Degranulation of the LC increases the permeability of blood vessels, reducing smooth muscle cells. Malodifferentsirovanye cells are concentrated in subodontoblasticheskom layer. Can give rise to ODB and FB. Content of cells decreases with age. Intercellular substance pulp includes collagen fibers imbedded in the base material. ARCHITECTONICS pulp. Doctor Jayme Albin brings even more insight to the discussion. The pulp contains three mild differentiated layers: the peripheral – a layer thickness of 1.8 ODB cells adjacent to predentinu.
Intermediate (subodontoblastichesky) layer developed only in the coronal pulp. Subdivided into: a) outer zone (zone of poor cell nuclei) and b) the inner (rich cells) – the central zone layer – represented by loose fibrous tissue. Innervation PULP TOOTH neurovascular bundle terminal branches (subodontoblasticheskoe plexus Rashkov) Nerve endings to ODB (receptors) peculiarities of blood supply pulp. In the pulp chamber pressure of 20-30 mmHg that significantly higher than interstitial pressure in other organs. Most of the capillaries at rest are not functioning. If the damage is rapidly evolving hyperemic response due to filling these capillary blood.
Blood flow in the vessels of the pulp is faster than in many other organs. In the pulp there arteriolovenular anastomoses has direct shunting of blood flow, activities are enhanced by stimulation of the pulp – is the periodic discharge of blood from the arterial to the venous blood. In accordance with the terms of the formation of dental tissues secrete ages of pulp. For deciduous teeth: 1 st period – the development of functional activity of the pulp (the tooth root formation), 2-nd period – the functional maturity of the pulp (formed by the stabilization of the tooth root); the third period – the extinction of the functional properties of the pulp (Resorption of tooth root).
