Association between lesion depth and placement technique with failures requiring extraction of preformed metal crowns in primary molars. A retrospective study.

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
purposeThe aim of the present study was to evaluate the factors associated with failure requiring extraction after placement of preformed metal crowns (PMCs) in primary molars. Radiographic caries depth at baseline (initial/moderate and severe) and placement technique (Conventional and Hall technique) and other patient-related variables were analysed.
methodsClinical and radiographic records from children aged 2-10 years who had at least one primary molar treated with PMCs between 2011 and 2019 were evaluated. Chi-square test, Fisher exact tests and logistic regression analysis (α = 5%) were performed to verify the relationship between the primary outcome and categorical variables (caries depth, restorative teachnique, jaw, tooth type and gender).
resultsA total of 244 teeth treated in 165 children were included in the analysis. A total of 18 failures were observed (7.4%), of which 17 were in deep caries lesions and in which 15 had the PMC placed according to the conventional technique. Both caries lesion depth and restorative technique were associated with treatment failure (p < 0.05).
conclusionTaking into account the limitations of this retrospective study, treatment failures requiring extraction occurred more often in deep caries lesions when treated with preformed metal crowns (PMCs) following the conventional technique when compared to the Hall Technique.
