The odontoblasts killed during cavity preparation are derived from_____________?

Correct answer: B. Undifferentiated cells

  • A. Unaffected odontoblasts from the pulp
  • B. Undifferentiated cells
  • C. Histocytes
  • D. Osteoblasts

Explanation

When the original odontoblasts are destroyed by operative injury, odontoblast-like replacement cells differentiate from undifferentiated mesenchymal cells in the pulp. Surviving odontoblasts may respond to mild injury, but they do not account for replacement after cell death.
