| Introduction Resin composites have been improved greatly nowadays, and many advancement has been reached. However, polymerization shrinkage is still a challenging drawback of composite resin restorations. Objectives this study was conducted with aim of comparing, in vitro, the marginal adaptation of three different, low shrinkages, direct posterior composites. Materials and Methods The following composites, Sonic fll® (nanohybrid composite), Filtek® P90 (Silorane-based composite) and Filtek® Z350 (nanofll composite) utilizing a standardized Class V cavity preparation followed by thermal cycling. Sixty human premolars prepared with standardized Class V cavities. The specimens were divided into three groups (n=20) according to the material used. All specimens were subjected to thermocycling at (5° to 55°C), then immersed in 2% methylene blue dye for 24hrs. For each group microleakage at the occlusal and gingival regions was measured by determining dye penetration using scoring system under steromicroscope at 100x. Results The statistical analysis of the results showed that, silorane-based composite exhibited the lowest microleakage, with statistical signifcant difference (p< 0.05) when compared with Sonicfll® composite and Filtek® Z350 XT nanofll composite. On the other hand, the results of this study showed non-signifcant difference between Sonic fll® composite and Filtek® Z350 XT. Also, there is a signifcant difference ( < 0.01) in dye penetration between occlusal and gingival regions within each group. Conclusion Taking into consideration the types of composites tested in this study, we recommend the clinical use of Siloran-based composite material for higher microleakage resistance and better marginal seal. | ||
