Effects of resveratrol-enriched endodontic sealants on pulp stem cell viability and collagen production.

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
Root canal sealers should provide effective sealing while remaining biocompatible with periapical tissues. Strategies to further improve their biological performance are desirable. Resveratrol, a bioactive polyphenol with antioxidant and regenerative properties, may enhance cellular responses and tissue repair, representing a promising adjunct for endodontic materials.
aimThe aim of this study was to evaluate cell viability and type I collagen expression in undifferentiated mesenchymal stem cell cultures exposed to EndoSequence BC bioceramic or AH Plus resin-based endodontic cements, with or without the addition of resveratrol. MATERIALS AND
methodCement specimens were prepared in standardized molds (5 mm × 2 mm), allowed to set for 48 hours, sterilized, and conditioned in culture medium at a concentration of 0.2 g/mL at 37 °C. Resveratrol was added to the culture media at concentrations of 0.25 μM and 0.5 μM. The mesenchymal cell cultures were exposed to the different experimental conditions for 24, 48 and 72 hours, after which viability was assessed by MTT assay, and type I collagen secretion was quantified using the enzyme-linked immunosorbent assay (ELISA).
resultsEndoSequence BC demonstrated significantly greater cell viability than AH Plus (p<0.05). At 48 hours, AH Plus combined with 0.5 μM resveratrol showed significantly greater cell viability than the cement alone and the 0.25 μM resveratrol group (p<0.05). In addition, supplementation with 0.5 μM resveratrol significantly increased type I collagen secretion for both cements compared to the corresponding groups without resveratrol (p<0.05), indicating a positive effect on extracellular matrix production.
conclusionsThese findings suggest that resveratrol is a promising additive for improving the bioactivity of endodontic cements, enhancing collagen production and potentially contributing to tissue regeneration and bone repair.
