sequence:

  1. Odontoblastic zone
  2. Cell rich zone
  3. Cell free zone
  4. Central pulp
  1. 1324
  2. 1234
  3. 3241
  4. 3214
    Ans. 1 (1324)
    Solution. 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
