Question 2

APF, Acidulated phosphate fluoride

Answer 2

Acid softens enamel so fluoride is uptaken better. 1.23% concentration, pH is between 3.0-3.5 (greater than 4 compromises enamel uptake)

Question 3

Community Water Fluoridation

Answer 3

drinking water supply, most convenient, effective, and economical method of caries prevention; 50% reduction of caries in 1930s/40s; 1ppm and 0.7ppm

Question 4

Dosage recommendations, child’s age and amount of fluoride

Answer 4

most effective from birth to age 14,
birth-6 months: 0
6 months- 3 years: 0.25mg of 0.3ppm
3-6 y: 0.5mg of 0.3ppm or 0.25mg of 0.3-0.6ppm
6-15 y: 1mg of 0.3ppm or 0.5mg of 0.3-0.6ppm

recommended for patient with majority of composites and crowns - only 1 minute
