In-Vitro Tooth Cleaning Efficacy and Filament End Rounding of Different Manual Children's Toothbrushes.
Article in Oral health & preventive dentistry, 2024. 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
purposeThis in-vitro study aimed to investigate the cleaning efficacy of 18 different manual children's toothbrushes applying horizontal, vertical, and rotational movements, as well as to evaluate the rounding of their filament ends. MATERIALS AND
methodsModels equipped with artificial teeth (coated with titanium dioxide) were brushed using a brushing machine with clamped manual children's toothbrushes. The machine carried out horizontal, vertical, and rotational movements for 1 min with a constant contact pressure of 100 g. The percentage of the area of titanium dioxide removed from the buccal, mesial, distal and total surfaces of the artificial teeth corresponded to the cleaning efficacy. To assess the filament design, a scanning electron microscope was used to check the morphology of the filaments which was scored with Silverstone and Featherstone scale. SPSS 22 was used for data analysis.
resultsThe rotational and the vertical movements achieved the best cleaning efficacy with all tested toothbrushes. The vast majority of the tested toothbrushes had their poorest cleaning efficacy in the horizontal movement. Only a small part of the children's toothbrushes (3 out of 18) had a correct and acceptable proportion of rounded bristle ends.
conclusionsBased on the present results, it could be concluded that the cleaning efficacy of different manual children's toothbrushes varied considerably. The best cleaning efficacy was almost always observed for rotational and vertical movements.
