“…Table 3 and Figures 1 and 2 show the results of ΔE from the two tested groups. Table 3 shows that the results from the aging treatments and polishing did not differ from each other with the combination of TPH3 and Whiteness HP, while the coloring and bleaching treatments, although not differing, presented significant differences compared with previous treatments when classified using the criteria presented by Seghi et al (16) and adapted by Reis et al (17) for analysis of color change. Analyzing the parameters of color using the L* a* b* coordinates, there was a decrease in brightness of TPH3 when aged and stained, the same increase when cleared and polished ( Fig.…”

“…The total variation in color was calculated using the following formula: The clinical significance for the stability of color was determined using the criteria presented by Seghi et al (16) and adapted by Reis et al (17) for analysis of color change. When the ΔE was higher than 3.7, it was considered an easily visible difference.…”

The objective of this study was to evaluate the effect of two bleaching agents (10% and 35% hydrogen peroxide) on the color stability and surface roughness of two composites, one nanohybrid and one nanoparticle. Specimens were polished, aged, stained, bleached and polished again. The action of the bleaching agents on the composites was analyzed using a profilometer (surface roughness) and a spectrophotometer (color stability). The effect of polishing the composites on the surface roughness and the resumption of the composite color was also evaluated. The results were analyzed statistically by ANOVA and Tukey's test at 5% significance level. The analysis indicated that the nanohybrid composite was more affected by staining. The bleaching agents were not able to promote bleaching of either composite over the evaluation period. Surface polishing returned nanohybrid composite to its original color condition, which did not occur for the nanoparticle composite. Additionally, polishing did not return the surface roughness of either composite to its original value. It may be concluded that polishing surface after bleaching should not be the treatment of choice, as it was not possible to reverse the roughness of the composites to their original values, suggesting that a more extensive and irreversible degradation might have occurred.

Objective:This study evaluated the influence of coffee, tea, cola, and red wine staining on the color of teeth after home bleaching.Materials and Methods:A total of 45 samples were obtained from 45 sound maxillary central incisors. The home bleaching procedure was performed using 10% carbamide peroxide gel applied to the sample surface for a period of 6 h each day, for 14 days. After bleaching, baseline color measurements were taken, and the samples were immersed in four staining solutions (coffee, tea, cola, and red wine) or artificial saliva (n = 9). Following 15 min and 6 h of immersion on the first day and next day, respectively, the samples were washed with distilled water for 10 s. After 15 min, 6 h, 1 week, and 1 month immersions, the color values of each sample were remeasured and the color change values (∆E) were calculated. Color change analysis was performed using a spectrophotometer. The results were analyzed using analysis of variance and Tukey's honestly significant difference test (P <0.05).Results:Of all the staining solutions, the lowest ∆E values were observed with coffee staining versus artificial saliva (control group), for all time intervals evaluated after whitening. Although no statistically differences were observed between the coffee and control group at all the time points evaluated, there were statistically significant differences between the red wine, cola, and tea solutions.Conclusion:Following tooth whitening, patients should avoid drinks that cause tooth staining, particularly red wine, tea and cola.
