“…reported that silorane-based composite materials exhibited less polymerization shrinkage, resulting in reduced cuspal deflection. 11 New materials that have been recently marketed are called bulk-fill resin composite materials. The manufacturers claim that these materials produce less polymerization shrinkage when compared with traditional composites, 12 consequently reducing the cuspal deflection.…”

The present study investigated the effect of three high-viscosity bulk-fill resin-based composite materials on cuspal deflection in natural teeth. Thirty-two sound maxillary premolar teeth with large slot mesio-occlusal-distal cavities were distributed into four groups (n=8). Three groups were restored with bulk-fill resin composite materials (Tetric EvoCeram Bulk Fill, Ivoclar Vivadent, Schaan, Liechtenstein; x-tra fil, VOCO, Cuxhaven, Germany; and SonicFill, Kerr, Orange, CA, USA) in a single 4-mm increment. The conventional composite group, Filtek Z100 (3M ESPE, St Paul, MN, USA), was used to restore the cavities in 2-mm increments. Cusp deflection was recorded postirradiation using a Nikon measurescope UM-2 (Nikon, Tokyo, Japan) by measuring the changes in the bucco-palatal widths of the teeth at five minutes, 24 hours, and 48 hours after completion of the restorations. Cuspal deflection was significantly higher in the conventional composite than in the Tetric EvoCeram Bulk Fill ( p=0.0031), x-tra fil ( p=0.0029), and SonicFill Bulk ( p=0.0002) groups. There were no significant differences in cuspal deflection among the three bulk-fill materials (all p<0.05). In conclusion, all the investigated bulk-fill resin composites exhibited cuspal deflection values that were smaller than those associated with a conventional incrementally placed resin composite.

“…16,17 Marginal adaptation, which depends on poly merization shrinkage and resulting stress, should be assessed at baseline because both shrinkage and resulting stress take place during the placement of the restoration. 18 Other clinical factors, such as wear and the integrity of the adhesive interface, may have induced changes in marginal adaptation over 18 months. Siloranes are inherently hydrophobic and are a combination of siloxane and oxirane chemical moieties on each monomeric unit, where the siloxane provides a hydrophobic and chemically stable backbone, and the oxirane provides reactive groups that allow polymerization.…”

The silorane-based resin composites have low polymerization shrinkage and stress, good stability in aqueous environments and insolubility in biological fluid stimulants compared with conventional dimethacrylate based composites. The aim of this study was to clinically evaluate the performance of silorane-based resin over a period of 18 months. The study was conducted in ten posterior restorations performed with silorane. Clinical evaluations were done periodically to evaluate the success of the restorations using predefined criteria. Eight out of ten restorations fulfilled all criteria up to 18 months. Two restorations had marginal chipping of the composite material. From this short-term clinical study, it can be concluded that siloranes can be used as an alternative to other posterior restorative composites. Further research over longer periods with larger samples are required to substantiate the current observations.

“…This composite resin can only be used by its own self-etch adhesive system. 3 Silorane is obtained from the reaction of oxirane and siloxane molecules. SBC exhibits low polymerization shrinkage due to the ring-opening oxirane monomer and increases hydrophobicity due to the presence of siloxane species.…”

Background. Mineral trioxide aggregate (MTA) is a material that has recently gained popularity in the application of the vital pulp therapy. Along with the increasing use of MTA to this end, the permanent restoration material to be placed on MTA has become a significant issue. The aim of this in vitro study was to investigate the bond strength of the novel low-shrinkage silorane-based composite resin (SBC) to MTA. Methods. Twenty acrylic blocks filled with MTA were prepared for this study. SBC was the test group and methacrylate-based composite resin (MBC) was used as the control group. Shear bond strength test was performed to determine the bond strength. The surfaces of broken samples were evaluated under a stereomicroscope and grouped as adhesive, cohesive and mixed. Data were examined by statistical analysis. Results. Statistical analysis revealed that SBC exhibited higher shear bond strength than the control group. It was observed that most of the failures in the test group were of cohesive type within MTA. Conclusion. Based on the results, SBC showed higher shear bond strength than the control group; however, clinical follow-up is needed to evaluate the clinical success.
