Effect of surface cleaning methods on bond strength between canal sealer-contaminated dentin and composite resin.

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
backgroundSealer residues on dentin can affect bonding to restorative materials. This study aimed to evaluate the effect of different surface cleaning protocols on the cleaning efficiency and microtensile bond strength of composite resin to dentin contaminated with root canal sealer.
methodsA total of 58 teeth were used in the study (36 for µTBS and 22 for SEM-EDX). Dentin surfaces were exposed and contaminated with an epoxy resin-based sealer (AH Plus) or a bioceramic-based sealer (T-endo Bioserra). Four cleaning methods were examined: dry cotton pellet, cotton pellet with 75% ethanol, surfactant-based cleaner (Katana™ Cleaner), and 37.5% orthophosphoric acid. Control samples had no sealer or cleaning method. Dentin surfaces were bonded with universal adhesive (Scotchbond Universal) and restored with resin composite (Filtek™ Z250). Specimens were divided into subgroups to compare bond strength before and after aging. Bond strength testing was performed using the microtensile bond strength (µTBS) testing. Two teeth from each group were used for SEM and EDX to evaluate cleaning efficiency, and zinc/zirconium percentages were measured to indicate the remaining filler.
resultsBioserra contaminated groups exhibited smaller µTBS values than AH Plus contaminated groups. These values were significant in dry cotton pellet/immediate, ethanol/aged, and KatanaTM/ immediate groups (p˂0.05). Artificial aging decreased µTBS in all groups. This effect was significant in Bioserra/ethanol, AH Plus/Katana™, and Bioserra/phosphoric acid groups (p˂0.05). The lowest µTBS was observed in the dry cotton /Bioserra/aged group and the highest in the phosphoric acid/Bioserra/immediate group.
conclusionsDry and ethanol-impregnated cotton pellet methods are ineffective in removing sealers or increasing bond strength. Katana™ Cleaner and phosphoric acid cleaning effectively cleans and improves bond strength for epoxy and bioceramic sealers.
