“…In fact, there is not a total agreement as for the limit of the human eye to discern the differences that are instrumentally calculated, being obvious that a discoloration that is not detectable by the human eye is clinically meaningless. Some authors 9,16,17 reported this limit to be ∆E=2, while other authors reported ∆E=3.3 as the limit [18][19][20][21][22] for clinical acceptability of color differences. This variation is probably connected with the variability in human eye appreciation of color differences and in experimental conditions of comparison between instrumental and visual evaluation of color differences.…”

“…Ytterbium trifluoride, particles that contribute to fluoride release, is a water-soluble component that leaches from composites after immersion in a solution. 2,22 This may have affected the discoloration of TEF, FBF and VDF in this study.…”

“…The superior color matching of VF (48 vol%), SF (66.8 vol%), PF (70 vol%) and FSXT (46 vol%) may be related to their filler content. These composites contain ≥ 70% wt filler; some studies 2,22 have shown that composites with a high filler content exhibit superior color matching. Ytterbium trifluoride, particles that contribute to fluoride release, is a water-soluble component that leaches from composites after immersion in a solution.…”

Six-month color change and water sorption of 9 new-generation flowable composites in 6 staining solutions Abstract: Color match and water sorption are two factors that affect restorative materials. Discoloration is essential in the lifespan of restorations. The aim of this study was to evaluate color change and water sorption of nine flowable composites at multiple time points over 6 months. 60 samples of each composite were divided into two groups (Color Change and Water Sorption/Solubility). Each Color Change group was divided into six subgroups, which were immersed in distilled water (DW), coffee (CF), Coca-Cola (CC), red wine (RW), tea (TE) and orange juice (OJ). The color was measured at the baseline, 1, 2, 3 and 4 weeks, and 3 and 6 months and color change values ( . Vertise Flow showed the highest water sorption (W S = 69.10 ± 7.19). The Pearson test showed statistically significant positive correlations between water sorption and solubility and between water sorption and ∆E; the positive solubility-∆E correlation was not statistically significant. The findings suggest that water sorption is one factor associated with the ability of composites to discolor; however, discoloration is a multifactorial problem.

“…Thus, the use of polyester strip promotes greater surface smoothness in addition to preventing contact of the material with air, and therefore eliminates the layer of unpolymerized resin. On the other hand, according to Dietschi et al 23 and Rueggeberg, Margeson 30 , the area under the polyester strip appears to have a lower degree of polymerization than the rest of the restoration. Theoretically, this could increase restoration susceptibility to staining.…”

“…Th e intake of pigmentation agents present in beverages such as tea, coff ee, soda, juice and wine are also capable of promoting restoration staining 2-8 in materials with a higher rate of water sorption, because they tend to absorb more pigments since water can transport the dye into the material causing more intense staining 23 .…”

ResumoObjetivo: O objetivo deste estudo foi avaliar o efeito do acabamento e polimento na estabilidade de cor da resina nanoparticulada Filtek Z350 XT em função de diferentes meios de imersão. Material e método: Espécimes circulares (10 mm de diâmetro e 2 mm de espessura) foram preparados para cada grupo (n=6) utilizando uma matriz de aço inoxidável. Os grupos experimentais foram divididos de acordo com a presença ou ausência de acabamento e polimento e diferentes meios de imersão (saliva artificial, Suco artificial pronto KAPO  da Coca-Cola  sabores: abacaxi, laranja, morango e uva). Os procedimentos de acabamento e polimento foram realizados com discos de lixa Super-Snap  . Os espécimes permaneceram em saliva artificial por 24 horas (baseline) e foram submetidos à análise da cor usando um espectrofotômetro pelo sistema CIELab. Em seguida, foram imersos nos diferentes meios por 5 minutos, 3 vezes ao dia, com intervalos de 4 horas, durante 60 dias. Os espécimes foram mantidos em saliva artificial a 37±1°C nos intervalos entre as imersões. Após este período foi realizada nova leitura de cor. Os dados foram analisados com os testes de Kruskall-Wallis e Mann-Whitney. O nível de significância foi de 5%. Resultado: Os resultados mostraram que o acabamento/polimento não influenciou significativamente a estabilidade de cor da resina composta (p>0,05). Não houve diferença estatisticamente significativa na estabilidade de cor da resina estudada após a imersão nos diferentes meios (p>0,05). Conclusão: O acabamento e polimento e os meios de imersão não apresentaram influência na estabilidade de cor da resina nanoparticulada Filtek Z350 XT.Descritores: Resinas compostas; cor; polimento dental. AbstractObjective: The purpose of this study was to evaluate the effect of finishing and polishing on color stability of a nanofilled composite resin (Filtek Z350 XT) according to different immersion media. Material and method: Composite disks (10 mm diameter, 2 mm thickness) were prepared for each group (n = 6) using a stainless steel mold. The groups were divided according to the presence or absence of finishing and polishing procedure and immersion media (artificial saliva, artificial juice-KAPO  Coca-Cola  flavors: pineapple, orange, strawberry and grape). The finishing and polishing procedures were performed using Super -Snap  disks. The specimens were stored in artificial saliva for 24 hours (baseline) and were analyzed using a color spectrophotometer by CIELab system. Then, they were immersed in different media for 5 minutes, 3 times a day, every 4 hours during 60 days. They were stored in artificial saliva at 37 ± 1°C during the immersion intervals. After this time, new measure of color was performed. The data were analyzed using Kruskall-Wallis test and Mann-Whitney test. The significance level was 5%. Result: The results showed that the finishing/polishing not significantly influence the color stability of resin composite (p > 0.05). There was no statistically significant difference in the color stability of the studie...
