目的：对比研究不同固化方式对双固化树脂粘结剂挠曲强度的影响。方法：采用自固化和光固化两种固化方式，分别制作登泰克双固化树脂粘结剂标准挠曲试件（25mm ×2mm ×2mm），37℃水浴24h。试件在万能材料试验机上测试其挠曲强度。采用SPSS17．0进行统计分析。结果：登泰克双固化树脂粘结剂挠曲强度分别为：光固化组（114．82±13．59）Mpa，自固化组（106．6±5．99）MPa。两组间挠曲强度有统计学意义（P＜0．05）结论：不同固化方式对双固化树脂粘结剂挠曲强度产生显著影响。两种固化方式中，光固化组表现出较高的挠曲强度。“,”Objective:To compare the lnfluence of dif erent curing mode on flexural strength of dual cured resin cement.Methods:The self-cured and light-cured stardard specimens of Dentex for flexural strength tests were made.Universal material testing machine was applied to detect the flexural strength.Data were analyzed with SPSS17.0 software.Results:For the light-curedgroup,theflexuralstrengthofDentex(114.82±13.59)MPa.Fortheself-curedgroup,theflexuralstrengthofDentex(106.60±5.99)MPa,thereweresignificantdiferencebetweenthem (P<0.05).Conclusion:For dual cured resin cement,diferent curing mode exerts distinct influence on the flexural strength.Furthermore,light-cured group was showed to have bet er flexural strength.
