“…These findings are in accordance with previous studies [16,17,35]. The microhardness correlates with the content of filler particles of the materials [36]. Only VITABLOCS Mark II revealed a substantial and statistically significant decrease in microhardness after both 1 and 3 years, whereas the other materials only exhibited a statistically significant decrease after 3 years.…”

The aim of the study was to evaluate the effects of erosion and abrasion on resin‐matrix ceramic CAD/CAM materials [CERASMART (GC); VITA ENAMIC (VITA Zahnfabrik); Lava Ultimate (3 M)] in comparison to feldspar ceramic (VITABLOCS Mark II, VITA Zahnfabrik) and resin composite materials (ceram.x universal, Dentsply Sirona). Daily brushing and acid exposure were simulated using a brushing apparatus and a solution of 0.5 vol% citric acid. Microhardness, surface roughness, and substance loss were measured at baseline and after simulation of 1 and 3 years of function. All materials showed a decrease in microhardness after 3 years and an increase in surface roughness (Ra) after 1 and 3 years. The Ra increase was statistically significantly lower for the resin‐matrix ceramics than for feldspar ceramic and similar to composite material. After 3 years, only feldspar ceramic showed no significant substance loss. In conclusion, resin‐matrix ceramics demonstrate reduced roughening compared to feldspar ceramics, potentially improving restoration longevity by preventing plaque buildup, but differences in abrasion resistance suggest the need for further material‐specific research. Future research should aim to replicate clinical conditions closely and to transition to in vivo trials.

“…Nanohybrids are dental composites containing nanofillers (<100 nm) and sub-micron particles (≤1 μm), which allow for more durable and esthetic restorations. 3 4 Surface roughness of nanohybrid dental composites is determined by the resin composite composition and polishing procedures. The size of filler particles in resin composites has been reported to have a significant impact on the transmittance and reflectance of the final restoration.…”

Objective The aim of this study was to test the effect of different bleaching protocols on surface roughness, color stability, and translucency parameter of coffee-stained nanohybrid dental composites with different viscosities. Materials and Methods Five nanohybrid dental composites with different viscosities (n = 250)—Neo Spectra LV, Neo Spectra HV, Neo Spectra Flow (Dentsply, Konstanz, Germany), Grandio, and Grandio Flow (Voco, Cuxhaven, Germany)—were used to test surface roughness, color stability, and translucency parameter after bleaching of coffee-stained specimens using either in-office bleaching, home bleaching, or a combination of both. The viscosity of the five types of dental composites was tested using a viscometer. A scanning laser microscope (SLM) was used to examine the surface topography of representative samples from each dental composite after the combined effect of both bleaching agents. Effect of composite type, bleaching protocol, and their interaction was assessed by two-way analysis of variance. For multiple comparisons, Tukey's post hoc test was used with Bonferroni correction. Results Surface roughness of all coffee-stained dental composites increased after bleaching; however, those of Grandio and Grandio Flow increased significantly (p < 0.0001). This was confirmed by SLM images that showed rough surface with protruding fillers after in-office and home bleaching protocol. Results revealed that bleaching, regardless of the protocol, decreased the delta E values of all dental composites; however, it was still higher than the accepted threshold value of 3.7. Neither of the bleaching protocols enhanced translucency parameter of all dental composites. Neo Spectra Flow and Voco Flow had the highest translucency parameter after the three bleaching protocols. Conclusion Bleaching does not improve color stability and translucency of coffee-stained nanohybrid dental composites regardless of the viscosity. Surface roughness of coffee-stained nanohybrid dental composites increases after application of bleaching agents.

Aim: This study was carried out to evaluate the effect of mechanical fatigue and chemical aging protocols on color stability and translucency of two dental resin composite materials. Method: Twenty disc-shaped specimens were prepared from two types of dental resin composite material; nanohybrid (FiltekTm Z250 XT) and nanofilled (FiltekTm Z350 XT). The 20 specimens were further equally divided into two groups according to aging procedure. Mechanically aged and chemically aged nano hybrid groups were designated with Gp 1A and Gp 2A, respectively. While those of nano filled specimens were designated with Gp 1B and Gp 2B for the same aging treatments, respectively. Baseline readings for color and translucency were recorded before any aging treatment using Reflective spectrophotometer. For mechanical fatigue, the specimens were subjected to 6000 cyclic loading at 23.5 N using chewing simulator, while chemical aging was done by storing the specimens in acidic storage media at pH of 3.6 for 8 days. Using Reflective spectrophotometer, the change in color (Δ E) was measured and the color differences on a standard black and white backgrounds were used to calculate the translucency parameter (Δ TP). Results: After mechanical fatigue aging protocol, The change in color (Δ E) of Gp 1B was significantly higher than of Gp 1A, while chemical aging protocol resulted in insignificant difference in Δ E of Gps 2A &2B. Regarding change in translucency (Δ TP), there was a significant increase in translucency after both aging protocols. Translucency of mechanically
