Abstract：Objective To compare marginal microleakage of class II restoration with four composite resins under in vitro con-ditions.Methods 30 molars without caries were selected.In each tooth,4 cavities of class Ⅱ were prepared and filled with 4 composite resins:Filtek Z350 Flowable,Filtek Z350,SDR and TetricN-Ceram Bulk Fill.All filled teeth were thermocycled for 500 times and were then immersed in basic fuchsine solusion for 24 h.The depth of methylene penetration was measured under stereomicroscope.Results Marginal microleakage value of SDR was smallest,followed by Filtek Z350 Flowable,TetricN-Ce-ram Bulk Fill,Filtek Z350,and the differences were statistically significant(P<0. 05 ).Conclusion Compared with the other composites,SDR showed significantly less marginal microleakage.
