The Impact of Thermocycling on the Marginal Discrepancy of Zirconia CAD/CAM Generation on Central Incisors: An

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: Zirconia ceramic materials have become a preferred choice for anterior teeth, but their marginal performance under thermocycling has not been sufficiently investigated. Thus, this Materials and methods: A total of 36 zirconia central incisor crowns were fabricated using three different CAD/CAM systems (ZirCAD Prime, Cercon ht ML, Zolid Bion; 12 per group) and cemented onto models made from resin. After aging for 48 hours in artificial saline, the crowns underwent thermocycling for 10,000 cycles. Marginal discrepancies were measured at two points on four sides per specimen under a digital microscope at 40× magnification. Data were analyzed using analysis of variance (ANOVA) and Results: Before thermocycling, the ZirCAD Prime group demonstrated the lowest overall mean and standard deviation (SD) marginal discrepancy values (55.76 ± 16.41 µm), followed by Zolid Bion (60.95 ± 16.64 µm) and Cercon ht ML (62.93 ± 20.79 µm). After thermocycling, the ZirCAD Prime group demonstrated the lowest discrepancy in overall mean and standard deviation (57.18 ± 16.43 µm), followed by Zolid Bion (62.92 ± 16.31 µm) and Cercon ht ML (63.83 ± 20.92 µm). ANOVA revealed no significant difference in the zirconia groups before ( Conclusion: After thermocycling, all types of CAD/CAM zirconia crowns showed an increase in marginal discrepancies, but these differences remained within clinically acceptable limits.
