dental fluoride

What is the recommended fluoride concentration in water for prevention of dental caries?

• 2.5 to 3.0 ppm

• 1.8 to 2.2 ppm

• 0.3 to 0.6 ppm

• 0.7 to 1.2 ppm

What is the role of topical fluoride in preventing tooth decay?

• Topical fluoride strengthens cementum

• Topical fluoride strenghthens enamel

• Topical fluoride is enhances bacterial growth

• Topical fluoride helps in enamel demineralization

What is the ideal fluoride concentration in toothpaste for effective prevention?

• 3000-3500 ppm

• 500-750 ppm

• 1000-1500 ppm

• 2000-2500 ppm

What are the potential risks associated with excessive fluoride concentration in prevention?

• Dental fluorosis, skeletal fluorosis, and other health issues

• Increased immunity to dental issues

• Enhanced bone strength

• Improved cognitive function

How does fluoride prevent demineralization of tooth enamel?

• Fluoride increases the risk of demineralization

• Fluoride promotes remineralization of tooth enamel.

• Fluoride causes discoloration of tooth enamel

• Fluoride weakens tooth enamel

What is the recommended fluoride concentration in mouth rinses for prevention?

• 0.1% sodium fluoride

• 0.5% sodium fluoride

• 0.02% sodium fluoride

• 0.05% sodium fluoride

How does fluoride aid in remineralization of tooth enamel?

• Fluoride attracts calcium and phosphate ions to form fluorapatite, a stronger compound that helps repair and strengthen weakened enamel.

• Fluoride dissolves enamel instead of remineralizing it

• Fluoride inhibits the absorption of essential minerals by enamel

• Fluoride weakens the bond between enamel and dentin
