Analysis of corrosion, surface roughness, and ıon release of orthodontic brackets in simulated gastric acid and saliva.
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
This study aims to assess the ion release (Ni, Cr) and surface roughness of metal (M), self-ligating (SL), and ceramic (C) orthodontic brackets after exposure to simulated gastric acid (pH 1.5, pH 3.0) and artificial saliva (pH 7.0). A total of 198 brackets, metal brackets (M) (n = 66) self-ligating (SL) (n = 66), and ceramic brackets (C) (n = 66) were used in this study. Gastric solutions mimicking human gastroesophageal reflux with a pH of 1, 5 or 3 and as a control group pH of 7 (artificial saliva) were used. All specimens were immersed in test solutions for 30 min, 24 h, and 1 month (n = 22 per group). Inductively coupled plasma-mass spectrometry (ICP-MS) measured ion release, while an optical profilometer assessed surface roughness. Data were analyzed using One-way ANOVA and t-tests (p < 0.05). Ni and Cr ion release peaked at 24 h and decreased by 1 month (p < 0.05). SL brackets released the most ions, particularly in acidic conditions (p < 0.05). Surface roughness was highest at 24 h, then decreased (p < 0.001), with M brackets showing the greatest roughness and C brackets the lowest (p < 0.001). M and SL brackets had the highest roughness at pH 1.5, while C brackets peaked at pH 3.0 (p < 0.001). Acidic conditions significantly impact ion release and surface roughness. Ceramic brackets may be advantageous for patients with reflux disease, offering reduced corrosion and surface alterations.
