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

Student in AR group received a two-time repeated AR-based training for 30 minutes at two-week intervals. The AR-based training system (PVIX Oral, EPED) digitized the steps of the toothbrushing technique applying optical tracking technology to enable the participants to obtain immediate scoring after the completion of practice. The scoring depends on the level of removing simulated dental plaque. The AR system was equipped with an optical tracking unit, a 3D training head model, and a wireless toothbrush. The toothbrushing practice time for the upper and lower jaw is 3 minutes, respectively. A tooth-brushing song played while the students implemented.

Students in the traditional group received a two-time repeated 10-minute lesson regarding proper toothbrushing skills in the classroom at two-week intervals. The students were taught by a well-trained dental hygienist using teaching aids (such as dental models, and toothbrushes).
