ABSTRACT
Objectives : To determine the marginal adaptation of 3 different bulk fill and one conventional composite in class 2 cavities Methods : Sample size being 40 extracted teeth, two standard class 2 cavities were prepared in each tooth. Teeth were randomly assigned to one of the four experimental groups (n=10; cavities=20 ). The experimental groups were Group 1 – SonicFill ; Group 2 – SDR ; Group 3 – FillUp ; Group -4 Filtek Z-350. After the finishing procedure, teeth were hydrated and immersed in silver nitrate and photo developing solution. All samples were sectioned horizontally and subjected to 30X stereomicroscopy to check the amount of microleakage. Results : All four groups showed significant difference in microleakage, however Sonic Fill and SDR showed good marginal adaptation. Conclusion : In class 2 cavities, bulk fill composites showed better marginal adaptation than traditional composite using incremental technique.
