Introduction:
Mobile 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 Methods:
A 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.
Results:
The 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.
Conclusion:
DentalHelp 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.
