Study summary

The objective of the study is to evaluate the safety and efficacy of the home-use device ToothWave (Model H7001) for calculus reduction and the prevention of calculus accumulation.

Read the detailed description

This is a parallel group, single-blind, randomized, and controlled prospective study aimed to evaluate the safety and efficacy of the ToothWave in calculus reduction and prevention of calculus accumulation.

Eligible subjects will undergo a dental prophylaxis, and will enter a two-month run-in phase. A Volpe-Manhold Index (V-MI) calculus examination will be per-formed at the end of the run-in phase. A minimum of 90 qualified subjects (completers) who will form at least 9 mm of calculus on the lingual surface of the mandibular anterior teeth and will qualify to continue participation ac-cording to the eligibility criteria and will be randomly assigned to either the ToothWave or the control brush (ADA-accepted powered TB) group. Subjects will be stratified according to calculus levels (which indicates the calculus growth rate). Stratification will also be conducted according to age, gender, and ethnic group. Subjects will brush twice daily, unsupervised, during a three-month test period, returning at Weeks 3, 6 and 12 for safety and V-MI examinations. An additional visit will be conducted at week 9, during which a supervised brushing will be conducted.

The study test phase will include a total of 168 treatment sessions and 5 clinic visits over a period of 12 weeks.

For each subject, assessment data will be collected at baseline, and at 3, 6 and 12 weeks of the test phase. The average data sets will be calculated for each group.

Treatment is defined as a timed 2 minutes of teeth brushing in a regular manner, twice a day (morning and evening). Brushing will be undertaken using the ToothWave and standard fluoride toothpaste. The control group will use a regular powered toothbrush and standard fluoride toothpaste.

Exclusion criteria

Exclusion Criteria

  1. Subjects who had a medical condition requiring antibiotic premedication prior to dental procedures.
  2. Regular users of a chlorhexidine mouthrinse.
  3. Any oral condition or pathosis that could interfere with study compliance and/or examination procedures (e.g., widespread caries, chronic neglect, advanced periodontal dis-ease).
  4. Current or history of oral cavity cancer or oropharyngeal cancer.
  5. Pacemaker or internal defibrillator, or any other active electrical implant anywhere in the body.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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 Jul 2020 to primary completion in Dec 2020, 4 months.

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 4 months is above that.

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

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 Apr 23, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
