mHealth App for Oral Hygiene and Cancer Awareness in Older Adults

The goal of this clinical trial is to learn whether a mobile app with educational videos and serious games is more effective than a video-only version of the app to improve knowledge, attitudes, and practices about oral cancer and oral hygiene in older adults. The study also aims to evaluate the usability of the app and the impact of the intervention on performing oral self-examination. The main questions it aims to answer are: 1. \- Does the version of the app with videos and serious games lead to greater improvement in oral cancer knowledge than the video-only version? 2. \- Are there differences in attitudes and self-examination practices between the two groups after using the app? 3. \- How frequently and consistently do participants use the app during the study period, and how much do they interact with the educational videos and serious games? 4. \- Are there differences in outcomes by sex or education level? Participants will: Be adults aged 60 and more receiving care at the Dental Clinic of the University of Chile Be randomly assigned to use one of two versions of the same app: * Group A: Access to educational videos and serious games * Group B: Access to educational videos only Use the app for 4 weeks Answer a questionnaire before starting, after 2 weeks, and after 4 weeks Perform an oral self-examination at week 4, which will be evaluated using a checklist This trial will help determine whether mobile tele-education tools, especially those that include interactive features like serious games, are effective and acceptable ways to improve oral health education in older adults.
