“…Therefore, several studies have evaluated the color stability of composites subjected to staining solutions. In the most of these studies, the specimens have been immersed in coffee, grape juice, wine, and other beverages uninterruptedly for long periods of time (hours or days) . However, the exposure of composite restorations to beverages in vivo occurs through several cycles of a few seconds each.…”

This study evaluates whether using adhesive systems for modeling a composite affects the color and opacity changes caused by staining solutions followed by a bleaching procedure. The findings suggest that the use of a universal adhesive as modeling liquid can reduce the alterations in optical properties caused by staining solutions, and the application of high-concentrated hydrogen peroxide over the composite reduce the color changes without fully recover the initial color.

“…Em 2016 Manojlovic et al 27 , averiguando o efeito da cor da resina e do fotoiniciador na translucidez e estabilidade de coloração dos compósitos convencionais e de baixo encolhimento, observaram que fotoiniciadores não apresentaram nenhum efeito significativo sobre a cor. Assim, a cor inicial não exibiu alteração relacionada ao tipo de luz usada na fotopolimerização e as resinas microhibridas à base de FIT (monômero de baixa contração) mostraram maior alteração de coloração em todas as soluções corantes quando comparadas as RBCs à base de BisGMA.…”

ResumoO surgimento das resinas compostas, da técnica de condicionamento ácido e dos variados tipos de adesivos provocaram uma revolução na Odontologia, que aperfeiçoou a devolução da função e estética ao dente. Um dos grandes desafios atuais em dentística restauradora é a manutenção da estética das restaurações de resina composta. O objetivo deste estudo foi revisar a literatura sobre a alteração de cor nas resinas compostas, evidenciando o estado atual das pesquisas sobre o tema. Foi realizada uma síntese de estudos in vitro realizado no período de janeiro de 2011 a janeiro de 2016 indexados na base de dados Pubmed. Seguindo os critérios de inclusão, entraram nesta revisão 13 estudos que avaliaram o grau de descoloração de resinas compostas frente à exposição a diferentes líquidos de coloração. Concluiu-se que apesar do rápido desenvolvimento da biotecnologia e nanotecnologia na Odontologia, novas pesquisas precisam ser feitas a fim de encontrar um material restaurador com propriedades mecânicas e estéticas de excelência, superando as limitações dos atuais.

AbstractThe emergence of composite resins, acid etching technique and various types of adhesives caused a revolution in dentistry, who perfected the return of function and aesthetics of the dental organ. One of the main challenges in restorative dentistry is to maintain the aesthetics of composite restorations. The aim of this study was to review the literature on color changes in the composites, showing the current state of research on the subject. In vitro synthesis studies conducted from January 2011 to January 2016 indexed in Pubmed database was performed. Following the inclusion criteria entered in this review 13 studies that assessed the degree of discoloration composite front resins to exposure to different staining liquids. It was concluded that despite the rapid development of biotechnology and nanotechnology in dentistry, further research needs to be done in order to find a restorative material with mechanical and aesthetic properties of excellence, overcoming the limitations of current.

“…5,6 There is no unanimity about the incidence of failures that lead to replacing the composites, however, today the main cause of changing resins, direct or indirect indication, is the change in color. As a result and because of the aesthetic excellence sought by patients, composite manufacturers continuously seek to improve the optical properties of these materials to enable the adequate reproduction of natural teeth characteristics.…”

“…7 The color stability of a composite is not only determined by the material composition, finishing and polishing of the restoration, it can also be affected by exposure time in the oral cavity and by the patient's eating habits. 6 There are three types of co- would have no effect on color stability and surface degradation of different modified composites. Luminosity is the light level and dark object, represented by the L* value (L*=100 for white and L*=0 for black), and a* b* parameters (shaded) represent the red +a * and green is -a*, yellow if +b * and -b* is blue.…”

“…[2][3][4][5] Choosing an esthetic restorative material is largely due to its ability to imitate the color of the dental element. 6 Using it as a model for obtaining the optical characteristics of dentin and enamel is based on the concept of natural stratification, a simple and effective approach to manufacture highly aesthetic direct restorations. However, preparing aesthetically perfect restorations with direct composite resin is still a challenge for clinicians, because of the complexity to reproduce in these materials the optical properties of natural teeth.…”

Objective: The aesthetics of dental materials is extremely important for the success of oral rehabilitation. Thus, in the present study we evaluated the color stability and the surface degradation of three micro hybrid composite resins after accelerated artificial aging process (AAA). Methods: Were prepared 24 specimens (n=8) for each material: Solidex, Artglass and Cesead, dimensions of Ø 15 mm by 2 mm in thickness. The samples were subjected to color analysis, before and after AAA, in a spectrophotometer according to the CIE L*a*b* parameters, and a sample of each material, was selected for morphological evaluation under scanning electron microscopy (SEM). The data were submitted to one-way ANOVA and Tukey test (α=0.05). Results: Artglass showed higher stability regarding the presence of red and yellow (p<0.05) when subjected to the AAA and fewer of these pigments (p<0.05) when compared to the Cesead and Solidex, which showed the highest luminance stability (p<0.05). ΔE Cesead was the most unstable (p<0.05). All resins analyzed by SEM showed superficial degradation when submitted to the AAA, mainly in resin Cesead. Conclusion: All materials analyzed demonstrate color change and surface degradation, Cesead resin showed the worse results.
