“…The L* coordinate change was generally a higher value and a lighter shade. Regarding stain removal, these results appeared to contradict Al-Nadedh et al 19 that using a light in the bleaching process increases the effect of bleaching on the composite, and they suggested that light-activated bleaching had a greater whitening effect on stained composites and might be more beneficial in bleaching restorative resins than in bleaching tooth structures. Using CP-based bleaching agents for resin composite stain removal will raise some esthetic concerns, including possible color mismatches between the restored resin composite and the surrounding tooth structure.…”

“…These results are consistent with previous studies that evaluated the effects of carbamide peroxidebased bleaching agents on resin composites stain removal. Al-Nadedh et al 19 reported that bleaching with 10% CP for four hours daily for 2 weeks was superior to both polishing and 38% hydrogen peroxide-based in-office bleaching procedures for stain removal and can effectively remove stains from all tested materials and return them to a clinically acceptable color. Villalta et al 20 studied the effect of different concentrations of CP (16,18 and 35%) on stain removal from resin composites.…”

Spectrophotometric evaluation of color changes of Bleachshade resin-based composites after staining and bleaching.Aim: The aim of this study was to evaluate the color stability of two commercially available bleach-shade resin composites (RC) after exposure to 3 storage solutions and the effect of 3 bleaching agents on the color stability and stain removal from stained RC. Materials and methods:Two bleach-shade RC were evaluated in this study, including a nanofilled RC, Filtek TM Z350 XT (FZ), and a nanohybrid RC, Tetric ® N-Ceram (TC), in the extra-white body (shade) (XWB) and L shades, respectively. Twenty-seven disk-shaped specimens, each measuring 12 mm in diameter and 2 mm in thickness, were prepared for each RC, with a total of 54 specimens. Specimens were randomly allocated into 3 groups of 9 specimens each and immersed in 3 storage solutions (distilled water, tea and coffee) for 7 days period. The 9 specimens in each staining group were further divided into 3 subgroups. Specimens in each subgroup (n = 3) were bleached using one of the bleaching agents (10 and 16% Zoom NiteWhite amorphous calcium phosphate (ACP), and Zoom 2 chairside with light activation) for 5 days period. The specimen colors were measured with spectrophotometer. The measurements were performed on each sample three times at baseline, after staining, and after bleaching. Color was expressed using the commission international de I'Eclairage (CIE) L*a*b* color space. The color differences (∆E) between the three measurements were calculated and the results were statistically analyzed using Two-way and Three-way analysis of variance (ANOVA) and Tukey's posthoc tests. Level of significance was set at p < 0.05. Results: Tetric® N-ceram materials demonstrated significantly less color change than the FZ and the color change, which was greater after storage in coffee compared to tea, was statistically significant. The bleaching agents significantly influence the color changes of composite specimens. All groups showed (∆E) values below 3.3 after bleaching, except for 'Zoom 2 chairside' with light activation groups, which is shown clinically unacceptable lighter shade (ΔE >3.3). Conclusion: Bleach-shade composites showed significant discoloration (ΔE > 3.3) after being immersed into coffee and tea solutions. Nanofilled composites discolored more than nanohybrid composites, and carbamide peroxide-based bleaching agents were effective in reducing the discoloration to a clinically acceptable value (∆E > 3.3). ORIGINAL RESEARCHClinical significance: In this study, after clinically significant discoloration, low concentrations of carbamide peroxide bleaching agents were effective in removing stains and restoring the color of bleach-shade composites to near baseline color.

“…Dentre os tratamentos estéticos, destacam-se as restaurações de resina composta e o clareamento dental, por este se tratar de um procedimento conservador e seguro 2,4 . Já a resina composta, apesar de ser tão procurada, apresenta algumas desvantagens, sendo uma das quais o fato de que, quando exposta a certas substâncias e influências no meio oral, estas fazem com que sofra mudança de cor 5,6 e, consequentemente, ocorre a perda do padrão estético que se desejava.…”

“…Algumas manchas extrínsecas podem ser parcial ou totalmente removidas por meio de escovação dentária com uso de dentifrício, profilaxia realizada pelo cirurgião-dentista ou ainda repolimento das restaurações 12,13 , para evitar a substituição desnecessária. Entretanto, quando alguns destes casos não são bem sucedidos, o clareamento dental é uma abordagem conservadora bastante indicada e utilizada na atualidade 5,14 .…”

“…No Brasil, o consumo de café é um hábito comum dentre a maioria da população e possui uma característica em comum com a Coca-Cola® e o vinho tinto, a de provocar o manchamento dos dentes e também de restaurações de resina composta que o paciente possui, como já verificado em estudos 5,9 . Outras bebidas e substâncias presentes na dieta de pacientes também já foram alvo de estudos para avaliar o potencial de pigmentação, como sucos de frutas e molhos como ketchup e mostarda 15,16 , além de manchamento ocasionado pelo cigarro 17 .…”

Análise da capacidade de remoção de pigmentos da resina composta pelo peróxido de hidrogênio 35% Resultado: Apresentaram alteração de cor (ΔE -média/desvio padrão de L*) o café (15,7 ± 2,0) e o vinho (15,2 ± 4,6), quando comparados à Coca-Cola® (4,8 ± 1,9). O peróxido de hidrogênio removeu a pigmentação das amostras, porém, para nenhum dos corantes, houve retorno à coloração inicial, principalmente no grupo manchado por café (12,9 ± 1,5); este mostrou diferença significativa quando comparado ao controle (1,6 ± 0,6), diferentemente do vinho (3,3 ± 0,6) e da Coca-Cola® (2,1 ± 0,9), que se aproximaram do grupo controle. Conclusão: As soluções corantes pigmentaram a resina composta, principalmente o café. A aplicação do peróxido de hidrogênio 35% foi eficaz na remoção de pigmentos das amostras, porém, em nenhum dos grupos, com diferentes corantes, houve retorno à coloração inicial (p>0,005).Descritores: Resinas compostas; espectrofotometria; peróxido de hidrogênio; pigmentação. AbstractObjective: Evaluate in vitro the ability to removal pigments of composite resin after application of hydrogen peroxide 35%. Material and method: Concocted to-20 resin samples composed Opallis (FGM), A1 color, in circular metal matrix. The samples were divided into 4 groups (n = 5) the following coloring agents: distilled water (control), coffee, red wine and Coca-Cola®. In the staining, the samples were immersed in the solutions for 72 hours, with daily change of beverages. Proceeded to the application of 35% hydrogen peroxide gel (Whiteness HP Blue Calcium, FGM) in 3 sessions, one application of gel per session that remained in the samples for 40 minutes. Color measurements were made initially after staining after application of the peroxide and for 21 days using Vita Easyshade spectrophotometer. The data were submitted to two-way ANOVA and Tukey's test (α = 0.05). Result: Significant color change was observed in specimens after immersion in the solutions, except the control group. Hydrogen peroxide was capable of removing the stains, however the color did not return to the baseline in any of the staining groups, especially for the groups immersed in coffee. Conclusion: Staining solutions can stain the composite resin. The application of 35% hydrogen peroxide can remove partially the staining, minimizing the color change produced by the staining solutions. However, the bleaching gel was not capable of removing all staining, especially for the coffee group.

The effectiveness of four methods for stain removal from direct resin-based composite restorative materials

Abstract: Compositions of resin-based composite resins play an important role in their susceptibility to stain and their amenability to stain removal procedures. Home bleaching showed good results for the three materials, while office bleach was the least effective.
