Abstract
A one-component paste-consistency dental material which cures upon contact with oral fluids intended primarily for use as a temporary restorative/cement. The formulation includes solid particles reactive with water dispersed in a hydrophobic viscous binder which, upon exposure to moisture, will solidify to a depth in excess of 8 mm measured from the surface/water contact area. The curing mechanism relies on both formation of hydrates and reaction of organic polyacids with alkaline glass or metal oxides, or the salts of metal oxides with weak acids. The resulting cured material is non toxic, resistant to deterioration in oral fluids, possesses adequate water resistance, and, optionally, may release fluoride desirable for prevention of secondary decays and alleviation of postoperative tooth sensitivity.
