The hypothesis is that casein phosphopeptide stabilized amorphous calcium phosphate fluoride releasing (CPP-ACP-NaF) dental varnish will be more effective at reducing enamel demineralization than the control varnish base that does not contain CPP-ACP-NaF.


Child to Adult


Research participants will be between 10 and 80 years of age who are subjects undergoing orthodontic treatment at the Department of Orthodontics Clinic, School of Dental Medicine, University of Colorado.
