Influence of Bioceramic Clinker particle size, radiopacifier, and liquids on their physicochemical properties.
Article in Brazilian dental journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
This study evaluated the addition of calcium tungstate (CaWO4) as a radiopacifier and the manipulation with distilled water (DW) or liquid with additives (LA) on the physicochemical properties of Clinker (CL; Angelus) with different particle sizes (2 to 30 µm and <2 µm), compared to White MTA and MTA Repair HP. Initial and final setting times (ST) were evaluated according to ISO 6876:2012 and ASTM C266-03 standards. Radiopacity was assessed following ISO guidelines, and solubility was evaluated after immersion in distilled water or phosphate-buffered saline for 7 days. The pH was measured using a digital pH meter in 1, 3, 7, 14, 21, and 28 days. ANOVA and Tukey and unpaired t-tests were performed (α=0.05). CL 2 to 30 µm showed shorter initial ST and higher final ST when manipulated with LA (p<0.05). The addition of CaWO4 increased the CL radiopacity for both particle sizes (p<0.05) but did not influence ST, solubility, and pH (p>0.05). All materials presented alkaline pH (p>0.05), especially in 24 hours and 7 days. Regarding the solubility, all groups exhibited mass gain, while White MTA in distilled water demonstrated mass loss (p<0.05). CL 2 to 30 µm + CaWO4 showed greater mass gain and higher radiopacity when manipulated with LA than DW (p<0.05). CL <2 µm manipulated with LA provides a shorter final ST. Both particle sizes positively influence the alkalization capacity of CL, especially in the initial periods. The addition of calcium tungstate and manipulation using LA showed adequate physicochemical properties for clinical application.
