Our goal is no tooth decay. What does this sentence mean?

Is to protect our teeth from tooth decay. Generally, it is the advertising language of toothpaste.

The survey shows that there is a positive correlation between children's intake of sweets and dental caries, and the risk of dental caries will be reduced for children who start brushing their teeth before the age of 3, which is consistent with the epidemiological survey of dental caries in children's deciduous teeth and the analysis of related factors conducted by Zhang Jian and others.

The reason is that the enamel and dentin of preschool children are thin, the degree of calcification is poor, and the anti-caries ability is low. Most children do not have the hygienic habit of brushing their teeth in the morning and evening and gargling after meals, which creates conditions for bacterial invasion and reproduction and eventually leads to dental caries. At the same time, the occurrence of dental caries in children depends largely on the importance parents attach to oral health.

The survey results show that parents understand oral health knowledge and the harm of deciduous teeth caries, pay attention to children's oral health and eating habits, and take their children for oral health examination regularly, so the caries rate of children's deciduous teeth is low.

Extended data:

Clinically, we can see the changes in the color, shape and quality of dental caries, mainly qualitative change, which is the result of qualitative change. With the development of the disease course, the lesion enters dentin from enamel, and the tissue is constantly destroyed and disintegrated, gradually forming a tooth cavity. Clinically, according to the degree of dental caries, it is usually divided into the following three stages:

1, shallow caries

Also known as enamel caries, caries is limited to enamel. In the early days, the smooth surface showed chalky spots caused by demineralization, and then turned yellow-brown due to coloring. The pit and fissure show that the ink is soaked and dispersed. Generally speaking, there is no obvious dental caries, but there is a rough feeling during exploration. In the later stage, shallow holes confined to enamel appeared, with no conscious symptoms and no response during exploration.

2. Moderate dental caries

Dental caries have reached the surface dentin. There are obvious cavities in clinical examination, and there may be pain detection. There may be painful reaction to external stimuli (such as cold, hot, sweet, acid and food embedding). When the stimulus is removed, the pain disappears immediately and there is no spontaneous pain.

3. Deep caries

Caries have reached the deep dentin, which is generally characterized by large and deep cavities, or small and deep cavities with extensive damage. The response to external stimuli is heavier than moderate caries, but the pain can be relieved immediately after the stimulus source is removed, and there is no spontaneous pain.

4. Dental caries

X-ray film shows black transmission area. For those who are difficult to diagnose (such as adjacent caries), X-ray film can be used to assist diagnosis.
