The objective of the study was to evaluate the color stability of 8 recently developed resin composites when exposed to various staining agents. Six disc-shaped specimens made out of 8 resin composite materials were immersed in artificial saliva, coffee, coke, tea, orange juice and red wine. The initial color (T0) of the 288 specimens was assessed by a calibrated reflectance spectrophotometer (SpectroShade, MHT) over a black as well as a white background. All specimens were kept in an incubator (INP-500, Memmert GmbH) at 37°C for 4 weeks. Colorant solutions were changed every 7 days to avoid bacteria or yeast contamination. After 4 weeks of storage in the colorants (T1), spectrophotometric measurements were repeated and DE00 was calculated. When analyzed over a white background, the mean DE00 values varied from 1.5 (Venus Diamond) to 52.4 (Miris 2). When analyzed over a black background, the mean DE00 values varied from 0.8 (Venus Diamond) to 40.0 (ELS). Significant differences were detected when comparing values at T0 and T1 (DE00) for both backgrounds (Anova and Fisher's LSD post hoc test). Resin composite materials do behave in a significantly different way (p value \ 0.01) when exposed to various staining solutions.

“…Resin composites are widely used worldwide due to their capacity of easily reproducing tooth like appearance [1][2][3]. Their use allows for a minimal invasive dentistry which imply lower cost if compared to the more invasive prosthetic approach based on ceramic crowns thus it is preferred by the majority of patients.…”

Objectives: To evaluate the colour stability of 3 recently developed resin based materials continuously exposed to various staining agents.Methods: 144 disc-shaped specimens were made of each of the 3 tested composites (Essentia, Brillant, Inspiro). Half of them were of 1mm thickness, the other half 1.2mm thickness. The thicker group was than polished up to 4000 grit and reduced to 1mm thickness, too. All specimens after 24 h dry storage in an incubator (INP-500, Memmert), received an initial colour measurement by means of a calibrated refl ectance spectrophotometer (SpectroShade, MHT, Niederhasli, Switzerland). Specimens were then divided into 6 groups (n=6) and immersed in 5 staining solutions or artifi cial saliva (control). All specimens were kept in an incubator at 37°C for 28 days. Staining solutions (red wine, curry mixed water, curry mixed oil, tea and coffee) were changed every 7th day to avoid bacteria or yeast contamination. After 28 days of storage spectrophotometric measurements were repeated and L*a*b* scores once more recorded to determine the colour (∆E00) changes.Results: All tested materials showed signifi cant color changes after 28 days staining immersion.When considered over a black background ∆E00 of polished samples varied from 1.7 (Brillant/ distilled water) to 24.1 (Brillant/wine).When considered over a white background ∆E00 of polished samples varied from 1.1 (Essentia/ distilled water) to 32.5 (Inspiro/wine).When considered over a black background ∆E00 of unpolished samples varied from 1.1 (Essentia, Inspiro/distilled water) to 25.8 (Essentia/wine).When considered over a white background ∆E00 of unpolished samples varied from 1.4(Inspiro/ distilled water) to 33.1 (Inspiro/wine). Conclusions:Staining of restorative materials seems to be dependent on the composition of the product itself. Unpolished samples demonstrated to be more prone to staining than the polished ones.

“…The development of systems with multiple shades for dentine and enamel enables clinicians to apply the 'natural layering concept', producing direct restorations that closely emulate the optical properties of the original tooth structure. 3 Conventional resin composite has no intrinsic adhesion to enamel and dentine but relies on intermediary agents with a mechanism that is essentially micromechanical. The 'total etch' technique with phosphoric acid followed by the application of a separate primer and adhesive resin This clinical article describes and discusses the use of preheated nanohybrid resin composite for the placement of direct restorations and luting of porcelain laminate veneers.…”
