Abstract:
The degree of conversion (DC) and the compressive strength (CS) are important indexes of composite resin. This study is aimed to investigate the effects of diphenyliodonium on the DC and the CS of the light-curing composite resin. Different amount of diphenyliodonium hexaflourophosphate was added to the light-curing composite resin; the concentrations of diphenyliodonium hexaflourophosphate were 0 wt%, 0.5 wt%, 1.0 wt%, 2.0 wt%, 3.0 wt% and 4.0 wt% of the reisin matrix (containing BisS-GMA and TEGDMA) respectively. The DC and the CS of the six aforementioned groups of the composite resin were measured by the Fourier transform infrared spectroscopy and the tensile strength of machine, respectively. Diphenyliodonium hexaflourophosphate can improve the DC and CS of the light-curing composite resin. When the concentration is 2.0 wt%, the DC and CS can achieve better performance.
