“…Lower microleakage score in Vertise Flow group could be associated with this less enamel thickness of gingival margin. However, in another study [11], researchers found higher microleakage values at gingival margin than occlusal margin, but the difference was not statistically meaningful. It has been reported that Vertise Flow takes hygroscopic expansion, and this might improve the polymerization leakage/shrinkage of the material [16].…”

Abstract. Purpose: This in vitro study evaluated the microleakage of glass carbomer (Glass Fill, GCP Dental, Vianen, Netherlands), resin-modified glass ionomer (Fuji II LC, GC, Japan) and selfadhering flowable composite (Vertise Flow, Kerr, USA) materials. Materials And Methods: Class V cavities were prepared in the occlusal margin of enamel and gingival margin of dentin on both buccal and lingual surfaces of 45 human molar teeth and restored with self-adhering materials according to manufacturers' directions (n=15). The specimens were immersed in 2% basic fuchsine dye at 37ºC for 24 hours. The teeth were sectioned into two pieces buccolingually in an occlusoapical direction and evaluated for microleakage using a stereo microscope (30×) and the degree of microleakage was evaluated using specific scoring criteria. The data were analyzed using KruskalWallis, Mann-Whitney U, and Wilcoxon signed-rank tests. Results: When the self-adhering materials were compared, Glass Fill showed the highest leakage scores but was statistically different from only Vertise flow in the gingival surfaces (p<0.05). In the occlusal surfaces all tested selfadhering materials exhibited similar degrees of microleakage at the enamel margins (p>0.05). Conclusion:Glass Carbomer based self-adhering material showed more microleakage than resin based self adhering materials in the gingival surfaces, but in the occlusal surfaces all of the tested materials showed good performance.

“…Although, it sounds nice of self-bonded flowable composite, in studies high water absorption was demonstrated regarding this material [9,10]. On the other hand, Bektas and et al [11] demonstrated statistically higher shear bond strength and lower microleakage scores in Vertise Flow when used with a bonding system.…”

“…Vichi et al 18) reported that VF showed lower bond strengths to dentin and enamel, but superior marginal sealing ability in comparison with all-in-one adhesive systems. Studies examining the physical properties [19][20][21] , bond strengths, and marginal microleakage 16,22) of self-adhering composites have been published, but no reported study has investigated the bonding effectiveness of this simplified restorative material to calcium silicate-based materials. The placement of a restorative material with no compression force over a calcium silicate-based material without a separate adhesive may eliminate the adverse effects of adhesive application and limit handling errors.…”

“…Mainly used as liner or as repair material, they could also be applied as filling material in conservative preparations (2). The current novelty in adhesive dentistry is the development of self-adhesive flowable composites (SAFCs) to reduce the clinical time and to decrease the technique sensitivity (3). The SAFCs formulation is based on both conventional methacrylate system and acidic monomers bonding technology derived from self-etching adhesive systems (2).…”

The aim of this study was to determine the influence of photoinitiator systems on physical-chemical properties of flowable composites. Conventional (CFC), composed by bisphenol-glycidyl dimethacrylate (BisGMA)+triethyleneglycol dimethacrylate (TEGDMA), and self-adhesive (SAFC), composed by BisGMA+TEDGMA+bis[2-(methacryloyloxy) ethyl] phosphate (2MP), flowable composites were developed. Five photoinitiator systems were tested: camphorquinone (CQ), ethyl-4-dimethylaminobenzoate (EDMAB), diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (TPO), phenylbis (2,4,6-trimethylbenzoyl)phosphine oxide (BAPO), CQ+EDMAB+TPO and CQ+EDMAB+BAPO. A two-peak LED was used; degree of conversion (DC) and the maximum polymerization rate (RP max ) were determined by nearinfrared spectroscopy. For the yellowing degree a spectrophotometer was used. Water sorption (Wsp) was obtained after 30 days of water storage (n=5). Data were submitted to two-way analysis of variance and Tukey's test (α=0.05). BAPO presented the highest DC and RP max values for both series. SAFCs presented lower DC and RP max for CQ+EDMAB-based materials. Greater yellowing was observed for SAFCs compared with CFCs, except for BAPO. Greater Wsp was observed for SAFCs compared with CFCs. The photoinitiator did not influence Wsp for CFCs, but TPO and BAPO presented the highest Wsp in SAFCs. The photoinitiator system affected differently the physical-chemical properties of CFCs and SAFCs.
