What is being measured

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

  1. Change on visually determination of tooth colour

    Determination of tooth colour using a visual tooth shade guide

    Measured: 2 weeks (before and after treatment)

  2. Change on spectrophotometer determination of tooth colour

    Determination of tooth colour using a spectrophotometer

    Measured: 2 weeks (before and after treatment)

  3. Subjective evaluation of tooth colour change during follow-up

    Determination of tooth colour relapse using visual tooth shade guide (VITA shade guide)

    Measured: 1, 3 and 6 months

  4. Change on quality of life during treatment and follow-up

    Impact on quality of life using an oral quality of life measuring questionnaire, the Oral Health Impact Profile 14 (OHIP-14). The OHIP-14 ranges from 0 to 56 (final sum of all the seven subscales), with higher scores indicating poorer quality of life.

    Measured: 2 weeks (before and after treatment), 1 month, 3 months and 6 months

  5. Objective evaluation of tooth colour change during follow-up

    Determination of tooth colour relapse using a spectrophotometer

    Measured: 1, 3 and 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Dental bleaching with PaintOn Plus VivaStyle, Dental Bleaching impact in quality of life with PaintOn Plus Vivastyle and Dental bleaching with Opalescence GO in people with Tooth Bleaching and Quality of Life, run by Grupo de Investigação em Bioquímica e Biologia Oral at 1 site in Portugal.

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 4 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 17 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Portugal. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Results are not available in the source record.

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

Contact João Silveira, PhD, MSc (+351966168040, joao.silveira@campus.ul.pt), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change on visually determination of tooth colour (time frame: 2 weeks (before and after treatment)). The study lists 5 primary outcomes in all. 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 17 Jul 2018.
