Stainability of 3D-printed resins for denture base and artificial teeth.
Article in BMC oral health, 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
backgroundThe 3D-printed resins for denture bases and artificial teeth are susceptible to staining from the colorants. The purpose of the study is to evaluate the color stability of 3D-printed denture base and artificial teeth resins submitted to staining by beverages for the simulated periods of 3, 6 and 12 months.
methodsDiscs (15 × 3 mm) of denture bases resins [Lucitone 550 (n = 50), Cosmos Denture (n = 50) and NextDent Denture 3D+ (n = 50)] and artificial teeth resins [Duralay (n = 50) and Cosmos Temp (n = 50)] were manufactured. A spectrophotometer evaluated color stability after immersion in: instant coffee, cola, tea, red wine and distilled water, simulating periods of 3, 6 and 12 months of consumption. The data (ΔE00) were submitted to Generalized Estimating Equations (GEE) and Bonferroni post-test (α = 0.05). The perceptibility and acceptability thresholds of color change was set at PT/AT: ΔE00 = 1.7/4.1.
resultsThe Cosmos Denture resin showed greater color change after immersion in coffee and red wine for most periods at unacceptable levels, in comparison to Lucitone and NextDent. The ΔE00 values for NextDent and Lucitone resins were similar to each other regardless of the beverage and the period evaluated. For artificial teeth resins, Cosmos Temp predominantly reached unacceptable levels of staining in most cases, showing visible color changing due to exposure to instant coffee and red wine. Duralay and Cosmos Temp exhibited a time-dependent discoloration.
conclusionsIt was concluded that the Cosmos Denture resin presented the greatest changes in color stability in relation to other denture base resins for coffee and red wine. The 3D-printed denture base resin NextDent showed similar behavior of color change in relation to the conventional heat-polymerized denture base resin, irrespective of the beverage and immersion period. The Cosmos Temp artificial teeth resin showed unacceptable color stability compared to Duralay when immersed in coffee and red wine, irrespective of the period.
