Which statement best describes the new paradigm of dental caries?

• A. An irreversible lesion resulting from progressive demineralization of tooth structure
• B. An imbalance in the remineralization/demineralization cycle
• C. Caused solely by fluoride deficiency
• D. Caused by enamel morphology only

Answer: (B)

Caries is a dynamic disease of the dental biofilm, driven by the balance between demineralization and remineralization in the presence of acid-producing bacteria. When it’s repeatedly exposed to fermentable carbohydrates, the plaque lowers the local pH and minerals are dissolved from the enamel, creating or advancing lesions. If conditions shift toward remineralization—adequate saliva, available calcium and phosphate, and fluoride to help stabilize minerals—those lost minerals can be redeposited, arresting or even reversing early lesions. This view treats caries as a reversible process under the right conditions, rather than an inevitable, irreversible deterioration. Therefore, the statement that best describes this perspective is an imbalance in the remineralization/demineralization cycle. It’s not simply an irreversible lesion from demineralization, nor is it caused solely by fluoride deficiency or enamel morphology alone; those factors influence risk and progression but the disease hinges on the dynamic mineral exchange in the biofilm.
