About this study

The purpose of the study is to evaluate the effect of various oral hygiene regimes on three volatile sulfur compounds.

Read the detailed description

Thirty male monk volunteers who matched with the including criteria were divided randomly into two groups. Both groups were practiced to brush their teeth with scrubbing method for one week. Then, each group were instructed to do different additional protocol regimen- group A have to do mouth washing and tooth brushing and group B have to practice tongue cleaning addition to tooth brushing for three weeks. At the fifth week, both groups were instructed to practice tooth brushing, mouth washing and tongue cleaning. Three different volatile sulfur compounds were measured by oral chroma. Tongue characteristics, oral examination were checked as the outcomes of this study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • chlorine dioxideOther

    First week, subjects were instructed to do regular tooth brushing. After that group A was requested to use chlorine dioxide mouthwash two time per days for three weeks in addition to tooth brushing and then, one week for combination of tooth brushing, tongue cleaning and mouth washing.

What is being measured

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

  1. Three different volatile sulfur compounds

    Investigator measured three different volatile sulfur compounds: hydrogen sulfide, methyl mercaptan, dimethyl sulfide concentrations (ng/10ml) by using Oral chroma.

    Measured: up to 5weeks

Secondary outcomes (4)
  1. Oral Health examination

    As oral examination, investigator examined present teeth, DMF-T (decayed, missing and filled teeth)

    Measured: up to 5weeks

  2. Tongue coating characteristics

    As tongue coating characteristics, investigator examined tongue coating score (by using winkle tongue coating index) at the baseline, one week later, four weeks later and five weeks later.

    Measured: up to 5weeks

  3. Number of teeth with bleeding on probing

    Measured: up to 5weeks

  4. Plaque index score

    Measured: up to 5weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing chlorine dioxide and small toothbrush for tongue cleaning in people with Halitosis, run by Tokyo Medical and Dental 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 3 inclusion and 3 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 23 Feb 2016. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Three different volatile sulfur compounds (time frame: up to 5weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 23 Feb 2016.
