Knowledge of popular science in stomatology

1. General knowledge of stomatology (what are the general knowledge of stomatology)

General knowledge of stomatology (what are oral knowledge) 1. What are the common oral knowledge?

The World Health Organization's statistical survey of 35 countries around the world shows that the incidence of periodontal disease is 40%-75%. According to some experts' estimates, more than 50% people in China suffer from periodontal disease, but the severity is the same as that people attach great importance to protecting their mouths, especially their teeth. Usually, their teeth are so painful that they interfere with their daily life that they are treated to death. In addition, their teeth are also damaged casually because of their high awareness of tooth protection. The situation of changing the normal growth of teeth is increasing year by year. Many phenomena have also attracted the attention of dentists. Some elderly people want to have their teeth pulled out immediately, or simply pull out the remaining good teeth. Dr. Li said that it is difficult for hospitals to do the work of the elderly. Old people often endure toothache and give up asking for denture replacement during treatment, which makes dentists very helpless to deny that compared with 10 years ago, most citizens' awareness of tooth protection has been enhanced. Dental problems are gradually emerging, lacking the concept of lifelong maintenance and disease prevention. At present, there are obvious problems in the process of tooth protection and tooth fixation in our country, while two-and-a-half-year-old children abroad have been doing regular system maintenance since they were four years old, and oral problems are an important link in preventing diseases, and important gums should be examined regularly. When problems begin to appear, brushing your teeth scientifically for two weeks will basically solve the development stage of the disease, which will be more troublesome to treat and even life-threatening in severe cases. The common misunderstandings of children's oral care need to be protected. This view has been widely recognized by young parents. Many parents think that deciduous teeth will be replaced sooner or later and ask their children to brush their teeth. In fact, deciduous teeth should be brushed from the beginning. Let children develop a good habit of brushing their teeth from an early age. When children begin to grow teeth, parents rub gums and tooth surfaces repeatedly with sterile gauze dipped in light salt water, and children will feel very comfortable when they grow small teeth. Parents should let their children watch their parents brush their teeth, and gently rub their teeth with a fingertip toothbrush or gauze dipped in warm water to help them brush their teeth. In order to gently brush your teeth with a children's toothbrush, children can learn to gargle when they are two years old, and gargle can wash away food residues. Gargling can replace brushing your teeth. Parents still insist on helping their children develop the good habit of brushing their teeth. At the stage, children need to use too much toothpaste, only the size of soybeans at a time. In addition, it is necessary to change biting lips, eating fingers and protecting deciduous teeth. Parents should take their children to the dentist for oral examination regularly from March to June, so as to find problems and treat them as soon as possible. For six-year-old teeth, it is often twice the result with half the effort to do pit and fissure sealing and early prevention and treatment in time. Myth 2: Tooth washing must be called tooth washing. Ultrasonic tooth cleaning machine is used to clean the tartar on teeth. Many people think that the efficacy of whitening teeth is actually confusing, because tooth washing washes away smoke stains and stains on teeth. People who have been treated in the past should consider washing their teeth, because their teeth are yellow and have no tartar. In addition, people who have washed their teeth report that they will be very sour after washing their teeth. There are two situations: when the teeth are sore, tartar often gathers at the gingival margin and the neck, and the neck is weak. When the teeth are close to the teeth nerve, they will feel sore. Some people feel hot and cold after washing their teeth. Sensitivity is due to blocking the external world from directly removing some sensitive factors through some channels in the tooth structure before removing tartar. Tooth nerve will have sensitive symptoms, which will gradually disappear in a few days or two weeks. Mouthwash often publicizes the efficacy of mouthwash in advertisements-it can reduce the number of oral bacteria and reduce the harm of bacteria. Combined with fluoride toothpaste, it can bring double protection to teeth and prevent tooth decay, thus attracting a small number of citizens to use mouthwash to remove oral odor. Some patients with oral inflammation will also choose to use mouthwash for anti-inflammatory advertising, and the effect has also been influenced by a few dentists. In fact, it is doubtful whether the professional mouthwashes used in hospitals on the market can also be commonly used. It is necessary to follow the doctor's advice. The mouthwashes sold in the market have certain bactericidal and anti-inflammatory effects. Healthy people have normal oral flora. Long-term use of mouthwash with antibacterial and anti-inflammatory effects in the market will cause imbalance of normal flora in the oral cavity. Therefore, it is suggested to use them for a long time to maintain the normal flora balance in the oral cavity, effectively clean the oral cavity and mechanically remove dental plaque. When there is gum abscess, severe periodontitis, oral ulcer and other acute inflammation in the mouth, it is recommended to gargle with drugs under the guidance of a doctor, which is not available in the market. The doctor will instruct the patient to use it according to the patient's condition.

2. like your teeth.

Brush your teeth in the morning and evening and after meals.

Change a toothbrush every three months. Brush your teeth with warm water of about 36℃, which is similar to the oral temperature. Brush your teeth with different toothpaste.

Key tooth food

Some ingredients in natural food can fight against oral bacteria that cause tooth decay and strengthen tooth enamel.

Tea: Fluorine contained in tea can be combined with apatite tuberculosis in teeth, which has the functions of acid resistance and tooth decay prevention. Among them, oolong tea and green tea have the highest fluorine content. Polyphenol contained in it is a complex composed of more than 30 substances, which has the efficacy of disinfection and sterilization, can reduce Streptococcus mutans causing tooth decay in the oral cavity, and has the effect of strengthening teeth. Drinking tea regularly can increase the flow of water and liquid in the mouth and maintain oral hygiene. Sugar, pectin and other ingredients in tea react with saliva to moisten the mouth and enhance the self-cleaning ability of the mouth. Chewing tea can also cure gum bleeding. However, it should be noted that when chewing, you should chew slowly and let the tea be ground and chewed into fine powder in your mouth before swallowing saliva.

Onion: Onion, especially fresh raw onion, can kill many kinds of bacteria, including Streptococcus mutans, which causes our tooth decay.

Lentinus edodes: Lentinus edodes contains lentinan, which can inhibit bacteria in oral cavity from producing dental plaque.

Mustard: Mustard contains some ingredients, which can inhibit the reproduction of Streptococcus mutans and lead to tooth decay.

Celery: Crude fiber food can sweep some food residues from teeth. In addition, hard chewing can secrete saliva, balance the pH in the mouth, and achieve natural antibacterial effect. Besides celery, sliced cucumbers and carrots can also function as gums.

Drinking water is the simplest but most important way to protect teeth. Drinking water in moderation can make our gums moist and drool. Drinking some water after a meal can take away the food residue in the residual mouth and prevent the bacteria that damage the teeth from getting nutrition.

Sugar-free chewing gum Chewing sugar-free chewing gum containing xylitol has obvious effect on inhibiting bacteria causing dental caries.

Key-tooth motion

Chewing: Chewing foods with appropriate hardness, elasticity and high cellulose content, such as coarse grains, miscellaneous grains, vegetables, fruits, etc., can exercise the chewing ability of oral muscles and teeth, and make the tooth tissue tough and firm and not easy to loosen. Chewing food fully when eating can * * gum, scrub tooth surface and bounce periodontal ligament, which can accelerate blood circulation, improve local nutrition and promote tooth health.

* * * Gums

Sticking teeth for 5 minutes every day can promote blood circulation and tissue metabolism, exercise muscles and protect skin, promote saliva secretion and clean mouth, and achieve the purpose of strengthening teeth and exercising periodontal function. If the teeth are slightly loose, you can use your index finger * * * gum 10 minute every morning. You can also roll the nucleus up and down in your mouth when talking about plums or apricots, which is of great benefit to prevent periodontitis and strengthen your teeth.

Key dental habits

Many people have the habit of brushing their teeth immediately after meals, thinking that this can minimize the chance of dental diseases. However, recent research shows that brushing your teeth immediately after meals is harmful to your teeth health. This is because there is a layer of enamel on the surface of the crown, which will soften after eating, especially after eating acidic food. Brushing your teeth at this time will cause enamel damage. Therefore, it is best to rinse your mouth with water after meals, and brush your teeth after 1-2 hours.

3. Oral health knowledge

How to choose toothpaste Choose toothpaste, first of all, we must know that toothpaste is not a magic weapon for dental health. It's just an auxiliary product for brushing teeth. It has the functions of rubbing, removing plaque, cleaning and polishing tooth surface and refreshing mouth.

At present, toothpaste used in China is divided into three categories: ordinary toothpaste, fluoride toothpaste and medicinal toothpaste. The main components of ordinary toothpaste are abrasives, detergents, wetting agents, preservatives and fragrances, which have the same function as ordinary toothpaste. If your teeth are healthy, you can choose ordinary toothpaste.

However, with the development of science and technology, it has been found that fluoride can prevent caries, and years of practice have proved that after fluoride comes into contact with teeth, hydroxyapatite which is easily dissolved by acid in tooth tissue forms insoluble fluorapatite, thus improving the corrosion resistance of teeth. Studies have proved that frequent use of this toothpaste can reduce the incidence of dental caries by about 40%.

Fluorides include sodium fluoride, potassium fluoride, stannous fluoride and sodium monofluorophosphate. However, we should know that fluoride is a toxic substance. If it is absorbed by the human body too much, it will cause fluorosis. According to the national regulations, the free fluorine in fluoride toothpaste should be between 400- 1200Pm. Children before the age of 3-4 should pay special attention, because 1/8- 1/4 toothpaste may be swallowed by them.

Medicinal toothpaste is based on ordinary toothpaste. When brushing teeth, toothpaste reaches the surface of teeth or the environment around teeth, and reduces dental plaque through the action of drugs, thus playing a role in preventing dental caries and periodontal disease. At present, medicinal toothpaste is very popular with people, and it is an ideal way to promote drugs with preventive or therapeutic effects by using toothpaste.

However, medicinal toothpaste also has its disadvantages. First of all, toothpaste can't stay in the mouth for too long, that is, it is washed away, which makes it difficult for drugs to exert their efficacy in a short time. Moreover, the dosage of special drugs must avoid the soft tissue in the mouth, so it cannot be increased to a sufficient effective concentration. The function of toothpaste itself is often blocked by oral dirt or restricted by morphological characteristics, so it is difficult to reach the real ward. Secondly, due to long-term storage, drugs in toothpaste often undergo other chemical changes and lose their original efficacy, while effective drugs are often not suitable for being put into toothpaste because of their peculiar smell. In addition, there is the problem of drug resistance. All these factors show that it is not suitable for long-term use of a medicinal toothpaste. It's a good idea to use medicated toothpaste, but some in-depth research is needed to really prevent oral diseases.

Therefore, in the face of a variety of toothpastes, we should first understand the performance of various toothpastes, don't blindly believe the product description, and it is best to consult a professional dentist to choose the appropriate toothpaste according to the actual situation of your mouth. Choose the right way to brush your teeth. The dentist reminds people to brush their teeth within 3 minutes after meals.

More than three times a day to prevent bacteria from depositing on the tooth surface and prevent dental caries. Brushing your teeth before going to bed at night is particularly important, because it can remove food residue and dirt accumulated on your teeth after three meals that day.

Otherwise, when sleeping at night, bacteria will breed in the mouth, and dirt and calcium salt deposition in saliva will form dental plaque and tartar, which is more likely to cause dental caries and periodontal disease. Each tooth has five faces.

That is, cheek, tongue, bite and two adjacent faces, it is not easy to brush all five faces. The correct way is to brush up and down. Tilt the toothbrush at 45 degrees, press it between the tooth surface and the gum, and try to let the bristles enter the gingival sulcus and between the teeth. Then brush vertically along the teeth and gently rotate the brush head, not too hard. Brush each tooth in turn for three minutes each time.

Brush the outside of the teeth: brush the teeth correctly at an appropriate angle, clean the outside of the upper and lower teeth, brush the upper teeth from top to bottom, and brush the lower teeth from bottom to top. Each position can be repeated 6~8 times. Brush the inside of the tooth: when brushing the inside of the tooth, brush it vertically along the tooth and rotate it gently. Don't just pay attention to brushing the outside of your teeth without paying attention to cleaning the inside of your teeth.

Brush the chewing surface of the teeth: brush the chewing surface of the upper and lower teeth in the front and back direction with appropriate strength. Finally, it is best to brush your cheeks and tongue as gently as possible.

The relationship between nutrition and teeth is often asked by dentists: "What to eat is good for teeth", which is a very complicated problem, and some problems are still unclear at present. As we all know, human health needs adequate nutrition to maintain.

Teeth are a part of the human body, so the health and development of teeth are also closely related to nutrition. When the fetus is still parasitic in the mother, all the nutrients he needs are obtained from the mother. Therefore, the health of newborns is closely related to the nutrition absorption of mothers.

After the baby is born, in addition to breastfeeding, it no longer depends on the mother's supply, and the required nutrition is directly obtained from the diet. During the growth and development of baby deciduous teeth and children's permanent teeth, if malnutrition occurs, it will directly leave undeveloped and unhealthy diseases on the teeth, which can affect the structure, shape and growth time of teeth and the resistance of teeth to caries.

For example, the hard tissue of deciduous teeth begins to calcify in the embryonic period, and the permanent teeth are calcified except the tip of the first permanent molar after birth. Calcium deficiency during pregnancy or birth will affect the calcification of hard tissue of teeth. The development and calcification of teeth have a direct impact on the occurrence of dental diseases.

In addition, the main nutrients related to dental health are vitamins and minerals. Meat, eggs, milk, vegetables, fruits and cod liver oil in food are all important sources of these nutrients.

For example, cod liver oil, because it contains a lot of indigestible elements A and D, can help calcium to be absorbed in the body, promote tooth development and calcification, and reduce the chance of dental diseases. Eating a certain amount of "fluoride" can increase the defense ability of teeth against dental caries.

If vitamin C is not given, it will affect the health of periodontal tissue. The local effect of food itself also has a certain impact on the health of teeth. Vegetables and other foods containing more vitamins have the function of cleaning teeth.

Children should be encouraged to eat a certain amount of coarse grains, because the contents of vitamins, calcium and phosphorus in coarse grains are higher than those in refined foods. It is also necessary to educate children not to have the habit of partial eclipse, because partial eclipse is easy to cause unbalanced food nutrition, which is not conducive to children's physical growth and dental health.

Enamel demineralization seriously affects the appearance of anterior teeth and increases the risk of caries. So, how to prevent enamel demineralization?

1. Maintain oral hygiene. It is usually recommended to brush your teeth three times a day for at least three minutes each time. For orthodontic patients, it is easy to leave food residue and it is difficult to brush teeth, so we should pay more attention to the frequency and quality of brushing teeth. It is best to rinse your mouth with clear water after meals to prevent dental plaque and food residue from accumulating on your teeth for a long time.

2. Reduce the intake of high-sugar diet and acidic drinks. Long-term intake of high-sugar diet such as bread, cake, chocolate, etc. ; Acid drinks such as cola, fruit vinegar and lemon juice will increase the chances of enamel demineralization, especially for children's deciduous teeth and young permanent teeth that have just erupted.

3. Use fluoride toothpaste. Demineralization is the dissolution and loss of calcium salt in tooth hard tissue. Fluoride can promote the re-deposition of calcium salt on the tooth surface, that is, promote the remineralization of teeth.

You should go to the dentist regularly.

Lack of water in the body will increase the viscosity of blood, and the blood will be too thick and thick, which will easily lead to thrombosis and induce cardiovascular and cerebrovascular diseases. Some elderly people will feel thirsty when they wake up after a night's sleep, which is also due to the fact that they can't replenish water in time at night and their blood is sticky.

It is reported that researchers from a university in Japan conducted a group study on male elderly people. One group got up in the middle of the night and drank 250 ml of boiled water, while the other group slept until dawn without drinking water at night, and then their blood concentrations were measured respectively. The results showed that the blood concentration of drinking water group was significantly reduced, and the risk of ischemic stroke and myocardial infarction was also reduced accordingly.

Because the thirst center of the elderly is not sensitive to water shortage, the elderly should always drink water when they are not thirsty. Besides drinking water actively during the day, you should also drink a cup of boiled water at night to dilute blood, reduce blood viscosity and reduce the occurrence of stroke and myocardial infarction.

Two patients came and said that they had a headache recently, and the pain was almost unbearable. After examination, it was found that their brains were full of leeches.

Later, it was found that their leeches came from a stream. I saw a clear and cold stream before going out to play, so I washed my face with my hands and found nothing unusual in the water.

But transparent leeches have entered their brains through their nostrils and multiplied. I thought it was a recurring migraine, and I didn't know it was a specific medicine for leech until I checked it.

At present, one has died, so everyone should pay more attention.

7. About oral knowledge.

How to protect teeth

To prevent dental diseases, we should start from an early age. When children are 2-3 years old, they can start brushing their teeth under the guidance of their parents or teachers to develop good hygiene habits. When the child is 6-7 years old, the deciduous teeth begin to fall off and the permanent teeth erupt one after another. At this point:

① Observe the normal alternation of deciduous teeth and permanent teeth. The first permanent molar will grow out around the age of six and remain unchanged for life. Many parents mistakenly think that it is a deciduous tooth and do not pay attention to it. Be sure to pay attention If you find dental caries, you should treat them as soon as possible.

2 Pay attention to whether the occlusal relationship and arrangement of teeth are normal, because this will affect the chewing function and beauty of children. Maldentition should be corrected before 14~ 15 years old. If you exceed this age, it will be difficult to achieve the expected curative effect.

Effective prevention methods

1. Pay attention to oral hygiene and develop the good habit of brushing your teeth in the morning and evening and gargling after meals.

2. Master the correct brushing method, that is, rotate your teeth up and down, brush your teeth from top to bottom, and brush your teeth from bottom to top, gently and without force; Brush all your teeth. Brush for 3 minutes at a time.

3. Choose a healthy toothbrush with soft head. After using the toothbrush, put the brush head up, dry it and use it next time. Because the toothbrush is easy to breed bacteria, the toothbrush should be replaced with a new one after 1~3 months.

Don't eat sweets and biscuits before going to bed, and don't forget to brush your teeth.

5. Educate children not to be partial to food, not to chew unilaterally, not to bite fingers and pencils, and to eat more coarse fiber foods such as vegetables. Strengthening chewing function is beneficial to the normal development of maxillary system and reducing dental diseases.

6. Choose appropriate oral health care products and adhere to oral cleaning care.

7. Go to the Department of Stomatology for oral examination regularly, preferably once a year from March to June.

Brush your teeth in the morning and evening and regularly (usually once every six months)!
