A recently conceived calcium fluoride-containing remineralization system was tested using human teeth in vitro. The influence of several variables (surface pretreatment, demineralization time, and remineralization time) was studied. Appreciable levels of fluoride taken up by pumiced human teeth were found at depths up to 50 micrometers when remineralization was carried out in either the remineralizing solution or saliva. The successful performance of the delivery device in these laboratory studies is encouraging and indicates that the logical evolution of the crude devices studied thus far could lead to clinically practical fluoride delivery devices.

The efficacy of a new remineralization system was determined in vivo by maintaining a low concentration of approximately 1 ppm fluoride for 48 hrs against a demineralized human tooth. Human subjects were selected who wore removable partial dentures containing two or more of the demineralized teeth with film system. The findings indicate levels of fluoride uptake to 500 ppm at 50 micron depths in experimental sites.
