Standardized cavities were prepared on 60 permanent teeth which had been selected
according to inherent fluoride ion content of enamel and several glass ionomers and
composite resins were restored. After classification and deposition for 1,2 and 3 weeks,
artificial caries was made on these specimens and resulting histologic appearances and
depths of the lesions were observed by a polarizing microscope. Then caries resistant
effects of each materials were compared and analyzed. In groups of Ketac-Fil and Fuji
¥±, the depth of lesion was increased markedly as the distance had been far away from
the margin of restoration materials, whereas in the control soup(Silux Plus), lesion depth
was deeper than the experimental group and uniform depth of lesion was made despite
of the distance from the margin. Fluoride ion content released in solution was higher in
Ketac-Fil, Fuji ¥±, Silux Plus by descending order and statistically significant difference
between groups could be found.
