Abstract
Fluoroaluminosilicate dental cement glasses are treated with an aqueous silanol treating solution and optionally with an additional organic compound. The treated glasses form cements with improved strength. The silanol can be ethylenically-unsaturated and can contain acidic groups, and, if so, is novel in its own right.
