From time to time, when faced with toothache, we do not always think about how toothpaste is arranged and what kind of tooth tissue is. Let's consider this question in more detail.
Tooth have their structure and composition. In order to understand well the problems and diseases of the teeth, it is important to know what they are and how they work.
The tissues of the tooth: the structure
The structure of the tooth is determined mainly by solid tissues, but inside there is also a soft connective tissue that is infiltrated with a large number of nerve endings and vessels. The structure of the tooth fabric is as follows.
- Enamel - a very strong and hard fabric, which tooth is covered externally. In addition to its strength, the tooth enamel is quite fragile. The composition of the enamel includes high concentration minerals. The thickness of the enamel layer ranges from 0.01 mm to 1.5 mm, depending on the location and functional characteristics of the tooth. On the outside, the enamel layer is covered with a protective sheath.
- Considering the tissue of the tooth in the cut, you can see that the next layer of the deep structure of the tooth is dentin. It is considered to be the main component of the tooth and its structure and properties are close to bone tissue. There are two layers of dentin: the outer (which forms the crown) and near-pulp (covered with dental cement). These two layers have a connection in the area of the neck of the tooth. This connection can be of several types: lace, overlap, and when between the enamel and the cement remains uncovered part of the dentin.
- The pulp (fluffy fibrous component of the tooth) consists of connective tissues, blood vessels, nerves, rich in cellular elements. According to the cell composition, this fabric of the tooth is divided into three layers: central, intermediate, peripheral. The central layer is saturated with fibroblasts, peripheral - odontoblastami. The interlayer is rich in histiocytes (vagus cells). Such tissues of a tooth, like a pulp, are divided into crown and root portions. Functions of the pulp: protective, nutritious, plastic and barrier.
- Cement refers to the hard tissues of the tooth and its structure is similar to the human bone. The structure is the primary (non-cellular) and secondary (cellular). The composition of the original includes collagen fibers, they are placed in several directions. Secondary cement contains in its composition a cement region and has a layered structure.
A good knowledge and understanding of the structure of the tissue, you can avoid the development of various diseases of the tooth.
The tissues of the teeth are prone to illness
In addition to the well-known tooth decay, tooth tissues are prone to many other diseases that in one way or another violate the structure of the tooth and lead to deterioration of the quality of life. Having considered in more detail the structure of hard and soft dental tissues and having an idea of the possibilities of development of diseases, it is possible to stop the disease of the tooth at the initial stage.
To prevent dental health, a person of any age should regularly visit a dentist and follow his recommendations for oral care.
