“…This may be because the regression lines of ∆Eab on ∆E00 change from linear to curvilinear shapes when the values increases in color space. Hence in significant test we can reach different conclusion for ∆Eab and ∆E00 [52].…”

Background:The aim the study to compare the effects of pre-operative air-powder polishing and rubber-cup prophylaxis on tooth bleaching. Methods: 23 subjects suffering from discoloration, were enrolled in a randomized controlled split mouth experimental study. Before bleaching, air powder polishing (APP) and rubber-cup polishing (RCP) techniques were applied on either side of the mouth. A 40% hydrogen peroxide bleaching agent applied two 15-minute applications for in-office bleaching. The tooth bleaching effects assessed immediately after and 1 week.Results: There were no significant differences between prophylaxis groups with respect to all color parameters (∆ L, ∆a, ∆b, ∆SGU, ∆Eab, ∆ E00) at immediate period (p>0,05). At 1 week assessment period there were no significant differences between prophylaxis groups with respect to all color parameters (p>0,05) except delta E00 (p<0,05). Conclusions:Two prophylaxis techniques produced similar efficacy in bleaching treatment and the APP technique produced higher levels of color changes.

“…A 3‐way repeated measures ANOVA was used to analyze the RTP dataset, where the CTC was the within‐subject factor and thickness and cement shade were the between‐subjects factors. All ANOVAs followed the technique of determining an optimized response distribution and, for repeated measures, an optimized covariance structure by finding minimized Akaike and Bayesian information criteria 28 . Each ANOVA used the restricted maximum likelihood estimation method and, for repeated measures, the Satterthwaite degrees of freedom method (SAS Proprietary Software 9.3, SAS Institute Inc., Cary, NC, USA).…”

Objective: To investigate the effect of thickness, cement shade, and coffee thermocycling (CTC) on the optical properties of zirconia reinforced lithium silicate (ZLS) paired with different shades of a resin cement.Materials and Methods: Thirty ZLS specimens were prepared in two different thicknesses (0.8 and 1.5 mm) and three different resin cement shades (Tr, A2, and A3) were applied (n = 5). Color determinations were done before and after 5000 CTC by using a noncontact spectroradiometer. Color change due to CTC and relative translucency parameter (RTP) before and after CTC were calculated by using CIEDE2000. Data were analyzed using ANOVA and Bonferroni-corrected t-tests(α = 0.05).Results: Material thickness and resin cement shade (P < 0.001) affected baseline color. Material thickness affected color difference (P = 0.025). Thickness, resin cement shade, and CTC (P ≤ 0.0001) affected RTP. The difference between the color changes of the 0.8-and 1.5-mm specimens combined with A2 shade cement after CTC was significant (P = 0.01). RTPs of all pairs decreased after CTC (P < 0.001).Conclusions: Cement shade and material thickness affected the baseline color. The thickness of ZLS affected the color change after CTC only with A2 resin cement and the color change was less when the ZLS was thicker. CTC reduced the translucency of all pairs. Clinical Significance: Clinicians and patients should be aware of a potential color change after long-term coffee consumption when zirconia reinforced lithium silicate is used particularly for laminate veneers with A2 shade of the tested resin cement.

“…Complex events occurring in the oral cavity throughout time may lead to changes in the color of resin composites within a certain period which affects the long-term success of the restorations [ 10 ]. The degree of discoloration which may be due to internal or external causes [ 11 ] is influenced by many factors such as water absorption, incomplete polymerization, oral hygiene, diet, the surface characteristics of the restoration and finishing and polishing procedures [ 12 , 13 ]. The organic structure and filler particle properties of resin composites also have a direct effect on the surface roughness of the restoration and the tendency to external coloring [ 14 ].…”

Background The structure of bulk-fill resin composites differs from that of their conventional counterparts, but how this difference affects the color stability of the former after staining and bleaching is unclear. Accordingly, this study was aimed at investigating color change in nine bulk-fill resin composites and one nanohybrid resin composite treated with hydrogen peroxide and carbamide peroxide after staining with tea, coffee, and red wine. Methods Eighty specimens were prepared from each resins [Clearfil Majesty Posterior (CMP), SDR flow+ (SDR), FiltekTMBulk-Fill Flowable Restorative (FBF), Reveal HD Bulk (RHD), Beautifil-Bulk Restorative (BBR), Tetric EvoCeram® Bulk Fill (TEC), SonicFill™2 (SF2), everX Posterior™ (eXP), X-tra base (XB), and Venus® Bulk Fill (VBF)]. Following baseline color measurements, the specimens were randomly divided into 4 groups according to immersion solutions and distilled water as the control. At the end of a 30-day test period, color measurements were repeated, and color change values (∆E00) were calculated. Each resin group was then divided into 2 subgroups (with 10 specimens per group) on the basis of bleaching agent (Opalescence Boost 40%, Opalescence PF 16%). Following bleaching application, ∆E00 and changes of whiteness (∆WID1 = WIDbleaching-WIDbaseline, ΔWID2 = WIDbleaching-WIDstaining) values were recorded. Two- and three-way analyses of variance and Tukey’s post hoc test were performed, with a P < 0.05 regarded as indicative of significance. Results After immersion in distilled water, tea, and red wine, the highest ΔE00 values were observed in eXP (P < 0.05). Resin materials immersed in coffee and tea exhibited statistically higher ∆E00 values than those immersed in red wine except for eXP, TEC, and FBF (P < 0.05). For eXP, the highest ∆E00 values were recorded in distilled water. For TEC and FBF, there was no statistically significant difference among the immersion solutions and distilled water (P > 0.05). For all the resins and staining beverages, no statistically significant difference in ∆WID1 and ∆WID2 values were detected between bleaching agents (P > 0.05). All the ΔWID1 values were above the whiteness perceptibility threshold. Conclusion The bulk-fill materials were more resistant to discoloration and bleaching procedures than the conventional resin composites. Coffee and tea caused more staining than distilled water and red wine generally. The type of bleaching procedure had no effect on the whiteness of the tested materials.
