Least cariogenic among these______________?

Correct answer: D. Raw starch

  • A. Fructose
  • B. Cooked starch
  • C. Sucrose
  • D. Raw starch

Raw starch is least cariogenic because its molecules are less accessible to salivary and bacterial enzymes than cooked starch, which has been gelatinized. Sucrose and fructose are readily fermentable sugars and are more cariogenic.
