About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

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.

Treatment and study plan

The smart toothbrush and smart mirror (STM) system (XiuSolution, Gyeonggi-do, Korea)

Device

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.

Conventional Toothbrush

Device

toothbrushes with a flat-trimmed nylon bristle of identical type and length.

Participants had to brush their teeth at home for 3 min thrice daily, after meals, as recommended by the Korean Dental Association.

Primary outcomes

Change from Baseline in plaque index at 10 month after TBI (1st study-adults)

Time frame: Baseline, immediately after TBI (day 0), 1 week, 1 month and 10 month after TBI.

The effects of smart toothbrush and smart mirror (STM) system TBI and conventional TBI on dental plaque in adults were compared in this study.

Plaque examination was scored on the buccal and lingual surface of all teeth. The Turesky Modification of the Quigley-Hein index was scored between 0 (no plaque) and 5 (plaque covering ≥ two-thirds of the tooth crown) The percentages of plaque removal at each surfaces and whole mouth were determined with the formula: percentage plaque reduction = pre-post / pre X100 (pre=prebrushing plaque value; post=postbrushing plaque value).
Change from Baseline in plaque index at 1 month after TBI (2nd study-schoolchildren)

Time frame: Baseline, immediately after TBI (day 0), 1 week, 1 month after TBI.

The effects of smart toothbrush and smart mirror (STM) system TBI and conventional TBI on dental plaque in schoolchildren were compared in this study.

Plaque examination was scored on the buccal and lingual surface of all teeth (if a permanent tooth had not erupted yet, the primary tooth in the corresponding area was tested).

The Turesky Modification of the Quigley-Hein index was scored between 0 (no plaque) and 5 (plaque covering ≥ two-thirds of the tooth crown) The percentages of plaque removal at each surfaces and whole mouth were determined with the formula: percentage plaque reduction = pre-post / pre X100 (pre=prebrushing plaque value; post=postbrushing plaque value).
Change from Baseline in plaque index at 1 month after TBI (3rd study-adults and children)

Time frame: Baseline, immediately after TBI (day 0), 1 week, 1 month after TBI.

The effects of smart toothbrush and smart mirror (STM) system TBI and conventional TBI on dental plaque in adults and children were compared in this study.

Plaque examination was scored on the buccal and lingual surface of all teeth (if a permanent tooth had not erupted yet, the primary tooth in the corresponding area was tested).

The Turesky Modification of the Quigley-Hein index was scored between 0 (no plaque) and 5 (plaque covering ≥ two-thirds of the tooth crown) The percentages of plaque removal at each surfaces and whole mouth were determined with the formula: percentage plaque reduction = pre-post / pre X100 (pre=prebrushing plaque value; post=postbrushing plaque value).
