The purpose of this study was to evaluate the effects of fluoride releasing orthodontic
sealants, light-cured(Group L1 & L2) and self-cured (Group S1 & S2) FluoroBond
, on enamel microhardness under artificial carious solution in vitro 112
extracted human premolar teeth were collected for experiments and divided into seven
groups.
A Tukon microhardness tester equipped with a Knoop diamond indenter was employed
to determine microhardness. Tukon 23 program converted the number of microhardness
into KHN(Knoop hardness number).
The results were as follows : 1. The microhardness of enamel depth of all groups
were the least at the depth of 50§ and that of all groups except L2 group, the greatest
at the depth of 200§, were the greatest at the depth of 300§. And as the enamel depth
of all groups except L2 and S2 group increased, the microhardness value also increased.
2. There was a little preventive effect in enamel decalcification both light-and self-cured
orthodontic sealant groups, but had no statistical significance between the
groups(p>0.05).
3. Light-cured ortodontic sealant groups had a progressive inhibiting effect in enamel
decalcification at the depth of 100§, 150§, and 200§(p<0.05).
4. Self-cured ortodontic sealant groups had a progressive inhibiting effect in enamel
decalcification at the depth of 150§(p<0.05).
5. There was no difference of the anti-enamel demineralization effect between light-and
self-cured orthodontic sealant groups(p>0.05).
