Purpose:
To compare the fluoride levels released from a polyacid-modified resin composite (Ultra BandLok), a resin-modified glass-ionomer cement (Multicure) and a conventional glass-ionomer cement (Meron).
Methods:
Fluoride concentration in the deionized water was measured at 1, 2, 3, 7, 14 and 28 days. Fluoride measurement was undertaken using a fluoride ion selective electrode connected to an ion-analyzer. Friedman test was used in the repeated measurements of multiple groups. Kruskal-Wallis test was used to compare the groups. Dunn's multiple comparison test was applied for the comparison of subgroups.
Results:
The fluoride release pattern of the three materials was similar. The highest level of fluoride was obtained at the 24-hour measurement from all samples. According to comparisons among materials, Ultra BandLok released significantly less fluoride than Multicure and Meron (P < or = 0.01) at all the measurement times. In addition, the differences between the fluoride concentrations released from Multicure and Meron materials at all measurement days were not significant (P> 0.05).
