What happens when the Powder/Liquid ratio of a cement decreases?

Decrease in strength, increase in flow and solubility (correct)

No change in properties

Increase in strength, decrease in flow and solubility

Increased fluoride release

What advantage does Resin-Modified Glass Ionomer (RMGI) have over Glass Ionomer Cement (GIC)?

Higher fluoride release
