ABSTRACT:
Aim: The
aim of this study was to compare the flexural and compressive strengths of a
new sonicactivated bulk-fill system (Sonicfill) with other bulk-fill resins and
a universal posterior composite resin. Materials and Methods: A low-stress
flowable base resin material (SDR), a bulk-fill composite resin (Tetric Evo
Ceram), a universal posterior composite (GC G-aenial), and the Sonicfill system
were compared. The specimens were prepared for each group following ISO
Standard 4049 (flexural strength) and ADA 27 specifications (compressive
strength). One-way variance analysis and Kruskal-Wallis tests were used to
determine the statistical differences among groups (p 0.05). Results: The
Sonicfill system presented significantly higher compressive strength than other
groups (p p > 0.001). Conclusion: Due to the
ability to place restorations with single increment and ease of use, the
Sonicfill system can be an alternative for posterior restorations.
