目的:比较Tetric EvoCeram、Venus和Filtek3种光固化复合树脂大体积充填的固化深度和显微硬度. 方法:根据ISO4049-2000标准测量3种复合树脂的固化深度,并使用维氏显微硬度仪测量其显微硬度.测试结果用单因素方差分析和Tukey post hoc HSD进行分析.结果:3种复合树脂大体积充填的固化深度之间没有显著差异,且均大于4 mm.但表面维氏硬度之间三者均有显著差异(P<0.05),从大到小依次为:Tetric EvoCeram组>Filtek组>Venus组.结论:综合两方面指标,Tetric EvoCeram树脂机械性能较高.

Objective:To determine the post-cure depth of cure and Vickers microhardness of 3 kinds of bulk fill resin composites through using Vickers hardness. Method:3 bulk fill composite materials were examined:Tetric EvoCeram(R) Bulk Fill,Venus(R) Bulk Fill,and FiltekTM Bulk Fill. According to ISO 4049~2000,the post-cure depths of cure for 3 com-posite materials were evaluated. The Vickers hardness was also measured by Vicker's hardness gauge. Data were analysed by one-way ANOVA using Tukey post hoc tests (α=0.05). Result:There were no statistically significant differences on the depths of cure for 3 composite materials which were all above 4 mm ,complying with manufacturers' claim. There were sta-tistically significant differences on the Vickers microhardness for composite materials ,the order as follows:Tetric EvoCeram> Filtek > Venus. Conclusion:The mechanical properties of Tetric EvoCeram are higher,and we should choose materials with different mechanical properties in the clinical operation according to clinical need.
