One aspect of the present invention relates to a dental fluoroaluminosilicate glass powder, a 50th percentile volume diameter of which is 5.0 &#x3bc;m or more and 9.0 &#x3bc;m or less, and a 10th percentile volume diameter of which is 2.4 &#x3bc;m or more.

Dental fluoroaluminosilicate glass powder

A dental treatment material includes: 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.

Dental treatment material and dental treatment material kit

A dental glass includes: phosphorus; sodium and/or potassium; and calcium, wherein the dental glass contains, in terms of oxide, phosphorus (PO) by greater than or equal to 40% by mass and less than or equal to 70% by mass, sodium and/or potassium (NaO, KO) by greater than or equal to 20% by mass and less than or equal to 40% by mass, and calcium (CaO) by greater than or equal to 1% by mass and less than or equal to 20% by mass, and wherein the dental glass does not substantially contain silicon and aluminum.

Dental glass and dental composition

A dental polymerizable composition including a glass powder and a (meth)acrylate is provided. The glass powder includes zinc, silicon, and fluorine and is substantially free of aluminum.

Dental polymerizable composition

In one aspect of the present invention, a dental cement contains a glass powder, wherein the glass powder contains zinc, silicon, and fluorine and does not substantially contain aluminum.

Dental cement

In one aspect of the present invention, a dental glass powder contains zinc, silicon, and fluorine and does not substantially contain aluminum.

Dental glass powder

Provided is a filler for dental glass ionomer cements, the filler to a surface of which a compound(s) having a carboxyl group(s) is/are bound via a silicon atom, for the purpose of providing: a filler suitable for dental glass ionomer cements that can provide a hardened cement having a high strength by being mixed with a dental glass ionomer cement composition, the filler that can be easily manufactured from a general inorganic powder as a raw material; and a manufacturing method of the filler for dental glass ionomer cements. The manufacturing method includes binding a carboxylic acid having an unsaturated double bond(s) exclusive of a (meth)acrylate compound to an inorganic powder whose surface is treated with a silane coupling agent having an unsaturated double bond(s).

Filler for dental glass ionomer cement and method for manufacturing the same

Provided is a fluoroaluminosilicate glass powder that can provide a dental glass ionomer cement hardened body excellent in acid resistance, the glass powder including sodium and potassium which have an effect of lowering the reflective index of glass. A mass ratio of potassium to sodium in the component is in the range of from 1.2 to 1.9 in terms of oxide.
