Artificial accelerated aging and red wine staining on color stability in dental composites.
Article in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe resistance of composite resins to discoloration, staining, and aging is essential for preserving both the aesthetic quality and long-term durability of dental restorations.
objectiveThe study aims to evaluate the effects of artificial accelerated aging (AAA) and red wine staining on the color stability of resin composites.
methodsA2 color disc-shaped specimens (10-mm in diameter, 2-mm thick, n = 5) of 3 resin composites: G-aenial Universal Injectable (GC Corp, Japan), G-aenial A’CHORD (GC Corp, Japan), G-aenial Anterior (GC Corp, Japan), were polymerized using a curing light through a Mylar strip and a 1-mm glass slide for 40 s. Specimens were polished using PoGO disk-shaped polishers (PoGo, Dentsply) for 40 s. Each composite group was randomly distributed into two groups according to the artificial accelerated aging (SUNTEST XXL, Atlas Material Testing Technology) or red wine staining (n = 5). A spectrophotometer (X-Rite Ci7600 Series, Xrite) was used for color measurements at baseline and after AAA and red wine staining. CIEDE2000 color differences (ΔE00) were calculated. Generalized Linear Models and Post hoc Modified Bonferroni tests were used for statistical analysis (p < 0.05). In addition, a 50:50% acceptability threshold of ΔE00=1.8 was used in the result interpretation.
resultsA discoloration was observed in all tested composites; however, the rate of color change (∆E00) in all groups, except for G-aenial Universal Injectable applied to AAA, exceeded the acceptable threshold. The immersion of G-aenial Anterior in red wine resulted in the highest levels of discoloration. Statistically significant differences were observed between G-aenial Universal Injectable and G-aenial A’CHORD in AAA, as well as between G-aenial Anterior and G-aenial A’CHORD. In terms of color change, G-aenial A’CHORD in AAA exceeded those of G-aenial Universal Injectable, and G-aenial anterior in red wine surpassed those of G-aenial A’CHORD.
conclusionsColor stability depends on the composite type and the procedures of red wine staining and AAA. Discoloration was observed in all tested composites. The sole composite demonstrating an acceptable color change was G-aenial Universal Injectable in AAA.
