나노기술을 이용해 제작한 불소함유 접착필름의 치아우식증 예방효과

Abstract

The purpose of this in vitro study was to evaluate the effect of fluoride containing adhesive film on prevention of enamel demineralization. Eighty bovine enamel blocks were divided randomly into 4 groups of 25: (1) APF gel applied ; (2) CavityShieldTM applied; (3) 3% fluoride film applied; (4) 5% fluoride film applied; Early caries lesions were produced by placing each specimen into demineralization solution at pH 4.0 for 72 hours. Then lesion of the surface microhardness were measured by the Vicker's hardness test and the lesions depth were measured by polarizing light microscope. The results of the present study are as follows: 1. Difference of microhardness value (M±SD) between control and experimental side was the highest in group II, followed by group IV, III, I but, no significant difference was between group II, III and IV 2. Difference of mean lesion depth (M±SD) between control and experimental side was the highest in group II, followed by group III, IV and I but no significant difference was between group III and IV

The results of present study indicate that the fluoride film application is more effective than APF gel and is similar fluoride varnish application for prevention of dental caries.
