Fully calcified dentin associated with aging or slowly advancing caries is called?

• A. Sclerotic dentin
• B. Dentin sclerosis
• C. Primary dentin
• D. Secondary dentin

Answer: (A)

Sclerotic dentin occurs when dentinal tubules become filled with mineral deposits, a response commonly seen with aging or slowly progressing caries. This tubule occlusion makes the dentin more mineralized and less permeable, often giving it a more translucent or radiopaque appearance and reducing fluid flow and sensitivity. This description fits the term sclerotic dentin (dentin sclerosis). Primary dentin is the dentin formed before eruption, and secondary dentin is dentin laid down after eruption in response to stimuli but not specifically defined by tubule mineralization, so they don’t describe this fully calcified, aging-associated change.
