Polyvinyl alcohol기반 고분자 불소 함유 테잎의 구강 내 불소 유리 성능 평가

Abstract

The purpose of this study was to investigate the fluoride-releasing capacity of polymer adhesive tape in oral cavity which made by spraying NaF on PVA base. Experimental group were divided into 3 according to applicative method: group 1(60seconds taste® APF gel), group 2 (FluoroDose® varnish) and group 3(NaF-PVA). Three type of topical fluorides were applied to facial surfaces of 12 teeth. The unstimulated whole saliva was collected at baseline, 1, 3, 6, 12, 24, and 48 hours after application. The fluoride concentration in the salivary samples was assessed with a fluoride-sensitive electrode. Fluoride concentration unstimulated whole saliva of each group was significantly higher than baseline value at 1 and 3 hours after applications (p<0.05). In case of group 3, fluoride concentration was significantly higher than baseline value at 6 hours after application(p<0.05). At 6 hours after application, the fluoride concentration of group 3 was significantly higher than that of group 1 and group 2(p<0.05). But there was no statistically significant difference between the fluoride concentration of group 1 and that of group 2(p>0.05).
