Abstract

Objective: The objective of this study is to compare the calcified crystallite materials production, which was estimated as calcium fluoride, after fluoride topical application.
Methods: The authors have observed the enamel, dentin and dentino enamel junction by use of the scanning electro microscope, after fluoride topical application according to such method as APF gel Iontophoresis technique and Fluoride vanish, and according to the frequency of the fluoride application as 1, 2 and 4 times through the iontophoresis method.
Results: It revealed the most in amounts of the crystallite materials production (p＜0.05) in fluoride application with iontophoresis method, at the enamel, dentin and dentino enamel junction, but no difference with the fluoride vanish group in statistical (p＞0.05). It revealed no difference in amounts of the crystallite materials production between the frequency of the application as 1 time and 2 times it the enamel but it revealed more production of crystallite materials in more than 2 times than in control group (p＜0.05). It shown that the more amounts of crystallite materials production in all experimental groups at dentin as 1,2 and 4 times topical application, than in control group (p＜0.05), and the more frequent apply, the more produce the crystallite materials.
Conclusion: It was recommended to apply the fluoride with iontophoresis method for more times every year in clinical and was suggested to apply the fluoride vanish coating after fluoride topical application with the iontophoresis method, in order to increase the caries prevention effect.
