“…Ra and Rz decrease the biomechanical and esthetic value of prosthetic restorations and growing susceptibility to aging [ 18 ]. Plaque retention with surface staining consistently occurs on rough surfaces of dental restorations [ 19 , 20 ] and cause abrasive damage to opposing dentition [ 21 ]; however, it can also be weakened by the presence of surface flaws or/and cracks, which can lead to prosthesis and ceramic material failure [ 7 , 22 ].…”

Background The study aimed to assess effect of smokeless tobacco (ST) immersion with thermocycling (TC) on color of Vita Classical shade-guide, surface roughness (Ra) and roughness depth (Rz), and compressive fracture force (CFF) of hybrid polymer-infiltrated-feldspathic ceramic (Vita Enamic), leucite-Feldspathic glass (Vitablocs ® Mark II), and zirconia-reinforced lithium silicate (Vita Suprinity) CAD/CAM prosthetic ceramic materials. Material/Methods A 48 samples were milled from Vita Enamic, Vita mark II, and Vita Suprinity. VitaPan shade-guide, Ra, and Rz were registered before ST immersion. Then, the same parameters were recorded again after 15 days of ST staining with and without TC. CFFs and fracture modes of samples after 3 months of aging were documented. Results A slight change was observed in VitaPan shade-guide. Ra and Rz of Vita Suprinity (VS) recorded the highest values among ceramic groups at 3 time intervals. Increases in Ra and Rz were observed after immersion and staining with TC. ANOVA and Bonferroni post hoc tests were used. Significant differences among and between groups were noticed only before immersion in ST and TC, with P value ≥0.00. The highest mean value and SD of CFFs (MPa and Newton) were recorded in Vita Suprinity, followed by Vita Enamic (VE) and Vita mark II (VMII). Reparable fracture was higher in VMII and VS. Conclusions ST staining and TC caused color changes in VitaPan shade-guide and increases in Ra and Rz of tested materials, with highest and lowest values recorded in VS and VE. CFFs were marginally equal to clinically accepted values for VS and equal or slightly higher than the half values for VE and VMII groups.

“…All these restorative materials need to meet aesthetic and functional demands for the treatment success. Previous studies evaluating CAD materials exposed to different beverages, such as coffee, tea, and red wine, have demonstrated that materials are all susceptible to staining [ 7 , 8 , 9 , 10 , 11 ]. Moreover, another common cause of extrinsic staining is cigarette smoking [ 12 ].…”

“…Previous studies have provided insight into the relative long-term color stability and stainability of CAD/CAM-available materials exposed to different beverages, post-aging periods, cigarette smoke, and smokeless tobacco [ 7 , 8 , 9 , 10 , 14 , 22 , 23 , 24 ]. However, the color stainability specifically of LD, Zr, and PMMA both polished and glazed state and when exposed to cigarette smoke have not been previously tested.…”

This study aimed to investigate and compare the color stability and stainability of computer-aided design/computer-aided manufacturing (CAD/CAM) restorative materials in their glazed (G) and polished (P) state when exposed to cigarette smoke, as well as after brushing. Three CAD/CAM restorative materials were investigated: lithium disilicate CAD (LD), zirconia (Zr), and Telio PMMA CAD (PMMA), according to their surface finishing and assignment to cigarette smoking exposure or soaking in the saliva (control) group. The color change (∆E) was calculated before and after the intervention performed for all specimens, using the L*a*b values to quantitatively assess the shade differences. Statistical analysis was performed using one-way repeated measures ANOVA and Bonferroni multiple comparison analysis (α = 0.05). The surface finishing did not influence the materials’ stainability. Color change was noted after smoking, LD and Zr-G and Zr-P had a comparable color change (p > 0.05), while PMMA presented lower ∆E values (p < 0.05). After brushing, all specimens had a significant color change that was high for LD-G and LD-P, and Zr-G, compared with Zr-P and PMMA (p < 0.05). In conclusion, the exposure to cigarette smoke showed that LD, Zr, and PMMA are all susceptible to staining, but brushing decreases surface staining.

“…To compensate for inadequacies in mechanical plaque reduction, mouthwashes like Listerine ® Zero™ are widely used in dentistry and are useful for reducing dental plaque accumulation, gingivitis, and halitosis. However, mouthwashes contain alcohol and hydrogen peroxide that reduce the microhardness of ceramic materials and ultimately lead to the softening and alteration of organic components of these materials rendering them more susceptible to erosion and discoloration [18][19][20][21][22][23][24][25][26][27][28].…”

“…Even though these materials can adequately replicate the dental structure, parameters, like surface roughness (Ra) and surface height (Rz), may be impacted by exposure to the hostile environment of the oral cavity [ 21 ]. The color and light reflection are negatively impacted by a rough surface.…”

This study aimed to evaluate the effect of three oral hygiene tools, a regular toothbrush, an electronic toothbrush, and mouthwash, on the color stability of three different computer-aided design (CAD) and computer-aided manufactured (CAM) ceramic blocks. Feldspathic ceramic (Vita Triluxe Forte), hybrid resin ceramic (Vita Enamic), and lithium disilicate glass-ceramic (IPS e.max CAD) were used in this study. A CAD/CAM system and 81 (27 of each material) samples of ceramic blocks were used. All samples were immersed in black coffee for 15 days, and the coffee was changed twice per day. Using a spectrophotometer probe, samples on a grey background were scanned, and physical properties like surface hardness and depth were measured using interferometry and a 3D non-contact surface metrology. After 30 days of application of oral hygiene tools, instruments were used to measure various physical, mechanical, and optical properties. Vita Triluxe had the highest average color variation values (ΔE 00) after 15 and 30 days of immersion in coffee in both regular and electronic toothbrushes. Moreover, IPS e.max CAD had the least ΔE 00 values with no significant differences among the groups. The surface roughness (Ra) of the Vita Enamic ceramic increased when using a regular toothbrush, and the surface height (Rz) for the Vita Enamic ceramic increased when an electronic toothbrush was used. IPS e.max CAD had the greatest modules of elasticity forces, and Vita Triluxe Forte had the lowest when used with a regular toothbrush. The ΔE 00 values of the tested materials were minimally increased or decreased after 30 days of cleaning, and all were clinically acceptable. Ra and Rz were the highest for Vita Enamic in comparison to the other groups. The highest percentage in IPS e.max CAD was associated with a type 1 fracture, whereas type 3 was predominantly observed with Vita Enamic, and type 2 in the Vita Triluxe group without significant differences.
