Fracture strength of preformed zirconia crown and new custom-made zirconia crown for the restoration of deciduous molars: in vitro study.
Article in European archives of paediatric dentistry : official journal of the European Academy of Paediatric Dentistry, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
purposePreformed metal crown (PMC) were considered as the best method of restoring primary molars. In recent years, dentistry has seen the emergence of esthetic full-coverage restorative alternatives that gave better results but their ability to manipulate the size, shape, and fit is very limited. The milled zirconia crown is a new alternative for the restoration of deciduous teeth, but the mechanical properties of these restorations need to be tested.
aimTo assess and compare the force required to fracture on two posterior pedodontics crowns: a prefabricated Zirconia crowns (PZC) (NuSmile Zr Zirconia
methodsThirty freshly extracted deciduous molars were selected and were randomized into two groups: (1) molars prepared to receive the PZC and (2) molars prepared to receive the milled zirconia crowns. All pediatric crowns were cemented with glass ionomer and the samples were placed in the thermocycling machine for thermal aging of 1000 cycles. Mechanical compression forces were applied using the Universal Testing Machine until fracture of the crowns. The force required to fracture were evaluated. Since variable was normally distributed with Kolmogorov-Smirnov test, Student t test was used for statistical comparison.
resultsThis study showed that the mean fracture force was significantly elevated with zirconia crowns made with Zirkid
conclusionConsidering the limitations of the present in vitro study, further in vitro and in vivo studies are required to support the use of Zirkid
