Popis: | Background. The use of bleaching agents might result in microstructural changes in tooth structure andin restorative materials. This study compared the effects of bleaching with %15 carbamide peroxide and%35 hydrogen peroxide on the flexural strength of Cention N restorative material using the self-curedand dual-cured polymerization modes. Methods. Sixty bar-shaped samples of Cention N restorative material were included in this in vitrostudy and assigned to three groups (n=20) randomly: control, bleaching with %15 carbamide peroxideand bleaching with %35 hydrogen peroxide. Each group was divided into two subgroups: samplespolymerized in the self-cured mode and samples polymerized in the dual-cured mode. Then the flexuralstrengths of the samples were determined. Two-way ANOVA was used to compare flexural strengthsbetween the three groups in two polymerization modes, followed by post hoc Tukey test. Statisticalsignificance was defined at PResults. The difference in the mean flexural strength was significant in terms of the bleaching regimen(PConclusion. The application of %15 carbamide peroxide and %35 hydrogen peroxide bleaching agentsdecreased the flexural strength of Cention N restorative material. Irrespective of the bleaching regimen,there was no significant difference in the flexural strength of Cention N between the self-curing anddual-curing polymerization modes. |
