The purpose of this study was to evaluate the remineralization effects of
fluoride-containing sealant on the artificially created enamel carious lesions. The fluoride
release from the specimen of fluoride-containing sealants, the effect on enamel acid
solubility and micro-hardness from the experimental sealants when applied to carious
enamel surfaces were investigated.
The obtained results were as follows ;
1. Fluoride was a rapid rate of release during the first day, with the amount
diminishing with time. The amount of fluoride released from Fuji Ionomer type ¥² was
higher than that from Teethmate-F and Helioseal-F during the 28 days of immersion
(P<0.05) .
2. The enamel solubility of carious enamel surface was higher than that in the
Teethmate-F, Helioseal-F, and Fuji lonomer type ¥² (P<0.05) , and there was no
significant difference with Teethmate-A and Helioseal (P>0.05) .
3. The microhardness value of carious enamel surface was lowest. However, there was
no significant difference between the other sealants with respect to their effects on
enamel hardness (P>0.05) .
