The Effect of Portable AR on Tooth Brushing Skill for Elementary School Students

The Effect of Portable AR on Tooth Brushing Skill for Elementary School Students

The aim of this study An augmented reality (AR) simulation toothbrushing machine was developed to train proper brushing technique for children. The investigators aimed to evaluate the effects of AR brushing machine on knowledge of dental clearing skill, self-efficacy and dental plaque control in elementary schoolchildren in Taiwan.

A quasi-experimental design was conducted; ten intervention schools (AR group) and ten comparison schools were selected from elementary schools. Overall, grade 3-6 students in the AR group (n = 290) and the traditional group (n = 311), respectively. Students in the AR group received a two-time repeated AR-based training for 30 minutes at two-week intervals. Students in the CG received traditional classroom-based teaching. Baseline and follow-ups information was collected using dental plaque examinations and questionnaires. The generalized estimating equations(GEE) were used to evaluate the outcomes between two groups over time.

Inclusion Criteria:

• Primary school students 3 to 6 grades

Exclusion Criteria:

• Schoolchildren with disability certification.
• Schoolchildren with congenital severe oral diseases (eg. cleft lip and palate )
• Disability to operate the AR system
