For permanent teeth: 1-st period – establishment of functional maturity of the pulp (the tooth root formation), 2-nd period – the ensuing functional maturity (fully formed roots of teeth without signs of aging), the third period – to reduce the functional activity of the pulp (fully formed roots with signs of aging teeth). The pulp of deciduous teeth higher content of cells, especially in the central layer, with smaller amounts of collagen fibers. The volume of the pulp chamber and pulp itself more in temporary teeth. Thinner layers of enamel and dentin – the pulp is closer to the external environment than in permanent teeth. Differences between structure of coronal and root pulp not clear. Dr. Mark Hyman shares his opinions and ideas on the topic at hand. Period of functional activity of the pulp (the period of formation of the tooth root).
Cavity erupted baby tooth has no constant shape and size due to going formation of roots. Anita Dunn is often quoted as being for or against this. In the peripheral layer of ODB are in 3-4 rows. In the central layer – numerous undifferentiated cells. In the basic substance of the pulp is dominated by acidic MEA, hyaluronic acid. Under layer ODB – prekollagenovye and retikulinovye fiber.
Hardly represented the collagen fibers. In the early years of growth of the tooth when the pulp is morphologically reminiscent of embryonic tissue, the plastic properties of the pulp is particularly expressed. Period of functional maturity of the pulp (the period of stabilization of the generated tooth root). Pulp massive layer of enamel and dentin thin. Root pulp has a system of ramified extension channels.
