The Effect of Erosive Media on Color Stability, Gloss, and Surface Roughness of Monolithic CAD/CAM Materials Subjected to Different Polishing Methods.
Article in Scientific reports, 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
To evaluate the effect of an acidic beverage and simulated gastric acid on the color stability, gloss and surface roughness of different monolithic CAD/CAM materials. Feldspathic ceramic (FC-CEREC Blocks), Lithium disilicate ceramic (LDC-UP-CAD), and resin nano-ceramic (RNC-Lava Ultimate) specimens were subjected to 3 different polishing methods (mechanical-M, glaze-G, and mechanical + glaze-MG) (n = 10). After baseline measurements of color, gloss, and surface roughness, three different immersion protocols (artificial saliva, acidic beverage, and simulated gastric acid) were applied, followed by repeated measurements. Color change was calculated by using the ∆E00 formula. The changes in gloss (ΔGU) and surface roughness (ΔRa) were calculated by subtracting the after-immersion values from the baseline measurements. Statistical analysis was performed using analysis of variance, Kruskal-Wallis and, post-hoc Bonferroni tests (α = 0.05). Statistically significant differences were found for ∆E00 and ΔGU values (p < 0.05), whereas differences in ΔRa measurements were insignificant (p > 0.05). The color change in the acidic beverage was higher for mechanically polished RNC, irrespective of the polishing method (p = 0.025) and immersion solution (p = 0.002). The color change in the simulated gastric acid was higher for mechanically polished LDC compared to other polishing methods (p = 0.003). All groups showed higher ΔGU values when subjected to gastric acid than artificial saliva irrespective of the polishing methods (p < 0.05). Glaze application is necessary to maintain the color of monolithic CAD/CAM restorations for patients who consume acidic beverages frequently. Clinicians should be cautious about gloss changes in monolithic restorations for bulimia nervosa patients.
