“…The absolute percentage of FG used in the experimental CBC was 2 wt.% calculated based on the resin matrix fraction, and this quantity corresponded to ~0.7% of the whole CBC mass. Considering that the mean solubility recently reported for two resin luting cements [ 52 ] ranged from 3.20 to 5.41 µg/mm 3 , depending on the pH value of the artificial saliva medium, it seems unlikely that the percentages used in the CBC prototype could generate any serious adverse biological effect. Further studies are necessary to establish the real risk related to the use of FG in dentistry.…”

Effect of Fluorographene Addition on Mechanical and Adhesive Properties of a New Core Build-Up Composite

et al. 2022

This study aims to develop a restorative material having such mechanical and adhesive properties that it can be used both as a reconstruction material and as a luting cement. The experimental core build-up composite (CBC) was derived from a self-adhesive cement by the modification of its chemical formula, requiring the use of dedicated dentin and ceramic primers. The adhesive properties to zirconia and dentin were analyzed with a micro-Shear Bond Strength test (mSBS). The mechanical properties were analyzed by a flexural strength test. The results were compared with those obtained for other commercially available cements and core build-up materials, both before and after addition of 2 wt.% fluorographene. The CBC obtained average values in the mSBS of 49.7 ± 4.74 MPa for zirconia and 32.2 ± 4.9 MPa for dentin, as well as values of 110.9 ± 9.3 MPa for flexural strength and 6170.8 ± 703.2 MPa for Young’s modulus. The addition of fluorographene, while increasing the Young’s modulus of the core build-up composite by 10%, did not improve the adhesive capabilities of the primers and cement on either zirconia or dentin. The CBC showed adhesive and mechanical properties adequate both for a restoration material and a luting cement. The addition of 2 wt.% fluorographene was shown to interfere with the polymerization reaction of the material, suggesting the need for further studies.
