Which factor most determines (changes) root-canal anatomy over time?
Show answer and explanation
Correct answer: C. Age
Aging → ongoing dentin deposition → narrower, calcified canals.
- A. Caries affects the crown/pulp chamber but is not the general determinant of canal anatomy.
- B. Occlusal forces relate to attrition, not canal morphology change.
- C. Correct. With age, continued secondary/tertiary dentin deposition narrows and calcifies canals.
