Antifungal Efficacy of Chlorhexidine Digluconate and Silver Nanoparticles Incorporated into Molloplast-B Silicone Soft Liner Against Candida albicans: An In Vitro Study.
Review in Journal of clinical and experimental dentistry, 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
Background: Denture stomatitis is a common inflammatory condition among complete denture wearers and is primarily associated with Candida albicans colonization on denture base and soft lining materials. Conventional antifungal therapies often provide only temporary benefits due to limited patient compliance and rapid microbial recolonization. Therefore, intrinsic antifungal modification of silicone-based soft liners may represent a more effective preventive strategy. Material and Methods: Standardized Molloplast-B silicone soft liner discs (6 mm × 1 mm; n = 10 per group) were modified with 1%, 2%, or 3% (w/w) chlorhexidine digluconate (CHX) or silver nanoparticles (AgNPs) using a solvent-assisted dissolution technique followed by heat polymerization. Unmodified Molloplast-B, solvent-processed Molloplast-B, pure CHX solution, and AgNP suspension served as control groups. Antifungal activity against Candida albicans ATCC 10231 was evaluated using an agar diffusion assay after 24-hour incubation at 37°C. Inhibition zones were measured by two blinded examiners. Data were analyzed using one-way ANOVA and Tukey's post-hoc test ( = 0.05). Results: All modified groups demonstrated significantly greater antifungal activity compared with the negative and solvent controls (P < 0.001). CHX-modified specimens exhibited significantly larger inhibition zones than AgNP-modified specimens at all tested concentrations (P < 0.001). The highest antifungal activity was observed in the 3% CHX group (22.6 ± 1.8 mm), followed by the 3% AgNP group (16.0 ± 1.1 mm). A clear dose-dependent increase in antifungal efficacy was observed for both antimicrobial agents. Conclusions: Incorporation of 3% chlorhexidine digluconate into Molloplast-B silicone soft liner resulted in superior short-term antifungal efficacy against Candida albicans compared with silver nanoparticles. This intrinsic modification approach may be a promising strategy for reducing fungal colonization and preventing denture stomatitis; however, further long-term and clinical studies are required.
