Effect of vegan toothpastes on surface characteristics of human enamel after erosion-abrasion.
Article in Brazilian dental journal, 2025. 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
The study evaluated the effect of vegan toothpaste on the surface and elementary constitution of enamel submitted to erosion-abrasion. Human enamel blocks (3x3mm) were submitted to in vitro erosion-abrasion cycling (1% citric acid, 4x/day). After the first and last erosive challenge, the blocks were brushed with the toothpaste: conventional fluoride-free (Bitufo), containing SnF2/SnCl2 (Oral-B Gingiva Detox, 1100 ppm F-), vegan fluoride-free (Boni Natural), or vegan with NaF (Colgate Zero, 1100 ppm F-). The control area was covered with tape, and the test area was left exposed. The tape was removed after cycling, and the blocks were evaluated for surface roughness (Ra, n=10), scanning electron microscopy (SEM, n=5), and energy dispersive spectroscopy (EDS, at%, n=5). Data analysis used split ANOVA, Kruskal-Wallis, and Dunn tests (α=0.05). Ra values in the test area were higher (p=0.01) for fluoride-free (0.389±0.09) and vegan fluoride-free (0.383±0.08) toothpastes compared to SnF2/SnCl2 (0.297±0.05) and fluoridated vegan (0.303±0.06) toothpastes. EDS analysis showed higher Na% (p=0.02) in enamel exposed to SnF2 and SnCl2 toothpaste (=0.7%) than vegan fluoride-free toothpaste (=0.5%). SEM images indicated less surface alteration in enamel exposed to SnF2/SnCl2 toothpaste. Vegan toothpaste with fluoride showed better performance in reducing the effects of surface alteration than vegan fluoride-free toothpaste; however, toothpaste containing SnF2/SnCl2 promoted the enamel surface to be less altered.
