Question

1. Fluoride inhibits caries formation via
(a) by decreasing acid solubility of
enamel
O (b) bacterial inhibition
O (c) both the above
O
(d) by increasing acid solubility of
enamel​

Answer 1

by increasing acid solubility of enamel

Answer 2

Fluoride inhibits caries formation via Option (C) Both the above.

Explanation:  

• Fluoride inhibits caries formation by decreasing acid solubility of the enamel and by inhibiting bacterial growth.
• Fluoride is ingested in a small amount during tooth formation in the jaw and gets built into the enamel.
• Fluoride is concentrated in saliva that bathes the teeth.
• It also remineralizes tooth enamel to form a durable, cavity-resistant outer surface.
• Excessive consumption of fluoride can result in dental and skeletal fluorosis.
