Abstract

Objectives : This study was carried out to examine the effect of varnish fluoride and APF gel on the acid resistance and the remineralization of the enamel. Methods : At first, the microhardness changes of enamel surface were measured after demineralizing the fluoride treated tooth surface. Next, the changes were measured after fluoride application to the demineralized enamel surface. Results : 1. Acid resistance was higher in varnish fluoride groups than APF gel groups and the difference was significant(p after fluoride treatment and after drmineralization. The changes of Vickers hardness number(VHN) were . 2) APF gel groups Microhardness of enamel surface showed after fluoride treatment and after demineralization The changes of VHN were . 2. No significant changes were surveyed in both varnish fluoride groups and APF gel groups as for remineralization of enamel(p>0.05). 1) Varnish fluoride groups Microhardness of enamel surface showed after demineralization and after fluoride treatment. The changes of VHN were . 2) APF gel groups Microhardness of enamel surface showed after demineralization and after fluoride treatment. The changes of VHN were . Conclusions : Varnish fluoride showed higher acid resistance than APF gel, however both of them were observed to have no effect on the remineralization of the enamel.
