Dentin fibers

Dentin fibers are microscopic protein threads that form the basis of dentin, the hard structure of the tooth. They are formed as a result of the tooth formation process - the mineralization of dentinoblasts - young cells of the dental bone marrow. In total, two layers of dentin are formed from odontobasts: the outer or fibrous and the inner, called the placenta. The outer layer is named because it looks like fringe, or rather very thin fibrous threads about a centimeter long. Its growth reaches several millimeters per minute. Throughout life, excluding infancy, the thickness of the fibrous layer reaches a thickness of about three centimeters.

The fibrous structure of dentin is given by the protein amelogenin and calcium carbonate, which is contained in food and nourishes dental tissues.

The mass of the dentinal process, which later received the name dentin, increases due to the formation of new fibers around the callus of the tooth root. This is how these microfibers are built from tooth cells. Because of their number, strength and shape, they are also called protein threads. One tooth hair is enough to catch them on the tooth cheek. But this is not their only function. Connected by special acid bonds, the protein processes form the so-called matrix, the hard internal basis of the tooth, the “dental bone,” as we say. They give strength to the tooth itself and are united by a connective tissue network, thus creating a kind of solid frame. The dentary bone itself (including the matrix) is an organic material, although its chemical composition is close to the bones of the skeleton,
