Prevention of Enamel Demineralization Using CPP-ACP-NaF Varnish
- Conditions
- Demineralization
- Interventions
- Device: CPP-ACP-NaF varnish
- Registration Number
- NCT04002232
- Lead Sponsor
- University of Colorado, Denver
- Brief 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. 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.
- 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.

Group Intervention Description CPP-ACP-NaF CPP-ACP-NaF varnish Dental varnish that contains calcium phosphoprotein stabilized amorphous calcium phosphate and sodium fluoride (CPP-ACP-NaF) is applied to the teeth with orthodontic brackets on one side of the mouth immediately after the teeth have received the bracket. Placebo CPP-ACP-NaF varnish Dental varnish base that does not contain calcium phosphoprotein stabilized amorphous calcium phosphate and sodium fluoride (CPP-ACP-NaF) is applied to the teeth with orthodontic brackets on one side of the mouth immediately after the teeth have received the bracket.
