PROBLEM TO BE SOLVED: To provide a microgel for oral cavity, which efficiently supplies a fluoride ion to tooth surfaces simply and safely.SOLUTION: The microgel for oral cavity contains a fluoride compound and agar. The microgel is liable to adsorb on tooth surfaces and hardly drips, is easily penetrated into between teeth and between teeth and gum, has a high elution degree of dispersion of fluoride ion and supplies a fluoride ion to tooth surfaces all over in high efficiency.COPYRIGHT: (C)2010,JPO&INPIT【課題】簡便かつ安全に、歯の表面に効率よくフッ化物イオンを供給することができる口腔用ミクロゲルの提供。【解決手段】フッ素化合物及び寒天を含む口腔用ミクロゲルを提供する。当該ミクロゲルは、歯の表面に吸着しやすく垂れにくく、歯と歯の間あるいは歯と歯茎の間に容易に侵入でき、フッ化物イオンの分散溶出度が高く、フッ化物イオンを高効率に歯の表面のすみずみにまで供給できる。【選択図】なし
