Color Stability of Extrinsically Colored Monolithic Zirconia: A Narrative Review.
Review in Cureus, 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
Monolithic zirconia has become a widely used restorative material in prosthodontics due to its high mechanical strength, biocompatibility, and improved esthetic properties. To further enhance esthetic outcomes, extrinsic staining is commonly applied to monolithic zirconia restorations, allowing individualized shade characterization and surface effects. However, because these coloring agents are in a superficial layer, concerns remain regarding their long-term durability and color stability under different oral conditions. This narrative review aimed to evaluate the long-term color stability and optical durability of monolithic zirconia crowns treated with extrinsic stains, under simulated aging conditions. An electronic search was conducted across PubMed, ScienceDirect, and Wiley Online Library databases between 2016 and February 2026, investigating the effects of mechanical, chemical, thermal, and hydrothermal aging on extrinsically stained monolithic zirconia. A total of 1354 articles were initially identified. After removing duplicates and screening titles and abstracts, nine articles met all inclusion criteria and were included in the final analysis. These studies primarily evaluated color variation (ΔE, ΔE
