Charcoal whitening agents and composite resin: investigating color change and surface roughness.
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
backgroundThis study aimed to investigate the effects of different charcoal-based whitening products on the color stability and surface roughness of resin composite, following coffee-induced staining and subsequent brushing with whitening products.
methodsFifty disc-shaped specimens of Harmonize nanohybrid composite resin were fabricated and divided into five groups (n = 10 per group): Control (untreated), Colgate Total (CT), Colgate Total + Charcoal Solution (CT + CS), Colgate Charcoal (CC), and Charcoal Powder (CP). The specimens were immersed in coffee for five days to simulate staining, followed by brushing with the respective whitening products. Color changes (ΔE
resultsAll experimental groups showed significant color changes after staining (ΔE
conclusionCharcoal-based whitening products significantly affected color stability and surface roughness, with the CP group showing the greatest adverse effects. Regular and charcoal toothpastes had no significant impact on surface roughness, indicating a safer profile.
