Age changes in dentin-pulp complex

 Following changes appear in the dentin-pulp complex with time.

1. Decrease volume of the pulp chamber and root canal due to continuous deposition of dentin.
2. Decreased vascular supply to pulp.
3. Reduction in the number of cells. The number of cells becomes half between ages 20 to 70.
4. Loss of myelinated and unmyelinated axons leads to a reduction in the sensitivity of dentin.
5. Increase in dead tracks and sclerotic dentin.
6. The appearance of areas of dystrophic calcification.
7. Increased sclerotic dentin deposition leads to increased brittleness and decreased permeability.
