“…Moreover, in the present study, 10% polyacrylic acid was used to condition the surface of the cavity, which itself caused the partial demineralization of the dentin surface, which improved the penetration and diffusion of RMGIC to the intertubular spaces of the dentin and establishing a micromechanical bond to the dentin [33]; probably in this way, it has caused a reduction of the microleakage. However, this may not be the case with CGIC because the adhesion of CGIC which does not have a resin part to the dentin is chemical, and it can be estimated that the use of 10% polyacrylic acid has caused a decrease in the content of the minerals in the dentin, and, probably, it has a negative effect on the bond strength [34] and microleakage.…”

Objectives. One of the important features of the restorative materials is the ability to seal and prevent the microleakage. Glass ionomer cement (GIC) still exhibits some microleakage despite establishing a chemical bond to the tooth. The aim of this study was to evaluate the effect of nanographene oxide (nGO) on the microleakage of conventional (CGIC) and resin-modified glass ionomer cement (RMGIC). Methods. Thirty intact extracted molars were used. Class V cavities were prepared on their buccal and lingual surfaces. The samples randomly divided into two main groups of CGIC and RMGIC; each of them was randomly subdivided into three subgroups, including the group without nGO (control), the group with 1% nGO, and the group with 2% nGO. After restoring the cavities, they were subjected to thermocycling (1,000 cycles at 5/55°C). Two percent basic fuchsin solution was used to perform the microleakage test, and then the sectioned samples were examined by a stereomicroscope 40x. Kruskal–Wallis test, Dunn’s test, and Mann–Whitney U test were used to analyze the data ( P < 0.05 ). Results. Group CGIC + 1% nGO at the gingival margin and group RMGIC + 1% nGO at both gingival and occlusal margins had significantly less microleakage than their control groups ( P = 0.008 , P = 0.002 , P = 0.023 , respectively). Also, in these two groups, there were no significant differences between the microleakage of the occlusal and gingival margins ( P = 0.132 , P = 0.511 , respectively), while in all other groups, the gingival microleakage was significantly higher than that of occlusal microleakage. Conclusions. The addition of 1% nGO significantly reduced the gingival microleakage of CGIC and the occlusal and the gingival microleakage of RMGIC, while the addition of 2% nGO did not cause a significant reduction in microleakage.

“…In any case, it is necessary to mention that obtaining different results in different studies [31,32,34] regarding the comparison of the microleakage of CGIC and RMGIC could be due to the study design, materials used, quality of the substrates, location of the margins, and different measurement tests.…”
