The effects of mechanical and chemical degradation on the surface roughness, gloss, and color stability of bulk-fill resin composites.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 aim of this study was to evaluate the effects of different pH solutions and brushing on the surface roughness, color stability and surface gloss of different bulk-fill resin composites.
methodsTen disc-shaped specimens were prepared from each resin composite (Filtek Bulk-Fill, Estelite Bulk-Fill Flow, Tetric N-Ceram Bulk-Fill, Opus Bulk-Fill, Admira Fusion X-tra, Beautifil Bulk). After measuring the initial surface roughness, color, and gloss values of the prepared specimens, each group were immersed in the following solutions for seven days: hydrochloric acid solution, cola, and coffee. Afterwards, specimens were subjected to simulated tooth brushing and then surface roughness, color, and gloss values were measured again. The data were analyzed using the One-way ANOVA, Tukey HDS test, Kruskal-Wallis test, Dunn's test, Paired samples t-test (p < .05).
resultsAll bulk-fill composites showed a significant increase of roughness after chemical and mechanical challenges, with the lowest values for Filtek Bulk-Fill and Estelite Bulk-Fill Flow, and the highest values for Beautifil Bulk (p < .05). The gloss was influenced by the challenges, with Beautifil Bulk showing the lowest gloss and highest color change value (p < .05).
conclusionsBulk-fill composite resins were influenced by association of challenges, and Beautifil Bulk showed the highest changes for roughness, gloss, and color.
