Question

Arrange the following zones of the pulp from outer to inner layer in the correct sequence:

• A. Odontoblastic zone
• B. Cell rich zone
• C. Cell free zone
• D. Central pulp

Hint:

Understanding the structure of the pulp and its layers is essential for dental professionals in diagnosing and treating pulp-related conditions.

Answer 1

The Correct Option is A

The correct sequence of zones of the pulp from outer to inner layer is: 
1. Cell free zone: This is the outermost layer of the pulp, also known as the zone of Weil. It contains fewer cells and more collagen fibers. 
2. Odontoblastic zone: This layer is located just beneath the cell-free zone and contains odontoblasts, which are responsible for the formation of dentin. 
3. Cell-rich zone: This is the middle layer of the pulp and contains various types of cells, such as fibroblasts, macrophages, and immune cells. 
4. Central pulp: This is the innermost layer of the pulp and contains blood vessels and nerves that supply the tooth. 

Therefore, the correct sequence is 1324.
