Abstract

Based on the strengths of augmented reality (AR), this study aimed to determine the dental plaque removal efficiency of a guided brushing program in children. This randomized, controlled, double-blind crossover clinical trial evaluated the plaque removal rate after regular brushing versus AR-based guided toothbrushing in 20 children aged 5-12 years. Overall, the dental plaque removal efficiency of AR-based brushing was superior to that of regular brushing (p<0.05). When classified in detail, no significant difference was noted in the plaque removal rate between the two brushing methods in the anterior region (p=0.056), whereas a significant difference in the plaque removal rate was observed in the posterior region (p<0.05). Based on these results, the efficacy of dental plaque removal for brushing using an AR-based smartphone application was confirmed; thus, this can be used for oral health education incorporating ICT technology in the future.
