Spectroscopic investigations of new glass-ionomer dental cements

Emission spectroscopy has been used to study conventional and resin modified glass-ionomer dental cements by monitoring the integrated peak intensities of signals arising from chromium ions in the aluminium oxide matrix as a function of reaction time.;Different conventional cements were prepared by mixing Fuji II glass with various polyacids. Emission spectra were collected and analyzed. The differences of the setting reactions (due to polysalt formation) were explained based on the concentration and availability of hydrogen ions from the polyacids with different structures.;Commercially available and experimental resin modified cements were prepared and emission spectra were collected to compare the different setting reactions (due to polysalt formation) with and without light irradiation. The differences of the polysalt formation were explained based on the formation of the polymer network due to the light-induced polymerization.;Fluorescence spectra of polyacids were also collected to explain the fluorescence interference in the emission spectra.
