Evaluation of marginal integrity of four bulk-fill dental composite materials: in vitro study.

Orłowski M, Tarczydło B, Chałas R - ScientificWorldJournal (2015)

Bottom Line: In each tooth 4 cavities of class II were prepared.The highest rating (score 0, no dye penetration) was achieved by 93.33% of the restorations made of the SDR material, 90% of restorations of SonicFill system, 86.66% of restorations of the composite Filtek Bulk Fill, and 73.33% of restorations of the Tetric EvoCeram Bulk Fill.The performed study showed that bulk-fill flowable or sonic-activated flowable composite restorations have better marginal sealing (lack of discoloration) in comparison with bulk-fill paste-like composite.

ABSTRACT

Objective: The aim of the study was to compare under in vitro conditions marginal sealing of 4 different bulk-fill materials composite restorations of class II.

Methods: Comparative evaluation concerned 4 composites of a bulk-fill type: SonicFill, Tetric EvoCeram Bulk Fill, Filtek Bulk Fill, and SDR. The study used 30 third molars without caries. In each tooth 4 cavities of class II were prepared. The prepared tooth samples were placed in a 1% methylene blue solution for 24 h, and after that in each restoration the depth of dye penetration along the side walls was evaluated.

Results: The highest rating (score 0, no dye penetration) was achieved by 93.33% of the restorations made of the SDR material, 90% of restorations of SonicFill system, 86.66% of restorations of the composite Filtek Bulk Fill, and 73.33% of restorations of the Tetric EvoCeram Bulk Fill.

Conclusion: The performed study showed that bulk-fill flowable or sonic-activated flowable composite restorations have better marginal sealing (lack of discoloration) in comparison with bulk-fill paste-like composite.

Mentions: Using a calibrated diamond bur under air-water cooling high speed handpiece, an experienced operator prepared in every tooth 4 cavities of class II to a depth of 4 mm (measured along the lateral wall), a width of 2 mm (pulpal wall), and length of 3 mm (approximal wall) (Figure 1). The margins of the cavities were finished with fine diamond bur.
