Functions Of Dental Pulp And Its Zones

Question 1. Zones of pulp.
Answer:

1. Odontoblastic zone:

• It occurs adjacent to the prevention
• It consists of odontoblasts lining the periphery of the pulp.

2. Cell-free zone of Weil:

• It is prominent in the coronal pulp.
• It is a space in which the odontoblast may move pulpward during tooth development and then to a certain extent in functioning teeth.
• It is inconspicuous during the early stages of rapid dentinogenesis.

3. Cell-rich zone:

• Adjacent to the cell-free zone Cell density is high in this zone
• It is composed of fibroblasts and undifferentiated mesenchymal cells.

4. Pulp core:

• It is characterized by the major vessels and nerves of the pulp.

Question 2. Functions of pulp.
Answer:

1. Inductive:

• Pulp induces the differentiation of dental lamina and results in enamel organ formation.

2. Formative:

• Pulp produces the dentin that surrounds it.

3. Nutritive:

• Pulp nourishes the avascular dentin.

4. Protective:

• It carries nerves that give dentin its sensitivity.

5. Reparative:

• Pulp is capable of producing new dentin when required.

6. Defensive:

• Pulp reacts to injury through the inflammatory process.
