title: Delayed cementation and bond strength of dual-cure cements.
abstract: The purpose of this study was to determine whether the shear bond strength to enamel of three dual-cure resin cements is affected by delaying the time between cement mix and application. Etched, silanated Dicor cylinders were bonded to etched enamel with each cement at various time intervals: Immediately after mix, just prior to chemical set and at an intermediate time. Shear bond values were determined using the Instron. No significant differences were found among any of the cements at any of the times. The clinical implication is that as long as these cements remain fluid, there will not be a significant change in the bond strength of Dicor to enamel.
