The teeth is an anatomical structure located in the oral cavity of multiple vertebrates whose main function is chewing. Teeth are needed by a number of functions such as the following;
On the other hand, the teeth are very important socially, as they are one of the main things to make a good impression of the person. In this post, we will see what the teeth are formed of. The teeth are formed by 3 structures mainly;
The dental enamel is a mineral layer of great purity, which externally coats the crown of the tooth. The enamel is very hard and its function is to protect the tooth against harmful influences from the outside, especially from the wear and tear. It consists of 95% of minerals, mainly phosphate and calcium, and one hundred percent of the organic substances i.e. proteins and four percent water. In this layer, it is where the fluoride acts to prevent the cavities. Fluoride forms larger crystals, thereby, reducing the volume of the pores, improving the re-mineralization process.
Below the enamel are the dentin. This layer not only surrounds the crown, but also the root zone, specifically the dental pulp.
The dentinal tubules, which partially contain neuron extensions, have a variable density; the tubular density is higher in the vicinity of the pulp. The lateral tubules of the dentine of the mantle contain a greater amount of a transparent liquid. Unlike the enamel, formed by high purity mineral in the dentin can be carried out the processes of adaptation in mode of tertiary dentine, calcifications of ducts and displacement of liquid to a limited extent. This property is linked to the high proportion of organic components of the dentine, formed in 20% of its weight by organic substances, 70% by minerals and 10% by water. This composition also makes the dentin softer than the enamel.
When the dentin feels attacked by an infection such as caries, it creates tertiary dentin with the objective of removing the lesion from the pulp chamber. When diagnosing the dental caries, it is important to detect it in the early stages.
The last layer that we find, and that is of vital importance, is the dental pulp. The dental pulp is a connective tissue rich in vessels and nerves. Healthy teeth, which contain an intact pulp, are called vital teeth, which means they react to external stimuli such as cold. When an injury expands to the complex of the pulp, it can become necrotic, losing vitality and therefore a root canal or endodontic treatment has to be performed.
