About this study

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.

Read the 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.

What participants receive

    (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.

What is being measured

The primary outcome is the main question the study is designed to answer.

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

    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).

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

  2. Change from Baseline in plaque index at 1 month after TBI (2nd study-schoolchildren)

    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).

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

  3. Change from Baseline in plaque index at 1 month after TBI (3rd study-adults and children)

    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).

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

Questions about this trial

What is this clinical trial studying?

A study testing The smart toothbrush and smart mirror (STM) system (XiuSolution, Gyeonggi-do, Korea) and Conventional toothbrush in people with Toothbrushing, run by Yonsei University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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 study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04627324, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Nov 2020.
