Abstract
There is provided a fluoride-ion sustained release pre-formed glass ionomer filler comprising a powdery reaction product of polyalkenoic acid with a fluorine-containing glass, and a method of producing the same. There is also provided a dental composition containing the filler. The fluoride-ion sustained release pre-formed glass ionomer filler is long capable of releasing fluoride ions in the presence of water without involving disintegration. The dental composition of the invention is useful particularly for prevention of dental caries and like trouble.
