Description

The purpose of this study was to evaluate the effect of one-day storage on the bonding ability of self-adhesiveresin cement (SARC, RelyX Unicem Aplicap: 3M ESPE, G-Cem Capsule: GC, Clearfil SA Luting: KurarayMedical) and adhesive resin cements (ARC, ResiCem: Shofu, Clearfil Esthetic Cement: Kuraray Medical) tozirconia (Lava: 3M ESPE) and alumina (Vita In-Ceram Alumina, GC) with a composite inlay system (Z250, 3MESPE), and on the flexural strength and flexural modulus of these cements.<BR>The shear bond strength of SARCs and ARCs to zirconia (Lava) after one-day storage was improved comparedwith the immediate condition. The shear bond strength to alumina (Vita In-Ceram Alumina) of SARCs after one-day storage was improved compared with the immediate condition, however, the case of ARCs did not show thispattern. This was caused by the development of the resin cement/zirconia (or alumina) interaction and the resincement itself, because of the increasing flexural strength and flexural modulus.
