Dentin Peripulpar

Dentin of peripulpal teeth and its dental manifestations.

Dentin is the tissue base of the tooth, consisting primarily of a mineralized collagen matrix. In the latter case, tooth dentin includes collagen fibers of type I collagen, as well as type II. One of the most important functions of dentin is to mechanically support the tooth.

Peripulpar dentin (juxtapulpar d.), as a subclassification of dentin, is characterized by larger organic fibers (compared to physiological dentin), however, the amount of calcified zone is still greater in the area of ​​the inner surface of the root. The structure of peripulpal dentin can be changed as a result of disruption of the hemostatic function of the pulp and contributes to the appearance of “dental nerves”. Peripulpal dentin is better suited for feeding plaque microorganisms, which leads to the creation of bacterial contents between the marginal zone and the forefoot of the pulpless tooth. This is the main reason for the development of caries and complications (for example, abscesses). The problem can be solved with appropriate dental restoration or at least constant oral hygiene
