Abstract
The aim of this study was to evaluate the influence of the polymerization on shade and thickness of a silorane-based composite resin. A2, A3 and C2 shades of silorane ?based composite resin were selected. The number of photons were detected using the photodiode detector. The microhardness of the specimen was measured using a Vickers hardness at the different thicknesses. The degree of conversion (DC) of the specimens was determined using Fourier transform infrared spectroscopy (FTIR). To measure the polymerization shrinkage, a linometer was used. Data were statistically analyzed by ANOVA and Tukey’s test. In the subsurface, the incident light decreased exponentially. A2 group showed less light attenuation than the other groups(p<0.05). The microhardness of A2 group ranged 52.0-62.3 Hv on top and bottom surfaces, A3 and C2 groups were ranged 48.5-58.3 Hv and 51.6-61.5 Hv, respectively. In the DC, A3 group showed significantly lower when compared to A2 group(p<0.05). Polymerization shrinkage was 7.3-7.6μm and these were significantly similar regardless of the specimens(p>0.05). In conclusion, photons decreased exponentially with increasing specimen thickness. The microhardness and the DC of A3 group were significantly lower than other groups. Polymerization shrinkage had statistically similar values regardless of the groups (p<0.05).
