Study summary

The objective of the study is to evaluate the safety and efficacy of the home-use device Silk'n toothbrush (ToothWave) for the improvement in dental health through the reduction of plaque, gingivitis, and calculus.

Read the detailed description

This is a single blind, prospective study aimed to evaluate the safety and efficacy of the Silk'n toothbrush in reduction of gingivitis, dental plaque and calculus.

The study includes 84 treatment sessions, twice a day, and 4 clinic visits over a period of 6 weeks.

One treatment group (Silk'n toothbrush - ToothWave) and 1 control group (an ADA approved power toothbrush (PTB)) will participate in the study.

For each patient, assessment data will be collected at baseline, 4 weeks, and at 6 weeks. The average data sets will be calculated for each group.

Treatment is defined as a timed 2 minutes of teeth brushing in a regular man-ner, twice a day (morning and evening). Brushing will be undertaken using the Silk'n toothbrush and standard fluoride toothpaste. The control group will use a regular PTB and standard fluoride toothpaste.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Feb 2019 to primary completion in Apr 2019, 1 month.

Of 53 industry-sponsored interventional studies with no phase under Gingivitis, half reached primary completion within 3 months of starting (the median), counting those still running; a quarter within 1 and three quarters within 5. This study's 1 month is below that.

Counting every sponsor, half of 257 studies reached it within 7 months; a quarter within 3 and three quarters within 15.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 25, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
