“…The dye accumulates more easily when the strain increases the activity of atoms on the surface. The filler particles may be separated from the heat-softened resin when the molecular arrangement of the resin matrix is strained 30 . These results are in accordance with those previous studies of Barakah et al, (2014) 31 and Deljoo et al, (2020) 21 , who reported that the least staining susceptibility of nanofilled composite restorations was created by a welladapted Mylar strip with the smoothest surface.…”

Background: Discoloration of resin composite restorations is a common concern in dentistry. It can be influenced by various factors, such as the composition of the composite material, surface roughness, and exposure to staining agents like tea. Polishing systems and dentifrices are commonly used to maintain the esthetic appearance of resin composite restorations and prevent or minimize discoloration. Therefore, the aim of this was to evaluate the effect of different polishing systems and dentifrices on discoloration of resin composite after immersion in tea staining solution followed by mechanical brushing. Methods: 42 Resin composite discs with 3mm thickness and 10mm diameter were prepared. Specimens were divided into three equal main groups, (n=14) according to polishing system used (Mylar strip, Sof-Lex, PoGo). The specimens were fully immersed in equal amounts of Black tea staining solution and incubated at 37ºC for 7-days. Each group was further subdivided in two subgroups according to the type of dentifrice used with mechanical brushing (N=7). Spectrophotometer was used to measure the color change after polishing, after staining and after brushing. The collected data was tabulated and statistically analyzed using two-way ANOVA. Results: Color change between groups was significantly difference after staining. The highest value was found with Sof-lex (2.95±0.18), followed by PoGo (2.75±0.17), while the lowest value was found with Mylar strip (2.41±0.15). Rapid white (5.20±0.45) had significantly higher color change than Colgate (4.83±0.44) (p=0.010). Conclusions: PoGo produced better surface quality in terms of color stability than Sof-Lex, whitening dentifrice was effective on removing Black tea surface stains than nonwhitening.

“…Therefore, the coffee solution was used as a colorant in the present study. The critical coloration period is the first 5 weeks, during which stain penetration can reach up to five microns ( Ozkanoglu & Akin, 2020 ). In this study, the samples were immersed in coffee for 5 days ( Celik & Iscan Yapar, 2021 ).…”

Background The effects of whitening toothpastes containing nanohydroxyapatite on the surfaces of restorative materials are not well known. This study evaluated the changes in surface roughness and color of coffee-stained restorative materials after brushing with nanohydroxyapatite and other whitening toothpastes. Methods Disc-shaped specimens were formed using microhybrid, nanohybrid, and supra-nano-filled composite (n = 30) and stained with a coffee solution. A brushing simulation was applied with toothpastes containing nanohydroxyapatite (Dentiste Plus White), perlite (Signal White System) and hydrogen peroxide (Colgate Optic White) for 7, 15, and 30 days. Color and surface roughness measurements were taken before and after brushing. Color change (∆E00) was calculated using the CIEDE2000 system. Results Supra-nano-filled composite-Dentiste Plus White, supra-nano-filled composite-Colgate Optic White, and nanohybrid composite-Signal White System were the groups with the greatest color change observed on the 7th, 15th, and 30th days, respectively. The smallest color change was seen in the microhybrid composite-Signal White System, microhybrid composite-Dentiste Plus White, and nanohybrid composite-Dentiste Plus White groups on the 7th, 15th, and 30th days, respectively. No significant surface roughness changes were observed in the nanohybrid composite-Dentiste Plus White, supra-nano-filled composite-Colgate Optic White, supra-nano-filled composite-Dentiste Plus White, or supra-nano-filled composite-Signal White System groups. Conclusions Whitening toothpaste containing nanohydroxyapatite provided a high degree of color change in the short term and did not create significant surface roughness in nanohybrid or supra-nano-filled composites.

“…Surface degradation of dental ceramics occurs when they are exposed to aqueous solutions, pH changes (6) , change in temperature (7) and this can lead to undesirable effects on the restoration, including microbial plaque accumulation (8) and color stainability (9) . Coffee is one of the commonly consumed beverages worldwide.…”

Statement of problem: color stability of ceramic restorations upon common beverage consumption assures its esthetics and clinical acceptability. This study was formulated to evaluate the effect of coffee consumption on color stability of different CAD/CAM ceramics used for esthetic restoration fabrication. Materials and methods:A total of 45 discs were constructed of (IPS Emax CAD, Vita Suprinity & Vita Enamic) 10 mm in diameter and 1.5 mm thick. Samples were divided into three groups (15 discs each) according to the tested material then immersed in instant coffee solution for 12 days, at 37° C in dark environment. Ceramic discs of each material were optically connected with drop of distilled water to composite substrate background. The CIE L* a *b color parameters were recorded before immersion, and after immersion in coffee solution using a spectrophotometer. Data were recorded, tabulated, and statistically analyzed Results: A statistical insignificant difference in mean values of (ΔE) was detected between tested ceramics immersed in coffee. Conclusions:The color of the three tested ceramics changed on immersion in coffee; (ΔE) values were above 3.3, which is clinically unacceptable and unaesthetic.Recommendations: Dentists should warn patients about the effects of dietary habits and staining beverages on dental ceramics.
