Objective: Flowable bulk fill composite resins is one of the latest developments in the practice of dentistry in restorative dentistry applications. They have been developed to prevent the formation of polymerisation contraction and to create a stress-breaking barrier in adhesive preparations where the shape of the cavity can not be provided under ideal conditions. This study was performed to investigate the evaluation of surface purosis of 3 different brands bulk fill flowable composite resins.

Materials and Methods: Three different brands Bulk fill flowable composite resins; Surefil SDR Flow, X-tra base Flowable and Filtek Bulk Flow were used in the study. Restorations were prepared in standard 4x4 mm Teflon molds and stored in distilled water at 37 0C / 24 hours. The surface purosite of the materials was examined with a stereomicroscope (Olympus SZX-7) at 100X, 500X and 1000X magnification.

Results: When looking at the surface roughness at a magnification of 100X, Surefil SDR bulk fill flowable has the highest purosidity, and at 500X magnification, 3M Filtek Bulk Flow has the highest purosidity and at 1000X magnification 3M Filtek Bulk Flow was observed to have the highest purosidity. X-tra Base Flowable has at least a pore structure in the groups evaluated at 100X, 500X and 1000X magnification. Similar results were obtained between Surefill SDR and 3M Filtek Bulk Flow.

Conclusion: Surface porosity was detected in all groups despite today's technology and new generation composites. Surface porosity is a prominent parameter affecting the physical and mechanical properties of restorative dental materials. It may not be possible to achieve long-term clinical success in materials with surface porosity.
