DENTAL FILLING METHOD AND COMPOSITION FORMED THEREBY Abstract of the Disclosure A novel dental filling system is described which permits the curing of a dental filling composition while excluding oxygen. The curable filling composition comprises (1) a free-radical polymerizable acrylate monomer, (2) a free- radical polymerization initiator and (3) an inorganic filler. This composition is used to fill a dental cavity and the exposed surface has applied thereto an aqueous solution of waterglass, which dries to a solid, essentially oxygen- impermeable coating of waterglass. After the curable com- position has cured, the waterglass coating is washed off with water.
