Abstract
|
|
|
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 order to
provide
clinician with proper guide in using these materials.
Glass Ionomer, Fluroshield, Teethmate-F and Concise were used as test materials and evaluations were performed by pH-ion meter, stereomicroscope and polarizing microscope for analyses of fluoride, microleakage and anticariogenicity respectively.
@ES The results can be summarized as follows :
@EN 1. The amount of fluorde release in each sealant group showed general pattern of decline. Glass Ionomer 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 Ionomer group showed the most severe degree of microleakage, whereas Concise group showed the least. Fluroshield demonstrated slightly less microleakage than Teethmate-F but with no statistical 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
Ionomer group.
4. In Glass Inoomer 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 group 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 for these materials to get wider access to clinical dentistry.
