Comparative analysis of heat impacts on bond strength and failure modes of calcium silicate- and epoxy resin-based sealers.

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
objectivesA hermetic seal is essential for successful root canal therapy. Sealers fill the interface between gutta-percha and dentin, improving adaptation and sealing ability. This study aimed to evaluate the effect of heat on the push-out bond strength and failure modes of calcium silicate- and epoxy resin-based sealers. MATERIALS AND
methodsThirty-two extracted human premolars with single straight canals were prepared and randomly assigned to two sealer groups (AH Plus, NeoSEALER Flo). Each group was further subdivided based on obturation technique: cold lateral condensation (CLC) or warm vertical compaction (WVC). Root slices from the coronal, middle, and apical thirds were subjected to a push-out test. Failure modes were classified as adhesive, cohesive, or mixed under stereomicroscopy. Data were analyzed using three-way ANOVA and multinomial mixed models with significance set at p < 0.05.
resultsNeoSEALER Flo showed significantly higher bond strength than AH Plus across all root levels and techniques (p < 0.001). Heat application during WVC reduced the bond strength of AH Plus but had no effect on NeoSEALER Flo. In both sealers, the apical third exhibited the highest bond strength, followed by the middle and coronal thirds. Failure analysis revealed predominantly cohesive failures for NeoSEALER Flo, while AH Plus showed more adhesive and mixed failures under heat application.
conclusionNeoSEALER Flo provided superior bond strength and stability regardless of obturation technique. Heat negatively influenced AH Plus but not NeoSEALER Flo, supporting the clinical advantages of calcium silicate-based sealers. CLINICAL RELEVANCE: The findings of this in vitro study suggest that calcium silicate-based sealers may provide improved bond strength and stability compared to epoxy resin-based sealers under different obturation techniques. However, further clinical studies are required to confirm these results under in vivo conditions.
