Photo-induced polymerization of dental materials
Despite the improvements in preventive measures, dental cavities remain a major public health problem. One material to fill teeth affected by cavities is resin-modified glass ionomer cement (RMGIC), which undergoes a polymerization reaction upon light illumination. Proper polymerization of the resin component is vital to achieve the necessary strength of the filling. To fully understand this process, it is important to understand how the photo-initiation affects proton mobility in RMGICs. Therefore, we propose to measure QENS spectra of a specific RMGIC (“Hema”) as well as of its liquid precursor (“liquid Hema”) in the dark and after photo-illumination, respectively, on the backscattering spectrometer IN16b.
