Evaluation of the antimicrobial efficacy of the nanoshield barrier on potentially contaminated materials used by students in dental clinics: a cross-sectional study.
Article in Frontiers in oral health, 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: Environmental surfaces and devices routinely used in dental clinics are frequently exposed to microbial contamination from aerosols, droplets, and hand contact, posing a potential risk for cross-infection among patients and healthcare personnel. Aim: This study aimed to evaluate the antimicrobial efficacy of the Nano shield barrier (Nanoveu) on mobile phones, keyboards, computer mouse, and case history files commonly used by dental students in a clinical setting. Methodology: Nanoveu (Nanoveu Ltd), based on nano-shield technology, is a copper-based nanoparticle antimicrobial film. A total of 1000 items (250 mobile phones, 250 keyboards, 250 computer mouse, and 250 case history files) were included in the study. Each device type was equally divided into two halves. One-half was covered with Nanoveu (intervention group) and the other half was covered with a conventional plastic barrier (control group). After two weeks of exposure during dental procedures, swab samples were collected using HiCulture transport swabs, cultured on 5% sheep blood agar and Mac-Conkey agar, and incubated aerobically at 37°C for 24 hours. Data were analyzed using the Kruskal-Wallis and Mann-Whitney U tests through IBM-SPSS. Results: Nanoveu reduced TBC by approximately 63% on mobile phones (596.96 vs 218.96), 70% on case history files (455.04 vs 135.52), 70% on keyboards (797.92 vs 240.16), and 68% on computer mouse (630.4 vs 199.28) compared to the conventional plastic barrier. Conclusion: Nanoveu demonstrated significant antimicrobial efficacy against bacterial contamination on commonly used dental clinic surfaces, supporting its application as a protective barrier in clinical practice.
