Summary: The study compared a newer class of flowable bulk-fill resin-based composite (PaBF) with two other materials in terms of flexural strength, microhardness, surface roughness, and color stability. Results showed that PaBF had lower flexural strength and should only be used for small restorations with minimal occlusal stresses.

Summary: This study evaluated the effects of denture cleansers on the surface roughness, hardness, and color stability of 3D printed resins compared to heat-polymerized resin. The results showed that the use of denture cleansers led to an increase in surface roughness and a decrease in hardness over time. The color change was dependent on the type of cleanser used.

Summary: This study aimed to evaluate the effect of different polishing systems on the colour stability of different laminate veneer blocks for chair-side CAD-CAM after UV ageing. The results showed that polishing with the Sof-Lex system significantly improved smoothness and colour stability, while the use of the Zircon Brite system was not successful.

Summary: Thermophysical molding (TPM) treatments can improve the surface properties of thick wood veneer. Increasing temperature and duration of TPM treatments decrease the roughness and increase the wettability of thick veneer. XPS results demonstrate significant chemical changes, with increased carbon content and decreased oxygen content. Increasing temperature leads to a notable increase in the C1/C2 ratio and a decrease in the O/C ratio, which are linearly correlated with the initial wettability.

Summary: This study evaluated the effect of brushing and thermocycling on the surface roughness and color stability of 3D-printed denture base materials. The results showed that polishing, brushing, and thermocycling resulted in acceptable surface roughness for all materials and the color stability was within acceptable thresholds.

Summary: Investigations were conducted on the pore-blocking mechanisms of microbubbles in fractured formations through a series of core flood tests. The results showed that the composition of the microbubble fluid did not affect the size or blockage probability of the bubbles, while the roughness of the fracture surface influenced fluid penetration and increased the possibility of blockage.

Summary: The in vitro study aimed to evaluate the effect of applying a 70% alcohol solution on the physical and mechanical properties of a bisacrylate composite resin, with and without the application of a light-polymerizing glaze, subjected to 0.12% CHX twice a day for 7 days. The results showed that the application of alcohol significantly optimized the properties of the composite resin, but the use of CHX had varying effects on microhardness and roughness when the glaze was applied.

Summary: The study aimed to investigate the shear bond strength of ceramic discs luted to differently etched enamel and dentin surfaces. It found that double etching of dentin with Er:YAG laser can improve adhesion. Laser etching appears to be a viable alternative to acid etching on both enamel and dentin surfaces.

Summary: The purpose of this study was to investigate the effect of different surface treatments on the surface roughness and stainability of interim prostheses produced with 3-dimensional printing technology. The study found that all tested materials had a surface roughness higher than the plaque accumulation threshold, and the application of a surface sealant agent significantly decreased the staining of the materials.
