“…They concluded that SFRC, like other tested bulk‐fill materials, provided acceptable values of DC and VH at 4‐mm thickness compared to conventional PFC resins. The finding of their study was in agreement with other studies in the literature …”

“…However, Fronza et al. reported that the mechanical performance of SFRC was intermediate and was not expected compared with that of other PFC materials . In fact, in their study, they used thin specimens (.5 mm) to test the biaxial flexural strength, and it is likely that the fibers were aligned perpendicular to the applied load, which significantly reduced their reinforcement capability.…”

A newly-recommended method for restoring large cavities is the biomimetic approach of using short fiber-reinforced composite (SFRC) as dentine-replacing material. The aim of the current review was to present an overview of SFRC and to give the clinician a detailed understanding of this new material and treatment strategy based on available-literature review. A thorough literature search was done up to December 2017. The range of relevant publications was surveyed using PubMed and Google Scholar. From the search results, articles related to our search terms were only considered. The search terms used were "short fiber-reinforced composite", "everX posterior", and "fiber-reinforced composite restorations". Of the assessed articles selected (N = 70), most were laboratory-based research with various test specimen designs prepared according to the ISO standard or with extracted teeth; only four articles were clinical reports. A common finding was that by combining the SFRC as a bulk base with conventional composite, the load-bearing capacity and failure mode of the material combination were improved, as compared to plain conventional composite restoration. In the reviewed studies, the biomimetic restoration technique of using SFRC showed promising characteristics, and therefore, might be recommended as an alternative treatment option for large cavities.

“…9 Nonetheless, the number of in vitro studies regarding micromechanical performance and light transmittance on BFRCs has increased exponentially in the last years. [10][11][12][13] On this regard, several studies have reported acceptable depth of cure at 4 mm, confirming manufacturers recommendations. 10,14,15 Conversely, other investigations have related that some BFRCs present adequate polymerization but only as far as 2 or 3 mm depth.…”

“…Due to the fact that clinical use of BFRCs is still incipient and long‐term clinical trials are extremely restricted, the confirmation of its effectiveness and consequent indication as a substitute for conventional resin composites is still pendent .

Objective To evaluate scientific evidence regarding depth of cure of bulk‐fill resin composites (BFRCs) and related factors. Material and Methods PubMed/Medline, Embase, Scopus, and ISI Web of Science databases were accessed from October 2016 to May 2017. Investigations published in English language, assessing depth of cure of BFRCs by microhardness test and/or degree of conversion (DC) were included. Studies using exclusively ISO 4049, employing specimens deepness less than 4 mm, as well as those not reporting exposure time and/or irradiance from light curing units (LCUs) were excluded. Results In total, 742 studies were found from which 33 were included. From 21 studies evaluating BFRCs microhardness, 10 showed acceptable bottom/top ratios (≥0.8) for all tested materials. However, material‐dependent results and non‐satisfactory bottom/top microhardness ratios (<0.8) were reported in 9 and 2 investigations, respectively. From 19 studies that assessed DC, 11 showed acceptable results (≥50%) for all tested BFRCs, while 8 studies reported material‐dependent outcomes. Overall, irradiance from LCUs ranged from 650 to 1330 mW/cm2 and exposure time from 5 to 60 seconds. Favorable depth of cure results were observed with the use of LCUs emitting irradiance ≥1000 mW/cm2 and exposure times ≥20 seconds. Conclusions High depth of cure rates by BFRCs, depends on some factors as material, irradiance and exposure time. Polywave LCUs were useful but not essential on polymerizing alternative photoinitiator‐containing BFRC. Clinical Significance LED curing devices (polywave or monowave) displaying an irradiance ≥1000 mW/cm2 and 20 seconds of exposure time are imperative to accomplish successful polymerization of most BFRCs.

“…A number of authors performed mechanical property tests of endodontically treated teeth and found that flowable composite resin exhibited a low elastic modulus, low stress behavior polymerization and good marginal integrity without compromising the depth of cure [9,15], which is indicated by the luting process of glass fiber posts with flowable resin. Furthermore, the light transmission could be affected by the material composition [16].…”

Bond strength of glass fiber posts cemented with bulk-fill flowable composite resin

This study evaluated the adhesive bond strength of glass fiber posts cemented with bulk-fill flowable resin in endodontically treated teeth, and the results were compared with those of glass fiber posts cemented with resin cement. Forty bovine incisor roots were selected and randomly divided into 2 groups (n = 20). The external surfaces of the roots were coated with a molding material. The canals were prepared, and then the fiber posts (Whitepost no. 2, FGM) were cemented with either resin cement (Allcem, FGM) (n = 20) or bulk-fill flowable resin (Opus Bulk Fill, FGM) (n = 20). Ten roots (n = 10) of each material were subjected to push-out and pull-out tests (EMIC DL 2000, Brazil) under compressive and tensile loading, respectively; a 50 N load cell and a constant crosshead speed of 0.5 mm/min was used for both tests. The testing data were analyzed using multifactorial analyses of variance two-way ANOVA and the Tukey test (α = 0.05). Two skilled operators determined the failure modes of the samples using a stereomicroscope at 40× magnification with a 2.5D analysis. For push-out bond strength, there were no statistically significant differences between the root thirds in the bulk-fill flowable resin group and those in the resin cement group (p = 0.536). However, there were statistically significant differences (p < 0.001) among the root thirds within the same group. For pull-out bond strength, there were no statistically significant differences between the groups (p = 0.739). Therefore, the bulk-fill flowable resin exhibited similar results to those of the resin cement from the same manufacturer in terms of the cementation of glass fiber posts, which suggests that bulk-fill flowable resin is a suitable alternative material for cementation. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

Characterization of Inorganic Filler Content, Mechanical Properties, and Light Transmission of Bulk-fill Resin Composites

Abstract: The bulk-fill composites investigated exhibited higher LT, independent of different filler content and characteristics. Although an increase in composite thickness reduced LT, the BFS of bulk-fill composites at deeper layers was not compromised.
