Which of the following is a risk factor for dental caries?

• A. High bacterial counts
• B. Regular dental visits
• C. Adequate fluoride intake
• D. Regular brushing

Answer: (A)

High bacterial counts in dental plaque raise the risk for caries because these bacteria ferment sugars into acids that attack and demineralize tooth enamel after meals. The more cariogenic bacteria present, the more acid is produced, tipping the balance toward decay. Protective factors like regular dental visits, adequate fluoride intake, and regular brushing help prevent caries by removing plaque, strengthening enamel, and promoting remineralization, so they are not risk factors.
