Description
The purpose of this study was to evaluate the mechanical properties of an experimental PMMA resin cement PRC-01 (PRC). Film thickness, flexural strength and tensile bond strength to both enamel and dentin were compared with three commercially available resin cements: Multibond (MB), Super-Bond C&B (SB), and Super-Bond Quick (SBQ). Film thickness and flexural strength (three-point bending test) were measured according to ISO 4049. In addition, the film thickness affected by working time was measured after0, 1, 2and3minutes. The tensile bond strength to both enamel and dentin substrate of bovine teeth were measured after5minutes, 10minutes and 24hours respectively. The results were as follows. The film thickness of all cements met the ISO4049standard. Only PRC showed no increase in film thickness after3minutes. MB showed the lowest value in the modules in bending, while the other three cements showed no statistically significant difference. SBQ showed the lowest value in the modules in bending, while the other three cements showed no statistically significant difference. PRC showed high tensile bond strength to both enamel and dentin after5minutes, which was similar to that of MB. All cements showed no statistically significant difference in the tensile bond strength after24hours. The results indicate that PRC has good mechanical properties.
