1. What are the hazards of dental caries?
1, affecting the growth and development of patients.
Because dental caries are often painful, deciduous teeth fall off early, chewing function is reduced, and digestion and absorption of gastrointestinal tract are weakened, which leads to malnutrition and affects growth and development.
2, cause infectious diseases
When children's dental caries cause periapical infection, it often becomes the focus of infection, causing lovely systemic infection. Related diseases include vision loss, arthritis, nephritis, myocarditis, long-term low fever and so on.
3, cause root granuloma, cyst,
Dental pulp infection, etc
Dental caries can be the focus of infection, which can induce nephritis, rheumatic fever, tonsillitis, impetigo, scarlet fever, sepsis and so on. When the body's resistance drops, such as fatigue and cold. Studies have shown that there are deep caries
8 1% of children with tooth, residual root and tooth abscess have local lymphadenopathy, especially submandibular lymph nodes. After caries treatment, 70% of the swollen lymph nodes can subside.
4, leading to an increase in oral temperature.
The oral temperature of children with dental caries is higher than that of normal children, and the total number of white blood cells in blood increases, the erythrocyte sedimentation rate increases, the red blood cells decrease, the hemoglobin is low, and the total serum protein changes. After caries treatment, it returned to normal, but the total serum protein did not change much in a short time. Therefore, when children have unexplained low fever, anemia, elevated white blood cells and accelerated erythrocyte sedimentation rate, oral examination should be performed first.
5, causing psychological barriers
Infants and young children are learning language, and complete deciduous teeth help children master correct pronunciation. Dental caries and premature loss of deciduous teeth can make children's pronunciation unclear. The serious caries in the anterior teeth of deciduous teeth make some children shy to speak, which is very unfavorable to their psychological development.
2. How to treat dental caries correctly?
The harm of dental caries is so great that we must adopt correct treatment methods:
Grinding method of rotten tissue
It is suitable for teeth with a wide area of caries, such as full occlusal surface caries, enamel or dentin peeling, and can not be made into filling teeth. Focus on grinding off the sharp cusp, tooth edge and surface caries tissue to prevent the caries from developing.
drug therapy
It is suitable for initial caries with shallow caries ring and no cavities. The drug used is ammonia silver nitrate. Rub the diseased tissue with ammonia silver nitrate cotton ball, generally rubbing repeatedly for 1-2 minutes, and blowing with hot air.
After drying, repeat 1 time, and then blow dry to achieve the purpose of drug treatment of decayed tissues. Because ammonia silver nitrate is an antiseptic and bactericidal drug, it has the functions of antisepsis, convergence, sterilization and antisepsis.
Generally, the decayed tissues smeared with ammonia silver nitrate cotton balls are smeared with clove oil or 10% formalin cotton balls to produce silvery black, which can form protein silver and reduced silver, which are deposited in dentinal tubules and block dentinal tubules, leading to.
Bacteria in dentinal tubules stop reproducing, and finally prevent the development of dental caries. Drug therapy is often combined with grinding tissue, and the effect is better. Drug treatment is only suitable for posterior teeth treatment, because ammonia silver nitrate can make teeth
Dyeing, so it is not suitable for anterior teeth treatment.
Remineralization method of dental caries tissue
It means that the mineralized solution of calcium, phosphorus and fluorine is artificially prepared to act on the teeth, so that the tissues in the tooth lesion area are mineralized, that is, the calcium, phosphorus and fluorine in the mineralized solution penetrate into the tooth lesion area. This will make the diseased tissue heavier.
The process of obtaining new minerals is called remineralization. The remineralization method of decayed tissue is suitable for early dental caries. The specific method is to gargle with artificially prepared mineralized solution. Clinical use of remineralization to treat deciduous tooth caries can make it chalky.
Shrinkage, or stop developing. The remineralization therapy is simple, effective, painless and safe.
How to prevent dental caries in diet
First of all, it is necessary to carry out nutrition prevention and control. In the fetal period, we should pay attention to the nutrition of pregnant women and supplement enough vitamins and minerals such as calcium and phosphorus. These ingredients are necessary for the fetal development stage, and can also lay a good foundation for him to grow healthy teeth in the future.
Secondly, eat less sugar. Sucrose is closely related to dental caries and plays a decisive role in the occurrence of dental caries. From the beginning of children, we should pay attention to controlling the amount of sugar, not allowed to eat candy snacks before going to bed, and even develop the bad habit of sleeping with candy in your mouth.
Third, pay attention to a balanced diet. Infants with various malnutrition and chronic wasting diseases should pay more attention to supplement sufficient calcium and phosphorus, B vitamins and vitamins A and D.
Vitamin c, vitamin d, etc. , especially fresh melons and fruits, should eat more to improve the ability to resist dental caries. Because high-protein diet can prevent dental caries and fat can protect teeth, it can reduce the occurrence of dental caries.
3. Precautions for dental caries diet
1, eat less hard and rough food.
Eating hard and rough food for a long time is easy to wear teeth and gums, and it will shake the teeth nerves when chewing, which is easy to "wake up" the nerves in dental caries and cause toothache. Eat less roasted seeds and nuts such as fried peanuts and broad beans and fried foods such as fried chicken and French fries.
Step 2 eat less sweets
Sucrose has obvious cariogenic effect. Eating sweets often will cause sugar to remain in your mouth. If it is not cleaned in time, it will produce acidic substances, corrode teeth and damage local tissues. And sweet and greasy food will also affect children's digestion and absorption.
3. Eat less acidic food.
The formation of dental caries is related to acidic food, which accumulates in teeth, produces excessive lactic acid, corrodes the surface of teeth and forms tooth decay. Therefore, people with dental caries should eat less pomegranate, waxberry, jujube and other foods, rinse their mouths after eating acidic food, and clean up the food residue between their teeth.
4. Eat less cold and overheated food.
Dental caries patients are more sensitive to the stimulation of hot and cold food because their teeth are damaged and their pulp nerve endings are exposed. Eating food that is too cold or too hot can easily stimulate nerve endings and cause pain.
Step 5 stop drinking
Wine contains alcohol, which will stimulate the pulp nerve and cause pain after drinking. If children have dental caries, they should never drink alcoholic drinks. In addition, carbonated drinks and coffee are not suitable for drinking.
6. Control the intake of fluorine-containing food.
Fluorine is one of the most important elements to maintain tooth health, which is beneficial to the calcification and metabolism of tooth tissue, helps teeth to enhance acid resistance and caries resistance, and effectively prevents tooth decay. When the daily intake of fluorine is less than 0.5ppm, the incidence of dental caries will reach 70%-90%. However, if the fluoride intake exceeds 1ppm, the teeth will gradually produce spots and become brittle. Therefore, the daily diet should control the intake of fluorine-containing food, not too much, not too little.
