PROBLEM TO BE SOLVED: To solve problems that: refreshing feeling by washing mouth with a mouthwash may be sustained for a very short duration although a mouthpiece which is used in a manner where, at a bedtime, a mouthwash is pasted inside of the mouthpiece and the mouthpiece covers fake tooth, can sterilize teeth and mouth, it is more convenient, if it is not required to be used that is, it is a problem of the present invention to sustain antistaining and antibiotic properties for a long duration by direct treatment of the tooth and artificial tooth.SOLUTION: Therefore, in the present invention, titania phosphate type compound is selected as an antistaining material and antibiotic material and the titania phosphate type compound is directly pasted on the tooth and artificial tooth. Even under no light condition, the titania phosphate type compound coating surface of the tooth and artificial tooth degrades dirt and bacteria by oxidation with oxygen and moisture in the air in the mouth, resulting in usual continuous exertion of potent antistaining and antibiotic effects.COPYRIGHT: (C)2015,JPO&INPIT【課題】 洗口液を用いた口濯ぎによる清涼感の持続時間は極めて短い。また就寝時に内側に洗口剤を付け歯に被せて使用するマウスピースは歯や口内の殺菌を行うことが出来るものの、使用しなくて済むのであれば便利である。すなわち歯や義歯に直接的に施術するようにして防汚性や抗菌性を長期間持続させることを実現したい、と言うのがこの発明の課題である。【解決手段】 そこでこの発明では、防汚材や抗菌材にリン酸チタニア系化合物を選択し、このリン酸チタニア系化合物を直接歯や義歯に塗布するようにした。歯や義歯の表面にコーティングされたリン酸チタニア系化合物が、光がなくとも、口内の空気中の酸素と水分だけで汚れや菌を酸化分解して、常時強力なる防汚や抗菌の効果を発揮し続ける。【選択図】図1
