Child's deciduous teeth caries

Dental caries will occur in many children. Because children are in the teething stage, it is easy to get dental caries during the teething period. First of all, it will affect the normal system of the teeth and cause some deformities. It will also affect the normal eating of children. Rough food cannot be digested in the stomach and will affect the small intestine, which will also affect the absorption of nutrients. This requires special attention.

Since children are in the stage of growth and development, the harm caused by dental caries can affect the development of the dental system and cause acquired deformities. The pain of tooth decay can affect children's eating, causing them to be afraid to chew with diseased teeth. Food goes into the stomach without being chewed carefully, which increases the burden on the stomach and causes stomach pain.

Rough food cannot be completely digested in the stomach, which will affect the absorption of nutrients by the small intestine. Over time, the child's physical fitness will be reduced. If dental caries are not treated promptly, they will further develop and cause inflammation of the dental pulp and around the root apex, causing unbearable pain. In addition, because of the pain, long-term eating on one side can affect the growth and development of the maxillofacial area, and even cause deformities such as one side of the face being larger than the other. Therefore, dental caries in children must be treated promptly.

Causes

The etiology of childhood dental caries is a four-factor theory, which mainly includes bacteria, oral environment, host and time. Its basic point is: cariogenic foods (especially sucrose and refined carbohydrates) are tightly attached to the acquired film formed by salivary proteins on the tooth surface in the sugar. In this film formed by the anatomical structure, biochemical and biophysical characteristics of the tooth surface, it can not only be firmly attached to the tooth surface, but also have enough time and at a suitable temperature to produce acid in the deep layer of the plaque, eroding the teeth, demineralizing them, and then destroying the organic matter and producing caries.

1. Bacteria

It is a necessary condition for the occurrence of dental caries. It is generally believed that there are two types of dental caries bacteria. One is the acid-producing bacteria, mainly Streptococcus mutans, Actinomyces and Lactobacillus, which can decompose carbohydrates to produce acid, leading to demineralization of tooth inorganic matter; the other is Gram-positive cocci, which can destroy organic matter and cause tooth cavities after long-term action. The recognized main cariogenic bacteria is Streptococcus mutans, and others include Actinomycetes, Lactobacillus, etc.

Bacteria mainly adhere to the tooth surface with the help of plaque. After the carbohydrates in the food retained in the mouth are degraded, on the one hand they polymerize to produce highly viscous glucans to form the plaque matrix, and on the other hand they produce acid to demineralize the teeth. The composition of the plaque is relatively complex. In addition to a large number of bacteria, there are also sugars, proteins, enzymes and other substances.

2. Oral environment

The oral cavity is the external environment of teeth and is closely related to the occurrence of caries, among which food and saliva play the dominant role.

Food is mainly carbohydrates, which are related to the formation of plaque matrix and are also the main energy source for bacteria in plaque. Bacteria can use carbohydrates (especially sucrose) to metabolize to produce acid and synthesize extracellular polysaccharides and intracellular polysaccharides. The organic acids produced are beneficial to the growth of acid-producing and acid-resistant bacteria, and are also beneficial to the demineralization of dental hard tissues. Polysaccharides can promote the adhesion and accumulation of bacteria on the tooth surface and provide an energy source when exogenous sugar is lacking. Therefore, carbohydrates are the material basis for the occurrence of dental caries.
