Bond strength of three cements determined by centrifugal testing.
1. Each tooth preparation and crown should be used to test only one cement, since recementation will alter the bond strength associated with the second trial. 2. Recementation of a restoration should include a thorough cleaning of the preparation and the restoration. 3. Although zinc polycarboxylate cement possessed the highest bond strength, there were no statistically significant differences among the cements tested. 4. No correlation was found between bond strength and any individual property of compressive strength, tensile strength, or film thickness. 5. Values of ADA film thickness predicted the order of values of film thickness determined by a simulated clinical method.
