What are the factors that contribute to the onset of caries?

Caries is very harmful to the teeth, and we should actively ** caries. So what are the causes of caries? Let's take a closer look.

1. Heredity: Sometimes it is seen that parents have more tooth decay, and their children also suffer from caries. Some people believe that caries is also a genetic disease, which can be passed on to the next generation through genes in the body, that is, the constitution of parents who are prone to caries may be passed on to their children, so that they are also susceptible to caries, but the inheritance of caries is relatively less common than other inheritances.

2. Systemic factors: If the human body lacks certain nutrients for a long time, it often increases the chance of caries. For example, the long-term lack of vitamins A, B, C, and D in the human body not only makes the teeth lack calcium, but also affects the normal development of the jaw and prolongs the teething time.

Long-term deficiency of iron, calcium, and phosphorus in the body often increases the susceptibility to caries and makes them more susceptible to caries. People who have had certain medical conditions for a long time, such as tuberculosis, rickets, or children who have a frequent fever during tooth development, tend to develop tooth decay quickly.

3. Poor oral environment: the oral environment in which the teeth are located, including the amount of saliva, cleanliness, diet and so on. Problems in these areas are an important cause of caries.

4. Reduced or insufficient saliva is susceptible to caries: The saliva in the mouth is commonly known as "saliva", which contains a certain amount of bicarbonate, calcium, phosphorus, fluoride and antibacterial substances that have the effect of preventing caries. In recent years, anti-cariogenic antibodies have also been found in saliva, which provides a new basis for the study of saliva's anti-caries.

5. Neglect of oral hygiene is prone to caries: caries is closely related to whether oral hygiene is maintained regularly. The meaning of oral hygiene, in addition to not eating unclean food, is more important to quickly remove the residue in the mouth after eating food and drinking.

Otherwise, the bacteria in the mouth will multiply in large quantities with the residue of food or drink (i.e. the nutrients needed by the bacteria) and cause damage to the teeth. Therefore, people who usually eat snacks and do not remove their residues in time or do not brush their teeth thoroughly and neglect oral hygiene suffer from caries the most.

6. Defective tooth tissue structure and arrangement: In the prevention and treatment of caries, it is found that when the tooth development and calcification are poor, and the tissue structure is cracked and loose, its antibacterial and antiacid ability is low, and it is more prone to caries. Because this kind of tooth is easy to impede and retain food, it becomes a good foci of plaque and creates conditions for caries.

The incidence of caries is high, the distribution is very wide, and the harm caused to human beings is very great, especially the deep development of dental lesions, which can cause a series of complications such as endodontic disease, apical periapical disease, and jaw inflammation, which seriously affect the health of the whole body. So, in response to this problem, the following is a brief introduction to you one by one, and I hope that the following introduction can attract everyone's attention. Bacterial factorsMany studies have proven that caries does not occur without exposure to bacteria.

Common cariogenic microorganisms include Streptococcus spp. (e.g. Streptococcus haemois, Streptococcus mutans, etc.), Lactobacillus spp., and Actinomycetes spp. Food factors: The local effect of food in the oral cavity has an important impact on the occurrence of caries. Sticky or delicate carbohydrates (especially sucrose), such as pastries, biscuits, candies, etc., are easy to adhere to and retain, and are easy to ferment and produce acid, which can easily lead to the occurrence of caries.

After the oral environmental factors bacteria colonize the tooth surface, they also need to have a good environment suitable for their long-term survival and reproduction, so as to ensure that they have enough time and strength to destroy the teeth and form cavities. Time factor: The process of onset of caries takes a certain amount of time to complete. It can take months or even years for early caries damage to develop into cavities.

This is of great significance for the prevention of caries.

Answer]: The knowledge point of the e-god missing the test is caries**. Caries disease occurs under the combined action of four factors: bacteria-based scavenging, host conditions such as bacteria, carbohydrate foods, susceptible tooth surfaces, and a certain period of time.

The correct answer should be a quadruple factor, and any other individual items are not comprehensive.

Insufficient calcification, a large number of teeth, unclean mouth, and failure to develop the habit of protecting oral hygiene are all factors related to food that can corrode teeth and cause tooth decay. The best way to prevent it is to pay attention to the cleanliness and hygiene of your teeth, brush your teeth after meals, get up early before going to bed to brush your teeth, and use mouthwash to keep your teeth clean.

The causes of tooth decay are caused by the following.

First, bacteria.

Second, food.

Third, the host.

Fourth, time.

To prevent tooth decay, we can prevent it from the above four points.

The first and most important point is bacteria, without bacteria there can be no caries, this is confirmed, to reduce bacteria, it is necessary to brush your teeth, so be sure to brush your teeth morning and evening, at least three minutes each time, but also with dental floss to help clean up tartar, but also with mouthwash to clean the mouth.

Second, eat less sugar, especially sticky sugar, which is very easy to cause tooth decay, and drink less carbonated drinks, carbonated drinks can demineralize teeth, so it is easier to get caries.

Thirdly, if there is a crowded dentition, the patient can be corrected**, otherwise it will seriously hinder the maintenance of oral hygiene and be prone to tooth decay.

Fourth, time, that is to say, we must prevent the occurrence of caries in time, once the caries occurs, the teeth will be filled immediately, and the caries will not get deeper and deeper.

Oral hygiene is not cleaned in a timely manner, various nutrients needed by the body are not replenished on time, calcium or iron supplementation is lacking, and excessive food intake with high sugar content damages the enamel of the teeth themselves. In daily life, it is important to clean your teeth thoroughly, use the right toothpaste, clean your teeth twice a day, and also need to replenish calcium in time.

For example, eat sweets regularly. Eat sugar, or usually eat spicy things, so usually brush your teeth more, wash your hands frequently, and eat lighter food

What are the main caries bacteria that cause caries?

a.Streptococcus mutans.

b.Actinomyces.

c.Wei Yongji's Patan cocci.

d.Corynebacterium.

Correct Answer: a

Summary. With the development of oral preventive health care and various health care measures, people's living standards have been continuously improved, and the caries rate and caries have been controlled. The prevalence of caries in children is on the rise in developing countries due to factors such as the refinement of food structure, the increase in sugar consumption, the gap in people's awareness and behaviour of oral health, and the widespread development of preventive oral health care.

The report on the caries of baby teeth in China has risen sharply since the age of about 1, reaching a peak at the age of seven or eight, and then due to the replacement of milk and permanent teeth, the new permanent teeth have erupted one after another, and the caries rate of baby teeth has decreased, but in general, the caries rate of children is very high, so whether it is from the aspect of repair, or from the prevention of reducing this disease.

The prevalence of childhood caries in developing countries is on the rise in developing countries due to factors such as the refinement of food structure, the increase in sugar consumption, the gap in oral health awareness and behavior among people, and the widespread development of preventive oral health care work. The report on the caries of primary teeth in China has risen sharply since the age of about 1, reaching a peak at the age of seven or eight, and since then due to the replacement of milk and permanent teeth, the new permanent teeth have erupted one after another, and the caries rate of primary teeth has decreased, but in general, the caries rate of children is very high, so whether it is from the aspect of repair, or from the prevention of reducing this disease.

Today's young parents are busy with work and will ignore their children's dental problems.

Brushing your teeth in the morning and evening is not a daily routine.
