초록
목적: 이 연구의 목적은 RMGIC에 레진 표면 코팅제를 적용하였을 때 용해도와 불소 유리량 간의 상관관계를 알아보는것이다. 연구 재료 및 방법: 불소 유리량과 용해도 측정을 위해 표면 코팅제를 도포하지 않은 Fuji II LC®, FiltekTM Z350XT와 G coat plusTM를 도포한 Fuji II LC®, Permaseal®를 도포한 Fuji II LC®를 준비하고 불소 유리량과 용해도를 측정하였다. 결과: 일간 불소 유리량은 표면 코팅제 간의 차이는 유의하지 않았다. 불소 누적 유리량은 56일에 RMGIC를 사용한 군에서 유의한 차이를 보였다(P < 0.05). 용해도 측정에서 표면 코팅제를 도포하지 않은 RMGIC가 다른 세 군에 비하여 7일 째에서만 유의한 차이를 보였다(P < 0.05). 결론: 표면 코팅제는 RMCIG에서 초기 용매에 의한 물성 저하를 막아 수복재 내부에 불소를 보존하며 추후 수복재의 불소의 방출과 저장에 대한 영향 또한 감소한다.
Abstract
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.
