According to the World Health Organization (WHO), dental caries is one of the most common chronic disease in humans. It can reach all the teeth as the permanent bolesti.Karijes disease generates interaction of four factors, and evolving in four stages.
factors for the development of dental caries: a scheme Keyes
development of carious lesions is due to the coexistence of four factors:. Plaka, land, food and time
Bacterial plaque
in the oral cavity of human beings, more than 60 different kinds of bacteria alive, who participates in the formation of bacterial plaque (see scale and scaling). Some of these bacteria such as streptococcus and / or Lactobacillus produce acids that can attack the mineralized tissues of the teeth and cause tooth decay as dobro.Rizik of caries will be even greater than the number of bacteria present in the mouth is important.
Field
Some people are more likely to have cavities, they are said to be more fertile ground for the development of carious lesions. This happens when the enamel is thin and less resistant to acid attack plaque bacteria. Likewise, dental fillings (amalgams and / or composites, crowns), and the old mat to keep the food more easily make brushing less effective and to promote the formation of bacterial plaque.
Food
Some foods are rich in acidic (fruit juice, sodas) and contribute to weaken the tooth enamel by dematerializing. Other rich in sugars (candy, chips, and crackers) are used by bacteria to assimilate, grow (up panel), and then convert them into acid waste is responsible for the demineralization of tooth enamel.
After the tooth gets decayed there is a need for tooth replacement, if you want to smile in public and take the taste of food again.
during
development of caries requires time and involves several steps. Four developmental stages of decomposition:
1 The destruction of the enamel
acid bacteria from food, or start with a dematerialized enamel. This process is completely painless and can be viewed by a dentist during a dental examination (clinical and radiological). At that time decay is still reversible, because the ions present in saliva (see scale and scaling) can mineralize the enamel surface. This is the regular repetition of stress (food, plates), which will enable the process of demineralization and thus continue the growth of tissue beneath the enamel of the teeth.
2 Reached the dentin
This is when a tooth becomes sensitive to hot, cold, sweet and sour: one speaks of the pain caused. Dentin is less mineralized than enamel, which is faster demineralization, and thus decay will spread and grow faster in the tooth pulp.
3 Invasion of the pulp
This is the stage of "toothache" pain is violent, spontaneous and / or caused by heat, cold. If treatment is not carried out the pulp will die gradually become necrotic.Bol stops after a while can give the impression that all is well.
4 Invasion of surrounding tissue
Bacteria are present throughout the pulp and will move to the top of the root and get through the apical foramen (see the anatomy of the tooth) and surrounding tissues (gums, bone and ligaments). Be formed in the longer term abscess and / or cyst is very painful at the end of the root. This infection can spread, or adjacent tissues and to give a "classy" (buffer) or the whole body through the blood vessels and is responsible for the infection of other body parts (eyes, lungs, heart, kidney and joints).
