摘要
A glass ionomer-based fluoride applying material that is able to release 200 g/cm2 or more, and preferably 300 g/cm2 or more of a fluoride ion until 30 days after immersing a set material thereof in distilled water kept at 37 C., is provided, which contains a fluoroaluminosilicate glass powder, a polycarboxylic acid and water as major components, the fluoroaluminosilicate glass powder accounting for 5 to 70% by weight of the whole, preferably containing, as constitutional elements, 10 to 20% by weight of Si, 10 to 20% by weight of Al, 1 to 20% weight of F, and 5 to 30% by weight of Sr, and additionally, at least one of Na, K, Mg and Ca, and preferably containing Na in an amount of 3 to 15% by weight.
