• Conditions: Healthy

• Registration Number: NCT05956262
• Lead Sponsor: Kaohsiung Medical University Chung-Ho Memorial Hospital

Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Self-efficacy	Change from Baseline at 4-week after intervention	2 questions , e.g: I feel confident.Response 1 = strongly disagree 2 = Disagree 3 = Normal 4 = agree 5 = strongly agree
Plaque Control Record (PCR)	Change from Baseline at 4-week after intervention	Each tooth is divided into six surfaces, and the PCR record is calculated ( range 0-100% )
Skill of Toothbrushing	Change from Baseline at 4-week after intervention	5 questions , e.g: The toothbrush is pressed against the gums at a 45-degree angle.Response multiple choice
