“…This means that storage in water caused a color change in resin-based materials that can be considered clinically significant and noticeable, whilst storage in grape juice induced color alterations for all experimental groups. These results are in agreement with other studies which demonstrated significant changes in color after coloring processes related to storage in pigmented solutions 6,26,29,31 .…”

“…Previous studies have demonstrated that such parameters are enough to evaluate white spot lesions, since these lesions are more opaque and whiter than healthy enamel. Although some studies use CIEDE2000 system (ΔE 00 ) to assess color measurements, the CIE-Lab system is still a reliable system used and has been used in recent studies to evaluate color stability of white spot lesions 7,26 .Based on this CIE-Lab system, it is possible to calculate the ΔE ab and compare it with a visual perception already reported in the literature (color variation is imperceptible when <1, clinically acceptable when ≤3.3 and unacceptable when above 3.3) 22 . In the present study, color coordinates were obtained at several time intervals as described in the materials and methods section.…”

Aim: To evaluate the color stability of bovine enamel with artificial white spot lesions treated with resin infiltration (ICON) or remineralization with fluoride using two storage methods. Methods: Sixty incisors were submitted to artificial white spot lesion induced by demineralization-remineralization (DE-RE) cycling. Initial color was evaluated with CIE-Lab to measure ΔEab. Demineralized teeth were divided according to the treatment of the white spot lesion (n = 20): 1) Remineralization with 2% neutral fluoride gel for 4min (control); 2) ICON application following manufacturer’s recommendations; and 3) ICON with decreased drying time after the application of ethanol. After 24h, color was evaluated and samples were subdivided (n = 10) according to storage: 1) distilled water for 1 month; 2) grape juice for 10min daily. After storage, color was evaluated. L*, a* and b* data were analyzed by one-way ANOVA and ∆Eab data by two-way ANOVA followed by Tukey’s HSD (α = 0.05). Results: L* was affected by juice storage, and decreased when ICON was applied with decreased drying time after the ethanol application. The same behavior occurred with a* (increase with reduced drying time), while b* was not affected. For ∆Eab significant differences were observed between groups (p = 0.0219) and storage methods (p = 0.0007). There was no interaction effect (p = 0.1118). Remineralization with fluoride presented the lowest color changes after storage in water. Conclusion: Treatment of artificial carious lesions with resin infiltration presented greater color changes than fluoride remineralization after storage in both solutions in vitro.

“…Analyzing the results of this study, we can observe that the most affected parameter was L*, indicating low brightness of the samples subjected to exogenous colorants. We have also found in accordance with the results obtained in other studies, that the polishing of materials allows an improvement in color parameters [20, 39,49].…”

“…However, the results of various studies on color changes induced by exogenous colorants on dental surfaces with incipient caries and on the materials used in their treatment are often controversial [31][32][33][34][35]. Researchers have proposed several methods to evaluate the color changes parameters: colorimetry, guides, color keys, devices, clinical comparison or spectrophotometry [20, [36][37][38][39][40]. The spectrophotometer allows the evaluation of the L*, a* and b* parameters, meaning the color of the specimens in all axes.…”

The aim of this study was to evaluate the potential of coloring of two commercial beverages: coffee and wine, and cigarette smoke, on three materials (ICON infiltration resin, MI Varnish Recaldent, and a sealant based on composite resin) currently used in incipient caries therapy. The study group included 75 extracted teeth that were divided into 3 groups corresponding to each material used. The groups were divided into 5 subgroups that corresponded to each colorant (A. red wine, B. coffee, C. cigarette smoke, D. association of the three colorants, E. control group). The coloration degree of the samples was measured both after the moment of coloring (M3) and after polishing (M4). The results showed a significant increase of the coloring degree for the samples subjected to the combined action of the three colorants (M3), for all the three materials used (DE1*: Id = 23.56, IId = 25.87, IIId = 19.87), and in terms of the coloring degree after the polishing procedure (M4), a decrease of the values was observed (DE2*: Id = 17.56, IId = 21.67, IIId = 16.78). In conclusion, both exposure to the two beverages used in the study and cigarette smoke (C) leads to the appearance of color changes, but the most significant changes were obtained by combining the three colorants (D). Also, the polishing procedure leaded to an improvement of the color variation for all three materials.

“…Materials were polymerized into silicon rings (external diameter 9 mm, internal diameter 6 mm, thick 2 mm) to obtain identical specimens. [ 27 ] Cavities of these rings were slightly overfilled with material, covered with Mylar Matrix Strip (Henry Schein, Melville, NY, USA), pressed between two glass plates and polymerized for 40 s on each side using a curing unit (Celalux II, Voco, Cuxhaven, Germany). One light polymerization mode was used for each material standard: 1000 mW/cm 2 for 40 s. The light was placed perpendicular to the specimen surface, at distance of 1.5 mm or less.…”

Esthetic restorative materials and glass ionomer cements: Influence of acidic drink exposure on bacterial adhesion

et al. 2018

Objective:The purpose of this research was to evaluate and compare bacterial adhesion on five esthetic restorative materials, three glass ionomer cements (GIC), and two GIC with coat. All the materials were considered after acidic drink exposure.Materials and Methods:Thirty cylindrical sample of each of the 10 materials were prepared and then divided into three groups: group 1 (baseline), Group 2 (1 day in acidic soft drink), and Group 3 (7 days in acidic soft drink). Bacterial suspension of Streptococcus mutans was cultured and deposited onto each material, and the adhesion was evaluated through the colony-forming units determination. One-way ANOVA and Bonferroni's post hoc tests were applied to estimate significant differences between the esthetic materials.Results:The highest amount of S. mutans was recorded in Group 3 and the lowest in Group 1 (baseline). In general, the GIC showed bacterial adhesion values higher than the ones related to composites both in Group 2 than in Group 3. Acidic soft drinks lead a time-dependent degradation of restorative materials causing an increase of the surface rugosity. In fact, a general increase in S. mutans cells adhesion to treated samples was observed.Conclusions:The use of acidic soft drink resulted in a degradation of the surface layer of the restorative material with consequent increase of bacterial adhesion. The GIC can be considered a more friendly environment for bacterial adhesion. This is true in particular if acid substances have already deteriorated the surface.
