“…The results of the present study differ from the findings of Misilli and Gönülol () who compared the sorption and solubility grades of three bulk fill composites (X‐tra Fil, Tetric N‐Ceram Bulk Fill, SonicFill) with a control material (Filtek Z250). The authors observed that the control presented higher sorption than the bulk fill composites, but the Sonic Fill resin had the highest solubility.…”

“…Similarly, the hardness at the bottom surface was higher in samples filled by the 2‐increment technique because of the shorter distance from the polymerization light of the first portion of composite (Misilli & Gönülol, ). In the present study, the samples made with two increments also underwent two photopolymerization sessions with one of them at 2 mm distance from the bottom while in the bulk fill technique, one photopolymerization session was done at 4 mm from the bottom.…”

“…0.02w?>Although previous studies (Misilli & Gönülol, ; Tekin, Figen, Atalı, Filiz, & Pişkin, ) have evaluated water sorption and solubility of regular viscosity bulk fill composites, studies that investigate the influence of incremental or bulk fill techniques on water sorption and solubility of conventional and regular viscosity bulk fill composites are lacking. In addition, an investigation of the relationship between microhardness and organic and filler content/morphology of composites on water sorption and solubility taking into account the filling technique is needed.…”

Objective To evaluate the morphology of filler particles, chemical composition, microhardness (MH), water sorption (WSp), and solubility (WSl) of a regular viscosity bulk fill and traditional composite resins. Methods Eighty samples (Ø:5 mm; height: 4 mm) were prepared according to the factors “composite” (Aura/SDI, FiltekZ250 XT/3M, Aura Bulk Fill/SDI, and Filtek Bulk Fill/3M) and “filling technique” (incremental and bulk) (n = 10). Vickers MH was measured on the top and bottom surfaces of each samples, and then WSp and WSl were obtained by means of mass gain and loss. Morphology of filler particles and chemical characteristics of composites were evaluated by scanning electron microscopy (SEM) and energy dispersity spectroscopy (EDS) in additional samples (n = 1/group). Data were analyzed using two‐ and three‐way ANOVA and Tukey's tests (p < .05). Results No significant difference was found for WSp among the groups. Comparing composites in the incremental technique, Aura bulk fill composite showed lower WSI than the other materials and in the bulk fill technique, Filtek Bulk Fill showed the lowest value. Filtek Bulk Fill showed higher MH than the other composites on the bottom surface when samples were produced by bulk filling. Conclusion The composites presented good physical properties, but the bulk fill ones showed better results for the bottom microhardness and solubility, although chemical elements and morphology were similar in general.

“…5 According to their manufacturers, they have a higher depth of polymerization, which could eliminate the need for layering. They are also claimed to generate low polymerization shrinkage stresses, 6,7 owing to the use of modified resinfiller technologies, 8,9 that minimize the volumetric shrinkage and/or modify the visco-elastic behavior of bulk-fill composites by decreasing their elastic moduli and increasing their flow capacity. The reduction in shrinkage stresses of bulk-fill composites, if true, can result in improving the marginal integrity and the durability of the bond of composite restoration to the tooth structure.…”

Background. Bulk-fill composites were developed to simplify composite placement and minimize polymerization shrinkage stresses, which can improve gingival marginal adaptation in deep class II cavities. Objectives. The objective of this study was to compare the gingival microleakage of class II cavities restored with bulk-fill composites to that of incrementally restored ones with a conventional composite at 2 storage periods. Material and methods. Forty freshly extracted intact molars were employed. Two standardized class II slot cavities, 3-millimeter-wide buccolingually, with the gingival floor 0.5 mm below the cementoenamel junction (CEJ) and the axial wall depth of 1.3 mm were prepared in each tooth (80 cavity preparations). The prepared teeth were divided equally into 3 bulk-fill groups (Tetric EvoCeram ® Bulk Fill, X-tra Fil ® and QuiXX ®) and 1 control group (TPH Spectra ® HV). Each group was subdivided into 2 equal subgroups (n = 10) according to the storage period in distilled water (24 h and 6 months). The Adper ® Single Bond Plus adhesive was used with all the restorative materials. The cavities in the experimental groups were restored with 4-millimeter bulk-fill composites in 1 increment, while the cavities in the control group were restored with 2 increments of the thickness of 2 mm. The polymerization light was applied from the occlusal surfaces. The teeth were then immersed in 2% procion red dye solution, sectioned and examined under a stereomicroscope to determine the extent of dye penetration. The data was statistically analyzed using the Kruskal-Wallis test and the Mann-Whitney U test. Results. The Kruskal-Wallis test revealed no significant differences in the mean microleakage scores among all the groups after 24-hour and 6-month storage (p = 0.945 and p = 0.928, respectively). The Mann-Whitney U test revealed an increase in the mean microleakage scores in all the groups after 6-month storage; however, the scores were not significantly different from the means obtained after 24 h (p = 0.259 for Tetric EvoCeram Bulk Fill; p = 0.205 for X-tra Fil; p = 0.166 for QuiXX; p = 0.155 for TPH Spectra HV). Conclusions. Gingival microleakage of bulk-fill composites in class II cavities was not significantly different from that of incrementally restored ones with a conventional composite. The increase in the mean gingival microleakage of the specimens stored for 6 months was not statistically significantly different in comparison to the values obtained after the 24-hour storage period for each composite.

“…Preventing these voids becomes a more daunting task when the fillers/fibers are packed tightly together in a composite. Water sorption and solubility is also an important property of dental composite which affects its performance [11]. The objective of this research is to study the effect of silica filler particles on void content along with water sorption and solubility of resin based dental composite.…”
