The adhesiveness of plastic sealers have only been studied in face-ground enamel specimens. A procedure for examining adhesiveness in naturally formed enamel surfaces is described. After treatment with varying concentrations of phosphoric acid, three naturally formed occlusal surfaces were sealed with Enamite, Nuva-Seal, and Alpha-Seal. The best adhesiveness was obtained after conditioning with 50% H3PO4, without additives. The best values were achieved with Nuva-Seal; the worst, with Enamite. Additives to the cauterizing agent distinctly reduced adhesiveness.
