The Effect of Cavity Configuration on the Mechanical Properties of Resin Composites.

The objective of this study was to evaluate the effect of configuration of cavity on the mechanical properties such as flexural strength and elastic modulus of resin composites. The materials used were $Clearfil^{TM}$ AP-X(Kuraray, Japan) and $Esthet-X^{TM}$(Dentsply, USA) as resin composite. Dentin-bonding systems used in the study were $Clearfil^{TM}$ SE Bond(Kuraray, Japan) and Prime ＆ Bond $NT^{TM}$(Dentsply, USA). The specimens were prepared as 6 groups with 2 control groups and 4 experimental groups.(omitted)
