First claim
Opening claim text (preview).
The invention claimed is: 1. A dental treatment material comprising: a liquid dispersion of a glass powder; and an inorganic phosphoric acid aqueous solution, wherein the glass powder contains zinc, silicon, and fluorine and does not substantially contain aluminum, and wherein a content of zinc oxide (ZnO) in the glass powder is greater than or equal to 20% by mass. 2. The dental treatment material according to claim 1 , wherein the dental treatment material is a dentinal tubules sealing material. 3. The dental treatment material according to claim 1 , wherein the content of zinc oxide (ZnO) in the glass powder is less than or equal to 60% by mass. 4. The dental treatment material according to claim 1 , wherein the content of zinc oxide (ZnO) in the glass powder is less than or equal to 55% by mass. 5. The dental treatment material according to claim 1 , wherein the content of zinc oxide (ZnO) in the glass powder is greater than or equal to 23.8% by mass and less than or equal to 50.5% by mass. 6. A dental treatment material kit comprising: a container in which a liquid dispersion of a glass powder that contains zinc, silicon, and fluorine and does not substantially contain aluminum is contained; and a container in which an inorganic phosphoric acid aqueous solution is contained, wherein a content of zinc oxide (ZnO) in the glass powder is greater than or equal to 20% by mass.
