| 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 µm 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. |
