Post-processing effects of Aloe vera on biofilm formation and physical properties of 3D-printed dental resins.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 aims to investigate the post-processing effects of Aloe vera gel (AV) on biofilm formation and the physical properties of 3D-printed dental resins. Samples manufactured using Biomed Clear Resin were assigned to an Aloe vera-treated group (Group AV) and a control group (Group C), with a total of 128 disk-shaped specimens (n = 64 per group). Group AV underwent post-polymerization in 100% Aloe vera gel, while Group C was directly polymerized. For color stability evaluation, specimens were immersed in staining solutions and incubated at 37 °C for 30 days. Surface morphology (SEM/EDX), water sorption (WSP), and water solubility (WSL) were evaluated. Biofilm formation was assessed using Streptococcus mutans. Intergroup differences were analyzed using the Kruskal–Wallis test, followed by Mann–Whitney U tests for post hoc comparisons (p < .05). Group AV was demonstrated to mitigate color alteration, particularly in coffee and red wine solutions, and SEM analysis revealed a microtextured surface structure. Aloe vera post-processing reduced water solubility, while no significant effects were observed on water sorption or biofilm formation. The results indicate that AV treatment improved the physicochemical stability of 3D-printed dental resins, although no significant antibacterial effect was observed. Aloe vera post-processing may represent a promising natural approach to enhance the longevity and aesthetic performance of 3D-printed dental appliances; however, further clinical validation is required.
