초록

The purpose of this study was to estimate the quantities of fluoride ions from glass ionomer cement(FLC), compomer
(DYT) and experimental composite resin containing NaF nanotube(0, 0.5, 1, 1.5%; EXP-1, EXP-2, EXP-3, EXP-4), and to
evaluate the effect of NaF nanotube on both fluoride releasing and microstructure of composite resin. Disk-typed specimens
were prepared and immersed in 10 ml distilled water(37℃) and fluoride release was measured after specific periods by using
the ion-selective electrode(ISE). The amounts of free fluoride ions released from specimens were measured by using the ion
chromatography(IC) after 28 days. The microstructure of specimens was examined by the SEM/EDS. The cumulative amount
of the fluoride-releasing was decreased FLC, DYT, EXP-4, EXP-3, EXP-2, EXP-1 by turns for 56 days. The fluoride
releasing of EXP-1 was little and EXP-4 was showed higher than EXP-2 and EXP-3. After 7 days the fluoride-releasing of
the FLC and DYT dropped rapidly, after 30 days the fluoride-releasing of the EXP was gradually increased. Generally, the
amount of fluoride-releasing was measured by ISE showed higher than using IC. The ratio of the free fluoride ions of the
FLC and DYT and EXP-4 was 33.1 %, 33.6 %, 90 % respectively, the ratio of the EXP-4 which containing 1.5% nanotube
was the highest. After 56 days the amount of the fluoride-releasing from the EXP-4 rapidly increased, and it approximates
the FLC and DYT.
