Which surface is typically targeted by the occlusal caries type?

• A. Occlusal
• B. Proximal
• C. Facial-lingual
• D. Root

Answer: (A)

Occlusal caries target the chewing surfaces of the back teeth, specifically the pits and fissures on the occlusal surface of molars and premolars. These grooves create plaque-retentive niches where food, bacteria, and acids accumulate, and they are difficult to clean with routine brushing. This makes the enamel under and around those fissures susceptible to demineralization and lesion initiation, often starting within the fissures before spreading. In contrast, proximal surfaces (between teeth), facial-lingual surfaces (the outer sides), and root surfaces are associated with other caries patterns, not the typical occlusal type.
