A Comparative Assessment of Fracture Resistance of Zirconia Crowns Prepared With Different Finish Line Designs - A
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. Cited by 2 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
Introduction: The purpose of this work is to evaluate and contrast many finish line designs on monolithic zirconia crown fracture resistance. Materials and Methods: Four typhodont mandibular first molar teeth (Nissin TM) were acquired. Tooth preparation was performed. Teeth were classified into four categories according to the architecture of their margins. Group A: Flat-ended shoulder; Group B: Round-ended shoulder; Group C: Radial shoulder; Group D: Deep chamfer. Forty monolithic zirconia crowns were fabricated. One load-to---failure examination using a computer-operated universal testing machine assessed the zirconia crowns' fracture strength. Results: The mean Fracture Resistance for Group A was 1254.266 ± 79.626, Group B was 2324.585 ± 113.996, Group C was 1461.733 ± 93.715, and Group D was 2768.063 ± 96.855. The difference in average Fracture Resistance among the four groups was statistically significant at Conclusion: The outcomes of the current study reveal that the group with a deep chamfer finish line had the greatest fracture resistance. The group utilizing a flat-end shoulder finish line exhibited the lowest fracture resistance.
