RESUMO:

Objective: To evaluate the influence of the addition of a polymerization catalyst (diphenyl iodonium hexafluorophosphate - DFI) to a resin-modified calcium hydroxide cement in physical and biological properties. Materials and methods: Ultra-Blend plus calcium hydroxide cement was used. For inclusion of DFI, four groups were created according to different concentrations: control group (G0) without inclusion of DFI; addition of 2% DFI (G1); addition of 4% (G2) and 8% DFI (G3). The degree of conversion (DC), polymerization depth (PD), water sorption and solubility, hydroxyl release (HR), flexural strength (FS) and elastic modulus (EM) were evaluated. Cytotoxicity will be evaluated further. Data were analyzed using one/two-way ANOVA and Tukey's test (p <0.05). Results: For DC, the percentages of 2% and 8% presented the highest values, while 0% and 4% were statistically similar. For PP 8% was highlighted between the groups. For FS, the 2% group presented greater FS, while the groups with 4% and 8% were statistically similar. In EM, the percentages of 2% and 8% were statistically higher in the 4% group and the 0% in the lowest group. In the Sorption, the values were expressed in a similar way, whereas in Solubility the percentage of 0% was significantly greater than the other groups. In LH, the groups were statistically similar. Conclusion: The groups with the addition of DPI had the physical and biological properties superior to the control group. The concentration of 2% was better for most of the properties analyzed.
