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~st study - 60 volunteers (adults) - The data for which have been published (reference)~nd study - 42 volunteers (schoolchildren) - manuscript prepared~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.
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.
