“…Results of the current study after 2 weeks revealed there is statistically significant difference in color change (∆E) with different oral media but was clinically acceptable and this may be related to the short period of immersion of the samples in all media in which surface roughness doesn't increase to the level that affect deposition of coloring agent that alter the color stability 11. Furthermore, the results of the current study was in accordance with those of Bitencourt et al [24] who found that artificial saliva showed the statistically significantly lowest mean ΔE ≤ 2 and this may be due to that saliva does not contain colorant particles. As regard to the effect of carbonated orange juice on the results of color change, although the carbonated orange juice which reported the lowest PH value (2.9) and provided the highest roughness values compared with coffee and artificial saliva, carbonated orange juice did not produce the highest color change values compared to other tested groups.…”

“…It could be defined as due to its lack of yellow colorant and high acid rate, carbonated orange juice did not exhibit more color change than coffee group. These results is in agreement with Bitencourt et al [24] and guler et al [5] who found that color change in group of cola was significant higher than the color change in group of artificial saliva, time was found to be a critical factor for color stability of provisional restorative materials. As immersion time increases, color changes became more intense.…”

“…Also, resins can absorb water at a higher rate because of a high diffusion coefficient25.These properties may explain the cause of the color changes observed with the resin based material. But this was not in agreement with Cevik et al [6] , Alghamdi et al [8] and Bitencourt et al [24] who found that artificial saliva showed the statistically significantly lowest mean ΔE ≤ 2 and this may be due to that water does not contain colorant particles. In the present study coffee was found to cause the highest discoloration effect.…”

To evaluate the effect of different oral media (artificial saliva, carbonated orange juice and coffee) on the surface roughness and color stability of 3D printed temporary material. Methodology: twenty one discs samples were designed using additive manufacturing technique (SLA) were divided into 3 groups and stored in artificial saliva, coffee and carbonated orange juice at 37 ℃. Surface roughness was measured before and after immersion using non-contact USB Digital microscope. Color measurements were made before and after immersions using CIE L*a*b*. Data was analyzed by ANOVA followed by Tukey's pair-wise tests. Results: After two, three and twelve weeks of immersion period there was statistically significant difference between the three tested oral media groups regarding the surface roughness. The highest ΔE values were observed in the coffee (3.58, 4.40 and 10.35 ΔE) followed by Carbonated orange juice mean values (3.29, 3.84 and 7.18 ΔE) while the lowest color changes mean values were for A. Saliva immersed group (1.91, 2.29 and 2.98 ΔE) respectively. Conclusions:1. All different oral media (except A.saliva) used in the present study affected the surface roughness and the color stability of Interim discs constructed using 3-D printing technique. 2. Manufacturing of interim crowns using 3-D printing technique could be used for short-term provisional restoration. 3. This study has shown a strong positive correlation between color change and surface roughness of provisional restorative material.

PURPOSE. The aim was to evaluate the effect of four acidic beverages on the roughness (Ra) and color change (ΔE ab) of two brands of artificial teeth and a heat-polymerized acrylic resin (HPAR) for use in a prosthetic base. MATERIALS AND METHODS. All materials were divided into 5 groups, according to the used acidic beverage (artificial saliva-control, red wine, orange juice, coke-based, and lemon juice-based soft drink). The immersion process was divided into two stages: T1-immersion in the acidic solutions for 10 minutes for 14 days; T2-after T1, the samples were immersed in grape juice for 14 days. The Ra of the samples was evaluated in a rugosimeter and the ΔE ab in a spectrophotometer, before and after the immersions. The analysis of variance of one (ΔE ab) and two factors (Ra) and Tukey were performed (α=.05). RESULTS. There was a statistical difference for roughness after immersion (T1) for Trilux and Tritone teeth, regardless of the acid solution. For Trilux teeth, all acid solutions increased Ra (P<.05). For Tritone teeth, only the coke-based soft drink did not statistically change Ra. Grape juice (T2) altered Ra only of artificial teeth (P<.05). The color was changed for all materials, after T1 and T2. CONCLUSION. In general, the acidic solutions changed the Ra and ΔE ab of HPAR and artificial teeth after T1. The grape juice altered the roughness only of the artificial teeth, promoting a clinically acceptable color change in the materials.

“…Regarding bis-acryl resins, studies that evaluated their behavior in staining solutions concluded that pigments may be able to penetrate the material through the gaps formed after the setting reaction, since bis-acryl resins have a more heterogeneous composition, which facilitates staining and consequent absorption of pigments [19][20][21]. However, there are few studies that assess the color stability of this group of resins, including aging by cigarette smoke.…”

Color and surface gloss stability of bis-acryl and resin composite after exposure to cigarette smoke

et al. 2022

View full text Add to dashboard Cite

Objective: To evaluate color and surface gloss stability of bis-acryl resins and resin composites, submitted to artificial staining with cigarette smoke. Material and Methods: Specimens of each material were prepared (n=15). Two resin composites (GrandioSO [RCG], Filtek Supreme [RCZ]) and five bis-acryl resins (Luxatemp Star [BisLUX], Protemp4[BisPRO], Structor3 [BisSTR], Visalys Temp [BisVIS] and Yprov [BisYPR]) were tested. Initial color was assessed using a spectrophotometer and surface gloss with a glossmeter. Samples were submitted to smoke exposure (10 cigarettes under 8 minutes per cycle). After 3 and 6 cycles, color and gloss were reassessed. Final readings were performed after brush prophylaxis. Data were analyzed using two-way repeated ANOVA and Tukey's test (p<0.05). Results: Differences and interaction of factors (p<0.01) were detected for both color and gloss readings. Resin composites were the least affected by aging, with gloss reduction after prophylaxis. Differences were detected among bis-acryl resins, with better results for BisLUX and BisPRO. BisPRO and BisSTR, showed reduction in gloss after 60 cigarettes, while BisYPR gloss decreased at all evaluated periods. Conclusion: Resin composites are less susceptible to changes after smoke exposure, while bis-acryl resins results are brand-dependent. Prophylaxis negatively influenced the surface gloss of most of the tested materials.
