Abstract
Polymerization shrinkage of composite resin is closely related to direct or indirect restoration failure. Many studies have reported that curing mode affects polymerization, but few studies have reported whether polymerization shrinkage is affected by the shade of the dual-cure core build-up resin. Therefore, the purpose of this study is to compare the polymerization shrinkage of a dual-cure core build-up resin according to shade and curing mode. A dual-cure core build-up resin (Dual Core, Vericom) was selected and the specimens were prepared using either natural (A3) or blue shade of 6 mm diameter and 0.5 mm thickness. The specimens were either light-cured or self-cured and polymerization shrinkage was measured using a modified bonded disc method for 1,800 seconds (n=7). Polymerization shrinkage data were analyzed using two-way ANOVA and Tukey honestly significant difference at α=0.05. No statistically significant difference in polymerization shrinkage was observed between the natural shade (3.87%±0.31%) and blue shade (3.85%±0.37%). However, polymerization shrinkage in light-curing mode (4.10%±0.14%) was significantly higher than that in selfcuring mode (3.63%±0.31%). In conclusion, polymerization shrinkage of the dual-cure core build-up resin tested in this study was not affected by shade but by curing mode.
