Aim: To compare the microleakage of Filtek bulk fill posterior and Beautifil II LS composites in Class II cavities using stereomicroscope. Materials and Methods: A total of 34 extracted teeth were randomly divided into two groups. Teeth were prepared and mounted on a plaster block. In each tooth, Class II cavities were prepared, following which the cavities were etched and bonded. In Group I, 17 teeth were restored with Filtek bulk fill posterior composite in bulk fill technique and in Group II, 17 teeth were restored with Beautifil II LS following manufacture's instructions. The samples were then thermocycled and then the tooth were immersed in 1% methylene blue for 24 h and were divided into two halves mesiodistally using a diamond disc at low speed. Then, all the sections were observed under a stereomicroscope at ×10 magnification. Results: Mann–Whitney U-test displayed a statistically significant higher mean rank among Filtek bulk fill group (mean rank = 23.09) when compared to Beautifil II LS composite group (mean rank = 11.91). Conclusion: The study concluded that in Class II restorations, Beautifil II LS showed significantly less microleakage than Filtek bulk fill posterior.
