This study was designed to evaluate the effectiveness of NaF-PVA film influencing enamel remineralization by analysing enamel surface microhardness(SMH) and variation of ?F of QLF. The 60 specimens were divided into four groups at random with average KHN of microhardness ranging from 50 to 100 and with ?F of QLF ranging from -15 to -25 : group 1 (control group), group 2 (NaF-PVA), group 3 (FluoroDose® varnish), group 4 (CPP-ACEP, Tooth mousse plusTM) -These divided specimens were treated with materials and then immersed in artificial saliva. Since then, we obtained following results of Recovery percentage of Surface microhardeness (%SML) and Recovery percentage of ?F(%). After the treatment, the recovery percentage of Surface microhardeness (%SML) values and recovery percentage of ΔF(%) of the enamel specimens of NaF-PVA tape and F-varnish group were significantly higher than that of CPP-ACFP group, and there was no significant difference between group 2(NaF-PVA) and group3(F-varnish). NaF-PVA tape is effective in activation of enamel Remineralization. The activation potential of enamel remineralization of NaF-PVA tape is comparable with that of F- varnish and greater than that of CPP-ACFP. With the significant advantages of excellent physical properties, ease of application, and improved safety, NaF-PVA tape can be used not only for professional treatment, but also in a home-use delivery system.
