Abstract

|
The purposes of this study were to analyze the effect of fluoride in vitro on the remineralization of artificial carious enamel by several pre-determined regimen and also to compare the degree of fluoride uptake into normal and carious enamel
during
those processes by quantitative analysis.
@ES The results from the present study can be summarized as follows ;
@EN 1. Analyses of fluoride uptake in various enamel samples after treatments were performed by enamel biopsy technique. Results showed general increase of fluoride level in all groups except group I. Eidence of greater affinity of fluoride to
carious
enamel over normal enamel was also shown in all three flurode-treated groups.
2. under polarizing light microscope, remineralization phenomena of artificial carious enamel were found in most of observed sample sections in varying degree, Samples in group IV did not show any significant recovery of lesion wherease two
fluoride
treated groups (group II and III) showed remarkable evidences of remineralization with significant reduction in lesion depth and positive birefringence. Group I revealed mild to moderate degree of remineralization in the deeper layer of lesion
body.
3. Line scan analyses through EPMA showed superior recovery of Ca/P intensity in group II and III to group I and IV, supporting the results of histological evaluation.
4. The significant increase of microhardness values over those of control lesion could be found in depth of about 85㎛ to 135㎛ of lesion. Samples in group IV had the lowest increment in hardness, while those in group II showed the larger
increment
than the ether groups.
5. Fvidences of reinineralization observed on enamel surfaces through scanning electron microscope were revealed as a general reduction in surface porosity along with some degree of surface deposits of crystal-like materials.
