Comparative evaluation of color stability in polished and glazed CAD/CAM ceramics subjected to coffee thermal cycling: an in vitro study.
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
BACKGROUND AND
aimsOptimal color stability is crucial for patient satisfaction in prosthetic dentistry. This study assessed the impact of coffee immersion on the color stability and translucency of polished and glazed lithium disilicate, zirconia, and zirconia-reinforced lithium disilicate ceramics. MATERIALS AND
methodsThis in-vitro study evaluated the color stability and translucency of three CAD-CAM ceramics: lithium disilicate (IPS e.max CAD), monolithic zirconia (Incoris ZI), and zirconia-reinforced lithium disilicate (Vita Suprinity). Ninety specimens (30 per ceramic type) were divided into glazing, polishing, and control groups. After thermal cycling in a coffee solution, color changes (ΔE) and translucency parameters (TP) were measured with a spectrophotometer. ANOVA was used to analyze differences between groups. Post-hoc comparisons were conducted using the Tukey test, with a significance threshold of p < 0.05.
resultsThe results showed no significant differences in color changes (ΔE) between the polished, glazed, and control groups after coffee immersion (P = 0.096). Although coffee immersion caused detectable color changes, these were not clinically perceptible (ΔE > 1.01). Translucency (TP) measurements revealed significant differences between the groups (P < 0.001), with monolithic zirconia showing lower translucency compared to the other ceramics.
conclusionThis in-vitro study showed that coffee immersion negatively impacted the color of all tested CAD-CAM ceramics, although the changes remained within clinically acceptable limits. Surface treatments, including polishing and glazing, had no significant effect on the color stability or translucency of the ceramics. Coffee immersion also did not affect translucency.
