Usability and Perceived Usefulness of a Web-Based Clinical Decision Support System for Managing Periapical Radiolucencies in Root-Filled Teeth.
Article in Journal of dental education, 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
introductionMobile health applications offer valuable support for clinical decision-making. However, usability and perceived usefulness influence adoption. The aim of this study was to evaluate the usability and perceived usefulness of the DentalHelp web app, a clinical decision support system (CDSS) for managing periapical radiolucencies associated with root-filled teeth. MATERIALS AND
methodsA cross-sectional study was conducted with 51 third-year dental students. Participants completed predefined clinical tasks using DentalHelp and assessed its usability and perceived usefulness through the System Usability Scale (SUS) and an adapted Technology Acceptance Model questionnaire. Statistical analyses examined correlations between demographic factors and app evaluation scores.
resultsThe mean SUS score was 96/100, indicating excellent usability. Perceived usefulness was rated 4.65/5, with high agreement on its effectiveness in clinical decision-making. DISCUSSION: DentalHelp demonstrated high usability and usefulness, supporting its role as a clinical and educational tool.
conclusionDentalHelp is a highly usable and useful CDSS for managing periapical radiolucencies, with potential applications in both education and practice. Further studies should explore its impact on clinical outcomes and its long-term adoption.
