ABSTRACT The present invention provides a method of preparing a shaped dental prosthetic device for use in a human mouth comprising: (1) Shaping a curable dental material into a shaped dental prosthetic device having at least two surfaces approximately perpendicular to each other, positioning said device so that one of said surfaces is substantially vertical and the other of said surfaces is substantially horizontal; said material including a polymerization intiator for said substance activatable by visible light in the range of about 400-500 nm (2) Coating said surfaces with a liquid composition which will substantially exclude air from said surfaces; said composition comprising an organic compound present in an amount of about 6 percent or more, based on the weight of said liquid composition, and having a viscosity of about 50 to about 50,000 cps said liquid composition being applied to both the substantially vertical surface and the substantially horizontal surface of said dental device in a residential layer of at least about 35 mg/dm2 on a fully dry weight basis; and (3) Applying visibile light radiation of about 400 to about 500 nm to the substantially vertical surface and to the substantially horizontal surface of the device through said composition.
