About

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.

Full 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.

Enrollment: 209 patients

Sex: All

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Participants with poor oral conditions need more toothbrush instruction
• Participants were required to have their gingivitis and baseline plaque scores >1.5 (the Turesky Modification of the Quigley-Hein index)

Exclusion criteria

• if they had gross dental caries or orthodontic appliances, or were medically compromised.
