Abstract

The purpose of this study is to investigate the residual fluoride concentration of polymer adhesive tape in oral cavity which is made by spraying NaF on PVA base and to compare with Fluoride varnish(Cavityshiled^TM). Experimental groups were divided into two according to application methods; Group 1(NaF-PVA tape) and Group 2(Cavityshiled^TM). Topical fluoride was applied to 20 healthy adults aged from 25 to 30. Fluoride concentration in unstimulated whole saliva was measured by fluoride-sensitive electrode for 72 hours. 1. Until 72 hours after application in every group, significantly higher fluoride concentration was shown in saliva than baseline value(p<0.05). 2. At 2, 3 and 4 hours after application, Group 2 revealed significantly higher fluoride concentration than Group 1(p<0.05). 3. At 24, 48 and 72 hours after application, there was no significance(p>0.05). Although the residual fluoride concentration of saliva and the amount of fluoride of NaF-PVA tape are lower than those of Cavityshield^TM, NaF-PVA tape is considered to be more effective since it showed almost the same result as Cavityshield^TM. Therefore, NaF-PVA tape is expected to be a great fluoride application material.
