Disadvantages of diacrilic composite resins and glass ionomers cements have stimulated research to develop hybrid materials to eliminate the downsides and take advantage of their benefits. The purpose of this study was comparative analysis of a resin composite and hybrid materials compomers sealing material used in preventive sealing by Energy Dispersive X-ray Spectrometry and Scanning Electron Microscopy (SEM).
