Translucency, color, and hardness of 3D-printed provisional restorations.
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 4 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 in vitro study investigates effects of different thicknesses (1 mm, 2 mm, 3 mm) and post-curing durations (20 and 25 min) on the translucency parameters (TP), color differences, and microhardness (HV) of NextDent 3D-printed provisional restorations. Fifty-four disk specimens (10 mm diameter) in three thicknesses (1 mm, 2 mm, 3 mm) were post-cured for 20-25 min, forming six groups (n = 9 per group). Color measurements were taken against white and black backgrounds to calculate TP and color differences. Microhardness was measured using a Vickers hardness tester (100 g load, 10 s). Data were analyzed with two-way ANOVA and pairwise comparisons were performed with LSD post-hoc tests (significance level: 0.05). Thickness significantly influenced TP, with 1 mm specimens showing the highest values (P < .05). Post-curing duration did not significantly affect TP or HV (P > .05). Vickers hardness was higher in 1 mm specimens than thicker samples (P < .05). No significant interaction was found between thickness and post-curing time. Thickness affects translucency and hardness in 3D-printed restorations, while post-curing times of 20 and 25 min had minimal impact. Clinicians should consider thickness based on esthetic and functional needs. Future studies should explore broader post-curing times and additional material properties.
