31 cards
Card 1
Question: What is salt fluoridation, and which salts are used to fluoridate it?
Answer: It involves adding a mixture of potassium fluoride and sodium fluoride to household or table salt to achieve a specific fluoride concentration.
Card 2
Question: What is the target fluoride concentration in salt for fluoridation programs?
Answer: It is added to achieve between 250 and 300 mg of fluoride per kg of salt; the minimum acceptable level is 200 mg/kg.
Card 3
Question: What salt fluoride concentration produces salivary fluoride levels similar to those from fluoridated water at 1 mg/L?
Answer: Salt with approximately 250 mg of fluoride/kg produces salivary levels similar to those from fluoridated water at 1 mg/L.
Card 4
Question: What is the relationship between salt fluoride concentration and caries reduction?
Answer: Caries reduction depends on the concentration: 200 mg/kg yields less reduction than 250 mg/kg, and the best results were observed with 350 mg/kg.
Card 5
Question: What is the minimum level of regular fluoridated salt consumption required for a significant effect on caries prevention?
Answer: Regular and continuous consumption of household salt with 250 mg of fluoride/kg significantly reduces caries in both deciduous and permanent dentition
Card 6
Question: Are adverse effects like dental fluorosis observed with fluoridated salt at 200–350 mg/kg?
Answer: No adverse effects or significantly mottled enamel were observed in the experimental groups with 200, 250, or 350 mg F/kg compared to the control grou
Card 7
Question: How are compliance and potential excessive fluoride intake monitored in fluoridated salt programs?
Answer: Urine is used as a biomarker to monitor compliance with salt fluoridation and detect excessive fluoride intake.
Card 8
Question: What evidence exists regarding the effectiveness of fluoridated salt in reducing caries?
Answer: Studies in Colombia, Hungary, and Switzerland showed caries reductions similar to those from fluoridated water, with reductions of around 50% in the n
Card 9
Question: What criticism was mentioned regarding the effectiveness of fluoridated salt?
Answer: It was noted that its effectiveness is questionable because no randomized clinical trials have been conducted to prove its efficacy.
Card 10
Question: In which countries or regions is fluoridated salt available and widely used?
Answer: It is available in several countries: ~12 in the Americas, 8 in Europe; extensively used in Europe, Central and South America, with recent adoptions i
