“Tooth”

The Word “enamel" means yet? Thus, in anatomy and dentistry of tooth enamel are considered very durable thin layer of inorganic substances (approximately 97%) and organic (about 3%), which protects the crown of the tooth. This material is the driest part of the human body and also the most durable concurrently.

The Exceptional hardness of tooth enamel due to the hydrated form of Apatite, which is "reinforced” with inclusions of magnesium, chlorine, fluorine, barium, chromium, a small number of organic substances. Organic components are collagen, which significantly increases the practical strength of the enamel by reducing the brittleness of the latter.

Strong enamel strong teeth

For the modern human enamel care – an important component of hygiene and prevention of diseases of the oral cavity. Mainly Apatity structure to protect the crown of the mechanical, but is itself poorly protected from harsh environments, and extremely sensitive to the acidity of the environment.

Even when the value of pH = 4,6 enamel of the tooth is subjected to significant destruction. The normal acidity of the saliva does not reach such values, however, the bacteria in the oral cavity quickly "acidification" environment. A by-product of their activity are organic acids, which pose the greatest threat to enamel.

The Problem is solved by removing food debris after a meal that deprives the microflora of the actual supply. Another danger to the enamel lies in the products that initially have a pronounced acidity. So, the damage can cause the substances contained in some fruits (organic acids) or soft drinks (phosphoric acid).

What is the enamel? Figurative sense

It is Easy to see that the common meaning of any of the definitions of the enamel is a thin protective layer. That is why in the everyday life of man any such thing as “enamelware” and “amalina paint». To this enamel, they are not related, but a verbal “enamel" carries them in a protectionist sense.

Enamel ware called in domestic kitchenware, in which the metal (often steel) is covered with a thin glass-like ceramics. Layer performs a protective function and also allows to avoid contact of food and metal.

Amalie paint is a coating protectors for metal components in the industry, manufactured on the basis of varnish. They contain a part of the solvent, the actual varnish, pigments, fillers and spardabank. As is clear, a common response to the question of what “enamel" is not quite competent in relation to enamel-paints either in terms of ingredients, either in terms of method of application on surface.
