Abstract
Objectives: The purpose of this study was to compare the amount and rate of cumulative fluoride re-leased over a period of 4 h from several varnishes marketed in Korea.
Methods: The following six commercial products were studied: cavity shield (CS, 22,600 ppm F), V varnish (VV, 22,600 ppm F), enamel pro varnish (EP, 22,600 ppm F), MI varnish (MI, 22600 ppm F), fluo-rine care (FC, 22600 ppm F), and fluor protector N (FP, 7700 ppm F). Five samples were collected from each varnish. Further, 10 mg of each varnish were applied onto an acrylic surface (diameter, 5 mm) and then immersed in 20 mL of distilled water at 37oC. The fluoride concentration in each sample was then analyzed after 30 min, 1, 2, 3, and 4 h, and after 4 days of exposure.
Results: The cumulative amount of fluoride released by FC (5.64±1.10 ppm) was significantly higher than that released by other products after 30 min. FC (8.55±1.85 ppm) and MI (8.21±0.81 ppm) released a significantly higher cumulative amount of fluoride after 4 h. The cumulative rate of fluoride released by FC (47.80±9.35%) was significantly higher than that of other products after 30 min. FC (72.44±15.68%) and MI (69.54±6.88%) showed a higher cumulative fluoride release rate after 4 h. MI sustainably released fluoride after 4 h and demonstrated a high fluoride release rate of 95.76%.
Conclusions: The cumulative amount and rate of fluoride released by several varnishes were statistically significant at each time point. This data can be used by clinicians prior to selection of dental products.
