| 摘要 |
The invention provides a fluoride ion releasing dental composition including an inorganic powder (a); a fluoride ion releasing material (b); a monomer (c); and a polymerization initiator (d), in which the inorganic powder (a) is made of composite particles in which a layer of polysiloxane is formed on surfaces of substrate particles made of an inorganic material, and the fluoride ion releasing material (b) is at least one fluoride ion releasing material selected from the group consisting of ammonium fluoride, ammonium hydrogen fluoride, a metal fluoride, a polymer including, as a constitutional unit, a vinyl monomer having an acid fluoride group and a fluorine-containing phosphazene monomer. Since the fluoride ion releasing dental composition of this invention provides dentine with a high cariostatic property over a long period of time by gradually releasing fluoride ions, it is suitably used as a dental adhesive material, a dental filling material, a dental resin used for forming an abutment, a pit and fissure sealant, a dental coating material (manicure), a dental cement and so on.
