Evaluation of the color stability of resin composites against new color changes following a whitening procedure using mouthwashes.
Article in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimThe aim of this study is to assess whether coloured resin composites undergo greater colour changes following exposure to a colouring solution after the use of a whitening mouthwash. MATERIALS AND
methodsSixty composite discs (2 × 8 mm) were prepared and divided into three groups (n = 20). Each group was then randomly assigned to one of two different mouthwash groups (n = 10). The samples were then immersed in a coffee solution for 6 days. The samples were immersed in a whitening mouthwash solution for 24 h. The samples were then immersed in the coffee solution again for 6 days. ∆E values were calculated according to the CIEDE2000 color system. For statistical analysis, the Kolmogorov-Smirnov test, one-way ANOVA, and the LSD Post Hoc test were performed. The significance level was taken as P < 0.05.
resultsFor both ΔE
conclusionIn this study, which investigated whether coloured composite resins undergo further colour changes following exposure to a whitening mouthwash, varying degrees of colour change were observed in the composite resin samples. Re-exposure of the composite resins, which had changed colour following the use of a whitening mouthwash, to the colouring solution did not result in further colour change.
