Abstract
OBJECTIVE: To investigate the effectiveness of an oral health education programme using a mobile app for adults aged 65 years or older. METHODS: Participants aged 65 or older were randomly allocated into non-app use (n = 25), app use (n = 22) and control (n = 26) groups. The non-app use group received lecture-based oral health education using PowerPoint presentations and participated in workbook activities twice a week for five weeks, whereas the app use group underwent oral health education using a smartphone app and workbook activities for five weeks. Before and after the intervention, a questionnaire survey and oral health examination were performed to examine changes in oral health-related indices. RESULTS: The non-app use group showed significant changes, with a 2.1 increase in oral health knowledge score, 0.2 decrease in the O'Leary index and 0.6 decrease in tongue coating. The app use group showed significant changes, with a 3.1 increase in oral health knowledge score, a 2.5 increase in oral health perception, a 0.3 decrease in the O'Leary index and a 1.4 decrease in tongue coating. Repeated-measures ANOVA showed that interaction between time and group was significant only in tongue coating variable. CONCLUSION: The smartphone app developed in this study carries the possibility to convey informative content for oral health education among older adults.
