Which statement is NOT a location-based caries type?

Which statement is NOT a location-based caries type?

• A. Root caries
• B. Occlusal caries
• C. Systemic caries
• D. Proximal caries

Answer: (C)

Caries classified by location describe where the lesion sits on the tooth. Root caries occurs on exposed root surfaces, occlusal caries on the chewing surfaces (pits and fissures), and proximal caries between adjacent teeth. Systemic caries, on the other hand, refers to caries related to systemic factors rather than a specific tooth surface area, so it isn’t a location-based category. That’s why it’s the statement that does not belong with the others.
