activities and actively organize school-age children to voluntarily participate in oral health examinations and pit and fissure sealing, on time, with high quality, and We will ensure that we complete the work tasks to a certain extent and effectively implement the party and government's care for children. Other regions should also combine local actual conditions, seek support from various aspects, implement comprehensive intervention for children's oral diseases, and provide the best possible help to improve children's oral health.

Please submit the status of the National "Tooth Love Day" activities to the Bureau of Disease Control and Prevention of our Ministry before October 30, 2010.

Sealing pits and fissures to protect teeth.

2. Theme information

(1) Pit and fissure caries affect children’s dental health.

The uneven and concave parts of the occlusal surface of the back teeth are called pits and fissures, which are defects caused by fusion disorders of the cusps during tooth development. The pits and fissures of each tooth have different shapes and depths, which are suitable places for bacteria to grow and reproduce. In this calm and hidden environment, bacteria use the sugars (carbohydrates) in food to thrive and grow, and produce acidic substances during metabolism, corroding teeth and forming cavities. Therefore, deep pits and fissures are at risk of caries. Higher sex. At the same time, the bottom of the pits and fissures is close to the enamel-dentin junction or located within the dentin. Once caries occurs, the damage can rapidly develop deep into the cavity, forming a cavity that is small in appearance but actually deep and large. Medically, this type of caries is called pit and fissure caries. Caries can eventually spread to the dental pulp (dental nerve), leading to pulp inflammation or apical inflammation. If not treated in time, tooth loss will occur. The back teeth are responsible for the main chewing function. Once lost, the chewing function will be greatly reduced, affecting nutritional intake and growth and development.

Research shows that among children and adolescents in my country, pit and fissure caries account for 80-90% of dental caries. If the occurrence of pit and fissure caries can be effectively prevented and controlled, it can greatly reduce the incidence of pit and fissure caries in children. It can also reduce the personal economic burden and the consumption of social medical resources.

(2) Pit and fissure sealing is an effective method to prevent pit and fissure caries in children.

Fissure sealing refers to applying sealing materials to the pits and fissures on the occlusal surface and buccal and lingual surfaces of the crown without damaging the dental tissue to prevent cariogenic bacteria and acidic metabolites from damaging the tooth. Erosion, methods of preventing pit and fissure caries.

The principle is that the liquid resin solidifies and hardens after entering the pits and fissures, forming a protective barrier that covers the pits and fissures so that external cariogenic bacteria cannot enter again, thus achieving the purpose of preventing pit and fissure caries. This is just like in daily life, to prevent wood products from being corroded and moth-eaten, a layer of paint is applied to the surface, and to prevent iron products from rusting, anti-rust paint or plastic spraying is applied. This resin is non-toxic and harmless, does not affect people's chewing function, and can adapt to the oral environment.

Pit and fissure sealant is an effective method to prevent pit and fissure caries in children. As long as the pit and fissure sealant remains intact on the tooth surface, it can effectively protect our teeth. Even if the pit and fissure sealant falls off, the resin protrusions that penetrate into the tooth enamel will still protect the teeth to a certain extent.

Fissure sealing is mainly used on deciduous molars, permanent molars and permanent premolars. The best time for sealing is when the crown has fully erupted and caries have not yet occurred. Generally, the deciduous molars are between 3 and 5 years old, the first permanent molars are between 6 and 8 years old, and the second permanent molars are between 11 and 13 years old. Young people with deep pits and fissures can also perform pit and fissure sealing to prevent caries. With the wear and tear of chewing food, the pits and fissures of the back teeth of middle-aged and elderly people gradually become shallower or disappear. After the susceptibility period for pit and fissure caries, some people The patient already has cavities, so there is no need for pit and fissure sealing.

(3) Pit and fissure sealing is safe and easy to operate.

Fissure sealing is a painless, non-invasive, safe and simple caries prevention technique. The sealing material used is non-toxic and does no harm to the teeth. Even if the sealing material falls off and is swallowed, it will not have any adverse effects on human health. Children who receive confinement will not feel any discomfort during the confinement process. The whole process is divided into 6 steps and only takes about 10 minutes:

1. Cleaning. Remove food debris and plaque from the tooth surface.

2. Acid etching. Use weak acid to treat the tooth surface to re-clean and facilitate sealant adhesion.

3. Rinse and dry. Rinse the weak acid left on the tooth surface and dry the tooth surface until it becomes chalky.

4. Apply sealer. Apply sealant to the pits and fissures in turn.

5. Curing. By exposure to visible light, the sealer cures and hardens in about half a minute.

6． examine. Check the sealing effect.

Sealants can stay on teeth for several years. For newly sealed teeth, avoid biting hard or sticky foods, such as chewing gum and bubble gum. After sealing, it is best to re-examine every 3-6 months. During the annual routine oral examination, the sealed teeth should also be inspected. If any sealant is found to have fallen off, make up for it in time.

(4) The combined use of pit and fissure sealant and fluoride can prevent the occurrence of caries to the greatest extent.

Caries can occur in different parts of the teeth. Caries that occur in fissures and fissures are called pit and fissure caries, and caries that occur on the smooth surface are called smooth surface caries. Pit and fissure sealing can prevent the occurrence of pit and fissure caries, but it has no preventive effect on the smooth and adjacent surfaces of the teeth. Fluoride is a chemical anti-caries method that effectively prevents caries on the smooth and adjacent surfaces of teeth by enhancing the anti-caries ability of teeth and promoting remineralization. Therefore, the combined use of pit and fissure sealant and fluoride can prevent pit and fissure caries and smooth surface caries at the same time, maximizing the prevention of caries.
