Purpose: This study aimed to investigate the correlation between the solubility and the amount of fluoride release when a resin surface coating agent is applied to RMGIC.
Materials and Methods: To measure the fluoride release and solubility, Fuji II LC®and FiltekTM Z350XT without a surface coating, Fuji II LC® with G coat plusTM and Fuji II LC® with Permaseal® were prepared. And the amount of fluoride release and solubility were measured.
Results: There was no significant difference in the daily fluoride release between the surface coating agents. The cumulative fluoride release was significantly different between the groups using RMGIC at 56 days (P <0.05). In the solubility measurement, RMGIC without surface coating was significantly different only on the 7th day compared to the other three groups (P < 0.05).
Conclusion: Surface coating agents can prevent the degradation of properties by the initial solvent in RMGIC. Therefore, fluoride is preserved inside the restorative material and the effect of surface coating after the addition is reduced, so that the effect on fluoride release and storage is also reduced.
