Aim: The aim of this study is to compare marginal sealing of three different bulk-fill composite restorations of Class II cavities under in vitro conditions. Materials and Methods: Thirty human extracted pre-molars were divided into three groups of 10 each. Class II cavities were prepared and restored using Filtek Bulk Fill (Group I), Tetric N-Ceram Bulk Fill (Group II) and X-tra Fil Bulk Fill (Group III) composite materials. Depth of dye penetration along the lateral walls of each specimen was evaluated under stereomicroscope, and marginal gap was evaluated under scanning electron microscope. Statistical Analysis Used: In a one-way ANOVA study, statistical analysis will be done using non-parametric, Kruskal–Wallis rank-sum analysis and Chi-square test for categorical data. For all statistical analysis, probability levels of P < 0.05 will be considered statistically significant. Results: Stereomicroscopy showed no dye penetration in 90%, 70% and 30% of restorations in Groups I, II and III, respectively. The mean width of marginal gap (μm) was 1.691, 3.076 and 4.546 in Groups I, II and III, respectively. Conclusions: Under the limitation of in vitro study, Filtek Bulk Fill composite material showed least microleakage and better marginal adaptation.
