Patent ID: 7311521

Claim:
A device for diagnosis of enamel cavitation of an interproximal dental surface comprising: a substrate of generally rectangular shape and sufficient thickness for interproximal insertion; and an impressionable material disposed on only one surface of the substrate for contacting the interproximal surface and forming an impression thereof, wherein the impressionable material comprises a light-curable material selected from the group consisting of polyether and urethane dimethacrylate resin impression material, polyester urethane dimethacrylate, and copolymer-based temporary dental restorative material, the impressionable material being affixed to or embedded in one side of the substrate and having visco-elastic properties whereby an impression of the enamel cavitation of the interproximal surface remains on the impressionable material following removal of the substrate from the interproximal surface, and said substrate having an area free of said material for interproximal insertion between adjacent interproximal surfaces.
