Template:Checked by Tooth decay is the most common infectious disease. The first theory about the causes of tooth decay was Miller's chemical-parasitic theory from 1898. It has not yet been disproved. 
Causes of tooth decay[edit | edit source]
- Bacteria – cariogenic organisms
- Low molecular carbohydrates (fermentable carbohydrates (sucrose, maltose, lactose) producing organic acids)
- Tooth plaque
- Poor oral hygiene
- Quality of hard dental tissues (partially conditioned by genetics)
Predilection sites of tooth decay[edit | edit source]
Among the places marked in this way are pits, grooves, contact surfaces, cervical third of the tooth, exposed roots, foramina ceca.
Distribution of dental caries[edit | edit source]
There are several different ways to divide tooth decay. 
- According to the involvement of hard dental tissues:
- according to the rate of progress:
- acute caries (caries acuta) - decaying matter is light yellow and the caries spreads quickly,
- chronic caries (caries chronica) – the caries progress slowly and the caries lesion is dark in color,
- arrested caries - darkly pigmented with completely hard base;
- according to the relationship to the vital dental pulp:
- superficial caries (caries superficialis),
- medium caries (caries media),
- caries close to the pulp (caries profunda pulpae proxima),
- caries penetrating the pulp (caries profunda ad pulpam penetrans);
- according to the nature of the course of caries in the dentin:
- undermining caries - little in the enamel, but mainly in the dentin just below the enamel,
- caries penetrating - leads quickly to the pulp;
- according to the place of occurrence on the tooth:
- primary caries – i.e. on an intact tooth,
- secondary caries - i.e. next to the existing filling,
- recurrent caries - i.e. under the existing filling (result of bad treatment).
