Aim: To evaluate the degree of conversion, and polymerization shrinkage of silorane-based (Filtek Silorane, 3M ESPE St. Paul, MN, USA) and dimethacrylate-based (Filtek Z550, 3M ESPE, St. Paul, MN, USA) composites after preheating procedures.
Materials and Methods: For assessing the degree of conversion, three cylindrical specimens for each experimental condition (4 °C, 21 °C, 39°C, 55°C) were built in a Teflon mold and after 24 h storage a Fourier transform infrared spectrometer was used for analyses. The volumetric polymerization shrinkage of the composite resins was determined using a video imaging device (n=10). Student’s t-test and one-way ANOVA with Tukey multiple comparison tests (p< 0.05) were used to assess the results.
Results: In terms of all tested parameters and temperatures, Filtek Z550 showed higher values than Filtek Silorane (p< 0.05). The preheated groups showed a better degree of conversion for both of the composite groups. Preheating procedures did not significantly alter volumetric polymerization shrinkage values of the tested composite groups (p>0.05).
Conclusion: Preheating caused a higher degree of conversion for silorane-based and dimethacrylate-based composites. Preheating of both silorane-based and dimethacrylate-based composites prior to polymerization may be beneficial to enhance degree of conversion.
