The purpose of the present study was to analyze quantitatively the amount of fluoride
release and to observe microscopically the pattern of microleakage and resistance of
enamel to demineralization of four different sealant materials in ordeal to provide
clinician with proper guide in using these materials.
Glass monomer, Fluroshield, Teethmate-F and Concise were used as test materials and
evaluations were performed by pH-ion meted, stereomicroscope and polarizing
microscope for analyses of fluoride, microleakage and anticariogenicity respectively.
The results can be summarized as follows :
1. The amount of fluoride release in each sealant group showed general pattern of
decline. Glass lonomer sealant group showed the highest fluoride release among tested
groups with statistically significant difference(p<.05). There were no statistical
significance in difference between other three groups.
2. Glass lonomer group showed the most severe degree of microleakage, whereas
Concise group showed the least. Fluroshield demonstrated slightly less micr oleakage
than Teethmate-F but with no statistoical significance.
3. The least resistance to demineralization was observed microscopically in Concise
group which has no fluoride in it. No significant difference in lesion depth was found
between fluoride contaning sealant groups, with the exception of 8-week Glass lonomer
group.
4. In Glass lonomer group,lesion depth was decreased with time while in Fluroshield
and Teethmate-F group, statistical significance was found only between 1 & 8 weeks.
5. Although the fluoride containing sealant groups were evaluated to have superior
anticariogenic capacity to groups without fluoride, severe microleakage detected in the
present study calls for further efforts to eliminate this important weakness in order fort
these materials to get wider access to clinical dentistry.
