Prevention of Enamel Demineralization Using CPP-ACP-NaF Varnish
A Early Phase 1 study testing CPP-ACP-NaF varnish in people with Demineralization, run by University of Colorado, Denver at 1 site in United States.
Trial summary
Sometimes when people wear braces, the combination of dental plaque and diets high in sugar and acids can lead to white spots on the teeth surrounding the braces. These are commonly found in people with braces depending on their diet and care of their teeth. Read more about this study

About this study
Official title: Prevention of Enamel Demineralization in Fixed Appliance Orthodontic Patients Using CPP-ACP-NaF Varnish Compared to Blank Varnish Base. A Randomized Split Mouth Controlled Clinical Trial
Sometimes when people wear braces, the combination of dental plaque and diets high in sugar and acids can lead to white spots on the teeth surrounding the braces. These are commonly found in people with braces depending on their diet and care of their teeth. The white spots will still be present when the braces are removed. These white spots are the beginning signs of cavities and show that mineral has been lost from the tooth. This study will be testing a new varnish that is painted on the tooth around the braces to prevent these white spots from forming.
This study will enroll patients who wear braces and have planned teeth extractions. A calcium and fluoride releasing varnish will be painted on the teeth planned to be extracted. Braces will then be placed on the teeth. In 3-6 weeks, the extraction will occur and the teeth will be collected for analysis.
Read the detailed description
This is a randomized split mouth double blinded clinical trial. The CPP-ACP-NaF varnish is commercially available and is used for the treatment of tooth hypersensitivity under FDA 510K K102808. The placebo for this study is the same product without the CPP-ACP-NaF component. Patients with planned orthodontic therapy that include tooth extractions will have orthodontic brackets attached to the to-be-extracted teeth. Each patient will have the CPP-ACP-NaF varnish and the varnish base (without CPP-ACP-NaF) applied to teeth immediately after orthodontic brackets have been applied. The specific teeth (left or right) will be randomly determined as to the application of the varnish or placebo. In this experimental design each patient has CPP-ACP-NaF applied to one side and placebo applied to the other side.
When the teeth are extracted they are transferred to the Carey Laboratory for in vitro evaluations.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing CPP-ACP-NaF varnish in people with Demineralization, run by University of Colorado, Denver at 1 site in United States.
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 5 inclusion and 4 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 7 Jun 2021. 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 United States. 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. Some participants in this study may receive a placebo. 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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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?
Demineralization (time frame: Up to 14 days after teeth extractions). The study lists 2 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 NCT04002232, which also lists 5 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 7 Jun 2021.
