S shape of dentinal tubules is due to______________?

Correct answer: C. Crowding of odontoblasts

A. Incremental deposition
B. Peritubular dentin
C. Crowding of odontoblasts
D. Due to excess amount of organic component

Explanation

The S-shaped course of dentinal tubules results mainly from the crowding and changing movement of odontoblasts as they retreat toward the pulp during dentin formation. Peritubular dentin is deposited around the tubules but does not create their overall S-shaped path.
