“…Some recent randomized clinical trials showed that restorations with paste-like bulk-fill composite resins also presented satisfactory results over time 35,36 . In terms of clinical procedures, caution with the light-curing unit is extremely important, since evidences showed that stable irradiance, homogeneity of light beam and wavelength components may influence the degree of conversion, depth of cure and wear of bulk-fill composite resins depending on the type and brand of each bulk-fill material [37][38][39][40] . Indeed, a disadvantage of restoring posterior teeth with bulk-fill composite resin could be that the susceptibility to variance in the irradiance of the light-curing units was shown to be material dependent 21 .…”

Objective: This randomized clinical trial evaluated the behavior of restorations with flowable bulk-fill resin composite in posterior teeth three years after the restorative treatment. Methods: Seventeen patients (12 women, 5 men, age 23-59) were selected to have at least two failing amalgam or resin restorations replaced and/or to have a carious lesion restored. The cavities were randomly allocated to receive either the flowable bulk-fill composite Surefil SDR Flow occlusally covered with the conventional nano-hybrid composite Esthet-X HD (bulk and body technique) or filled exclusively with Esthet-X HD placed in 2 mm increments (incremental technique). A two-step etch-and-rinse adhesive was applied in all cavities. Thirty-four Class I or II restorations were performed in posterior teeth (n=17) during baseline. After 03 years, modified USPHS and FDI criteria were used to evaluate the restorations. Data were subjected to Mann-Whitney statistical analysis (p0.05). No restoration failures were observed over time. Conclusion: After 03 years of clinical service, all restorations using a flowable bulk-fill composite in posterior teeth showed an acceptable performance. Clinical Significance: The overall quality of posterior restorations made with the bulk and body technique was similar to that of restorations made with a nano-hybrid composite incrementally placed.

“…To solve this problem, the aesthetic properties were improved in the second-generation bulk-fill resins, offering a material with optical characteristics similar to conventional composite resins. Information about this new material is scarce and the depth of cure, as well as the mechanical properties has been widely questioned (Sahadi et al, 2018;Yap, Eweis, & Yahya, 2020).…”

The aim of this study was to evaluate the Knoop microhardness and the microtensile bond strength of a second-generation of bulk-fill (BF) and a nanohybrid composite resins (NH) in different thicknesses of increments. For this, ninety disks of composite resin were made for Knoop microhardness, being divided into six groups (n = 15). The Knoop microhardness obtained in each millimeter of the internal face. For microtensile bond strength, ninety restored in third molars were used, divided into six groups (n = 15). For Knoop microhardness, the Wilcoxon and Friedman test was used. For the microtensile bond strength were used the Two-way Anova test and Tukey's post-test (p <0.05). The NH resin showed higher Knoop micro hardness than BF and it was observed that hardness value decreases as increases the thickness of the resin. There was no significant difference in microtensile bond strength comparing NH and BF. However, there was a significant difference between G2 and G4 for the NH groups, with the highest and lowest bond strength values, respectively. Thus, the new generation of the bulk-fill composite resin provided lower microhardness values as the thickness of the increments increases in comparison with the nanohybrid composite resin. The microtensile bond strength does not appear to have been influenced by the type of resin, or the thickness of the increment.

“…Bulk-fill composites are also easier to manipulate, which helps to accelerate the restoration process in deep cavities (2,3). Despite these advantages, surface roughness remains a problem inherent to the material, and researchers agree that with time direct restorations performed with bulk-fill composites undergo changes in surface roughness (4)(5)(6)(7)(8).…”

Objective: This study aimed to compare surface roughness values (Ra) of different posterior composites after pH-cycling and toothbrushing simulation.Methods: Fifty disc-shaped specimens (8x2 mm) were prepared by using three bulk-fill composites [Filtek Bulk Fill Posterior (FBF), SonicFill 2 (SF), X-tra fil (XF)], a flowable [G-aenial Universal Flo (GF)], and a microhybrid composite [Filtek Z250 (Z250)]. After initial roughness (Ra 0 ) measurements were performed with a contact profilometer, the samples were subjected to a pH-cycling model for 10 days and Ra 1 values were recorded. Then, the samples were subjected to toothbrushing simulation for 4 min and final values (Ra 2 ) were recorded. From each group, a representative sample was analyzed with an optical profilometer. The values were analyzed by two-way ANOVA with repeated measures on one factor (period) followed by Tukey's test (p<0.05).Results: Significant differences were found among materials regardless of experimental periods. The lowest Ra values were determined in GF and Z250 groups. The highest value was obtained in SF, but this value was not statistically significant different from that obtained in XF group. Brushing procedure after chemical degradation led to an increase in surface roughness of all materials except FBF, which was not statistically significant. Conclusion:While Ra values showed differences depending on the materials, pH-cycling and toothbrushing simulation did not have a significant effect on these values.
