Which type of caries occurs on the proximal surfaces?

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

Answer: (A)

This question is about where caries develop on tooth surfaces. The spaces between adjacent teeth are the proximal surfaces. Decay that begins in these contact areas is called proximal caries. Plaque tends to accumulate in the contact zones and cleaning is harder there, so caries often starts there and is typically detected between teeth, sometimes best on radiographs as a lesion between adjacent crowns. Root caries affect exposed root surfaces, often near the gumline. Cervical caries occur at the cervical region near the CEJ on facial or lingual surfaces. Occlusal caries develop on the chewing surfaces of posterior teeth where pits and fissures are. Therefore, the type that occurs on proximal surfaces is proximal caries.
