Cention N의 물흡수도, 물용해도에 관한 비교분석

Abstract

Cention N was a recently introduced alkasite-based restorative material that was expected to replace amalgam and glass ionomer cement. This material was an esthetic restoration with adequate mechanical strength and release of fluoride and calcium. The purpose of this study was to measure the water sorption and water solubility of Cention N and evaluate its long-term durability compared to other esthetic restorations(resin-modified glass ionomer cement, giomer, composite resin). Cention N(CN), resin modified-glass ionomer cement(FJ), giomer(BF), and composite resin(FZ) were each made 20 specimens. After the specimen was completely dried for 24 hours using a vacuum pressure pump, the specimen was weighed (m1). After that, the specimen was immersed in distilled water at 37°C for 7 days, stored in a thermostat, and weighed (m2). After drying completely for 24 hours, the specimen was weighed (m3). It was calculated using the water absorption and water solubility calculation formulas.

When measuring water sorption, FJ (122.61 μg/mm) showed significantly higher water sorption than CN (35.42 μg/mm) (p<0.05). There was no significant difference between FZ (18.03 μg/mm) and BF (14.76 μg /mm) (p=0.930). When measuring water solubility, CN (6.65μg/mm) showed significantly higher water solubility than FJ (1.47 μg/mm) (p<0.05).

Cention N had lower water sorption than RMGIC, but higher water solubility. In addition, it was more vulnerable to moisture than Giomer and Composite resin, so it is considered appropriate to use it in consideration of long-term durability when used clinically.
