“…2), and this could be attributed to the formation of sodium sulfate (Na 2 SO 4 ). This compound may have formed by the surface modification of EPAM with LAS (42). Equally important, the lesser amount of calcium (6.67 mg/L) measured in distilled water further supports LAS forming a coating on the EPAM surfaces.…”

The salient features of this study indicate that EPAM can naturally replace calcite, which is generally mined and used as a dental abrasive material. In addition, and regarding the abrasive characteristics of EPAM in reducing the surface roughness of PMMA resin specimens, this study conclusively showed that EPAM effectively reduces the surface roughness below the threshold limit value of 0.2 µm. Potentially, EPAM could reduce waste disposal problems while enabling an economic benefit from using eggshell waste material.

“…Two types of anionic surfactants, LSA surfactants, such as magnesium laureth sulfate (LSA-Mg) and calcium laureth sulfate (LSA-Ca), have also been used for the surface modification of CaCO 3 NPs. 214 However, the hydrophobicity of the modified CaCO 3 NPs was found to be very compatible with hydrophobic polymers. A more recent study revealed that the use of an anionic fluorinated surfactant Zonyl TBS appeared to be more efficient in improving the hydrophobicity of CaCO 3 NPs than the use of anionic hydrocarbon surfactants such as ABSA and LSA.…”

“…Surface-active compounds such as surfactants have been reported to improve the wettability and to enhance the mechanical properties of materials. 26,27 Moreover, the findings of this study demonstrated that an automatic polishing method is more likely than manual polishing to provide a better polished (►Table 6). The PMMA group with the highest mean average was handpolished with pumice by operator 1 (0.20 AE 0.03 µm), whereas the lowest was automatically polished with eggshell powder (0.04 AE 0.01 µm).…”

Objective The aim of this in vitro experiment was to see how the operator's manual skills, polishing equipment, and abrasive materials affected the surface roughness of denture base resins. Materials and Methods Forty polymethyl methacrylate (PMMA) specimens were created and polished by using two different polishing systems, namely hand and automatic polishing machines. Three operators hand-polished 30 of specimens with eggshell powder and pumice, while 10 were automatically polished (n = 5). A profilometer was used to determine the average surface roughness (Ra) after polishing. The Ra values for the specimens hand-polished were analyzed by using paired sample testing. The Ra values for all polished specimens were analyzed by using a one-way ANOVA. Differences between the two abrasive materials as well as the polishing system were determined by using the Bonferonni tests (p = 0.05). Results and Conclusion For the PMMA specimens hand-polished, there was a strong connection in the Ra values. There were also significant variations in the Ra values across the three operators (p < 0.001). The automated technique created a substantially smoother surface than the traditional technique (p = 0.001). The greatest Ra values (0.20 µm) were found in specimens polished traditionally by using pumice, whereas the lowest Ra values (0.04 µm) were found in specimens polished mechanically with eggshell powder. The automated polishing system was the most effective polishing method when the Ra values were connected to the level of smoothness.
