Calcium fluoride uptake by human enamel after use of fluoridated mouthrinses.
The aim of this study was to evaluate, using scanning electron microscopy (SEM), the calcium fluoride uptake by human enamel in situ after topical application using three fluoridated mouthrinses: a neutral pH solution (Fluordent), an acidulated solution (Fluorgard) and a solution associated with chlorhexidine (Duplak). Twenty-four samples from 6 third sound human molars were divided into two groups: 5-min treatment and 10-min treatment. In both the 5-min and 10-min treatment samples, those treated with the chlorhexidine-associated solution showed higher formation of CaF2-like material. In the 10-min treatment group, the samples treated with the neutral solution showed higher formation of CaF2. These results indicated that the products used deposited CaF2 on the enamel surface and may be recommended to aid the prevention and control of dental caries.
