“…Thus, when the filler particles are harder than the surrounding resin matrix, the simulated toothbrushing abrades the matrix easily, leading to increased surface roughness and gloss. On the other hand, authors have reported that a homogenous mixture of fillers in the material results in a consistent form of abrasion under toothbrushing; thus, the surface maintains its gloss and shows lower surface roughness [26]. In the author's opinion, this is the possible reason for the overall significant influence of roughness and the low influence on gloss due to toothbrush abrasion, as observed in the present study [27].…”

“…The inorganic content was significantly different in all the polymer-infiltrated ceramic, with Vita Enamic greater than Lava Ultimate, and CU having higher inorganic content than Shofu Block HC. Studies have shown controversial outcomes on the correlation of filler content and surface roughness; however, filler size, filler form, and polymeric matrix played an essential role in influencing the surface quality of the polymer-infiltrated ceramics [25,26]. Moreover, the loss of gloss is influenced by silanization of fillers, size, form, and resin matrix.…”

The aim of this study was to compare the surface roughness and gloss of polymer-infiltrated ceramics after simulated in vitro toothbrushing in different storage mediums. Four polymer- infiltrated ceramics were evaluated, Lava ultimate (LU), Vita enamic (EN), Shofu (SH), and Crystal ultra (CU). The control group was a feldspathic ceramic, Vita Mark II (VM). One hundred and twenty specimens (12 × 14 × 2.5 mm) were prepared using a precision saw. For each material (n = 24), the specimens were allocated into two groups, polished and stained. The specimens of each group were stored (for 7 days) in either citric acid (0.2N) or distilled water. Data for surface gloss (ΔE*SCE-SCI) and roughness (Ra) were evaluated before (baseline) and after simulated toothbrushing. For toothbrushing simulation, a toothpaste slurry containing a toothpaste of 100 relative dentin abrasion (RDA) and 0.3 ml distilled water was used for 3650 cycles (7300 strokes) for each specimen. Data were analyzed using t-test and ANOVA. A p-value of ≤ to 0.05 was considered significant. The highest mean value of surface gloss was identified in CU (stained—water) (4.3 (0.47)) (ΔE*) and EN (stained—acid) (4.3 (1.00)) (ΔE*) specimens, whereas the lowest mean value was shown by SH (stained—acid) (2.04 (0.42)) (ΔE*) samples. The highest mean value of surface roughness was observed in SH (0.40 (0.99)) Ra (stained—acid) whereas the lowest in VM (0.13 (0.039)) Ra (polished— water). A significant difference (p < 0.05) was observed in surface roughness and gloss between the materials with simulated toothbrushing, except in VM and LU, respectively. Therefore, it can be concluded that simulated toothbrushing impacts on surface roughness and gloss, irrespective of the storage medium.

“…Nevertheless, ceramics mechanically polished for just 30 s showed no difference between their initial surface conditions ( 25 ). Can et al state that mechanical polishing affects glaze-treated ceramic surfaces ( 34 ). In our study, we applied mechanical surface treatment via a polishing kit, and each procedure was applied for at least 60 s.…”

Purpose: This study aimed to investigate the discoloration of four types of dental porcelain systems (feldspathic, monolithic zirconia, lithium disilicate, and leucite glassceramic) with various surface treatments (glazed and mechanically polished) after undergoing chewing simulation against a natural tooth antagonist. Materials and methods: Disc-shaped porcelain groups (9x3mm) were produced for the following categories: feldspathic glazed (FG), feldspathic mechanically polished (FM), zirconia glazed (ZG), zirconia mechanically polished (ZM), lithium disilicate glazed (ExG), lithium disilicate mechanically polished (ExM), leucite glass-ceramic glazed (EG), and leucite glass-ceramic (EM). In vitro chewing simulation was conducted on all porcelain groups, and a spectrophotometer was used to compare the color changes between their initial states. Results: The ΔE values (discoloration) of all porcelain samples were statistically different (p <0.05), and the ΔE values of the glazed samples were higher than those of the mechanically polished samples. Conclusion: All the glazed samples are more likely to show more color change than the mechanically polished sample groups.

“…PP pastes cause three-body wear by serving a third body between the restoration and polishing instrument. The resin matrix loss between filler particles and the subsequent debonding of filler particles result in an even rougher surface [23]. Accordingly, the surface roughness values of FC, IC, and CC specimens were significantly increased by RP.…”

This study aimed to investigate the effect of various periodontal hygiene procedures on the surface properties of direct and indirect restorative materials. Disc-shaped specimens (10x2 mm) of FC: Flowable Composite, UC: Universal Composite, IC: Indirect Composite, CC: CAD/CAM Composite were fabricated (n=70) and divided randomly into subgroups: 1-Control, 2-US: Ultrasonic scaling, 3-RP: Rubber-cup polishing, 4-AP: Air-polishing, 5-US+RP, 6-US+AP, 7-US+AP+RP. The color, surface roughness, and gloss measurements were performed. Data were analyzed with variance analysis and the correlation coefficient was used to evaluate the relationship between surface properties (p<0.05). The highest and lowest roughness values were obtained in FC after US and CC’s control group, respectively. The surface roughness of FC, IC, and CC was significantly affected by the application of various prophylaxis procedures (p<0.05). AP and US+AP+RP presented the least and most affected surface roughness, respectively. The lowest surface gloss value was in the US and RP subgroups of FC. The process that the least reduced the surface gloss was AP. Material and procedure affected the color stability (p<0.05) except for CC. The highest ΔE values were obtained in US+AP+RP subgroups. Indirect restorative materials showed less roughness and color change as well as higher gloss values after all periodontal prophylaxis procedures. The use of air-polishing has proven to be a reliable periodontal hygiene approach for direct and indirect restorations due to the less deterioration in the surface properties.
