Influence of Final Irrigation on Calcium Silicate-Based Sealer Dentinal Tubular Penetration: A Systematic Review.
Review in Materials (Basel, Switzerland), 2026. 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
The aim of this systematic review was to assess the influence of different final irrigation protocols and activation methods on the dentinal tubular penetration of calcium silicate-based sealers (CSSs). The review followed the PRISMA 2020 guidelines, and the protocol was registered in the Open Science Framework (OSF; DOI: 10.17605/OSF.IO/5HTVN). A PICOS-based research question was formulated, and a comprehensive literature search was conducted in MEDLINE, Scopus, Embase, Web of Science, and SciELO up to October 2025. After study selection, a qualitative synthesis of methodologies and outcomes was performed, and methodological quality was assessed using the QUIN tool. Twenty-one in vitro studies were included, all of which used single-rooted teeth or single roots. The available evidence suggests that final irrigation protocols may influence CSS penetration, although the magnitude and consistency of this effect varied substantially across studies. Sodium hypochlorite (NaOCl) and 17% EDTA were the most frequently investigated irrigants and were generally associated with improved penetration, but no irrigation protocol or activation technique can currently be considered superior. Current research trends include the evaluation of chelating agents, continuous chelation protocols, and irrigant activation systems such as passive ultrasonic irrigation, sonic activation, laser activation, and XP-Endo Finisher. Future studies should standardize irrigation protocols, activation methods, sealer types, obturation techniques, microscopy-based assessment procedures, and penetration outcome measures, while also including larger samples and more anatomically complex root canal systems.
