Abstract:
Objective:To compare the marginal microleakage of class V cavity restored with composite resin by 3 different methods. Methods:Class Ⅴ cavity was prepared in 36 human third molars,the teeth were randomly divided into 3 groups(n =1 2)and were repaired with common Z350 resin,pre-heated Z350 resin and Z350 resin inlay,respectively.After thermal cycling for 500 times the teeth were immersed in fuchsin solution for 24 h.Then the samples were sectioned longitudinally and examined for leakage under stereomicroscope.Results:The microleakage of cavity restoration by pre-heated Z350 resin and Z350 resin inlay was significantly low-er than that of the direct restoration with Z350 resin(P≤0.05).No significant difference was found between the groups of pre-heated Z350 resin and Z350 resin inlay.Conclusion:Marginal microleakage of Z350 resin restoration can be decreased by preheating of the resin.
