The objective was to evaluate new commercially available ion-releasing restorative materials and compare them to established anti-cariogenic materials. Four materials were tested: alkasite Cention (Ivoclar Vivadent) in self-cure or light-cure mode, giomer Beautifil II (Shofu), conventional glass-ionomer Fuji IX (GC), and resin composite Tetric EvoCeram (Ivoclar Vivadent) as a control. Flexural strength, flexural modulus, and Weibull modulus were measured one day, three months, and after three months with accelerated aging in ethanol. Water sorption and solubility were evaluated for up to one year. Degree of conversion was measured during 120 min for self-cured and light-cured Cention. In this study, Beautifil II was the ion-releasing material with the highest flexural strength and modulus and with the best resistance to aging. Alkasite Cention showed superior mechanical properties to Fuji IX. Weibull analysis showed that the glass-ionomer had the least reliable distribution of mechanical properties with the highest water sorption. The solubility of self-cured alkasite exceeded the permissible values according to ISO 4049. Degree of conversion of light-cured Cention was higher than in self-cure mode. The use of alkasite Cention is recommended only in the light-cure mode.
目的是评估新上市的可释放离子的修复材料,并将其与已有的抗龋材料进行比较。测试了四种材料:自固化或光固化模式下的碱土硅酸盐Cention(义获嘉伟瓦登特公司)、聚硅烷类玻璃离子复合体Beautifil II(松风公司)、传统玻璃离子水门汀Fuji IX(GC公司)以及树脂复合材料Tetric EvoCeram(义获嘉伟瓦登特公司)作为对照。在一天、三个月以及三个月后经乙醇加速老化后测量弯曲强度、弯曲模量和威布尔模量。评估长达一年的吸水率和溶解度。在120分钟内测量自固化和光固化Cention的转化率。在本研究中,Beautifil II是具有最高弯曲强度和模量且抗老化性能最佳的可释放离子材料。碱土硅酸盐Cention表现出优于Fuji IX的机械性能。威布尔分析表明,玻璃离子水门汀的机械性能分布最不可靠且吸水率最高。自固化碱土硅酸盐的溶解度超过了ISO 4049规定的允许值。光固化Cention的转化率高于自固化模式。仅建议在光固化模式下使用碱土硅酸盐Cention。
