An in-vitro study was conducted on tooth enamel collected in removed samples and processed with pH 5 demineralization solution and with the solution of Crest fluoride toothpaste. Fluoride uptake into demineralized enamel was measured. Result confirms the ability of Crest Toothpaste to prevent dental caries

The study was carried out in vitro to determine the changes of fluoride concentration in tooth enamels that were treated with fluoride dentifrices. The analysis of enamels showed that the fluoride from dentifricaes has been delivered into tooth enamels to contribute to the process of remineralisation at the areas of demineralised enamels. So the fluoride dentifrices have efficacy in preventation of dental caries. The difference of fluoride concentration in enamel samples demonstrated that the anticaries efficacy of dentifrices was also different.
