Which statement is true regarding caries distribution in children?

• A. Pits and fissures account for about 88% of caries
• B. Smooth surfaces account for 88% of caries
• C. Root surfaces account for 88% of caries
• D. Interproximal areas account for 88% of caries

Answer: (A)

Most caries in children start in pits and fissures because these deep, irregular grooves on chewing surfaces trap plaque and are hard to clean. The anatomy provides many niches where bacteria produce acids, leading to demineralization that begins in these grooves and progresses before adjacent smooth surfaces are affected. That combination—retentive pits and fissures plus challenges in brushing—explains why a large majority of pediatric caries occur there. In contrast, root surfaces are not typically exposed in younger children, and while interproximal areas do develop caries, they don’t account for the same share as fissures. So the statement reflecting pits and fissures as the main location, around 88% of caries, aligns with common patterns seen in children.
