Wear resistance and color stability of innovate esthetical Bioflx crowns compared to zirconia pediatric crowns.
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 7 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
backgroundZirconia crowns are the most common aesthetic option for full coverage in pediatric dentistry. Bioflx crowns have been recently introduced, offering a unique combination of aesthetics, flexibility, and durability.
aimThe objective of this study was to evaluate and compare the wear of the crowns and opposing enamel. Additionally, to assess the color stability of Bioflx pediatric crowns following thermodynamic aging compared to zirconia crowns.
methodsForty acrylic resin dies were fabricated based on specific criteria and equally divided into two groups: zirconia crowns and Bioflx crowns. Thermodynamic cycling was conducted to simulate oral conditions over six months. Wear resistance was quantitatively assessed utilizing a Universal Serial Bus (USB) digital microscope with an integrated camera. Color stability was measured using a spectrophotometer before and after thermal aging and following immersion in various solutions (water, milk chocolate, orange juice, and cola). Data were collected, tabulated, and statistically analyzed using the Shapiro-Wilk test and paired sample t-tests. The level of statistical significance was set at a p-value of 0.05.
resultsA statistically significant difference was observed between zirconia and Bioflx crowns regarding volume loss and average roughness height [µm] of the opposing enamel (P = 0.021 and 0.001, respectively). Furthermore, there were significant differences in volume loss (µm
conclusionsZirconia crowns cause more wear on opposing natural teeth than Bioflx crowns. Bioflx crowns show a higher average wear rate than zirconia. There are no significant differences between the two crown's materials in terms of color change after aging and immersion in various solutions.
