A Pilot Feasibility Study of an Animation-Based App for Oral Health Education in Children With Hearing Impairment

Abstract

Aim: To design and evaluate an animated educational application to improve oral health among children with hearing impairment. Methods: A feasibility pilot pre–post study was conducted over 2 months with 26 children with hearing impairment. The intervention consisted of application-based animations and questionnaires, developed through focus group input. Knowledge changes in children were assessed using a visual questionnaire, while behavioral changes and application satisfaction were evaluated via online questionnaires completed by mothers, both before and after the intervention. Results: Significant improvements were observed in children's overall oral health knowledge and behavior following the intervention (p < 0.05). While individual items were not statistically analyzed, descriptive data indicated positive trends. Children showed increased awareness of healthy food choices, proper brushing and flossing techniques, and the importance of regular dental visits. Mothers reported behavioral changes, including more frequent toothbrushing and flossing, reduced sugary snack consumption, and increased intake of fruits and milk. High satisfaction among mothers reflected strong acceptability and usability of the intervention. Conclusion: This pilot study demonstrates the feasibility and acceptability of using animation-based applications to promote oral health among children with hearing impairments.
