Inorganic powder (a) and fluorine ion discharge characteristic substance (b) and polymerization characteristic monomer (c) and it contains with the polymerization initiator (d), the aforementioned inorganic powder (a), consists of the mixture particle where the layer which consists of the polysiloxane on the surface of the base substance particle which consists of the inorganic substance was formed, the dentistry which at least is the fluorine ion discharge characteristic substance of 1 where it is chosen from the group which consists of polymer and fluorine content hosuhuazenmonoma where at the same time the aforementioned fluorine ion discharge characteristic substance (b) designates the ammonium fluoride, hydrogien fluoride ammonium, metal fluoride and vinyl monomer which possesses the acid huruoraido basis as the constitution unit kindsThe business fluorine ion discharge characteristic composition is offered. Because the fluorine ion discharge characteristic composition for dentistry which relates to this invention in the long period of time gives high anti- characteristic in the tsu te dentine by discharging the fluorine ion gradually, the adhesive for dentistry, for dentistry it is full and it is used for ideal the filler and the resin for support stand construction of dentistry, as a small fossa fissure groove blockade material, a coating material (manicure) for dentistry and a dental cement etc.無機粉末(a)と、フッ素イオン放出性物質(b)と、重合性単量体(c)と、重合開始剤(d)とを含有し、前記無機粉末(a)が、無機物質からなる基体粒子の表面にポリシロキサンからなる層が形成された複合体粒子からなり、且つ前記フッ素イオン放出性物質(b)がフッ化アンモニウム、フッ化水素アンモニウム、金属フッ化物、酸フルオライド基を有するビニルモノマーを構成単位とするポリマーおよびフッ素含有ホスファゼンモノマーよりなる群から選ばれた少なくとも1種のフッ素イオン放出性物質である歯科用フッ素イオン放出性組成物が提供される。本発明に係る歯科用フッ素イオン放出性組成物は、フッ素イオンを徐々に放出することにより長期間に亙って歯質に高い抗齲蝕性を与えるので、歯科用接着材、歯科用充填材、歯科用支台構築用レジン、小窩裂溝封鎖材、歯科用コーティング材(マニキュア)、歯科用セメントなどとして好適に用いられる。
