Accessing Polyphenols Effect on Bond Strength and Dentin Enzymatic Degradation.
Article in Clinical and experimental dental research, 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
introductionPolyphenols have been investigated in dental materials and restorative techniques due to their interactions with metal cations, antioxidant activity, and collagen crosslinking ability, which make them a promise for reinforcing the dental substrate and improving material adhesion. However, more studies are necessary before to support their use in clinical procedures.
objectivesThis study evaluated the effects of quercetin and resveratrol on bond strength and the protection of dentin collagen fibrils against enzymatic degradation. MATERIALS AND
methodsDemineralized human dentin specimens were immersed for 1 min in solutions of quercetin or resveratrol (100, 250, and 500 µg/mL), 2% chlorhexidine (CHX), or 0.9% saline (control). The specimens were then incubated in collagenase for 24 h at 37°C, and changes in dry mass were measured. For microtensile bond strength testing, quercetin, resveratrol, CHX, or distilled water (DW) were applied to phosphoric acid-conditioned dentin, followed by application of Single Bond 2 (3 M/ESPE) adhesive and Z350XT resin (3 M/ESPE). Adhesive strength was measured after 24 h and after 1 year in distilled water. Data were analyzed using the Kruskal-Wallis and Dunn tests or ANOVA followed by Tukey's test (p < 0.05).
resultsQuercetin-treated specimens showed a significant weight increase compared with CHX (p < 0.05). Both quercetin- and resveratrol-treated groups exhibited resistance to collagenase similar to CHX (p > 0.05). After 1 year, only the DW group showed a significant decrease in bond strength (p = 0.001).
conclusionsDentin treatment with quercetin or resveratrol effectively preserved adhesive strength and protected collagen against enzymatic degradation, suggesting their potential as agents to improve the longevity of adhesive restorations.
