The electron-impact and methane chemical-ionization mass spectra of selected methacrylate and acrylate monomers commonly used in dental materials are reported and discussed. The two ionization modes complement each other, and together the mass spectra offer adequate information for identification purposes. The application of the mass spectral methods is demonstrated on resin-based dental materials with identification of the monomer content.
