Purpose:
To evaluate the bond strength of 3 resin cements on ceramic-dentin.
Methods:
Thirty sound human posterior tooth were selected for this study and the flat dentin surfaces were prepared. The specimens were divided into 3 groups(n=10) randomly, which were bonded to the CAD/CAM ceramics with RelyX ARC(etch-and-rinse adhesive), Clearfil DC Bond(self-etching resin cement) and RelyX Unicem(self-adhesive resin cement). The bond strengths were tested and the bond surfaces were observed under stereoscopic microscope.SPSS 11.0 software package was used for statistical analysis.
Results:
The shear bond strength of RelyX ARC and Clearfil DC Bond was (15.90±6.15)MPa and (14.41±5.07)MPa, respectively. The shear strength of RelyX Unicem was(23.29±7.39)MPa, significantly higher than the others.The shear strength between the three resin cements was significantly different (P<0.05).
Conclusion:
Clearfil DC Bond and RelyX Unicem can achieve a successful bond on CAD/CAM ceramic crowns.

For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in ASTM C...
