Abstract
The purpose of this study was to examine the effect of fluoride iontophoresis on fluoride uptake and retention on the bovine enamel surface.<br> Bovine enamel was treated with fluoride iontophoresis at 50, 100 and 200μA for two or four minutes. Enamel treated with fluoride alone without iontophoresis was used as a control. The treatment regiments were one time only, or once a day for three consecutive days. The treated enamel was soaked in artificial saliva for 30 minutes, 24 hours and 1 week, and in 1M KOH solution for 24 hours.<br> The results were as follows : <br>1. Iontophoresis significantly increased fluoride uptake in the surface enamel compared with the control.<br> 2. Fluoride uptake increased significantly with an increase in electric current.<br> 3. Iontophoresis significantly increased fluoride retention compared with the control.<br> 4. There was no difference in fluoride uptake between the two- and four-minute treatments with iontophoresis. The two-minute treatment with iontophoresis showed significantly higher fluoride uptake than the four-minute treatment of the control.<br> 5. The treatment with or without iontophoresis showed a greater increase in fluoride uptake and retention in the enamel treated once a day for three consecutive days than for treatment only once. The rate of increase in fluoride uptake and retention were greater with iontophoresis than with the control.<br> The results of this study suggest that iontophoresis enhances the activity of fluoride with respect to fluoride uptake and retention in the enamel surface.
