Dentin Plashevoy

Mantle dentin is the layer of dentin located directly beneath the enamel of the tooth. It surrounds the innermost layer of dentin, the peripulpal dentin, which is found around the pulp of the tooth.

A distinctive feature of mantle dentin is the radial arrangement of collagen fibers. Unlike other types of dentin, the fibers in mantle dentin are oriented perpendicular to the surface of the enamel and run radially from the pulp to the enamel. This structure ensures maximum strength of mantle dentin and allows it to withstand chewing pressure.

Mantle dentin performs an important protective function - it covers the tooth pulp and protects it from harmful external influences. Due to its special structure, this dentin layer has high strength and elasticity, which makes it an important component of the hard tissues of the tooth.
