This study examined the effect of adhesive tape supplemented with sodium fluoride on the prevention of dental erosion in vitro. Sound bovine tooth samples were selected and divided randomly into the following 4 groups according to the material treatments: group 1, APF gel; group 2, fluoride varnish; and groups 3 and 4, fluoride tape supplemented with 5% NaF in either a methyl cellulose or poly vinyl acetate carrier, respectively. All specimens were submitted to alternate cycles of acid exposure in a cola beverage (pH 4.3) and artificial saliva for $6\;{\times}\;5\;min/day$ over a 5 day period. The micro-hardness was recorded each day and the lesion depth was measured after 5 days. The micro-hardness of the experimental sides of groups 2, 3 and 4 were significantly higher than that of their control sides and the experimental side of group 1 during the experimental period (p<0.05) except on the 5th day. The enamel surfaces of treatment groups 2, 3 and 4 showed significantly higher resistance to mineral loss in terms of the erosion depth (p<0.05) than group 1 and their control sides. There was no statistically significant difference among group 2, 3 and 4, indicating that the fluoride varnish and tapes produce similar results. Fluoride adhesive tapes are effective in reducing the progression of erosion and can be recommended for young patients who are more susceptible to dental erosion.

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.

The purpose of this study is to investigate the residual fluoride concentration of fluoride tape in oral cavity which made by spraying NaF on carboxymethylcellulose base. After 1, 3, 5, 7 hours and 1, 2, 3 days of applicating APF gel(60seconds $taste^{(R)}$, 1.23% APF gel, Group I), Fluoride varnish($CavityShield^{TM}$, 5% NaF, Group II) and Fluoride tape(SCMC-T-5, 5% NaF, Trial product, Group III) in oral cavity of 27 healthy adults in their twenties, the result of fluoride concentration in unstimulated whole saliva which measured by using fluoride sensitive electrode made up to following conclusion. 1. Until 7 hours after application in every group, it showed significantly higher fluoride concentration in saliva than baseline value but at 1, 2, 3 days after application, there were no significant differences between measurements and baseline value(p>0.05). 2. Until 7 hours after application at every time, mean fluoride concentration in saliva was higher in the order of Group II, I and III. 3. 1 hour and 3 hours after application, Group II revealed significantly higher fluoride concentration than Group III(p<0.05), but there were no significant differences between Group Ⅰ and Group III in every time.

This study was designed to evaluate the effectiveness of 5% sodium fluoride-polyvinyl alcohol (NaF-PVA) tape influencing enamel remineralization by analysing enamel surface microhardness (SMH) and variation of ${\Delta}F$ of QLF. After enamel demineralizing of specimen, these 60 specimens with average KHN of microhardness ranging from 50 to 100 and with ${\Delta}F$ of QLF ranging from -15 to -25 were divided into four groups : group 1 (control group), group 2 (NaF-PVA), group 3 (fluoride varnish, FluoroDose$^{(R)}$ varnish), group 4 (Casein phosphopeptide-amorphous calcium phosphate, Tooth mousse plus$^{TM}$). These specimens were treated with materials and then immersed in artificial saliva. We measured remineralization rate each using surface microhardness (SMH) and Quantitative light-induced fluorescence digital (QLF-D). As a result, NaF-PVA tape is better than group 1, 4 and have comparable remineralization effect with group 3 (p < 0.05).

The aim of this in vitro study was to evaluate the effectiveness of experimental 2.26% fluoride-polyvinyl alcohol (F-PVA) tape in inhibition of enamel demineralization using enamel surface microhardness (SMH) analysis and scanning electron microscopy (SEM) examination. Enamel specimens (n=60) randomly assigned to four groups: control group, F-PVA tape group, fluoride varinish (F-varnish) group, casein phosphopeptide-amorphous calcium phosphate (CPP-ACFP) group. After topical application, pH-cycling was processed. Then, SMH was measured and the percentage loss of surface microhardness (%SML) was calculated. For the SEM examination, five sample specimens in each group were treated and the morphologic character was evaluated. After pH-cycling, the SMH values of the enamel specimens of F-PVA tape and F-varnish group were significantly higher than that of CPP-ACFP group, there was no significant difference between F-PVA tape and Fvarnish group. With SEM examination, enamel surfaces in the F-PVA tape group and F-varnish group showed numerous spherical and ovoid crystals formed on the enamel surface were also observed. The density of crystals was higher than that of both control group and CPP-ACFP group. F-PVA tape is effective in inhibition of enamel demineralization. Also, F-PVA tape's inhibition of enamel demineralization is comparable to that of F-vanish and greater than that of CPP-ACFP.
