Abstract
The aims of this study were to evaluate the material properties of the recently developed dual-cured core
resin (Experimental product, EP, Meta Biomed Inc., Cheong-won-gun, Korea) and to compare it with other
commercial products (LuxaCoreⓡ-Dual, DMG, Hamburg, Germany; MultiCoreⓡ flow, Ivoclar Vivadent,
Liechtenstein). Flexural strength and radio-opacity were tested according to ISO 4049 and surface
micro-hardness, fluoride release, and cuttability were also evaluated. The data were analyzed with one-way
ANOVA and independent t-test(p=0.05) using PASW 17.0 (SPSS Inc., Chicago, U.S.A.). The flexural strength
of EP was higher than LuxaCore in both light-curing and self-curing methods(p<0.05). The flexural
strength of EP was not significantly different between light-curing and self-curing method(p>0.05). The EP
showed the lowest surface micro-hardness among the test groups(p<0.05). For fluoride release, EP was
higher than MultiCore(p<0.05). There was no significant difference between EP and LuxaCore(p>0.05). The
radio-opacity of EP was higher than LuxaCore(p<0.05). There was no significant difference between EP and
MultiCore(p>0.05). The cuttability of EP had no significant differences among the groups(p>0.05). From the
results of this study, EP is a suitable material to be used in clinical fields as a core material.
