Summary

The objective of this study was to compare the efficacy of computer-assisted TBI (toothbrushing instruction) using a smart toothbrush and smart mirror (STM system) in plaque control to that of conventional TBI.

Detailed description

The STM system comprises a smart mirror, which is integrated into a computer monitor, and a 3D motion-capture device inside of a modified toothbrush holder. The computer program displays a toothbrushing animation in the mirror. Toothbrush motions detected by sensors embedded inside the holder are captured and sent to the server for analysis. The investigators evaluated the efficacy of TBI with a STM system by analyzing the reductions of the modified Quigley-Hein plaque index in 1. st study - 60 volunteers (adults) - The data for which have been published (reference) 2. nd study - 42 volunteers (schoolchildren) - manuscript prepared 3. rd study - 60 volunteers (adults and children) These participants were separated randomly into two groups: conventional TBI (control group) and STM system TBI (experimental group). The changes in the plaque indexes were recorded immediately, 1 week, 1 month, and 10 months (1st study only) after TBI.

DEVICE	The smart toothbrush and smart mirror (STM) system (XiuSolution, Gyeonggi-do, Korea)	The STM system comprises a smart mirror, which is integrated into a computer monitor, and a 3D motion-capture device inside of a modified toothbrush holder. The computer program displays a toothbrushing animation in the mirror. Toothbrush motions detected by sensors embedded inside the holder are captured and sent to the server for analysis. (used only during the test visits) Participants had to brush their teeth at home (using toothbrushes with a flat-trimmed nylon bristle of identical type and length.) for 3 min thrice daily, after meals, as recommended by the Korean Dental Association.
