Abstract

Objectives: Tooth decay is one of the most common problems amongst students. Despite considerable educational interventions, it is still very prevalent. The aim of this study was to compare the effect of a dental-oral health mobile educational application with the common dental-oral health education amongst elementary school students. Methods: This interventional study was carried out on 158 girl students in the age range of 10-12 years in Mobarakeh City, Iran. The participants were categorized into the intervention and control groups and investigated in the academic year of 2018-2019. The research tool was a researcher-made questionnaire with confirmed validity and reliability. Initially, all students completed the questionnaires. Later, the intervention group members were trained using dental-oral health mobile educational application and control group received the common dental-oral health educations in lectures and demonstrations. Two months after the last intervention, the same questionnaire was completed and data were analysed by SPSS software. Results: Before the intervention, the mean score of behaviour was 13.69 ± 3.89 and 13.93 ± 3.02 (of 21) for the intervention and control groups. At this phase, the difference between the two groups was not significant in the studied dimensions (p > 0.05). After the intervention, mean scores of the intervention group increased significantly with regard to all variables (p < 0.05). Conclusions: Findings of this study confirmed the positive effect of learning through mobile applications on increasing the students' knowledge, attitude and performance regarding dental-oral health education.
