FT-Raman spectroscopy study on the effect of ceramic fillers in P(EO)LiBETI

Abstract The application of dental restorative composites has opened wide possibilities in modern dentistry. The dental pastes studied in this work consist of a dimethacrylate-based matrix to which silica or ceramic fillers are added to improve their mechanical properties, colour stability and aesthetic appearance. The pastes were cured through free-radical polymerisation with visible light and were subjected to accelerated aging in the laboratory. The degree of monomer conversion with photo-curing, studied with FTIR and FT-Raman spectroscopy, was 42 ± 2% on average, which further advanced after aging to 56 ± 4%. The samples exhibited fluorescence at various intensities, which declined by the curing and aging procedures by a maximum of c. 20%, depending on the type of fillers present.

The adaptation and construction of an environmental chamber suitable for FT-Raman spectroscopy is described for the recording of Raman spectra of specimens at temperatures from 25 to 125 °C while exposed to different controlled synthetic atmospheric conditions. Test spectra were obtained from sulfur to illustrate the stability and applications of the system. The α rhombic/β monoclinic phase change in sulfur was monitored as a function of time, and bands sensitive to this phase change have been identified.
