This study was performed to compare the anticarious effects of different fluoride agents( NaF, NH4F, TIFt, APF gel, Elmex gel ) on artificial carious lesion. Enamel samples treated with 5 Winds of fluoride agents by pH cycling method were evaluated for fluoride uptake, enamel solubility, and microhardness.
The results were as follows ;
1. Greater fluoride uptakes were obtained in* carious lesion treated with ?APF gel and TiF4 solution than in that treated with other fluoride solutions.
2. TiF4 group was more resistant to acid than other groups, but it was not significantly different with APF gel group. 3. Surface of enamel specimen was hardened by fluoride application and pH cycling. APF gel was more effective on .enhancing surface hardness than control group.
4. APF gel, NH4F, TiF4 solution were effective on fluoride uptake, enamel solubility, and microhardness.
