Wear Resistance and Surface Roughness of Hybrid Ceramic Crowns Compared to Lithium Disilicate: An
Article in Journal of pharmacy & bioallied sciences, 2025. 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
Background: The surface roughness and wear resistance of restorative materials significantly impact the long-term success of dental crowns. Hybrid ceramics have recently been introduced as alternatives to lithium disilicate, with claims of enhanced mechanical performance and ease of milling. Materials and Methods: Twenty extracted human premolars were prepared for full-coverage crowns and randomly divided into two groups ( Results: Post-simulation, Group A showed a mean surface roughness of 1.45 ± 0.12 µm, while Group B recorded 1.28 ± 0.15 µm. The mean volumetric wear was 0.036 ± 0.005 mm Conclusion: Hybrid ceramic and lithium disilicate crowns demonstrated comparable wear resistance under simulated masticatory forces. However, hybrid ceramics exhibited slightly higher surface roughness post-simulation, suggesting potential for greater plaque retention in clinical settings.
