Abstract: The present disclosure provides glass compositions that include from about 20 mol % to 45 mol % of B2O3; and from about 10 mol % to about 80 mol % of one or more glass components selected from the group consisting of CaO and MgO. The glass compositions also include less than 0.1 mol % CdO. The glass compositions may include one or more of Na2O, K2O, and a phosphate source, where the B2O3 and the phosphate source total about 60 mol % or less. The glass compositions may include a source of fluoride. The glass composition may be used to desensitize dentin. The present disclosure also provides dentin-desensitizing compositions, as well as methods and uses of the disclosed glass compositions.

Abstract: The present disclosure provides glass compositions that include from 45 mol% to about 95 mol% of B203; from about 3 mol% to about 60 m ol% of one or more glass components selected from the group consisting of: K20, Na20, CaO, and MgO; and from about 2 mol% to about 45 mol% of CaF2, SnF2, NaF, KF, Na2PO3 F, or a combination thereof, where the glass includes less than 30 mol% of CaF2, SnF2, or a combination thereof. The glass includes: substantially no CuO; less than 0.1 mol% of Li20, less than 0.1 mol% of Rb2O, less than 0.1 mol% of BaO; less than 0.1 mol% of P205; less than 0.1 mol% SiO2; and less than 30 mol% of MgO. The glass composition may be used to desensitize dentin. The present disclosure also provides dentin-desensitizing compositions, as well as methods and uses of the disclosed glass compositions.

Abstract: The present disclosure provides a glass composition that include from about 50 mol % to about 95 mol % of B2O3; from about 5 mol % to about 50 mol % of one or more glass components selected from the group consisting of: Li2O, Rb2O, K2O, Na2O, SrO, CaO, MgO, and ZnO. The glass composition includes less than 30 mol % of Rb2O. The glass composition is a quaternary system. The glass composition is a particulate material that includes particles that are from about 1 to about 50 ?m in size. The glass composition loses at least 5 mass % within 24 hours when exposed to a buffered saline solution. The glass composition may be used to desensitize dentin. The present disclosure also provides a dentin-desensitizing composition.
