Physicomechanical Characterization of a Novel Resin-Modified Glass Ionomer Luting Cement Functionalized with a Phosphate Functional Monomer

Figure 10

The scanning electron micrographs of the broken CS and FS test surfaces were seen at magnifications of ×50, ×300, and ×500. A comparative analysis reveals that 2-MEP 20 (d), (e), and (f), as well as 2-MEP 30 (g), (h), and (i), exhibit a more integrated uniform and homogeneous surface structure characterized by a decrease in pore size and density, in contrast to the surface properties found in 2-MEP 0 (a), (b), and (c). The red arrows shown in 2-MEP 0, 2-MEP 20, and 2-MEP 30 indicate the presence of pores at varying concentrations.
