In situ fluoride retention and remineralization of incipient carious lesions after the application of different concentrations of fluoride.

Limited information is available on the time-dependent or dosage-dependent cariostatic efficacy of highly concentrated fluoride compounds. This good clinical practice-conforming, double-blind, placebo-controlled, crossover in situ study tested the hypothesis that a 1.0% amine fluoride fluid is superior to a 0.

Remineralisation of carious enamel lesions after application of a CHX/F-mouthrinse compared with sole CHX- and placebo-application.

Purpose: The purpose of this cross-over, double-blind, placebo-controlled, randomised in situ study was to evaluate the remineralisation of demineralised enamel specimens using a CHX/NaF mouthrinse in comparison with a CHX- and a placebo-mouthrinse.

Materials And Methods: Twenty-four volunteers received intraoral appliances with mounted demineralised enamel specimens. They rinsed their mouths twice a day (10 ml for 1 minute) with the respective preparation.
