The logical explanation for the unique anticariogenic property of most silicate cements is______________?
Correct answer: C. The reduction in enamel solubility due to fluoride uptake by enamel
- A. That silicates show very little leakage at the margins of the restoration
- B. That beryllium flux is used in silicates
- C. The reduction in enamel solubility due to fluoride uptake by enamel
- D. Due to the high silica content
Explanation
Silicate cement releases fluoride, which is taken up by adjacent enamel and lowers its solubility in acid, explaining its anticariogenic effect. High silica content and low leakage do not account for this distinctive property.
