5% 불화나트륨을 함유한 고분자 접착필름의 법랑질 재광화 효과

Abstract

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.
