The effectiveness of endoactivator, EDDY, passive ultrasonic irrigation, and XP-Endo finisher r in removing filling materials from retreated root canals.
Article in BMC oral health, 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
backgroundsThe aim of this study was to evaluate the efficacy of supplementary techniques, including conventional needle irrigation (CNI), EDDY (ED), EndoActivator (EA), passive ultrasonic irrigation (PUI), and XP-Endo Finisher R (XP-FR), in removing residual filling materials from oval-shaped root canals during non-surgical endodontic retreatment.
methodsSixty human mandibular premolar teeth were initially prepared using an R25 instrument and filled with gutta-percha points and Bioserra sealer. The initial filling material removal was performed with PTUR D1 (30/0.09) and D2 (25/0.08) files, and the root canals were finally shaped with an R40 instrument. The samples were randomly divided into 5 groups (n = 12) according to the irrigation activation techniques. Residual filling materials in the apical, middle, and coronal thirds were examined using a scanning electron microscope. Statistical analyses were performed using Kruskal-Wallis tests, with a significance level set at p < 0.05.
resultsIn the ED and XP-FR groups, residue scores decreased from apical to coronal (p < 0.05). ED, PUI, and XP-FR showed significantly lower residue scores in all root thirds compared to CNI (p < 0.05) and in the middle third compared to EA (p < 0.05). EA showed lower scores only in the coronal third compared to the CNI group (p < 0.05).
conclusionED, PUI, and XP-FR did not show statistically significant differences, all activation techniques demonstrated better efficacy than the EA and CNI.
